Although physical activity modulates the hypothalamic-pituitary-ovarian axis, the few studies that have investigated whether physical activity is associated with age at natural menopause have yielded mixed results. We set out to determine whether physical activity is associated with the timing of natural menopause in a large cohort of California women overall and by smoking history. We investigated the association between long-term physical activity (h/wk/y) and age at natural menopause among 97,945 women in the California Teachers Study. Multivariable Cox proportional hazards regression methods were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). The impact of cigarette smoking (never smoker, former light smoker, former heavy smoker, current light smoker, and current heavy smoker) as an effect modifier was evaluated. In a multivariable model adjusted for body mass index at age 18 years, age at menarche, race/ethnicity, and age at first full-term pregnancy, increased physical activity was statistically significantly associated with older age at natural menopause (P(trend) = 0.005). Higher body mass index at age 18 years (P(trend) = 0.0003) and older age at menarche (P(trend) = 0.0003) were also associated with older age at natural menopause. Hispanic ethnicity (vs non-Hispanic whites; HR, 1.17; 95% CI, 1.09-1.26), current smokers (vs never smokers; HR, 1.68; 95% CI, 1.60-1.75 for current light smokers; HR, 1.38; 95% CI, 1.33-1.44 for current heavy smokers), and older age at first full-term pregnancy (HR(≥29, 2+ full-term pregnancies) vs HR(<29, 2+ full-term pregnancies), 1.10; 95% CI, 1.06-1.14) were associated with earlier age at natural menopause. Upon stratification by smoking history, increased physical activity was statistically significantly associated with older age at natural menopause among heavy smokers only (HR(highest quartile) vs HR(lowest quartile), 0.88; 95% CI, 0.81-0.97; P(trend) = 0.02 for former heavy smokers; HR(highest quartile) vs HR(lowest quartile), 0.89; 95% CI, 0.80-0.99; P(trend) = 0.04 for current heavy smokers). Age at natural menopause is a complex trait; the determinants of age at natural menopause, including physical activity, may differ by smoking status.

Cigarette smokers, never-smokers, and transitions: implications for successful aging.

One of the social identities held by people is defined by whether or not they smoke cigarettes. Although this identity can and does change for many people over the course of their lives, most research has not examined the effects of transitioning from a smoker to a non-smoker. Using a life span perspective, our analyses contrasted the extent to which successful aging is experienced by: (1) persons who ever smoked and those who never smoked; (2) former smokers and current smokers; and (3) persons who transitioned from being a smoker to being a non-smoker at different ages. Using data from a random sample of 5688 persons between the ages of 50 and 74 living in New Jersey, we found that persons who never smoked were most likely to age successfully; there were no differences in patterns of successful aging when all former smokers were compared to current smokers; and persons who quit smoking before age 30 experienced modest benefits compared with those who continued to smoke.

To examine the relationship between the presence of smokers in the workplace and smokers in the home and current smoking status among employed men and women. Analysis of data from the second wave of the nationally representative Survey of Midlife Development in the United States (2004-2006). Sample of 627 currently employed men and women, aged 34 to 82 (M = 51), who had been regular cigarette smokers at some time. Survey items indexing presence of smokers in the respondents' immediate work area and home and their current smoking status. Multiple logistic regression analyses, controlling for age, gender, education, race, and job type. Examined together, smokers in the workplace (OR = 2.83) and smokers in the home (OR = 6.09) were uniquely associated with current smoking status. Moreover, smokers in the home reduced the association between smokers in the workplace and current smoking. The presence of smokers in the workplace was associated with a more than fourfold increase in current smoking among respondents with no smokers in the home, but was unrelated to current smoking among respondents with smokers in the home. Failure to consider the presence of smokers in the home significantly limits the potential impact of workplace smoking interventions.

BACKGROUND After declining for many years, the prevalence of smoking has remained stable over the past decade. One possible explanation is that there has been an increase in the prevalence of barriers to cessation, like depression, among remaining smokers. OBJECTIVES To estimate changes in the prevalence of depression among current, former and never smokers in the United States (U.S.) population from 2005 to 2013 overall and by age, gender, and income. METHODS Data were drawn from the National Household Survey on Drug Use (NSDUH), an annual cross-sectional study of persons ages 12 and over (N=496,805). The prevalence of past 12-month depression was examined annually among current (past 12-month), former (not past 12-month), and lifetime non-smokers from 2005 to 2013. Data were re-analyzed stratified by age, gender, and household income, and adjusted for demographics. RESULTS Depression appears to have significantly increased in the United States from 2005–2013 among current, former, and never smokers. Depression prevalence increased among current smokers overall, but the increase among former and never smokers was even more prominent. Striking temporal changes emerged by age, gender and income. Specifically, (1) depression increased significantly among current smokers aged 12–17 (from 16% to 22%, p-value=0.0002) and the prevalence was consistently more than twice as high as that of never smokers; (2) depression increased among male smokers (6.19% to 7.82%, p-value=0.0099); (3) depression increased significantly among smokers in the highest income group (6.36% to 8.91%, p-value=0.0400). Throughout this period, the prevalence of depression among current smokers was consistently twice as high as former and never smokers. DISCUSSION Public health efforts aimed at decreasing the prevalence of smoking should take depression into account, a common and modifiable barrier whose treatment may help to increase successful smoking cessation. Future work is needed to disentangle the role of smoking and other factors that lead to increases in depression in the US population. PMID:28209289

After declining sharply for many years, the prevalence of smoking has remained fairly stable over the past decade. One possible explanation is that there has been an increase in the prevalence of barriers to cessation, like depression, among remaining smokers.

Objective: To study the role of age plays in the relationship between smoking status and obesity in both Chinese men and women. Methods: From Chinese Physical and Psychological Database, participants were divided into non-smokers, current smokers, and former smokers. Body mass index (BMI), waist circumference (WC), fat percentage, fat mass, and fat free mass were measured. The mean, standard deviation and frequency of these indicators were calculated for each age bracket. One-way ANOVA and post-hoc test analyses were used to detect the difference among these three groups. Results: In men, from 19 to 24 years old, BMI, WC and fat free mass of current smokers were higher than that of non-smokers (P<0.01). However, fat mass and fat percentage of current smokers were lower than that of non-smokers but higher than that of former smokers (P<0.01). From 25 to 34 years old, BMI and fat mass of former smokers were higher than non-smokers and current smokers (P<0.01). In addition, WC and fat free mass of non-smokers were lower than that of current smokers and former smokers (P<0.01). From 45 to older, BMI, WC, fat mass, fat free mass and fat percentage of former smokers were higher than that of current smokers (P<0.01). From 55 to older, BMI, WC, fat mass, fat free mass and fat percentage of current smokers were lower than that of non-smokers (P<0.01). In women, smoking status might not be significantly related to obesity (P>0.05). Conclusion: For young men, smoking might have an effect on increasing fat free mass, BMI and WC, and decreasing fat mass and fat percentage. For middle and older men, smoking might have an effect on decreasing fat free mass, fat mass, BMI, WC, and fat percentage. Obesity risk should be paid more attention in smoking cessation programs for those former smokers. PMID:26770514

Objective To accurately assess the benefits of tobacco control interventions and to better inform decision makers, knowledge of medical expenditures by age, gender, and smoking status is essential. Method We propose an approach to distribute smoking-attributable expenditures by age, gender, and cigarette smoking status to reflect the known risks of smoking. We distribute hospitalization days for smoking-attributable diseases according to relative risks of smoking-attributable mortality, and use the method to determine national estimates of smoking-attributable expenditures by age, sex, and cigarette smoking status. Sensitivity analyses explored assumptions of the method. Results Both current and former smokers ages 75 and over have about 12 times the smoking-attributable expenditures of their current and former smoker counterparts 35–54 years of age. Within each age group, the expenditures of formers smokers are about 70% lower than current smokers. In sensitivity analysis, these results were not robust to large changes to the relative risks of smoking-attributable mortality which were used in the calculations. Conclusion Sex- and age-group-specific smoking expenditures reflect observed disease risk differences between current and former cigarette smokers and indicate that about 70% of current smokers’ excess medical care costs is preventable by quitting.

This study aimed to evaluate the relations of smoking with asthma and asthma-related symptoms, considering quantitative and temporal influences. The 820,710 Korean adults in the Korean Community Health Survey in 2009, 2010, 2011, and 2013 were included and classified as non-smoker, past smoker or current smoker. Total smoking years, total pack-years, and age at smoking onset were assessed. Information on wheezing, exercise wheezing, and aggravation of asthma in the past 12 months and asthma diagnosis history and current treatment was collected. Multiple logistic regression analysis with complex sampling was used. Current and former smokers showed significant positive relations with wheezing, exercise wheezing, asthma ever, current asthma, and asthma aggravation. Current smokers demonstrated higher adjusted odd ratios (AORs) for wheezing, exercise wheezing, and asthma aggravation than former smokers. Former smokers showed higher AORs than current smokers for current asthma treatment. Longer passive smoking was related to wheezing and exercise wheezing. Greater age at smoking onset and duration since cessation were negatively related to wheezing, exercise wheezing, and current asthma; total pack-years demonstrated proportional associations with these symptoms. Former, current, and passive smoking was positively correlated with wheezing and exercise wheezing. Total pack-years and early initiation were increasingly related to asthma.

To address the prevalence of lung cancer in high and low-risk people according to their smoking history, age, and CT findings of emphysema. We reviewed the baseline low-dose CT scans of 62,124 current, former and never smokers, aged 40-90 to determine the prevalence of lung cancer. We performed logistic regression analysis of the prevalence of lung cancer to determine the odds ratio (OR) for emphysema, conditionally on age, female gender, and ethnicity. The prevalence of lung cancer was 1.4% (95% CI: 1.3-1.6) for current smokers, 1.1% (95% CI: 1.0-1.2) for former smokers, and 0.4% (95% CI: 0.3-0.6) for never smokers. Emphysema was identified in 28.5% (6,684), 20.6% (5,422), and 1.6% (194) of current, former, and never smokers, respectively. The prevalence of lung cancer among current smokers was 1.1% for those without emphysema vs. 2.3% for those with emphysema (odds ratio [OR] 1.8; 95% confidence interval [CI]: 1.4-2.2) and the corresponding difference for former smokers was 0.9% vs. 1.8% (OR: 1.7; 95% CI: 1.3-2.2), and for never smokers, it was 0.4% vs. 2.6% (OR: 6.3; 95% CI: 2.4-16.9). Identification of emphysema in low-dose CT scans increases the risk of lung cancer and is important in determining follow-up of current, former, and never smokers.

Harmfulness of smoking on the human body leads to the development of tobacco-related diseases, which contributes to a reduction in years of life. Active smoker cigarettes more often suffers from ill-health, emotional state, physical function, social activity, than a non-smoker. These differences are even more pronounced among the elderly. The aim of the study was to compare the quality of life in middle-aged and elderly among chronic smokers and non-smokers. The study included 400 people who were divided into two groups: those in middle age (100-hundred active smokers and 100 never smokers people) and the elderly (100-hundred active smokers and 100 never smokers people). The average age of respondents - 43.5 years for people in middle age and 65.3 years at the old age. Number of cigarettes smoked per day 15 pieces in middle-aged and 7 cigarettes by older people. When comparing the health of middle-aged to older people, to 42.5% of younger people are happy with the current state of health, this percentage decreases to 10% in the elderly. The results showed that none among the elderly smokers not rated health status as good, among nonsmokers was 20% of the respondents. There was statistically significant differences: between active smokers and nonsmokers in middle age (p<0,004), and in old age (p<0.0001). Middle age, hypertension was diagnosed in 32% of current smokers and only in three non-smokers (p<0.001). Hypertension among older people occurred twice as often among smokers than nonsmokers, like coronary heart disease, and 31% of smokers in the elderly suffered from COPD, compared to 2% of non-smokers (p<0.001). Middle age 39% of smokers, feels great due to the limitation of physical health, the elderly, 58% is several times more likely than their peers in groups of non-smokers (p<0.001). The pain is more common in smokers than non- smokers in both age groups, this is the pain of a strong and medium intensity. Nonsmokers, independent of age often engaged in family and social life than smokers in the same age groups (p<0.001). Cigarette smokers have chronic diseases earlier, more often and more numerous than in the group of non-smoking peers. Worse physical and psychological health of smokers reduces social activity and decrease in quality of life.

Cigarette smoking has been associated with the risk of idiopathic pulmonary fibrosis (IPF). Certain comorbidities have been associated with reduced survival although some studies have indicated that current smokers have a longer survival than ex-smokers. Comorbidities in relation to smoking history have not been previously analyzed. Retrospective data was collected and patients were categorized according to gender and smoking habits. Comorbidities and medications were collected. Predictive values for mortality were identified by COX proportional hazard analyses. We examined 45 non-smokers (53.3% female), 66 ex-smokers (9.1% female) and 17 current smokers (17.6% female) with IPF. Current smokers were younger at baseline (58.1 ± 8.74 years) compared to non-smokers (71.4 ± 8.74, p < 0.001) and ex-smokers (72.5 ±7.95, p <0.001). Median survival of non-smokers and current smokers was longer (55.0 and 52.0 months, respectively) than that of ex-smokers (36.0 months) (p=0.028 and 0.034, respectively). In age and severity adjusted analyses, smoking was not related to survival. Cardiovascular diseases (CVD) (72.7 %) were the most common comorbidities, current smokers had more chronic obstructive pulmonary disease (COPD) and lung cancer compared to ex-smokers (p<0.001). CVD, COPD and use of insulin were related to poorer survival in adjusted analyses. Smoking seems to influence the course of disease in IPF since current smokers developed the disease at a younger age in comparison to non-smokers and ex-smokers. No significant differences in the major comorbidities were detected between IPF patients with different smoking histories. The mechanism through which smoking influences IPF progression requires further investigation.
Not All Smokers Die Young: A Model for Hidden Heterogeneity within the Human Population

The ability of some individuals to reach extreme old age in the presence of clearly high exposure to damaging factors may signal an innate biological advantage. For this study we used data on 4,655 current and never smokers, ages 50 and above, from NHANES III to examine whether long-lived smokers represent a biologically resilient phenotype that could facilitate our understanding of heterogeneity in the aging process. Using a proportional hazards model, our results showed that while smoking significantly increased mortality in most age groups, it did not increase the mortality risk for those who were age 80 and over at baseline. Additionally when comparing the adjusted means of biomarkers between never and current smokers, we found that long-lived smokers (80+) had similar inflammation, HDL, and lung function levels to never smokers. Given that factors which allow some individuals to withstand smoking may also enable others to cope with everyday biological stressors, the investigation of long-lived smokers may eventually allow us to identify molecular and genetic mechanisms which enable longevity extension.

The study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant. Survey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44years from the US. Half (n=400) reported current, daily smoking and half (n=400) reported smoking <100 cigarettes lifetime. Participants completed questionnaires regarding sociodemographics, tobacco/nicotine use, and impulsivity (i.e., delay discounting & Barratt Impulsiveness Scale). Predictors of smoking and e-cigarette use were examined using logistic regression. Daily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it was associated with greater impulsivity and illegal drug use. E-cigarette use was associated with hookah use, and for never smokers only with use of cigars and other nicotine products. E-cigarette use among women of reproductive age varies by smoking status, with use among current smokers reflecting attempts to quit smoking whereas among non-smokers use may be a marker of a more impulsive repertoire that includes greater use of alternative tobacco products and illegal drugs.

Data from National Health and Nutrition Examination Survey for 1999-2012 were used to evaluate factors that affect observed levels of blood cadmium (BCd) and urine cadmium (UCd) among former and current smokers aged 20-64 and ≥65 years. Adjusted levels (AGM) for BCd and UCd were higher among females as compared to males. The order of AGM for BCd by race/ethnicity for 20-64 years old was non-Hispanic white (NHW) < non-Hispanic black (NHB) and NHW > NHB for ≥65 years old. The order of AGMs for UCd for 20-64-year-old current smokers was NHW > NHB and NHW > NHB for former smokers. For 20-64-year-old current smokers, exposure to environmental tobacco smoke at home was associated with higher levels of BCd. Levels of both UCd and BCd increased with age, but the rate of increase was as much as seven times higher among ≥65 years old than 20-64 years old. For current smokers, the number of cigarettes smoked inside home was positively associated with the levels of BCd. For current smokers aged 20-64 years, the number of cigarettes smoked inside home was positively associated with the levels of UCd (p < 0.01), and the number of cigarettes smoked every day on the days they were smoked was also positively associated with the levels of UCd (p < 0.01). Among former smokers, levels of both UCd and BCd were positively associated (p < 0.1) with the number of cigarettes smoked per day at the time of quitting smoking and negatively associated with the time since smoking was quitted (p < 0.01).

Fractional exhaled nitric oxide (FE NO ) is used to assess of airway inflammation; diagnose asthma and monitor adherence to advised therapy. Reliable and accurate reference values for FE NO are needed for both non-smoking and current smoking adults in the clinical setting. The present study was performed to establish reference adult FE NO values among never-smokers, former smokers and current smokers. FE NO was measured in 5265 subjects aged 25-75 years in a general-population study, using a chemiluminescence (Niox ™) analyser according to the guidelines of the American Thoracic Society and the European Respiratory Society. Atopy was based on the presence of immunoglobulin E (IgE) antibodies to common inhalant allergens (measured using Phadiatop® test). Spirometry without bronchodilation was performed and forced vital capacity (FVC), forced expired volume in 1 s (FEV 1 ) and the ratio of FEV 1 to FVC values were obtained. After excluding subjects with asthma, chronic bronchitis, spirometric airway obstruction and current cold, 3378 subjects remained. Equations for predictions of FE NO values were modelled using nonparametric regression models. FE NO levels were similar in never-smokers and former smokers, and these two groups were therefore merged into a group termed "non-smokers". Reference equations, including the 5th and 95th percentiles, were generated for female and male non-smokers, based on age, height and atopy. Regression models for current smokers were unstable. Hence, the proposed reference values for current smokers are based on the univariate distribution of FE NO and fixed cut-off limits. Reference values for FE NO among respiratory healthy non-smokers should be outlined stratified for gender using individual reference values. For current smokers separate cut-off limits are proposed.

Younger age at menopause is associated with overall mortality, and cigarette smoking is the only lifestyle factor influencing this association. However, the combined effects of age at menopause and smoking have never been quantified in terms of survival time. Our aim was to evaluate, in a large cohort of Swedish women, differences in age at death according to age at menopause and smoking status. Age at menopause and smoking were assessed, using a self-administered questionnaire, in a population-based cohort of 25,474 women aged 48 to 83 years. Laplace regression was used to calculate differences in median age at death (50th percentile difference [PD]) according to smoking and age at menopause. Across 16 years of follow-up, 5,942 participants died. The difference in median age at death between women with menopause at 40 years and women with menopause at 60 years was 1.3 years (50th PD, 1.3; 95% CI, 0.3-2.2). Compared with current smokers, former smokers and never smokers had older median age at death-2.5 years (50th PD, 2.5; 95% CI, 1.9-3.1) and 3.6 years (50th PD, 3.6; 95% CI, 3.1-4.1), respectively. When analysis was restricted to current smokers, the difference in age at death between women with menopause at 40 years and women with menopause at 60 years increased to 2.6 years (50th PD, 2.6; 95% CI, 0.8-4.5). No association among never smokers was observed. Younger age at menopause is linearly associated with shorter survival. This association tends to be stronger among current smokers.

Objective Canada is among the few countries in which e-cigarettes containing nicotine are prohibited. To date, there is little evidence on the prevalence and patterns of use of e-cigarettes in markets with product bans. The current study examines e-cigarette use among a sample of non-smokers and smokers in Canada. Design Online cross-sectional survey. Setting Conducted in October 2013 using a commercial panel of Canadians from Global Market Insite, Inc (GMI). Participants In total, 1095 Canadians were included in the analysis: 311 non-smokers aged 16–24 years (younger non-smokers), 323 smokers aged 16–24 years (younger smokers) and 461 smokers 25 years and older (older smokers). Primary and secondary outcome measures E-cigarette ever and current use, types of products used, and reasons for use. Results Approximately 79% of younger non-smokers, 82% of younger smokers and 81% of older smokers were aware of e-cigarettes. Ever trial of e-cigarettes was reported by 10% of younger non-smokers, 42% of younger smokers and 27% of older smokers. Moreover, current use of an e-cigarette, which was defined as use in the last 30 days, was reported by 0.3% of younger non-smokers, 18% of younger smokers and 10% of older smokers. Among those who had ever tried an e-cigarette, approximately 10% of younger non-smokers, 46% of younger smokers and 43% of older smokers reported trying an e-cigarette that contained nicotine. The most popular e-cigarette flavours were fruit followed by menthol, and the most common reason for using e-cigarettes was to help them quit smoking. Conclusions In the context of previous research, it appears that the prevalence of e-cigarette trial has increased in Canada. Although a considerable proportion of non-smokers have tried e-cigarettes, current use is almost entirely concentrated among smokers. Further research should be conducted to monitor e-cigarette use by Canadians. PMID:26310400

Aims To examine the transitions in smoking status among nondaily smokers who transitioned to daily or former smokers or remained as nondaily smokers over a 12-month period. We analyzed factors associated with these transitions, including the use of cigars and smokeless tobacco (SLT). Design Secondary data analyses using pooled data from the 2003, 2006/07 and 2010/11 Tobacco Use Supplements to the Current Population Survey (TUS-CPS). Setting USA Participants Self-respondents aged 18+ who have smoked for more than 5 years and were nondaily smokers 12 months before the interview (n = 13,673 or 14.5% of current smokers). Measurements Multinomial logistic regression model to determine the correlates of nondaily-to-daily, stable nondaily, and nondaily-to-former smoking transitions among nondaily smokers at baseline. The model controlled for socio-demographic factors and the use of cigars and SLT. Findings 2.6% of adults in our sample were nondaily smokers at baseline. Among these, 69.7% remained nondaily smokers (stable nondaily smokers), 18.4% became daily smokers (nondaily-to-daily smokers), and 11.9% quit smoking (nondaily-to-former smokers) after 12 months. The nondaily-to-daily vs. stable nondaily smoking transition was less likely among those who were aged 65+ (p=0.018), male (p<0.001), Hispanic (p<0.001), with income of $25,000–49,999 or ≥$75,000, and current users of SLT (p=0.003), but more likely among those without a college degree compared with the appropriate reference group. The nondaily-to-former vs. stable nondaily smoking transition was less likely among those aged 25+, male (p=0.013), non-Hispanic Asian (p=0.032), without a college degree, widowed/divorced/separated (p=0.013) or never married (p=0.011), and current users of cigars (p=0.003) compared with the appropriate reference group. Conclusions While over two-thirds of nondaily smokers in the USA remain as such after 12 months, others become daily smokers or quit. The likelihood of remaining stable nondaily smokers and of transition from nondaily-to-daily and nondaily-to-former smokers is associated with socio-demographics factors and current use of cigars and smokeless tobacco.

Objectives: To describe smoking trajectories from early adolescence into mid-life and to examine the effects of these trajectories on health and all-cause mortality. Methods: A nationally representative birth cohort study including 3387 men and women followed up since their birth in 1946 in England, Scotland and Wales. The main outcome measure is all-cause mortality by age 60 years and rate of decline in forced expiratory volume in 1 second (FEV1). Results: Eighteen per cent of the sample were categorised as lifelong smokers (smokers at all six waves at ages 20, 25, 31, 36, 43, 53 years), of whom 90% had begun smoking by age 18 years. By age 60 years, 10% of all lifelong smokers had died. They had a threefold increase in mortality rate compared with never smokers (hazard ratio (HR) 3.2, 95% confidence interval (CI) 2.1 to 4.8). For predominantly smokers (smokers for at least four of the six data collections), mortality rate remained higher than never smokers (HR 1.6, 95% CI 1.0 to 2.5). Predominantly non-smokers did not differ from those who never smoked (HR 1.3, 95% CI 0.9 to 2.0). Using the most recent smoking status available, current smokers had more than double the risk of mortality compared with never smokers (HR 2.4, 95% CI 1.6 to 3.5). Lifelong smokers and predominantly smokers had a greater rate of decline in lung function than never smokers (regression coefficients −18 ml/year, 95% CI −22 to −13; −6, 95% CI −10.3 to −1.7 respectively). For current smokers, the decline was 8.4 ml/year (95% CI −12.0 to −5.0) faster than never smokers. Conclusions: The strength and differentiation of adverse effects identified by using simplified smoking behaviours has highlighted the advantages of obtaining further information on lifelong smoking behaviour from former smokers, rather than just current smoking status.

Cigarette smoking has been implicated in the pathophysiology of cardiovascular disease (CVD) and as a risk factor for erectile dysfunction (ED). However, various aspects of the associations between cigarette smoking, ED, and CVD need further elucidation. We explored the relationship between cigarette smoking, ED, and CVD using data from a population-based cross-sectional study of 1,580 participants. Postal questionnaires were sent to randomly selected age-stratified male population samples obtained from the Western Australia Electoral Roll. In addition to items covering sociodemographic and self-reported clinical information and smoking habits, the 5-item International Index of Erectile Function was used to assess erectile function. Compared with never smokers, the odds of ED, adjusted for age, square of age, and CVD, were significantly higher among current smokers (odds ratio [OR] = 1.40; 95% confidence interval [CI] 1.02, 1.92) and ever smokers (OR = 1.57; 95% CI 1.02, 2.42). Similarly, the adjusted odds of severe ED were significantly higher among former smokers. Albeit not statistically significant, the age-adjusted odds of ED among current smokers increased with the number of cigarettes smoked. Among former smokers, the age-adjusted odds of ED were significantly higher 6-10 years following cessation of smoking than < or = 5 or > 10 years. Compared with never smokers without CVD, the age-adjusted odds of ED among former smokers and ever smokers without CVD were about 1.6. Regardless of smoking, these odds were significantly higher among participants with CVD. Compared with never smokers, former smokers and ever smokers have significantly higher odds of ED. The relationship between smoking and ED is independent of that between smoking and CVD, and not because of confounding by CVD. Patterns of ED in former smokers suggest that there may be a latent interval between active smoking and symptomatic ED, involving a process initially triggered by smoking.

Electronic cigarettes (e-cigarettes) have gained popularity rapidly in the Western world but data in the East are scarce. We examined the awareness and ever use of e-cigarettes, and reasons for e-cigarette use in a probability sample of adults in Hong Kong. Cross-sectional data were collected in 2014 from Chinese adults aged 15-65 in Hong Kong (819 never smokers, 800 former smokers, 800 current smokers) via computer-assisted telephone interviews (response rate: 73.8%). Analysis was limited to a subset of 809 respondents (i.e., 357 never smokers, 269 former smokers, 183 current smokers) who were randomly selected to answer questions on e-cigarettes. Chi-square analyses compared e-cigarette awareness and ever use by gender, age, education, and cigarette smoking status. Multivariable logistic regression examined if e-cigarette awareness was associated with demographic variables and cigarette smoking status. 75.4% of adults had heard of e-cigarettes, and 2.3% reported having used e-cigarettes. Greater awareness was associated with male gender and higher education. Ever use of e-cigarettes was higher among males (3.6%, p=.03), younger adults (aged 15-29, 5.2%, p=.002), and current cigarette smokers (11.8%, p<.001). Common reasons for using e-cigarettes were curiosity (47.4%), the stylish product design (25.8%), and quitting smoking (13.6%). Awareness of e-cigarettes was widespread in Hong Kong. Although the use of e-cigarettes was low, its relation with younger age and current smoking is of concern. Health surveillance of e-cigarette use is needed. Interventions should target young adults and cigarette smokers, and address the marketing messages, especially the effect of e-cigarettes on smoking cessation. Copyright © 2015 Elsevier Ltd.

It is unclear whether use of electronic nicotine delivery systems (ENDS) precedes cigarette smoking initiation, relapse, and/or quitting. Healthcare systems with electronic health records (EHRs) provide unique data to examine ENDS use and changes in smoking. We examined the incidence of ENDS use (2012-2015) based on clinician documentation and tested whether EHR documented ENDS use is associated with twelve-month changes in patient smoking status using a matched retrospective cohort design. The sample was Kaiser Permanente Northern California (KPNC) patients aged ≥12 with documented ENDS use (N = 7926); 57% were current smokers, 35% former smokers, and 8% never-smokers. ENDS documentation incidence peaked in 2014 for current and former smokers and in 2015 for never-smokers. We matched patients with documented ENDS use to KPNC patients without documented ENDS use (N = 7926) on age, sex, race/ethnicity, and smoking status. Documented ENDS use predicted the likelihood of smoking in the following year. Among current smokers, ENDS use was associated with greater odds of quitting smoking (OR = 1.17, 95%CI = 1.05-1.31). Among former smokers, ENDS use was associated with greater odds of smoking relapse (OR = 1.53, 95%CI = 1.22-1.92). Among never-smokers, ENDS use was associated with greater odds of initiating smoking (OR = 7.41, 95%CI = 3.14-17.5). The overall number of current smokers at 12 months was slightly higher among patients with (N = 3931) versus without (N = 3850) documented ENDS use. Results support both potential harm reduction of ENDS use (quitting combustibles among current smokers) and potential for harm (relapse to combustibles among former smokers, initiation for never-smokers).

Smoking Cessation Is Associated With Lower Indirect Costs.
Baker, Christine L; Bruno, Marianna; Emir, Birol; Li, Vicky W; Goren, Amir
2018-06-01
This study quantified differences in indirect costs due to decreased work productivity between current and former smokers. Former smokers were further categorized by number of years since quitting to assess corresponding differences. Data on employed individuals were obtained from the 2013 US National Health and Wellness Survey (NHWS; N = 75,000). Indirect costs were calculated for current smokers and former smokers from weekly wages based on age and sex. The annual total indirect costs for current smokers were $1327.53, $1560.18, and $1839.87 higher than for those who quit 0 to 4 years, 5 to 10 years, and more than or equal to 11 years prior, respectively. There were no significant differences in mean total indirect costs between the former smoker groups. Current smokers showed significantly higher total annual indirect costs compared with former smokers, independently of the number of years since quitting smoking.

Introduction: Cigarette smoking has well known effects on body weight, with current smokers weighing less than never-smokers, and cessation producing weight gain. Use of waterpipe (or “hookah”) is increasing in many parts of the world but its effects on body weight are not known. Methods: We compared body mass index (BMI) among 2,536 adults (age ≥18 years old), who were never, former, current nondaily, or current daily waterpipe smokers, drawn from 2 representative, population-based household surveys of adults in Aleppo, Syria. Results: Overall, 84.1% (n = 2,134) never-smoked waterpipe, 4.6% (n = 116) were former smokers, 9.9% (n = 251) were current nondaily smokers, and 1.4% (n = 35) were current daily smokers. Mean BMI of the sample was 30.2kg/m2 (SD = 6.3). Adjusted for cigarette smoking, number of chronic diseases, age, gender, income, and marital status, daily waterpipe users were 2.26 BMI units greater than never-smokers (beta = 2.26, 95% CI = 0.79–3.72), and had nearly threefold odds of being obese (odds ratio = 2.87, 95% CI = 1.06–7.76). Nondaily and former waterpipe users were similar to never-smokers in terms of BMI and obesity risk. Conclusion: Results indicate that daily waterpipe users, compared to never-users, have higher BMI, translating into 6 extra kilograms of weight on average, and are 3 times as likely to be obese.

This study investigated the prevalence and correlates of electronic cigarettes (e-cigarettes) use in Taiwan. We studied a nationally representative random sample in the 2015 Taiwan Adult Smoking Behavior Survey. This study included 26 021 participants aged 15 years or older (51% women, 79% non-smokers, 16% aged 15-24 years), after excluding 31 persons (0.1%) who had missing information on e-cigarette use. The prevalence of ever having used e-cigarettes was calculated in the overall sample and by smoking status (current, former and never) or age (15-24, 25-44 and ≥45 years). We performed multivariable log-binomial regression to assess correlates of ever having used e-cigarettes among all participants and separately for subgroups by smoking status and age. Approximately 3% of all participants had ever used e-cigarettes. The prevalence of ever having used e-cigarettes was high in current smokers (14%) and people aged 18-24 years (7%). E-cigarette use was particularly common in people aged 15-24 years who were current (49-52%) or former (22-39%) smokers. Ever having used e-cigarettes was positively associated with tobacco smoking (adjusted prevalence ratio (aPR): 21.5, 95% CI 15.4 to 29.8, current smokers; aPR: 8.3, 95% CI 15.2 to 13.1, former smokers), younger age and high socioeconomic status. Age remained a significant factor of ever having used e-cigarettes across smoking status groups. Among non-smokers, men had a 2.4-fold (95% CI 1.5 to 3.8) greater prevalence of e-cigarette use than women. E-cigarette use was uncommon in the general population in Taiwan, but prevalence was high among smokers and young people. This study highlights challenges that e-cigarettes pose to tobacco control, which warrant high priority action by policymakers and public health professionals. E-cigarette regulations should focus on young people. Published by the BMJ Publishing Group Limited.

Trajectories of Cigarette Smoking From Adolescence to Adulthood as Predictors of Unemployment Status
Zhang, Chenshu; Burke, Lindsay; Brook, David W.
2014-01-01
Introduction: This longitudinal study examined the association between trajectories of cigarette smoking and unemployment across a 29-year time period from mean age 14 to mean age 43. Methods: Participants came from a community-based random sample of residents in 2 upstate New York counties. Data were collected at 7 timepoints. Results: Using growth mixture modeling, 5 trajectory groups of cigarette smokers were identified. The trajectory groups were as follows: heavy/continuous smokers, occasional smokers, late-starting smokers, quitters/decreasers, and nonsmokers. Multivariate logistic regression analysis was used to study the relationship between the participant’s trajectory group membership and unemployment in the fifth decade of life. The association was determined with controls for age, gender, current cigarette use, current alcohol use, current marijuana use, physical diseases, occupation, educational level, past unemployment experience, socioeconomic status measures of family of origin, depressive mood, and self-control from adolescence through the early 40s. The findings indicate that patterns of adolescent and young adult cigarette smoking have implications for later unemployment. Overall, the results showed that people who fell into the categories of heavy/continuous smokers (adjusted odds ratio [AOR] = 3.84) and occasional smokers (AOR = 4.03) were more likely to be unemployed at mean age 43 when compared with nonsmokers. There was no significant difference between the quitters/decreasers and the nonsmokers with respect to unemployment. Conclusions: Intervention programs designed to deal with unemployment should consider focusing on heavy/continuous and occasional cigarette smokers as risk factors for unemployment. PMID:24997307

We studied characteristics of past smokers according to the duration of cessation of smoking based on data from a population-based survey. Lifestyle, prevalences of various symptoms and diseases and other factors were compared among current smokers (8507 males and 2012 females), past smokers (4423 males and 684 females) and non-smokers (2431 males and 12,859 females) aged 40 years and over. Compared to current smokers, past smokers consumed more bread, milk, vegetables, fruit and black tea, and less rice, pickles, instant noodles, coffee and alcohol, had lower prevalences of cough, sputum and anorexia, participated more in cancer screening tests, weighed more, included more professional and administrative workers and had more non-smoking spouses. These characteristics resembled those of non-smokers. But past smokers had high prevalences of several cardiovascular and respiratory diseases compared to current smokers. Daily intake of coffee was inversely associated and daily intakes of fruit and milk were positively associated with the duration of abstinence from smoking after adjusting for other factors in both sexes. These results suggest that lifestyle of past smokers may contribute to risk reduction for several diseases.

Currently, the 5-year survival rate for rectal cancer remains at <60%. The identification of potentially modifiable prognostic factors would be of considerable public health importance. A few studies have suggested associations between smoking and survival in rectal cancer; however, the evidence is inconsistent, and most of these studies were relatively small. In a large population-based cohort study, we investigated whether smoking at diagnosis is an independent prognostic factor for cancer-specific survival in rectal cancer and whether the association varies by sex, age, or treatment. Rectal cancers (ICD10 C19-20) diagnosed between 1994 and 2012 were abstracted from the National Cancer Registry Ireland and classified by smoking status at diagnosis. Follow-up was for 5 years or until December 31, 2012. Multivariable Cox proportional hazards models were used to compare cancer-specific death rates in current smokers, ex-smokers, and never smokers. Subgroup analyses by age at diagnosis, sex, and treatment were conducted. A total of 10,794 rectal cancers were diagnosed. At diagnosis, 25% were current smokers, 24% were ex-smokers, and 51% were never smokers. Compared with never smokers, current smokers had a significantly greater rate of death from cancer (multivariable hazard ratio [HR], 1.15; 95% confidence interval [CI], 1.06-1.24), but ex-smokers did not (HR, 1.02; 95% CI, 0.94-1.11). The association was slightly stronger in men (current versus never smokers: HR = 1.13, 95% CI, 1.02-1.24) than females (HR, 1.05; 95% CI, 0.90-1.23), but the test for interaction was not significant (P = .75). The effect of smoking was not modified by age or receipt of tumor-directed surgery, radiotherapy, or chemotherapy. Rectal cancer patients who smoke at diagnosis have a statistically significant increased cancer death rate. Elucidation of the underlying mechanisms is urgently required.

Cigarette smoking negatively affects bone quality and increases fracture risk. Little is known on the effect of smoking cessation and computed tomography (CT)-derived bone mineral density (BMD) decline in the spine. We evaluated the association of current and former smoking with BMD decline after 3-year follow-up. Male current and former smokers participating in a lung cancer screening trial who underwent baseline and 3-year follow-up CT were included. BMD was measured by manual placement of a region of interest in the first lumbar vertebra and expressed in Hounsfield Unit (HU). Multiple linear regression analysis was used to evaluate the association between pack years smoked and smoking status with BMD decline. 408 participants were included with median (25th-75th percentile) age of 59.4 (55.9-63.5) years. At the start of the study, 197 (48.3%) participants were current smokers and 211 (51.7%) were former smokers and had a similar amount of pack years. Current smokers had quit smoking for 6 (4-8) years prior to inclusion. There was no difference in BMD between current and former smokers at baseline (109±34 HU vs. 108±32 HU, p=0.96). At 3-year follow-up, current smokers had a mean BMD decline of -3±13 HU (p=0.001), while BMD in former smokers did not change as compared to baseline (1±13 HU, p=0.34). After adjustment for BMD at baseline and body mass index, current smoking was independently associated with BMD decline (-3.8 HU, p=0.003). Age, pack years, and the presence of a fracture at baseline did not associate with BMD decline. Current smokers showed a more rapid BMD decline over a 3-year period compared to former smokers. This information might be important to identify subjects at risk for osteoporosis and emphasizes the importance of smoking cessation in light of BMD decline. Copyright © 2017 Elsevier B.V.

i) To determine the prevalence of smoking among the community aged 15 and above in Kg. Jenderam Hilir in Sepang District, Selangor state. ii) To determine the relationship between smoking and age, sex, household income and education. iii) To determine the parental and peer influence on smoking in Kg Jenderam Hilir. A study was conducted in Kg. Jenderam Hilir, Sepang. All residents aged 15 years and above from all the 381 households of Kg. Jenderam Hilir were included in this study. A standardized pre-tested structured questionnaire was used in this study. Out of 894 respondents interviewed 69% were males compared to 3.9% of the females (overall 33.6%) reported to have smoked at least once in his/her lifetime. The difference was statistically significant. The mean duration of smoking was 17.7 years. The age at which smoking was first attempted ranged from 4 years to 51 years with a mean of 18.7 years. The mean initiation age for the males was significantly lower as compared to the mean initiation age for the females. The prevalence of current smokers was significantly higher amongst males (52.8%) as compared to the females (1.4%). The prevalence of smoking among current smokers increased with age (p < 0.01). There was no significant difference in the prevalence of smoking by household income and educational level. The mean number of cigarettes smoked by males was significantly higher than the females (p < 0.05). The mean duration of smoking among current smokers was 20 years. There was a significant difference in the level of addiction to smoking and the duration of smoking (p < 0.05). The high level of addiction increased with the duration of smoking (p < 0.05). Sixty five percent of the current smokers reported to have tried to quit smoking while 26% of ever smokers had reported to quit smoking and remained nonsmokers. The quit ratio was calculated to be 26.0%. The quit ratio was 52.6% among those with college or university education. There was a significant difference in the quit ratio by education level (p < 0.01). There was no significant difference in smokers whose parents were smokers as compared to nonsmokers whose parents were smokers. However, there was a significant association between smoking and peer influence (p < 0.01).

Abstract Smoking is common in patients with HIV and is associated with increased morbidity and mortality. With the goal of targeting future cessation interventions, we sought to identify factors associated with smoking status, readiness and confidence in cessation, and success in quitting. As part of a larger study in New York City assessing predictors of chronic obstructive pulmonary disease (COPD), we enrolled HIV-infected subjects at least 35 years of age without known asthma or COPD. Current smokers received detailed tobacco history, and smoking status was assessed by chart review at 3 and 6 months post-enrollment. Two hundred subjects were enrolled (29% current smokers, 31.5% never smokers, 39.5% former smokers, mean age of 49, 84% male, 64% had AIDS, and 97% were receiving antiretroviral therapy). Current smokers had higher unemployment and increased rates of other substance use than former smokers or never smokers. In multivariate analysis, being unemployed and having used inhalant drugs were associated with current smoking. Substance abuse history was not correlated with readiness to quit or patient estimated cessation. Lower education was associated with decreased readiness to quit. Follow-up smoking status for baseline current smokers was available for 47/58 enrollees at 6 months; 4 (9%) stopped smoking completely, and 17 (36%) decreased the number of packs-per-day. Smoking and concomitant substance abuse is common in HIV, and special attention should be given to this issue, in addition to a patient's readiness to quit, when implementing tobacco cessation protocols, especially in busy urban HIV care centers.

The smoking rates and patterns in the North Korean population are not well known. More than 20,000 North Korean defectors have settled in South Korea; thus, we can estimate the current North Korean smoking situation using this group. All North Korean defectors spend their first 3 months in a South Korean facility learning to adapt to their new home. We retrospectively analyzed the results from a questionnaire conducted among North Korean male defectors in this facility from August 2012 to February 2014. Of 272 men, 84.2% were current smokers, 12.5% were ex-smokers, and 3.3% were non-smokers. The mean age of this group was 35.9 ± 11.3 years, and smoking initiation occurred at a mean age of 18.2 ± 4.7 years. Among the subjects, 78.1% had a family member who smoked. Of the 221 current smokers, 67.4% responded that they intended to quit smoking. Fagerström test and Kano test for social nicotine dependence (KTSND) results for current smokers were 3.35 ± 2.26 and 13.76 ± 4.87, respectively. Question 9 on the KTSND (doctors exaggerate the ill effects of smoking) earned a significantly higher score relative to the other questions and a significantly higher score in current smokers compared with non-smokers. The smoking rate in North Korean male defectors was higher than that indicated previously. However, interest in smoking cessation was high and nicotine dependence was less severe than expected. Further investigation is needed to identify an efficient method for North Korean smokers to stop smoking.

Based on current recommendations, 30+ pack-years of smoking are required for eligibility for low-dose CT (LDCT) lung cancer screening; former smokers must have quit within 15 years. We investigated whether current smokers with 20 to 29 pack-years have similar lung cancer risks as eligible former smokers and also whether they have a different demographic profile. The Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) was a randomly assigned screening trial of subjects age 55 to 74 years with chest radiographs (CXR) used for lung cancer. Subjects completed a baseline questionnaire containing smoking history questions. Cox proportional hazards models, adjusted for age and sex, were utilized to estimate hazard ratios (HRs) for various smoking history groups. Next, we utilized the National Health Interview Survey (NHIS), which inquired about smoking history and race/ethnicity, to analyze the demographic profiles of various high-risk smoking history categories. All statistical tests were two-sided. The PLCO cohort included 18 114 former and 12 243 current LDCT-eligible smokers, plus 2283 20- to 29-pack-year current smokers. The hazard ratio for 20- to 29-pack-year current smokers compared with eligible (30+ pack-year) former smokers was 1.07 (95% confidence interval [CI] = 0.75 to 1.5). Based on the NHIS, 10 million persons in the United States are currently LDCT eligible; an additional 1.6 million (16%, 95% CI = 13.6% to 19.0%) are 20- to 29-pack-year current smokers. The percentage increase in eligibles if 20- to 29-pack-year current smokers were included was substantially greater for women than men (22.2%, 95% CI = 17.9% to 26.7%; vs 12.2%, 95% CI = 9.3% to 15.3%, P < .001) and for minorities than non-Hispanic whites (30.0%, 95% CI = 24.2% to 36.0%; vs 14.1%, 95% CI = 11.1% to 17.0%, P < .001). The potential benefits and harms of recommending LDCT screening for 20 to 29-pack-year current smokers should be assessed. Published by Oxford University Press 2015.

In patients with asthma, smoking has been associated with accelerated decline in pulmonary function, poor disease control and reduced responsiveness to corticosteroids. To assess the influence of current and former smoking on self-reported asthma control and health care use in a large population of asthma patients. The present analysis was conducted following a telephone survey of adult Canadians aged 18 to 54 years who had physician-diagnosed asthma and a smoking history of less than 20 pack-years. Of 893 patients, 268 were former smokers and 108 were current smokers. Daytime and nighttime symptoms, absenteeism from work or school, emergency care use for asthma in the past year, and use of a short-acting bronchodilator without controller medication were reported more frequently by current smokers than nonsmokers and former smokers. Former smokers were not significantly different from nonsmokers with respect to most asthma outcomes. Current smokers with asthma show evidence of poorer asthma control and greater acute care needs than lifelong nonsmokers or former smokers. These observations stress the importance of smoking cessation to help achieve asthma control.

Interpretation of longitudinal information about lung function decline from middle to older age has been limited by loss to follow-up that may be correlated with baseline lung function or the rate of decline. We conducted these analyses to estimate age-related decline in lung function across groups of race, sex, and smoking status while accounting for dropout from the Atherosclerosis Risk in Communities Study. We analyzed data from 13,896 black and white participants, aged 45-64 years at the 1987-1989 baseline clinical examination. Using spirometry data collected at baseline and two follow-up visits, we estimated annual population-averaged mean changes in forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) by race, sex, and smoking status using inverse-probability-weighted independence estimating equations conditioning-on-being-alive. Estimated rates of FEV1 decline estimated using inverse-probability-weighted independence estimating equations conditioning on being alive were higher among white than black participants at age 45 years (e.g., male never smokers: black: -29.5 ml/year; white: -51.9 ml/year), but higher among black than white participants by age 75 (black: -51.2 ml/year; white: -26). Observed differences by race were more pronounced among men than among women. By smoking status, FEV1 declines were larger among current than former or never smokers at age 45 across all categories of race and sex. By age 60, FEV1 decline was larger among former and never than current smokers. Estimated annual declines generated using unweighted generalized estimating equations were smaller for current smokers at younger ages in all four groups of race and sex compared with results from weighted analyses that accounted for attrition. Using methods accounting for dropout from an approximately 25-year health study, estimated rates of lung function decline varied by age, race, sex, and smoking status, with largest declines observed among current smokers at younger ages.

There are no data comparing the relationship between coronary artery calcification and self-reported and cotinine-verified smoking. This study was carried out to evaluate the relationship between coronary artery calcium (CAC) and urinary cotinine or self-reported smoking status in Korean adults. Study participants included 22 797 individuals (19 181 men; mean age±SD 39.2±7.1 years) who were enrolled in the Kangbuk Samsung Health Study and Kangbuk Samsung Cohort Study between 2011 and 2013, and who had urinary cotinine and CAC measurements. Cotinine-verified current smokers were defined as having a urinary cotinine level of above 50 ng/ml. The prevalence of never smokers, former smokers, and current smokers according to the self-reported questionnaires was 44.6, 24.2, and 31.2%, respectively, and that of cotinine-verified current smokers was 30.2%. The prevalence of the presence of CAC in self-reported current smokers was higher than that in self-reported never/former smokers (13.7 vs. 10.2%, P<0.001), and that in cotinine-verified current smokers was higher than that in cotinine-verified never smokers (14.0 vs. 10.2%, P<0.001). A multivariate logistic regression model adjusted for the variables with univariate relationships showed that self-reported former smokers and current smokers had significantly increased odds ratio (OR) for the presence of CAC compared with self-reported never smokers [OR (95% confidence interval): 1.20 (1.03-1.40) in former smokers and 1.29 (1.11-1.50) in current smokers]. Cotinine-verified current smokers also showed a significant association with the presence of CAC [1.23 (1.12-1.35)]. Furthermore, log-transformed cotinine levels increased the OR for the presence of CAC [1.03 (1.01-1.05)]. This study is the first large cohort study to show that both self-reported and cotinine-verified smoking is associated independently with the presence of CAC in Korean adults.

Smoking is associated with significant health and economic burden globally, including an increased risk of many leading causes of mortality and significant impairments in work productivity. This burden is attenuated by successful tobacco cessation, including reduced risk of disease and improved productivity. The current study aimed to show the benefits of smoking cessation for workplace productivity and decreased costs associated with loss of work impairment. The data source was the 2011 Japan National Health and Wellness Survey (n = 30,000). Respondents aged 20-64 were used in the analyses (n = 23,738) and were categorized into: current smokers, former smokers, and never smokers. Generalized linear models controlling for demographics and health characteristics examined the relationship of smoking status with the Work Productivity and Activity Impairment questionnaire (WPAI-GH) endpoints, as well as estimated indirect costs. Current smokers reported the greatest overall work impairment, including absenteeism (i.e. work time missed) and presenteeism (i.e. impairment while at work); however, after controlling for covariates, there were no significant differences between former smokers and never smokers on overall work impairment. Current smokers and former smokers had greater activity impairment (i.e. impairment in daily activities) than never smokers. Current smokers reported the highest indirect costs (i.e. costs associated with work impairment); however, after controlling for covariates, there were no significant differences between former smokers and never smokers on indirect costs. Smoking exerts a large health and economic burden; however, smoking cessation attenuates this burden. The current study provides important further evidence of this association, with former smokers appearing statistically indistinguishable from never smokers in terms of work productivity loss and associated indirect costs among a large representative sample of Japanese workers. This report highlights the workplace benefits of smoking cessation across productivity markers and cost-savings.

The proportion of smokers who do not smoke daily has increased over time, but nondaily smokers are a heterogeneous group. We compare characteristics and other tobacco product use of infrequent nondaily, frequent nondaily, and daily US adult smokers. We analyzed data from the 1998, 2000, 2005, and 2010 National Health Interview Surveys. Current smokers were categorized as daily, infrequent nondaily (smoked 1-12 days in the past 30 days), and frequent nondaily (smoked 13-29 days in the past 30 days) smokers. Multinomial logistic regression analysis was used to analyze the correlates of infrequent nondaily, frequent nondaily, and daily smoking. Among current smokers, 8.3% were infrequent nondaily, 8.1% were frequent nondaily, and 83.6% were daily smokers. The prevalence of infrequent versus daily smoking increased over time, with a smaller increase among non-Hispanic Blacks than non-Hispanic Whites. The adjusted odds of both infrequent and frequent smoking versus daily smoking differed by age, race/ethnicity, education, poverty status, marital status, region, quit attempts in the past 12 months, and binge drinking. Snuff users (vs. non-snuff users) were 2.4 times as likely to be infrequent than daily smokers. There were also differences in race/ethnicity, education, marital status, region, quit attempts, and snuff use between infrequent versus frequent smokers. Infrequent smokers differ from both frequent and daily smokers in socio-demographics, quit attempts, and snuff use. The heterogeneity of nondaily smokers should be considered in developing targeted tobacco control and smoking cessation programs. Infrequent and frequent nondaily smokers were found to differ from daily smokers in age, race/ethnicity, education, poverty status, marital status, region, and quit attempts and they were different from each other in race/ethnicity, education, marital status, region, and quit attempts. Binge drinkers were more likely to be infrequent smokers and frequent smokers versus daily smokers. Current snuff users were found to have increased odds of infrequent smoking versus daily smoking and versus frequent smoking. These results highlight the importance of acknowledging the differences among nondaily smokers in smoking frequency in developing targeted tobacco control and smoking cessation programs.

Smoking is seen as the most important single risk to health today, and is responsible for a high financial burden on healthcare systems and society. This population-based cross-sectional study compares healthcare utilisation, direct medical costs, and costs of productivity losses for different smoking groups: current smokers, former smokers, and never smokers. Using a bottom-up approach, data were taken from the German KORA F4 study (2006/2008) on self-reported healthcare utilisation and work absence due to illness for 3,071 adults aged 32-81 years. Unit costs from a societal perspective were applied to utilisation. Utilisation and resulting costs were compared across different smoking groups using generalised linear models to adjust for age, sex, education, alcohol consumption and physical activity. Average annual total costs per survey participant were estimated as €3,844 [95% confidence interval: 3,447-4,233], and differed considerably between smoking groups with never smokers showing €3,237 [2,802-3,735] and former smokers causing €4,398 [3,796-5,058]. There was a positive effect of current and former smoking on the utilisation of healthcare services and on direct and indirect costs. Total annual costs were more than 20% higher (p<0.05) for current smokers and 35% higher (p<0.01) for former smokers compared with never smokers, which corresponds to annual excess costs of €743 and €1,108 per current and former smoker, respectively. Results indicate that excess costs for current and former smokers impose a large burden on society, and that previous top-down cost approaches produced lower estimates for the costs of care for smoking-related diseases. Efforts must be focused on prevention of smoking to achieve sustainable containment on behalf of the public interest.
Perceptions of young Jordanian adults to proposed anti-tobacco pictorial warning labels
2011-01-01
Background In commitment to the Framework Convention on Tobacco Control (FCTC), four new pictorial warnings are now being proposed for display on cigarette packages sold in Jordan. The aim of this study was to gauge the immediate perceptions of young Jordanian adults towards these new pictorials and compare these perceptions to those of the pictorial currently being used in the country. Methods A cross-sectional survey was conducted on a convenience sample of youth aged 17-26. The interviewer-administered survey gauged participants' perceptions of salience, fear elicitation, and gained information as well as participants' motivation to remain non-smokers or quit smoking after viewing each of the four proposed new pictorials as well as the current pictorial used in Jordan. Perceptions regarding each new pictorial were compared to the current pictorial. Results A total of 450 surveys were included in the analysis. The sample (mean age 20.9) was 51.6% female and 31.3% cigarette (regular or occasional) smokers. In smokers, only one proposed pictorial had significantly more smokers perceiving it as salient or adding to information when compared to the current pictorial. More smokers reported fear when observing the proposed pictorials compared with current pictorial, but overall proportions reporting fear were generally less than 50%. Furthermore, all new pictorials motivated significantly more smokers to consider quitting compared with the current pictorial; however, the overall proportion of smokers reporting motivation was < 25%. Among nonsmokers, significantly more respondents perceived the new pictorials as salient and fear-eliciting compared to the old pictorial, but there were no major differences in information added. Motivation to remain non-smokers was comparable between the old and new pictorials. Conclusion Given the variability of response across both smokers and nonsmokers, and across the three elements of perception (salience, added information, fear) for each pictorial, further testing of the pictorials in a more diverse sample of Jordanian young adults prior to launch is recommended.

We examined the knowledge regarding heavy drinking and smoking as risk factors of stroke according to drinking/smoking habits among randomly selected Japanese general population. The Japan Stroke Association and co-researchers have performed a large-scale educational intervention to improve knowledge concerning stroke from 2006 to 2008. Prior to above-mentioned intervention, we conducted mail-surveillance on knowledge about stroke in 11,306 randomly selected residents aged 40 to 74. We assessed the relationship between drinking/smoking habits and knowledge regarding heavy drinking and smoking as risk factors by using the chi-square test and multiple logistic regression analysis adjusting for age, sex, area, employment, living situation, history of stroke and other stroke related diseases, history of liver disease, family history of stroke and drinking (non-drinker / ex-drinker / occasional drinker / habitual drinker) / smoking habits (non-smoker / ex-smoker / current smoker). Total 5,540 subjects (49.0%) participated in this study. Ex-smokers and current smokers had better knowledge regarding smoking as a risk factor of stroke than non-smokers (odds ratio and 95% confidence intervals: 1.89, 1.55-2.31, 1.76, 1.45-2.12, respectively). There was no difference between habitual drinkers and non-drinkers in their knowledge, whereas current smokers had greater knowledge regarding smoking than nonsmokers. Accordingly, it is suggested that it will be necessary for habitual drinkers to be enlightened regarding heavy drinking as a risk factor of stroke and for current smokers to be provided with information regarding not only these risks but also the specific strategies for invoking behavioral changes.

Smoking in women is a well-recognized public health problem. In many developed countries, cigarette smoking is now the single most important preventable cause of premature death in women. There are relatively few data on the epidemiology of cigarette smoking in Asian women, and this study examined the prevalence of and factors predisposing Chinese women to smoke cigarettes in Hong Kong. A territory-wide random telephone survey of 26,716 households in Hong Kong was conducted. A total of 1064 current smokers and 291 ex-smokers were identified in these household, and in-depth interviews of 791 current smokers, 221 ex-smokers, and 1012 controls were conducted. The prevalence of cigarette smoking was 4.5% in women who were 25 years or younger, 2.6% in women aged 46-65 years, and 2.2% in women aged 65 years or older. Sixty-four percent of current smokers started when they were 19 years or younger. The main reasons for the initiation of cigarette smoking were the influence of friends, curiosity, feeling bored, or being idle. Current smokers and ex-smokers tended to have positive images of women who smoked. The following risk factors were found to be significant for cigarette smoking: less than university education, unemployment, being divorced, having a husband who smoked, and a low score on the perceived harms of cigarette smoking. Cigarette smoking is more prevalent in younger women in Hong Kong; and psychosocial issues should be addressed to prevent future epidemics.

The objective of this study is to describe the distribution of smoking in the population and to assess changes and trends over recent decades. Cross sectional study in a sample of the non-institutionalized resident population (n=3,509) in Barcelona (Catalonia, Spain) using data from persons over 14 years of age from the health survey of 2011, and assessing trends for 1983-2011 using previous surveys. Dependent variables are having ever been a smoker, having quit, being a current smoker, and smoking daily. Independent variables include sex, age, and time. Prevalence and proportions are estimated, stratifying or adjusting for age. The prevalence of daily smokers is 18.8% in 2011: 22.2% for men and 15.9% for women. The age groups with higher smoking prevalence are 25-34 years for men and 15-24 for women. From 1983 to 2011 the reduction among men has been intense, and for women the prevalence has been decreasing since the survey of 2000. Among smokers, the proportion of both genders who do not smoke daily has increased. The smoking epidemic over the last years shows promising trends. The data do not lend support to the hardening hypothesis for current smokers. Smokers are a shrinking minority, although to improve public health it would be desirable to speed the process of change.

National surveys show a low prevalence of tobacco cigarette smoking within the Asian American/Pacific Islander population. However, smoking rates loom higher when data is disaggregated by ethnicity and gender. Nevertheless, few data are available on how smokers in this population quit smoking. The aim of this study was to collect first-hand perspectives from adult male Chinese and Vietnamese current and former smokers who were patients at a community clinic in Seattle, Washington, in order to understand the facilitators toward smoking cessation and the methods that they might use to quit smoking. A telephone survey was administered to age-eligible male Chinese and Vietnamese clinic patients who were current or former smokers. A total of 196 Chinese and 198 Vietnamese (N=394) adult male current and former smokers were contacted from a pool culled from the clinic database. Descriptive analysis using SPSS software revealed ethnicity-specific differences between current and former smokers regarding influences on smoking cessation behavior as well as uptake and endorsement of cessation methods. Family encouragement and physician recommendations were significant facilitators on the cessation process. Will power and self-determination were frequently mentioned by both Vietnamese and Chinese smokers as helpful methods to quit smoking. Vietnamese smokers were more resourceful than Chinese smokers in their use of smoking cessation methods. Even with access to cessation classes at a health clinic, half of current smokers indicated that they had no intention to quit. Such attitudes underscore the need for promotion of effective smoking cessation programs as well as successful strategies for reaching smokers. These conclusions are particularly important for Chinese smokers, who were comparatively less resourceful in their use of smoking cessation methods. Future studies should explore integrating the concept of will power with current mainstream state-of-the-art smoking cessation programs.
Adolescent cigarette smokers' and non-cigarette smokers' use of alternative tobacco products.
Saunders, Charles; Geletko, Karen
2012-08-01
This study uses the most recent data from the nationally representative National Youth Tobacco Survey (NYTS) to examine the use of alternative tobacco products among U.S. cigarette smokers and non-cigarette smokers aged 14-17. Alternative tobacco product use is defined as use of one or more of the following products: smokeless tobacco, cigars, pipes, bidis, or kreteks. Using the results from the 2004, 2006, and 2009 NYTS, multivariate logistic regressions were used to investigate separately the extent of alternative tobacco product use in current cigarette smokers and in those who reported not smoking cigarettes controlling for demographic and other independent influences. The results indicate that for adolescent smokers and nonsmokers, the use of one type of alternative tobacco product made it much more likely the individual would use one or more of the other alternative tobacco products. Non-cigarette smokers using these tobacco products appeared to exhibit symptoms of nicotine dependence comparable to those of cigarette smokers. More information on adolescent use of alternative tobacco products is needed. Current cigarette use declined 3.4% annually over 2004-2009 for the NYTS 14- to 17-year-old population, but this cohort's use of alternative tobacco products was unchanged. The number of adolescents aged 14-17 who did not smoke cigarettes but used alternative tobacco products increased 5.9% per year over the same period. Current surveillance measures need to be expanded in order to gain a more comprehensive understanding of adolescent alternative tobacco use.
Factors Associated with American Indian Cigarette Smoking in Rural Settings
Hodge, Felicia; Nandy, Karabi
2011-01-01
Introduction: This paper reports on the prevalence, factors and patterns of cigarette smoking among rural California American Indian (AI) adults. Methods: Thirteen Indian health clinic registries formed the random household survey sampling frame (N = 457). Measures included socio-demographics, age at smoking initiation, intention to quit, smoking usage, smoking during pregnancy, health effects of smoking, suicide attempts or ideation, history of physical abuse, neglect and the role of the environment (smoking at home and at work). Statistical tests included Chi Square and Fisher’s Exact test, as well as multiple logistic regression analysis among never, former, and current smokers. Results: Findings confirm high smoking prevalence among male and female participants (44% and 37% respectively). American Indians begin smoking in early adolescence (age 14.7). Also, 65% of current smokers are less than 50% Indian blood and 76% of current smokers have no intention to quit smoking. Current and former smokers are statistically more likely to report having suicidal ideation than those who never smoked. Current smokers also report being neglected and physically abused in childhood and adolescence, are statistically more likely to smoke ½ pack or less (39% vs. 10% who smoke 1+ pack), smoke during pregnancy, and have others who smoke in the house compared with former and never smokers. Conclusion: Understanding the factors associated with smoking will help to bring about policy changes and more effective programs to address the problem of high smoking rates among American Indians.

Whether smokers and former smokers have worse lipid profiles or glucose levels than non-smokers remains unclear. The subjects were 1152 Japanese males aged 42 to 81 years. The subjects were divided according to their smoking habits (nonsmokers, former smokers, and current smokers) and their visceral fat area (VFA) (<100 cm(2) and ≥100 cm(2)). The serum triglyceride (TG) levels of 835 males were assessed. In the VFA ≥100 cm(2) group, a significantly greater proportion of current smokers (47.3%) exhibited TG levels of ≥150 mg/dL compared with former smokers (36.4%) and non-smokers (18.8%). The difference in TG level distribution between former smokers and non-smokers was also significant. However, among the subjects with VFA of <100 cm(2), the TG levels of the three smoking habit groups did not differ. The serum hemoglobin A1c (HbA1c) levels of 877 males were also assessed. In the VFA <100 cm(2) group, significantly higher proportions of current smokers (17.9%) and former smokers (14.9%) demonstrated HbA1c levels of ≥5.6% compared with non-smokers (6.3%). In contrast, in the VFA ≥100 cm(2) group, significantly fewer former smokers displayed HbA1c levels of ≥5.6% compared with non-smokers and current smokers. Furthermore, the interaction between smoking habits and VFA was associated with the subjects' TG and HbA1c concentrations, and the associations of TG and HbA1c concentrations and smoking habits varied according to VFA. Both smoking habits and VFA exhibited associations with TG and HbA1c concentrations. The associations between smoking habits and these parameters differed according to VFA.

Animal studies and human studies in small selected populations have shown a positive association between nicotine smoking and resting energy expenditure (REE), but data in large cohorts are lacking. We aimed to investigate the association between smoking behavior and REE in a large, population-based study. Population-based cross-sectional study. In this cross-sectional analysis of baseline measurements from the Netherlands Epidemiology of Obesity (NEO) study (n=6673), we included participants with REE measurement by indirect calorimetry who were not using lipid or glucose lowering drugs (n=1189). We used linear regression analysis to examine the association of smoking status (never, former, occasional, current smoker) and smoking quantity (pack years) with REE per kilogram (kg) fat free mass (FFM) and with REE adjusted for FFM. Models were adjusted for age, sex, ethnicity, educational level, physical activity, energy intake and body mass index (BMI). Mean (standard deviation, SD) age was 55.2 (5.9) years and BMI was 26.3 (4.4) kg/m(2). 60% of the participants were women. Mean (SD) REE/FFM (kcal/day/kg FFM) was for male never smokers 25.1 (2.0), male current smokers 26.4 (2.8), female never smokers 28.9 (2.5) and female current smokers 30.1 (3.7). After adjustment, only current smokers had a higher REE/FFM (mean difference 1.28, 95% CI 0.64, 1.92), and a higher REE adjusted for FFM (mean difference 60.3 kcal/day, 95% CI 29.1, 91.5), compared with never smokers. There was no association between pack years and REE/FFM (mean difference -0.01, 95% CI -0.06, 0.04) or REE adjusted for FFM (mean difference 0.2, 95% CI -2.4, 2.8) in current smokers. Current smoking is associated with a higher resting energy expenditure compared with never smoking in a large population-based cohort. Copyright © 2015 Elsevier Inc. All rights reserved.

Although beverage intake patterns have been shown to differ by smoking status, it is unknown whether the contributions of beverages to intakes of energy and MyPlate components also differ. The purpose of this study was to compare beverage intakes and contributions of energy and MyPlate components by source (food alone, beverages alone, and food and beverages together) in diets of adult current, former, and never smokers. Dietary data from 4,823 men and 4,672 women aged ≥20 years who participated in What We Eat in America, National Health and Nutrition Examination Survey 2005-2008, were analyzed. Beverage intake and the contributions to energy and MyPlate components by beverages. Regression analyses identified differences in intake among groups. Current smokers consumed more total beverages, coffee, and sugar-sweetened beverages than never and former smokers (P<0.001). Male current smokers drank more alcoholic beverages than never and former smokers, whereas female current and former smokers both consumed more alcoholic beverages than never smokers. Current smokers obtained more energy from beverages than their nonsmoking counterparts, although total energy intake did not differ. Intakes of added sugars, alcohol, and empty calories were higher for current than never smokers, and differences were accounted for by current smokers' beverage choices. This study adds to the body of research on smoking and dietary behavior by showing that not only do smokers consume a higher volume of beverages, but they also have a higher intake of energy provided by beverages, mainly empty calories from added sugars and alcohol. Our findings highlight the importance of assessing beverages' contribution to the total diet. Recognizing the common co-occurrence of smoking and specific beverage choices can help target health promotion and disease prevention efforts for this subpopulation.

Flavored and menthol tobacco products are particularly appealing to young adults. However, little is known about factors associated with their use in this population. To examine characteristics associated with using menthol cigarettes, flavored other tobacco products (OTP), and flavored e-cigarettes among young adults. Using a nationally representative online sample of young adults (n=4239) from the Truth Initiative Young Adult Cohort Study, mutually exclusive groups were created from the subset of current tobacco users (N=1037) for users of menthol cigarettes (N=311; 30%), non-menthol cigarettes (N=426; 41%), flavored OTP only users (N=114; 11%), and non-flavored OTP only users (N=186; 18%) to examine factors of being in any one group. Data were collected in July 2012. In the full multivariable model, significant correlates of current menthol cigarette use were female gender (AOR=2.08), Black race (AOR=5.31), other race (AOR=2.72), Hispanic ethnicity (AOR=2.46) and self-identifying as a smoker, social smoker, or occasional smoker (AOR=10.42). Significant correlates of current flavored OTP use were younger age (18-24; AOR=3.50), self-identifying as a smoker, social smoker, or occasional smoker (AOR=30) and generalized anxiety (AOR=0.30). This study highlights female gender, Blacks/other race/Hispanics, smokers, social smokers and sexual minorities as correlates of menthol cigarette use and younger age as a predictor of flavored OTP use. Restricting access to flavored tobacco products may be one intervention to help slow the tobacco epidemic, particularly among many of the most vulnerable groups-young women and racial and/or ethnic minorities.

Using a nationally representative sample of U.S. adults, the aims of this study were to examine the impact of early smoking initiation on the development of self-reported smoking-related morbidity and all-cause mortality. National Health Interview Survey data from 1997 through 2005 were linked to the National Death Index with follow-up to December 31, 2011. Two primary dependent variables were smoking-related morbidity and all-cause mortality; the primary independent variable was age of smoking initiation. The analyses included U.S. population of current and former smokers aged ≥30 years (N=90,278; population estimate, 73.4 million). The analysis relied on fitting logistic regression and Cox proportional hazards models. Among the U.S. population of smokers, 7.3% started smoking before age 13 years, 11.0% at ages 13-14 years, 24.2% at ages 15-16 years, 24.5% at ages 17-18 years, 14.5% at ages 19-20 years, and 18.5% at ages ≥21 years. Early smoking initiation before age 13 years was associated with increased risks for cardiovascular/metabolic (OR=1.67) and pulmonary (OR=1.79) diseases as well as smoking-related cancers (OR=2.1) among current smokers; the risks among former smokers were cardiovascular/metabolic (OR=1.38); pulmonary (OR=1.89); and cancers (OR=1.44). Elevated mortality was also related to early smoking initiation among both current (hazard ratio, 1.18) and former smokers (hazard ratio, 1.19). Early smoking initiation increases risks of experiencing smoking-related morbidities and all-cause mortality. These risks are independent of demographic characteristics, SES, health behaviors, and subsequent smoking intensity. Comprehensive tobacco control programs should be implemented to prevent smoking initiation and promote cessation among youth. Copyright © 2017 American Journal of Preventive Medicine.

This cross-sectional analysis provides up-to-date information about dietary patterns (DP) and their sociodemographic correlates in European elderly individuals. We studied 6686 enrollees aged 65+ (55% women) in the ongoing French population-based NutriNet-Santé e-cohort. Diet was assessed via three 24 h records. The sex-specific correlates of factor analysis derived DP were identified with multivariable linear regression. Using 22 pre-defined food groups, three DP were extracted. The "healthy" DP (fruit, vegetables, grains, nuts, fish) was positively associated with education, living alone, and being a former smoker (women), and negatively associated with being overweight, current smoker (men), age 75+ years, having hypertension, and obesity (women). The "western" DP (meat, appetizers, cheese, alcohol) was positively associated with BMI (men) and being a former/current smoker; it was negatively associated with age 75+ years (women) and living alone. The "traditional" DP (bread, potatoes, milk, vegetables, butter, stock) was positively associated with age and negatively associated with being a former/current smoker, education (men), and residing in an urban/semi-urban area. The findings support the diversity of DP among the elderly, highlighting sex-specific differences. The "healthy" DP explained the largest amount of variance in intake. Future studies could replicate the models in longitudinal and international contexts.

Background Colorectal cancer (CRC) is the third most common cancer in the USA. While various lifestyle factors have been shown to alter the risk for colorectal cancer, recommendations for the early detection of CRC are based only on age and family history. Methods This case-only study examined the age at diagnosis of colorectal cancer in subjects exposed to tobacco smoke. Subjects included all patients who attended RPCI between 1957 and 1997, diagnosed with colorectal cancer, and completed an epidemiologic questionnaire. Adjusted linear regression models were calculated for the various smoking exposures. Results Of the 3,540 cases of colorectal cancer, current smokers demonstrated the youngest age of CRC onset (never: 64.2 vs. current: 57.4, P < 0.001) compared to never smokers, followed by recent former smokers. Among never smokers, individuals with past second-hand smoke exposure were diagnosed at a significantly younger age compared to the unexposed. Conclusion This study found that individuals with heavy, long-term tobacco smoke exposure were significantly younger at the time of CRC diagnosis compared to lifelong never smokers. The implication of this finding is that screening for colorectal cancer, which is recommended to begin at age 50 years for persons at average risk should be initiated 5–10 years earlier for persons with a significant lifetime history of exposure to tobacco smoke.

To compare e-cigarette flavors preferred and reasons for use and discontinued use across never, current, and former e-cigarette users and cigarette smokers. We recruited 1567 participants aged 18-34 years through Facebook ads targeting tobacco users and nonusers in August 2014 to complete an online survey. We assessed tobacco use, preferred flavors, and reasons for e-cigarette use and discontinued use. Our sample was 49 % male, 87 % White; 56 % current cigarette smokers; and 53 % e-cigarette users. Current e-cigarette users used an average of 20.9 days in the past 30 (SD = 11.7) and 55.2 puffs/day (SD = 37.3). Compared to never and current smokers, former smokers used e-cigarettes more frequently (p's <0.001). Among users and nonusers, the most preferred was fruit flavors, and the most commonly reported reason for e-cigarette use was "they might be less harmful than cigarettes". The most endorsed reason for discontinued e-cigarette use was "using other tobacco products instead". Never, current, and former smokers had distinct reasons for e-cigarette use and discontinued use and differed in flavor preferences. Regulating marketing and flavors may impact e-cigarette uptake by young adults.

The inter-relationships between smoking habits and weight gain are complex. However, few studies have examined the association of smoking habits with weight gain over the life course. Major smoking parameters and weight gain over time were examined in a large cohort of postmenopausal women aged 50-79 years at enrollment between 1993 and 1998 (N=161,808) and followed through 2014 (analyses conducted in 2016). Cross-sectional analyses were used to assess the association of smoking and body weight at baseline. Retrospective data were used to correlate smoking status with body weight over a 45-year period prior to enrollment. In addition, the association of smoking with weight gain over 6 years of follow-up was examined. At baseline, women who had quit smoking prior to enrollment weighed 4.7 kg more than current smokers and 2.6 kg more than never smokers. Former, never, and current smokers all gained weight over the 45-year period from age 18 years to time of enrollment (average age, 63 years): 16.8, 16.4, and 14.6 kg, respectively. In prospective analyses, women who were current smokers at baseline but who quit smoking during follow-up gained more than 5 kg by Year 6 compared with current smokers at baseline who continued to smoke. Among long-term quitters, greater intensity of smoking and more recent quitting were associated with greater weight gain. These results suggest that excess weight gain associated with smoking cessation occurs soon after quitting and is modest relative to weight gain in never smokers over the adult lifespan.

Aims We evaluated coronary artery disease (CAD) extent, severity, and major adverse cardiac events (MACEs) in never, past, and current smokers undergoing coronary CT angiography (CCTA). Methods and results We evaluated 9456 patients (57.1 ± 12.3 years, 55.5% male) without known CAD (1588 current smokers; 2183 past smokers who quit ≥3 months before CCTA; and 5685 never smokers). By risk-adjusted Cox proportional-hazards models, we related smoking status to MACE (all-cause death or non-fatal myocardial infarction). We further performed 1:1:1 propensity matching for 1000 in each group evaluate event risk among individuals with similar age, gender, CAD risk factors, and symptom presentation. During a mean follow-up of 2.8 ± 1.9 years, 297 MACE occurred. Compared with never smokers, current and past smokers had greater atherosclerotic burden including extent of plaque defined as segments with any plaque (2.1 ± 2.8 vs. 2.6 ± 3.2 vs. 3.1 ± 3.3, P < 0.0001) and prevalence of obstructive CAD [1-vessel disease (VD): 10.6% vs. 14.9% vs. 15.2%, P < 0.001; 2-VD: 4.4% vs. 6.1% vs. 6.2%, P = 0.001; 3-VD: 3.1% vs. 5.2% vs. 4.3%, P < 0.001]. Compared with never smokers, current smokers experienced higher MACE risk [hazard ratio (HR) 1.9, 95% confidence interval (CI) 1.4–2.6, P < 0.001], while past smokers did not (HR 1.2, 95% CI 0.8–1.6, P = 0.35). Among matched individuals, current smokers had higher MACE risk (HR 2.6, 95% CI 1.6–4.2, P < 0.001), while past smokers did not (HR 1.3, 95% CI 0.7–2.4, P = 0.39). Similar findings were observed for risk of all-cause death. Conclusion Among patients without known CAD undergoing CCTA, current and past smokers had increased burden of atherosclerosis compared with never smokers; however, risk of MACE was heightened only in current smokers.

Limited knowledge exists examining the association between smoking status, symptom expression, and alcohol or illicit drug use. The goal of this study was to clarify these associations in patients with advanced cancer. We retrospectively reviewed 560 charts and identified 300 consecutive advanced cancer patients who completed a comprehensive smoking questionnaire. Data including the Edmonton Symptom Assessment System, Cut down/Annoyed/Guilty/Eye opener (CAGE) alcoholism screening questionnaire, illicit drug use history, and daily opioid requirements-morphine equivalent daily dose-were collected. Among 300 patients, 119 (40%) were never smokers, 148 (49%) former smokers, and 33 (11%) current smokers. The most common malignancies were gastrointestinal (28%) and lung (20%). Current smokers were more likely to be single (P < 0.01) and significantly younger than former smokers (P < 0.001) but did not differ in age from never smokers. Never smokers were more likely to be female (P < 0.001). Current smokers reported significantly higher pain expression than former and never smokers (median 7 vs. 5.5 vs. 5, respectively, P = 0.02), higher CAGE positivity (42% vs. 21% vs. 3%, P < 0.001) and were more likely to have a history of illicit drug use (33% vs. 16% vs. 3%, P < 0.001). The morphine equivalent daily dose was not significantly different according to smoking status. In advanced cancer, patients who were former or current smokers were significantly more likely to have a history of CAGE positivity and illicit drug use compared with never smokers. Current smokers expressed significantly higher pain. A smoking history may be a marker of an increased risk of opioid misuse. Published by Elsevier Inc.

Objective To assess the hazards at an early phase of the growing epidemic of deaths from tobacco in China. Design Smoking habits before 1980 (obtained from family or other informants) of 0.7 million adults who had died of neoplastic, respiratory, or vascular causes were compared with those of a reference group of 0.2 million who had died of other causes. Setting 24 urban and 74 rural areas of China. Subjects One million people who had died during 1986-8 and whose families could be interviewed. Main outcome measures Tobacco attributable mortality in middle or old age from neoplastic, respiratory, or vascular disease. Results Among male smokers aged 35-69 there was a 51% (SE 2) excess of neoplastic deaths, a 31% (2) excess of respiratory deaths, and a 15% (2) excess of vascular deaths. All three excesses were significant (P<0.0001). Among male smokers aged ⩾70 there was a 39% (3) excess of neoplastic deaths, a 54% (2) excess of respiratory deaths, and a 6% (2) excess of vascular deaths. Fewer women smoked, but those who did had tobacco attributable risks of lung cancer and respiratory disease about the same as men. For both sexes, the lung cancer rates at ages 35-69 were about three times as great in smokers as in non-smokers, but because the rates among non-smokers in different parts of China varied widely the absolute excesses of lung cancer in smokers also varied. Of all deaths attributed to tobacco, 45% were due to chronic obstructive pulmonary disease and 15% to lung cancer; oesophageal cancer, stomach cancer, liver cancer, tuberculosis, stroke, and ischaemic heart disease each caused 5-8%. Tobacco caused about 0.6 million Chinese deaths in 1990 (0.5 million men). This will rise to 0.8 million in 2000 (0.4 million at ages 35-69) or to more if the tobacco attributed fractions increase. Conclusions At current age specific death rates in smokers and non-smokers one in four smokers would be killed by tobacco, but as the epidemic grows this proportion will roughly double. If current smoking uptake rates persist in China (where about two thirds of men but few women become smokers) tobacco will kill about 100 million of the 0.3 billion males now aged 0-29, with half these deaths in middle age and half in old age. Key messagesOf the Chinese deaths now being caused by tobacco, 45% are from chronic lung disease, 15% from lung cancer, and 5-8% from each of oesophageal cancer, stomach cancer, liver cancer, stroke, ischaemic heart disease, and tuberculosisTobacco now causes 13% (and will probably eventually cause about 33%) of deaths in men but only 3% (and perhaps eventually about 1%) of deaths in women as the proportion of young women who smoke has become smallTwo thirds of men now become smokers before age 25; few give up, and about half of those who persist will be killed by tobacco in middle or old ageIf present smoking patterns continue about 100 million of the 0.3 billion Chinese males now aged 0-29 will eventually be killed by tobaccoTobacco caused 0.6 million deaths in 1990 and will cause at least 0.8 million in 2000 (0.7 million in men) and about 3 million a year by the middle of the century on the basis of current smoking patterns PMID:9822393

This study assessed the awareness and use of traditional and novel tobacco products and dual use of cigarettes with electronic nicotine delivery systems (ENDS) among USA adults. Data were obtained from the 2014 Tobacco Products and Risk Perceptions Survey of a probability sample of 5717 USA adults conducted June-November, 2014. Use of ENDS varied by demography and by cigarette and other tobacco use. Adults aged 25-34, non-heterosexual adults, and those reporting poorer health reported higher rates of current ENDS use. Current cigarette smokers had much greater odds of ENDS ever use than never smokers, with one-half of all cigarette smokers having used ENDS and 20.7 % currently using them. However, 22.0 % of current ENDS users were former cigarette smokers, and 10.0 % were never cigarette smokers. Patterns of ENDS use are evolving rapidly and merit continued surveillance. Nearly 10 % of adult ENDS usage is among never smokers. The public health challenge is how to enhance the potential that ENDS can replace combusted tobacco products without expanding nicotine use among youth, long-term ex-smokers, and other vulnerable populations.

We compare life course characteristics of a cohort of African American women (N=457) by their smoking status at age 42: never smoker (34.1%), former smoker (27.8%), or current smoker (38.1%). The Woodlawn population from which our sample is drawn has been followed from first grade (1966-67) to mid adulthood (2002-3) and is a cohort of children from a disadvantaged Chicago community. Examination of the effects of cumulative disadvantage on smoking behavior showed that nearly half of women who first lived in poverty as children, dropped out of school, became teen mothers, and were poor as young adults currently smoked; less than 22% of women with none of these difficulties were current smokers. Regression analyses focusing on smoking and evidence of social disadvantage in childhood, adolescence, and young adulthood showed that women with more education were much less likely to be current smokers. Women reporting low parental supervision in adolescence and less frequent church attendance in young adulthood and those whose mothers' reported regular smoking were significantly more likely to be current smokers. Poverty and marital status in young adulthood varied significantly among smoking categories in bivariate relationships, but not in final multivariate regression models. Few other studies have examined smoking careers with data from age 6-42, comparing social disadvantage characteristics over the life course. While marital status, church involvement and parental supervision are not usually included as measures of socioeconomic status, they represent advantages in terms of social capital and should be considered mechanisms for transmitting disparities.

Psychosocial stress is a significant risk factor for smoking, and Blacks experience higher levels of psychosocial stress relative to other racial/ethnic groups. Limited research has comprehensively examined psychosocial stressors in relation to smoking among Blacks. We examined psychosocial stressors in relation to smoking status (current, previous, and never) in middle-aged Blacks (34-85 years, n = 592) from Milwaukee, Wisconsin, a subset of the Midlife in the United States Study II (2004-2006). Eleven stressor domains were assessed, including psychological and physical work stress, work-family conflict, perceived inequality, relationship stress, neighborhood stress, discrimination, financial stress, recent problems, stressful events, and childhood adversity. We also calculated a cumulative score. Multinomial models were adjusted for age, gender, education, and income. Seven of the 11 stressors and the cumulative score were associated with higher odds of being a current smoker compared with a never-smoker: neighborhood, financial, relationship, and psychological work stress, perceived inequality, stressful events, childhood adversity (p values <.05; ORs ranged from 1.28 to 1.77). Three stressors and the cumulative score were associated with higher odds of being a previous smoker versus a never-smoker (p < .05). Individuals who scored in the top quartile on 5 or more stressors were 3.74 (95% CI = 2.09-6.71) times as likely to be current smokers, and more than twice as likely to be previous smokers, compared with individuals with no high stressors. These results demonstrate a strong relationship between stress and smoking among urban middle-aged Blacks and suggest that cessation programs should address modifiable individual and community-level stressors.

Smoking has been associated with an important health risk. The aim was to analyze the health-related quality of life (HRQoL) status of the adult Spanish general population included in the National Health Survey according to its smoking status. Data were included from National Health Survey for the year 2011-2012 with information of HRQoL status in general population over 15 years of age. Adult male and female, 18 years of age or above, were categorized into 3 exclusive groups according to their current smoking status: smokers (daily smokers of any form of tobacco, at least the previous 12 months), ex-smokers of one or more years since quitting smoking and people who have never smoked (non smokers). HRQoL was assessed with the Spanish version of the EQ-5D-5L questionnaire included into the National Health Survey. A total of 19,604 records were analyzed: 4,723 (24.09%) smokers, 3,797 (19.37%) ex-smokers, and 11,084 (56.54%) non smokers, male and female with 18 years of age or above. Smokers showed significantly adjusted mean scores (95% CI) in utility of 0.903 (0.899-0.908) and 75.36 (74.06-76.69) in the visual analogue scale of current state of health, ex-smokers 0.924 (0.919-0.929) and 76.85 (76.67-78.07), and non smokers 0.902 (0.899-0.905) and 76.25 (75.02-77.51), P<.01 between groups in both variables. In the Spanish general population, subjects who are ex-smokers showed better utility values and state health scores, supporting the hypothesis that quitting smoking could be associated with a discreet improvement of HRQoL.

Studies investigating whether smoking increases or decreases during economic downturn provided contrasting results. For the first time, we used direct questions to analyse changes in smoking behaviour due to the 2008 financial crisis, comparing socio-economic characteristics of smokers who changed with those who kept their smoking intensity. Cross-sectional survey. We used data from three annual surveys conducted in Italy in 2012-2014 on representative samples of the Italian general population aged ≥15 years. A total of 1919 current smokers were asked specific questions on the influence of the economic crisis that started in 2008 on their smoking behaviour. Overall, 77.4% of 1919 current smokers reported not to have changed their smoking behaviour, 19.1% to have reduced, and 3.5% to have increased their smoking intensity as a consequence of the economic crisis. The reduction in cigarette smoking increased with age: compared to the respondents aged <25 years, the multivariate odds ratio (OR) for those aged 25-44, 45-64 and ≥65 years were 0.65, 0.46 and 0.33, respectively (P for trend<0.001). Reduction was significantly lower among intermediate (OR = 0.68 compared to low) and high education levels (OR = 0.28; P for trend<0.001). A significant inverse trend for increasing consumption was observed with age (P = 0.022), education (P = 0.003) and family income (P < 0.001). The large majority of current smokers did not change their smoking habit following the economic crisis. However, there are specific vulnerable subgroups of smokers, constituted by the young and subjects with low socio-economic status, that were reactive to the global economic crisis. These groups are more prone to change their smoking behaviours, either for better or -, in a smaller proportion -, for worse. Copyright © 2015 The Royal Society for Public Health.

OBJECTIVE: To examine the relation between smoking status, clinical need, and likelihood of coronary artery bypass grafting in middle aged men. DESIGN: A prospective study of cardiovascular disease in British men aged 40 to 59 years, screened in 1978-80 and followed until December 1991. SUBJECTS AND SETTING: 7735 men drawn from one general practice in each of 24 British towns. MAIN OUTCOME MEASURE: Coronary artery bypass graft surgery. RESULTS: Of the 3185 current smokers, 38 (1.03/1000/year) underwent coronary artery bypass surgery compared with 47 of 2715 (1.45/1000/year) ex-smokers, and 19 of 1817 (0.85/1000/year) never-smokers. Ex-smokers had a lower incidence of major ischaemic heart disease during follow up than current smokers. After adjustment for incidence of ischaemic heart disease during follow up, the hazard ratio of coronary artery bypass surgery for ex-smokers compared with smokers was 1.52 (95% confidence interval 0.99 to 2.34). Ex-smokers were more likely at screening to recall a doctor diagnosis of ischaemic heart disease than smokers (7.1% v 5.3%), but among those who recalled a doctor diagnosis, smokers were less likely to undergo coronary artery bypass surgery than ex-smokers (9.4% v 3.5%, P = 0.026). By 1992, men defined as smokers at screening were no less likely than ex-smokers to have been referred to a cardiologist (18.5% v 18.8%), nor to report having undergone coronary angiography less frequently than ex-smokers (12.7% v 11.4%). CONCLUSION: Even allowing for the strong relation between coronary artery bypass surgery and clinical need, continuing smokers were less likely to undergo coronary artery bypass surgery than ex-smokers. A complex interplay exists between the men's experience of heart disease, the decision to stop smoking, and the willingness of doctors to consider coronary artery bypass surgery. PMID:8697156

Previous studies have shown that smokers presented with ST-segment elevation myocardial infarction (STEMI) a decade earlier than non-smokers. However, no account has been made for population smoking trends, an important deficit addressed by this study. The combination of admission data on patients with acute STEMI undergoing percutaneous coronary intervention and demographic data supplied by the Office for National Statistics for the South Yorkshire population between 2009-2012 were analysed to generate incidence rates and rate ratios (RR) to quantify the relative risk of STEMI from smoking, overall and by age group. There were 1795 STEMI patients included of which 72.9% were male. 68 patients were excluded as they had no smoking status recorded, leaving 48.5% of the remaining population as current smokers, 27.2% ex-smokers and 24.3% never smokers. Smokers were over-represented with overall smoking prevalence in South Yorkshire calculated at 22.4%. The incidence of STEMI in smokers aged under 50, 50-65 and over 65 years was 59.7, 316.9 and 331.0 per 100 000 patient years at risk compared to 7.0, 60.9 and 106.8 for the combined group of ex- and never smokers. This gave smokers under the age of 50 years an 8.47 (95% CI 6.80 to 10.54) increase in rate compared to non-smokers of the same age, with the 50-65 and over 65 age groups having RRs of 5.20 (95% CI 4.76 to 5.69) and 3.10 (95% CI 2.67 to 3.60), respectively. Smoking was associated with an eightfold increased risk of acute STEMI in younger smokers, when compared to ex- and never smokers. Further efforts to reduce smoking in the youngest are needed.

Background Previous studies indicate that smoking affects the outcome of some infections and is a risk factor for Puumala virus (PUUV) infection. The aim of this study was to assess the effect of smoking on the clinical severity of PUUV infection and the prevalence of smoking in patients with PUUV infection. Methods A questionnaire on smoking habits was sent to 494 patients in 2012, who had been treated in Tampere University Hospital, Finland, for serologically confirmed PUUV infection during years 1982–2012. Results Of all patients, 357 (72%) participated. Maximum plasma creatinine level measured during acute illness was significantly higher in current smokers than in non-smokers (median: 273 versus 184 µmol/L, P < 0.001). Current smokers had a higher maximum blood leucocyte count than non-smokers (median: 10.8 versus 8.9 × 109/L, P < 0.001) and they were younger than non-smokers (38 versus 45 years, P < 0.001). There were no differences between current smokers and non-smokers in the other variables reflecting the severity of PUUV infection. Altogether 51% were current smokers at the time of onset of the illness, 57% of males and 36% of females. During these years in Finland, smoking among males in the same aged population has decreased from 33 to 22% and among females, smoking has varied between 14 and 20%. Conclusions Smoking is common in patients with PUUV infection. Current smokers suffer from more severe acute kidney injury (AKI) and they have higher leucocyte count than non-smokers in PUUV infection. Smoking cessation decreases the risk of severe AKI to the same level as observed in never-smokers. PMID:26150428

Background Tobacco smoking is a major contributor to the public health burden and healthcare costs worldwide, but the determinants of smoking behaviours are poorly understood. We conducted a large individual-participant meta-analysis to examine the extent to which work-related stress, operationalised as job strain, is associated with tobacco smoking in working adults. Methodology and Principal Findings We analysed cross-sectional data from 15 European studies comprising 166 130 participants. Longitudinal data from six studies were used. Job strain and smoking were self-reported. Smoking was harmonised into three categories never, ex- and current. We modelled the cross-sectional associations using logistic regression and the results pooled in random effects meta-analyses. Mixed effects logistic regression was used to examine longitudinal associations. Of the 166 130 participants, 17% reported job strain, 42% were never smokers, 33% ex-smokers and 25% current smokers. In the analyses of the cross-sectional data, current smokers had higher odds of job strain than never-smokers (age, sex and socioeconomic position-adjusted odds ratio: 1.11, 95% confidence interval: 1.03, 1.18). Current smokers with job strain smoked, on average, three cigarettes per week more than current smokers without job strain. In the analyses of longitudinal data (1 to 9 years of follow-up), there was no clear evidence for longitudinal associations between job strain and taking up or quitting smoking. Conclusions Our findings show that smokers are slightly more likely than non-smokers to report work-related stress. In addition, smokers who reported work stress smoked, on average, slightly more cigarettes than stress-free smokers. PMID:22792154

Background Several Western studies have revealed that among non-diabetics, glycosylated hemoglobin A1c (HbA1c) levels are higher in smokers than non-smokers. While studies conducted in Western populations consistently support this association, a recent meta-analysis reported that studies carried out in non-Western populations, including studies of Chinese, Egyptian, and Japanese-Americans, did not detect any significant differences in HbA1c levels between smokers and non-smokers. Objectives We assessed the association between smoking habits and HbA1c levels in the general Korean adult population using data from the Korean National Health and Nutrition Examination Survey (KNHANES) performed in 2011–2012. Methods A total of 10,241 participants (weighted n=33,946,561 including 16,769,320 men and 17,177,241 women) without diabetes were divided into four categories according to their smoking habits: never smokers (unweighted n/ weighted n= 6,349/19,105,564), ex-smokers (unweighted n/ weighted n= 1,912/6,207,144), current light smokers (<15 cigarettes per day, unweighted n/ weighted n=1,205/5,130,073), and current heavy smokers (≥15 cigarettes per day, unweighted n/ weighted n=775/3,503,781). Results In age- and gender-adjusted comparisons, the HbA1c levels of each group were 5.52 ± 0.01% in non-smokers, 5.49 ± 0.01% in ex-smokers, 5.53 ± 0.01% in light smokers, and 5.61 ± 0.02% in heavy smokers. HbA1c levels were significantly higher in light smokers than in ex-smokers (p = 0.033), and in heavy smokers compared with light smokers (p < 0.001). The significant differences remained after adjusting for age, gender, fasting plasma glucose, heavy alcohol drinking, hematocrit, college graduation, and waist circumference. Linear regression analyses for HbA1c using the above-mentioned variables as covariates revealed that a significant association between current smoking and HbA1c (coefficient 0.021, 95% CI 0.003–0.039, p = 0.019). Conclusions Current smoking was independently associated with higher HbA1c levels in a cigarette exposure-dependent manner in a representative population of Korean non-diabetic adults. In this study, we have observed an association between smoking status and HbA1c levels in non-diabetics drawn from a non-Western population, consistent with previous findings in Western populations.

Inconsistent evidence supports better outcome in smokers after stroke. Our study examines this association in a large sample of ischemic stroke treated with intravenous thrombolysis. Virtual International Stroke Trials Archive (VISTA) database, composed of individual patient data of multiple clinical trials, was queried. The primary outcome was functional independence at 3 months noted by modified Rankin Scale (mRS; a 7-point scale ranging from 0 [no deficit] to 6 [death]) score≤ 2. The secondary outcomes were National Institutes of Health Stroke Scale (NIHSS; stroke severity measure, ranging from 0 [no deficit] to 42 [most severe]) score at 24 hours and the occurrence of symptomatic intractracranial hemorrhage. A total of 5383 patients were included: 1501 current smokers and 3882 nonsmokers. Smokers were younger (60 ± 13 vs. 71 ± 12 years, p < .0001) and had lower median NIHSS score at baseline (12 [8-17] vs. 13 [9-18], p < .0001). The rate of favorable functional outcome (mRS ≤ 2) at 3 months was significantly higher among current smokers (49.7% vs. 39.5%, p < .0001) and with crude ORs of 1.52, 95% CI 1.33-1.72. The association became non-significant after adjusting for age (OR 1.11, 95% CI 0.97-1.27). Subgroup analysis by age/gender strata showed that current smoking was associated with favorable outcome only in women ≥ 65 years. Current smoking was also associated with lower rates of symptomatic intracranial hemorrhage (adjusted OR 0.55, 95% CI 0.39-0.79). Smokers experience their first ever stroke 11 years younger than nonsmokers. This age difference explains the association between current smoking and favorable functional outcome. Smoking is associated with occurrence of first ever stroke at a younger age, therefore, focus should be on smoking prevention and treatment. The decision to treat ischemic stroke patients with intravenous thrombolysis should not be influenced by the patients' smoking status. © The Author 2017.

To examines smoking status, substance use, sociodemographics, and psychosocial characteristics in relation to alternative tobacco use among college students. Current tobacco use (cigarettes, cigar-like products, hookah, chew, snus) and correlates (sociodemographics, sensation-seeking, attitudes toward tobacco and smokers, social factors) were assessed among students aged 18-25 at 6 Southeastern US colleges using an online survey. Those who were younger, male, black, cigarette and marijuana users, and demonstrating at-risk psychosocial factors were at increased risk of alternative tobacco product use (p < .001). Among current smokers, never daily nondaily smokers were 3 times as likely as former daily non-daily smokers and daily smokers to use alternative tobacco products (p < .001). Important risk factors for alternative tobacco use included important sociodemographic and psychosocial characteristics.

Background Whether smokers and former smokers have worse lipid profiles or glucose levels than non-smokers remains unclear. Methods The subjects were 1152 Japanese males aged 42 to 81 years. The subjects were divided according to their smoking habits (nonsmokers, former smokers, and current smokers) and their visceral fat area (VFA) (<100 cm2 and ≥100 cm2). Results The serum triglyceride (TG) levels of 835 males were assessed. In the VFA ≥100 cm2 group, a significantly greater proportion of current smokers (47.3%) exhibited TG levels of ≥150 mg/dL compared with former smokers (36.4%) and non-smokers (18.8%). The difference in TG level distribution between former smokers and non-smokers was also significant. However, among the subjects with VFA of <100 cm2, the TG levels of the three smoking habit groups did not differ. The serum hemoglobin A1c (HbA1c) levels of 877 males were also assessed. In the VFA <100 cm2 group, significantly higher proportions of current smokers (17.9%) and former smokers (14.9%) demonstrated HbA1c levels of ≥5.6% compared with non-smokers (6.3%). In contrast, in the VFA ≥100 cm2 group, significantly fewer former smokers displayed HbA1c levels of ≥5.6% compared with non-smokers and current smokers. Furthermore, the interaction between smoking habits and VFA was associated with the subjects’ TG and HbA1c concentrations, and the associations of TG and HbA1c concentrations and smoking habits varied according to VFA. Conclusions Both smoking habits and VFA exhibited associations with TG and HbA1c concentrations. The associations between smoking habits and these parameters differed according to VFA. PMID:26616395

The present study examined change in use of various smoked and smokeless non-cigarette alternative products in a sample of college students, stratified by current, or past 30-day, cigarette smoking status. Participants were 698 students from seven four-year colleges in Texas. Participants completed two waves of online surveys regarding tobacco use, knowledge, and attitudes, with 14 months between each wave. The most prevalent products used by the entire sample at Wave 1 were cigarettes, followed by hookah, cigars/cigarillos/little cigars, and electronic cigarettes (e-cigarettes). At Wave 2, prevalence of e-cigarette use surpassed use of cigars/cigarillos/little cigars. Snus and chew/snuff/dip were relatively uncommon at both waves. Examination of change in use indicated that e-cigarette use increased across time among both current cigarette smokers and non-cigarette smokers. Prevalence of current e-cigarette use doubled across the 14-month period to 25% among current smokers and tripled to 3% among non-cigarette smokers. Hookah use also increased across time, but only among non-cigarette smokers, whereas it decreased among current cigarette smokers. Use of all other non-cigarette alternatives remained unchanged across time. Logistic regression analysis was used to examine the socio-demographic predictors of Wave 2 e-cigarette use, the only product that increased in use among both current cigarette smokers and non-cigarette smokers. Results indicated that Wave 1 current cigarette use and Wave 1 current e-cigarette use, but not gender, age, or race/ethnicity, were significantly associated with Wave 2 e-cigarette use. Findings underscore the need to track changes in the use of non-cigarette alternatives and call for additional research examining the factors contributing to change in use.

To examine the relationship between smoking, smoking cessation, and disease characteristics and quality of life (QoL) in spondyloarthritis. The Scotland Registry for Ankylosing Spondylitis collects data from clinically diagnosed patients with spondyloarthritis. Clinical data, including Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI) scores, were obtained from medical records. Mailed questionnaires contained information on smoking status and QoL (Ankylosing Spondylitis QoL questionnaire [ASQoL]). Linear and logistic regression were used to quantify the effect of smoking, and smoking cessation, on various disease-specific and QoL outcomes, with adjustments for age, sex, deprivation, education level, and alcohol use. Results are presented as regression coefficients (β) or odds ratios (ORs) with 95% confidence intervals (95% CIs). Data were obtained from 946 participants (73.5% male, mean age 52 years). Current smoking was reported by 22%, and 38% were ex-smokers. Ever smokers had poorer BASDAI (β = 0.5 [95% CI 0.2, 0.9]) and BASFI scores (β = 0.8 [95% CI 0.4, 1.2]), and reported worse QoL (ASQoL β = 1.5 [95% CI 0.7, 2.3]). Compared to current smokers, ex-smokers reported less disease activity (BASDAI β = -0.5 [95% CI -1.0, -0.04]) and significantly better QoL (ASQoL β = -1.2 [95% CI -2.3, -0.2]). They also were more likely to have a history of uveitis (OR 2.4 [95% CI 1.5, 3.8]). Smokers with spondyloarthritis experience worse disease than those who are never smokers. However, this study provides new evidence that, among smokers, smoking cessation is associated with lower disease activity and better physical function and QoL. Clinicians should specifically promote smoking cessation as an adjunct to usual therapy in patients with spondyloarthritis. © 2016, American College of Rheumatology.

Whether reduced activity level and exercise intolerance precede the clinical diagnosis of cardiopulmonary disorders in smokers is not known. We examined activity level and exercise test outcomes in a young population-based sample without overt cardiopulmonary disease, differentiating by smoking history. This was a multiyear cross-sectional study using United States National Health and Nutrition Examination Survey data from 1999-2004. Self-reported activity level and incremental exercise treadmill testing were obtained on survey participants ages 20-49 years, excluding individuals with cardio-pulmonary disease. Three thousand seven hundred and one individuals completed exercise testing. Compared to never smokers, current smokers with >10 pack years reported significantly higher odds of little or no recreation, sport, or physical activity (adjusted OR 1.62; 95% CI 1.12-2.35). Mean perceived exertion ratings (Borg 6-20) at an estimated standardized workload were significantly greater among current smokers (18.3-18.6) compared to never (17.3) and former smokers (17.9) (p<0.05). There were no significant differences in the proportions of individuals across estimated peak oxygen uptake categories among the groups after adjusting for age and sex. Among former smokers, increasing duration of smoking abstinence was associated with significantly lower likelihood of low estimated peak oxygen uptake categorization (p<0.05). Among young individuals without overt cardiopulmonary disease, current smokers had reduced daily activity and higher perceived exertion ratings. Besides supporting early smoking cessation, these results set the stage for future studies that examine mechanisms of activity restriction in young smokers and the utility of measures of activity restriction in the earlier diagnosis of smoking-related diseases.

To determine the prevalence and characteristics of current cigarette smokers who report receiving health care provider interventions ('5A's': ask, advise, assess, assist, arrange) for smoking cessation. Data came from the 2009-2010 National Adult Tobacco Survey, a telephone survey of United States adults aged ≥ 18 years. Among current cigarette smokers who reported visiting a health professional in the past year (n=16,542), estimates were calculated overall and by sex, age, race/ethnicity, education, income, health insurance coverage, and sexual orientation. Among smokers who visited a health professional (75.2%), 87.9% were asked if they used tobacco, 65.8% were advised to quit, and 42.6% were asked if they wanted to quit. Among those wanting to quit, 78.2% were offered assistance and 17.5% had follow-up arranged. Receipt of the 'ask' component was lower among males and uninsured individuals. Receipt of the 'advise' and 'assess' components was lower among those aged 18-24 and uninsured individuals. Receipt of the 'assist' component was lower among non-Hispanic blacks. No differences were observed for the 'arrange' component. Many current smokers report receiving health care provider interventions for smoking cessation. Continued efforts to educate, encourage, and support all health professionals to provide effective, comprehensive tobacco cessation interventions to their patients may be beneficial. © 2013.
Sociodemographic differences in triggers to quit smoking: findings from a national survey.
Vangeli, E; West, R
2008-12-01
Reasons for quitting smoking and triggers that finally precipitate a quit attempt are not necessarily the same thing. We sought to assess variation in reported triggers of attempts to stop smoking as a function of age, gender and socioeconomic status. Cross-sectional household survey in England. A total of 2441 smokers and ex-smokers aged 16 and over, who reported making at least one serious quit attempt in the last 12 months, were recruited. The main outcome measure was participants' responses to the question "What finally triggered your most recent quit attempt?". Respondents selected from a list of options or specified a trigger not on the list. In the event, smokers typically reported as triggers similar factors as have previously been reported as "reasons". "A concern about future health problems" (28.5%) was the most commonly cited trigger followed by "health problems I had at the time" (18%) and then "a decision that smoking was too expensive" (12.2%). The most common external trigger was advice from a health professional (5.6%). Future health concern was more common in smokers with higher socioeconomic status (SES), whereas cost and current health problems were more often cited by lower SES smokers. Younger smokers were more likely to report their quit attempt being triggered by a TV advertisement while older smokers were more likely to cite advice from a health professional. Concern about future health problems was cited less often by 16 to 24 year olds and those aged 65+ than those aged 25 to 64 years. There are significant differences in reported triggers for quit attempts as a function of sociodemographic factors. Most notably, smokers with higher SES are more likely to report concern about future health whereas those from lower SES are more likely to cite cost and current health problems.

The aim of this present investigation was to evaluate the clinicopathologic characteristics, oncogenic drivers, and prognosis of former smokers with non-small-cell lung cancer (NSCLC), and to compare them with those of the current and never smokers. This investigation was a single-institution retrospective study of 2289 NSCLC patients, who were classified as former, current, or never smokers. A collection was made of the clinicopathological characteristics, spectra of well-identified driver genes and survival rates. The survival rates were compared using log-rank test, and independent prognostic factors, identified using Cox regression analysis. Of 2289 NSCLC patients, 257 (11.2%) were former smokers; 868 (37.9%), current smokers; and 1164 (50.9%), never smokers. Compared with the current, the former were characterized by older age at diagnosis (64.3y vs. 59.9y; P < 0.001), earlier TNM stage (stage I, 47.9% vs. 39.5%; P = 0.017), fewer solid predominance in adenocarcinomas (16.2% vs. 29.5%; P = 0.005), and more EGFR mutation (33.2% vs. 20.7%; P < 0.001) but less KRAS mutation (6.7% vs. 11.9%, P = 0.041). No statistically significant survival differences were observed between the former and current. However, the light former smokers presented favorable overall survival when compared with the light current and heavy former or current (the light former vs. the heavy former, P = 0.028; the light former vs. the light current, P = 0.048; and the light former vs. the heavy current, P = 0.048). Our findings suggest that the former smokers with NSCLCs can have distinctive clinicopathologic characteristics, oncogenic drivers, and prognosis, and they, especially the light former, can benefit from smoking cessation. © 2016 The Authors.

The current study examined prevalence and correlates of electronic cigarette (e-cigarette) use in the Canadian population, using data from the nationally representative 2013 Canadian Tobacco, Alcohol and Drugs Survey (n=14,565). Sociodemographic correlates of e-cigarette use (ever, and in the past 30 days) were examined using logistic regression models. Overall, 8.5% of Canadians aged 15 and older reported having ever tried an e-cigarette; 1.8% had used one in the past 30 days. E-cigarette use was particularly high among smokers and young people. Overall, prevalence did not differ between males and females, for ever (P=0.24) or past 30-day use (P=0.30). Smoking status was the strongest correlate of e-cigarette use (ever and in the past 30 days, P<0.0001): 37.3% of current smokers had ever tried an e-cigarette (9.6% used in the past 30 days), compared to 3.0% of never-smokers (0.3% past 30-days), and 5.1% of former smokers (0.9% past 30-day). E-cigarette use also varied by age (P<0.0001): prevalence was highest among youth aged 15-19 (19.8% ever; 2.6% past 30-day) and young adults aged 20-24 (20.1% ever; 3.9% past 30-day), and decreased with age. Among youth, the majority of e-cigarette users were never-smokers, while the majority of adult users were smokers. In Canada, e-cigarette use is particularly high among smokers and young people. Dual use with cigarettes was common, with most e-cigarette users also smoking conventional cigarettes. Continued monitoring of e-cigarette use and its relationship with smoking should be a priority, given the rapidly-evolving e-cigarette market and implementation of new policy measures.

To test the hypothesis that cigarette smoking is associated with hot flushes through a mechanism involving androgen levels, progesterone levels, sex hormone-binding globulin levels, or the ratio of androgens to estrogens. Women with and without hot flushes were recruited from Baltimore, Maryland, and the surrounding counties. Women were between 45 and 54 years of age, with at least three menstrual periods in the previous 12 months, and were not postmenopausal. Study participants completed a questionnaire and gave a blood sample for hormone measurements. Current smokers had significantly higher androstenedione levels and a higher androgen-to-estrogen ratio than never smokers. Current smokers had significantly lower progesterone levels compared with never smokers. Former and current cigarette smokers had increased odds of experiencing hot flushes compared with never smokers (former: odds ratio [OR] 1.41, 95% confidence interval [CI] 0.99-2.01; current: OR 2.43, 95% CI 1.28-4.62). This association, however, was not attenuated by the addition of hormones to the smoking and hot-flush model. Cigarette smoking is associated with hot flushes through a mechanism that may not involve alterations in hormone levels or their ratios. II.

Smoking and obesity might alter the risk of sarcoidosis. However, the data remained inconclusive. A cohort of Olmsted County, Minnesota residents diagnosed with sarcoidosis between January 1, 1976 and December 31, 2013 was identified based on individual medical record review. For each sarcoidosis subject, one sex and aged-matched control without sarcoidosis was randomly selected from the same underlying population. Medical records of cases and controls were reviewed for smoking status at index date and body mass index (BMI) within 1 year before to 3 months after index date. 345 incident cases of sarcoidosis and 345 controls were identified. The odds ratio of sarcoidosis comparing current smokers with never smokers adjusted for age and sex was 0.34 (95% confidence interval (CI), 0.23-0.50). The odds ratio of sarcoidosis comparing current smokers with never smokers and former smokers adjusted for age and sex was 0.38 (95% CI, 0.26-0.56). The odds ratio of sarcoidosis comparing overweight subjects (BMI ≥ 25 kg/m 2 but < 30 kg/m 2 ) with subjects with normal/low BMI was 1.12 (95% CI, 0.72-1.75). The odds ratio of sarcoidosis comparing obese subjects (BMI ≥ 30 kg/m 2 ) with subjects with normal/low BMI was 2.54 (95% CI, 1.58-4.06). The odds ratio of sarcoidosis comparing obese subjects with non-obese subjects was 2.38 (95% CI, 1.60-3.56). In this population, current smokers have a lower risk of developing sarcoidosis while subjects with obesity have a higher risk of developing sarcoidosis. Copyright © 2016 Elsevier Ltd.

Cigarette smoking is a major source of oxidative stress. Protein carbonyls have been used as a biomarker of oxidative stress because of the relative stability of carbonylated proteins and the high protein concentration in blood. Increased levels of carbonyl groups have been found in serum proteins of smokers compared to nonsmokers. However, neither the dose effect of current cigarette smoke nor other predictors of oxidative stress have been studied. Hence, we used an ELISA (Enzyme-Linked Immunosorbent Assay) to evaluate plasma protein carbonyls in smokers recruited in the Early Lung Cancer Action Project (ELCAP) program. The lung cancer screening program enrolled current and former smokers age 60 years and over without a prior cancer diagnosis. A total of 542 participants (282 men and 260 women) completed a baseline questionnaire and provided blood samples for the biomarker study. Protein oxidation was measured by derivatization of the carbonyl groups with 2,4-dinitrophenylhydrazine (DNPH) and ELISA quantitation of the DNPH group. Current smoking status was confirmed with urinary cotinine. The mean (± SD) protein carbonyl level was 17.9 ± 2.9 nmol carbonyls/ml plasma. Protein carbonyls did not differ significantly by gender. Carbonyl levels were higher among current than former smokers, but these differences did not attain statistical significance, nor did differences by urine cotinine levels, pack-years, pack/day among current smokers, and smoking duration. In a multiple regression analysis, higher protein carbonyl levels were independently associated with increasing age (0.59 nmol/ml increase per 10 years, 95% CI 0.14, 1.05, p = 0.01), African-American vs. white race/ethnicity, (1.30 nmol/ml, 95% CI 0.4, 2.19, p =0.008), and lower educational attainment (0.75 nmol/ml, 95% CI 0.12, 1.38, p = 0.02). Although we found no significant difference between current versus past cigarette smoking and protein carbonyls in this older group of smokers, associations were found for age, ethnicity and educational attainment. Our results indicate that the measurement of plasma carbonyls by this ELISA technique is still an easy and suitable method for studies of diseases related to oxidative stress. PMID:17996865

Epidemiological and clinical studies have found a significant association between smoking and suicidal behaviour. 334 outpatients with DSM-IV diagnosis of unipolar major depression, bipolar (I+II) disorder, schizophrenia, schizoaffective disorder and pure panic disorder were interviewed regarding to their smoking habits and previous suicide attempts. With the exception of panic disorder patients, the rate of prior suicide attempt(s) was much higher among current and lifetime smokers than among never smokers in all diagnostic groups, but the difference was statistically significant only for lifetime smoker unipolar depressives and for current and lifetime smoker schizophrenics. Age, social class and alcohol/caffeine consumption was not controlled and dependent vs nondependent smokers were not distinguished. The findings support previous results on the strong relationship between smoking and suicidal behaviour in psychiatric (particularly major depressive and schizophrenic) patients.

Smoking is usually initiated early in life and most adult regular smokers have started smoking before 18 years of age. A younger age at smoking initiation is associated with risk taking behaviours and worse health outcomes regarding psychological and somatic conditions, suggested to be caused by exposure during critical developmental periods. The present study aims to investigate self-rated health among second grade high school boys and girls related to age at smoking initiation (<14 years of age and ≥ 14 years of age) among current and former smokers, compared to never smokers. Data was derived from the Scania public health survey among children and adolescents in 2012. The study was cross-sectional with retrospective information about first time cigarette smoking experiences among 3245 boys and 3434 girls in second grade of high school. Self-rated health was assessed with the question "How do you rate your general health". Associations of age at smoking initiation, current smoking status and poor self-rated health were investigated with logistic regression models. Crude odds ratios of poor self-rated health were increased for all smoking groups compared to never smokers. Former smoking boys and currently smoking girls with early smoking initiation had the highest odds ratios of poor self-rated health, with odds ratios (OR) 2.4 (95 % confidence interval (CI): 1.5-3.7) and OR 2.9 (95 % CI: 2.3-3.6), respectively. After adjustments for sociodemographic factors, health-related behaviours, psychosocial factors, weight and functional disabilities, the results were attenuated, but remained statistically significant regarding former and current smoking boys with early smoking initiation, OR 2.0 (95 % CI: 1.1-3.7) and OR 1.7 (95 % CI: 1.1-2.4) and for current smoking girls with early and later smoking initiation, OR 2.1 (95 % CI: 1.5-2.8) and OR 1.5 (95 % CI: 1.1-2.0). Boys and girls in second grade of high school with early smoking initiation reported poorer self-rated health than later initiators and never smokers. Poorer self-rated health persisted also after smoking cessation among early initiating boys. Further studies are needed to understand the adverse health effects associated with timing of smoking initiation.

Background The National Lung Screening Trial (NLST), a randomized study conducted at 33 US sites, is comparing lung cancer mortality among persons screened with reduced dose helical computerized tomography and among persons screened with chest radiograph. In this article, we present characteristics of the study population. Methods Eligible participants were aged 55–74 years and were current or former smokers with a cigarette smoking history of at least 30 pack-years. Randomization was stratified by site, sex, and age. To assess representativeness of the study population, demographic characteristics of individuals from the general population who met NLST age and smoking history inclusion criteria were obtained from the Tobacco Use Supplement of the US Census Bureau Current Population Surveys. Results The NLST enrolled 53 456 persons, with 26 733 randomly assigned to chest radiograph screening and 26 723 to computerized tomography screening. Characteristics of the participants were as follows: 31 533 (59%) were men, 39 234 (73%) were younger than 65 years, 25 779 (48%) were current smokers, and 16 839 (32%) had a college or higher degree. Median cigarette exposure was 48 pack-years. Among Tobacco Use Supplement respondents who met NLST age and smoking history criteria, 59% were men, 65% were younger than 65 years, and 57% were current smokers. Median cigarette exposure among this group was 47 pack-years, and 14% had a college degree or higher. Conclusion The NLST cohort has a distribution of sex and pack-year history that is similar to the component of the general US population that meets the major NLST eligibility criteria; however, NLST participants are younger, better educated, and less likely to be current smokers.

The strong relationship between persistent tobacco use and Major Depressive Disorder (MDD) has motivated clinical trials of specialized treatments targeting smokers with a history of MDD. Meta-analyses suggest positive responses to specialized treatments have been observed consistently among smokers with history of recurrent rather than a single episode of MDD. Approximately 15% of current US smokers have a history of recurrent MDD. Little is known about the risk factors that contribute to persistent smoking and differentiate these at-risk smokers, US. The National Comorbidity Survey - Replication (NCS-R) included a survey of 1560 smokers participants aged 18 and older in the United States. Lifetime history of MDD was categorized according to chronicity: no history (No MDD), single episode (MDD-S) and recurrent depression (MDD-R). The relationship between the chronicity of MDD, smoking characteristics, cessation history, nicotine dependence, comorbidity with psychiatric disorders, and current functional impairments were examined. MDD-R smokers reported fewer lifetime cessation efforts, smoked more cigarettes, had higher levels of nicotine dependence, had higher rates of comorbid psychiatric disorders and greater functional impairment than smokers with No MDD. MDD-S smokers were not consistently distinguished from No MDD smokers on cessation attempts, level of daily smoking, nicotine dependence or functional impairment indices. The study highlights the importance of chronicity when characterizing depression-related risk of persistent smoking behavior. Although, clinical trials suggest MDD-R smokers specifically benefit from specialized behavioral treatments, these services are not widely available and more efforts are needed to engage MDD-R smokers in efficacious treatments.

Introduction: In 2011, the Food and Drug Administration published a final rule requiring cigarette packages and advertisements to include graphic health warning labels (HWLs) with new warning statements. Implementation of this rule has been stalled by legal challenge. This study assessed correlates of smoking-related intentions related to graphic HWLs among current cigarette smokers and nonsmokers in a national sample of U.S. young adults aged 18–34. Methods: Data were collected from 4,236 participants aged 18–34 using an online panel in January 2012 for the Legacy Young Adult Cohort Study. Analyses were weighted to provide nationally representative estimates. Our main outcome was assessed with a single item: “Do you think that new warning labels with graphic pictures would make you think about not smoking?” Results: Twenty-two percent of the young adults were current cigarette smokers. Fifty-three percent endorsed that new graphic HWLs would make them think about not smoking (40% among current smokers compared with 56% among nonsmokers). Among nonsmokers, those aged 18–24, females, Hispanics, and those who were aware of graphic cigarette HWLs were more likely to report intention to not smoke related to graphic HWLs. Among current smokers, intending to quit within the next 6 months was correlated with intention resulting from graphic HWLs. Hispanic ethnicity and intention to quit within 30 days were strong correlates of intention in light, nondaily, and self-identified social/occasional smokers. Conclusions: This study supports previous findings that graphic HWLs play an important role in preventing smoking, in addition to encouraging cessation in young adults. PMID:24212476

Tobacco use is a leading preventable cause of morbidity and mortality, with nearly 6 million deaths caused by tobacco use worldwide every year (1). Cigarette smoking is the most common form of tobacco use in most countries, and the majority of adult smokers initiate smoking before age 18 years (2,3). Limiting access to cigarettes among youths is an effective strategy to curb the tobacco epidemic by preventing smoking initiation and reducing the number of new smokers (3,4). CDC used the Global Youth Tobacco Survey (GYTS) data from 45 countries to examine the prevalence of current cigarette smoking, purchase of cigarettes from retail outlets, and type of cigarette purchases made among school students aged 13-15 years. The results are presented by the six World Health Organization (WHO) regions: African Region (AFR); Eastern Mediterranean Region (EMR); European Region (EUR); Region of the Americas (AMR); South-East Asian Region (SEAR); and Western Pacific Region (WPR). Across all 45 countries, the median overall current cigarette smoking prevalence among students aged 13-15 years was 6.8% (range = 1.7% [Kazakhstan]-28.9% [Timor-Leste]); the median prevalence among boys was 9.7% (2.0% [Kazakhstan]-53.5% [Timor-Leste]), and among girls was 3.5% (0.0% [Bangladesh]-26.3% [Italy]). The proportion of current cigarette smokers aged 13-15 years who reported purchasing cigarettes from a retail outlet such as a store, street vendor, or kiosk during the past 30 days ranged from 14.9% [Latvia] to 95.1% [Montenegro], and in approximately half the countries, exceeded 50%. In the majority of countries assessed in AFR and SEAR, approximately 40% of cigarette smokers aged 13-15 years reported purchasing individual cigarettes. Approximately half of smokers in all but one country assessed in EUR reported purchasing cigarettes in packs. These findings could be used by countries to inform tobacco control strategies in the retail environment to reduce and prevent marketing and sales of tobacco products to youths (5).

To estimate changes in the prevalence of daily cannabis use among current, former, and never cigarette smokers from 2002 to 2014 in the United States. The National Survey on Drug Use and Health is a nationally representative cross-sectional study conducted annually among persons aged 12 years and older in the United States. Daily cannabis use occurs nearly exclusively among nondaily and daily cigarette smokers compared with former and never smokers (8.03%, 9.01%, 2.79%, 1.05%, respectively). Daily cannabis use increased over the past decade among both nondaily (8.03% [2014] vs 2.85% [2002]; linear trend P < .001) and daily smokers (9.01% [2014]; 4.92% [2002]; linear trend P < .001). Daily cannabis use increased most rapidly among former cigarette smokers (2.79% [2014] vs 0.98% [2002]; linear trend P < .001). Daily cannabis use occurs predominantly among cigarette smokers in the United States. Daily cannabis use increased among current, former, and never smokers over the past decade, with particularly rapid increases among youth and female cigarette smokers. Future research is needed to monitor the observed increase in daily cannabis use, especially among youths and adults who smoke cigarettes.
The effect of smoking status on burn inhalation injury mortality.
Knowlin, Laquanda; Stanford, Lindsay; Cairns, Bruce; Charles, Anthony

Three factors that effect burn mortality are age, total body surface of burn (TBSA), and inhalation injury. Of the three, inhalation injury is the strongest predictor of mortality thus its inclusion in the revised Baux score (age+TBSA+17* (inhalation injury, 1=yes, 0=no)). However, the weighted contribution of specific comorbidities such as smoker status on mortality has traditionally not been accounted for nor studied in this subset of burn patients. We therefore sought to examine the impact of current tobacco and/or marijuana smoking in patients with inhalation injury. A retrospective analysis of patients admitted to a regional burn center from 2002 to 2012. Independent variables analyzed included basic demographics, burn mechanism, presence of inhalation injury, TBSA, pre-existing comorbidities, and smoker status. Bivariate analysis was performed and logistic regression modeling using significant variables was utilized to estimate odds of mortality. There were a total of 7640 patients over the study period. 7% (n=580) of the burn cohort with inhalation injury were included in this study. In-hospital burn mortality for inhalation injury patients was 23%. Current smokers (20%) included cigarette smokers and marijuana users, 19% and 3%, respectively. Preexisting respiratory disease (17%) was present in 36% of smokers compared to 13% of non-smokers (p<0.001). Smokers had significantly lower mortality rate (9%) compared to non-smokers (26%, p<0.01). The logistic regression model for mortality outcomes identified statistically four significant variables: age, TBSA, ethnicity, and smoker status (OR=0.41, 95% CI=0.18-0.93). Presence of comorbidities, including preexisting respiratory disease, was not significant. In the sub group of burn patients with inhalation injury, the odds of mortality significantly decreased in pre-existing smokers after adjusting for significant covariates. We postulate that an immune tolerance mechanism that modulates and diminishes the pro-inflammatory response confers a survival advantage in smokers after exposure to acute smoke inhalation injury. Future prospective studies in human and/or animal models are needed to confirm these findings. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

The purpose of the present study was to determine the correlates of waterpipe (WP) smoking among 15-17-year-old high school students in Iran. Data were collected using the Global Youth Tobacco Survey (GYTS), a self-administrated questionnaire distributed to a representative sample of high school students aged 15-17 in the city of Tabriz. Current WP smoking was defined as past 30-day use, and ever WP smoking was defined as at least one or two lifetime puffs. Differences in WP use, knowledge, and attitudes were analyzed using chi-square and Fisher exact tests. Binary logistic regression estimated the association between relevant independent variables (e.g., age) and the dependent variables (current/ever WP smoking). Of 1517 students, 21.6 % (95 % confidence interval [CI] = 19.5, 23.8) were ever WP smokers, and 9.7 % (95 % CI = 8.2, 11.2) were current WP smokers. Of current WP smokers, 40.3 % have stated that they want to stop smoking now. Moreover, 14.1 % of non-WP smokers reported that they might enjoy smoking WP. Of current WP smokers, 49.0 % have smoked at cafés. Additionally, 95.3 % of current WP smokers reported that their age did not prevent them from being served a WP. Studying in high school third grade (adjusted odds ratios (AORs) = 1.70; 95 % CI [1.10, 2.63]), experience of cigarette smoking (AORs = 1.57; 95 % CI [1.12, 2.20]), and being prepared to accept a WP offered by close friends (AORs = 3.31; 95 % CI [2.17, 5.04]) were independently associated with ever WP smoking, and accepting a WP offered by close friends (AORs = 4.36; 95 % CI [2.69, 7.07]) and gender (female) (AORs = 0.45; 95 % CI [0.30, 0.70] were independently associated with current WP smoking. Prevalence of current and ever WP smoking is high in Tabriz. There is an urgent need to design interventions in order to increase students' and their parents' awareness regarding the harmfulness of WP, and to establish legal measures to restrict adolescents' access to WPs and tobacco in society.

Tobacco products are ubiquitous in most U.S. retail environments. Given that data on preferred point-of-sale purchase locations among U.S. adult tobacco users are limited, an enhanced understanding of tobacco purchase locations can help inform tobacco control policy, planning, and practice. We investigated prevalence and sociodemographic characteristics associated with cigarette purchase location among U.S. adult smokers. Pooled data came from the 2012-2013 (N=60,192) and 2013-2014 (N=75,233) National Adult Tobacco Surveys. Current cigarette smokers (n=18,005) aged ≥18 were asked if they purchased cigarettes within the previous 30days (n=15,182) and, if so, where they last purchased cigarettes. In 2016, logistic regression adjusted for sex, age, race/ethnicity, education level and annual household income was used to assess characteristics associated with purchase location. Among current smokers, 90.2% reported purchasing cigarettes in the past 30days. The most common purchase locations were convenience stores/gas stations (69.1%), tobacco discount stores (9.9%), drug stores (5.0%), supermarkets (4.9%), and liquor stores (3.6%). The odds of purchasing cigarettes at convenience stores/gas stations were higher among men (adjusted odds ratio (AOR)=1.4; 95% confidence interval (CI)=1.2-1.5) than women; and among adults aged 18-24 (AOR=3.1; 95% CI=2.4-3.9), 25-44 (AOR=3.1; 95% CI=2.7-3.7), and 45-64years (AOR=1.8 95% CI=1.6-2.1) than adults aged ≥65years. Over two-thirds of U.S. smokers last purchased cigarettes from convenience stores/gas stations. Understanding the relationship between purchase location and smoker characteristics may inform tobacco control strategies in the retail environment. Published by Elsevier Inc.
Homelessness, Cigarette Smoking, and Desire to Quit: Results from a U.S. National Study

Aims We determined whether homelessness is associated with cigarette smoking independent of other socioeconomic measures and behavioral health factors, and whether homeless smokers differ from non-homeless smokers in their desire to quit. Design, Setting, and Participants We analyzed data from 2,678 adult respondents to the 2009 Health Center Patient Survey, a nationally representative cross-sectional survey of homeless and non-homeless individuals using U.S. federally-funded community health centers. Measurements We used multivariable logistic regression to examine the association between homelessness and (1) current cigarette smoking among all adults, and (2) past-year desire to quit among current smokers, adjusting for demographic, socioeconomic, and behavioral health characteristics. Findings Adults with any history of homelessness were more likely than never homeless respondents to be current smokers (57% vs. 27%, p<0.001). In multivariable models, a history of homelessness was independently associated with current smoking (AOR 2.09; 95% CI 1.49-2.93), even after adjusting for age, sex, race, veteran status, insurance, education, employment, income, mental illness, and alcohol and drug abuse. Housing status was not significantly associated with past-year desire to stop smoking in unadjusted (p=0.26) or adjusted (p=0.60) analyses; 84% of currently homeless, 89% of formerly homeless, and 82% of never homeless smokers reported wanting to quit. Conclusions Among patients of U.S. health centers, a history of homelessness doubles the odds of being a current smoker independent of other socioeconomic factors and behavioral health conditions. However, homeless smokers do not differ from non-homeless smokers in their desire to quit and should be offered effective interventions. PMID:23834157

Background Chronic obstructive pulmonary disease is caused mainly by habitual smoking and is common among elderly individuals. It involves not only airflow limitation but also metabolic disorders, leading to increased cardiovascular morbidity and mortality. Objective We evaluated relationships among smoking habits, airflow limitation, and metabolic abnormalities. Methods Between 2001 and 2008, 15,324 school workers (9700 males, 5624 females; age: ≥30 years) underwent medical checkups, including blood tests and spirometry. They also responded to a questionnaire on smoking habits and medical history. Results Airflow limitation was more prevalent in current smokers than in ex-smokers and never-smokers in men and women. The frequency of hypertriglyceridemia was higher in current smokers in all age groups, and those of low high-density-lipoprotein cholesterolemia and diabetes mellitus were higher in current smokers in age groups ≥ 40 s in men, but not in women. There were significant differences in the frequencies of metabolic abnormalities between subjects with airflow limitations and those without in women, but not in men. Smoking index was an independent factor associated with increased frequencies of hypertriglyceridemia (OR 1.015; 95% CI: 1.012–1.018; p<0.0001) and low high-density-lipoprotein cholesterolemia (1.013; 1.010–1.016; p<0.0001) in men. Length of smoking cessation was an independent factor associated with a decreased frequency of hypertriglyceridemia (0.984; 0.975–0.994; p = 0.007). Conclusions Habitual smoking causes high incidences of airflow limitation and metabolic abnormalities. Women, but not men, with airflow limitation had higher frequencies of metabolic abnormalities.

Smoking index was an independent factor associated with increased frequencies of hypertriglyceridemia (OR 1.015; 95% CI: 1.012-1.018; p<0.0001) and low high-density-lipoprotein cholesterolemia (1.013; 1.010-1.016; p<0.0001) in men. Length of smoking cessation was an independent factor associated with a decreased frequency of hypertriglyceridemia (0.984; 0.975-0.994; p = 0.007). Habitual smoking causes high incidences of airflow limitation and metabolic abnormalities. Women, but not men, with airflow limitation had higher frequencies of metabolic abnormalities.
Use of Electronic Cigarettes Among U.S. Adults With Medical Comorbidities.

Electronic cigarette (e-cigarette) use is rising in the U.S. Smokers with comorbidities may increasingly use e-cigarettes if they believe e-cigarettes reduce smoking-related harm. This study examined e-cigarette use among adults with medical comorbidities. In 2016, this study analyzed 68,136 U.S. adults in the 2014 and 2015 National Health Interview Survey. Prevalent e-cigarette use by medical comorbidities and adjusted odds of e-cigarette use were calculated. Among current cigarette smokers, ever use of e-cigarettes was more often reported by adults with one or more medical comorbidity versus those without comorbidity (18-24 years: 73.5% vs 61.4%; 25-44 years: 60.6% vs 54.3%; 45-64 years: 46.5% vs 40.3%; ≥65 years: 35.2% vs 19.4%; all p<0.05). Current smokers aged 25-64 years with one or more comorbidity reported current e-cigarette use more often than those without comorbidity (25-44 years, 17.8% vs 14.3%, p=0.03; 45-64 years, 15.9% vs 11.5%, p=0.02). Current smokers with chronic obstructive pulmonary disease, asthma, and cardiovascular disease had higher odds of ever e-cigarette use versus those without comorbidity. Current smokers with asthma and cardiovascular disease had higher odds of current e-cigarette use. Former smokers with chronic obstructive pulmonary disease had higher odds of ever and current e-cigarette use and former smokers with cancer had lower odds of current e-cigarette use. E-cigarette use by current and former smokers with medical comorbidities is substantial, especially among individuals with chronic lung or cardiovascular disease. Clinicians should routinely ask these patients about e-cigarette use, actively consider all pathways to help their patients quit combustible cigarettes, and recommend evidence-based treatments.

Reports regarding smoking differences in α-klotho expression have provided conflicting results. In the current study we focused on the influence of smoking intensity to serum levels of the aging molecule α-klotho in healthy smokers. 40 middle aged healthy smokers without airway obstruction or restriction were selected for the analysis. Serum levels of soluble α-klotho were significantly higher in heavy smokers (P < 0.001). These results are in agreement with the possibility that α-klotho acts as anti-inflammatory molecule and strengthen the hypothesis that an increase of serum levels of α-klotho might be a compensatory response to smoking stress in healthy population.

Previous studies have shown conflicting results on the association between smoking and cognitive function. This study aims to examine the relationship of smoking with cognitive function. Data for the study, consisting of 2553 older adults aged 60 years and older, were drawn from a nationwide household survey entitled "Determinants of Wellness among Older Malaysians: A Health Promotion Perspective" conducted in 2010. Current smokers had lower rates of cognitive impairment compared to never smokers (17.4% vs 25.9%), while cognitive function in former or ex-smokers was almost similar to that of the never smokers. Findings from multiple logistic regression analysis showed that current smokers were 37% less likely to be cognitively impaired, compared to the never smokers (odds ratio [OR] = .63; 95% confidence interval [CI]: .46-.86) while controlling for potential confounders. No difference in cognitive function was observed between former smokers and never smokers (OR = .94; 95% CI: .71-1.25). Although the findings indicated a negative association between cigarette smoking and cognitive impairment, we are unable to conclude whether this relationship is causal or affected by other unmeasured confounding factors, especially survival bias. © The Author(s) 2014.

To investigate the frequency of advice to quit smoking received by the Italian population from general practitioners (GP) and dentists, we analyzed a cross-sectional study. A face-to-face survey was conducted in 2014 on 3052 individuals, representative of the general Italian population aged 15 years or more. During the previous year, 89% of individuals (82% of smokers) reported that they had visited a GP while 71% (67% of smokers) had visited a dentist. Among smokers, 25% reported that they had received advice to quit smoking from their GP, and 26% from their dentist. Advice by GPs was less frequently received by smokers with higher education (multivariate odds ratios (OR) were 0.48 for intermediate and 0.38 for high as compared to low education), and more frequently by heavy smokers (≥15 cigarettes/day; OR = 1.78), those with intention to quit (OR = 2.59), with previous quit attempts (OR = 2.09), and those aware of the existence of smoking cessation services (OR = 1.59). Advice by dentists was more frequently received by smokers aged 25-44 years (OR = 3.55 compared to those aged 15-24) and those with an intention to quit (OR = 2.46). Among Italian current smokers, 32% reported that their GP and 17% that their dentist was a current smoker. The corresponding figures among young smokers were 40% and 26%, respectively. Healthcare providers have the potential to become a key reference point in the fight against smoking. However, before acting, GPs and dentists should set a good example: those who smoke should urgently quit or at least refrain from smoking during working hours. GPs and dentists, reaching the large majority of Italian smokers, can make a major contribution in the fight against tobacco. Future studies are needed to investigate possible reasons of the apparently high smoking prevalence among GPs, in order to develop tailored smoking cessation interventions for healthcare providers. © The Author 2016.

This study incorporates intersectionality theory to address potential effects of age on other documented risk factors for current smoking and menthol cigarette use in young adults aged 18-34 using Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study (2013-2014). We explored known correlates of current cigarette and menthol cigarette smoking and interaction analyses by age group (18-24 vs. 25-34), accounting for survey weighting. Use of non-cigarette tobacco products and e-cigarettes was characterized among current cigarette smokers. Young adults experience multiple vulnerabilities to smoking beyond age and some of these known risk factors for smoking place those aged 18-24 at different risk of cigarette smoking compared to their 25-34 year old counterparts. These include lower odds of cigarette smoking by age for sex (female; AOR = 0.62 in those aged 18-24 vs. 0.72 in those aged 25-34) and Hispanic ethnicity (vs. White; AOR = 0.77 vs. 0.45), and higher odds of smoking among past 30-day alcohol users aged 18-24 vs. 25-34 (AOR = 1.62 vs. 1.32). Correlations between lower education and smoking were nearly two-fold higher in 25-34 than 18-24 year olds. Having any medical comorbidity had opposite effects on current smoking by age (18-24 positive correlation, AOR = 1.17; 25-34 negative correlation, AOR = 0.84). Lower education was correlated with menthol cigarette use among young adult smokers. This study suggests that higher smoking prevalence among young adults is associated with the intersection of multiple vulnerabilities to smoking. Copyright © 2018 Elsevier Inc. All rights reserved.

Several studies have reported an association between cigarette smoking and psychiatric illness. A common finding is that the prevalence of psychiatric illness among former smokers is much lower than among current smokers and is often similar to that among never-smokers. There are two alternative causal explanations for this association: either improved mental well-being results from smoking cessation; or those with poorer mental well-being are less successful at smoking cessation. The objective was to analyse a unique longitudinal data set to shed light on the direction of causality and to distinguish between these alternative explanations. Information on smoking status and indicators of poor mental well-being from childhood and adolescence was collected at age 18 in 1969 from 49 321 men at compulsory conscription for military service. Follow-up data on smoking status were collected among a random subset (n = 694) who participated in one or more annual national Swedish Surveys of Living Conditions in 1981-2001. Approximately half of the smokers at age 18 in 1969 had quit by the time they were resurveyed (1981-2002). Those who had not quit and who reported smoking more than 10 cigarettes/day at age 18 (called persistent heavy smokers), were more likely to have had childhood and adolescent indicators of poor mental health measured at age 18 in 1969 than non-smokers or quitters. Our findings indicate that men who would subsequently be successful at smoking cessation reported better mental health and a lower prevalence of childhood mental health indicators at age 18 than persistent heavy smokers.

Both anti- and proinflammatory effects of cigarette smoking have been described. As prostate inflammation is common, we hypothesized smoking could contribute to prostate inflammation. Thus, we evaluated the association of smoking status with acute and chronic inflammation within the prostate of men undergoing prostate biopsy. We retrospectively analyzed 8,190 men ages 50 to 75 years with PSA levels between 2.5 and 10 ng/mL enrolled in the Reduction by Dutasteride of Prostate Cancer Events study. Smoking status was self-defined as never, former, or current. Prostate inflammation was assessed by systematic central review blinded to smoking status. The association of smoking with inflammation in the baseline, 2-year, and 4-year biopsies was evaluated with univariable and multivariable logistic regressions. At study enrollment, 1,233 (15%), 3,203 (39%), and 3,754 (46%) men were current, former, and never smokers, respectively. Current smokers were significantly younger and had smaller prostates than former and never smokers (all P < 0.05). Former smokers were significantly heavier than current and never smokers (P < 0.001). Acute and chronic prostate inflammations were identified in 1,261 (15%) and 6,352 (78%) baseline biopsies, respectively. In univariable analysis, current smokers were more likely to have acute inflammation than former (OR, 1.35; P, 0.001) and never smokers (OR, 1.36; P, 0.001). The results were unchanged at 2- and 4-year biopsies. In contrast, current smoking was linked with chronic inflammation in the baseline biopsy, but not at 2- and 4-year biopsies. In conclusion, among men undergoing prostate biopsy, current smoking was independently associated with acute and possibly chronic prostate inflammations. ©2015 American Association for Cancer Research.

The present study examined effects of current and past regular cigarette smoking in young adult subjects. One hundred and twelve 17-21-year-old subjects, assessed since infancy, were evaluated using a battery of neurocognitive tests for which commensurate measures were obtained at 9-12 years of age, prior to the initiation of regular smoking. Smokers, determined by urinalysis and self-report, were categorized as heavy (>9 cigarettes per day) and light (<9 cigarettes per day) current smokers and former smokers, the latter having smoked cigarettes regularly in the past but not for at least 6 months. A third of the subjects were currently smoking cigarettes regularly with half of these being heavy smokers. Among former smokers, the average duration of smoking was slightly less than 2 years. Overall IQ, memory, processing speed, vocabulary, attention and abstract reasoning were the primary outcomes with comparisons being made between each of the three user groups and a control group who never smoked regularly. After accounting for potentially confounding factors including clinical assessment, marihuana use and pre-drug performance in the relevant cognitive domain, current regular smokers did significantly worse than non-smokers in a variety of cognitive areas predicated upon verbal/auditory competence including receptive and expressive vocabulary, oral arithmetic, and auditory memory. This impact of current smoking appears to behave in a dose-response and duration-related fashion. In contrast, former smokers differed from the non-smokers only in the arithmetic task. These results suggest that regular smoking during early adulthood is associated with cognitive impairments in selected domains and that these deficits may be reversed upon cessation. Together, the findings add to the body of evidence to be used in persuading adolescents and young adults against the initiation of smoking and, if currently smoking, the advantages of stopping.
Can you please put it out? Predicting non-smokers' assertiveness intentions at work.

The present study aimed to identify the psychosocial predictors of non-smoker employee intentions to ask smokers not to smoke at work. The predictive effects of past behaviour, anticipated regret, social norms, attitudinal, outcome expectancy and behavioural control beliefs were investigated in relation to the Attitudes-Social influence-self-Efficacy (ASE) model. Data were collected from Greek non-smoker employees (n=137, mean age=33.5, SD=10.5, 54.7% female) in 15 companies. The main outcome measure was assertiveness intention. Data on participants' past smoking, age, gender and on current smoking policy in the company were also collected. The majority of employees (77.4%) reported being annoyed by exposure to passive smoking at work, but only 37% reported having asked a smoker colleague not to smoke in the last 30 days. Regression analysis showed that the strongest predictor of non-smokers' assertiveness intentions was how often they believed that other non-smokers were assertive. Perceived control over being assertive, annoyance with secondhand smoke (SHS) exposure at work and past assertive behaviour also significantly predicted assertiveness intentions. Assertiveness by non-smoker employees seems to be guided mainly by normative and behavioural control beliefs, annoyance with SHS exposure at work, and past behaviour. Interventions to promote assertiveness in non-smokers might benefit from efficacy training combined with conveying the messages that the majority of other non-smokers are frequently annoyed by exposure to SHS, and that nearly half of all non-smokers are assertive towards smokers.

The general population is nowadays well aware that tobacco smoking dramatically increases the risk of developing lung cancer. We hypothesized that a personal history of smoking and the level of nicotine dependence in current smokers may affect the perception of this risk among healthy individuals. The fourth French nationwide observational survey, EDIFICE 4, was conducted by telephone among a representative sample of individuals (N = 1602) aged between 40 and 75 years. Interviewees were asked about their smoking habits, perception of the risk of lung cancer, and nicotine dependence (Fagerström test). Regardless of their smoking status or level of nicotine dependence, the majority (96%) of our study population (N = 1463) acknowledged that tobacco smoking is a major risk factor for lung cancer. For 34% of all respondents, smoking ≤ 10 cigarettes per day does not carry any risk of lung cancer. Only half the current smokers considered themselves to be at higher risk of lung cancer than the average-risk population. The majority of current cigarette smokers with a nicotine dependence considered themselves to be at higher risk for lung cancer while only 37% of non-nicotine-dependent individuals had the same perception (P < 0.01). Current smokers were more likely to consider a screening examination than former smokers and never-smokers. However, the intention to undergo screening was not significantly affected by the level of nicotine dependence. Awareness campaigns may first have to overcome misconceptions about light smoking and, secondly, to target specific populations (heavy smokers, those with a long history, highly dependent smokers).

To examine the associations between smoking and cardiovascular disease (CVD) / coronary heart disease (CHD) and all-cause mortality events in men with and without type 2 diabetes (T2D) in a Middle Eastern cohort during a median follow-up of 12 years. The study population included 2230 subjects aged ≥ 40 years, free from CVD, comprised of 367 participants with diabetes (21.2% current smokers) and 1863 without (27.3% current smokers). Multivariate Hazard ratios (HR) and 95% confidence intervals (CI) were calculated for smoking (considering different definitions) for those with and without diabetes. Potential confounding factors including age, body mass index, estimated Glomerular Filtration Rate, hypertension, hypercholesterolemia and educational level were entered in the multivariate analysis. In men with diabetes, the HR (95% CI) of comparing current and non-smokers was 1.25 (0.74-2.12) for incident CHD, 1.52 (0.96-2.40) for CVD and 2.10 (1.27-3.47) for mortality events; the corresponding values for men without diabetes were 1.65 (1.24-2.20), 1.70 (1.30-2.22) and 1.72 (1.14-2.58), respectively (all P values for interactions > 0.46). After pooling past smokers with current smokers, among diabetic individuals there was no significant risk for CVD [1.29 (0.89-1.86)] or mortality events [1.25 (0.81-1.92)]; however, among non-diabetic individuals the HRs of current/past smokers reached significant levels for CVD [1.53 (1.23-1.91)] but not for mortality outcomes (all P values for interactions > 0.51). The strength of the associations between smoking habits and incident CVD/CHD and mortality events from all causes did not differ significantly among diabetic and non-diabetic participants. Therefore, a comprehensive community-based smoking prevention program is important, given the increasing trend of smoking among the Iranian population regardless of diabetes status.

To analyse clinical severity/activity of rheumatoid arthritis (RA) according to smoking status. The QUEST-RA multinational database reviews patients for Core Data Set measures including 28 swollen and tender joint count, physician global estimate, erythrocyte sedimentation rate (ESR), HAQ-function, pain, and patient global estimate, as well as DAS28, rheumatoid factor (RF), nodules, erosions and number of DMARDs were recorded. Smoking status was assessed by self-report as 'never smoked', 'currently smoking' and 'former smokers'. Patient groups with different smoking status were compared for demographic and RA measures. Among the 7,307 patients with smoking data available, status as 'never smoked,' 'current smoker' and 'former smoker' were reported by 65%, 15% and 20%. Ever smokers were more likely to be RF-positive (OR 1.32;1.17-1.48, p<0.001). Rheumatoid nodules were more frequent in ever smokers (OR 1.41;1.24-1.59, p<0.001). The percentage of patients with erosive arthritis and extra-articular disease was similar in all smoking categories. Mean DAS28 was 4.4 (SD 1.6) in non-smokers vs. 4.0 (SD 1.6) in those who had ever smoked. However, when adjusted by age, sex, disease duration, and country gross domestic product, only ESR remained significantly different among Core Data Set measures (mean 31.7mm in non-smokers vs. 26.8mm in ever smoked category). RA patients who had ever smoked were more likely to have RF and nodules, but values for other clinical status measures were similar in all smoking categories (never smoked, current smokers and former smokers).

This study reports consumer reactions to the graphic health warnings selected by the Food and Drug Administration to be placed on cigarette packs in the United States. We recruited three sets of respondents for an experimental study from a national opt-in e-mail list sample: (i) current smokers aged 25 or older, (ii) young adult smokers aged 18-24 and (iii) youth aged 13-17 who are current smokers or who may be susceptible to initiation of smoking. Participants were randomly assigned to be exposed to a pack of cigarettes with one of nine graphic health warnings or with a text-only warning statement. All three age groups had overall strong negative emotional (ß = 4.7, P < 0.001 for adults; ß = 4.6, P < 0.001 for young adults and ß = 4.0, P < 0.001 for youth) and cognitive (ß = 2.4, P < 0.001 for adults; ß = 3.0, P < 0.001 for young adults and ß = 4.6, P < 0.001 for youth) reactions to the proposed labels. The strong negative emotional and cognitive reactions following a single exposure to the graphic health warnings suggest that, with repeated exposures over time, graphic health warnings may influence smokers' beliefs, intentions and behaviors. © The Author 2014.

Nicotine replacement therapy (NRT) is used by smokers wanting to reduce their smoking and to quit. However, there are very little data on nicotine intake associated with NRT use in representative population samples. This study aimed to provide estimates for NRT use and associated nicotine exposure among smokers, recent and longer-term ex-smokers in England, a country with a permissive regulatory regime for nicotine substitution. In the Smoking Toolkit Study, a monthly series of representative household surveys of adults aged 16+ in England, current and recent ex-smokers who agreed to be re-contacted were followed up 6 months later and standard socio-demographic and smoking characteristics assessed (N = 5,467, response rate 25.1%). A random sub-sample (N = 1,614; 29.5%) also provided saliva, analysed for cotinine. The sample followed up was broadly representative of the original sample. At follow-up, 11.8% (95%CI 10.9-12.8, N = 565) of current smokers, 34.8% (95%CI 28.9-41.3, N = 77) of recent (≤ 3 months) ex-smokers, and 7.8% (95%CI 5.6-10.6, N = 36) of longer-term (> 3 months) ex-smokers reported using NRT. Smokers who used NRT had similar saliva cotinine concentrations to smokers who did not use NRT (mean ± sd = 356.0 ± 198.6 ng/ml vs. 313.1 ± 178.4 ng/ml). Recent ex-smokers who used NRT had levels that were somewhat lower, but not significantly so, than current smokers (216.7 ± 179.3 ng/ml). Longer-term ex-smokers using NRT had still lower levels (157.3 ± 227.1 ng/ml), which differed significantly from smokers using NRT (p = 0.024). Concurrent use of nicotine replacement therapy while smoking is relatively uncommon and is not associated with higher levels of nicotine intake. Among ex-smokers, NRT use is common in the short but not longer-term and among longer-term users is associated with lower nicotine intake than in smokers.

Background According to the 2004 Surgeon General’s Report on Health Consequences of Smoking, after >15 years of abstinence, the cardiovascular risk of former smokers becomes similar to that of never-smokers. Whether this health benefit of smoking cessation varies by amount and duration of prior smoking remains unclear. Methods and Results Of the 4482 adults ≥65 years without prevalent heart failure (HF) in the Cardiovascular Health Study (CHS), 2556 were never-smokers, 629 current smokers, and 1297 former smokers with >15 years of cessation, of whom 312 were heavy smokers (highest quartile; ≥32 pack-years). Age-sex-race-adjusted hazard ratios (aHR) and 95% confidence intervals (CI) for centrally-adjudicated incident HF and mortality during 13 years of follow-up were estimated using Cox regression models. Compared to never-smokers, former smokers as a group had similar risk for incident HF (aHR, 0.99; 95% CI, 0.85–1.16) and all-cause mortality (aHR, 1.08; 95% CI, 0.96–1.20), but former heavy smokers had higher risk for both HF (aHR, 1.45; 95% CI, 1.15–1.83) and mortality (aHR, 1.38; 95% CI, 1.17–1.64). However, when compared to current smokers, former heavy smokers had lower risk of death (aHR, 0.64; 95% CI, 0.53–0.77), but not of HF (aHR, 0.97; 95% CI, 0.74–1.28). Conclusions After >15 years of smoking cessation, older adults who smoked <32 pack-years appear to achieve the health profile of never-smokers. Although former heavy (≥32 pack-years) smokers may not achieve this health benefit of prolonged smoking cessation, their risk is clearly lower relative to current smokers. PMID:26038535

Individuals with binge eating disorder (BED) report smoking to control appetite and weight. Smoking in BED is associated with increased risk for comorbid psychiatric disorders, but its impact on psychosocial functioning and metabolic function has not been evaluated. Participants were 429 treatment-seeking adults (72.4% women; mean age 46.2±11.0years old) with BED comorbid with obesity. Participants were categorized into current smokers (n=66), former smokers (n=145), and never smokers (n=218). Smoking status was unrelated to most historical eating/weight variables and to current eating disorder psychopathology. Smoking status was associated with psychiatric, psychosocial, and metabolic functioning. Compared with never smokers, current smokers were more likely to meet lifetime diagnostic criteria for alcohol (OR=5.51 [95% CI=2.46-12.33]) and substance use disorders (OR=7.05 [95% CI=3.37-14.72]), poorer current physical quality of life, and increased risk for metabolic syndrome (OR=1.80 [95% CI=0.97-3.35]) and related metabolic risks (reduced HDL, elevated total cholesterol). On the other hand, the odds of meeting criteria for lifetime psychiatric comorbidity or metabolic abnormalities were not significantly greater in former smokers, relative to never smokers. Our findings suggest the importance of promoting smoking cessation in treatment-seeking patients with BED and obesity for its potential long-term implications for psychiatric and metabolic functioning.

Background: Never smokers comprise a substantial proportion of patients with COPD. Their characteristics and possible risk factors in this population are not yet well defined. Methods: We analyzed data from 14 countries that participated in the international, population-based Burden of Obstructive Lung Disease (BOLD) study. Participants were aged ≥ 40 years and completed postbronchodilator spirometry testing plus questionnaires about respiratory symptoms, health status, and exposure to COPD risk factors. A diagnosis of COPD was based on the postbronchodilator FEV1/FVC ratio, according to current GOLD (Global Initiative for Obstructive Lung Disease) guidelines. In addition to this, the lower limit of normal (LLN) was evaluated as an alternative threshold for the FEV1/FVC ratio. Results: Among 4,291 never smokers, 6.6% met criteria for mild (GOLD stage I) COPD, and 5.6% met criteria for moderate to very severe (GOLD stage II+) COPD. Although never smokers were less likely to have COPD and had less severe COPD than ever smokers, never smokers nonetheless comprised 23.3% (240/1,031) of those classified with GOLD stage II+ COPD. This proportion was similar, 20.5% (171/832), even when the LLN was used as a threshold for the FEV1/FVC ratio. Predictors of COPD in never smokers include age, education, occupational exposure, childhood respiratory diseases, and BMI alterations. Conclusion: This multicenter international study confirms previous evidence that never smokers comprise a substantial proportion of individuals with COPD. Our data suggest that, in addition to increased age, a prior diagnosis of asthma and, among women, lower education levels are associated with an increased risk for COPD among never smokers.

Studies have shown that cigarette smoking is associated with sleep disorders in the general population. But studies examining the association between smokeless tobacco use, second-hand smoke exposure and insufficient rest/sleep are limited. We examined the association between smoking, smokeless tobacco use (n=83,072), second-hand smoke exposure (n=28,557) and insufficient rest/sleep among adults aged ≥20 years in the state-based 2008 Behavioral Risk Factor Surveillance System. Exposure to second-hand smoke was defined as >1 day of exposure to cigarette smoking either at home or in the workplace in the preceding 7 days. Insufficient rest/sleep was defined as not getting enough rest/sleep everyday in the preceding 30 days. Compared to never smokeless tobacco users, the odds ratio (OR; 95% confidence interval [CI]) of insufficient rest/sleep was 1.16 (1.00-1.36) and 1.74 (1.37-2.22) among former and current users. Compared to non-smokers/non-smokeless tobacco users, the OR (95% CI) of insufficient rest/sleep for those who were both current smokers and current smokeless tobacco users was 2.21 (1.66-2.94). Regarding second-hand smoke exposure among non-smokers, those with second-hand smoke exposure had higher odds for insufficient rest/sleep than those without. In contrast, the odds of insufficient rest/sleep were similar among current smokers with or without second-hand smoke exposure. In a multiethnic sample of US adults, compared to non-smokers/non-smokeless tobacco users, those who were both current smokers and current smokeless tobacco users had twice the odds of insufficient sleep. Second-hand smoke exposure was associated with insufficient rest/sleep among non-smokers. Copyright © 2010 Elsevier B.V. All rights reserved.

Lung age, a simple concept for patients to grasp, is frequently used as an aid in smoking cessation programs. Lung age equations should be continuously updated and should be made relevant for target populations. We observed how new lung age equations developed for Australian populations performed when utilizing the Burden of Obstructive Lung Disease (BOLD)-Australia dataset compared to more commonly used equations. Data from a cross-sectional population study of noninstitutionalized Australians aged ≥40 years with analysis restricted to Caucasians <75 years. Lung age calculated using equations developed by Newbury et al. and Morris and Temple was compared with chronological age by smoking status and within smoking status. There were 2,793 participants with a mean age of 57 (±10 SD) years. More than half (52%) ever smoked, and 10.4% were current smokers. Prevalence of chronic obstructive pulmonary disease stage I or higher was 13.4% (95% confidence interval = 12.2, 14.7). For both genders, newer Newbury equations estimated lung ages significantly higher than actual age across all smoking groups (p < .05). Morris and Temple equations resulted in lung age estimates significantly lower than chronological age for nonsmokers (p < .05) but no difference among current smokers. Both equations showed exposure to smoking had lung ages higher than never-smokers (p < .001). Lung age also increased with increased pack-years. This supports the use of updated equations suited to the population of interest. The Australian Newbury equations performed well in the BOLD-Australia dataset, providing more meaningful lung age profile compared to chronological age among smokers. Using equations not developed or ideally suited for our population is likely to produce misleading results. © The Author 2014.

Harm perceptions of menthol cigarettes may contribute to their appeal and use. African-Americans, women, and younger smokers disproportionately use menthol cigarettes, and may misperceive harm of menthol cigarettes. Data were from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study. Weighted analyses of current adult smokers (18 and older) were used to estimate the correlates of menthol smoking among all cigarette brands and separately for the top three cigarette brands (Newport, Camel, and Marlboro). Adjusted models examined the main effect of menthol smoking on harm perceptions of one's own brand of cigarette and interactions with race/ethnicity, age, and gender. Menthol cigarettes were used by nearly 40% of current smokers, although the prevalence of menthol smoking differed across the top three brands (94% Newport, 46% Camel, and 18% Marlboro). Among menthol smokers, 80% perceived their cigarette as equally harmful, 14% perceived their brand as more harmful, and 7% perceived their brand as less harmful. In adjusted models, menthol smokers were more likely than nonmenthol smokers to misperceive their own brand as more harmful than other brands (compared to no difference in harm). Race and gender emerged as moderators of the association between menthol brand preference and harm perceptions. In adjusted analyses, menthol smokers were more likely than nonmenthol smokers to perceive their brand as more harmful than other brands, with differences by sub-groups who disproportionately use menthol. Menthol cigarettes have been historically marketed with messages conveying lower harm than other cigarettes. Little is known about how contemporary adult menthol smokers perceive the harm of their usual brand, and potential differences by race, gender, and young adult versus older adult age group. After adjusting for other factors, menthol smokers were more likely than nonmenthol smokers to perceive their cigarette brand as more harmful than other brands. Further, the association between menthol smoking and harm perceptions differed by race and gender, but not by age group (young adult vs. older adult). This type of large-scale study identifies critical links between menthol smoking and harm perceptions among vulnerable smokers that will inform regulatory actions designed to decrease smoking-related harm. © The Author(s) 2018.

This study assessed the prevalence and determinants of e-cigarette use among persons aged ≥15 years in 27 European Union (EU) member countries during 2012. The 2012 Eurobarometer 385 (77.1) survey was analysed for n=26 566 respondents. Knowledge, perception of harm, and determinants of e-cigarettes use were assessed, while separate regression analyses among current (n=7352) and former cigarette smokers (n=5782) were performed. National estimates of the number of e-cigarette users were also extrapolated. 20.3% of current smokers, 4.7% of ex-smokers, and 1.2% of never cigarette smokers in the EU reported having ever used an e-cigarette (overall approximately 29.3 million adults). Among smokers, ever e-cigarette use was more likely among 15-24-year-olds (aOR 3.13, 95% CI 2.22 to 4.54) and 25-39-year-olds (aOR 2.00, 95% CI 1.47 to 2.78) in comparison to older smokers, and among those who smoked 6-10 cigarettes/day (aOR 1.53, 95% CI 1.10 to 2.13) or 11-20 cigarettes/day (aOR 2.07, 95% CI 1.52 to 2.81) in comparison to very light smokers (≤5 cigarettes/day). Moreover, e-cigarette use was more likely among smokers who had made a past year quit attempt (aOR 2.08, 95% CI 1.67 to 2.58). E-cigarette use among ex-smokers was associated only with the respondents' age, with younger ex-smokers being more likely to have ever used an e-cigarette. A substantial number of EU adults have ever used e-cigarettes. Ever users were more likely to be younger, current smokers, or past-year quit attempters. These findings underscore the need to evaluate the potential long term impact of e-cigarette use on consumer health, cessation and nicotine addiction and formulate a European framework for e-cigarette regulation within the revised EU Tobacco Product Directive.

Little is currently known about price sensitivity across ethnic groups as well as for non-daily smokers. To address this issue, this study compared perceived price sensitivity across smoking status (daily and non-daily) and within ethnicity (Hispanic and non-Hispanic White) in a recent representative population survey of California smokers. This study employed data from the 2008 California Tobacco Survey (CTS), a large population-based random-digit-dialed telephone survey. Participants were 1,777 non-Hispanic White and 450 Hispanic respondents who had smoked at least 100 cigarettes and currently smoked daily or on some days. Differences in perceived price sensitivity were found by ethnicity when controlling for age, gender, and cigarette consumption. Comparisons across ethnic groups indicated that Hispanic smokers, in general, have more price-sensitive perceptions than non-Hispanic White smokers. However, daily versus non-daily status had no effect on price sensitivity when controlling for cigarette quantity. These findings indicate that pricing increases may be differentially influential for Hispanic compared with non-Hispanic White smokers across smoking status categories.

Smoking is recognized as a main leading preventable cause of mortality and morbidity worldwide. It is responsible for a considerable nancial burden both on the health system and in society. This study aimed to examine the effect of smoking on cost of hospitalization and length of stay (LoS) among patients with lung cancer in Iran in 2014. A total of 415 patients were included in the study. Data on age, sex, insurance status, type of hospitals, type of insurance, geographic local, length of stay and cost of hospitalization was extracted by medical records and smoking status was obtained from a telephone survey. To compare cost of hospitalization and LoS for different smoking groups, current smokers, former smokers, and never smokers, a gamma regression model and zero-truncated poisson regression were used, respectively. Compared with never smokers, current and former smokers showed a 48% and 35% increase in hospitalization costs, respectively. Also, hospital LoS for current and former smokers was 72% and 31% higher than for never smokers, respectively. Our study indicated that cigarette smoking imposes a signi cant nancial burden on hospitals in Iran. It is, however, recommended that more research should be done to implement and evaluate hospital based smoking cessation interventions to better increase cessation rates in these settings.

Assessment of health-related quality of life (HRQoL) is well established in clinical research, but ceiling effects in validated tools might prevent detection of changes in well respondents. Tobacco Quality of Life Impact Tool (TQOLITv1) uses conceptual and psychometric advances to enhance detection of HRQoL changes. In a 6-month, forced-switch study, the German TQOLITv1 was assessed in healthy adult (age 23-55 years) current and matched former-smokers. At baseline, smokers were switched to reduced toxicant prototype (RTP) or conventional cigarette for 6 months. TQOLITv1 responses were collected at baseline, 3 and 6 months from current smokers whilst former smokers completed it at the latter two time points. TQOLITv1 includes SF-36v2 and new smoking-specific, physical and general-health measures. Reliability at baseline was good (Cronbach's coefficient alpha > 0.70) for all measures. The baseline percentage with the best possible score (ceiling effect) for former and current smokers was substantially better for the new physical function than SF-36 physical function measure (35% vs. 59% at ceiling, respectively). New smoking-specific measures discriminated current from former smokers better than general health measures. Smoking-specific symptoms (r = 0.73) were more stable from baseline to 6 months than other measures (r = 0.38-0.54) particularly more than the SF-36 mental component score (r = 0.24). Although both product smoking groups worsened in most HRQoL measures, changes in general and smoking-specific HRQoL impact measures favored RTP smokers. The German TQOLITv1 is sufficiently reliable and valid to assess HRQoL and may be more useful than SF-36v2 in evaluation of interventions in well smoking populations including those consuming RTPs. © The Author 2015.

To compare the characteristics of smokers who do and do not receive smoking cessation treatment in primary care. Prospective cohort study using practices registered with the pilot QRESEARCH database. 156,550 patients aged 18 years and over from 39 general practices located within four strategic health authorities, representing the former Trent Region, UK. Patients registered with practices between 1 April 2001 and 31 March 2003 aged 18 years and over who were identified as smokers before the two year study period. Prescription for smoking cessation treatment (nicotine replacement therapy (NRT) or bupropion) in the two year study period. Age, sex, deprivation score, co-morbidity. Of the 29,492 patients recorded as current smokers at the start of the study period 1892 (6.4%) were given prescriptions for smoking cessation treatment during the subsequent two years. Of these, 1378 (72.8%) were given NRT alone, 406 (21.5%) bupropion alone, and 108 (5.7%) both treatments. Smokers were more likely to receive smoking cessation treatment if they lived in the most deprived areas (odds ratio (OR) for the most relative to the least deprived fifth, adjusted for sex, age, and co-morbidity, 1.50, 95% confidence interval (CI) 1.26 to 1.78), and if they were aged 25-74 years compared to 18-24 years or 75 and over. Smokers with co-morbidity were also more likely to receive smoking cessation treatment. Smokers were less likely to receive smoking cessation treatment if they were male (adjusted OR 0.68, 95% CI 0.62 to 0.75). The low proportion of smokers being prescribed these products strongly suggests that a major public health opportunity to prevent smoking related illness is being missed.

The objective of this study was to examine the smoking behavior among adolescents in Thailand and Malaysia. Population-based, national surveys were conducted among 1,704 adolescents between the ages of 13 and 18 from Thailand (n = 927) and Malaysia (n = 777). Respondents were selected using multistage cluster sampling. Respondents were asked to complete self-administered questionnaires. Approximately 5% of Thai and Malaysian adolescents were current smokers, while an additional 8.6% of Thai and 8.1% of Malaysian adolescents reported being beginning smokers. On average, Thai smokers reported first smoking a whole cigarette at 14.6 years old (SD = 1.9), while Malaysian smokers at age 13.9 years (SD = 2.2). More than half of Thai smokers (60.4%) reported they bought cigarettes themselves and 29.9% got cigarettes from friends. In Malaysia, most smokers (68.3%) reported they bought cigarettes themselves, only 20.7% got cigarettes from friends. Seventy-six percent of Thai adolescent smokers smoked factory-made brands as their usual brand compared to 27.7% of Malaysian adolescent smokers. Eight percent of Thai adolescents and 10% of Malaysian adolescents reported smoking hand-rolled cigarettes. Approximately half of Thais and more than 40% of Malaysian smokers reported they tried to quit smoking within the past month. The smoking prevalence of Thai adolescents is close to that of Malaysian adolescents. Factory-made cigarette consumption is an important problem in Thai adolescents and needs to be targeted.

Health warning labels on cigarette packages are among the most straightforward and important tools to communicate with smokers and various studies have illustrated their efficacy. The current study aimed to investigate the opinions of male smokers in Mashhad city about the efficacy of health warning labels printed on cigarette packages on the smoking status of smokers. This cross-sectional descriptive study was conducted in 2013 using a questionnaire. The research population included the male smokers of Mashhad. The participants were selected from the customers referring to the newsstands for cigarettes. The obtained data were analyzed employing SPSS software Version 16, and the statistical tests including Kruskal-Wallis, Spearman, and correlation coefficient of Pearson, Chi Square, Mann-Whitney, and Bonferroni correction were used in this regard. In this research, there were 500 participants with the average age of 25 years. The initiation age of smoking was eight years while the maximum age was reported as 45 years. Results of this research about the effect of these labels on decreasing cigarette consumption rate showed that almost half of the participants believed that these labels were ineffective for them (52.2%) and other smokers (53.8%).Furthermore, significant relationship was found between the age and opinion of the smokers about the influence of these labels on reducing their cigarette consumption (P < 0.001). To promote the effect of printed images on cigarette packages, it is recommended to consider the suitability of labels in the targeted culture. In addition, to be more effective consultation sites to quit smoking should be introduced under the images.
Tobacco use among high shool students in Kampala, Uganda: questionnaire study.

To determine the prevalence of tobacco-use and describe tobacco-related knowledge, perceptions, and behavior of high school students aged 13-15 years in Kampala, Uganda. A cross-sectional questionnaire study was carried out among 2,789 students in 19 high schools in Kampala District, Uganda, in 2002. In each school, three classes from Senior One to Senior Three (average student age, 13 to 15 years, respectively) were randomly selected. All students who consented to participate in the study filled out a questionnaire consisting of 58 questions, with core items selected from the Global Youth Tobacco Survey. The questions were grouped into categories relating to tobacco use, knowledge and attitudes toward smoking, exposure to second hand smoke, attitude toward cessation of smoking, exposure to tobacco-related advertisements in the media, and education on tobacco and smoking in school. Out of 2,789 students, 488 (17.5%) reported to have smoked tobacco, with 185 (37.9%) of them trying or starting smoking before the age of 10. There were 148 (5.3%) current smokers. More than two-thirds (77.9%) of current smokers expressed a desire to stop smoking, 76.9% had tried to stop, and 84.1% had received help or advice to stop smoking. At least two-thirds of the students reported seeing both anti-tobacco and pro-tobacco advertisements in the preceding month. About 15.7 % of the students had an item with a cigarette brand logo, whereas 11.1% had been offered free cigarettes by a tobacco company representative. Current smokers usually smoked at home (30.2%), at a friend's place (29.3%), in public places (12.1%), at social events (10.4%), and at workplace (1.5%). Current smokers were also more likely than non-smokers to be exposed to passive smoking at home (56.4% vs at 15.9%, respectively; p<0.001). Many high school students in Kampala are exposed to tobacco advertising, especially through the media. Efforts to control smoking in this age-group should also target their parents and other family members, by means of the media.

Background: Severe COPD can lead to cor pulmonale and emphysema and is associated with impaired left ventricular (LV) filling. We evaluated whether emphysema and airflow obstruction would be associated with changes in right ventricular (RV) structure and function and whether these associations would differ by smoking status. Methods: The Multi-Ethnic Study of Atherosclerosis (MESA) performed cardiac MRI on 5,098 participants without clinical cardiovascular disease aged 45 to 84 years. RV and emphysema measures were available for 4,188 participants. Percent emphysema was defined as the percentage of voxels below −910 Hounsfield units in the lung windows on cardiac CT scans. Generalized additive models were used to control for confounders and adjust for respective LV parameters. Results: Participants consisted of 13% current smokers, 36% former smokers, and 52% never smokers. Percent emphysema was inversely associated with RV end-diastolic volume, stroke volume, cardiac output, and mass prior to adjustment for LV measures. After adjustment for LV end-diastolic volume, greater percent emphysema was associated with greater RV end-diastolic volume (+1.5 mL, P = .03) among current smokers, smaller RV end-diastolic volume (−0.8 mL, P = .02) among former smokers, and similar changes among never smokers. Conclusions: Percent emphysema was associated with smaller RV volumes and lower mass. The relationship of emphysema to cardiac function is complex but likely involves increased pulmonary vascular resistance, predominantly with reduced cardiac output, pulmonary hyperinflation, and accelerated cardiopulmonary aging.

Aims The US Food and Drug Administration must consider whether to ban the use of menthol in cigarettes. This study examines how current smokers might respond to such a ban on menthol cigarettes. Design Convenience sample of adolescent and adult smokers recruited from an online survey panel. Setting United States, 2010. Participants 471 adolescent and adult current cigarette smokers. Measurements Respondents were asked a series of questions about how they might react if menthol cigarettes were banned. In addition, participants completed a simulation purchase task to estimate the demand for menthol and nonmenthol cigarettes across a range of prices. Findings Overall, 36% respondents said they always or usually smoked menthol cigarettes. When asked how they might respond to a ban on menthol cigarettes, 35% of current menthol smokers said they would stop smoking, and 25% said they would ‘find a way to buy a menthol brand.’ Those who reported they might quit tended to have greater current intentions to quit (OR=4.46), while those who reported they might seek illicit menthol cigarettes were far less likely to report current intentions to quit (OR = 0.06). Estimates for individual demand elasticity for preferred cigarette type were similar for menthol (α = .0051) and nonmenthol (α = .0049) smokers. Demand elasticity and peak consumption were related to usual cigarette type and cigarettes smoked per day, but did not appear to differ by race, gender, or age. Conclusions Preliminary evidence suggests that a significant minority of smokers of menthol cigarettes in the US would try to stop smoking altogether if such cigarettes were banned. PMID:22471735

This study applies qualitative research methods to explore perspectives on cessation among smokers/former smokers recruited from an area of Northern Appalachia. Six focus groups, stratified by age group (18–39 years old and 40 years and older), were conducted among participants (n=54) recruited from community settings. Participants described varied interest in and challenges with quitting smoking. Smokers 40 years and older more readily endorsed the health risks of smoking and had greater interest in quitting assistance. Participants expressed frustration with the U.S. government for allowing a harmful product (e.g., cigarettes) to be promoted with minimal regulation. Use of social media was robust among both age groups; participants expressed limited interest in various social media/technology platforms for promoting smoking cessation. Findings from this understudied area of northern Appalachia reflect the heterogeneity of this region and contribute novel information about the beliefs, attitudes, and experiences of current and formers smokers with regard to cessation.

To evaluate the effect of an antismoking advertisement on young people's perceptions of smoking in movies and their intention to smoke. 3091 cinema patrons aged 12-24 years in three Australian states; 18.6% of the sample (n = 575) were current smokers. Quasi-experimental study of patrons, surveyed after having viewed a movie. The control group was surveyed in week 1, and the intervention group in weeks 2 and 3. Before seeing the movie in weeks 2 and 3, a 30 s antismoking advertisement was shown, shot in the style of a movie trailer that warned patrons not to be sucked in by the smoking in the movie they were about to see. Attitude of current smokers and non-smokers to smoking in the movies; intention of current smokers and non-smokers to smoke in 12 months. Among non-smokers, 47.8% of the intervention subjects thought that the smoking in the viewed movie was not OK compared with 43.8% of the control subjects (p = 0.04). However, there was no significant difference among smokers in the intervention (16.5%) and control (14.5%) groups (p = 0.4). A higher percentage of smokers in the intervention group indicated that they were likely to be smoking in 12 months time (38.6%) than smokers in the control group (25.6%; p<0.001). For non-smokers, there was no significant difference in smoking intentions between groups, with 1.2% of intervention subjects and 1.6% of controls saying that they would probably be smoking in 12 months time (p = 0.54). This real-world study suggests that placing an antismoking advertisement before movies containing smoking scenes can help to immunise non-smokers against the influences of film stars' smoking. Caution must be exercised in the type of advertisement screened as some types of advertising may reinforce smokers' intentions to smoke.

To examine the influence of smoking history on the diagnosis and other tumor characteristics of upper tract urothelial carcinoma in Japan. A total of 1509 patients with upper tract urothelial carcinoma who were diagnosed in 2005 from 348 Japanese institutions were registered using the multi-institutional national database of the Japanese Urological Association and included in this analysis. Clinical data of the patients were collected in 2011. The associations between the patients' self-reported smoking history and their age at the diagnosis of upper tract urothelial carcinoma, sex, pathological T stage and tumor grade were analyzed. The mean age at the diagnosis of upper tract urothelial carcinoma was approximately 5 years earlier for the 238 current smokers than for the 618 current non-smokers (P < 0.0001). Similar associations between smoking and the early diagnosis of upper tract urothelial carcinoma were shown in the sex subgroups and in subgroups stratified by pathological T stages. Among the current smokers, the age at diagnosis for the smoking ≥ 20 cigarettes per day group was 6.5 years lower than that of the < 20 cigarettes per day group, which was significantly different (P < 0.0001). Current smoking is a significant risk factor for the earlier diagnosis of upper tract urothelial carcinoma. The finding is important from the perspective of both healthcare and medical economies. © 2015 The Japanese Urological Association.

To investigate prospectively the associations of Dietary Inflammatory Index (DII) and Mediterranean Diet Score (MDS) with lung cancer. We used data from men and women aged 40-69 years at recruitment in 1990-1994, who were participants in the Melbourne Collaborative Cohort Study (n = 35,303). A total of 403 incident lung cancer cases were identified over an average 18-year follow-up. Hazard ratios (HR) were estimated using Cox regression, adjusting for smoking status and other risk factors, with age as the time metric. An inverse correlation was observed between the DII and MDS (ρ = -0.45), consistent with a higher DII being pro-inflammatory and less 'healthy,' while a high MDS reflects a 'healthier' diet. The DII was positively associated with risk of lung cancer in current smokers [HRQ4 vs Q1 = 1.70 (1.02, 2.82); Ptrend = 0.008] (p interaction between DII quartiles and smoking status = 0.03). The MDS was inversely associated with lung cancer risk overall [HR7-9 vs 0-3 = 0.64 (0.45, 0.90); Ptrend = 0.005] and for current smokers (HR7-9 vs 0-3 = 0.38 (0.19, 0.75); Ptrend = 0.005) (p interaction between MDS categories and smoking status = 0.31). The MDS showed an inverse association with lung cancer risk, especially for current smokers. A high DII, indicating a more pro-inflammatory diet, was associated with risk of lung cancer only for current smokers. A healthy diet may reduce the risk of lung cancer, especially in smokers.

Introduction: Absolute and comparative risk perceptions, worry, perceived severity, perceived benefits, and self-efficacy are important theoretical determinants of tobacco use, but no measures have been validated to ensure the discriminant validity as well as test-retest reliability of these measures in the tobacco context. The purpose of the current study is to examine the reliability and factor structure of a measure assessing smoking-related health cognitions and emotions in a national sample of current and former heavy smokers in the National Lung Screening Trial. Methods: A sub-study of the National Lung Screening Trial assessed current and former smokers’ (age 55–74; N = 4379) self-reported health cognitions and emotions at trial enrollment and at 12-month follow-up. Items were derived from the Health Belief Model and Self-Regulation Model. Results: An exploratory factor analysis of baseline responses revealed a five-factor structure for former smokers (risk perceptions, worry, perceived severity, perceived benefits, and self-efficacy) and a six-factor structure for current smokers, such that absolute risk and comparative risk perceptions emerged as separate factors. A confirmatory factor analysis of 12-month follow-up responses revealed a good fit for the five latent constructs for former smokers and six latent constructs for current smokers. Longitudinal stability of these constructs was also demonstrated. Conclusions: This is the first study to examine tobacco-related health cognition and emotional constructs over time in current and former heavy smokers undergoing lung screening. This study found that the theoretical constructs were stable across time and that the factor structure differed based on smoking status (current vs. former). PMID:25964503

It has been recognized that patients with non-small cell lung cancer who are lifelong never-smokers constitute a distinct clinical entity. The aim of this study was to assess clinical risk factors for survival among never-smokers with non-small cell lung cancer. All consecutive non-small cell lung cancer patients diagnosed (n = 285) between May 2005 and May 2009 were included. The clinical characteristics of never-smokers and ever-smokers (former and current) were compared using chi-squared or Student's t tests. Survival curves were calculated using the Kaplan-Meier method, and log-rank tests were used for survival comparisons. A Cox proportional hazards regression analysis was evaluated by adjusting for age (continuous variable), gender (female vs. male), smoking status (never- vs. ever-smoker), the Karnofsky Performance Status Scale (continuous variable), histological type (adenocarcinoma vs. non-adenocarcinoma), AJCC staging (early vs. advanced staging), and treatment (chemotherapy and/or radiotherapy vs. the best treatment support). Of the 285 non-small cell lung cancer patients, 56 patients were never-smokers. Univariate analyses indicated that the never-smoker patients were more likely to be female (68% vs. 32%) and have adenocarcinoma (70% vs. 51%). Overall median survival was 15.7 months (95% CI: 13.2 to 18.2). The never-smoker patients had a better survival rate than their counterpart, the ever-smokers. Never-smoker status, higher Karnofsky Performance Status, early staging, and treatment were independent and favorable prognostic factors for survival after adjusting for age, gender, and adenocarcinoma in multivariate analysis. Epidemiological differences exist between never- and ever-smokers with lung cancer. Overall survival among never-smokers was found to be higher and independent of gender and histological type.

Background Light and/or intermittent smokers have been the fastest growing segment of cigarette smokers in the U.S. over the past two decades. Defining their behavioral characteristics is a critical public health priority. Materials and Methods Our sample included 78,229 U.S. adults from three pooled contemporary population-based surveys: the 2012 NHIS, 2012 NSDUH, and 2011-2012 NHANES. We classified current smokers into four categories (light and intermittent [LITS], light-daily, heavier-intermittent and heavier-daily) and assessed smoking behaviors, illicit drug use, and mental health indicators using weighted analyses. Results Analyses associated smoking categories with nicotine dependence, age of smoking initiation, race/ethnicity and other demographic and behavioral factors. Compared to heavier-daily smokers, smokers who were LITS were most likely to have mild or no nicotine dependence (weighted odds ratio [OR] = 16.92, 95% confidence interval [CI] 13.10-21.85), to start smoking cigarettes regularly after age 21 (OR = 3.42, 95% CI 2.84-4.12), and to be Hispanic (OR = 5.38, 95% CI 4.38-6.61). Additional significant results were found for other categories of smokers. Conclusion Based on pooled data from three large national surveys, light and/or intermittent smokers differed in smoking, drug use and mental health behaviors from heavier-daily, former and never smokers. Notable differences by level of smoking frequency and intensity were observed for nicotine dependence, age of smoking initiation and race/ethnicity. Impact Our results may help focus preventive measures and policies for the growing number of light and/or intermittent smokers in the U.S. because smoking patterns vary by behavioral and socioeconomic factors.

At present, 70% of the world’s 1.1 billion smokers are in developing countries, with over 50% in Asia alone. The current study examined patterns of youth smoking in Thailand and Malaysia. Respondents were 2002 youths between the ages of 13 and 17 from Thailand (n = 1000) and Malaysia (n = 1002). Respondents were selected using a multistage cluster sampling design and surveyed between January 2005 and March 2005. Approximately 3% of youth between the ages of 13 and 17 were current smokers, with an additional 10% to 12% reporting experimental smoking. Males were between 7 and 15 times more likely to report smoking behavior than females. Less than 1% of females respondents in either country met the criteria for current smoking, and less than 5% met the criteria for experimental smoking. In contrast, more than 50% Thai males and approximately one- third of Malaysian males aged 17 met the criteria for either experimental or current smoking. PMID:19124313
Healthy Migrant Effect on Smoking Behavior Among Asian Immigrants in the United States.
Kuerban, Aliya
2016-02-01
Healthy migrant effect (HME) of immigrants has been evidenced in various heath aspects. However, few studies have explored the applicability of HME on Asian immigrants' health risk behavior-smoking. This study used three waves of Current Population Survey-Tobacco Use Supplement data, 1998-1999, 2005-2006, and 2010-2011, to compare the rates of being a current smoker among Asian immigrants and United States born citizens. Further, the odds ratios of gender, age, marital status, socioeconomic status, years of migration, and citizenship status on the likelihood of being a current smoker were examined. Across the three waves, Asian immigrants smoked at a much lower rate than their native-born counterparts. The gender gap of being a current smoker was much wider among Asian immigrants. The longer the Asian immigrants stayed in the United States, the more likely they were to become current smokers. These data confirmed the association of HME and Asian immigrants' smoking behavior, and also provided strong evidence of the importance of smoking prevention among Asian immigrants. This study also implied the possibility of a decline in the effectiveness of HME on Asian immigrants as the time they spent in the United States increased.
Smoking and depressive symptoms in a college population.

A number of studies have documented the relationship between smoking and depression in adolescent and adult populations. The purpose of this study was to examine the level of depressive symptoms among college-age smokers and to determine whether or not increases in cigarette use were associated with increases in the number of depressive symptoms. A non-experimental cross-sectional design was used. Of the random sample (N = 895), 28% were current smokers, and more than 26% of the total sample reported high levels of depressive symptoms. Current smokers were more likely to report an increased level of depressive symptoms than nonsmokers were. Correlates of depressive symptoms included grade point average, marijuana use, and increased work hours. When controlling for these variables, the number of days smoked was predictive of depressive symptoms. School nurses have an important role in preventing smoking and treating smokers, as well as in preparing adolescents for the transition to college where many begin smoking.

Isolated and Skeptical: Social Engagement and Trust in Information Sources Among Smokers
Blake, Kelly; Hesse, Bradford W.; Ackerson, Leland K.
2014-01-01
Our study compared indicators of social engagement and trust among current, former, and never smokers. Multinomial regression analyses of data from the 2005 U.S. Health Information National Trends Survey (n=5586) were conducted to identify independent associations between social engagement, trust in health information sources, and smoking status. Never smokers (odds ratio (OR)=2.08) and former smokers (OR=2.48) were significantly more likely to belong to community organizations than current smokers. Never (OR=4.59) and former smokers (OR=1.96) were more likely than current smokers to attend religious services. Never smokers (OR=1.38) were significantly more likely than current smokers to use the Internet. Former smokers (OR=1.41) were more likely than current smokers to be married. Compared to current smokers, never smokers were significantly more likely to trust health care professionals (OR=1.52) and less likely to trust the Internet (OR=0.59) for health information. Current smokers are less socially engaged and less trusting of information resources than non-smokers. PMID:21340632

Objective: To evaluate the effect of an anti-smoking advertisement on young women's perceptions of smoking in movies and their intention to smoke. Subjects/setting: 2038 females aged 12–17 years attending cinemas in New South Wales, Australia. Design/intervention: Quasi-experimental study of patrons, who were surveyed after having viewed a movie at their local cinema. The control group was surveyed during week 1 and the intervention group, during week 2. Before seeing the movie in week 2, a 30 second anti-smoking advertisement was shown, which featured a well known female actor drawing attention to the prevalence of smoking in movies. Outcomes: Attitude of current smokers and non-smokers to smoking in the movies; intention of current smokers and non-smokers to be smoking in 12 months time. Results: Among non-smokers, 48.2% of the intervention subjects thought that the smoking in the movie they viewed was "not OK" compared with 28.3% of the control subjects (p < 0.0001). However, there was no difference among smokers in the intervention (26.4%) and control (16.9%) groups (p = 0.28). A higher percentage of current smokers in the intervention group indicated they were unlikely to smoke in 12 months time (47.8%) than smokers in the control condition (31.9%) (p = 0.03). For non-smokers, there was no difference in smoking intentions between conditions, with 95% saying they would be unlikely to be smoking in 12 months time. Conclusions: This "real world" study suggests that placing an anti-smoking advertisement before movies containing smoking scenes can help to "immunise" young women against the influences of film stars smoking.

Recent reports highlighted the association between smoking and higher risk of postsurgical infections. The aim was to compare the incidence of prosthetic joint infection after primary total joint arthroplasty (TJA) according to smoking status. A prospective hospital registry-based cohort study was performed including all primary knee and hip TJAs performed between March 1996 and December 2013. Smoking status preoperatively was classified into never, former, and current smoker. Incidence rates and hazard ratios (HRs) for prosthetic joint infection according to smoking status were assessed within the first year and beyond. We included 8559 primary TJAs (mean age 69.5 years), and median follow-up was 67 months. There were 5722 never, 1315 former, and 1522 current smokers. Incidence rates of infection within the first year for never, former, and current smokers were, respectively, 4.7, 10.1, and 10.9 cases/1000 person-years, comparing ever vs never smokers, crude and adjusted HRs were 2.35 (95% confidence interval [CI] 1.39-3.98) and 1.8 (95% CI 1.04-3.2). Beyond the first year, crude and adjusted HRs were 1.37 (95% CI 0.78-2.39) and 1.12 (95% CI 0.61-2.04). Smoking increased the infection risk about 1.8 times after primary hip or knee TJA in both current and former smokers. Beyond the first year, the infection risk was similar to never smokers.

No study has reported the relationship between cotinine-verified and self-reported smoking status with metabolic syndrome (MetS). This study was performed to evaluate the relationship between urinary cotinine-verified and self-reported smoking status with MetS and determine the effects of unobserved smokers on MetS in Korean adults. A total of 116,094 individuals (66,875 men and 49,219 women) with mean age of 36.7 ± 6.8 years included in Kangbuk Samsung Health Study and Kangbuk Samsung Cohort Study between 2011 and 2013 who had urinary cotinine measurements were enrolled. Cotinine-verified current smoking was defined as urinary cotinine level of above 50 ng/mL. Unobserved smoking was defined as urinary cotinine level of above 50 ng/mL in self-reported never smokers. The overall prevalence rates of cotinine-verified current smokers and MetS were 22.9% and 10.5%, respectively. The misclassification rate to cotinine-verified current smokers among self-reported never smokers was 1.7%. A multivariate logistic regression model adjusted for variables with univariate relationship (model 1) showed that cotinine-verified current smokers significantly increased the odds ratio for MetS compared with cotinine-verified never smokers (odds ratio [95% confidence interval], 1.30 [1.23, 1.37]). Log-transformed cotinine levels were also associated with MetS (1.04 [1.03, 1.05]). However, the association was not significant in the previously mentioned model including the traditional 5 components of MetS (model 2). Unobserved smokers significantly increased the ORs for MetS in both model 1 (1.43 [1.23, 1.67]) and model 2 (1.57 [1.06, 2.33]). This study shows that unobserved smoking and cotinine-verified current smoking are associated with MetS but urinary cotinine could be 1 conditional factor that interacts with traditional MetS components.

We evaluated long-term incidence of cancer after myocardial infarction among current, former, and never smokers, and assessed whether reducing cigarette consumption is associated with decreased cancer risk. Consecutive patients aged ≤65 years discharged from 8 hospitals in central Israel after first myocardial infarction in 1992-1993 were followed for cancer and death. Extensive data including smoking habits were obtained at the index hospitalization and 4 time points during follow-up. Survival methods were applied to assess the hazard ratios (HRs) for cancer associated with smoking categories. Included in the study were 1486 cancer-free participants (mean age, 54 years; 81% men), among whom 787 were current smokers at baseline (average daily cigarette consumption = 29). Smokers were younger than nonsmokers and more likely to be male and of lower socioeconomic status. Over a median follow-up of 21.4 years, 273 (18.4%) patients developed cancer. Baseline smoking was associated with a ∼40% excess adjusted risk of cancer; ∼25% after accounting for death as a competing event. Considering changes in smoking during follow-up, the excess risk was confined to persistent smokers (adjusted HR 1.75; 95% confidence interval [CI], 1.22-2.50), whereas post- (HR 1.14; 95% CI, 0.80-1.62) and pre-myocardial infarction quitters (HR 1.02; 95% CI, 0.71-1.47) were comparable with never smokers. Among persistent smokers, each reduction of 10 cigarettes relative to pre-myocardial infarction consumption was associated with a ∼10% reduced adjusted risk. Among young survivors of first myocardial infarction followed-up longitudinally, smoking cessation is associated with lower risk of cancer. Reducing consumption among smokers may also be beneficial.

To examine the sociodemographic characteristics associated with smoke-free homes (SFHs) in NSW and specify high-risk groups with a low prevalence of household smoking restrictions. Data were drawn from the 1998 NSW Health Survey, a computer-assisted telephone interview survey of 17,494 randomly selected respondents aged > or = 16 years across NSW (response rate = 70%). Logistic regression analyses, stratified by smoking status, were used. Overall, 72% of adults reported having a SFH; 87% of never-smokers, 81% of ex- and 35% of current smokers. The highest percentages of SFHs were reported in households with young children (78%) and with older children (72%) or with adults only (72%). For smokers, SFHs were independently associated with the presence of young children (OR=3.8, 95% CI 3.1-4.7) compared with those who lived alone, but the odds of living in a SFH were only slightly increased for smokers living with older children (aged 6-15) and for those living with adults only (OR=1.9, OR=1.8 respectively). Speaking a language other than English at home, having more than 10 years' education, and being <35 years old were independently and positively associated with SFH. Being employed in smoke-free workplaces increased the likelihood of SFHs for both current and past smokers (OR=1.6, OR=1.2 respectively). Most NSW homes have restrictions on smoking inside, but more than half the households with children and at least one smoker adult are not smoke free. Interventions to shape parents' smoking behaviour around older children are warranted. Strategies need to address never-smokers in communities with high prevalence of smoking and adults with lower levels of education. A continued commitment to workplace smoking bans is important as they may affect household smoking restrictions.

Tobacco smoking is the leading cause of preventable morbidity and mortality in the United States, and smoking cessation has multiple health benefits. The purpose of this study was to assess cigarette smokers' perceived importance toward characteristics of tobacco cessation medications using a willingness-to-pay approach. Cross-sectional analysis of data from the 2008 HealthStyles survey, a mail-based probability sample of 5399 adults aged 18 years and older.Point estimates and 95% confidence intervals were calculated overall and by sociodemographic and smoking behavior characteristics. Multivariate Probit regression analysis was used to evaluate smokers' willingness to pay in relation to perceived importance of 3 cessation medication characteristics: convenience of use, over-the-counter availability, and efficiency to help quit. All models controlled for sociodemographic characteristics, smoking behavior characteristics, and US regional fixed effects. A total of 914 current cigarette smokers. Interest in quitting, interest in using cessation medications, and willingness to pay for 6 types of cessation medications. Approximately 68.4% of current cigarette smokers were interested in quitting. Among these individuals, 45.6% indicated that they were interested in using cessation medications, and of these, 47.3% indicated that they were willing to pay $150 or more out-of-pocket for these medications. Convenience of use and the effectiveness of these medications to help quit were positively associated with current smokers' willingness to pay for $300 or more (P < .05); however, no association was observed for over-the-counter availability. Self-reported exposure to telephone quitline advertisements was also positively associated with the willingness to pay. Approximately 68% of current smokers are interested in quitting, and about half of those smokers interested in quitting are also interested in using cessation medications. Convenience of use and the medication's effectiveness are important characteristics of cessation medication for smokers with quit intentions. Understanding preferences for these cessation medication characteristics may help inform smoking cessation efforts.

Background: Health warning labels on cigarette packages are among the most straightforward and important tools to communicate with smokers and various studies have illustrated their efficacy. Objectives: The current study aimed to investigate the opinions of male smokers in Mashhad city about the efficacy of health warning labels printed on cigarette packages on the smoking status of smokers. Patients and Methods: This cross-sectional descriptive study was conducted in 2013 using a questionnaire. The research population included the male smokers of Mashhad. The participants were selected from the customers referring to the newsstands for cigarettes. The obtained data were analyzed employing SPSS software Version 16, and the statistical tests including Kruskal-Wallis, Spearman, and correlation coefficient of Pearson, Chi Square, Mann-Whitney, and Bonferroni correction were used in this regard. Results: In this research, there were 500 participants with the average age of 25 years. The initiation age of smoking was eight years while the maximum age was reported as 45 years. Results of this research about the effect of these labels on decreasing cigarette consumption rate showed that almost half of the participants believed that these labels were ineffective for them (52.2%) and other smokers (53.8%).Furthermore, significant relationship was found between the age and opinion of the smokers about the influence of these labels on reducing their cigarette consumption (P < 0.001). Conclusions: To promote the effect of printed images on cigarette packages, it is recommended to consider the suitability of labels in the targeted culture. In addition, to be more effective consultation sites to quit smoking should be introduced under the images. PMID:24829777

AIM To investigate the association between smoking habits and surgical outcomes in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) (B-HCC) and hepatitis C virus (HCV)-related HCC (C-HCC) and clarify the clinicopathological features associated with smoking status in B-HCC and C-HCC patients. METHODS We retrospectively examined the cases of the 341 consecutive patients with viral-associated HCC (C-HCC, n = 273; B-HCC, n = 68) who underwent curative surgery for their primary lesion. We categorized smoking status at the time of surgery into never, ex- and current smoker. We analyzed the B-HCC and C-HCC groups’ clinicopathological features and surgical outcomes, i.e., disease-free survival (DFS), overall survival (OS), and disease-specific survival (DSS). Univariate and multivariate analyses were performed using a Cox proportional hazards regression model. We also performed subset analyses in both patient groups comparing the current smokers to the other patients. RESULTS The multivariate analysis in the C-HCC group revealed that current-smoker status was significantly correlated with both OS (P = 0.0039) and DSS (P = 0.0416). In the B-HCC patients, no significant correlation was observed between current-smoker status and DFS, OS, or DSS in the univariate or multivariate analyses. The subset analyses comparing the current smokers to the other patients in both the C-HCC and B-HCC groups revealed that the current smokers developed HCC at significantly younger ages than the other patients irrespective of viral infection status. CONCLUSION A smoking habit is significantly correlated with the overall and disease-specific survivals of patients with C-HCC. In contrast, the B-HCC patients showed a weak association between smoking status and surgical outcomes. PMID:29358882

To describe the population that reports to have visited tobacco points of sale (POS) in Argentina and their perception of tobacco advertising. We used data from the 2013 National Risk Factor Survey. We included 31 167 respondents (96% of the total) who attended a store that sells cigarettes in the previous 30 days. Overall, 54.1% (67.3% of current smokers, 55.1% of former smokers and 49% of non smokers) referred having seen tobacco advertising at the POS. Males (OR=1.2) and current smokers (OR=1.9 vs. non smokers) were more likely to report having seen tobacco advertising at the POS. Those who were exposed to second hand smoke in bars and restaurants (OR=1.2) were also more likely to have seen advertising. We found that younger people (age 18 - 24) were more likely to be exposed (OR=2.8 vs older than 65). Among smokers, those who referred to have seen the advertising were more likely to have tried to quit smoking during the previous year. It is important to regulate advertising at the POS to limit exposure, particularly among young people.

Current tobacco use treatment approaches require smokers to request treatment or depend on the provider to initiate smoking cessation care and are therefore reactive. Most smokers do not receive evidence-based treatments for tobacco use that include both behavioral counseling and pharmacotherapy. To assess the effect of a proactive, population-based tobacco cessation care model on use of evidence-based tobacco cessation treatments and on population-level smoking cessation rates (ie, abstinence among all smokers including those who use and do not use treatment) compared with usual care among a diverse population of current smokers. The Veterans Victory Over Tobacco Study, a pragmatic randomized clinical trial involving a population-based registry of current smokers aged 18 to 80 years. A total of 6400 current smokers, identified using the Department of Veterans Affairs (VA) electronic medical record, were randomized prior to contact to evaluate both the reach and effectiveness of the proactive care intervention. Current smokers were randomized to usual care or proactive care. Proactive care combined (1) proactive outreach and (2) offer of choice of smoking cessation services (telephone or in-person). Proactive outreach included mailed invitations followed by telephone outreach to motivate smokers to seek treatment with choice of services. The primary outcome was 6-month prolonged smoking abstinence at 1 year and was assessed by a follow-up survey among all current smokers regardless of interest in quitting or treatment utilization. A total of 5123 participants were included in the primary analysis. The follow-up survey response rate was 66%. The population-level, 6-month prolonged smoking abstinence rate at 1 year was 13.5% for proactive care compared with 10.9% for usual care (P = .02). Logistic regression mixed model analysis showed a significant effect of the proactive care intervention on 6-month prolonged abstinence (odds ratio [OR], 1.27 [95% CI, 1.03-1.57]). In analyses accounting for nonresponse using likelihood-based not-missing-at-random models, the effect of proactive care on 6-month prolonged abstinence persisted (OR, 1.33 [95% CI, 1.17-1.51]). Proactive, population-based tobacco cessation care using proactive outreach to connect smokers to evidence-based telephone or in-person smoking cessation services is effective for increasing long-term population-level cessation rates. clinicaltrials.gov Identifier: NCT00608426.

Recently, the US Institute of Medicine has proposed that raising the minimum age for tobacco purchasing/sales to 21 years would likely lead to reductions in smoking behavior among young people. Surprisingly few studies, however, have assessed the potential impacts of minimum-age tobacco restrictions on youth smoking. To estimate the impacts of Canadian minimum age for tobacco sales (MATS) laws on youth smoking behaviour. A regression-discontinuity design, using seven merged cycles of the Canadian Community Health Survey, 2000-2014. Survey respondents aged 14-22 years (n=98 320). Current Canadian MATS laws are 18 years in Alberta, Saskatchewan, Manitoba, Quebec, the Yukon and Northwest Territories, and 19 years of age in the rest of the country. Current, occasional and daily smoking status; smoking frequency and intensity; and average monthly cigarette consumption. In comparison to age groups slightly younger than the MATS, those just older had significant and abrupt increases immediately after the MATS in the prevalence of current smokers (absolute increase: 2.71%; 95% CI 0.70% to 4.80%; P=0.009) and daily smokers (absolute increase: 2.43%; 95% CI 0.74% to 4.12%; P=0.005). Average past-month cigarette consumption within age groups increased immediately following the MATS by 18% (95% CI 3% to 39%; P=0.02). There was no evidence of significant increases in smoking intensity for daily or occasional smokers after release from MATS restrictions. The study provides relevant evidence supporting the effectiveness of Canadian MATS laws for limiting smoking among tobacco-restricted youth. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Flavour additives in cigarettes and little cigars and cigarillos (LCCs), which influence smokers' risk perceptions, may reinforce dual flavoured tobacco use. We examined the association among mentholated cigarette use, risk perceptions for flavour additives in LCCs and flavoured LCC smoking behaviour. Data from a national probability sample of 964 young and middle-aged adult current cigarette smokers were analysed. Multinomial logistic regression models examined the relationship among mentholated cigarette smoking, risk perceptions and current flavoured LCC use for the analytic sample and gender and race/ethnicity. Daily menthol cigarette smokers, compared to occasional, non-menthol smokers, had increased odds of flavoured LCC smoking (OR=1.75, 95% CI 1.02 to 2.98). This relationship was found for males, blacks/African-Americans and Hispanics/Latinos (p<0.05). Positive perceptions of menthol-flavoured additives in LCCs was associated with increased odds of flavoured LCC use among the analytic sample, males and blacks/African-Americans (p<0.05). Positive perceptions for clove-flavoured, spice-flavoured and alcohol-flavoured additives were also associated with flavoured LCC use among the analytic sample (p<0.05). Use of menthol-flavoured cigarettes and positive perceptions about menthol-flavoured and other flavour additives in LCCs may contribute to dual use with flavoured LCCs among adult cigarette smokers, specifically those from vulnerable populations.

To explore how and why tobacco smokers and recent quitters in NSW use e-cigarettes, as well as common places of purchase. The Cancer Institute Tobacco Tracking Survey is a serial cross-sectional telephone survey, with 40 interviews in NSW each week. 2966 tobacco smokers and recent quitters (in the past 12 months) interviewed January 2014 - June 2015. Current e-cigarette use; reasons for using; places of purchase. 9% of the sample reported currently using e-cigarettes; the rate was highest among 18-29-year-old people (16%). Infrequent use (less than weekly; 57%) was more common than frequent use (at least weekly; 43%). Frequent use was more likely among older adults (55 years and older v 18-29 years: adjusted odds ratio [aOR], 4.43; P = 0.002) and less likely among current tobacco smokers (v recent quitters: aOR, 0.38, P = 0.020). The most common reasons for using e-cigarettes by those over 30 years of age was "to help me quit" (42%) and to "cut down" smoking (35%); for younger adults it was "because they are not as bad for your health as cigarettes" (25%). Common places of purchase were the internet (29%) and tobacconists (27%). Although use of e-cigarettes by tobacco smokers in NSW remains low, some are using e-cigarettes in attempts to reduce tobacco-related harm. Physicians and public health campaigners should inform smokers about the risks associated with dual e-cigarette and tobacco use, advise interested quitters that e-cigarettes are currently unregulated as cessation aids, and continue to provide evidence-based recommendations and cessation services to smokers wanting to quit.

Smoking-related respiratory diseases are a major cause of morbidity and mortality. However, the relationship between smoking and respiratory disease has not been well-studied among ethnic minorities in general and among women in particular. The objective of this cross-sectional study was to evaluate the risk of airflow obstruction and to assess lung function among Hispanic and non-Hispanic White (NHW) female smokers in a New Mexico cohort. Participants completed a questionnaire detailing smoking history and underwent spirometry testing. Outcomes studied included airflow obstruction, selected lung function parameters, and chronic mucus hyper-secretion. Chi square, logistic, and linear regression techniques were utilized. Of the 1,433 eligible women participants, 248 (17.3%) were Hispanic; and 319 had airflow obstruction (22.3%). Hispanic smokers were more likely to be current smokers, and report lower pack-years of smoking, compared to NHW smokers (p < 0.05 for all analyses). Further, Hispanic smokers were at a reduced risk of airflow obstruction compared to NHW smokers, with an O.R. of 0.51, 95% C.I. 0.34, 0.78 (p = 0.002) after adjustment for age, BMI, pack-years and duration of smoking, and current smoking status. Following adjustment for covariates, Hispanic smokers also had a higher mean absolute and percent predicted post-bronchodilator FEV(1)/FVC ratio, as well as higher mean percent predicted FEV(1) (p < 0.05 for all analyses). Hispanic female smokers in this New Mexico-based cohort had lower risk of airflow obstruction and better lung function than NHW female smokers. Further, smoking history did not completely explain these associations.

Lung cancer has become a leading cause of death among people living with human immunodeficiency virus (HIV) (PLWH). Over 40% of PLWH in the United States smoke cigarettes; HIV independently increases the risk of lung cancer. To project cumulative lung cancer mortality by smoking exposure among PLWH in care. Using a validated microsimulation model of HIV, we applied standard demographic data and recent HIV/AIDS epidemiology statistics with specific details on smoking exposure, combining smoking status (current, former, or never) and intensity (heavy, moderate, or light). We stratified reported mortality rates attributable to lung cancer and other non-AIDS-related causes by smoking exposure and accounted for an HIV-conferred independent risk of lung cancer. Lung cancer mortality risk ratios (vs never smokers) for male and female current moderate smokers were 23.6 and 24.2, respectively, and for those who quit smoking at age 40 years were 4.3 and 4.5. In sensitivity analyses, we accounted for nonadherence to antiretroviral therapy (ART) and for a range of HIV-conferred risks of death from lung cancer and from other non-AIDS-related diseases (eg, cardiovascular disease). Cumulative lung cancer mortality by age 80 years (stratified by sex, age at entry to HIV care, and smoking exposure); total expected lung cancer deaths, accounting for nonadherence to ART. Among 40-year-old men with HIV, estimated cumulative lung cancer mortality for heavy, moderate, and light smokers who continued to smoke was 28.9%, 23.0%, and 18.8%, respectively; for those who quit smoking at age 40 years, it was 7.9%, 6.1%, and 4.3%; and for never smokers, it was 1.6%. Among women, the corresponding mortality for current smokers was 27.8%, 20.9%, and 16.6%; for former smokers, it was 7.5%, 5.2%, and 3.7%; and for never smokers, it was 1.2%. ART-adherent individuals who continued to smoke were 6 to 13 times more likely to die from lung cancer than from traditional AIDS-related causes, depending on sex and smoking intensity. Due to greater AIDS-related mortality risks, individuals with incomplete ART adherence had higher overall mortality but lower lung cancer mortality. Applying model projections to the approximately 644 200 PLWH aged 20 to 64 in care in the United States, 59 900 (9.3%) are expected to die from lung cancer if smoking habits do not change. Those PLWH who adhere to ART but smoke are substantially more likely to die from lung cancer than from AIDS-related causes.

Risk factors for chronic cough in the general population have not been described systematically. We identified and ranked chronic cough risk factors at the individual and community level using data from 14,669 individuals from the Copenhagen General Population Study. Severity of chronic cough was assessed using the Leicester Cough Questionnaire (LCQ). We ranked chronic cough risk factors based on magnitude of age-adjusted ORs at the individual level and of the population attributable risks (PARs) at the community level. Prevalence of chronic cough in the general population was 4% overall and 3% in never smokers, 4% in former smokers, and 8% in current smokers. Median score of the LCQ was 5.8 (25th-75th percentile, 5.0-6.3) for physical domain, 5.6 (25th-75th percentile, 4.6-6.3) for psychologic domain, 6.3 (25th-75th percentile, 5.5-6.8) for social domain, and 17.3 (25th- 75th percentile, 15.4-18.9) in total. At the level of the individual, age-adjusted ORs for the three top-ranked risk factors were 5.0 (95% CI, 1.4-18) for bronchiectasis, 2.6 (95% CI, 1.7-3.9) for asthma and 2.3 (95% CI, 1.5-3.4) for gastroesophageal reflux disease in never smokers, 7.1 (95% CI, 2.6-20) for bronchiectasis, 3.1 (95% CI, 2.2-4.4) for asthma and 2.2 (95% CI, 1.5-3.2) for occupational exposure to dust/fumes in former smokers, and 1.9 (95% CI, 1.3-2.9) for airflow limitation in current smokers. At the level of the community, the three top-ranked risk factors were female sex (PAR, 19%), asthma (PAR, 10%), and gastroesophageal reflux disease (PAR, 8%) in never smokers; abdominal obesity (PAR, 20%), low income (PAR, 20%), and asthma (PAR, 13%) in former smokers; and airflow limitation (PAR, 23%) in current smokers. Risk factors for chronic cough differ at the level of the individual and community, and by smoking status. Strategies to prevent and treat modifiable chronic cough risk factors should be tailored accordingly. Copyright © 2017 American College of Chest Physicians. Published by Elsevier Inc.

This study was conducted to investigate the relationship of active and passive smoking with occupational injury among manual workers. Data from the 2011 Korean Working Conditions Survey were analyzed for 12,507 manual workers aged ≥15 yr. Overall, 60.4% of men and 5.8% of women were current smokers. The prevalence of injury was higher among never smokers who were exposed to secondhand smoke (SHS) (7.7% in men and 8.1% in women) than current smokers (4.2% in men and 4.1% in women). After controlling for potential confounders, in men, compared to those who never smoked and were not exposed to SHS, people who never smoked and were exposed to SHS (adjusted odds ratio (aOR)=3.7, 2.2-6.4) and current smokers (aOR=2.5, 1.6-3.8) were more likely to experience injury. Among women, the aORs of occupational injury were 8.4 (4.2-16.7) for never smoking women with occasional exposure to SHS and 3.5 (95% CI: 1.4-8.7) for current smokers, in comparison to never smoking women who were never exposed to SHS at work (reference group). The present study suggests that exposure to SHS is a possible risk factor of occupational injury for never smoking men and women.

Background The purpose of this study was to assess the relationship of smoking duration with respiratory symptoms and history of chronic obstructive pulmonary disease (COPD) in the South Carolina Behavioral Risk Factor Surveillance System survey in 2012. Methods Data from 4,135 adults aged ≥45 years with a smoking history were analyzed using multivariable logistic regression that accounted for sex, age, race/ethnicity, education, and current smoking status, as well as the complex sampling design. Results The distribution of smoking duration ranged from 19.2% (1–9 years) to 36.2% (≥30 years). Among 1,454 respondents who had smoked for ≥30 years, 58.3% were current smokers, 25.0% had frequent productive cough, 11.2% had frequent shortness of breath, 16.7% strongly agreed that shortness of breath affected physical activity, and 25.6% had been diagnosed with COPD. Prevalence of COPD and each respiratory symptom was lower among former smokers who quit ≥10 years earlier compared with current smokers. Smoking duration had a linear relationship with COPD (P<0.001) and all three respiratory symptoms (P<0.001) after adjusting for smoking status and other covariates. While COPD prevalence increased with prolonged smoking duration in both men and women, women had a higher age-adjusted prevalence of COPD in the 1–9 years, 20–29 years, and ≥30 years duration periods. Conclusion These state population data confirm that prolonged tobacco use is associated with respiratory symptoms and COPD after controlling for current smoking behavior. PMID:26229460

Cigarette smoking is a behavior, which is influenced by genetic, demographic, and psychological factors. A large body of research has examined the association of cigarette smoking variables with individual differences in personality traits. The aim of the current study was to replicate the findings of higher self-reported impulsivity in smokers compared with never-smokers in a German sample using Eysenck´s construct of impulsivity. Furthermore, it was intended to further the knowledge about associations between different self-reported impulsivity components and different smoking variables. We used the Impulsiveness-Venturesomeness-Empathy questionnaire (I7) to measure self-reported impulsiveness and venturesomeness and the Temperament and Character Inventory (TCI) to measure novelty seeking (NS) in a sample of 82 nicotine-dependent smokers and 119 never-smokers. Smokers scored higher on impulsiveness, venturesomeness, and NS than never-smokers independent of age, gender, and years of education. We found a significant association between venturesomeness, impulsiveness and smoking status in daily smokers. In summary, this study provides evidence that impulsiveness and venturesomeness as well as the novelty-seeking subscale extravagance are significantly associated with smoking status in a German sample of female and male smokers compared with never-smokers.

Objectives To investigate whether associations of smoking with depression and anxiety are likely to be causal, using a Mendelian randomisation approach. Design Mendelian randomisation meta-analyses using a genetic variant (rs16969968/rs1051730) as a proxy for smoking heaviness, and observational meta-analyses of the associations of smoking status and smoking heaviness with depression, anxiety and psychological distress. Participants Current, former and never smokers of European ancestry aged ≥16 years from 25 studies in the Consortium for Causal Analysis Research in Tobacco and Alcohol (CARTA). Primary outcome measures Binary definitions of depression, anxiety and psychological distress assessed by clinical interview, symptom scales or self-reported recall of clinician diagnosis. Results The analytic sample included up to 58 176 never smokers, 37 428 former smokers and 32 028 current smokers (total N=127 632). In observational analyses, current smokers had 1.85 times greater odds of depression (95% CI 1.65 to 2.07), 1.71 times greater odds of anxiety (95% CI 1.54 to 1.90) and 1.69 times greater odds of psychological distress (95% CI 1.56 to 1.83) than never smokers. Former smokers also had greater odds of depression, anxiety and psychological distress than never smokers. There was evidence for positive associations of smoking heaviness with depression, anxiety and psychological distress (ORs per cigarette per day: 1.03 (95% CI 1.02 to 1.04), 1.03 (95% CI 1.02 to 1.04) and 1.02 (95% CI 1.02 to 1.03) respectively). In Mendelian randomisation analyses, there was no strong evidence that the minor allele of rs16969968/rs1051730 was associated with depression (OR=1.00, 95% CI 0.95 to 1.05), anxiety (OR=1.02, 95% CI 0.97 to 1.07) or psychological distress (OR=1.02, 95% CI 0.98 to 1.06) in current smokers. Results were similar for former smokers. Conclusions Findings from Mendelian randomisation analyses do not support a causal role of smoking heaviness in the development of depression and anxiety.

To examine how the relative size of six groups of male ever snus users (current and former users of snus who were current, former or never cigarette smokers) varied over time in Norway, and how these groups differ with regard to important measures of tobacco behaviour. Repeated cross-sectional nationally representative surveys of tobacco use. The association between survey year and the six categories of ever snus use was examined using cross-tabulation and multinomial logistic regression. Differences in tobacco behaviour across snus use categories were examined using logistic and ordinary least squares (OLS) regression. Norway, 2003-15. A total of 2067 males aged 15-79 years. The categories of ever snus use represented all six combinations of cigarette smoking (current, former or never) among current and former users of snus. The variables measuring tobacco behaviour were: order of product uptake (snus or cigarettes first), mean cigarette consumption, reduction from daily to occasional smoking, intention to quit cigarettes, future smoking identity and use of snus in latest quit attempt. During the period 2003-15, the relative share of current snus users who had never smoked, and current snus users who were former smokers, increased. The share of dual users, and smokers who were former snus users, decreased. Among men who reported life-time experience with both products, a large majority had initiated their tobacco use with cigarettes. The average number of cigarettes smoked weekly was lower among dual users compared with current smokers who were former snus users or had never used snus. During the period 2003-15 in Norway, which has a mature snus market, even though smoking has declined and the relative size of the category of never-smokers among male users of snus has increased, the majority of snus users are still former or current smokers. © 2016 The Authors.

This paper identifies predictors of trial and current use, and reasons for trying and ceasing use of electronic cigarettes (e-cigarettes) among young adults, with particular attention to former and never smokers. Data are from a mail survey of a population-based sample of adults aged 18 to 35 (N = 4740) in three U.S. metropolitan areas. Survey items assessed trial and use of e-cigarettes, cigarette smoking status, and reasons for trial and for ceasing use of e-cigarettes. Almost 23% reported trial of e-cigarettes, and 8.4% reported using them in the past month. Current smokers were much more likely to have tried e-cigarettes (70.2%) than both former (32.3%) and never smokers (7.6%; p < 0.001) and to have used them in the past month (30.8%, 10.1%, 2.0% respectively; p < 0.001). Smoking status and scores on sensation seeking were significant independent predictors of both trial and current use of e-cigarettes. Never-smokers cite curiosity as the reason for trying e-cigarettes and also that their friends used them. The most frequent reason for ceasing use among never and former smokers was health concerns. For virtually none of them were e-cigarettes their first exposure to nicotine. PMID:26694438

The aim of our study is; to assess the approach of smokers to tobacco law, examine changes in their smoking related behaviors after the new law and determine the factors associated with these changes. Data collected by questionnaire including 30 question. We applied the questionnaire to 1509 current smokers, and ex-smokers who quitted smoking after the law. SPSS packet programme was used for analyses. Participants consisted of 419 (28.0%) female, 1090 (72.0%) male with an average age of 33.6 ± 10.5 years. Although 80% of them knew that passive smoking is harmful to non-smokers, rate of smoking at home and in the car were very high. 869 (58.0%) of participants supported the law. 87 (5.8%) smokers quitted smoking after the law, 316 (20.9%) reduced. While health problems (37.3%) were the most frequent reason for quitting, restriction of smoking area had the most effect to reduce (54.2%). We satisfied that; the new tobacco law encouraged smokers to quit smoking. In addition, the majority of smokers supported the law.

E-cigarette use among adolescents has increased significantly in recent years, but it remains unclear whether cigarette smoking behaviors and intentions differ among current (i.e., 30-day) non-users, only e-cigarette users, only cigarette smokers, and dual users. A nationally representative sample of 4385 U.S. high school seniors (modal age 18 years) were surveyed during the spring of their senior year via self-administered questionnaires in 2014. An estimated 9.6% of U.S. high school seniors reported current (30-day) e-cigarette use only, 6.3% reported current cigarette smoking only, and 7.2% reported current dual use of e-cigarettes and cigarette smoking. There were no significant differences between current only cigarette smokers and dual users in the odds of early onset of cigarette smoking, daily cigarette smoking, future cigarette smoking intentions, friends’ cigarette smoking behaviors, attempts to quit cigarette smoking, or the inability to quit cigarette smoking. Adolescents who only used e-cigarettes had higher odds of cigarette smoking behaviors and intentions than current non-users, including intentions for future cigarette smoking in the next 5 years (AOR = 2.57, 95% CI: 1.21—5.24). Dual users and only cigarette smokers had higher odds of cigarette smoking behaviors and intentions than non-users or only e-cigarette users. Adolescents who engage in current dual use appear to have cigarette smoking behaviors and intentions that more closely resemble cigarette smokers than e-cigarette users. Adolescents who only use e-cigarettes have higher intentions to engage in cigarette smoking in the future relative to their peers who do not engage in e-cigarette use or cigarette smoking.

Objective To evaluate the effect of an antismoking advertisement on young people's perceptions of smoking in movies and their intention to smoke. Subjects/setting 3091 cinema patrons aged 12–24 years in three Australian states; 18.6% of the sample (n = 575) were current smokers. Design/intervention Quasi‐experimental study of patrons, surveyed after having viewed a movie. The control group was surveyed in week 1, and the intervention group in weeks 2 and 3. Before seeing the movie in weeks 2 and 3, a 30 s antismoking advertisement was shown, shot in the style of a movie trailer that warned patrons not to be sucked in by the smoking in the movie they were about to see. Outcomes Attitude of current smokers and non‐smokers to smoking in the movies; intention of current smokers and non‐smokers to smoke in 12 months. Results Among non‐smokers, 47.8% of the intervention subjects thought that the smoking in the viewed movie was not OK compared with 43.8% of the control subjects (p = 0.04). However, there was no significant difference among smokers in the intervention (16.5%) and control (14.5%) groups (p = 0.4). A higher percentage of smokers in the intervention group indicated that they were likely to be smoking in 12 months time (38.6%) than smokers in the control group (25.6%; p<0.001). For non‐smokers, there was no significant difference in smoking intentions between groups, with 1.2% of intervention subjects and 1.6% of controls saying that they would probably be smoking in 12 months time (p = 0.54). Conclusions This real‐world study suggests that placing an antismoking advertisement before movies containing smoking scenes can help to immunise non‐smokers against the influences of film stars' smoking. Caution must be exercised in the type of advertisement screened as some types of advertising may reinforce smokers' intentions to smoke. PMID:17565137

Background Menthol can mask the harshness and taste of tobacco, making menthol cigarettes easier to use and increasing their appeal among vulnerable populations. The tobacco industry has targeted youth, women, and racial minorities with menthol cigarettes, and these groups smoke menthol cigarettes at higher rates. The tobacco industry has also targeted the lesbian, gay, bisexual, and transgender (LGBT) communities with tobacco product marketing. Purpose To assess current menthol cigarette smoking by sexual orientation among a nationally representative sample of U.S. adults. Methods Data were obtained from the 2009–2010 National Adult Tobacco Survey, a national landline and cellular telephone survey of non-institutionalized U.S. adults aged ≥18 years, to compare current menthol cigarette smoking between LGBT (n=2,431) and heterosexual/straight (n=110,841) adults. Data were analyzed during January–April 2014 using descriptive statistics and logistic regression adjusted for sex, age, race, and educational attainment. Results Among all current cigarette smokers, 29.6% reported usually smoking menthol cigarettes in the past 30 days. Menthol use was significantly higher among LGBT smokers, with 36.3% reporting that the cigarettes they usually smoked were menthol compared to 29.3% of heterosexual/straight smokers (p<0.05); this difference was particularly prominent among LGBT females (42.9%) compared to heterosexual/straight women (32.4%) (p<0.05). Following adjustment, LGBT smokers had greater odds of usually smoking menthol cigarettes than heterosexual/straight smokers (OR=1.31, 95% CI=1.09, 1.57). Conclusions These findings suggest that efforts to reduce menthol cigarette use may have the potential to reduce tobacco use and tobacco-related disease and death among LGBT adults. PMID:25245795
Effects of wages on smoking decisions of current and past smokers.

We used longitudinal data and instrumental variables (IVs) in a prospective design to test for the causal effects of wages on smoking prevalence among current and past smokers. Nationally representative U.S. data were drawn from the 1999-2009 waves of the Panel Study of Income Dynamics. Our overall sample was restricted to full time employed persons, aged 21-65 years. We excluded part time workers and youths because smoking and wage correlations would be complicated by labor supply decisions. We excluded adult never smokers because people rarely begin smoking after the age of 20 years. IVs were created with state-level minimum wages and unionization rates. We analyzed subsamples of men, women, the less educated, the more educated, quitters, and backsliders. Validity and strength of instruments within the IV analysis were conducted with the Sargan-Hansen J statistic and F tests. We found some evidence that low wages lead to more smoking in the overall sample and substantial evidence for men, persons with high school educations or less (<13 years of schooling), and quitters. Results indicated that 10% increases in wages lead to 5.5 and 4.6 percentage point decreases in smoking for men and the less educated; they also increased the average chance of quitting among base-year smokers from 17.0% to 20.4%. Statistical tests suggested that IVs were strong and valid in most samples. Subjects' other family income, including spouses' wages, was entered as a control variable. Increases in an individual's wages, independent of other income, decreased the prevalence of smoking among current and past smokers. Copyright © 2015 Elsevier Inc. All rights reserved.

There are well-documented inverse relationships between smoking and smoking cessation with measures of socioeconomic status. This study used nationally representative data to examine unaided quit attempts and their sociodemographic determinants among daily current and former smokers who made a quit attempt in the last 12 months. We used data from the 2010-2011 Tobacco Use Supplement to the Current Population Survey. We limited the analysis to current daily smokers who made a quit attempt in the past year and former smokers who were daily smokers 1 year prior to the survey (N = 8201). Nearly 62% (n = 5078) of the sample made an unaided quit attempt. Adjusted results indicated unaided quit attempts were more likely among males compared to females (P < .001), younger age groups compared to older age groups (P < .001), non-Hispanic blacks compared to non-Hispanic whites (P < .001), among people with lower income compared to people with higher income (P < .001), and among people with lower nicotine dependence compared to those with higher nicotine dependence (P < .001). Most quit attempts were unaided and there were significant sociodemographic disparities in unaided quit attempts. Considering that cessation aids enhance the likelihood of quitting, policies and programs should target populations which are more likely to attempt quitting without an aid and encourage them to use or provide subsidized cessation aids. Healthcare providers should advise their patients about approaches to quitting. This study used the most recent nationally representative data for the United States to examine sociodemographic disparities in unaided quitting among current and former daily smokers who made a quit attempt in the last 12 months. Most quit attempts were unaided. People who were male, younger, non-Hispanic black, had lower nicotine dependence, and those who were low income were more likely to make an unaided quit attempt. These results could be used by policy makers and program planners to develop cessation interventions directed at specific populations to improve smoking cessation rates. © The Author 2016.

The aims of this paper are to compute the risks of dying of ischemic heart disease (IHD), lung cancer (LC), stroke, and chronic obstructive pulmonary disease (COPD) for Italian smokers by gender, age and daily number of cigarettes smoked, and to estimate the benefit of stopping smoking in terms of risk reduction. Life tables by sex and smoking status were computed for each smoking-related disease based on Italian smoking data, and risk charts with 10-year probabilities of death were computed for never, current and former smokers. Men aged 45-49 years, current smokers, have a 8, 10, 3 and 1 in 1,000 chance of dying of IHD, LC, stroke and COPD, respectively, whereas women with the same characteristics have a 2, 6, 3 and 1 in 1,000 chance, respectively, for all smokers combined, i.e., independent of the smoking intensity. The risk reduction rates from quitting smoking are remarkable: a man who quits smoking at 45-49 years can reduce the risk of dying of IHD, LC, stroke and COPD in the next 10 years by 43%, 53%, 57% and 55%, respectively; a woman by 49%, 49%, 59% and 57%, respectively. Estimates of risk reduction by quitting smoking are useful to provide a sounder scientific basis for public health messages and clinical advice.

To explore the emerging tobacco epidemic in female workers in the growing micro-electronics industry of Taiwan. Workers were surveyed regarding their smoking status, sociodemographics and work characteristics. In total, 1950 female employees in two large micro-electronics companies in Taiwan completed the survey. Approximately 9.3% of the female employees were occasional or daily smokers at the time of the survey. The prevalence of smoking was higher in those aged 16-19 years (20.9%), those not married (12.9%), those with a high school education or less (11.7%), those employed by Company A (11.7%), shift workers (14.3%), and those who had been in their present employment for 1 year or less (13.6%). Results of multivariate adjusted logistic regression indicated that younger age, lower level of education, shorter periods of employment with the company and shift working were the important factors in determining cigarette smoking among the study participants. The odds ratio of being a daily smoker was similar to that of being a current smoker. Marital status was the only significant variable when comparing former smokers with current smokers. Smoking prevalence in female workers in the two micro-electronics companies studied was much higher than previous reports have suggested about female smoking prevalence in Taiwan and China. We suggest that smoking is no longer a 'male problem' in Taiwan. Future smoking cessation and prevention programmes should target young working women as well as men.

Occupation could affect the distribution of smoking status of workers, and the success of smoking cessation among workers depends partly on worksite conditions. Blue collar workers have been identified as a high-risk group for smoking. The aim of the present study was to examine trends in smoking rates among urban civil servants in Japan according to occupational categories. Subjects were urban civil servants aged 30-59 years. They annually reported smoking status in a questionnaire in a worksite health check-up each year from 2004 to 2011. Urban civil servants reported substantially lower current smoking rates than national smoking rates in Japan (20.2%, 23.8%, and 27.0% for males in their 30s, 40s, and 50s and 2.4%, 6.3%, and 9.5% for females, respectively, in 2011). In analysis by occupational categories, current smoking rates declined among all groups except female white collar workers in their 50s. The current and persistent smoking rates (number of current smokers/[number of ex-smokers and current smokers]) among blue collar workers were higher than those among white collar workers at almost all time points in all age and gender groups. This study found relatively lower current smoking rates among urban civil servants than the national average and higher current and persistent smoking rates in blue collar workers than in white collar workers among them. These results would help to make suitable worksite smoking cessation policies for each occupational category.

To assess the prevalence and correlates of current smoking, awareness of hazards, and quitting behavior among smokers 30 years and above. Cross-sectional; Gokulpuri, a resettlement colony in East Delhi, India; 911, persons aged 30 years and above using systematic random sampling; Study tools: Semi-structured questionnaire. Prevalence of current smoking was found to be 24.6% (95% CI 21.90 - 27.49). Majority 198 (88.4%) of current smokers smoked bidi exclusively, and on an average 13.5 bidi/cigarette were smoked per day. Multivariate analysis showed the factors associated with current smoking as male sex, advancing age, illiteracy, skilled occupation, low socio-economic status, and low BMI (P < 0.001). 64.2% were aware of the hazards of smoking. 63 (21.9%) had quit smoking in the past, majority due to the health problems. Low educational status was associated with poor hazard awareness and quitting behavior. Smoking is a significant problem among poor and illiterate males, shows an increasing trend with an advancing age and is directly associated with skilled occupation and low BMI. There are significant gaps in knowledge regarding hazards of smoking.

The most effective action for primary prevention of chronic obstructive lung disease is smoking cessation early enough. In secondary prevention, smokers with airway obstruction were more likely to quit smoking. The aim of this study was to evaluate the impact of a public spirometry on smoking habits in terms of primary prevention. Spirometry with its medical analysis was offered to visitors of a local public event called 'Lange Nacht der Wissenschaften' ('Long night of sciences'). The impact of results on smoking habits was evaluated in all smokers with an anonymized questionnaire afterwards. Two hundred fifty-seven people with the median age of 30 years (interquartile range 22-46) were examined. Out of 44 current smokers (17.1%), only two individuals showed a prebronchodilator FEV1/forced vital capacity-value <0.7. Fourteen smokers stated to have an increased motivation to quit smoking whereas 28 smokers declared that their motivation to quit smoking was independent of spirometry result. These smokers were significantly younger (median age 28 vs. 40 years, P = 0.025) without differences in spirometry results or smoking habits. In an unselected population with a high amount of younger adults, normal spirometry did not show a short-term benefit for primary prevention of chronic obstructive lung disease in terms of increasing motivation to quit smoking. © 2013 John Wiley & Sons, Ltd.

Recent studies have described fungal sensitisation in patients with chronic obstructive pulmonary disease (COPD). However, no study has evaluated fungal sensitisation specifically in bidi smokers. Herein, we evaluate the prevalence of Aspergillus sensitisation in bidi smokers. Bidi smokers with and without COPD underwent chest radiography, spirometry, Aspergillus skin test, A. fumigatus precipitins, A. fumigatus-specific IgE and total IgE. Aspergillus sensitisation was defined as the presence of either immediate cutaneous hyperreactivity to Aspergillus antigen or raised A. fumigatus-specific IgE level >0.35 kUA/L. Bidis were obtained from a subset of cases and controls and cultured for the growth of any fungus. Two hundred subjects with COPD and 72 chronic bidi smokers without COPD were included in the study (258 men; mean age, 56.8 years). Aspergillus sensitisation was found to be significantly higher in bidi smokers without COPD (27.8%) compared to the COPD cases (16%). Age, COPD, lung function, severity of smoking and current smoking were not associated with Aspergillus sensitisation, on a multivariate logistic regression analysis. We found a high prevalence of Aspergillus sensitisation in bidi-smoking subjects. More studies are required to confirm the findings of our study. © 2017 Blackwell Verlag GmbH.

Nearly all adult smokers first try cigarettes before age 18 years (1), and adolescents can show symptoms of nicotine dependence within days to weeks of the onset of occasional cigarette smoking (2). Having a usual cigarette brand among adolescent smokers could reflect exposure and receptivity to pro-tobacco advertising and tobacco product appeal (1). To identify usual cigarette brands smoked among U.S. middle and high school students who were current (past 30-day) cigarette smokers, CDC analyzed data from the 2012-2016 National Youth Tobacco Survey (NYTS). Marlboro, Newport, and Camel were the most commonly reported brands smoked during 2012-2016; in 2016, these three were the brands usually smoked for 73.1% and 78.7% of current cigarette smokers in middle and high school, respectively. These three brands also were the three most commonly identified as having a "favorite cigarette ad" in 2012. Efforts to reduce youth exposure to pro-tobacco advertising could help reduce youth smoking (1,3).

The US Food and Drug Administration must consider whether to ban the use of menthol in cigarettes. This study examines how current smokers might respond to such a ban on menthol cigarettes. Convenience sample of adolescent and adult smokers recruited from an online survey panel. United States, 2010. A total of 471 adolescent and adult current cigarette smokers. Respondents were asked a series of questions about how they might react if menthol cigarettes were banned. In addition, participants completed a simulation purchase task to estimate the demand for menthol and non-menthol cigarettes across a range of prices. Overall, 36.1% of respondents said they always (18.9%) or usually (17.2%) smoked menthol cigarettes. When asked how they might respond to a ban on menthol cigarettes, 35% of current menthol smokers said they would stop smoking, and 25% said they would 'find a way to buy a menthol brand'. Those who reported they might quit tended to have greater current intentions to quit [odds ratio (OR) = 4.47], while those who reported that they might seek illicit menthol cigarettes were far less likely to report current intentions to quit (OR = 0.06). Estimates for demand elasticity for preferred cigarette type were similar for menthol (α = 0.0051) and non-menthol (α = 0.0049) smokers. Demand elasticity and peak consumption were related to usual cigarette type and cigarettes smoked per day, but did not appear to differ by race, gender or age. Preliminary evidence suggests that a significant minority of smokers of menthol cigarettes in the United States would try to stop smoking altogether if such cigarettes were banned. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

Cigarette smoking is a major risk factor for RA and has been associated with increased disease severity and lower rates of disease remission. We hypothesized that inflammation and disease activity would be associated with smoking status and this would be related to levels of ACPA. RA patients from the Veterans Affairs RA registry were studied (n = 1466): 76.9% anti-CCP2 positive, 89% male, median age 63 years (interquartile range 57-72), median disease duration 8.45 years (interquartile range 2.8-18). Baseline serum samples were evaluated for levels of anti-CCP2, RF, 19 distinct ACPAs and 17 cytokines. Smoking status at baseline was recorded as current, former or never. The association of smoking status with cytokines, autoantibodies and disease activity (DAS28) was evaluated. Among anti-CCP-positive RA patients, RA-associated cytokines (false-discovery rates q < 0.1%) and DAS28 (P < 0.01) were higher in current smokers compared with former or never smokers. DAS28 and cytokine levels were similar between former and never smokers. In contrast, ACPA concentrations were higher among both current and former smokers compared with never smokers, and levels of ACPA were not associated with DAS28 or cytokine levels. Among anti-CCP2-positive RA patients, current smoking status is associated with elevations in pro-inflammatory cytokines and increased RA disease activity. Similar levels of inflammation and disease activity among former and never smokers suggests that the detrimental effects of smoking could be ameliorated through tobacco cessation. The effect of tobacco cessation on RA disease activity should be evaluated prospectively. Published by Oxford University Press on behalf of the British Society for Rheumatology 2016.

Background Despite universal acceptance that smoking is harmful, a substantial number of adults continue to smoke. The development of potential reduced exposure products (more recently termed modified risk tobacco products) has been suggested as a way to reduce the risks of tobacco smoking. This trial is designed to investigate whether changes in toxicant exposure after switching from a commercial to reduced toxicant prototype (RTP) cigarette (7 mg International Organisation for Standardisation (ISO) tar yield) can be assessed by measurement of biomarkers and other factors. The primary objective is to descriptively assess changes in selected biomarkers of exposure (BoE) and biomarkers of biological effect (BoBE) within participants and within and between groups after switching. Secondary objectives are to assess similarly changes in other biomarkers, quality of life, smoking behaviours, physiological measures, mouth-level exposure to toxicants and sensory perception. Methods/design This trial will assess current smokers, ex-smokers and never-smokers in a single-centre single-blind, controlled clinical trial with a forced-switching design and in-clinic (residential) and ambulatory (non-residential) periods. Smokers will be aged 23–55 years (minimum legal smoking age plus 5 years) and non-smokers 28–55 years (minimum legal smoking age plus 5 years, plus minimum 5 years since last smoked). Smokers will be allowed to smoke freely at all times. We will assess changes in selected BoE and BoBE and effective dose in urine and blood after switching. Creatinine concentrations in serum, creatinine clearance in urine, cotinine concentration in saliva, diaries and collection of spent cigarette filters will be used to assess compliance with the study protocol. Mouth-level exposure to toxins will be assessed by filter analysis. Discussion Data from this study are expected to improve scientific understanding of the effects of RTP cigarettes on BoE and BoBE, and give insights into study design for clinical assessment of potential MRTPs. Trial registration The study was registered in the Current Controlled Trials database under the reference ISRCTN81286286. PMID:23895296

This study assessed the utility of the pooled cohort equation (PCE) and/or coronary artery calcium (CAC) for atherosclerotic cardiovascular disease (ASCVD) risk assessment in smokers, especially those who were lung cancer screening eligible (LCSE). The U.S. Preventive Services Task Force recommended and the Centers for Medicare & Medicaid Services currently pays for annual screening for lung cancer with low-dose computed tomography scans in a specified group of cigarette smokers. CAC can be obtained from these low-dose scans. The incremental utility of CAC for ASCVD risk stratification remains unclear in this high-risk group. Of 6,814 MESA (Multi-Ethnic Study of Atherosclerosis) participants, 3,356 (49.2% of total cohort) were smokers (2,476 former and 880 current), and 14.3% were LCSE. Kaplan-Meier, Cox proportional hazards, area under the curve, and net reclassification improvement (NRI) analyses were used to assess the association between PCE and/or CAC and incident ASCVD. Incident ASCVD was defined as coronary death, nonfatal myocardial infarction, or fatal or nonfatal stroke. Smokers had a mean age of 62.1 years, 43.5% were female, and all had a mean of 23.0 pack-years of smoking. The LCSE sample had a mean age of 65.3 years, 39.1% were female, and all had a mean of 56.7 pack-years of smoking. After a mean of 11.1 years of follow-up 13.4% of all smokers and 20.8% of LCSE smokers had ASCVD events; 6.7% of all smokers and 14.2% of LCSE smokers with CAC = 0 had an ASCVD event during the follow-up. One SD increase in the PCE 10-year risk was associated with a 68% increase risk for ASCVD events in all smokers (hazard ratio: 1.68; 95% confidence interval: 1.57 to 1.80) and a 22% increase in risk for ASCVD events in the LCSE smokers (hazard ratio: 1.22; 95% confidence interval: 1.00 to 1.47). CAC was associated with increased ASCVD risk in all smokers and in LCSE smokers in all the Cox models. The C-statistic of the PCE for ASCVD was higher in all smokers compared with LCSE smokers (0.693 vs. 0.545). CAC significantly improved the C-statistics of the PCE in all smokers but not in LCSE smokers. The event and nonevent net reclassification improvements for all smokers and LCSE smokers were 0.018 and -0.126 versus 0.16 and -0.196, respectively. In this well-characterized, multiethnic U.S. cohort, CAC was predictive of ASCVD in all smokers and in LCSE smokers but modestly improved discrimination over and beyond the PCE. However, 6.7% of all smokers and 14.2% of LCSE smokers with CAC = 0 had an ASCVD event during follow-up. Copyright © 2018 American College of Cardiology Foundation. Published by Elsevier Inc.

Classifying a Smoker Scale in Adult Daily and Nondaily Smokers
2014-01-01
Introduction: Smoker identity, or the strength of beliefs about oneself as a smoker, is a robust marker of smoking behavior. However, many nondaily smokers do not identify as smokers, underestimating their risk for tobacco-related disease and resulting in missed intervention opportunities. Assessing underlying beliefs about characteristics used to classify smokers may help explain the discrepancy between smoking behavior and smoker identity. This study examines the factor structure, reliability, and validity of the Classifying a Smoker scale among a racially diverse sample of adult smokers. Methods: A cross-sectional survey was administered through an online panel survey service to 2,376 current smokers who were at least 25 years of age. The sample was stratified to obtain equal numbers of 3 racial/ethnic groups (African American, Latino, and White) across smoking level (nondaily and daily smoking). Results: The Classifying a Smoker scale displayed a single factor structure and excellent internal consistency (α = .91). Classifying a Smoker scores significantly increased at each level of smoking, F(3,2375) = 23.68, p < .0001. Those with higher scores had a stronger smoker identity, stronger dependence on cigarettes, greater health risk perceptions, more smoking friends, and were more likely to carry cigarettes. Classifying a Smoker scores explained unique variance in smoking variables above and beyond that explained by smoker identity. Conclusions: The present study supports the use of the Classifying a Smoker scale among diverse, experienced smokers. Stronger endorsement of characteristics used to classify a smoker (i.e., stricter criteria) was positively associated with heavier smoking and related characteristics. Prospective studies are needed to inform prevention and treatment efforts. PMID:24297807
Are smokers adequately informed about the health risks of smoking and medicinal nicotine?

The present study assessed smokers' beliefs about the health risks of smoking and the benefits of smoking filtered and low-tar cigarettes, and their awareness of and interest in trying so-called reduced-risk tobacco products. Results were based on a nationally representative random-digit-dialed telephone survey of 1,046 adult (aged 18 years or older) current cigarette smokers. Data were gathered on demographic characteristics, tobacco use behaviors, awareness and use of nicotine medications, beliefs about the health risks of smoking, content of smoke and design features of cigarettes, and the safety and efficacy of nicotine medications. In addition, respondents were asked about their interest in and perceived ability to stop smoking and about their desire for more information about the health risks of smoking. Smokers were least knowledgeable about low-tar and filter cigarettes (65% of responses were incorrect or "don't know") and most knowledgeable about the health risks of smoking (39% of responses were incorrect or "don't know"). The smokers' characteristics most commonly associated with misinformation when all six indices were combined into a summary index were as follows: those aged 45 years or older, smokers of ultralight cigarettes, smokers who believe they will stop smoking before they experience a serious health problem caused by smoking, smokers who have never used a stop-smoking medication, and smokers with a lower education level. Those who believed they would stop smoking in the next year were more knowledgeable about smoking. Some 77% of respondents reported a desire for additional information from tobacco companies on the health dangers of smoking. The present findings demonstrate that smokers are misinformed about many aspects of the cigarettes they smoke and stop-smoking medications and that they want more information about ways to reduce their health risks.
Youth tobacco surveillance--United States, 1998-1999.
2000-10-13
Tobacco use is the single leading preventable cause of death in the United States, accounting for approximately, 430,000 deaths each year. The prevalence of cigarette smoking nationwide among high school students increased during the 1990s, peaking in 1996-1997, then began a gradual decline. Approximately 80% of tobacco users initiate use before the age of 18 years. If the trend in early initiation of cigarette smoking continues, approximately 5 million children aged <18 years who are living today will die prematurely as adults because they began to smoke cigarettes during adolescence. The economic liability associated with tobacco use ranges from $50 billion to $73 billion per year in medical expenses alone. Because of these health and economic consequences, CDC has recommended that states establish and maintain comprehensive tobacco control programs to reduce tobacco use among youth. February 1998 through December 1999. To assist states in developing and maintaining their state-based comprehensive tobacco prevention and control programs, CDC developed the Youth Tobacco Surveillance and Evaluation System, which includes international, national, and state school-based surveys of middle school and high school students. Two components of this system are discussed--the National Youth Tobacco Survey and the state Youth Tobacco Surveys. The national survey is representative of students in the 50 states and the District of Columbia; 15,061 students in 131 schools completed questionnaires in 1999. The state surveys were first conducted in 1998, when three states participated, and in 1999, when 13 states participated (13 states conducted middle school surveys and 10 states conducted high school surveys); state sample sizes ranged from 452 to 15,478 students. This report summarizes data from the 1999 national survey and the 1998 and 1999 state surveys. Findings from the National Youth Tobacco Survey show current tobacco use ranges from 12.8% among middle school students to 34.8% among high school students. Cigarette smoking is the most prevalent form of tobacco used, followed by cigars and smokeless tobacco. Young people have strong cigarette brand preferences. Almost half of current smokers in both middle school and high school report that they usually smoke Marlboro cigarettes. Black students are more likely to smoke Newport cigarettes than any other brand. Half of current smokers in middle school and high school report that they want to completely stop smoking. Nearly one fourth of middle school and high school students who have never smoked cigarettes indicate that they are susceptible to initiating smoking in the next year. Environmental tobacco smoke exposure is very high among both middle school and high school students. During the week before the survey, approximately 9 out of 10 current smokers and half of never smokers were in the same room with someone who was smoking; 8 out of 10 current smokers and 3 out of 10 never smokers rode in a car with someone who was smoking. Six out of 10 current smokers and 3 out of 10 never smokers live in a home where someone else smokes cigarettes. Approximately 70% of middle school and 60% of high school students who currently smoke and are aged <18 years were not asked to show proof of age when they purchased cigarettes. Approximately three fourths of middle school and high school students have seen antismoking commercials; however, 90% report having seen actors smoking on television or in the movies. Approximately 2% of middle school and high school students who had never used tobacco would wear or use something with a tobacco company name or picture on it. This rate increases to approximately 20% for current tobacco users. Youth Tobacco Survey data are used by health and education officials to improve national and state programs to prevent and control youth tobacco use. (ABSTRACT TRUN

OBJECTIVE: The aim of this study was to analyze social characteristics and stress as correlates of cigarette smoking in adolescence. The main intent was to identify elements that distinguish adolescents who had experimented with smoking and did not progress to regular smoking from those who became current smokers. METHODS: Students at 10 high schools in the city of Ribeirão Preto, Brazil, completed a questionnaire based on an instrument employed in a similar large-scale study. The students were classified as never-smokers or experimenters. The experimenters were subcategorized as having become current smokers or nonprogressors. Analyses were performed using adjusted logistic models. RESULTS: A total of 2,014 students (mean age, 16.2 ± 1.1 years; females, 53%) completed the questionnaire. We categorized 1,283 students (63.7%) as never-smokers, 244 (12.1%) as current smokers, and 487 (24.2%) as nonprogressors. We found that experimentation with smoking was associated with being held back a grade in school (OR = 1.80), alcohol intake (low/occasional, OR = 8.92; high/regular, OR = 2.64), illicit drug use (OR = 9.32), having a sibling or cousin who smokes (OR = 1.39), having a friend who smokes (OR = 2.08), and high levels of stress (in females only, OR = 1.32). Factors associated with an increased risk of transitioning from experimenter to current smoker were alcohol intake (low/occasional, OR = 3.28; high/regular, OR = 2.16), illicit drug use (OR = 3.61), and having a friend who smokes (OR = 7.20). CONCLUSIONS: Current smoking was associated with a profile of socioeconomic correlates different from that associated with experimentation only. Our data (showing that current smoking was associated with having a friend who smokes, alcohol intake, and illicit drug use) suggest the need for comprehensive approaches to discourage substance use during adolescence.

Secondhand smoke (SHS) likely provides additional exposure to nicotine and toxins for smokers, but has been understudied. Our objective was to determine whether SHS exposure among smokers yields detectable differences in cotinine levels compared with unexposed smokers at the population level. Using the US National Health and Nutrition Examination Survey (NHANES) for the years 1999-2012, we compared serum cotinine levels of 4547 current adult cigarette smokers stratified by self-reported SHS exposure sources (home and/or work) and smoking intensity. A weighted multivariable linear regression model determined the association between SHS exposure and cotinine levels among smokers. Smokers with SHS exposure at home (43.8%) had higher cotinine levels (β=0.483, p≤0.001) compared with those with no SHS exposure at home after controlling for the number of cigarettes smoked per day and number of days smoked in the previous 5 days, survey year, age, gender and education. Smokers with SHS exposure at work (20.0%) did not have significantly higher cotinine levels after adjustment. The adjusted geometric mean cotinine levels of light smokers (1-9 cigarettes per day) with no SHS exposure, exposure at work only, home only, and both home and work were 52.0, 62.7, 67.2, 74.4 ng/mL, respectively, compared with 219.4, 220.9, 255.2, 250.5 ng/mL among moderate/heavy smokers (≥10 cigarettes per day). Smokers living in residences where others smoke inside the home had significantly higher cotinine levels than smokers reporting no SHS exposure, regardless of individual smoking intensity. Future research should target the role that SHS exposure may have in nicotine dependence, cessation outcomes and other health impacts among smokers. Published by the BMJ Publishing Group Limited.

Objectives. We examined the extent to which adolescents in Norway have been exposed to tobacco marketing despite an existing ban, and whether exposure is related to their current smoking or expectations they will smoke in the future. Methods. Questionnaires were administered to nationally representative systematic samples of Norwegian youths aged 13 to 15 years in 1990 (n = 4282) and 1995 (n = 4065). Results. About half in each cohort reported exposure to marketing. Youths reporting exposure were significantly more likely to be current smokers and to expect to be smokers at 20 years of age, after control for important social influence predictors. Conclusions. Adolescents’ current smoking and future smoking expectations are linked to marketing exposure even in limited settings, suggesting the need for comprehensive controls to eliminate the function of marketing in promoting adolescent smoking.

Reformed smokers have survival benefits after head and neck cancer.

Smoking tobacco is the main risk factor for head and neck cancer, is proportional to the number of pack years (number of packs smoked/day x number of years of smoking), and is reduced when the patient stops smoking. Current molecular evidence has suggested that tobacco-related cancers could be clinically more aggressive than cancers in non-smokers, particularly in the head and neck. However, clinical studies have not uniformly reproduced the relation between survival and tobacco, possibly because they ignore the health benefit that reformed smokers obtain during the period between giving up smoking and the diagnosis of cancer, which is not shared by those who continue to smoke and develop cancer. We have investigated the survival of reformed smokers, non-smokers, and continuing smokers after a diagnosis of head and neck cancer. The data of patients with head and neck cancer from 1992 -2013 from the Cancer Genome Atlas database were analysed using a multivariate Cox's regression model for survival, and Kaplan-Meier curves were produced for smoking history. A total of 521 patients were treated for head and neck cancer, and there was a significant difference in survival between reformed and non-smokers on the one hand, and current smokers on the other (p=0.02). The significance increased when reformed smokers were grouped according to their duration of abstinence and time of diagnosis of cancer (>15 and ≤15 years, p<0.01). Smoking history was a significant prognostic factor in the multivariate Cox's regression model when analysed with age, stage, grade, and site. We conclude that reformed smokers have a survival benefit in head and neck cancer. Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

OBJECTIVES—To: evaluate the impact of smoking status on objective productivity and absenteeism measures; evaluate the impact of smoking status on subjective measures of productivity; and assess the correlation between subjective and objective productivity measures. DESIGN—Prospective cohort study in a workplace environment. SUBJECTS—Approximately 300 employees (100 each of former, current, and never smokers) at a reservation office of a large US airline. MAIN OUTCOME MEASURES—Objective productivity and absenteeism data were supplied by the employer. Subjective assessments of productivity were collected using a self report instrument, the Health and Work Questionnaire (HWQ). RESULTS—Current smokers had significantly greater absenteeism than did never smokers, with former smokers having intermediate values; among former smokers, absenteeism showed a significant decline with years following cessation. Former smokers showed an increase in seven of 10 objective productivity measures as compared to current smokers, with a mean increase of 4.5%. While objective productivity measures for former smokers decreased compared to measures for current smokers during the first year following cessation, values for former smokers were greater than those for current smokers by 1-4 years following cessation. Subjective assessments of "productivity evaluation by others" and "personal life satisfaction" showed significant trends with highest values for never smokers, lowest for current smokers, and intermediate for former smokers. CONCLUSIONS—Workplace productivity is increased and absenteeism is decreased among former smokers as compared to current smokers. Productivity among former smokers increases over time toward values seen among never smokers. Subjective measures of productivity provide indications of novel ways of productivity assessment that are sensitive to smoking status.

To estimate the cost-effectiveness of noncardia gastric adenocarcinoma (NCGA) screening strategies based on new biomarker and endoscopic technologies. Using an intestinal-type NCGA microsimulation model, we evaluated the following one-time screening strategies for US men: (1) serum pepsinogen to detect gastric atrophy (with endoscopic follow-up of positive screen results), (2) endoscopic screening to detect dysplasia and asymptomatic cancer (with endoscopic mucosal resection (EMR) treatment for detected lesions) and (3) Helicobacter pylori screening and treatment. Screening performance, treatment effectiveness, cancer and cost data were based on published literature and databases. Subgroups included current, former and never smokers. Outcomes included lifetime cancer risk and incremental cost-effectiveness ratios (ICERs), expressed as cost per quality-adjusted-life-year (QALY) gained. Screening the general population at age 50 years reduced the lifetime intestinal-type NCGA risk (0.24%) by 26.4% with serum pepsinogen screening, 21.2% with endoscopy and EMR and 0.2% with H. pylori screening/treatment. Targeting current smokers reduced the lifetime risk (0.35%) by 30.8%, 25.5%, and 0.1%, respectively. For all subgroups, serum pepsinogen screening was more effective and more cost-effective than all other strategies, although its ICER varied from $76,000/QALY (current smokers) to $105,400/QALY (general population). Results were sensitive to H. pylori prevalence, screen age and serum pepsinogen test sensitivity. Probabilistic sensitivity analysis found that at a $100,000/QALY willingness-to-pay threshold, the probability that serum pepsinogen screening was preferred was 0.97 for current smokers. Although not warranted for the general population, targeting high-risk smokers for serum pepsinogen screening may be a cost-effective strategy to reduce intestinal-type NCGA mortality.

Sri Lanka became a signatory to the WHO Frame Work Convention on Tobacco Control in September 2003, and this was ratified in November 2003. With a view to reduce the use of tobacco in Sri Lanka, the National Authority on Tobacco and Alcohol Act (NATA) No. 27 of 2006 was implemented. To assess the behavior changes related to tobacco use among adolescents and young adults following exposure to tobacco control measures were implemented by NATA. A case-control study was conducted on 42 adolescent (aged 13-19 years) and 156 young adult (aged 20-39 years) men living in Anuradhapura Divisional Secretary area in Sri Lanka. Cases (current quitters) and controls (current smokers) were compared to ascertain the outcome following the exposure to tobacco control measures. A self-administered questionnaire and focus group discussions were used to ascertain the exposure status in cases and controls. Confounding was controlled by stratification and randomization. Univariate analysis was performed by Backward Stepwise (Likelihood Ratio) method. Among 198 respondents, 66 (27.3% adolescents and 72.7% young adults) were quitters, while 132 smokers (18.2% adolescents and 81.8% young adults) were current smokers. Exposure to the anti-smoking media messages revealed that TV was the strongest media that motivated smokers to quit smoking. Majority (66%) of cases and control were not exposed to tobacco promotion advertisements, while 47% of the cases and 50% of the control had never seen tobacco advertisements during community events. All cases (66) as well as 89% (118) of the control had not noticed competitions or prizes sponsored by tobacco industry during last year ( P = 0.13). Tobacco control measures implemented by NATA had a favorable influence on behavior change related to smoking among quitters and current smokers.
Sectors of the Russian economy that would benefit from reduced cigarette sales.

Cigarette companies argue that tobacco control measures will harm the Russian economy. Research in other countries has refuted this claim. To identify how current and former smokers would (or did) spend their cigarette money if (or when) they quit smoking. A nationwide face-to-face survey of 1599 participants aged 18 years and older in 128 cities was conducted in Russia during May 2008 by the Russian Levada Analytical Center. In all, 10% of respondents were former smokers and 33% were current smokers. Respondents indicated that they would spend their cigarette money on selected items if they quit. These items, from most to least common are groceries, recreation, housing, clothing, transportation, healthcare and savings. The ways that cigarette money would be spent in the absence of smoking significantly differed according to smoking status, gender, age, education, income, rural versus urban residency and geographic region. Tobacco control may benefit the Russian economy by producing healthier workers and because the money that would have been used for cigarettes would be shifted primarily to groceries, recreation, housing and clothing.
Flexible emotion-based decision-making behavior varies in current and former smokers.

Suboptimal decision-making is a feature in the initiation and maintenance of substance use, often manifested in choosing for short-term benefits rather than long-term gain, and the failure to display cognitive flexibility, respectively. Studies of nicotine users typically focus on characterizing those who are already addicted; less is known about decision-making in former smokers. Non- (n=21), former daily- (n=23) and current daily smokers (n=24), completed the contingency-shifting variant Iowa Gambling Task (csIGT), in which the reward and punishment contingencies of the decks are systematically varied after 100 trials of the 'standard' IGT. Scores on the standard blocks of the csIGT provided an index of emotion-based decision-making, while the contingency-shifting blocks assessed flexible decision-making. Subjective ratings were also recorded at 20-trial intervals. Both current and former smokers showed significantly impaired performance relative to non-smokers when making decisions during the standard blocks of the csIGT. Both former and non-smokers' awareness of the reward/punishment contingencies was significantly higher than those of current smokers at the end of the standard IGT. Both former and non-smokers had significantly better performance on the contingency shifting blocks, relative to current smokers. The findings indicate that both current and former smokers display a suboptimal pattern of decision-making than non-smokers during the standard IGT. However, with respect to the ability to change behavior following reversed contingencies, former smokers are more similar to non-smokers than to current smokers. Former smokers were also more aware of the contingencies than current smokers. Copyright © 2015 Elsevier Ltd. All rights reserved.

Cigarette smoking is a risk factor for ageing-related disease, but its association with biological ageing, indicated by telomere length, is unclear. We systematically reviewed evidence evaluating association between smoking status and telomere length. Searches were performed in MEDLINE (Ovid) and EMBASE (Ovid) databases, combining variation of keywords "smoking" and "telomere". Data was extracted for study characteristics and estimates for association between smoking and telomere length. Quality of studies was assessed with a risk of bias score, and publication bias was assessed with a funnel plot. I 2 test was used to observe heterogeneity. Meta-analysis was carried out to compare mean difference in telomere length by smoking status, and a dose-response approach was carried out for pack-years of smoking and telomere length. A sensitivity analysis was carried out to examine sources of heterogeneity. A total of 84 studies were included in the review, and 30 among them were included in our meta-analysis. Potential bias was addressed in half of included studies, and there was little evidence of small study bias. Telomere length was shorter among ever smokers compared to never smokers (summary standard mean difference [SMD]: -0.11 (95% CI -0.16 to -0.07)). Similarly, shorter telomere length was found among smokers compared to non-smokers, and among current smokers compared to never or former smokers. Dose-response meta-analysis suggested an inverse trend between pack-years of smoking and telomere length. However, heterogeneity among some analyses was observed. Shorter telomeres among ever smokers compared to those who never smoked may imply mechanisms linking tobacco smoke exposure to ageing-related disease. Copyright © 2017 The Authors.

To examine screening adenoma detection rates (ADR) and serrated detection rates (SDR) among smokers and obese adults in the New Hampshire Colonoscopy Registry. ADR, a quality measure for screening colonoscopies, is associated with protection from interval colorectal cancer. Currently, only sex-specific ADR benchmarks are reported. However, obesity and smoking ≥20 pack-years are strong predictors for colorectal neoplasia, as highlighted by the 2009 American College of Gastroenterology CRC Screening Guidelines. Data comparing ADR in smokers and obese adults to those without these risks are limited. We calculated ADR, SDR, and 95% confidence intervals for screening colonoscopies in participants ≥50 years. Sex-specific and sex-age-specific rates were compared by smoking exposure (never vs. <20 vs. ≥20 pack-years) and body mass index (<30 vs. ≥30). A total of 21,539 screening colonoscopies were performed by 77 endoscopists at 20 facilities (April 2009 to September 2013). The difference in ADR between nonsmokers and smokers with ≥20 pack-years was 8.8% (P<0.0001) and between obesity groups 5.0% (P<0.0001). Significant sex-specific and sex-age-specific increases in ADR and SDR were found among smokers and obese participants. ADR and SDR for smokers and obese adults were significantly higher than their counterparts without those risks. Endoscopists should consider the prevalence of these risks within their screening population when comparing their rates to established benchmarks. Calculating sex-specific or sex-age-specific ADR and SDR based on smoking and obesity may provide optimal protection for populations with a particularly high prevalence of smokers and obese adults.
Smoke and Mirrors: The Perceived Benefits of Continued Tobacco use Among Current Smokers
Klein, Hugh; Sterk, Claire E.; Elifson, Kirk W.

Despite 50+ years of public health efforts to reduce smoking rates in the United States, approximately one-fifth of the adults living in this country continue to smoke cigarettes. Previous studies have examined smokers’ risk perceptions of cigarette smoking, as well as the perceived benefits of quitting smoking. Less research has focused on the perceived benefits of smoking among current cigarette smokers. The latter is the main focus of the present paper. Questionnaire-based interviews were conducted with a community-based sample of 485 adult current cigarette smokers recruited from the Atlanta, Georgia, metropolitan area between 2004 and 2007. Active and passive recruiting approaches were used, along with a targeted sampling strategy. Results revealed that most current cigarette smokers perceive themselves to experience benefits as a result of their cigarette use, including (among others) increased relaxation, diminished nervousness in social situations, enjoyment of the taste of cigarettes when smoking, and greater enjoyment of parties when smoking. Perceiving benefits from cigarette smoking was associated with a variety of tobacco use measures, such as smoking more cigarettes, an increased likelihood of chain smoking, and overall negative attitude toward quitting smoking, among others. Several factors were associated with the extent to which smokers perceived themselves to benefit from their tobacco use, including education attainment, the age of first purchasing cigarettes, the proportion of friends who smoked, hiding smoking from others, being internally-oriented regarding locus of control, and self-esteem.

Presenting to primary care with potential cancer symptoms is contingent on one's ability to recognize potentially serious symptoms. We investigated differences between smokers and non-smokers in symptoms experienced, awareness and consulting of potential respiratory, head and neck cancer symptoms. Smokers and non-smokers aged over 50 from Yorkshire general practice lists were sent a postal questionnaire asking about symptoms, consulting and awareness of cancer symptoms. Data were analysed using STATA14. Response rate after one reminder was 30.5% (1205/3954). Smoking status was associated with experience of cough (p<0.001), breathlessness (p = 0.002) and tiredness (p = 0.004) with smokers (25.8% of population) more likely than never-smokers (53.6% of population) to experience all three symptoms (cough OR = 2.56;95%CI[1.75-3.75], breathlessness OR = 2.39;95%CI[1.43-4.00], tiredness OR = 1.57;95%CI[1.12-2.19]). Smoking status was associated with awareness of breathlessness as a potential cancer symptom (p = 0.035) and consulting for cough (p = 0.011) with smokers less likely to consult than never-smokers (OR = 0.37;95% CI[0.17-0.80]). Our findings suggest that current smokers are more likely to experience cough, breathlessness and tiredness, but are less likely to consult for cough than never-smokers. To increase cancer awareness and promote consulting among smokers, innovative interventions improving symptom recognition and empowering smokers to seek help are required.
Are adolescents attempting to buy cigarettes on the internet?

OBJECTIVE— To assess the prevalence of, and demographic and smoking behaviour correlates of, attempting to purchase cigarettes via the internet among adolescent current smokers. METHODS— A representative sample of 17 181 10th and 12th grade California students completed a written questionnaire on tobacco related attitudes and behaviour during the 1999-2000 school year. Logistic regression analyses were used to determine the variables associated with attempting to purchase cigarettes on the internet. RESULTS—Among youth under 18 years of age who were current smokers (n = 1689), 2.2% (95% confidence interval 1.5% to 2.9%) reported attempting to purchase cigarettes on the internet. Attempted internet purchases were more likely among younger respondents, males, frequent smokers, and respondents reporting lower perceived availability of tobacco products from retail and social sources. CONCLUSIONS—Few adolescent smokers in California surveyed during the 1999-2000 school year had attempted to obtain cigarettes from the internet. As internet access increases, future studies should examine whether internet cigarette vendors sell to minors and whether adolescents are purchasing cigarettes on the internet. Keywords: internet cigarette vendors; adolescent smokers; purchasing PMID:11740028
[Effects of spirometric screening in the community on smoking cessation].

In the years 1998-2000 in the Centre of COPD and Respiratory Failure in Bydgoszcz a group of tobacco smokers at risk of COPD (over 40 years of age, with smoking history of more than 10 packyears) were studied. Every patient filled-in a simple questionnaire on clinical signs of COPD and tobacco habit, had a spirometry performed according to ATS standards and received a short antitobacco counseling together with a booklet on how to quit smoking. Out of 1072 patients studied in 1998, airway obstruction was found in 200. Eighty seven of these were current smokers (studied group-S). Another 90 current smokers with normal spirometry served as a control group-C. Both groups of smokers were invited in 1999 and 2000 to perform spirometry. Changes in smoking habit were recorded at each yearly visit. After one year 13 patients (15%) from the S group and 4 (4.5%) from the C group permanently stopped smoking. In 2000 24 patients (28%) in S group and 13 (14.7%) in C group permanently quit smoking. Spirometric screening in smokers at risk of COPD together with a minimal antismoking intervention seems to be a promising method of smoking cessation.

We investigated regional air trapping on computed tomography in current smokers with normal spirometry. It was hypothesised that presence of regional air trapping may indicate a specific manifestation of smoking-related changes.40 current smokers, 40 patients with chronic obstructive pulmonary disease (COPD), and 40 healthy never- smokers underwent computed tomography scans. Regional air trapping was assessed on end-expiratory scans and emphysema, micronodules and bronchial wall thickening on inspiratory scans. The ratio of expiratory and inspiratory mean lung attenuation (E/I) was calculated as a measure of static (fixed) air trapping.Regional air trapping was present in 63% of current smokers, in 45% of never smokers and in 8% of COPD patients (p<0.001). Current smokers with and without regional air trapping had E/I ratio of 0.81 and 0.91, respectively (p<0.001). Forced expiratory volume in 1 s (FEV 1 ) was significantly higher and emphysema less frequent in current smokers with regional air trapping.Current smokers with regional air trapping had higher FEV 1 and less emphysema on computed tomography. In contrast, current smokers without regional air trapping resembled COPD. Our results highlight heterogeneity among smokers with normal spirometry and may contribute to early detection of smoking related structural changes in the lungs. Copyright ©ERS 2017.

We illustrate the effect of survival bias when investigating risk factors for eye disease in elderly populations for whom death is a competing risk. Our investigation focuses on the relationship between smoking and late age-related macular degeneration (AMD) in an observational study impacted by censoring due to death. Statistical methodology to calculate the survivor average causal effect (SACE) as a sensitivity analysis is described, including example statistical computing code for Stata and R. To demonstrate this method, we examine the causal effect of smoking history at baseline (1990-1994) on the presence of late AMD at the third study wave (2003-2007) using data from the Melbourne Collaborative Cohort Study. Of the 40,506 participants eligible for inclusion, 38,092 (94%) survived until the start of the third study wave, 20,752 (51%) were graded for AMD (60% female, aged 47-85 years, mean 65 ± 8.7 years). Late AMD was detected in 122 participants. Logistic regression showed strong evidence of an increased risk of late AMD for current smokers compared to non-smokers (adjusted naïve odds ratio 2.99, 95% confidence interval, CI, 1.74-5.13). Among participants expected to be alive at the start of follow-up regardless of their smoking status, the estimated SACE odds ratio comparing current smokers to non-smokers was at least 3.42 (95% CI 1.57-5.15). Survival bias can attenuate associations between harmful exposures and diseases of aging. Estimation of the SACE using a sensitivity analysis approach should be considered when conducting epidemiological research within elderly populations.

Abdominal aortic aneurysm (AAA) is an important vascular disease in older adults, but data on lifetime risk of AAA are sparse. We examined lifetime risk of AAA in a community-based cohort and prospectively assessed the association between midlife cardiovascular risk factors and AAAs. In ARIC study (Atherosclerosis Risk in Communities), 15 792 participants were recruited at visit 1 in 1987 to 1989 and followed up through 2013. Longitudinal smoking status was defined using smoking behavior ascertained from visit 1 (1987-1989) to visit 4 (1996-1998). We followed up participants for incident, clinical AAAs using hospital discharge diagnoses, Medicare outpatient diagnoses, or death certificates through 2011 and identified 590 incident AAAs. An abdominal ultrasound was conducted in 2011 to 2013 in 5911 surviving participants, and 75 asymptomatic AAAs were identified. We estimated the lifetime risk of AAA from the index age 45 years through 85 years of age. At age 45, the lifetime risk for AAA was 5.6% (95% confidence interval, 4.8-6.1) and was higher in men (8.2%) and current smokers (10.5%). Smokers who quit smoking between visit 1 and visit 4 had a 29% lower AAA lifetime risk compared with continuous smokers but had a higher risk than pre-visit 1 quitters. The lifetime risk of rupture or medical intervention was 1.6% (95% confidence interval, 1.2-1.8). Smoking, white race, male sex, greater height, and greater low-density lipoprotein or total cholesterol were associated with an increased risk of clinical AAA and asymptomatic AAA. At least 1 in 9 middle-aged current smokers developed AAA in their lifetime. Smoking cessation reduced the lifetime risk of AAA. © 2016 American Heart Association, Inc.

Only a few studies have provided information on awareness, use, and harm perceptions of e-cigarettes in Europe. We fill the knowledge gap in Italy. We used data from a face-to-face survey conducted in 2013 of a sample of 3,000 individuals, representative of the Italian population aged ≥15 years (51.1 million inhabitants). Awareness of e-cigarettes was 91.1%; it was lowest among women (87.8%), the elderly (78.4%), those with less education (84.1%), and never-smokers (89.0%). Ever e-cigarette use was 6.8% overall and was inversely related to age, whereas no significant difference was observed according to sex. With regard to smoking status, 2.6% of never-smokers, 7.0% of ex-smokers, and 20.4% of current smokers tried the e-cigarette at least once. Regular e-cigarette use was 1.2% overall, 1.5% among men, and 0.9% among women, and it was highest among young (2.4%) and current smokers (3.7%). Among 36 e-cigarette regular users, 22.0% did not change their smoking habit, 67.7% reduced traditional cigarette consumption, and 10.4% quit smoking. After fewer than 3 years from the opening of the first Italian e-cigarette shop, more than 45 million Italians have heard about e-cigarettes, 3.5 million have tried e-cigaretts, and more than 600,000 Italians regularly use e-cigarettes. Three out of 4 e-cigarette users reported to have favorably modified their smoking habit; however, 90% of users did not quit smoking as a consequence of starting vaping e-cigarettes. Almost 900,000 Italian never-smokers, particularly young never-smokers, have tried this new and potentially addictive product at least once. © The Author 2014.

To assess whether exposure to movie smoking is associated with cigarette smoking among Argentinian adolescents. A school-based longitudinal study involving 33 secondary schools in Argentina was performed. The sample included 2502 never smokers (average age at entry = 12.5 years), 1700 (67.9%) of whom completed follow-up surveys 17 months later. Exposure to the top 100 highest-grossing films for each year between 2009 and 2013 was assessed by content-coding films for tobacco and then by asking adolescents whether they had seen each of 50 titles, randomly selected from the larger pool, then parsing exposure into tertiles. Logistic regression models estimated aOR for the following transitions: nonsusceptible to susceptible never smoker, never smoker to ever smoker, and never smoker to current smoking (last 30 days). At follow-up, 34.4% of nonsusceptible never smokers became susceptible, 24.1% reported having tried smoking, and 9.4% were current smokers. Most exposure to movie smoking was from US-produced films (average 60.3 minutes compared with only 3.4 minutes from Argentine films). Greater exposure to smoking in movies was significantly associated with increased odds of becoming susceptible (aOR first vs third tertile 1.77, 95% CI 1.30-2.41), of trying smoking (aOR first vs third tertile 1.54, 1.14-2.08), and marginally associated with current smoking (AOR first vs third tertile 1.54, 0.99-2.40). Exposure to smoking in US- or Argentine-produced films had similar associations. In Argentina, exposure to smoking in the movies predicted future smoking transitions among early adolescents, with most exposure coming from viewing US movies. Copyright © 2016 Elsevier Inc.

Objective To assess whether exposure to movie smoking is associated with cigarette smoking among Argentinian adolescents. Study design School-based longitudinal study involving 33 secondary schools in Argentina. The sample included 2502 never smokers (average age at entry =12.5y), 1,700 (67.9%) of whom completed follow-up surveys 17 months later. Exposure to the top 100 grossing films for each year between 2009 and 2013 was assessed by content-coding films for tobacco, and then asking adolescents whether they had seen each of 50 titles, randomly selected from the larger pool, then parsing exposure into tertiles. Logistic regression models estimated adjusted odds ratio (AOR) for the following transitions: non-susceptible to susceptible never smoker, never smoker to ever smoker, and never smoker to current smoking (last 30 days). Results At follow-up, 34.4% of non-susceptible never smokers became susceptible, 24.1% reported having tried smoking, and 9.6% were current smokers. Most exposure to movie smoking was from US-produced films (average 60.3 minutes compared with only 3.4 minutes from Argentine films). Higher exposure to smoking in movies was significantly associated with increased odds of becoming susceptible (AOR1st vs 3rd tertile = 1.77, 95% confidence interval 1.30–2.41), of trying smoking (AOR1st vs 3rd tertile = 1.54, 1.14–2.08), and marginally associated with current smoking (AOR1st vs 3rd tertile = 1.54, 0.99–2.40). Exposure to smoking in US- or Argentine-produced films had similar associations. Conclusion In Argentina, exposure to smoking in the movies predicted future smoking transitions among early adolescents, with most exposure coming from viewing US movies. PMID:28029343

Background In diabetes mellitus, cigarette smoking is associated with increased risk of cardiovascular mortality and microvascular complications. We evaluated cigarette smoking in people with diabetes mellitus in a socio-economically deprived area. Methods We carried out a cross-sectional survey of people registered with diabetes mellitus at 29 general practices in inner London. Responses were analysed for 1,899 (64%) respondents out of 2,983 eligible. Results There were 1,899 respondents of whom 968 (51%) had never smoked, 296 (16%) were current smokers and 582 (31%) were ex-smokers. Smoking was more frequent in white Europeans (men 22%, women 20%), than in African Caribbeans (men 15%, women 10%) or Africans (men 8%, women 2%). Smoking prevalence decreased with age. Smokers were more likely to be living in rented accommodation (odds ratio, OR 2.02, 95% confidence interval 1.48 to 2.74). After adjusting for confounding, current smokers had lower SF-36 scores than subjects who had never smoked (mean difference in physical functioning score -5.6, 95% confidence interval -10.0 to -1.2; general health -6.1, -9.7 to -2.5). Current smokers were less likely to have attended a hospital diabetic clinic in the last year (OR 0.59, 0.44 to 0.79), and their hypertension was less likely to be treated (OR 0.47, 0.30 to 0.74). Conclusions Compared with non-smokers, smokers had lower socio-economic status and worse health status, but were less likely to be referred to hospital or treated for their hypertension. People with diabetes who smoke can be regarded as a vulnerable group who need more intensive support and treatment. PMID:12589709

Although most young adult smokers want to quit smoking, few can do so successfully. Increased understanding of reasons to quit in this age group could help tailor interventions, but few studies document reasons to quit in young adults or examine reasons to quit by smoker characteristics. In 2011-12, 311 current smokers (age 22-28, M=24.1; 48.9% male, 51.1% female; 50.4% daily smokers) from the Nicotine Dependence in Teens Study completed the Adolescent Reasons for Quitting scale. We assessed differences in the importance of 15 reasons to quit by sex, education, smoking frequency, quit attempt in the past year, perceived difficulty in quitting, and motivation to quit. We also examined differences between participants who discounted the importance of long-term health risks and those who acknowledged such risks. Concerns about getting sick or still smoking when older were considered very important by >70% of participants. Median scores were higher among daily smokers, those who had tried to quit or who expressed difficulty quitting, and those with strong motivation to quit. Discounters (14.5% of participants) were primarily nondaily, low-consumption smokers. Their Fagerström Test for Nicotine Dependence scores did not differ from non-discounters', and 11% (vs. 35.7% of non-discounters) were ICD-10 tobacco dependent. Novel smoking cessation interventions are needed to help young adult smokers quit by capitalizing on their health concerns. Discounters may need educational intervention to better understand the impact of even "light" smoking on their health before or in conjunction with quit interventions. Copyright © 2017 Elsevier Ltd.

The effects of smoking on central aortic pressures and the age-related increase in left ventricular mass (LVM) are largely unknown. We studied the relationship between smoking, arterial distensibility, central aortic pressures and left ventricular mass in two population-based studies. Data was obtained from two German population-based studies (KORA and SHIP, participants' ages 25-84 years). We identified 114 normotensive current smokers and 185 normotensive all-time non-smokers in KORA as well as 400 and 588 such individuals in SHIP. Echocardiographic LVM was obtained at baseline (T0) and follow-up after ten years (T1) in KORA and at follow-up (T1) in SHIP. Additionally, pulse-wave analysis-based central aortic pressure and augmentation index (AIx) were measured at T1 in KORA. Cross-sectional analysis, using KORA T0 and SHIP T1, revealed in both studies a higher covariate-adjusted LVM and left ventricular mass index (LVMI) in smokers as compared with non-smokers. Moreover, in the KORA T1 examination, the smokers demonstrated a more pronounced increase, relative to baseline, of LVM (+13.5%) and LVMI (+13.4%) compared to non-smokers (+8.59% and +8.65%; p=0.036 and 0.042, respectively). Additionally, at KORA T1 smokers had a higher central systolic blood pressure and higher AIx than non-smokers (p=0.012 and p=0.001, respectively). The difference in central aortic pressure due to enhanced and more prolonged wave reflection may explain our finding of a further pronounced increase in left ventricular wall thickness and mass over time in smokers.

Research demonstrates that nicotine dependence and depression are associated and that physical activity is effective in reducing depression symptoms. However, our understanding of the potential beneficial effects of physical activity on depression in current smokers is more limited. The purpose of this study was to examine whether physical activity moderates the association between nicotine dependence and depression in U.S. smokers. Cross-sectional. National Health and Nutrition Examination Survey 2005-2006. Four hundred forty-one current adult smokers. Participants wore an accelerometer for at least 4 days and completed questionnaires to assess nicotine dependence and depression. Effect modification and statistical interaction models were used. Both models were significant. With regard to the statistical interaction model, and after controlling for age, gender, race/ethnicity, education, comorbidity index, homocysteine, cotinine, total cholesterol, sedentary behavior, and vitamins C, D, and E, objectively measured physical activity moderated the association between nicotine dependence and depression (interaction variable: odds ratio = 3.43; 95% confidence interval: 1.02-11.51; p = .04). In this national sample of current smokers, physical activity moderated the association between nicotine dependence and depression. These results suggest that those individuals with nicotine dependence and who are less physically active are more likely to be depressed than what would be expected on the basis of the individual effects of nicotine and physical inactivity separately.
Fruit and vegetable intake and smoking cessation.

In cohort studies, fruit and vegetable (F&V) intake is associated with lower cardiovascular diseases (CVDs). Former smokers often have a higher F&V intake than current smokers. If a high intake of F&V precedes smoking cessation, the latter may explain the favorable association between F&V intake and CVD among smokers. The objective was to assess whether higher F&V intake precedes smoking cessation. The study population comprised 1056 male smokers from Lille (France) and Belfast (Northern Ireland) aged 50-59 years on inclusion in 1991. At baseline, participants completed self-administered questionnaires related to smoking habits, demographic, socioeconomic factors and diet. At the 10-year follow-up, smoking habits were assessed by mailed questionnaire. After 10 years, 590 out of 1056 smokers had quit smoking (70.7% of smoker in Lille and 37.8% in Belfast). After adjusting for center, consumption of F&V was associated with quitting (odds ratio (OR) for high versus low F&V intake: 1.73; 95% confidence interval (CI): (1.22-2.45); P-trend=0.002). After further adjustment for sociodemographic factors, body mass index and medical diet, the association was still statistically significant (OR: 1.59; 95% CI (1.12-2.27); P-trend = 0.01). In a model fully adjusted for age, smoking intensity, alcohol consumption and physical activity, the association was no longer significant (P = 0.14). Higher F&V intake precedes smoking cessation. Hence, smoking cessation could affect the causal interpretation of the association between F&V and CVD in smokers.

Issue addressed The smoking rate among male Chinese migrants in Australia is higher than among the general population. This study investigated the smoking rate of male Chinese restaurant workers in metropolitan Sydney, and explored factors associated with smoking and quitting. Methods A self-administered questionnaire survey was completed by Chinese workers in selected Chinese restaurants in metropolitan Sydney from October-December 2012. Eighty-nine Chinese restaurants were approached and 54 (61%) took part in the study. The questionnaire asked participants about their smoking status, knowledge of and attitudes to smoking and quitting as well as socio-demographic information. Multivariable logistic regression was built to assess the associated factors. Results Of the 382 participants who completed the survey, 171 (45%) were current smokers and 50% of current smokers wanted to quit smoking. Participants who spoke Mandarin, had lower English proficiency, did not realise environmental smoke harms children, did not prefer a smoke-free environment or had more than 50% of relatives or friends who smoked were more likely to be current smokers. Participants who were aged 18-29 years, did not understand the benefits of quitting smoking or did not prefer a smoke-free environment were less likely to want to quit. Conclusions Nearly 50% of male Chinese restaurant workers surveyed in this study were current smokers. Key factors associated with the participants' smoking or quitting status are: aged 18-29 years; speaking Mandarin; lower English literacy; and not knowing the dangers of smoking. So what? Tobacco control programs targetted at male Chinese restaurant workers that raise awareness of the harm caused by smoking and the benefits of quitting smoking are required to enhance intention to quit smoking within this population.

The effects of birth cohorts reflect the historical differences in physical and social environments. The objectives of the present study were to describe the tobacco consumption and to evaluate the behavioral trends with respect to smoking in three different birth cohorts of a population-based sample of elderly individuals. A series of three cross-sectional studies conducted with elderly individuals of 60-64 years of age interviewed in 2000 (birth cohort 1936-1940; n=427), 2006 (birth cohort 1942-1946; n=298) and 2011 (birth cohort 1947-1951; n=355) in a population-based sample from the city of São Paulo, Brazil. The interviewees were participating in a prospective cohort study entitled Health, Well-Being and Aging (Saúde, Bem-Estar e Envelhecimento [SABE]). Data on tobacco consumption were self-reported and interviewees were then classified as never smokers, former smokers or current smokers. Linear model for categorical data was used to test differences on tobacco consumption between three birth elderly cohorts. Men were more likely than women to be smokers. Being evangelical and having more schooling constituted protective factors against smoking. Regarding trends, the tobacco consumption of the men did not change in any of the three cohorts studied (p=0.7454), whereas there was an increase in the number of women smokers, principally former smokers, over the periods evaluated (p=0.0189). These results suggest that the anti-smoking policies implemented in Brazil were effective in women of this age group; however, different prevention strategies are required to target elderly men.

There is a strong dose-response relationship between smoking and risk of ischemic stroke in young women, but there are few data examining this association in young men. We examined the dose-response relationship between the quantity of cigarettes smoked and the odds of developing an ischemic stroke in men under age 50 years. The Stroke Prevention in Young Men Study is a population-based case-control study of risk factors for ischemic stroke in men ages 15 to 49 years. The χ 2 test was used to test categorical comparisons. Logistic regression models were used to calculate the odds ratio for ischemic stroke occurrence comparing current and former smokers to never smokers. In the first model, we adjusted solely for age. In the second model, we adjusted for potential confounding factors, including age, race, education, hypertension, myocardial infarction, angina, diabetes mellitus, and body mass index. The study population consisted of 615 cases and 530 controls. The odds ratio for the current smoking group compared with never smokers was 1.88. Furthermore, when the current smoking group was stratified by number of cigarettes smoked, there was a dose-response relationship for the odds ratio, ranging from 1.46 for those smoking <11 cigarettes per day to 5.66 for those smoking 40+ cigarettes per day. We found a strong dose-response relationship between the number of cigarettes smoked daily and ischemic stroke among young men. Although complete smoking cessation is the goal, even smoking fewer cigarettes may reduce the risk of ischemic stroke in young men. © 2018 American Heart Association, Inc.

Rationale: Former smoking history and chronic obstructive pulmonary disease (COPD) are potential risk factors for osteoporosis and fractures. Under existing guidelines for osteoporosis screening, women are included but men are not, and only current smoking is considered. Objectives: To demonstrate the impact of COPD and smoking history on the risk of osteoporosis and vertebral fracture in men and women. Methods: Characteristics of participants with low volumetric bone mineral density (vBMD) were identified and related to COPD and other risk factors. We tested associations of sex and COPD with both vBMD and fractures adjusting for age, race, body mass index (BMI), smoking, and glucocorticoid use. Measurements and Main Results: vBMD by calibrated quantitative computed tomography (QCT), visually scored vertebral fractures, and severity of lung disease were determined from chest CT scans of 3,321 current and ex-smokers in the COPDGene study. Low vBMD as a surrogate for osteoporosis was calculated from young adult normal values. Male smokers had a small but significantly greater risk of low vBMD (2.5 SD below young adult mean by calibrated QCT) and more fractures than female smokers. Low vBMD was present in 58% of all subjects, was more frequent in those with worse COPD, and rose to 84% among subjects with very severe COPD. Vertebral fractures were present in 37% of all subjects and were associated with lower vBMD at each Global Initiative for Chronic Obstructive Lung Disease stage of severity. Vertebral fractures were most common in the midthoracic region. COPD and especially emphysema were associated with both low vBMD and vertebral fractures after adjustment for steroid use, age, pack-years of smoking, current smoking, and exacerbations. Airway disease was associated with higher bone density after adjustment for other variables. Calibrated QCT identified more subjects with abnormal values than the standard dual-energy X-ray absorptiometry in a subset of subjects and correlated well with prevalent fractures. Conclusions: Male smokers, with or without COPD, have a significant risk of low vBMD and vertebral fractures. COPD was associated with low vBMD after adjusting for race, sex, BMI, smoking, steroid use, exacerbations, and age. Screening for low vBMD by using QCT in men and women who are smokers will increase opportunities to identify and treat osteoporosis in this at-risk population. PMID:25719895

Background: As exposure to tobacco smoke pollution (TSP) has been identified as a cause of premature death and disease in non-smokers, and studies have demonstrated that smoking in cars produces high levels of TSP, this study will investigate smokers’ rules for smoking in their cars, and predictors of car smoking rules, including potentially modifiable correlates. Methods: Data were drawn from nationally representative samples of current smokers from the International Tobacco Control Policy Evaluation Project surveys in France (2007), Germany (2007), and the Netherlands (2008). Smokers in France and Germany were asked about smoking rules in their cars, and smokers in the Netherlands were asked about smoking rules in cars carrying children. Results: In France and Germany, 59% and 52% of smokers respectively, allowed smoking in their cars. In the Netherlands, 36% of smokers allowed smoking in cars carrying children. Predictors of allowing smoking in cars included: being a daily vs. non-daily smoker, being younger vs. older age, having no (young) children in the home, being a heavier smoker, and allowing smoking in the home. In the Netherlands, smokers who agreed that TSP is dangerous to non-smokers were less likely to allow smoking in cars carrying children. Conclusion: Overall, a sizeable proportion of smokers allowed smoking in their cars across the three countries. Media campaigns with information about the dangers of TSP may increase the adoption of smoke-free cars. These media campaigns could target smokers who are most likely to allow smoking in cars.

Objectives Smoking of cigarettes or bidis (small, locally manufactured smoked tobacco) in India has likely changed over the last decade. We sought to document trends in smoking prevalence among Indians aged 15–69 years between 1998 and 2015. Design Comparison of 3 nationally representative surveys representing 99% of India's population; the Special Fertility and Mortality Survey (1998), the Sample Registration System Baseline Survey (2004) and the Global Adult Tobacco Survey (2010). Setting India. Participants About 14 million residents from 2.5 million homes, representative of India. Main outcome measures Age-standardised smoking prevalence and projected absolute numbers of smokers in 2015. Trends were stratified by type of tobacco smoked, age, gender and education level. Findings The age-standardised prevalence of any smoking in men at ages 15–69 years fell from about 27% in 1998 to 24% in 2010, but rose at ages 15–29 years. During this period, cigarette smoking in men became about twofold more prevalent at ages 15–69 years and fourfold more prevalent at ages 15–29 years. By contrast, bidi smoking among men at ages 15–69 years fell modestly. The age-standardised prevalence of any smoking in women at these ages was 2.7% in 2010. The smoking prevalence in women born after 1960 was about half of the prevalence in women born before 1950. By contrast, the intergenerational changes in smoking prevalence in men were much smaller. The absolute numbers of men smoking any type of tobacco at ages 15–69 years rose by about 29 million or 36% in relative terms from 79 million in 1998 to 108 million in 2015. This represents an average increase of about 1.7 million male smokers every year. By 2015, there were roughly equal numbers of men smoking cigarettes or bidis. About 11 million women aged 15–69 smoked in 2015. Among illiterate men, the prevalence of smoking rose (most sharply for cigarettes) but fell modestly among men with grade 10 or more education. The ex-smoking prevalence in men at ages 45–59 years rose modestly but was low: only 5% nationally with about 4 current smokers for every former smoker. Conclusions Despite modest decreases in smoking prevalence, the absolute numbers of male smokers aged 15–69 years has increased substantially over the last 15 years. Cigarettes are displacing bidi smoking, most notably among young adult men and illiterate men. Tobacco control policies need to adapt to these changes, most notably with higher taxation on tobacco products, so as to raise the currently low levels of adult smoking cessation. PMID:28588906
Cigarette smoking is associated with amplified age-related volume loss in subcortical brain regions.

Magnetic resonance imaging studies of cigarette smoking-related effects on human brain structure have primarily employed voxel-based morphometry, and the most consistently reported finding was smaller volumes or lower density in anterior frontal regions and the insula. Much less is known about the effects of smoking on subcortical regions. We compared smokers and non-smokers on regional subcortical volumes, and predicted that smokers demonstrate greater age-related volume loss across subcortical regions than non-smokers. Non-smokers (n=43) and smokers (n=40), 22-70 years of age, completed a 4T MRI study. Bilateral total subcortical lobar white matter (WM) and subcortical nuclei volumes were quantitated via FreeSurfer. In smokers, associations between smoking severity measures and subcortical volumes were examined. Smokers demonstrated greater age-related volume loss than non-smokers in the bilateral subcortical lobar WM, thalamus, and cerebellar cortex, as well as in the corpus callosum and subdivisions. In smokers, higher pack-years were associated with smaller volumes of the bilateral amygdala, nucleus accumbens, total corpus callosum and subcortical WM. Results provide novel evidence that chronic smoking in adults is associated with accelerated age-related volume loss in subcortical WM and GM nuclei. Greater cigarette quantity/exposure was related to smaller volumes in regions that also showed greater age-related volume loss in smokers. Findings suggest smoking adversely affected the structural integrity of subcortical brain regions with increasing age and exposure. The greater age-related volume loss in smokers may have implications for cortical-subcortical structural and/or functional connectivity, and response to available smoking cessation interventions.

The numbers of women smoking have risen 72.5% since 1990 with the increasing population - from 56,100 to 96,800 in 2012, reflecting an alarming situation in Hong Kong. The study aimed to describe the smoking behaviour, attitudes and associated factors among women in Hong Kong. A qualitative cross-sectional study involving semi-structured interview was conducted with Chinese women from five community centres in different districts in Hong Kong in 2010. A purposive sample of 73 female participants (24 current smokers, 20 ex-smokers and 29 never-smokers) were recruited. The 73 women were classified by their smoking status and age to form 15 focus groups. Most informants knew about the general health hazards of smoking, such as cancer and heart or respiratory diseases, but not about the female-specific health consequences of smoking. A few smokers considered smoking to be a weight control strategy, fearing a gain in weight if they gave up. Moreover, a few relied on smoking as a coping strategy to relieve negative emotions and stress. Additionally, a few smokers had misconceptions about giving up: that a loss of concentration would result, that continued smoking would not further affect their health as they had become desensitised to the chemicals in tobacco smoke or that quitting would harm their health. This study generates new knowledge about the behavior, attitudes, and experiences related to smoking of current female smokers, ex-smokers and non-smokers in Hong Kong, which is unique as a Chinese but highly westernized community but with a very low female smoking prevalence.

Introduction: Menthol is the only characterizing flavor in cigarettes that was not banned as part of the 2009 Family Smoking Prevention and Tobacco Control Act. This longitudinal study explores the role of menthol in smoking initiation and progression. Purpose (a) to examine young adult patterns of menthol cigarette use including switching between menthol and non-menthol and (b) to describe associations between these patterns of menthol use and cessation related intentions and behaviors. Additional data on the role of menthol in cigarettes on smoking uptake and maintenance is needed to inform proposed policy making at the local, state, and national levels. Methods: Using 3 time points from a longitudinal national sample of young adults aged 18–34 years (N = 267 smokers), patterns of menthol use over 1 year were defined among smokers as: (a) remained menthol smoker; (b) remained non-menthol smoker; (c) switched from menthol to non-menthol; and (d) switched from non-menthol to menthol. Associations were assessed between current menthol cigarette use and cessation intentions and behaviors. Results: Significant predictors of current menthol cigarette use at 1 year included initiation with menthol (OR = 8.26), Black race (OR = 23.60), and higher scores on the Allen menthol taste subscale (OR = 1.53). Menthol smokers were more likely to report intention to quit but no differences existed between menthol and non-menthol users in ever making a quit attempt. Conclusions: Most young adults stay with the product that they start smoking with. Menthol smokers were interested in quitting, but less interested in next 30-day action than non-menthol smokers.

To investigate whether associations of smoking with depression and anxiety are likely to be causal, using a Mendelian randomisation approach. Mendelian randomisation meta-analyses using a genetic variant (rs16969968/rs1051730) as a proxy for smoking heaviness, and observational meta-analyses of the associations of smoking status and smoking heaviness with depression, anxiety and psychological distress. Current, former and never smokers of European ancestry aged ≥16 years from 25 studies in the Consortium for Causal Analysis Research in Tobacco and Alcohol (CARTA). Binary definitions of depression, anxiety and psychological distress assessed by clinical interview, symptom scales or self-reported recall of clinician diagnosis. The analytic sample included up to 58 176 never smokers, 37 428 former smokers and 32 028 current smokers (total N=127 632). In observational analyses, current smokers had 1.85 times greater odds of depression (95% CI 1.65 to 2.07), 1.71 times greater odds of anxiety (95% CI 1.54 to 1.90) and 1.69 times greater odds of psychological distress (95% CI 1.56 to 1.83) than never smokers. Former smokers also had greater odds of depression, anxiety and psychological distress than never smokers. There was evidence for positive associations of smoking heaviness with depression, anxiety and psychological distress (ORs per cigarette per day: 1.03 (95% CI 1.02 to 1.04), 1.03 (95% CI 1.02 to 1.04) and 1.02 (95% CI 1.02 to 1.03) respectively). In Mendelian randomisation analyses, there was no strong evidence that the minor allele of rs16969968/rs1051730 was associated with depression (OR=1.00, 95% CI 0.95 to 1.05), anxiety (OR=1.02, 95% CI 0.97 to 1.07) or psychological distress (OR=1.02, 95% CI 0.98 to 1.06) in current smokers. Results were similar for former smokers. Findings from Mendelian randomisation analyses do not support a causal role of smoking heaviness in the development of depression and anxiety.

Benefit-cost analyses of tobacco regulations include estimates of the informed choice of smokers to continue smoking. Few studies have focused on subjective feelings associated with continued smoking. This study estimates how smoker discontent and regret relate to risk perceptions and health concerns. We analysed data from a 2015 nationally representative, online survey of 1284 US adult current smokers. Information was collected on regret, intention to quit, perceived addiction, risk perceptions and health concerns. Multivariate logistic regression adjusting for sociodemographics and health status was used to examine factors associated with smoker discontent. More than 80% of current smokers report high (22.5%) or very high (59.8%) discontent due to inability to quit, perceived addiction and regret about having started to smoke. Higher levels of discontent did not vary significantly by sex, age, race/ethnicity, education or income (adjusted odds ratios (AORs) 0.5-1.2). Compared with the smokers expressing low (5.9%) or very low (3.6%) discontent, those expressing higher levels of discontent perceived their health status as fair/poor (AOR=2.3), worried most of the time about lung cancer (AOR=4.6) and felt they were more likely to develop lung cancer in the future (AOR=5.1). The proportion of smokers who might be characterised as having a preference to continue smoking are greatly outnumbered by addicted, discontent and concerned smokers who want to quit and regret ever having started to smoke. These discontent smokers could have a substantial net welfare gain if new regulations helped them escape their concerns about the health effects from continuing smoking. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Measurement of exhaled carbon monoxide (ECO) has been used to confirm self-reported tobacco smoking. There is little data regarding ECO levels among Thai tobacco smokers by age. The objectives of this study were to determine ECO cutoff level to confirm tobacco smoking and to assess whether the cutoff level varies by age. During 2009 we evaluated 875 Thai volunteers aged 16-70 years, residing in Pathum Thani (central Thailand) and Khon Kaen (northeastern Thailand). Among the 875 volunteers, there were 584 non-smokers and 291 smokers. Each subject was interviewed and had their ECO level measured. The mean ECO level was 11.24 ppm among smokers and 2.25 ppm among non-smokers. The best ECO cutoff level to distinguish 291smokers from 584 non-smokers was 5 ppm (sensitivity 79.0%, specificity 89.9%).The optimal ECO cutoff level varied by age-group. For subjects aged 16-25 years, the best ECO cutoff level was 4 ppm (sensitivity 85.2%, specificity 77.5%) and for subject aged 26-70 years, the best ECO cutoff level was 5 ppm (sensitivity 79.4%, specificity 91.2%).These levels by age should be used among Thai subjects to determine smoking.
[Cigarette use among Israeli adolescents: why do they smoke?].

2007-03-01
Efforts to prevent adolescents from smoking have limited efficacy, with little understanding of why they smoke. We examine many of the factors which may influence a teenager's decision to start smoking. A self-completed questionnaire was distributed among pre-draft teenagers (age 16-18 years) with questions regarding current smoking habits as well as smoking habits of family members. Smokers were asked why they started, and attitudes regarding the dangers of smoking and anti-smoking legislation were examined. A total of 1067 questionnaires were completed (707 males, 360 females). In all, 25.7% were current smokers (26.2% of male and 21.1% of females; p=0.069), with smoking rates highest among those born in Middle Eastern countries and lowest among those born in Ethiopia. Those from single-parent families had a higher smoking rate (relative risk: 1.28), as did those with either parents or siblings who smoked. Parents who were smokers were more likely to tell their children not to smoke, while smoking teenagers were more likely to have been told by their parents not to smoke. Most smokers (58.2%) did not give a specific reason for smoking while 30.3% listed "peer pressure", 8.4% "parents smoking" and 3.1% "advertisements" as the major factor. Smokers were less likely to agree that smoking is harmful and more likely to oppose anti-smoking legislative measures. Many factors influence a teenager's decision to smoke, including cultural norms and habits of friends and family members. Educating both adolescents and those around them may help prevent smoking among this age group.

Background Smokers with greater knowledge of the health effects of smoking are more likely to quit and remain abstinent. Australia has communicated the causal association of smoking and blindness since the late 1990s. In March 2007, Australia became the first country to include a pictorial warning label on cigarette packages with the message that smoking causes blindness. The current study tested the hypothesis that the introduction of this warning label increased smokers’ knowledge of this important health effect. Methods Six waves of the International Tobacco Control Four Country Survey were conducted, as a telephone survey of 17,472 adult smokers in Australia, Canada, United Kingdom and the United States, with three waves before and three waves after the blindness health warning was introduced in Australia. The survey measured adult smokers’ knowledge that smoking causes blindness. Results Australian smokers were significantly more likely to report that smoking causes blindness, compared to Canadian, UK and US smokers, where there were neither health campaigns nor health warnings labels about blindness. After the introduction of the blindness warning, Australian smokers were more likely than before the blindness warning to report that they know that smoking causes blindness (62 versus 49 per cent; OR = 1.68, 95% CI: 1.03, 2.76, p = 0.04). In Australia, smokers aged over 55 years were less likely than those aged 18 to 24 to report that smoking causes blindness (OR = 0.43; 95% CI: 0.29, 0.62, p < 0.001). Conclusion While more smokers report that smoking causes blindness in Australia compared to other countries, which have not had national social marketing campaigns, further gains in knowledge were found after pictorial warning labels were introduced in Australia. Findings suggest there is still a need to educate the public about the causal association of smoking and blindness. More education may be needed to redress the knowledge gap in older Australian smokers as the incidence of age-related macular degeneration increases with age. PMID:22882362

Prenatal smoking is a preventable risk factor for poor perinatal outcomes and is more prevalent in pregnant smokers of low socioeconomic status (SES). We describe the intervention model and factors associated with quitting from the Pittsburgh STOP Program, an evidence-informed dissemination intervention for low-SES pregnant smokers. STOP is delivered in community health care clinics serving economically disadvantaged women. Participants were 856 pregnant women who were current smokers (93%) and recent quitters (7%). Most were white (59%) or black (35%), single (74%), young (mean age = 25), and experiencing an unplanned pregnancy (84%); 90% were insured by Medicaid/uninsured. An evidence-informed intervention for community pregnant women was delivered individually in a single-group pre-post evaluation design. Measures were demographics, participation and retention, smoking status, satisfaction, and cost. Analyses included descriptive statistics and logistic regression. Participants attended an average of 4.7 sessions. Dropout rate after the first session was 5%. Over 11% of smokers quit; 48% of preenrollment spontaneous quitters remained abstinent. Factors significantly associated with quitting included race, mother's age, nicotine dependence, and number of sessions attended. STOP is a community program with self-selected participants and no control group. Low-income pregnant smokers will engage in an evidence-informed cessation program tailored for this group, with quit rates that compare to controlled research results.

The use of electronic cigarettes (EC) has risen exponentially over the past decade, including among never smokers, and ECs are now the most popular tobacco product among teenagers in the US. While, EC manufacturers utilize numerous marketing strategies to target both smokers and non-smokers, it is unclear how perceptions and behaviors differ between these two groups. We conducted a survey of 320 adults either via online surveys or in Baltimore vape shops to determine demographics, behaviors, perceptions, and motivations underlying use of ECs. Our survey respondents were predominantly young, Caucasian males, 74% of whom identified themselves as former smokers, while 20% identified as current smokers and 6% were never smokers. Former smokers reported a longer history of EC use and higher nicotine concentrations than current smokers. For former and current smokers, the primary motivation for EC use was assistance to quit smoking, and nearly half indicated that they plan to reduce their nicotine concentration and eventually quit using ECs. Among former smokers, self-reports on use and measures of dependence were consistent with nicotine replacement as their primary motivation. The majority of former and current smokers also reported that their respiratory health had improved as a result of EC use, although this effect was stronger for former smokers. Never smokers reported less frequent EC use and dependence compared to former and current smokers. Their motivations for use were more commonly for enjoyment and popularity, and they displayed a reduced desire to eventually quit using ECs. These responses provide insight into the underlying thoughts and behaviors of smoking and non-smoking EC users and also suggest that never smoking EC users are an emerging demographic with different motivations and perceptions than those of current and former smokers.

Although established adult smokers with long histories of nicotine dependence have lower neural tissue volume than non-smokers, it is not clear if lower regional brain volume is also observed in younger, less established smokers. The primary goal of this study was to investigate neural tissue volume in a large group of smokers and non-smokers, with a secondary goal of measuring the impact of age on these effects. We used voxel-based morphometry to compare regional gray matter volume in 118 individuals (59 smokers, 59 age- and gender-matched non-smokers). Younger smokers had significantly lower gray matter volume in the left thalamus and the left amygdala than their non-smoking peers (family-wise error-corrected clusters, P < 0.05). There was no correlation between smoking use variables and tissue volume among younger smokers. Established smokers had significantly lower gray matter volume than age-matched non-smokers in the insula, parahippocampal gyrus and pallidum. Medial prefrontal cortex gray matter volume was negatively correlated with pack-years of smoking among the established smokers, but not the younger smokers. These data reveal that regional tissue volume differences are not limited exclusively to established smokers. Deficits in young adults indicate that cigarette smoking may either be deleterious to the thalamus and amygdala at an earlier age than previously reported, or that pre-existing differences in these areas may predispose individuals to the development of nicotine dependence.

The metabolic syndrome: prevalence and associated lifestyles in Japanese workingmen.
Kawada, Tomoyuki; Okada, Kyoji
2006-01-01
The aim of this study was to examine the relation of lifestyle to the metabolic syndrome in Japanese male workers. The association of 6 lifestyle factors with the metabolic syndrome and the prevalence of the metabolic syndrome, as defined by the modified International Diabetes Federation criteria for Japanese people, were evaluated in 4941 men at a workplace participating in the annual health examination mandated by law; the subjects ranged in age from 36 to 60 years. The overall prevalence of the metabolic syndrome in the sample was 9.1%. The prevalence was the highest in subjects aged 46-50 years. The odds ratios (95% confidence interval) of the metabolic syndrome in current smokers and ex-smokers compared with non-smokers were 1.381 (1.088-1.752) (P=.008) and 1.812 (1.365-2.407) (P<.001), respectively. In contrast, no preventive effect of alcohol on the occurrence of the metabolic syndrome was noted.
Impact of cigarette smoking on utilization of nursing home services.

Few studies have examined the effects of smoking on nursing home utilization, generally using poor data on smoking status. No previous study has distinguished utilization for recent from long-term quitters. Using the Health and Retirement Study, we assessed nursing home utilization by never-smokers, long-term quitters (quit >3 years), recent quitters (quit ≤3 years), and current smokers. We used logistic regression to evaluate the likelihood of a nursing home admission. For those with an admission, we used negative binomial regression on the number of nursing home nights. Finally, we employed zero-inflated negative binomial regression to estimate nights for the full sample. Controlling for other variables, compared with never-smokers, long-term quitters have an odds ratio (OR) for nursing home admission of 1.18 (95% CI: 1.07-1.2), current smokers 1.39 (1.23-1.57), and recent quitters 1.55 (1.29-1.87). The probability of admission rises rapidly with age and is lower for African Americans and Hispanics, more affluent respondents, respondents with a spouse present in the home, and respondents with a living child. Given admission, smoking status is not associated with length of stay (LOS). LOS is longer for older respondents and women and shorter for more affluent respondents and those with spouses present. Compared with otherwise identical never-smokers, former and current smokers have a significantly increased risk of nursing home admission. That recent quitters are at greatest risk of admission is consistent with evidence that many stop smoking because they are sick, often due to smoking.

To examine the prevalence and correlates of internet cigarette purchasing among adult smokers. Analysis of internet purchasing in data from a population based telephone survey of New Jersey households. Logistic regression was used to determine factors associated with internet cigarette purchasing, adjusting for year, demographic, and smoking behaviour variables. 3447 current cigarette smokers pooled from three cross sectional surveys conducted in 2000, 2001, and 2002. Ever purchasing tobacco and usually buying cigarettes via the internet. Among all current cigarette smokers, ever having purchased tobacco via the internet increased from 1.1% in 2000 to 6.7% in 2002 and usually buying cigarettes via the internet increased from 0.8% in 2000 to 3.1% in 2002. Among current cigarette smokers with internet access, ever having purchased tobacco via the internet was higher among those who reported smoking 31 or more cigarettes per day (adjusted odds ratio (OR) 3.9, 95% confidence interval (CI) 1.5 to 10.2) and those without a past year quit attempt (adjusted OR 1.8, 95% CI 1.1 to 3.0). Usually purchasing cigarettes via the internet was higher among those aged 45-64 years (adjusted OR 4.4, 95% CI 1.1 to 17.1) and who reported having their first cigarette < or = 30 minutes after waking (adjusted OR 3.3, 95% CI 1.2 to 9.2). Although higher prices are known to reduce the demand for cigarettes, internet cigarette purchasing is likely to weaken this effect, particularly among heavy, more dependent smokers who are less interested in quitting.
[Prevalence and user profile of electronic cigarettes in Spain (2014)].

To describe the prevalence and user profile of electronic cigarettes among Spanish adults and evaluate the potential dual use of these devices with combustible or conventional tobacco in 2014 in Spain. Cross-sectional study of a representative sample of the Spanish adult (16-75 years old) population (n=1,016). A computer-assisted telephone survey was conducted in 2014. The prevalence and 95% confidence intervals (95% CI) for the use of electronic cigarettes stratified by gender, age, tobacco consumption and social status were calculated. The sample was weighted and a logistic regression model adjusted to obtain the crude odds ratios (OR) adjusted by gender, age and social status. 10.3% (95% CI: 8.6-12.4) of the Spanish adult population stated being ever users of electronic cigarettes (2% current users, 3.2% past users and 5.1% experimental users). Among current electronic cigarette users, 57.2% also smoked combustible or conventional tobacco, 28% had never smoked and 14.8% were former smokers. The prevalence of electronic cigarette use was higher in the younger population (adjusted OR=23.8; 95% CI: 2.5-227.7) and smokers of combustible tobacco (adjusted OR=10.1; 95% CI: 5.8-17.5). The use of electronic cigarettes in Spain is scarce and is most prevalent among young people and tobacco smokers. Nevertheless, one out of four current electronic cigarette users have never smoked. Hence, the regulation of these devices should be reinforced to avoid a possible gateway to nicotine products among never smokers. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U.

Many patients with cancer use electronic cigarettes (e-cigarettes), yet little is known about patterns and reasons for use. Using cross-sectional baseline data from a randomized controlled trial, we aimed to describe prevalence and correlates of e-cigarette use, frequency of use, and reasons for use among smokers recently diagnosed with cancer. Participants (n = 302) included adults (age ≥18 years) recently diagnosed with varied cancer types who smoked ≥1 cigarette within the past 30-d from two US academic medical centers. Participants reported ever and current e-cigarette use, and current e-cigarette users reported days of e-cigarette use and the main reason for use. We compared current, former, and never e-cigarette users by sociodemographics, cancer type, medical comorbidities, smoking behaviors, attitudes, and emotional symptoms, and described use among current e-cigarette users. Of smokers recently diagnosed with cancer, 49% (n = 149) reported ever e-cigarette use and 19% (n = 56) reported current use. Of current e-cigarette users, 29% (n = 16) reported daily use. Current e-cigarette users did not differ from former and never e-cigarette users by cancer type, smoking behaviors, or emotional symptoms. Women were more likely to be current users than never users, and current e-cigarette users had less education than former users. Most current e-cigarette users reported using them to help quit smoking (75%). One in five smokers with cancer report current e-cigarette use, but most are not using e-cigarettes daily. The majority report using e-cigarettes to quit smoking. E-cigarette use by patients with cancer appears to reflect a desire to quit smoking. © 2018 The Authors.

Background Presenting to primary care with potential cancer symptoms is contingent on one’s ability to recognize potentially serious symptoms. We investigated differences between smokers and non-smokers in symptoms experienced, awareness and consulting of potential respiratory, head and neck cancer symptoms. Methods Smokers and non-smokers aged over 50 from Yorkshire general practice lists were sent a postal questionnaire asking about symptoms, consulting and awareness of cancer symptoms. Data were analysed using STATA14. Results Response rate after one reminder was 30.5% (1205/3954). Smoking status was associated with experience of cough (p<0.001), breathlessness (p = 0.002) and tiredness (p = 0.004) with smokers (25.8% of population) more likely than never-smokers (53.6% of population) to experience all three symptoms (cough OR = 2.56;95%CI[1.75–3.75], breathlessness OR = 2.39;95%CI[1.43–4.00], tiredness OR = 1.57;95%CI[1.12–2.19]). Smoking status was associated with awareness of breathlessness as a potential cancer symptom (p = 0.035) and consulting for cough (p = 0.011) with smokers less likely to consult than never-smokers (OR = 0.37;95% CI[0.17–0.80]). Conclusion Our findings suggest that current smokers are more likely to experience cough, breathlessness and tiredness, but are less likely to consult for cough than never-smokers. To increase cancer awareness and promote consulting among smokers, innovative interventions improving symptom recognition and empowering smokers to seek help are required. PMID:28846706

Objectives To examine the prevalence of electronic(e)-cigarette use, prevalence of e-cigarette and tobacco use by age, and associations of e-cigarette use with sociodemographic characteristics, tobacco and cannabis use among young people in Wales. Design Data from two nationally-representative cross-sectional surveys undertaken in 2013–2014. Logistic regression analyses, adjusting for school-level clustering, examined sociodemographic characteristics of e-cigarette use, and associations between e-cigarette use and smoking. Setting Primary and secondary schools in Wales. Participants Primary-school children aged 10–11 (n=1601) and secondary-school students aged 11–16 (n=9055). Results Primary-school children were more likely to have used e-cigarettes (5.8%) than tobacco (1.6%). Ever use of e-cigarettes remained more prevalent than ever use of tobacco until age 14–15. Overall, 12.3% of secondary-school students (aged 11–16) reported ever using e-cigarettes, with no differences according to gender, ethnicity or family affluence. The percentage of ‘never smokers’ reporting having used e-cigarettes was 5.3% at age 10–11 to 8.0% at age 15–16. The proportion of children who had ever used an e-cigarette and reported currently smoking increased from 6.9% among 10–11 year olds to 39.2% in 15–16 year olds. Only 1.5% (n=125) of 11–16 year-olds, including 0.3% of never smokers, reported regular e-cigarette use (use at least once a month). Current weekly smokers were 100 times more likely than non-smokers to report regular e-cigarette use (relative risk ratio (RRR=121.15; 95% CI 57.56 to 254.97). Regular e-cigarette use was also more likely among those who had smoked cannabis (RRR 53.03; 95% CI 38.87 to 80.65). Conclusions Many young people (including never-smokers) have tried e-cigarettes. However, regular use is less common, and is associated with tobacco cigarette use. Longitudinal research is needed to understand age-related trajectories of e-cigarette use and to understand the temporal nature of relationships between e-cigarette and tobacco use. PMID:25877272

The purpose of the present investigation is to compare the presence and number of periodontal pathogens in the subgingival microbiota of smokers versus never-smokers with chronic periodontitis and matched probing depths (PDs) using real-time polymerase chain reaction (RT-PCR). Forty current smokers and 40 never-smokers, matched for age, sex, and mean PD of sampling site, were included in this investigation. A full-mouth periodontal examination was performed, and a pooled subgingival plaque sample was collected from the deepest site in each quadrant of each participant. To confirm smoking status, expired carbon monoxide (CO) concentrations were measured with a CO monitor. The presence and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola were determined using RT-PCR. Smokers had greater overall mean PD (P = 0.001) and attachment loss (P = 0.006) and fewer bleeding on probing sites (P = 0.001). An association was observed between smoking status and the presence of A. actinomycetemcomitans (P <0.001). The counts of A. actinomycetemcomitans (P <0.001), P. gingivalis (P = 0.042), and T. forsythia (P <0.001) were significantly higher in smokers. Smokers showed significantly greater amounts of P. gingivalis, A. actinomycetemcomitans, and T. forsythia than never-smokers. There was a significant association between smoking and the presence of A. actinomycetemcomitans.

1 Single dose studies of theophylline kinetics were compared in groups of young and elderly smokers and non-smokers to assess the effect of age on theophylline absorption and the effect of smoking on drug metabolising enzyme activity in old age. 2 The rate and extent of absorption was not affected by age. Distribution and elimination kinetics were similar in young and elderly non-smokers. 3 In young subjects the elimination half-life of theophylline was shorter and clearance was significantly greater in smokers than in non-smokers. 4 In the elderly mean elimination half-life was significantly shorter in smokers and their plasma clearance was 40% higher than in non-smokers. The statistical difference for clearance was at the 7% level of significance. 5 These data indicate that ageing per se does not affect theophylline elimination and also that induction of theophylline metabolism due to smoking occurs in old age. Smoking is a variable that should be taken account of when assessing drug metabolism in elderly patients. PMID:7426272

Electronic nicotine delivery system (ENDS) use has increased rapidly in the U.S. in recent years. The availability and use of ENDS raise new issues for public health practice and tobacco regulation, as it is unknown whether patterns of ENDS use enhance, deter, or have no impact on combustible tobacco product use. This study assessed past-month, lifetime, and frequency of ENDS use among current, former, and never adult cigarette smokers. Data were analyzed from the 2014 Styles, a national consumer-based probability-based web panel survey of U.S. adults aged ≥18 years (n=4,269) conducted during June and July. Lifetime ENDS users were defined as those who reported having used ENDS ≥1 day in their lifetime. Past-month ENDS users were defined as those who reported using ENDS in the past 30 days. In 2014, overall lifetime and past-month ENDS use was 14.1% and 4.8%, respectively. By smoking status, 49.5% of current, 14.7% of former, and 4.1% of never cigarette smokers had used ENDS in their lifetime, whereas 20.6% of current, 4.0% of former, and 0.8% of never smokers used ENDS in the past month. Among current and former cigarette smokers who ever used ENDS, 44.1% and 44.7% reported using ENDS >10 days in their lifetime, respectively. Because the effect ENDS use has on combustible tobacco products use is unknown, and lifetime and past-month ENDS use is more common among current than former or never smokers, continued surveillance of ENDS use among adults is critical to programs and policies.

Smokers' attitudes and support for e-cigarette policies and regulation in the USA.
Wackowski, Olivia A; Delnevo, Cristine D

In April 2014, the Food and Drug Administration (FDA) proposed a rule to extend its tobacco regulatory authority to e-cigarettes, which have been unregulated and growing in use since their 2006-2007 US introduction. The FDA will issue a final rule based on comments and data received from researchers, tobacco companies and the public. We aimed to present data about current smokers' awareness of and attitudes towards potential e-cigarette regulation and various policies in the USA. We conducted a cross-sectional online e-cigarette focused survey of 519 adult current smokers in April 2014, before the FDA's proposed rule was announced. Participants were recruited from a private research panel (GFK's Knowledge Networks) designed to be representative of the US population. The majority of respondents (62.5%) did not know that e-cigarettes are unregulated by the FDA but agreed that e-cigarettes should be regulated by the FDA for safety and quality (83.5%), carry warning labels about their potential risks (86.6%) and have the same legal age of sale as other tobacco (87.7%). Support was similarly high among current e-cigarette users. Support was substantial though lower overall for policies to restrict e-cigarette indoor use (41.2%), flavouring (44.3%) and advertising (55.5%), and was negatively associated with current e-cigarette use. Support for many e-cigarette regulatory policies is strong among smokers, including for policies that the FDA has recently proposed and potential future regulations. States considering indoor e-cigarette restrictions should know that a substantial number of current smokers support such regulations. Published by the BMJ Publishing Group Limited.

Characterizing electronic cigarette (e-cigarette) use patterns is important for guiding tobacco regulatory policy and projecting the future burden of tobacco-related diseases. Few studies have examined patterns of e-cigarette use in individuals with cardiovascular disease (CVD). We examined e-cigarette use in adults aged 18 to 89 years with a history of CVD, using data from the 2014 National Health Interview Survey. We investigated associations between ever and current e-cigarette use and smoking with multivariable logistic regression. In a secondary analysis, we modeled the association between e-cigarette use and a quit attempt over the past year. Former smokers with CVD who quit smoking within the past year showed 1.85 (95% confidence interval, 1.03, 3.33) times the odds of having ever used e-cigarettes as compared with those who reported being "some days" current smokers. Current smokers who attempted to quit smoking within the past year showed significantly increased odds of ever having used e-cigarettes (odds ratio, 1.70; 95% confidence interval, 1.25, 2.30) and currently using e-cigarettes (odds ratio, 1.97; 95% confidence interval, 1.32, 2.95) as compared with smokers who had not attempted to quit over the past year. Individuals with CVD who recently quit smoking or reported a recent quit attempt were significantly more likely to use e-cigarettes than current smokers and those who did not report a quit attempt. Our findings may indicate that this population is using e-cigarettes as an aid to smoking cessation. Characterizing emerging e-cigarette use behaviors in adults with CVD may help to inform outreach activities aimed at this high-risk population. © 2018 The Authors.

While some smokers use e-cigarettes and stop smoking, a substantial proportion try e-cigarettes and later discontinue or use them concurrently with smoking (current dual users). The aim was to assess factors associated with ongoing e-cigarette use and discontinuation among smokers. Secondary analysis of data of 1489 currently smoking adults, 18 and above, from a GB population-based online survey conducted in March 2016. A multivariable logistic regression assessed motivation to stop smoking among never e-cigarette users, past triers (

The social-contextual model of tobacco control and the potential mechanisms of the maintenance or cessation of smoking behavior among disadvantaged women, including rural residents, have yet to be comprehensively studied. The purpose of this study was to determine the association between selected individual, interpersonal, workplace, and neighborhood characteristics and smoking status among women in Appalachia, a US region whose residents experience a disproportionate prevalence of tobacco-related health disparities. These findings may assist in efforts to design and test scientifically valid tobacco control interventions for this and other disadvantaged populations. Women, 18 years of age and older, residing in three rural Ohio Appalachian counties, were recruited using a two-phase address-based sampling methodology for a cross-sectional interview-administered survey between August 2012 and October 2013 (N=408). Multinomial logistic regression was employed to determine associations between select multilevel factors (independent variables) and smoking status (dependent variable). The sample included 82 (20.1%) current smokers, 92 (22.5%) former smokers, and 234 (57.4%) women reporting never smoking (mean age 51.7 years). In the final multivariable multinomial logistic regression model, controlling for all other significant associations, constructs at multiple social-contextual levels were associated with current versus either former or never smoking. At the individual level, for every additional year in age, the odds of being a former or never smoker increased by 7% and 6% (odds ratio (OR) (95% confidence interval(CI)): 1.07 (1.0-1.11) and 1.06 (1.02-1.09)), respectively, as compared to the odds of being a current smoker. With regard to depression, for each one unit increase in the Center for Epidemiologic Studies Depression Scale score, the odds of being a former or never smoker were 5% and 7% lower (OR(95%CI): 0.95(0.91-0.999) and 0.93(0.88-0.98)), respectively. Five interpersonal factors were associated with smoking status. As the social influence injunctive norm score increased by one unit, indicating perception of smoking to be more acceptable, the odds of being a former or never smoker decreased by 23% and 30%, respectively. For every one unit increase in the social participation score, indicating past-year engagement in one additional activity type, the odds of being a former or never smoker increased by 17% and 36%, respectively. For every 10% increase in the percentage of social ties in the participant's advice network who smoked, the odds of being a former or never smoker were 24% and 28% less, respectively. For every 0.1 unit increase in the E/I index, indicating increasing homophily on smoking in one's social network, the odds of being a former or never smoker were 20% and 24% less, respectively, in the time network, and 18% and 20% less, respectively, in the advice network. At the neighborhood level, for every one unit increase in neighborhood cohesion score, indicating increasing cohesion, the odds of being a former smoker or never smoker were 12% and 14% less, respectively. These findings indicate that a social-contextual approach to tobacco control may be useful for narrowing a widening trajectory of smoking disparity for rural women. Interpersonal context, in particular, must be considered in the development of culturally targeted cessation interventions for Ohio Appalachian women.

The aim of this study was to analyze the influence of active and passive smoking on cardiorespiratory responses in asymptomatic adults during a sub-maximal-exertion incremental test. The participants (n = 43) were divided into three different groups: active smokers (n = 14; aged 36.5 ± 8 years), passive smokers (n = 14; aged 34.6 ± 11.9 years) and non-smokers (n = 15; aged 30 ± 8.1 years). They all answered the Test for Nicotine Dependence and underwent anthropometric evaluation, spirometry and ergospirometry according to the Bruce Treadmill Protocol. VO2max differed statistically between active and non-smokers groups (p < 0.001) and between non-smokers and passive group (p=0.022). However, there was no difference between the passive and active smokers groups (p=0.053). Negative and significant correlations occurred between VO2max and age (r = - 0.401, p = 0.044), percentage of body fat (r = - 0.429, p = 0.011), and waist circumference (WC) (r = - 0.382, p = 0.025). VO2max was significantly higher in non-smokers compared to active smokers and passive smokers. However, the VO2max of passive smokers did not differ from active smokers.

Objectives We aimed to conduct culturally-based participatory research to assess cultural and belief contexts for smoking behaviours within Mandarin and Cantonese communities. Outcome variables were smoking-related knowledge, smoking patterns, attitudes and beliefs, and perceived barriers and facilitators to successful cessation. Design A community-based approach was applied involving smokers, community key-informants and professionals in study design and implementation. Initially, focus groups were conducted and findings were used to develop study instrument. Participants responded once to study questionnaire after informed consent. Setting Community based in the Greater Vancouver Area, Canada. Participants 16 Chinese smokers participated in focus groups and subsequently, 167 current Chinese immigrant (137 males and 30 females) smokers from Mandarin and Cantonese communities, recruited with the help of community agencies and collaborating physicians, were enrolled in a cross-sectional study. Results We found that a majority believed smoking was harmful on their health. Younger smokers (<35 years of age) did not mind smoking in front of young children compared to older smokers (≥35 years of age) (p<0.001). People with high school or lower levels of education believed that they would benefit more from smoking than suffering from withdrawal symptoms compared to better educated smokers (p<0.05). Mandarin smokers were significantly more likely to encourage others to quit than Cantonese smokers (p<0.05). Many indicated not receiving adequate support from care providers and lack of access to culturally and linguistically appropriate cessation programmes impacted on their ability to quit smoking. Conclusions Our study highlighted the importance of tobacco beliefs and perceptions among Mandarin and Cantonese speaking immigrants with limited access to healthcare information and for younger smokers whose attention to health consequences of smoking may be limited as well. Study participants were generally aware of the health risks and were willing to quit. Access to appropriate cessation programmes would fulfil their willingness. PMID:25649211

Tremor is among the acute effects of nicotine exposure. Published studies have focused on smoking-related postural (static) hand tremor rather than kinetic tremor (tremor during hand use), and gender differences in smoking-related tremor have not been examined. In a group of adults who were sampled from a population (mean ± SD = 65.7 ± 11.5 years, range = 18 - 92 years), the investigator assessed whether the severity of postural and kinetic tremors differed in smokers versus non-smokers, and whether this difference was influenced by gender. Twenty-seven (9.9%) of 273 subjects were current smokers. Greater tremor was observed in smokers than non-smokers during a variety of activities (drawing a spiral, using a spoon, finger-nose-finger maneuver, all p < 0.05) and smokers had a higher total tremor score than non-smokers (5.15 ± 3.06 vs. 3.41 ± 2.88, p < 0.01), even after adjusting for age, caffeine intake and other potential confounding factors. The difference between smokers and non-smokers in terms of hand tremor was more apparent in women than in men. In women, the number of cigarettes smoked on the day of testing was weakly correlated with the total tremor score (r = 0.17, p = 0.03). In summary, smokers had more kinetic hand tremor than non-smokers. This difference between smokers and non-smokers was more apparent in women than in men. These results suggest that smoking habits should be considered carefully in order to avoid over- or underestimating the effects of occupational and non-occupational exposures to other tremor-producing neurotoxins.

Many studies have reported brain volume changes in smokers. However, the volume differences of grey matter (GM) and white matter (WM) in young and middle-aged male smokers with different lifetime tobacco consumption (pack-years) remain uncertain. To examine the brain volume change, especially whether more pack-years smoking would be associated with smaller gray matter and white matter volume in young and middle-aged male smokers. We used a 3T MR scanner and performed Diffeomorphic anatomical registration through exponentiated lie algebra (DARTEL)-based voxel-based morphometry on 53 long-term male smokers (30.72 ± 4.19 years) and 53 male healthy non-smokers (30.83 ± 5.18 years). We separated smokers to light and heavy smokers by pack-years and compared brain volume between different smoker groups and non-smokers. And then we did analysis of covariance (ANCOVA) between smokers and non-smokers by setting pack-years as covariates. Light and heavy smokers all displayed smaller GM and WM volume than non-smokers and more obviously in heavy smokers. The main smaller areas in light and heavy smokers were superior temporal gyrus, insula, middle occipital gyrus, posterior cingulate, precuneus in GM and posterior cingulate, thalamus and midbrain in WM, in addition, we also observed more pack-years smoking was associated with some certain smaller GM and WM volumes by ANCOVA. Young and middle-aged male smokers had many smaller brain areas than non-smokers. Some of these areas' volume had negative correlation with pack-years, while some had not. These may due to different pathophysiological role of smokings. © 2015 John Wiley & Sons Ltd.

While aging is unavoidable, the aging mechanism is still unclear because of its complexity. Smoking causes premature death and is considered as an environmental aging accelerator. In the present study, we focused on the influence of smoking to the serum concentration of anti-aging protein α-klotho (αKl) and the β-klotho-associated protein fibroblast growth factor (FGF)-21 in men. Subjects consisted of apparently healthy men over 40 years of age who underwent health examination. Physical and biochemical parameters, including the levels of several cytokines and growth factors, were obtained from the subjects. Among middle-aged men (46.1 ± 5.1 years), serum levels of FGF-21, soluble αKl (sαKl), and inflammation-related cytokine interleukin (IL)-6 were significantly higher in smokers than in never-smokers. Serum levels of FGF-21 increased and correlated with alanine transaminase, γ guanosine-5'-triphosphate, and total cholesterol only in smokers, suggesting FGF-21 as a metabolic disorder-related factor in smokers. In aged men (60.3 ± 1.7 years), although the serum levels of sαKl in never-smokers were low, smokers showed highly increased serum levels of sαKl. Serum levels of sαKl was correlated with IL-6 in middle-aged never-smokers, suggesting sαKl regulates IL-6. However, this correlation was disrupted in smokers and aged men.

Cigarette smoking is a known risk factor for cardiovascular disease (CVD), but the association between smoking and blood pressure is unclear. Thus, the current study examined the association between cigarette smoking and blood pressure in men. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and pulse pressure (PP) were examined using digital blood pressure measuring device, and smoking status was determined with China National Health Survey. The ANCOVA showed that the adjusted DBP and MAP were lower in current smokers versus nonsmokers and the adjusted SBP was lower in current smokers versus former smokers (P < 0.05). Additionally, the adjusted PP tend to be decreased steadily as the pack·years increased in current smokers. In a fully adjusted logistic regression model, former smokers had increased ORs (95% CI) of 1.48 (1.01, 2.18) of hypertension and current smokers had not increased ORs (95% CI) of 0.83 (0.61, 1.12), compared with never smokers. The findings revealed that the adjusted blood pressure were lower in current smokers versus nonsmokers and former smokers. No significant dose-dependent effect of current smoking on blood pressure indices except PP was observed. Smoking cessation was significantly associated with an increased risk of hypertension. However, current smoking was not a risk factor of hypertension.

Tobacco use is the world's leading cause of preventable morbidity and mortality, resulting in nearly 6 million deaths each year (1). Smoked tobacco products, such as cigarettes and cigars, are the most common form of tobacco consumed worldwide (2), and most tobacco smokers begin smoking during adolescence (3). The health benefits of quitting are greater for persons who stop smoking at earlier ages; however, quitting smoking at any age has health benefits (4). CDC used the Global Youth Tobacco Survey (GYTS) data from 61 countries across the six World Health Organization (WHO) regions from 2012 to 2015 to examine the prevalence of current tobacco smoking and desire to quit smoking among students aged 13-15 years. Across all 61 countries, the median current tobacco smoking prevalence among students aged 13-15 years was 10.7% (range = 1.7%, Sri Lanka to 35.0%, Timor-Leste). By sex, the median current tobacco smoking prevalence was 14.6% among males (range = 2.9%, Tajikistan to 61.4%, Timor-Leste) and 7.5% among females (range = 1.6%, Tajikistan to 29.0%, Bulgaria). In the majority of countries assessed, the proportion of current tobacco smokers who desired to quit smoking exceeded 50%. These findings could be used by country level tobacco control programs to inform strategies to prevent and reduce youth tobacco use (1,4).
Schizophrenia, smoking status, and performance on the matrics Cognitive Consensus Battery.
Reed, Alexandra C; Harris, Josette G; Olincy, Ann

Cognitive deficits and high rates of nicotine dependence are consistently documented in the schizophrenia literature. However, there is currently no consensus about how regular smoking influences cognition in schizophrenia or which cognitive domains are most affected by chronic smoking. Previous studies have also failed to disambiguate the effects of chronic nicotine from those of acute exposure. The current study uses a novel approach to testing nicotine addicted patients at a time-point between acute enhancement and withdrawal and implements the MATRICS Cognitive Consensus Battery (MCCB) to compare the overall cognitive performance of regular smokers (n=40) and nonsmokers (n=36) with schizophrenia. Controlling for age, gender, and education, smokers with schizophrenia were significantly more impaired on a visual learning task, the Brief Visuospatial Memory Test-Revised (BVMT-R), than their nonsmoking peers. Among smokers, smoking behavior (i.e., exhaled carbon monoxide levels of smokers) predicted BVMT-R T score; greater smoking was associated with more impaired visual learning. Negative symptom severity was not predictive of greater visual learning deficits in smokers or nonsmokers. Future longitudinal research will be required to determine if there is a dose-response relationship between chronic nicotine and visual learning impairment in patients at various stages of psychotic illness.

Lung screening is an opportunity for smoking cessation and relapse prevention, but smoking behaviors may differ across screening results. Changes in smoking were evaluated among 18 840 current and former smokers aged 55-74 scheduled to receive three annual lung screenings. Participants were randomized to low-dose computed tomography or single-view chest radiography in the American College of Radiology/National Lung Screening Trial. Outcome measures included point and sustained (6-month) abstinence and motivation to quit among smokers; and relapse among smokers who quit during follow-up, recent quitters (quit < 6 months), and long-term former smokers (quit ≥ 6 months). During five years of follow-up, annual point prevalence quit rates ranged from 11.6%-13.4%; 48% of current smokers reported a quit attempt and 7% of long-term former smokers relapsed. Any false positive screening result was associated with subsequent increased point (multivariable hazard ratio HR = 1.23, 95% CI = 1.13, 1.35) and sustained (HR = 1.28, 95% CI = 1.15, 1.43) abstinence among smokers. Recent quitters with ≥1 false positive screen were less likely to relapse (HR = 0.72, 95% CI = 0.54, 0.96). Screening result was not associated with relapse among long-term former smokers or among baseline smokers who quit during follow-up. A false positive screen was associated with increased smoking cessation and less relapse among recent quitters. Consistently negative screens were not associated with greater relapse among long-term former smokers. Given the Affordable Care Act requires most health plans to cover smoking cessation and lung screening, the impact and cost-effectiveness of lung screening could be further enhanced with the addition of smoking cessation interventions. © The Author 2015.

The World Health Organization recommends that smokers be offered help to quit. A better understanding of smokers' interest in and commitment to quitting could guide tobacco control efforts. We assessed temporal differences in stages of change toward quitting among smokers in Thailand and Turkey. Two waves (independent samples) of data from the Global Adult Tobacco Survey, a national household survey of adults aged 15 years or older, were assessed for Thailand (2009 and 2011) and Turkey (2008 and 2012). Current smokers were categorized into 3 stages of change based on their cessation status: precontemplation, contemplation, and preparation. Relative change in the proportion of smokers in each stage between waves 1 and 2 was computed for each country. Between waves, overall current tobacco smoking did not change in Thailand (23.7% to 24.0%) but declined in Turkey (31.2% to 27.1%; P < .001). Between 2009 and 2011, precontemplation increased among smokers in Thailand (76.1% to 85.4%; P < .001), whereas contemplation (17.6% to 12.0%; P < .001) and preparation (6.3% to 2.6%; P < .001) declined. Between 2008 and 2012, there were declines in precontemplation among smokers in Turkey (72.2% to 64.6%; P < .001), whereas there were increases in contemplation (21.2% to 26.9%; P = .008) and no significant change in preparation (6.5% to 8.5%; P = .097). Nearly two-thirds of smokers in Turkey and more than two-thirds in Thailand were in the precontemplation stage during the last survey wave assessed. The proportion of smokers in the preparation stage increased in Turkey but declined in Thailand. Identifying stages of cessation helps guide population-based targeted interventions to support smokers at varying stages of change toward quitting.

Cigarette smoking and obesity are two major public health problems. However, factors related to the underlying risk for being overweight are not well established. Certain demographic, smoking, and psychological factors have been linked to overweight/obese body mass. The current study examined a multivariate risk model, stratified by gender, in order to better explicate the nature of overweight body mass among daily smokers. In a sample of treatment-seeking smokers (n = 395), among males and females, (1) older age, (2) stronger expectancies about the weight/appetite control effects of smoking, (3) greater smoking-based inflexibility/avoidance due to smoking-related sensations, and (4) less problematic alcohol use, were associated with being overweight. Additionally, among males, having a tobacco-related medical problem and higher tolerance for physical discomfort aided in the discriminant function model for classifying smokers as overweight. Together, numerous cognitive-affective vulnerabilities and smoking processes may be targetable and potentially inform weight-related prevention programs among smokers.

This study examines the impact on smokers' behaviour of a planned increase in the Health and Welfare Surcharge of Tobacco Products in Taiwan. This study used a structured questionnaire to perform telephone interviews. Stratified random sampling was applied to interview current smokers aged 18-65 years in Taiwan. Based on nationwide survey data of smokers' responses to future increases in cigarette prices, this study used multinomial logistic regression to perform its analyses. After the proposed increase in the Health and Welfare Surcharge of Tobacco Products, subsequent cigarette price increases would motivate nearly 30% of the smokers to adopt smoking-related changes and 10% to change to lower-priced brands. The study suggests that a large increase in the Health and Welfare Surcharge of Tobacco Products would lead to considerable changes in smoking behaviour, which in turn would increase cessation rate at the population level.

This study explored cigarette smoking, health status, and interest in quitting among overweight and obese adults with serious mental illness enrolled in a fitness intervention. Baseline data from two studies of the In SHAPE fitness intervention were combined. A total of 341 overweight or obese adults with serious mental illness were assessed on smoking, interest in quitting, cardiovascular fitness, lipids, body mass index, readiness to change diet, and psychiatric symptoms. Thirty-six percent (n=122) of participants were categorized as current smokers. The majority of smokers (84%) were interested in quitting. Smokers were more likely to be younger, male, and less educated than non-smokers. Smokers had lower high-density lipoprotein cholesterol and were less ready to reduce dietary fat, after adjusting for age, gender, and education. Findings highlight the potential to address both fitness and smoking in order to reduce cardiovascular risk in individuals with serious mental illness. PMID:26034872

Current cigarette smoking is associated with reduced acute responses to corticosteroids and worse clinical outcomes in stable chronic asthma. The mechanism by which current smoking promotes this altered behavior is currently unclear. Whilst cytokines can induce corticosteroid insensitivity in-vitro, how current and former smoking affects airway cytokine concentrations and their responses to oral corticosteroids in stable chronic asthma is unclear. To examine blood and sputum cytokine concentrations in never, ex and current smokers with asthma before and after oral corticosteroids. Exploratory study utilizing two weeks of oral dexamethasone (equivalent to 40 mg/day prednisolone) in 22 current, 21 never and 10 ex-smokers with asthma. Induced sputum supernatant and plasma was obtained before and after oral dexamethasone. 25 cytokines were measured by multiplex microbead system (Invitrogen, UK) on a Luminex platform. Smokers with asthma had elevated sputum cytokine interleukin (IL) -6, -7, and -12 concentrations compared to never smokers with asthma. Few sputum cytokine concentrations changed in response to dexamethasone IL-17 and IFNα increased in smokers, CCL4 increased in never smokers and CCL5 and CXCL10 reduced in ex-smokers with asthma. Ex-smokers with asthma appeared to have evidence of an ongoing corticosteroid resistant elevation of cytokines despite smoking cessation. Several plasma cytokines were lower in smokers with asthma compared to never smokers with asthma. Cigarette smoking in asthma is associated with a corticosteroid insensitive increase in multiple airway cytokines. Distinct airway cytokine profiles are present in current smokers and never smokers with asthma and could provide an explanatory mechanism for the altered clinical behavior observed in smokers with asthma.

To further define potential factors that may contribute to stone formation in salivary glands (sialolithiasis), a retrospective chart review was performed of patients diagnosed with sialolithiasis between March 1, 1998 and February 29, 2012. Information on salivary gland stone number, location and size, medical history, medications, and serum electrolyte levels were collected. Associations between electrolyte levels and stone characteristics (such as stone number and size) were examined. Fifty-nine patients were identified; their median age was 58 years (range 25-89 years) and most were male (95%). Salivary stones were most commonly located in the submandibular glands (83%). Thirty-five patients (59%) had a smoking history, with 16 (27%) reported as current smokers. There was a significant association between current smoker status and stone size (mean largest stone size 12.4±8.8mm vs. 7.5±4.8mm in current smokers vs. non-smokers; P=0.03). Serum sodium levels (r=0.32, P=0.014) and serum potassium levels (r=0.31, P=0.017) showed significant positive correlations with stone size. While the aetiology of sialolithiasis remains unclear, smoking (which can contribute to reduced saliva flow) and higher serum sodium levels (which can reflect volume depletion) are associated with larger salivary stones.

There has been resurgence of interest in lung cancer screening using low-dose computed tomography. The implications of directing a screening programme at smokers has been little explored. A nationwide telephone survey was conducted. Demographics, certain clinical characteristics and attitudes about screening for lung cancer were ascertained. Responses of current, former and never smokers were compared. 2001 people from the US were interviewed. Smokers were significantly (p < 0.05) more likely than never smokers to be male, non-white, less educated, and to report poor health status or having had cancer, and less likely to be able to identify a usual source of healthcare. Compared with never smokers, current smokers were less likely to believe that early detection would result in a good chance of survival (p < 0.05). Smokers were less likely to be willing to consider computed tomography screening for lung cancer (71.2% (current smokers) v 87.6% (never smokers) odds ratio (OR) 0.48; 95% confidence interval (CI) 0.32 to 0.71). More never smokers as opposed to current smokers believed that the risk of disease (88% v 56%) and the accuracy of the test (92% v 71%) were important determinants in deciding whether to be screened (p < 0.05). Only half of the current smokers would opt for surgery for a screen-diagnosed cancer. The findings suggest that there may be substantial obstacles to the successful implementation of a mass-screening programme for lung cancer that will target cigarette smokers.

There is a dearth of research focusing on sex work in exotic dance clubs. We conducted a cross-sectional study to examine the prevalence and correlates of crack cocaine smoking among a sample of exotic dancers. The "block," a historical red-light district in downtown Baltimore, MD, is comprised of 30 adult-entertainment establishments. Between 01/09 and 08/09, we conducted a survey with exotic dancers (N=98). The survey explored demographic, and drug and sexual/drug risk behaviors. Bivariate and multivariate analysis was conducted using Poisson regression with robust variance estimates to examine correlates of current crack smoking. Crack cocaine smokers compared to non-crack cocaine smokers were significantly more likely to report: older age (29 vs. 23 years, respectively, p<0.0001); being White (79% vs. 50%, respectively, p=0.008); having been arrested (93% vs. 67%, respectively, p=0.008); daily alcohol consumption (36% vs. 17%, p=0.047); current heroin injection (57% vs. 13%, p<0.001); and current sex exchange (79% vs. 30%, p<0.001). In the presence of other variables, crack cocaine smokers compared to non-crack cocaine smokers were significantly older, more likely to report current heroin injection, and more likely to report current sex exchange. We found high levels of drug use and sexual risk behaviors as well as a number of risks behaviors associated with crack cocaine smoking among this very under-studied population. Targeted interventions are greatly needed. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

There is current controversy about the efficacy of smoking cessation interventions that are based on information obtained by spirometry. The objective of this study is to evaluate the effectiveness in the primary care setting of structured motivational intervention to achieve smoking cessation, compared with usual clinical practice. Multicentre randomized clinical trial with an intervention and a control group. 12 primary care centres in the province of Tarragona (Spain). 600 current smokers aged between 35 and 70 years with a cumulative habit of more than 10 packs of cigarettes per year, attended in primary care for any reason and who did not meet any of the exclusion criteria for the study, randomly assigned to structured intervention or standard clinical attention. Usual advice to quit smoking by a general practitioner as well as a 20-minute personalized visit to provide detailed information about spirometry results, during which FEV1, FVC, FEF 25-75% and PEF measurements were discussed and interpreted in terms of theoretical values. Additional information included the lung age index (defined as the average age of a non-smoker with the same FEV1 as the study participant), comparing this with the chronological age to illustrate the pulmonary deterioration that results from smoking. Spirometry during the initial visit. Structured interview questionnaire administered at the primary care centre at the initial visit and at 12-month follow-up. Telephone follow-up interview at 6 months. At 12-month follow-up, expired CO was measured in patients who claimed to have quit smoking. Smoking cessation at 12 months. Data will be analyzed on the basis of "intention to treat" and the unit of analysis will be the individual smoker. Among active smokers treated in primary care we anticipate significantly higher smoking cessation in the intervention group than in the control group. Application of a motivational intervention based on structured information about spirometry results, improved abstinence rates among smokers seen in actual clinical practice conditions in primary care.

We hypothesized that dietary total fiber intake may be less than recommendations and that the intake of total, soluble, and insoluble fiber may be associated with demographic, lifestyle, and socioeconomic factors. Data were drawn from the Health Survey of São Paulo, a cross-sectional population-based study. Adolescents, adults, and elderly persons living in São Paulo city were included. Demographic, lifestyle, and anthropometric data were collected from households. Dietary intake was measured using two 24-hour dietary recalls. All analyses were conducted based on the sample design of the study. The proportion of individuals who met the adequate intake (AI) for total fiber intake was examined, and foods that contributed to the intake of fiber and fractions were evaluated. The relationship of total, soluble, and insoluble fiber intake with demographic, socioeconomic, and lifestyle characteristics was determined using multiple linear regression models. A low proportion of individuals met the AI for dietary fiber. The foods that most contributed to total fiber intake were beans, French bread, and rice. Total fiber intake was negatively associated with former and current smokers and positively associated with family income per capita and age. Soluble fiber intake was negatively associated with current smokers and positively associated with female sex, age, and family income per capita. Insoluble fiber intake was negatively associated with former or current smokers and positively associated with age. In summary, residents in the city of São Paulo had a low fiber intake, and demographic, socioeconomic, and lifestyle factors were associated with dietary fiber and intake of its fractions.

Asthma is associated with complications, cardiovascular comorbidities, and higher mortality in some individuals. To test the hypothesis that, among individuals with asthma, never-smokers have different characteristics and a better prognosis than smokers. We recruited 94,079 individuals aged 20-100 years from the Copenhagen General Population Study, a prospective cohort study. Among these individuals, 5,691 (6%) had self-reported asthma (2,304 never-smokers, 2,467 former smokers, and 920 current smokers). We examined respiratory symptoms, lung function, and levels of inflammatory and allergic biomarkers in systemic circulation. Furthermore, we assessed prospectively the risk of asthma or chronic obstructive pulmonary disease (COPD) exacerbations, pneumonias, lung cancer, ischemic heart disease, ischemic stroke, and all-cause mortality during 4.5 years of follow-up. Compared with never-smokers without asthma, individuals with asthma had more respiratory symptoms and airflow limitation and higher levels of inflammatory and allergic biomarkers, which were most pronounced in smokers. Among individuals with asthma compared with never-smokers without asthma, multivariable adjusted hazard ratios for asthma exacerbations were 11 (95% confidence interval: 5.8-22) in never-smokers, 13 (6.2-29) in former smokers, and 18 (8.2-39) in current smokers. The corresponding values for other endpoints were, respectively, 8.9 (2.1-38), 23 (8.8-58), and 36 (12-105) for COPD exacerbations; 1.5 (0.9-2.2), 1.6 (1.0-2.4), and 2.4 (1.6-3.7) for pneumonias; 0.6 (0.1-5.1), 4.0 (1.3-12), and 13 (4.3-41) for lung cancer; 1.2 (0.9-1.6), 1.5 (1.2-2.0), and 2.0 (1.4-2.9) for ischemic heart disease; 1.4 (0.9-2.1), 1.2 (0.8-1.9), and 3.0 (1.7-5.3) for ischemic stroke; and 0.9 (0.6-1.3), 1.5 (1.1-2.0), and 2.7 (1.9-3.7) for all-cause mortality. Never-smokers with asthma had an increased risk of asthma and COPD exacerbations, and possibly pneumonias. Importantly, the risks for lung cancer, cardiovascular comorbidities, and death were restricted to smokers with asthma. Thus, tobacco smoking was the main explanation for poor prognosis in asthma.

Despite the fact that smokers have deficit in detecting taste, particularly bitter taste, no study has investigated its biological correlate. In this context, we compared the expression of the bitter taste receptor gene, taste 2 receptor (TAS2R) in the tongues of smokers and non-smokers. Tissue samples were collected from the lateral portion of the tongues of 22 smokers and 22 age- and gender-matched healthy volunteers (19 males and three females) with no history of smoking. Reverse transcriptase-polymerase chain reaction was used to examine the expression of TAS2R in the two groups, and the effect of aging on TAS2R expression was also assessed. TAS2R expression was significantly lower among smokers than non-smokers (t = 6.525, P < .0001, 11.36 ± 6.0 vs. 2.09 ± 2.8, mean ± SD, non-smokers vs. smokers). Further, a positive correlation between age and expression of TAS2R was observed in non-smokers (r = .642, P = .001), but not smokers (r = .124, P = .584). This correlation difference was significant (Z = 1.96, P = .0496). Smokers showed a significantly lower expression of the bitter taste receptor gene than non-smokers, which is potentially caused by their inability to acquire such receptors with age because of cigarette smoking, in contrast to non-smokers.

Objectives: To investigate the association of smoking with bruxism while controlling for genetic and environmental factors using a co-twin-control design. Especially, the role of nicotine dependence was studied in this context. Methods: The material derives from the Finnish Twin Cohort consisting of 12,502 twin individuals who responded to a questionnaire in 1990 (response rate of 77%). All were born in 1930–1957, the mean age being 44 years. The questionnaire covered 103 multiple choice questions, 7 dealing with tobacco use and 22 with sleep and vigilance matters, including perceived bruxism. In addition, a subsample derived from the Nicotine Addiction Genetics Finland Study containing 445 twin individuals was studied. Results: In age- and gender-controlled multinomial logistic regression, both monthly and rarely reported bruxism associated with both current cigarette smoking (odds ratio [OR] = 1.74 and 1.64) and former cigarette smoking (OR = 1.64 and 1.47). Weekly bruxism associated with current smoking (OR = 2.85). Current smokers smoking 20 or more cigarettes a day reported weekly bruxism more likely (OR = 1.61–1.97) than those smoking less. Among twin pairs (N = 142) in which one twin was a weekly bruxer and the cotwin a never bruxer, there were 13 monozygotic pairs in which one twin was a current smoker and the other twin was not. In all cases, the bruxer was the smoker (p = .0003). Nicotine dependence associated significantly with bruxism. Conclusions: Our twin study provides novel evidence for a possible causal link between tobacco use and bruxism among middle-aged adults. Nicotine dependence may be a significant predisposing factor for bruxism. PMID:21041838
Tobacco Use Among Students Aged 13-15 Years in South Korea: The 2013 Global Youth Tobacco Survey

Objectives We examined the prevalence of tobacco use and exposure to secondhand smoke among middle-school students in Korea using the Global Youth Tobacco Survey (GYTS) in 2013. Methods The GYTS in Korea was conducted between July and August 2013 by the Korea Centers for Disease Control and Prevention. Data were collected using a self-administered anonymous questionnaire from a nationally representative sample of middle-school students aged 13-15 years in sampled classrooms. Results The GYTS in Korea was completed by 4235 students aged 13-15 years in 43 middle schools. Approximately one in five of the students (17.8%) reported that they had tried cigarettes in the past, while 5.2% reported currently being cigarette smokers. Current cigarette smoking was higher in boys (7.5%) than in girls (2.6%). Of the students, 29.7% had been exposed to secondhand smoke at home, 47.4% inside enclosed public places, and 53.9% in outdoor public places. Of the current cigarette smokers, 25.7% bought their cigarettes from a store despite a law prohibiting this. Additionally, 58.0% of students noticed point-of-sale tobacco advertisements or promotions, 66.8% of current cigarette smokers wanted to stop smoking, and 70.9% of students had been taught about the dangers of tobacco use in school. Conclusions These findings provide an opportunity to develop, implement, and evaluate a comprehensive tobacco control policy. The results suggest that youth have relatively easy access to cigarettes and are regularly exposed to secondhand smoke in public places, as well as to point-of-sale tobacco advertisements and promotions. Strict enforcement of the ban on tobacco sales to youth, expanding smoke-free areas, and advertising bans are needed to reduce tobacco use among youth. PMID:28173685

The US Surgeon General has concluded that e-cigarette aerosol is not harmless and can contain harmful and potentially harmful chemicals, including nicotine. We assessed factors associated with adults' perceptions of harm related to children's exposure to secondhand aerosol from electronic vapor products (EVPs). Data came from the 2015 Styles, an Internet panel survey of US adults aged 18 years or older (n = 4,127). Respondents were asked whether they believe aerosol from other people's EVPs causes children harm. Harm perceptions were assessed overall and by cigarette smoking, EVP use, and sociodemographic characteristics. Multinomial logistic regression was used to assess odds of perceived harm. Overall, 5.3% of adults responded that secondhand EVP exposure caused "no harm" to children, 39.9% responded "little harm" or "some harm," 21.5% responded "a lot of harm," and 33.3% responded "don't know." Odds of "no harm" response were greater among men than among women, current and former cigarette smokers than among never smokers, and current and former EVP users than among never users; odds were lower among non-Hispanic blacks, Hispanics, and non-Hispanic other races than among non-Hispanic whites. Odds of responding "don't know" were greater among men, current cigarette smokers, and current and former EVP users; odds were lower among those aged 45 to 64 years than those aged 18 to 24 years and lower among non-Hispanic other races and Hispanics than non-Hispanic whites. Two-fifths of US adults believe that children's exposure to secondhand EVP aerosol causes some or little harm, while one-third do not know whether it causes harm. Efforts are warranted to educate the public about the health risks of secondhand EVP aerosol, particularly for children.

To determine the relationship between BMI and risk of CVD mortality and all-cause mortality among Malaysian adults. Population-based, retrospective cohort study. Participants were followed up for 5 years from 2006 to 2010. Mortality data were obtained via record linkages with the Malaysian National Registration Department. Multiple Cox regression was applied to compare risk of CVD and all-cause mortality between BMI categories adjusting for age, gender and ethnicity. Models were generated for all participants, all participants the first 2 years of follow-up, healthy participants, healthy never smokers, never smokers, current smokers and former smokers. All fourteen states in Malaysia. Malaysian adults (n 32 839) aged 18 years or above from the third National Health and Morbidity Survey. Total follow-up time was 153 814 person-years with 1035 deaths from all causes and 225 deaths from CVD. Underweight (BMI<18·5 kg/m2) was associated with a significantly increased risk of all-cause mortality, while obesity (BMI ≥30·0 kg/m2) was associated with a heightened risk of CVD mortality. Overweight (BMI=25·0-29·9 kg/m2) was inversely associated with risk of all-cause mortality. Underweight was significantly associated with all-cause mortality in all models except for current smokers. Overweight was inversely associated with all-cause mortality in all participants. Although a positive trend was observed between BMI and CVD mortality in all participants, a significant association was observed only for severe obesity (BMI≥35·0 kg/m2). Underweight was associated with increased risk of all-cause mortality and obesity with increased risk of CVD mortality. Therefore, maintaining a normal BMI through leading an active lifestyle and healthy dietary habits should continue to be promoted.

Current guidelines advise providers to assess smokers' readiness to quit, then offer cessation therapies to smokers planning to quit and motivational interventions to smokers not planning to quit. We examined the relationship between baseline stage of change (SOC), treatment utilization, and smoking cessation to determine whether the effect of a proactive smoking cessation intervention was dependent on smokers' level of motivation to quit. Secondary analysis of a multicenter randomized controlled trial. A total of 3006 current smokers, aged 18-80 years, at four Veterans Affairs (VA) medical centers. Proactive care included proactive outreach (mailed invitation followed by telephone outreach), offer of smoking cessation services (telephone or face-to-face), and access to pharmacotherapy. Usual care participants had access to VA smoking cessation services and state telephone quitlines. Baseline SOC measured with Readiness to Quit Ladder, and 6-month prolonged abstinence self-reported at 1 year. At baseline, 35.8 % of smokers were in preparation, 38.2 % in contemplation, and 26.0 % in precontemplation. The overall interaction between SOC and treatment arm was not statistically significant (p = 0.30). Among smokers in preparation, 21.1 % of proactive care participants achieved 6-month prolonged abstinence, compared to 13.1 % of usual care participants (OR, 1.8 [95 % CI, 1.2-2.6]). Similarly, proactive care increased abstinence among smokers in contemplation (11.0 % vs. 6.5 %; OR, 1.8 [95 % CI, 1.1-2.8]). Smokers in precontemplation quit smoking at similar rates (5.3 % vs. 5.6 %; OR, 0.9 [95 % CI, 0.5-1.9]). Within each stage, uptake of smoking cessation treatments increased with higher SOC and with proactive care as compared with usual care. Mostly male participants limits generalizability. Randomization was not stratified by SOC. Proactive care increased treatment uptake compared to usual care across all SOC. Proactive care increased smoking cessation among smokers in preparation and contemplation but not in precontemplation. Proactively offering cessation therapies to smokers at all SOC will increase treatment utilization and population-level smoking cessation.

Cigarettes with candy, fruit and alcohol flavors have been introduced in recent years as extensions to popular cigarette brands, raising concerns in the public health community that the enticing names, creative packaging, and intense flavorings of these products may be especially appealing to youth. This study used two national surveys to examine the prevalence of use of Camel Exotic Blends, Kool Smooth Fusion, and Salem Silver Label brands during 2004--2005 among older adolescents and young adult smokers aged 17-26 years and adult smokers aged > or =25 years. Overall use of any of these flavored brands in the past 30 days was 11.9% among smokers aged 17-26 years and 6.7% among smokers aged > or =25 years. A significant gradient in use was seen across age, with the highest rates of utilization among 17-year-old (22.8%) and 18-19-year-old smokers (21.7%) (p<.001). Uniquely flavored cigarette brands seem to be most attractive to the youngest smokers and should be prohibited.

Smoking gives rise to many cross-sectorial public costs and benefits for government. Costs arise from increased healthcare spending and work-related social benefits, while smoking itself provides significant revenue for government from tobacco taxes. To better understand the public economic impact of smoking and smoking cessation therapies, this study developed a government perspective framework for assessing smoking-attributable morbidity and mortality and associated public costs. This framework includes changes in lifetime tax revenue and health costs, as well as changes in tobacco tax revenue, from fewer smokers. A modified generational accounting framework was developed to assess relationships between smoking-attributable morbidity and mortality and public economic consequences of smoking, including lifetime tax revenue gains/losses, government social transfers, and health spending. Based on the current prevalence of smoking in South Korean males, a cohort model was developed for smokers, former-smokers, and never-smokers. The model simulated the lifetime discounted fiscal transfers for different age cohorts in 5 year age bands, and the return on investment (ROI) from smoking cessation therapy. Former smokers are estimated to generate higher lifetime earnings and direct tax revenues and lower lifetime healthcare costs due to the reduction of smoking-attributable mortality and morbidity compared to smokers, even after accounting for reduced tobacco taxes paid. Based on the costs of public investments in varenicline, this study estimated a ROI from 1.4-1.7, depending on treatment age, with higher ROI in younger cohorts, with an average ROI of 1.6 for those aged less than 65. This analysis suggests that reductions in smoking can generate positive public economic benefits for government, even after accounting for lost tobacco tax revenues. The results described here are likely applicable to countries having similar underlying smoking prevalence, comparable taxation rates, and social benefit protection provided to individuals with smoking-related conditions.

Recent neuroimaging research suggests sex-related brain differences in smoking addiction. In the present pilot study, we assessed gender-related differences in brain activation in response to cigarette-related video cues, investigating non-smokers, smokers, and ex-smokers. First, we compared 29 females (28.6 ± 5.3) vs. 23 males (31.5 ± 6.4), regardless of current smoking status to assess global gender-related effects. Second, we performed a post hoc analysis of non-smokers (9 females and 8 males), smokers (10 females and 8 males), and ex-smokers (10 females and 7 males). Participants performed a block-design functional magnetic resonance imaging paradigm contrasting smoking with control cue video exposures. Data analyses included task-related general linear model, voxel-based morphometry of gray matter (GM), and tract-based spatial statistics of white matter (WM). First, the global effect regardless of current smoking status revealed higher activation in the bilateral superior frontal gyrus and anterior cingulate cortex (ACC) for females compared to males. Second, the analysis according to current smoking status demonstrated higher activation in female vs. male smokers vs. non-smokers in the superior frontal gyrus, anterior and posterior cingulate cortex, and precuneus, and higher activation in female vs. male ex-smokers vs. non-smokers in the right precentral gyrus, in the right insula and ACC. No structural differences were found in GM or WM. The current study identifies gender-related brain functional differences in smokers and ex-smokers compared to non-smokers. The current work can be considered as a starting point for future investigations into gender differences in brain responses to cigarette-related cues.

Rationale There is little information about long-term relapse patterns for cigarette smokers. Objective To describe long-term prevalence of relapse and related smoking patterns by sex, race, age, and education level among a community-based cohort of young adults followed for 25 years. Methods We examined 25 years of data from Coronary Artery Risk Development in Young Adults (CARDIA), an ongoing study of a community-based cohort of 5115 men and women aged 18 to 30 years at baseline with periodic re-examinations. At each examination smoking, quitting, and relapse were queried. We examined prevalence of smoking relapse among 3603 participants who attended at least 6 of the 8 examinations. Results About 53% of 3603 participants never reported smoking on a regular basis. Among the remaining 1682 ever smokers, 52.8% of those who reported current smoking at baseline were still smoking by the end of the study, compared to 10.7% of those who initiated smoking by year 5. Among those classified as former smokers at baseline, 39% relapsed at least once; of these, 69.5% had quit again by the end of the study. Maximum education level attained, age at study baseline, and race were associated with failure to quit smoking by the end of the study and relapse among those who did quit. Maximum education level attained and age at study baseline were also associated with ability to successfully quit after a relapse. Conclusions Smoking relapse after quitting is common, especially in those with lower education level. Education was the strongest predictor of all three outcomes. Improvements in access to treatment and treatment options, especially for underserved populations, are needed to prevent relapse when smokers quit. PMID:24172753

Sweden has shown a decreasing tendency in the incidence of myocardial infarction (MI), except among middle-aged women. The incidence among middle-aged immigrant women is less explored. To determine if foreign-born women have a higher risk of MI as compared to women born in Sweden. Furthermore, to examine if physical activity (PA) modifies the risk of MI regardless of immigration status and smoking habits. The Malmö Diet and Cancer Study was used for analyses. A total of 16,776 women aged 45-73 years participated. The mean follow-up time was 13.8±4 years. Mean age was 57.4±7.9 years. No difference was found in incidence of MI between Swedish and immigrant women (p=0.72). For current smokers among Swedish women, the relative risk (RR) with no/low PA was 2.93 (95% CI 2.07-4.14) and with moderate/high PA, the RR was 2.21 (95% CI 1.61-3.03) with no/low PA-never smoker as the reference group. Among immigrant smoking women, the RR with no/low PA was 4.56 (95% CI 1.62-12.8) and with moderate/high PA, the RR was 3.27 (95% CI 1.21-8.84) with no/low PA-never smoker as the reference group. PA reduces the risk of MI in non-smokers as well as in smokers, regardless of immigration status. Furthermore, PA was even more beneficial for women born outside Sweden. Against this background, immigrant women ought to get special consideration and attention from both caregivers and public health workers.

Objective: To examine the prevalence and correlates of internet cigarette purchasing among adult smokers. Design: Analysis of internet purchasing in data from a population based telephone survey of New Jersey households. Logistic regression was used to determine factors associated with internet cigarette purchasing, adjusting for year, demographic, and smoking behaviour variables. Participants: 3447 current cigarette smokers pooled from three cross sectional surveys conducted in 2000, 2001, and 2002. Main outcome measures: Ever purchasing tobacco and usually buying cigarettes via the internet. Results: Among all current cigarette smokers, ever having purchased tobacco via the internet increased from 1.1% in 2000 to 6.7% in 2002 and usually buying cigarettes via the internet increased from 0.8% in 2000 to 3.1% in 2002. Among current cigarette smokers with internet access, ever having purchased tobacco via the internet was higher among those who reported smoking 31 or more cigarettes per day (adjusted odds ratio (OR) 3.9, 95% confidence interval (CI) 1.5 to 10.2) and those without a past year quit attempt (adjusted OR 1.8, 95% CI 1.1 to 3.0). Usually purchasing cigarettes via the internet was higher among those aged 45–64 years (adjusted OR 4.4, 95% CI 1.1 to 17.1) and who reported having their first cigarette ⩽ 30 minutes after waking (adjusted OR 3.3, 95% CI 1.2 to 9.2). Conclusions: Although higher prices are known to reduce the demand for cigarettes, internet cigarette purchasing is likely to weaken this effect, particularly among heavy, more dependent smokers who are less interested in quitting.

Electronic cigarettes (e-cigarettes) are increasingly used in adolescents with unknown impacts on conventional cigarette smoking. We examined the associations of e-cigarette use with smoking intention, nicotine addiction and smoking cessation in Chinese adolescents. A total of 45,128 students (age 14.6 ± 1.9; boys 51.4%) from 75 randomly selected schools in Hong Kong reported e-cigarette use (in the past 30 days), conventional cigarette use and socio-demographic characteristics in an anonymous questionnaire survey. Adjusted odds ratios (AORs) of intention to smoke, morning smoking urge, intention to quit and quit attempts; and beta-coefficient (β) of cigarette consumption per day were calculated in relation to e-cigarette use. E-cigarette use was associated with intention to smoke with an AOR (95% CI) of 1.74 (1.30-2.31) in all students, 2.18 (1.12-4.23) in never and 2.79 (2.05-3.79) in ever smokers (non-significant interaction by smoking status). The associations were also significant in experimental and former smokers but not in current smokers. In current smokers, e-cigarette use was significantly associated with heavier smoking (β 2.54, 95% CI 1.28-3.81) and morning smoking urge (AOR 2.54, 95% CI 1.50-3.11), and non-significantly associated with lower quit intention (0.76, 0.52-1.09) and attempts (0.80, 0.56-1.23). E-cigarette use was associated with smoking intention in never, experimental and former smokers in Hong Kong Chinese adolescents. In current smokers, e-cigarette use was associated with nicotine addiction but not quit intention and attempts. Prospective studies with detailed measurements on e-cigarette use are warranted for further studies. Copyright © 2015 Elsevier Ltd. All rights reserved.

Research indicates disparities in risky health behaviors between heterosexual and sexual minority (referred to as LGBQ; also known as lesbian, gay, bisexual, queer, and questioning) youth. Limited data are available for tobacco-use-related behaviors beyond smoking status. We compared data on tobacco age of initiation, product use, and secondhand smoke exposure between general population and LGBQ youth. Data for general population youth were from the statewide, representative 2011 Missouri Youth Tobacco Survey, and data for LGBQ youth were from the 2012 Out, Proud and Healthy survey (collected at Missouri Pride Festivals). Age-adjusted Cochran-Mantel-Haenszel tests were used to examine differences between general population (N = 1,547) and LGBQ (N = 410) youth, aged 14 to 18 years. Logistic regression models identified variables associated with current smoking. The 2 groups differed significantly on many tobacco-use-related factors. General population youth initiated smoking at a younger age, and LGBQ youth did not catch up in smoking initiation until age 15 or 16. LGBQ youth (41.0%) soon surpassed general population youth (11.2%) in initiation and proportion of current smokers. LGBQ youth were more likely to use cigars/cigarillos, be poly-tobacco users, and be exposed to secondhand smoke (SHS) in a vehicle (for never smokers). Older age (odds ratio [OR] = 1.39, 95% confidence interval [95% CI] = 1.18-1.62), female sex (OR = 1.64, 95% CI = 1.13-2.37), LGBQ identity (OR = 3.86, 95% CI = 2.50-5.94), other tobacco product use (OR = 8.67, 95% CI = 6.01-12.51), and SHS exposure in a vehicle (OR = 5.97, 95% CI = 3.83-9.31) all significantly increased the odds of being a current smoker. This study highlights a need for the collection of data on sexual orientation on youth tobacco surveys to address health disparities among LGBQ youth.

The limited representativeness of trial samples may restrict external validity. The aim of this study was to ascertain the representativeness of the population enrolled in the Cessation in Pregnancy Incentives Trial (CPIT), a therapeutic exploratory study to examine the effectiveness of financial incentives for smoking cessation during pregnancy. CPIT participants (n = 492) were compared with all self-reported smokers at maternity booking who did not participate in the trial (n = 1982). Both groups were drawn from the National Health Service (NHS) Greater Glasgow and Clyde area over a 1-year trial enrolment period. Variables used for comparison were age, area-based deprivation index, body mass index, gestation, and carbon monoxide (CO) breath test level. Chi-square and Mann-Whitney U tests were used to compare groups. From January to December 2012, 2474/13,945 (17.7 %) women, who booked for maternity care, self-reported as current smokers (at least one cigarette in the last week). Seven hundred and fifty-two were ineligible for trial participation because of a CO breath test level of less than 7 parts per million (ppm) used as a biochemical cut-off to corroborate self-report of current smoking. At telephone consent 301 could not be contacted, 11 had miscarried, 16 did not give consent and 3 opted out after randomisation, leaving 492 participants for analysis. There were no differences in demographic or clinical characteristics between trial participants, and self-reported smokers not enrolled in the trial in terms of CO breath test (as a measure of smoking level for those with a CO level of 7 ppm or higher), material deprivation (using an area-based measure), maternal age and maternal body mass index. Gestation at booking was statistically significantly lower for participants. To ensure that all trial participants were smokers, biochemical validation excluded self-reported smokers with a CO level of less than 7 ppm from taking part in the trial, which excluded 30 % of self-reported smokers who were 'lighter' smokers. The efficacy of financial incentives would not have been likely to decrease if 'lighter' smokers had been included in the trial population. Trial participants were slightly earlier in their pregnancy at maternity booking, but this difference would not clinically affect the provision of financial incentives if provided routinely. Overall, the trial population was representative of all self-reported smokers with regard to available routinely collected data. Appropriate comparison of trial and target populations, with detailed reporting of exclusion criteria would contribute to the understanding of the wider applicability of trial results.

In chronic smokers there is evidence for increased formation of oxygen-derived free radicals within the vessel wall impairing endothelial function. It has been suggested that the inactivation of endothelium-derived nitric oxide by oxygen free radicals contributes to endothelial dysfunction. Hence, we tested the hypothesis that in chronic smokers the antioxidant ascorbic acid could improve abnormal endothelial function of epicardial coronary arteries. Thirty-one patients (mean age 57 +/- 9 years) referred for routine diagnostic catheterization for evaluation of chest pain and without angiographically significant coronary artery stenoses were randomly assigned to one of the study groups to assess vasomotor response of epicardial coronary arteries due to cold pressor testing (CPT) before and after intravenous infusion of 3 g of ascorbic acid or 100 ml x 0.9% saline infusion. In 6 controls (mean age 55 +/- 3 years) CPT led to a similar increase in luminal area before and after ascorbic acid administration (26.5 +/- 15.0 vs. 28.4 +/- 17.7%, p = NS). In 15 chronic smokers (mean age 55 +/- 9 years), CPT induced a decrease in the luminal area of -18.5 +/- 6.3%. This flow-dependent vasoconstriction was significantly reversed to 7.7 +/- 6.2% (p < or = 0.03) vasodilation after intravenous ascorbic acid administration. In 10 chronic smokers (mean age 57 +/- 11 years) saline infusion (placebo) did not have a significant effect on CPT-induced vasoconstriction (-12.7 +/- 5.1 vs. -13.1 +/- 5.1%, p = NS). The CPT-induced increase in luminal area in chronic smokers after ascorbic acid infusion was significant compared to controls and placebo (each p < or = 0.05). Our assessment of endothelium-independent responses to nitroglycerin revealed no significant differences between the single study groups (p = NS). In chronic smokers acute intravenous administration of ascorbic acid significantly improves CPT-induced coronary endothelium-dependent dysfunction. According to the current understanding, this effect is due to improved cellular redox imbalance and prevention of nitric oxide inactivation in the endothelium and subendothelial space.

In August 2015, the Food and Drug Administration (FDA) issued warning letters to cigarette manufacturers promoting brands as "natural" or "additive-free" because of concerns that such marketing claims might mislead consumers into believing that these brands are less dangerous to smoke than others. The current study examined consumer beliefs about the relative harms of "natural" cigarettes, and whether these beliefs influenced perceptions of advertising and purchase intentions when participants were shown an advertisement for American Spirit cigarettes. Data were collected using a web-based survey conducted in 2013 among 3,006 U.S.-based web panel members aged 15 to 65 years. Ratings of "natural" cigarette health risks (i.e., misperceptions) differed by sex, race, education, smoking status, and age. Controlling for perceived risks of other cigarette types, never smokers ( B = -0.31, p < .001) and ever/former smokers ( B = -0.15, p = .002) had significantly fewer misperceptions of "natural" cigarettes than current smokers. Current smoking (odds ratio [OR] = 17.8), believing the ad was truthful (OR = 1.18), and having more misperceptions about "natural" cigarette health risks (OR = 1.13) were independently associated with greater purchase intention. Consumers perceived cigarettes marketed as "natural" or "additive-free" as less harmful, and this influenced their perceptions of advertising claims and intention to purchase, controlling for other factors. These findings underscore Food and Drug Administration's recent warning letters.

Recent studies have shown an association between cigarettes per day (CPD) and a nonsynonymous single-nucleotide polymorphism in CHRNA5, rs16969968. To determine whether the association between rs16969968 and smoking is modified by age at onset of regular smoking. Primary data. Available genetic studies containing measures of CPD and the genotype of rs16969968 or its proxy. Uniform statistical analysis scripts were run locally. Starting with 94,050 ever-smokers from 43 studies, we extracted the heavy smokers (CPD >20) and light smokers (CPD ≤10) with age-at-onset information, reducing the sample size to 33,348. Each study was stratified into early-onset smokers (age at onset ≤16 years) and late-onset smokers (age at onset >16 years), and a logistic regression of heavy vs light smoking with the rs16969968 genotype was computed for each stratum. Meta-analysis was performed within each age-at-onset stratum. Individuals with 1 risk allele at rs16969968 who were early-onset smokers were significantly more likely to be heavy smokers in adulthood (odds ratio [OR] = 1.45; 95% CI, 1.36-1.55; n = 13,843) than were carriers of the risk allele who were late-onset smokers (OR = 1.27; 95% CI, 1.21-1.33, n = 19,505) (P = .01). These results highlight an increased genetic vulnerability to smoking in early-onset smokers.

Rationale Chronic obstructive pulmonary disease (COPD) is often associated with age-related systemic abnormalities that adversely affect the prognosis. Whether these manifestations are linked to the lung alterations or are independent complications of smoking remains unclear. Objectives To look for aging-related systemic manifestations and telomere shortening in COPD patients and smokers with minor lung destruction responsible for a decline in the diffusing capacity for carbon monoxide (DLCO) corrected for alveolar volume (KCO). Methods Cross-sectional study in 301 individuals (100 with COPD, 100 smokers without COPD, and 101 nonsmokers without COPD). Measurements and Main Results Compared to control smokers, patients with COPD had higher aortic pulse-wave velocity (PWV), lower bone mineral density (BMD) and appendicular skeletal muscle mass index (ASMMI), and shorter telomere length (TL). Insulin resistance (HOMA-IR) and glomerular filtration rate (GFR) were similar between control smokers and COPD patients. Smokers did not differ from nonsmokers for any of these parameters. However, smokers with normal spirometry but low KCO had lower ASMMI values compared to those with normal KCO. Moreover, female smokers with low KCO, had lower BMD and shorter TL compared to those with normal KCO. Conclusions Aging-related abnormalities in patients with COPD are also found in smokers with minor lung dysfunction manifesting as a KCO decrease. Decreased KCO might be useful, particularly among women, for identifying smokers at high risk for aging-related systemic manifestations and telomere shortening. PMID:25785739

One thousand school boys aged 8 to 16 were examined for their somatotype, physical growth, sexual maturation, and smoking habits. Fifty-two boys were found to be smokers, of whom 30 were regularly smoking between two and 20 bidis or cigarettes a day for a mean duration of 2.5 years. The mean height and weight of the smokers was significantly lower than that of the non-smokers at all ages, more so in regular than occasional smokers. Sixty-nine per cent of the smokers had mesomorphic type of body build; about 65% of the non-smokers had ectomorphic somatotype (P less than 0.001). Onset of puberty occurred significantly earlier among smokers compared with non-smokers, as was evident from the early appearance of genital stage 2, and an early and rapid increase in testicular size. Genital stage 2 appeared at a mean age of 11 years in smokers and 11.6 years in non-smokers. However, the appearance of pubic, axillary, and facial hair was delayed. The possible significance of this is discussed. PMID:7241030

Smoking is associated with high incidence of cardiovascular events including acute coronary syndrome. We sought to characterize coronary plaques in patients with ongoing smoking using optical coherence tomography (OCT) compared with former smokers and nonsmokers. We identified 465 coronary plaques from 182 subjects who underwent OCT imaging for all 3 coronary arteries. Subjects were divided into 3 groups: current smokers (n = 41), former smokers (n = 67), and nonsmokers (n = 74). OCT analysis included the presence of lipid-rich plaque, thin-cap fibroatheroma (TCFA), calcification, maximum lipid arc, lipid core length, lipid index, and fibrous cap thickness. Lipid index was defined by mean lipid arc multiplied by lipid core length. Compared with former smokers and nonsmokers, the incidence of lipid plaques and TCFA was significantly higher in current smokers (lipid plaques: 68.0% vs 45.9% and 52.6%, p = 0.002; TCFA: 18.4% vs 7.6% and 9.9%, p = 0.018). There was a trend for higher plaque disruption in current smokers. Former smokers were more likely to have calcified plaques than current and nonsmokers (52.9% vs 32.0% and 38.0%, p = 0.001). In a multivariate analysis, current smoking, low-density lipoprotein, and presentation with acute coronary syndrome were independently associated with the presence of TCFAs. In conclusion, current smokers are more likely to have lipid plaques and OCT-defined vulnerable plaques (TCFAs). Former smokers have increased number of calcified plaques. These results may explain the increased risk of acute cardiac events among smokers. Copyright © 2014 Elsevier Inc. All rights reserved.

The present investigation examined intrinsic and extrinsic reasons for quitting among daily cigarette smokers with posttraumatic stress disorder (PTSD) as compared to clinical daily smokers with other anxiety and mood disorders (AM) and daily smokers with no current Axis I psychopathology (C) prior to a self-guided quit attempt. It was hypothesized that (1) the PTSD group would report greater intrinsic (ie, self-control and health concerns) reasons for quitting smoking, and (2) among those with PTSD, anxiety sensitivity (fear of anxiety; AS) would predict greater intrinsic reasons for quitting smoking. Participants were 143 (58.7% female; M(age) = 29.66 years, SD = 11.88) daily cigarette smokers. Partially consistent with prediction, the PTSD group reported significantly greater self-control intrinsic reasons for quitting, but not health concern intrinsic reasons, than the C group (p < .01). The PTSD group also reported greater immediate reinforcement extrinsic reasons for quitting than the C group (p < .05). The PTSD and AM groups did not significantly differ on any reasons for quitting. Also partially consistent with hypotheses, higher levels of anxiety sensitivity in daily smokers with Axis I psychopathology (both PTSD and AM groups) significantly predicted greater self-control intrinsic reasons for quitting. AS did not significantly predict immediate reinforcement extrinsic reasons for quitting. The current findings suggest that individuals with PTSD and other psychopathology may have unique motivations for quitting smoking that could be usefully explored within smoking cessation treatment programs.

The aim of the current study is to examine the association of environmental tobacco smoke (ETS) exposure evident by serum cotinine level, and diabetes mellitus in never smokers. Previous studies suggest that active tobacco cigarette smoking is associated with diabetes mellitus risk. However it is not clear if the low-level "background" ETS exposure is associated with diabetes among never smokers. We present evidence from five independent replications based on the US nationally representative National Health and Nutrition Examination Surveys (NHANES) conducted 2003-12. Our exposure of interest is ETS exposure among never smokers, measured by serum cotinine levels (ng/mL), and our main outcome is diabetes mellitus assessed via self-reported physician-diagnosis, current use of insulin and/or oral hypoglycemic medications, plasma fasting glucose levels ≥126mg/dL or glycohemoglobin levels ≥6.5%. The conceptual model encompassed age, sex, ethnic self-identification, education, poverty-income ratio, alcohol drinking, total cholesterol and body mass index. In never smokers, higher serum cotinine levels were positively associated with diabetes mellitus (the meta-analytic summary estimate is 1.2, 95% CI=1.1, 1.2). This association was not evident among never smokers with cotinine levels below 3ng/mL. These replications help sustain evidence of ETS-diabetes mellitus association, which might be explained by shared psychosocial characteristics. Prospective studies with appropriate biomarkers are needed to further investigate this association. Copyright © 2015 Elsevier Inc. All rights reserved.

Concurrent use of cigarettes with alternative tobacco products (ATPs), even among very light smokers, may be harmful. This study examined current use of e-cigarettes, cigars, and hookah, and susceptibility to future use of these products in a sample of college student cigarette smokers. Participants were 1161 18-29 year old (M age = 21.15; SD = 2.72; 52.7% female; 41.2% non-Hispanic white) current, or past 30-day cigarette smokers, drawn from a larger study. Current smokers were categorized as very light smokers [≤5 cigarettes per day (cpd)] and heavier smokers (>5 cpd). 88.6% of all participating college student smokers were very light smokers and 67.7% used at least one ATP concurrently. The prevalence of current use in this sample was 42.9% for e-cigarettes, 36.4% for hookah, and 25.9% for cigars. Compared to heavier smokers, very light smokers were more likely to be younger, racial/ethnic minorities, and four-year versus two-year college students. Multilevel logistic regression models showed that after controlling for socio-demographic characteristics and substance use, being a very light smoker, compared with a heavier smoker, was negatively associated with concurrent e-cigarette use, but positively associated with concurrent cigar use, and not associated with concurrent hookah use. Moreover, compared to heavier smokers, very light smokers reported being more susceptible to future cigar and hookah use, but not e-cigarette use. Concurrent use of cigarettes with ATPs is popular among all college student smokers, but very light smokers are more likely than heavier smokers to use combustible ATPs. Smoking intervention programs and campus policies should caution smokers, especially very light smokers, against ATP use. Copyright © 2018 Elsevier Ltd. All rights reserved.

Given plans to extend its regulatory authority to e-cigarettes, the Food and Drug Administration (FDA) urgently needs to understand how e-cigarettes are perceived by the public. To examine how smoking status impacts adult perceptions and expectations of e-cigarettes. We used Mechanical Turk (MTurk), a "crowdsourcing" platform, to rapidly survey a large (n = 796; female = 381; male = 415), diverse sample of adult ever (44%) and never smokers (56%), including ever (28%) and never (72%) users of e-cigarettes. Smokers and non-smokers learned about e-cigarettes primarily through the internet and conversations with others. Ever smokers were more likely than never smokers, and female current smokers were more likely than female former smokers, to have learned about e-cigarettes from point of sale advertising (p's < 0.05) and to believe that e-cigarettes help smokers quit (ps < 0.05). Among never users of e-cigarettes, current smokers were more likely than never smokers and former smokers to report that they would try e-cigarettes in the future (ps < 0.01). Current smokers' top reason for wanting to try e-cigarettes was to quit or reduce smoking (56%), while never and former smokers listed curiosity. In contrast, female current smokers' top reason for not trying e-cigarettes was health and safety concerns (44%) while males were deterred by expense (44%). Adult smokers and non-smokers have different perceptions and expectations of e-cigarettes. Public health messages regarding e-cigarettes may need to be tailored separately for persons with and without a history of using conventional cigarettes. Tailoring messages by gender within smoker groups may also improve their impact.
Reinforcing effects of cigarette advertising on under-age smoking.
Aitken, P P; Eadie, D R
1990-03-01
Interviews were conducted with 848 Glasgow children aged between 11 and 14 years. There were consistent differences between smokers and non-smokers. Smokers tended to be more adept at recalling, recognizing and identifying cigarette advertisements. This suggests they tend to pay more attention to cigarette advertising. Smokers also tended to be generally more appreciative of cigarette advertising. Moreover, this greater awareness and appreciation of cigarette advertising was independent of other important predictors of under-age smoking, such as smoking by peers, siblings and parents. These findings, taken in conjunction with previous research, indicate that cigarette advertising is reinforcing under-age smoking. The smokers showed an enhanced or heightened preference for Kensitas Club, the brand favoured by adults. This is consistent with previous research indicating that promotional devices which help determine and reinforce adult cigarette brand preferences have an even greater effect on under-age smokers.
Health Care Utilization and Expenditures Attributable to Cigar Smoking Among US Adults, 2000-2015.
Wang, Yingning; Sung, Hai-Yen; Yao, Tingting; Lightwood, James; Max, Wendy
Cigar use in the United States is a growing public health concern because of its increasing popularity. We estimated health care utilization and expenditures attributable to cigar smoking among US adults aged ≥35. We analyzed data on 84 178 adults using the 2000, 2005, 2010, and 2015 National Health Interview Surveys. We estimated zero-inflated Poisson (ZIP) regression models on hospital nights, emergency department (ED) visits, physician visits, and home-care visits as a function of tobacco use status-current sole cigar smokers (ie, smoke cigars only), current poly cigar smokers (smoke cigars and smoke cigarettes or use smokeless tobacco), former sole cigar smokers (used to smoke cigars only), former poly cigar smokers (used to smoke cigars and smoke cigarettes or use smokeless tobacco), other tobacco users (ever smoked cigarettes and used smokeless tobacco but not cigars), and never tobacco users (never smoked cigars, smoked cigarettes, or used smokeless tobacco)-and other covariates. We calculated health care utilization attributable to current and former sole cigar smoking based on the estimated ZIP models, and then we calculated total health care expenditures attributable to cigar smoking. Current and former sole cigar smoking was associated with excess annual utilization of 72 137 hospital nights, 32 748 ED visits, and 420 118 home-care visits. Annual health care expenditures attributable to sole cigar smoking were $284 million ($625 per sole cigar smoker), and total annual health care expenditures attributable to sole and poly cigar smoking were $1.75 billion. Comprehensive tobacco control policies and interventions are needed to reduce cigar smoking and the associated health care burden.

Cigarette smoking has been linked with several factors associated with cardiac dysfunction. We hypothesized that cigarette smoking is associated with left ventricular (LV) structure and function, and incident heart failure (HF) hospitalization. We investigated 4129 (never smoker n=2884, current smoker n=503, and former smoker n=742) black participants (mean age, 54 years; 63% women) without a history of HF or coronary heart disease at baseline in the Jackson Heart Study. We examined the relationships between cigarette smoking and LV structure and function by using cardiac magnetic resonance imaging among 1092 participants, cigarette smoking and brain natriuretic peptide levels among 3325 participants, and incident HF hospitalization among 3633 participants with complete data. After adjustment for confounding factors, current smoking was associated with higher mean LV mass index and lower mean LV circumferential strain ( P <0.05, for both) in comparison with never smoking. Smoking status, intensity, and burden were associated with higher mean brain natriuretic peptide levels (all P <0.05). Over 8.0 years (7.7-8.0) median follow-up, there were 147 incident HF hospitalizations. After adjustment for traditional risk factors and incident coronary heart disease, current smoking (hazard ratio, 2.82; 95% confidence interval, 1.71-4.64), smoking intensity among current smokers (≥20 cigarettes/d: hazard ratio, 3.48; 95% confidence interval, 1.65-7.32), and smoking burden among ever smokers (≥15 pack-years: hazard ratio, 2.06; 95% confidence interval, 1.29-3.3) were significantly associated with incident HF hospitalization in comparison with never smoking. In blacks, cigarette smoking is an important risk factor for LV hypertrophy, systolic dysfunction, and incident HF hospitalization even after adjusting for effects on coronary heart disease. © 2018 American Heart Association, Inc.

Smoking is the most prevalent risk factor among young patients suffering acute myocardial infarction (AMI). In this review, we will present data on the detrimental consequences of continued smoking with regard to the recurrence of coronary events after an AMI at an early age. A prospective study with long-term follow-up of young survivors of AMI showed that continuation of smoking after a first episode of AMI was the strongest independent predictor of further cardiac events. In particular, persistent smokers had ∼2.5 times higher risk of a new coronary event when compared with nonsmokers. This emphasizes the fundamental importance of initiating smoking cessation treatment in all smokers with AMI during hospitalization. Extrapolating the results of previous studies showing the benefits of smoking cessation in middle-aged or elderly coronary patients, an even greater benefit should be expected in young patients because of their specific characteristics, which are presented in the current review. Young persistent smokers after a premature AMI constitute a high-risk subgroup for a recurrence of cardiac events. Therefore, smoking cessation is a key issue for improving their prognosis and all smokers should be offered effective antismoking treatment at the time of initial hospitalization.

Smoking is one of the most important risk factors for myocardial infarction. Smokers usually suffer their first myocardial infarction earlier in life compared to non-smokers. This age difference seems to be greater in women than in men. The aim of this study was to examine the age and sex differences in terms of smoking in patients with first myocardial infarction who were enrolled in the Swiss National Registry of myocardial infarction, AMIS Plus. Data of 15,711 patients admitted to an AMIS Plus hospital between 1999 and 2008 with a first myocardial infarction were analysed. Several multivariate regression, interaction and sensitivity analyses were conducted. The mean age at first myocardial infarction was 68.5 ± 12.2 years for non-smokers and 56.6 ± 11.7 years for smokers (P < 0.001). After stratification by sex the difference between non-smokers and smokers was 10.2 years in men and 13.1 years in women. Even after adjustment for risk factors (overweight, hypertension, dyslipidaemia, diabetes), comorbidities (peripheral vascular disease, cerebrovascular disease, chronic lung disease), regular cardiovascular medication intake before admission, Killip classification and ECG on admission, male smokers were 8.7 years younger than male non-smokers at first myocardial infarction. In women, the age difference between smokers and non-smokers was 10.8 years, giving a sex-specific difference of 2.1 years (P < 0.001). In the AMIS Plus cohort, smoking was associated with younger age at first myocardial infarction and this was much more pronounced in women. Public health campaigns should take into account the impact of smoking on premature first myocardial infarction, especially in women.

Introduction Oxidative stress and systemic inflammation are higher in smokers and patients with COPD; however, markers that may help differentiate between smokers and patients with COPD have not yet been identified. We hypothesized that tumor necrosis factor-alpha receptor (TNFR) and soluble form of the receptor for advanced glycation end products (sRAGE) can be indicators of COPD in asymptomatic patients. Patients and methods We evaluated 32 smokers (smoking history >10 pack-years), 32 patients with mild/moderate COPD (smokers and ex-smokers), and 32 never smokers. Concentrations of C-reactive protein (CRP), interleukin (IL)-6, TNFR1 and TNFR2, advanced glycation end products (AGEs), and the sRAGE were measured in serum. Results There were higher CRP and AGEs concentrations in smokers and in patients with COPD (P<0.001 and P=0.01, respectively) compared to controls, without statistical difference between smokers and patients with COPD. Concentrations of sRAGE, IL-6, and TNFR1 did not differ between study groups. TNFR2 was significantly higher in patients with COPD than in smokers (P=0.004) and controls (P=0.004), and the presence of COPD (P=0.02) and CRP (P=0.001) showed a positive association with TNFR2. Positive associations for smoking (P=0.04), CRP (P=0.03), and IL-6 (P=0.03) with AGEs were also found. The interaction variable (smoking × COPD) showed a positive association with IL-6. Conclusion Our data suggest that TNFR2 may be a possible marker of COPD in asymptomatic smokers and ex-smokers. Although smokers and patients with early COPD presented other increased systemic inflammation markers (eg, CRP) and oxidative stress (measured by AGEs), they did not differentiate smokers from COPD.

The Global Financial Crisis (GFC) increased levels of financial strain, especially in those of low socioeconomic status (SES). Financial strain can affect smoking behaviour. This study examines socioeconomic inequalities in current smoking and smoking cessation in The Netherlands before and during the Global Financial Crisis (GFC). Participants were 66,960 Dutch adults (≥ 18 years) who took part in the annual national Health Survey (2004-2011). Period was dichotomised: 'pre-' and 'during-GFC'. SES measures used were income, education and neighbourhood deprivation. Outcomes were current smoking rates (smokers/total population) and smoking cessation ratios (former smokers/ever smokers). Multilevel logistic regression models controlled for individual characteristics and tested for interaction between period and SES. In both periods, high SES respondents (in all indicators) had lower current smoking levels and higher cessation ratios than those of middle or low SES. Inequalities in current smoking increased significantly in poorly educated adults of 45-64 years of age (Odds Ratio (OR) low educational level compared with high: 2.00[1.79-2.23] compared to pre-GFC 1.67[1.50-1.86], p for interaction = 0.02). Smoking cessation inequalities by income in 18-30 year olds increased with borderline significance during the GFC (OR low income compared to high income: 0.73[0.58-0.91]) compared to pre-GFC (OR: 0.98[0.80-1.20]), p for interaction = 0.051). Overall, socioeconomic inequalities in current smoking and smoking cessation were unchanged during the GFC. However, current smoking inequalities by education, and smoking cessation inequalities by income, increased in specific age groups. Increased financial strain caused by the crisis may disproportionately affect smoking behaviour in some disadvantaged groups.

To investigate, using a Mendelian randomisation approach, whether heavier smoking is associated with a range of regional adiposity phenotypes, in particular those related to abdominal adiposity. Mendelian randomisation meta-analyses using a genetic variant (rs16969968/rs1051730 in the CHRNA5-CHRNA3-CHRNB4 gene region) as a proxy for smoking heaviness, of the associations of smoking heaviness with a range of adiposity phenotypes. 148,731 current, former and never-smokers of European ancestry aged ≥ 16 years from 29 studies in the consortium for Causal Analysis Research in Tobacco and Alcohol (CARTA). Waist and hip circumferences, and waist-hip ratio. The data included up to 66,809 never-smokers, 43,009 former smokers and 38,913 current daily cigarette smokers. Among current smokers, for each extra minor allele, the geometric mean was lower for waist circumference by -0.40% (95% CI -0.57% to -0.22%), with effects on hip circumference, waist-hip ratio and body mass index (BMI) being -0.31% (95% CI -0.42% to -0.19), -0.08% (-0.19% to 0.03%) and -0.74% (-0.96% to -0.51%), respectively. In contrast, among never-smokers, these effects were higher by 0.23% (0.09% to 0.36%), 0.17% (0.08% to 0.26%), 0.07% (-0.01% to 0.15%) and 0.35% (0.18% to 0.52%), respectively. When adjusting the three central adiposity measures for BMI, the effects among current smokers changed direction and were higher by 0.14% (0.05% to 0.22%) for waist circumference, 0.02% (-0.05% to 0.08%) for hip circumference and 0.10% (0.02% to 0.19%) for waist-hip ratio, for each extra minor allele. For a given BMI, a gene variant associated with increased cigarette consumption was associated with increased waist circumference.

The importance of smoking cessation interventions in lung cancer screening participants has been highlighted. This study aimed to describe the smoking habits of individuals who were ineligible for lung cancer screening and to investigate whether this encounter may represent an opportunity to reduce tobacco use. Ever smokers between the ages of 55 and 80 and ≥1.5% lung cancer risk over 6 years or having smoked ≥30 pack-years and with no more than 15 years of smoking abstinence were eligible to participate in the Alberta Lung Cancer Screening Program (ALCSP). A baseline questionnaire exploring tobacco use was administered to all interested individuals as part of the eligibility determination for the program. Among 504 individuals, 254 (50.4%) met the criteria for the ALCSP and 250 (49.6%) were non-eligible for screening. Non-eligible individuals were slightly younger (mean=60.2 vs. 63.1 years, p-value <0.001), and less likely to be current smokers (26.0% vs. 48.8%, p-value <0.001). Non-eligible smokers had a lower degree of addiction compared to eligible group, as measured by the Fagerström Test of Nicotine Dependence (Median=4.0 vs 6.0, p-value=0.001), but still in the "moderately dependent" range for this test. There were no significant differences in motivation to quit (98.5% vs. 97.6%, p-value=0.689), or motivation to receive help with their quit attempt (89.2% vs. 90.3%, p-value=0.813) between these two groups. Only 7.7% of non-eligible and 2.4% of eligible current smokers were currently in a smoking cessation program. A significant proportion of individuals applying to, but not qualifying for a lung cancer screening program are active smokers with significant nicotine dependence. Very few are currently participating in active smoking cessation programs but almost all are interested in quitting and in receiving help with quit attempts. Future studies need to investigate the most effective approaches for smoking cessation in this substantial group of older, long-term smokers, capitalizing on their motivation to receive cessation assistance.

Smoking is associated with an increased incidence of hormone receptor positive breast cancer. Data regarding worse breast cancer outcome in smokers are accumulating. Current literature regarding the impact of smoking on breast cancer characteristics is limited. We evaluated the impact of smoking on breast cancer characteristics and outcome. This was a retrospective single center study. All women diagnosed from 4/2005 through 3/2012 and treated in our institute for early, estrogen receptor positive, human epidermal growth factor receptor 2 (HER2) negative breast cancer, whose tumors were sent for Oncotype DX analysis were included. Medical records were reviewed for demographics, clinico-pathological parameters, treatment and outcome. Data regarding smoking were retrieved according to patients' history at the first visit in the oncology clinic. Patients were grouped and compared according to smoking history (ever smokers vs. never smokers), smoking status (current vs. former and never smokers) and smoking intensity (pack years ≥30 vs. the rest of the cohort). Outcomes were adjusted in multivariate analyses and included age, menopausal status, ethnicity, tumor size, nodal status and grade. A total of 662 women were included. 28.2% had a history of smoking, 16.6% were current smokers and 11.3% were heavy smokers. Smoking had no impact on tumor size, nodal involvement and Oncotype DX recurrence score. Angiolymphatic and perineural invasion rates were higher in current smokers than in the rest of the cohort (10.4% vs. 5.1%, p = 0.045, 8.3% vs. 3.5%, p = 0.031, respectively). Smoking had no other impact on histological characteristics. Five-year disease free survival and overall survival rates were 95.7% and 98.5%, respectively. Smoking had no impact on outcomes. Adjusted disease free survival and overall survival did not influence the results. Smoking had no clinically significant influence on tumor characteristics and outcome among women with estrogen receptor positive, HER2 negative, early breast cancer. As the study was limited to a specific subgroup of the breast cancer population in this heterogeneous disease and since smoking is a modifiable risk factor for the disease, further research is required to clarify the possible impact of smoking on breast cancer.

Objective The World Health Organization recommends that smokers be offered help to quit. A better understanding of smokers’ interest in and commitment to quitting could guide tobacco control efforts. We assessed temporal differences in stages of change toward quitting among smokers in Thailand and Turkey. Methods Two waves (independent samples) of data from the Global Adult Tobacco Survey, a national household survey of adults aged 15 years or older, were assessed for Thailand (2009 and 2011) and Turkey (2008 and 2012). Current smokers were categorized into 3 stages of change based on their cessation status: precontemplation, contemplation, and preparation. Relative change in the proportion of smokers in each stage between waves 1 and 2 was computed for each country. Results Between waves, overall current tobacco smoking did not change in Thailand (23.7% to 24.0%) but declined in Turkey (31.2% to 27.1%; P < .001). Between 2009 and 2011, precontemplation increased among smokers in Thailand (76.1% to 85.4%; P < .001), whereas contemplation (17.6% to 12.0%; P < .001) and preparation (6.3% to 2.6%; P < .001) declined. Between 2008 and 2012, there were declines in precontemplation among smokers in Turkey (72.2% to 64.6%; P < .001), whereas there were increases in contemplation (21.2% to 26.9%; P = .008) and no significant change in preparation (6.5% to 8.5%; P = .097). Conclusion Nearly two-thirds of smokers in Turkey and more than two-thirds in Thailand were in the precontemplation stage during the last survey wave assessed. The proportion of smokers in the preparation stage increased in Turkey but declined in Thailand. Identifying stages of cessation helps guide population-based targeted interventions to support smokers at varying stages of change toward quitting. PMID:28570209

A questionnaire survey of 713 pupils of Secondary Schools in Bo town, Southern Sierra Leone, on tobacco and cannabis smoking was carried out in January and February 1994. There were 56.8% males and 43.2% females with a mean age of 17.6 +/- 1.5 years. Lifetime use of both substances was 9% while current use was 4.2%. Current use of cigarettes was 3.2% and of cannabis 2.2%. Forty percent of current users smoked both cigarettes and cannabis. The mean age of onset of smoking was 15.1 +/- 3.1 years. Males smoked significantly more than females (p < 0.001). The prevalence of smoking increased with age and from junior to senior forms. There was also a higher prevalence among muslim students. Smoking within the family was a significant determinant of smoking in School children (p < 0.01). Current smokers were less aware of the health hazards of smoking but the majority of previous smokers stopped the habit because they thought it was bad for their health. In spite of these relatively rates, it is recommended that appropriate health education programme on tobacco and cannabis smoking be incorporated into school curricula. Further studies are indicated in more urbanized areas and in colleges.

Mind-body interventions can improve vulnerabilities that underlie smoking behavior. The characteristics of smokers who use mind-body medicine have not been explored, preventing the development of targeted interventions. Patients ( N = 593) presenting to a mind-body medicine clinic completed self-report measures. Patients were 67 percent never smokers, 27 percent former smokers, and 6 percent current smokers. Current smokers were younger; more likely to be single, unemployed, or on disability; and report greater depression symptoms, greater pain, and lower social support ( ps < .05).Current smokers who use mind-body medicine have unique psychosocial needs that should be targeted in mind-body smoking cessation interventions.

Repeated drug use modifies the emotional and cognitive processing of drug-associated cues. These changes are supposed to persist even after prolonged abstinence. Several studies demonstrated that smoking cues selectively attract the attention of smokers, but empirical evidence for such an attentional bias among successful quitters is inconclusive. Here, we investigated whether attentional biases persist after smoking cessation. Thirty-eight former smokers, 34 current smokers, and 29 non-smokers participated in a single experimental session. We used three measures of attentional bias for smoking stimuli: A visual probe task with short (500ms) and long (2000ms) picture stimulus durations, and a modified Stroop task with smoking-related and neutral words. Former smokers and current smokers, as compared to non-smokers, showed an attentional bias in visual orienting to smoking pictures in the 500ms condition of the visual probe task. The Stroop interference index of smoking words was negatively related to nicotine dependence in current smokers. Former smokers and mildly dependent smokers, as compared to non-smokers, showed increased interference by smoking words in the Stroop task. Neither current nor former smokers showed an attentional bias in maintained attention (2000ms visual probe task). In conclusion, even after prolonged abstinence smoking cues retain incentive salience in former smokers, who differed from non-smokers on two attentional bias indices. Attentional biases in former smokers operate mainly in early involuntary rather than in controlled processing, and may represent a vulnerability factor for relapse. Therefore, smoking cessation programs should strengthen self-control abilities to prevent relapses. Copyright © 2017 Elsevier B.V. and ECNP. All rights reserved.

While smokers are known to find smoking-related stimuli to be motivationally salient, the extent to which former smokers do so is largely unknown. In this study, we collected event-related potential (ERP) data from former and never smokers and compared them to a sample of current smokers interested in quitting who completed the same ERP paradigm prior to smoking cessation treatment. All participants (n = 180) attended one laboratory session where we recorded dense-array ERPs in response to cigarette-related, pleasant, unpleasant, and neutral pictures, and where we collected valence and arousal ratings of the pictures. We identified three spatial and temporal regions of interest, corresponding to the P1 (120-132 ms), early posterior negativity (EPN; 244-316 ms), and late positive potential (LPP; 384-800 ms) ERP components. We found that all participants produced larger P1 responses to cigarette-related pictures compared to the other picture categories. With the EPN component, we found that, similar to pleasant and unpleasant pictures, cigarette-related pictures attracted early attentional resources, regardless of smoking status. Both former and never smokers produced reduced LPP responses to cigarette-related and pleasant pictures compared to current smokers. Current smokers rated the cigarette-related pictures as being more pleasant and arousing than the former and never smokers. The LPP and picture rating results suggest that former smokers, like never smokers, do not find cigarette-related stimuli to be as motivationally salient as current smokers. PMID:25436840

Physical activity has been identified as a protective factor with regard to tobacco use, such that physically active adolescents are less likely to initiate smoking, and smokers are less physically active than non-smokers. These findings, along with the well-documented benefits of exercise on mood and well-being in adults, have stimulated interest in exercise-based smoking cessation interventions. However, little research has explored the relationship between physical activity and smoking characteristics within adolescent smokers. Also, gender differences in adolescents’ motives for smoking and exercise may have implications for intervention development, especially in clinical populations. The current study explored the relationship between physical activity and smoking in a sample of adolescent smokers (N = 191) and non-smokers (N = 48) receiving inpatient psychiatric treatment (61% female, mean age 15.3 years). Results indicated that smokers were less likely to be physically active than non-smokers. Additionally, there was a consistent pattern of gender differences in the relationship between smoking and physical activity within smokers. Specifically, physically active male smokers were less nicotine dependent and less prone to withdrawal, and had a trend toward greater motivation to quit, than their non-active counterparts. In contrast, physically active female smokers did not differ in dependence or withdrawal and were less motivated to quit than non-active female smokers. Taken together, these results suggest that within clinical populations of adolescent females, smoking and exercise may be used jointly as weight control strategies. Exercise-based interventions for smoking cessation for adolescent females, especially clinical populations, should address weight and body image concerns. PMID:23459125

Anxiety sensitivity (AS), defined as the extent to which individuals believe that anxiety-related sensations have harmful consequences, is associated with smoking processes and poorer clinical outcomes among trauma-exposed smokers. Yet the specific mechanisms underlying this association are unclear. Smoking-specific avoidance and inflexibility is a construct implicated in multiple manifestations of mood regulation that may underlie smoking behavior. The current study examined the explanatory role of smoking-specific avoidance and inflexibility in terms of the relation between AS and indices of smoking behavior among trauma-exposed smokers. The sample consisted of 217 treatment-seeking adult smokers (44% female; M age = 37.8; SD = 13.2; age range: 18-65 years), who were exposed to at least one lifetime Criterion A trauma event (Diagnostic and Statistical Manual of Mental Disorders [4th ed., text rev.; DSM-IV-TR] Criterion A for trauma exposure). Bootstrap analysis (5,000 re-samples) revealed that AS was indirectly related to the (a) number of cigarettes smoked per day, (b) number of years being a daily smoker, (c) number of failed quit attempts, and (d) heaviness of smoking index among trauma-exposed smokers through its relation with smoking-specific avoidance and inflexibility. These findings provide initial evidence suggesting that smoking-specific avoidance and inflexibility may be an important construct in better understanding AS-smoking relations among trauma-exposed smokers. Future work is needed to explore the extent to which smoking-specific avoidance and inflexibility account for relations between AS and other smoking processes (e.g., withdrawal, cessation outcome) in the context of trauma and smoking comorbidity. © The Author(s) 2015.

Our study aimed to investigate the effect of cigarette smoking on the clinical phenotype of patients registered in the Chinese Systemic Lupus Erythematosus (SLE) Treatment and Research (CSTAR) group registry database, the first online registry of Chinese patients with SLE. A prospective cross-sectional study of Chinese SLE patients was conducted using the CSTAR. Our case-control analysis was performed on age- and gender-matched subjects to explore the potential effect of cigarette smoking on the clinical manifestation of SLE. Smokers comprised 8.9% (65/730) of patients, and the ratio of females/males was 19/46. Thirty-nine patients were current smokers, and 26 were ex-smokers. Data showed significant differences between smokers and nonsmokers in the following areas: nephropathy (58.5% vs. 39.2%; p = 0.003), microscopic hematuria (30.8% vs. 19.1%; p = 0.025), proteinuria (53.8% vs. 34.4%; p = 0.002), and SLE Disease Activity Index(DAI) scores (12.38±8.95 vs. 9.83±6.81; p = 0.028). After adjusting for age and gender, significant differences between smokers and nonsmokers were found with photosensitivity (35.9% vs. 18%; p = 0.006), nephropathy (59.4% vs. 39.8%; p = 0.011), and proteinuria (54.7% vs. 35.2%). Although smokers tended to have greater disease severity compared with nonsmokers (SLEDAI scores: 12.58±8.89 vs.10.5±7.09), the difference was not significant (p = 0.081). Cigarette smoking triggers the development and exacerbation of SLE, especially with respect to renal involvement. Chinese smokers with SLE should be advised to discontinue cigarette use.

Many persons misidentify the quality of taste stimuli, a phenomenon termed "taste confusion." In this study of 1000 persons, we examined the influences of age, sex, causes of chemosensory disturbances, and genetically determined phenylthiocarbamide (PTC) taster status on taste quality confusions for four tastants (sucrose, citric acid, sodium chloride, caffeine). Overall, sour-bitter confusions were most common (19.3%), followed by bitter-sour (11.4%), salty-bitter (7.3%), salty-sour (7.0%), bitter-salty (3.5%), bitter-sweet (3.4), and sour-salty (2.4%) confusions. Confusions for sweet were <1%. Asymmetries were common (e.g., bitter-sour confusions were less frequent than sour-bitter confusions). Women had fewer salty-bitter confusions than did men (5.7% vs. 11.4%). Overall, PTC tasters had fewer confusions than non-tasters except for salty-bitter confusions. Confusions typically increased monotonically with age. Current smokers exhibited more sour-bitter confusions than never smokers (48.9% vs. 32.2%), whereas past smokers had more bitter-sour confusions than never smokers (23.8% vs. 14.2%). Previous head trauma was associated with higher bitter-salty and salty-bitter confusions relative to those of some other etiologies. This study demonstrates, for the first time, that multiple subject factors influence taste confusions and, along with literature accounts, supports the view that there are both biological and psychological determinants of taste quality confusions.

Currently, the diagnosis of chronic obstructive pulmonary disease (COPD) requires a ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) of less than 0.70 as assessed by spirometry after bronchodilator use. However, many smokers who do not meet this definition have respiratory symptoms. We conducted an observational study involving 2736 current or former smokers and controls who had never smoked and measured their respiratory symptoms using the COPD Assessment Test (CAT; scores range from 0 to 40, with higher scores indicating greater severity of symptoms). We examined whether current or former smokers who had preserved pulmonary function as assessed by spirometry (FEV1:FVC ≥0.70 and an FVC above the lower limit of the normal range after bronchodilator use) and had symptoms (CAT score, ≥10) had a higher risk of respiratory exacerbations than current or former smokers with preserved pulmonary function who were asymptomatic (CAT score, <10) and whether those with symptoms had different findings from the asymptomatic group with respect to the 6-minute walk distance, lung function, or high-resolution computed tomographic (HRCT) scan of the chest. Respiratory symptoms were present in 50% of current or former smokers with preserved pulmonary function. The mean (±SD) rate of respiratory exacerbations among symptomatic current or former smokers was significantly higher than the rates among asymptomatic current or former smokers and among controls who never smoked (0.27±0.67 vs. 0.08±0.31 and 0.03±0.21 events, respectively, per year; P<0.001 for both comparisons). Symptomatic current or former smokers, regardless of history of asthma, also had greater limitation of activity, slightly lower FEV1, FVC, and inspiratory capacity, and greater airway-wall thickening without emphysema according to HRCT than did asymptomatic current or former smokers. Among symptomatic current or former smokers, 42% used bronchodilators and 23% used inhaled glucocorticoids. Although they do not meet the current criteria for COPD, symptomatic current or former smokers with preserved pulmonary function have exacerbations, activity limitation, and evidence of airway disease. They currently use a range of respiratory medications without any evidence base.

There is a need to identify sensitive biomarkers of early tobacco-related cardiovascular disease. We examined the association of smoking status, burden, time since quitting, and intensity, with markers of inflammation and subclinical atherosclerosis. We studied 14 103 participants without clinical cardiovascular disease in ELSA-Brasil (Brazilian Longitudinal Study of Adult Health). We evaluated baseline cross-sectional associations between smoking parameters and inflammation (high-sensitivity C-reactive protein [hsCRP]) and measures of subclinical atherosclerosis (carotid intima-media thickness, ankle-brachial index, and coronary artery calcium [CAC]). The cohort included 1844 current smokers, 4121 former smokers, and 8138 never smokers. Mean age was 51.7±8.9 years; 44.8% were male. After multivariable adjustment, compared with never smokers, current smokers had significantly higher levels of hsCRP (β=0.24, 0.19-0.29 mg/L; P <0.001) and carotid intima-media thickness (β=0.03, 0.02-0.04 mm; P <0.001) and odds of ankle-brachial index ≤1.0 (odds ratio: 2.52; 95% confidence interval, 2.06-3.08; P <0.001) and CAC >0 (odds ratio: 1.83; 95% confidence interval, 1.46-2.30; P <0.001). Among former and current smokers, pack-years of smoking (burden) were significantly associated with hsCRP ( P <0.001 and P =0.006, respectively) and CAC ( P <0.001 and P =0.002, respectively). Among former smokers, hsCRP and carotid intima-media thickness levels and odds of ankle-brachial index ≤1.0 and CAC >0 were lower with increasing time since quitting ( P <0.01). Among current smokers, number of cigarettes per day (intensity) was positively associated with hsCRP ( P <0.001) and CAC >0 ( P =0.03) after adjusting for duration of smoking. Strong associations were observed between smoking status, burden, and intensity with inflammation (hsCRP) and subclinical atherosclerosis (carotid intima-media thickness, ankle-brachial index, CAC). These markers of early cardiovascular disease injury may be used for the further study and regulation of traditional and novel tobacco products. © 2017 The Authors.

ABSTRACT Background: Understanding how people transition between phases of not making a quit attempt to stopping smoking successfully is important in order to optimize interventions. This study aimed to explore differences in attitudes towards smoking and quitting among smokers and ex-smokers. Methods: Adult (age 18 and over) successful (n = 8), unsuccessful (n = 8) and never quitters (n = 7) were recruited through stop-smoking services in England. Semi-structured interviews were conducted and data were analysed using framework analysis. Results: Seven themes (starting to smoke, positive appraisal of smoking, responsibility for past/current smoking, negative effects of smoking, reasons to quit, process of quitting, and identity) were identified in all groups. Sub-group differences were explored and used to derive six typologies with descriptive characteristics: committed smokers, aware smokers, forced attempters, struggling attempters, pragmatic ex-smokers, and committed non-smokers. Using these typologies and the smallest number of differentiating factors between them (awareness of negative effects, motivation to stop and acceptance of responsibility), a parsimonious model of progression towards smoking cessation was developed. Conclusions: Awareness of negative effects, motivation and, crucially, a sense of commitment for taking responsibility to take actions towards behavior change may be important for whether smokers attempt to quit and progress to a successful quit attempt.

Cigarette smoking is a major cause of morbidity and mortality. The association between smoking and eye diseases is less widely recognised relative to other better-known smoking-related conditions. This study aims to assess the awareness and fear of known smoking-related diseases among current smokers attending an ophthalmology outpatient clinic and to evaluate their relative impact on the likelihood of smoking cessation. A cross-sectional survey using a structured interview of randomly selected current smokers attending an eye clinic was conducted. The knowledge of six smoking-related diseases (lung cancer, heart attack, stroke, blindness, other cancers, and other lung diseases) was assessed. The fear of smoking-related conditions and the relative impact of each smoking-related condition on the smoker's motivation to quit smoking were evaluated. Out of 200 current smokers aged from 14 to 83 years, only 42.5% (85 patients) were aware that smoking causes blindness. Smokers' perception of harm caused by smoking was 6.53±3.21 (mean±SD) on a visual analogue scale of 0 to 10. Patients placed blindness as the second most important motivating factor to quit smoking immediately, within 1 year and 5 years, after lung cancer. The awareness of the risk of blindness from smoking was lowest compared with five other smoking-related diseases among eye patients who smoke. However, blindness remains a key motivational factor in smoking cessation and hence should be emphasised as an important negative health consequence of smoking in public health education and anti-smoking campaigns.

Objective Young adults frequently report social smoking. This study examined the relationship between different social smoking definitions and the co-use of cigarettes and alcohol, tobacco-related attitudes, and quitting efforts. Method Cross-sectional data were collected at bars using randomized time location sampling among young adults aged 21–26 in San Diego, CA from 2010–2011 (73% response rate). Multivariable logistic regression examined if current smoking and quit attempts were associated with tobacco-related attitudes, and whether social smoking self-identification or behavior was associated with cigarette-and-alcohol co-use, tobacco-related attitudes, quit attempts, or quitline use. Results Among 537 current smokers, 80% self-identified and 49% behaved as social smokers. Social smoking self-identification was positively associated with cigarette-and-alcohol co-use, and quit attempts. Social smoking behavior was negatively associated with tobacco marketing receptivity, quit attempts, quitline use. Tobacco-related attitudes were associated with smoking but did not generally differ by social smoking status. Conclusion Identification and behavior as a social smoker have opposing associations with co-use of cigarettes and alcohol and quit attempts. Tobacco cessation programs for self-identified social smokers should address co-use. Interventions denormalizing the tobacco industry or emphasizing the health effects of temporary smoking/secondhand smoke may address smoking among young adult bar patrons regardless of social smoking status.

The objective of this study was to examine the association between individual satisfaction with social and physical surroundings and the habit of smoking cigarettes. Data from the Health Survey of Adults from the metropolitan area of Belo Horizonte, Minas Gerais, Brazil, were used. Based on a probability sample, participants (n = 12,299) were selected among residents aged 20 years old or more. The response variable was the smoking habit and the explanatory variable of interest was the neighborhood perception. Potential confounding variables included demographic characteristics, health behaviors and other indicators of socioeconomic position. The prevalence of current smokers, former smokers and never smokers were 20.8, 14.1 and 65.1%, respectively; 74.4 and 25.5% of the participants were categorized as being more satisfied and less satisfied with the neighborhood, respectively. Compared to those who never smoked, former smokers (adjusted odds ratio = 1.40, 95% confidence interval 1.20 - 1.62) and current smokers (adjusted odds ratio = 1.17, 95% confidence interval 1.03 - 1.34) were less satisfied with the neighborhood compared to those who never smoked. The results of this study indicate there is an independent association between the smoking habit and a less satisfying neighborhood perception in the metropolitan region of Belo Horizonte, which does not depend on individual characteristics, traditionally reported as being associated with smoking.

Objective Identification of challenges associated with quitting and overcoming them may improve cessation outcomes. This study describes the development and initial validation of a scale for measuring challenges to stopping smoking. Methods The item pool was generated from empirical and theoretical literature and existing scales, expert opinion and interviews with smokers and ex-smokers. The questionnaire was administered to smokers and recent quitters who participated in a hospital-based smoking cessation trial. Exploratory factor analysis was performed to identify subscales in the questionnaire. Internal consistency, validity and robustness of the subscales were evaluated. Results Of a total of 182 participants with a mean age of 55 years (SD 12.8), 128 (70.3%) were current smokers and 54 (29.7%) ex-smokers. Factor analysis of the 21-item questionnaire resulted in a 2-factor solution representing items measuring intrinsic (9 items) and extrinsic (12 items) challenges. This structure was stable in various analyses and the 2 factors accounted for 50.7% of the total variance of the polychoric correlations between the items. Internal consistency (Cronbach's α) coefficients for the intrinsic and extrinsic subscales were 0.86 and 0.82, respectively. Compared with ex-smokers, current smokers had a higher mean score (±SD) for intrinsic (24.0±6.4 vs 20.5±7.4, p=0.002) and extrinsic subscales (22.3±7.5 vs 18.6±6.0, p=0.001). Conclusions Initial evaluation suggests that the 21-item challenges to stopping smoking scale is a valid and reliable instrument that can be used in research and clinical settings to assess challenges to stopping smoking.

To estimate smoking progression probabilities from adolescence to young adulthood and to estimate long-term health and medical cost impacts of preventing smoking in today's adolescents. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we first estimated smoking progression probabilities from adolescence to young adulthood. Then, using the predicted probabilities, we estimated the number of adolescents who were prevented from becoming adult daily smokers as a result of a hypothetical 1 percentage point reduction in the prevalence of ever smoking in today's adolescents. We further estimated lifetime medical costs saved and quality-adjusted life years (QALYs) gained as a result of preventing adolescents from becoming adult daily smokers. All costs were in 2010 dollars. Compared with never smokers, those who had tried smoking at baseline had higher probabilities of becoming current or former daily smokers at follow-up regardless of baseline grade or sex. A hypothetical 1 percentage point reduction in the prevalence of ever smoking in 24.5 million students in 7th-12th grades today could prevent 35,962 individuals from becoming a former daily smoker and 44,318 individuals from becoming a current daily smoker at ages 24-32 years. As a result, lifetime medical care costs are estimated to decrease by $1.2 billion and lifetime QALYs is estimated to increase by 98,590. Effective smoking prevention programs for adolescents go beyond reducing smoking prevalence in adolescence; they also reduce daily smokers in young adulthood, increase QALYs, and reduce medical costs substantially in later life. This finding indicates the importance of continued investment in effective youth smoking prevention programs. Published by Elsevier Inc.

This study reports the prevalence of electronic cigarette (e-cigarette) use among adolescents in Greece and explores how dual smokers of e-cigarettes and combustible (conventional) cigarettes differ from smokers of only combustible cigarettes across socio-demographic, familial, psychosomatic health and substance use characteristics. Self-reports on smoking were collected from a nationally representative sample of 1320 15-year-old Greek students in the 2014 Health Behaviour in School-aged Children study. Bivariate and multivariable logistic regression analyses were carried out with dependent variables a) lifetime smoking conventional cigarettes and b) lifetime e-cigarette use among lifetime smokers. About 36.9% of 15-year-olds reported lifetime smoking of conventional cigarettes, and 16.6% lifetime use of e-cigarettes, mostly experimenting (0.5% reported current e-cigarette use). Six in 7 ever e-cigarette smokers had smoked conventional cigarettes. Peers who smoke and lifetime cannabis use were significant correlates of both lifetime conventional cigarette and e-cigarette smoking, but more strongly for smoking conventional cigarettes. Alcohol use and low parental monitoring correlated with tobacco smoking but not e-cigarette use. Girls were more likely than boys to report lifetime use of tobacco, but, among lifetime smokers, boys had almost seven times the odds of girls of e-cigarette use. In lifetime smokers, low life satisfaction in females and current smoking of conventional tobacco were independently associated with the experimentation with e-cigarettes. Experimental use of e-cigarettes is relatively widespread among adolescents in Greece. Targeted interventions should focus on male smokers and the role of peer processes and cannabis use in the risk of experimenting with e-cigarettes. Copyright © 2015 Elsevier Ltd. All rights reserved.

The research of light (≤10 cigarettes per day) and non-daily smokers in developing countries including Brazil is scarce despite the high prevalence of these groups among smokers and health risks associated to low-level smoking. To describe health and smoking characteristics of Brazilian adult light and non-daily smokers. We analyzed data from the 2013 Brazilian National Health Research survey (n=48,282). The prevalence of current manufactured cigarette smoking in the total sample was 12.4%. Among these smokers, 12.8% were non-daily smokers (NDS), 47.4% were light smokers (LS) and 39.8% were moderate/heavy smokers (MHS). Bivariate analysis showed that non-daily smoking was associated with higher odds of poor self-rated health, binge drinking and lung diseases compared to never smokers (ORs=1.2; 5.9 and 1.9). Light smoking was associated with higher odds of poor self-rated health, binge drinking, depression, use of sleeping pills and lung diseases (ORs=1.3; 4.3; 1.4; 1.2 and 2.0). After controlling for sex and age, non-daily smoking was associated with lung disease (OR=2.2) and light smoking with depression and lung diseases (ORs=1.3 and 1.8). Smoking levels were associated with living with same-level smokers in bivariate and multivariate analyses. A large proportion of smokers in Brazil are light and non-daily smokers, carrying substantial health risks related to tobacco use. Longitudinal research is needed to provide further evidence of associations found in this study. Public health policies must take the different smoking patterns into consideration to effectively target all smokers and reduce the harmful consequences of tobacco worldwide.

In countries where smoking is associated with lower socioeconomic status, smokers tend to perform worse on cognitive tasks than non-smokers. China is now undergoing a similar process with a recent study showing that there is a reduced cognitive performance in middle aged but not in elderly smokers. We examined the links between smoking status and cognitive functioning among vocational school students in Beijing, China. A total of 213 students aged 16-20 (98 smokers and 115 non-smokers) were recruited from three vocational schools in Beijing. Participants completed three subtests of Wechsler Adult Intelligence Scale (WAIS) (information, arithmetic, digit span) and Dysexecutive Questionnaire (DEX). Smokers also completed a cigarette smoking questionnaire and Fagerstrom Test of Nicotine Dependence (FTND). Smokers performed worse than non-smokers in tests of arithmetic and digit span forward (t = 4.25, 2.05, both P < .05). Scores on digit span backward did not differentiate smokers and non-smokers, but among smokers, the performance on this subtest was related to the age of starting smoking (r = 0.26, p < .001). Cognitive performance in smokers was not related to tobacco dependence or intensity of smoking. Compared to non-smokers, smokers had a higher total DEX score and higher scores on three of its five subscales (Inhibition, Knowing-doing dissociation and Social regulation, all p < .05). Another subscale, In-resistance, did not differentiate smokers and non-smokers, but differentiated smokers with lower and higher levels of nicotine dependence (t = -2.12, p < .05). Smokers performed worse on some cognitive tasks than non-smokers and scored higher on a questionnaire assessing executive dysfunction. Copyright © 2017. Published by Elsevier Ltd.

A growing proportion of US smokers now smoke fewer than 10 cigarettes per day (CPD), and that proportion will likely rise in the future. The health effects of smoking only a few CPD over one's lifetime are less understood than are the effects of heavier smoking, although many smokers believe that their level is modest. To evaluate the associations of long-term smoking of fewer than 1 or 1 to 10 CPD (low intensity) with all-cause and cause-specific mortality compared with never smoking cigarettes. Prospective cohort study of 290 215 adults in the National Institutes of Health-AARP (formerly known as the American Association of Retired Persons) Diet and Health Study who were aged 59 to 82 years in calendar years 2004-2005 (baseline). Data were gathered with a questionnaire assessing lifetime cigarette smoking history. Hazard ratios (HRs) and 95% CIs were determined for all-cause mortality and cause-specific mortality through the end of 2011. Hazard ratios and 95% CIs were estimated using Cox proportional hazards regression models using age as the underlying time metric and adjusted for sex, race/ethnicity, educational level, physical activity, and alcohol intake. Data analysis was conducted from December 15, 2015, to September 30, 2016. Current and historical smoking intensity during 9 previous age periods (from <15 years to ≥70 years) over the lifetime assessed on the 2004-2005 questionnaire. All-cause and cause-specific mortality among current, former, and never smokers. Of the 290 215 cohort participants who completed the 2004-2005 questionnaire, 168 140 were men (57.9%); the mean (SD) age was 71 (5.3) years (range, 59-82 years). Most people who smoked fewer than 1 or 1 to 10 CPD at baseline reported smoking substantially higher numbers of CPD earlier in their lives. Nevertheless, 159 (9.1%) and 1493 (22.5%) of these individuals reported consistently smoking fewer than 1 or 1 to 10 CPD in each age period that they smoked, respectively. Relative to never smokers, consistent smokers of fewer than 1 CPD (HR, 1.64; 95% CI, 1.07-2.51) and 1 to 10 CPD (HR, 1.87; 95% CI, 1.64-2.13) had a higher all-cause mortality risk. Associations were similar in women and men for all-cause mortality and were observed across a range of smoking-related causes of death, with an especially strong association with lung cancer (HR, 9.12; 95% CI, 2.92-28.47, and HR, 11.61; 95% CI, 8.25-16.35 for <1 and 1-10 CPD, respectively). Former smokers who had consistently smoked fewer than 1 or 1 to 10 CPD had progressively lower risks with younger age at cessation. For example, the HRs for consistent smokers of fewer than 1 and 1 to 10 CPD who quit at 50 years or older were 1.44 (95% CI, 1.12-1.85) and 1.42 (95% CI, 1.27-1.59), respectively. This study provides evidence that individuals who smoke fewer than 1 or 1 to 10 CPD over their lifetime have higher mortality risks than never smokers and would benefit from cessation. These results provide further evidence that there is no risk-free level of exposure to tobacco smoke.

IMPORTANCE A growing proportion of US smokers now smoke fewer than 10 cigarettes per day (CPD), and that proportion will likely rise in the future. The health effects of smoking only a few CPD over one’s lifetime are less understood than are the effects of heavier smoking, although many smokers believe that their level is modest.

This research examined the fundamental frequency and perturbation (jitter % and shimmer %) measures in young adult (20-30 year-old) and middle-aged adult (40-55 year-old) smokers and non-smokers; there were 36 smokers and 36 non-smokers. Acoustic analysis was carried out utilizing one task: production of sustained /a/. These voice samples were analyzed utilizing Multi-Dimensional Voice Program (MDVP) software, which provided values for fundamental frequency, jitter %, and shimmer %.These values were analyzed for trends regarding smoking status, age, and gender. Statistical significance was found regarding the fundamental frequency, jitter %, and shimmer % for smokers as compared to non-smokers; smokers were found to have significantly lower fundamental frequency values, and significantly higher jitter % and shimmer % values. Statistical significance was not found regarding fundamental frequency, jitter %, and shimmer % for age group comparisons. With regard to gender, statistical significance was found regarding fundamental frequency; females were found to have statistically higher fundamental frequencies as compared to males. However, the relationships between gender and jitter % and shimmer % lacked statistical significance. These results indicate that smoking negatively affects voice quality. This study also examined the ability of untrained listeners to identify smokers and non-smokers based on their voices. Results of this voice perception task suggest that listeners are not accurately able to identify smokers and non-smokers, as statistical significance was not reached. However, despite a lack of significance, trends in data suggest that listeners are able to utilize voice quality to identify smokers and non-smokers.

INTRODUCTION: In 1996 we conducted a cross-sectional survey to study the epidemiology of smoking among Kuwaiti adults. METHODS: The 4000 participants were selected using a three-stage stratified cluster sampling design. Altogether 3859 participants (1798 males, 2061 females) returned a completed self-administered questionnaire. RESULTS: The prevalence of smoking was 34.4% (95% confidence interval (CI) = 32.2-36.6) among men and 1.9% (95% CI = 1.3-2.5) among women. Among men, the highest prevalence (56.5%; 95% CI = 36.2-76.8) was observed in the youngest age group (< or = 20 years). Among women the highest prevalence was observed in one of the older age groups (46-50 years) (7.1%; 95% CI = 3.1-11.1). Multiple logistic regression analysis showed that the following factors were independently associated with smoking: lower levels of education (odds ratio (OR) 3.5; 95% CI = 1.5-8.4), lower employment grade (OR = 4.1; 2.5-6.7), and being a separated, divorced, or widowed woman (OR = 4.9; 95% CI = 2.0-11.8). The majority of smokers (68%) began smoking when younger than 20 years; significantly more men (70%) than women (33%) began smoking at these ages (P < 0.0001). On average, men began smoking at an earlier age (18 years vs 21 years; P < 0.001) and therefore had smoked for a longer period (15 years vs 12 years; P < 0.05); men also consumed a higher number of cigarettes each day (26 vs 17; P < 0.05). A large proportion of smokers were ignorant about the health consequences of passive smoking: about 77% of those with children reported that they smoked in the presence of their children. Almost half (47%) of all smokers stated that they wanted to stop smoking, and about 56% had attempted to quit. The biggest perceived barrier to quitting was uncertainty about "how to quit". A total of 338 respondents (8.8%; 95% CI = 5.8-11.9) were classified as former smokers. About half of the former smokers had quit between the ages of 20 and 29 years; the average age of quitting was 28 years. Former smokers were more likely to have smoked fewer cigarettes per day and to have smoked for significantly less time than current smokers. DISCUSSION: Given the fact that free education is provided at all levels by the government, anti-tobacco education and awareness should be included as an integral part of the curriculum in schools and colleges.

Introduction Rheumatoid arthritis (RA) is associated with altered metabolism leading to muscle wasting. In the general population, cigarette smoking is known to affect body composition by reducing fat and inhibiting muscle synthesis. Even though smoking has been implicated in the pathophysiology and progression of RA, its possible effects on body composition of such patients have not been studied. This cross-sectional study aimed to identify potential associations of smoking with body weight and composition of RA patients. Methods A total of 392 patients (290 females) with RA were assessed for body mass index (BMI), body fat (BF), fat-free mass (FFM), and waist circumference. Erythrocyte sedimentation rate, C-reactive protein, Disease Activity Score-28, and Health Assessment Questionnaire score were used to assess disease activity and severity. Smoking habit (current smoker, ex-smoker, or never-smoker) and intensity (pack-years) were also noted. Results Current smokers had a significantly lower BMI compared with ex-smokers (mean difference: male -2.6, 95% confidence interval [CI]: -3.5 to -1.7; female: -2.6, 95% CI: -4.8 to -0.5) and never-smokers (mean difference: male -1.8, 95% CI: -3 to -0.6; female: -1.4, 95% CI: -2.4 to -0.4). Similarly, the BF of current smokers was lower compared with that of ex-smokers (mean difference: male: -4.3, 95% CI: -7.5 to -1.2; female: -3.4, 95% CI: -6.4 to -0.4) and never-smokers (mean difference: male: -3.3, 95% CI: -6.3 to -0.4; female: -2.1, 95% CI: -4 to -0.2). FFM did not differ between groups. Finally, current smokers had a significantly smaller waist circumference compared with ex-smokers only (mean difference: male: -6.2, 95% CI: -10.4 to -1.9; female: -7.8, 95% CI: -13.5 to -2.1). Following adjustments for age, disease duration, and HAQ score, smoking remained a significant predictor for BMI (P < 0.001), BF (P < 0.05), and waist circumference (P < 0.05). Pack-years were inversely correlated with BF (r = -0.46; P < 0.001), and heavy smokers exhibited a significantly lower FFM (P < 0.05) compared with all other participants. Conclusion Within the limitations of a cross-sectional study, it appears that cigarette smoking associates with reduced BMI and BF in patients with RA and heavy smoking associates with lower muscle mass. Smoking cessation appears to associate with increased BMI, BF, and waist circumference in these patients. These results should be confirmed in prospective studies. Given the numerous adverse effects of smoking on general health and RA, patients should be actively advised against it. However, smoking cessation regimes in RA may need to include more general lifestyle counselling, particularly about weight control. PMID:18492239

Approximately 30% of patients undergoing elective general surgery smoke cigarettes. The association between smoking status and hospital costs in general surgery patients is unknown. The objectives of this study were to compare total inpatient costs in current smokers, former smokers, and never smokers undergoing general surgical procedures in Veterans Affairs (VA) hospitals; and to determine whether the relationship between smoking and cost is mediated by postoperative complications. Patients undergoing general surgery during the period of October 1, 2005 to September 30, 2006 were identified in the VA Surgical Quality Improvement Program (VASQIP) data set. Inpatient costs were extracted from the VA Decision Support System (DSS). Relative surgical costs (incurred during index hospitalization and within 30 days of operation) for current and former smokers relative to never smokers, and possible mediators of the association between smoking status and cost were estimated using generalized linear regression models. Models were adjusted for preoperative and operative variables, accounting for clustering of costs at the hospital level. Of the 14,853 general surgical patients, 34% were current smokers, 39% were former smokers, and 27% were never smokers. After controlling for patient covariates, current smokers had significantly higher costs compared with never smokers: relative cost was 1.04 (95% Cl 1.00 to 1.07; p = 0.04); relative costs for former smokers did not differ significantly from those of never smokers: 1.02 (95% Cl 0.99 to 1.06; p = 0.14). The relationship between smoking and hospital costs for current smokers was partially mediated by postoperative respiratory complications. These findings complement emerging evidence recommending effective smoking cessation programs in general surgical patients and provide an estimate of the potential savings that could be accrued during the preoperative period.

We aimed to conduct culturally-based participatory research to assess cultural and belief contexts for smoking behaviours within Mandarin and Cantonese communities. Outcome variables were smoking-related knowledge, smoking patterns, attitudes and beliefs, and perceived barriers and facilitators to successful cessation. A community-based approach was applied involving smokers, community key-informants and professionals in study design and implementation. Initially, focus groups were conducted and findings were used to develop study instrument. Participants responded once to study questionnaire after informed consent. Community based in the Greater Vancouver Area, Canada. 16 Chinese smokers participated in focus groups and subsequently, 167 current Chinese immigrant (137 males and 30 females) smokers from Mandarin and Cantonese communities, recruited with the help of community agencies and collaborating physicians, were enrolled in a cross-sectional study. We found that a majority believed smoking was harmful on their health. Younger smokers (<35 years of age) did not mind smoking in front of young children compared to older smokers (≥35 years of age) (p<0.001). People with high school or lower levels of education believed that they would benefit more from smoking than suffering from withdrawal symptoms compared to better educated smokers (p<0.05). Mandarin smokers were significantly more likely to encourage others to quit than Cantonese smokers (p<0.05). Many indicated not receiving adequate support from care providers and lack of access to culturally and linguistically appropriate cessation programmes impacted on their ability to quit smoking. Our study highlighted the importance of tobacco beliefs and perceptions among Mandarin and Cantonese speaking immigrants with limited access to healthcare information and for younger smokers whose attention to health consequences of smoking may be limited as well. Study participants were generally aware of the health risks and were willing to quit. Access to appropriate cessation programmes would fulfil their willingness.

We investigated how volumes of cerebrospinal fluid (CSF), grey matter (GM) and white matter (WM) varied with age, sex, small vessel disease and cardiovascular risk factors in the Rotterdam Scan Study. Participants (n=490; 60-90 years) were non-demented and 51.0% had hypertension, 4.9% had diabetes mellitus, 17.8% were current smoker and 54.0% were former smoker. We segmented brain MR-images into GM, normal WM, white matter lesion (WML) and CSF. Brain infarcts were rated visually. Volumes were expressed as percentage of intra-cranial volume. With increasing age, volumes of total brain, normal WM and total WM decreased; that of GM remained unchanged; and that of WML increased, in both men and women. Excluding persons with infarcts did not alter these results. Persons with larger load of small vessel disease had smaller brain volume, especially normal WM volume. Diastolic blood pressure, diabetes mellitus and current smoking were also related to smaller brain volume. In the elderly, higher age, small vessel disease and cardiovascular risk factors are associated with smaller brain volume, especially WM volume.

Background Cigarette smoking remains a leading cause of morbidity and mortality. Although gender differences in cigarette smoking in the U.S. population have been documented, information on these differences among working adults is limited. Purpose To describe the current smoking prevalence by gender among working U.S. adults and examine gender differences in smoking by occupation. Methods The 2004–2011 National Health Interview Survey data for adults aged ≥18 years that were working in the week prior to the interview (N=132,215) were analyzed in 2013. Current cigarette smokers were those who smoked at least 100 cigarettes in their lifetime and currently smoke every day or some days. Results During 2004–2011, an estimated 22.8% of men workers and 18.3% of women workers were current smokers. Of the current smokers, women workers had higher odds of being an everyday smoker (prevalence OR [POR]=1.17, 95% CI=1.09, 1.26); having poor self-rated emotional health (POR=1.28, 95% CI=1.15, 1.41); and having chronic obstructive pulmonary disease (POR=2.45, 95% CI=2.14, 2.80), heart disease (POR=1.27, 95% CI=1.12, 1.45), and current asthma (POR=2.21, 95% CI=1.96, 2.49) compared with men workers. Women in “supervisors, construction, and extraction” (38.9%) occupations and men in “extraction” (40.5%) occupations had the highest smoking prevalence. Conclusion Among working adults, women had lower prevalence of smoking than men, yet women who smoke were more likely than men to have adverse health outcomes, including self-rated poorer physical and emotional health.

The US Preventive Services Task Force (USPSTF) recommends computed tomography (CT) lung cancer screening for ever-smokers aged 55 to 80 years who have smoked at least 30 pack-years with no more than 15 years since quitting. However, selecting ever-smokers for screening using individualized lung cancer risk calculations may be more effective and efficient than current USPSTF recommendations. Comparison of modeled outcomes from risk-based CT lung-screening strategies vs USPSTF recommendations. Empirical risk models for lung cancer incidence and death in the absence of CT screening using data on ever-smokers from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO; 1993-2009) control group. Covariates included age; education; sex; race; smoking intensity, duration, and quit-years; body mass index; family history of lung cancer; and self-reported emphysema. Model validation in the chest radiography groups of the PLCO and the National Lung Screening Trial (NLST; 2002-2009), with additional validation of the death model in the National Health Interview Survey (NHIS; 1997-2001), a representative sample of the United States. Models were applied to US ever-smokers aged 50 to 80 years (NHIS 2010-2012) to estimate outcomes of risk-based selection for CT lung screening, assuming screening for all ever-smokers, yield the percent changes in lung cancer detection and death observed in the NLST. Annual CT lung screening for 3 years beginning at age 50 years. For model validity: calibration (number of model-predicted cases divided by number of observed cases [estimated/observed]) and discrimination (area under curve [AUC]). For modeled screening outcomes: estimated number of screen-avertable lung cancer deaths and estimated screening effectiveness (number needed to screen [NNS] to prevent 1 lung cancer death). Lung cancer incidence and death risk models were well calibrated in PLCO and NLST. The lung cancer death model calibrated and discriminated well for US ever-smokers aged 50 to 80 years (NHIS 1997-2001: estimated/observed = 0.94 [95%CI, 0.84-1.05]; AUC, 0.78 [95%CI, 0.76-0.80]). Under USPSTF recommendations, the models estimated 9.0 million US ever-smokers would qualify for lung cancer screening and 46,488 (95% CI, 43,924-49,053) lung cancer deaths were estimated as screen-avertable over 5 years (estimated NNS, 194 [95% CI, 187-201]). In contrast, risk-based selection screening of the same number of ever-smokers (9.0 million) at highest 5-year lung cancer risk (≥1.9%) was estimated to avert 20% more deaths (55,717 [95% CI, 53,033-58,400]) and was estimated to reduce the estimated NNS by 17% (NNS, 162 [95% CI, 157-166]). Among a cohort of US ever-smokers aged 50 to 80 years, application of a risk-based model for CT screening for lung cancer compared with a model based on USPSTF recommendations was estimated to be associated with a greater number of lung cancer deaths prevented over 5 years, along with a lower NNS to prevent 1 lung cancer death.

Tobacco demand (i.e., relative value attributed to a given reinforcer) and delay discounting (i.e., relative preference for smaller immediate rewards over larger delayed rewards) are two behavioral economic processes that are linked to the progression of problematic substance use. These processes have not been studied among those with psychopathology, a vulnerable group of smokers. The current study examined differences in tobacco demand and delay discounting, and their association with smoking topography among smokers with (n=43) and without (n=64) past-year psychopathology. Adult daily smokers (n=107,M age =43.5; SD=9.7) participated in a study on "smoking behavior." Past-year psychological disorders were assessed via a clinician-administered diagnostic assessment. All subjects participated in an ad libitum smoking trial and then completed an assessment of delay discounting (Monetary Choice Questionnaire) and tobacco demand (Cigarette Purchase Task) approximately 45-60min post-smoking. Smokers with psychopathology, compared to those without, had significantly higher demand intensity and maximum expenditure on tobacco (O max ), but did not differ on other demand indices or delay discounting. Smokers with psychopathology had shorter average inter-puff intervals and shorter time to cigarette completion than smokers without psychopathology. Tobacco demand and delay discounting measures were significantly intercorrelated among smokers with psychopathology, but not those without. Both behavioral economic measures were associated with specific aspects of smoking topography in smokers with psychopathology. The association between tobacco demand and delay discounting is evident among smokers with psychopathology and both measures were most consistently related to smoking behavior.

In women, cardiac deaths attributable to tobacco exposure have reached the same high levels as men. Normally, sympathetic nerve activity (SNA) fluctuates according to the menstrual phase, but in habitual smokers, SNA levels remain constant. Our purpose is to extend these observations to other groups of women exposed to tobacco smoke and to explore potential mechanisms. We hypothesize that women exposed to secondhand smoke, but not former smokers, have nonfluctuating SNA compared with never smokers, and that impaired baroreflex suppression of SNA, and/or heightened central SNA responses, underlie this nonfluctuating SNA. We also hypothesize that female smokers have impaired nocturnal blood pressure dipping, normally mediated by modulation of SNA. In 49 females (19 never, 12 current, 9 former, 9 passive smokers), SNA was recorded (microneurography) during high- and low-hormone ovarian phases at rest, during pharmacological baroreflex testing, and during the cold pressor test (CPT). Twenty-four hour blood pressure (BP) monitoring was performed. Current and passive smokers, but not former smokers, had a nonfluctuating pattern of SNA, unlike never smokers in whom SNA varied with the menstrual phase. Baroreflex control of SNA was significantly blunted in current smokers, independent of menstrual phase. In passive smokers, SNA response to CPT was markedly increased. Nondipping was unexpectedly high in all groups. SNA does not vary during the menstrual cycle in active and passive smokers, unlike never and former smokers. Baroreflex control of SNA is blunted in current smokers, whereas SNA response to CPT is heightened in passive smokers. Smoking cessation is associated with return of the altered SNA pattern to normal.

There is little published about the role of individual characteristics in occupational injuries. Construction workers have a high rate of injury; we assessed 11 personal characteristics in this professional sector. A case-control study was conducted on 880 male workers who had had at least one occupational injury during a 2-year period and 880 controls. A questionnaire was administered by an occupational physician. Statistical analysis was made via logistic regression method. Young age (<30 years), sleep disorders and current smoker influenced all the injuries combined. Sleep disorders and young age were common risk factors for several jobs. Physical disabilities and no sporting activity had a role in masons, and 5 years or less in present job in plumbers and electricians only. Sleep disorders influenced both the injuries with and without hospitalization; young age, current smoker, and physical disability influenced those without hospitalization only. Young age, sleep disorders, smoking, disabilities, sporting activity, and experience influenced the occupational injuries. The risk for each worker depended on his job. Occupational physicians could inform the workers of these risks and encourage them to take remedial action. Copyright 2003 Wiley-Liss, Inc.

Cannabis is the most widely consumed illicit drug worldwide and the relation between cannabis smoking and lung cancer is suggestive, albeit inconclusive. We conducted three hospital based case-control studies in Tunisia, Morocco, and Algeria, three areas of high prevalence of cannabis consumption as well as production. This paper presents the pooled analysis of these three studies restricted to men with a total of 430 cases and 778 controls. Ninety-six percent of the cases and 67.8% of the controls were tobacco smokers and 15.3% of the cases and 5% of the controls were ever cannabis smokers. All cannabis smokers were tobacco users. Adjusting for country, age, tobacco smoking, and occupational exposure, the odds ratio (OR) for lung cancer was 2.4 (95% confidence interval [CI]: 1.6-3.8) for ever cannabis smoking. This association remained after adjustment for lifetime tobacco packyears as continuous variable, OR = 2.3 (95% CI: 1.5-3.6). The OR adjusted for intensity of tobacco smoking (cigarette/d) among current tobacco smokers and never cannabis smokers was 10.9 (95% CI: 6.0-19.7) and the OR among current tobacco users and ever cannabis smokers was 18.2 (95% CI: 8.0-41.0). The risk of lung cancer increased with increasing joint-years, but not with increasing dose or duration of cannabis smoking. Our results suggest that cannabis smoking may be a risk factor for lung cancer. However, residual confounding by tobacco smoking or other potential confounders may explain part of the increased risk.

Evidence suggests that consumers correctly identify nicotine as addictive; however, many may also harbor misconceptions about its harmfulness. The majority of this evidence is based on survey data, however, which may be prone to some limitations. In the current study, we employed qualitative methods to examine, in their own words, smokers' beliefs about nicotine and addiction. Twelve 1-hr focus groups were conducted in 3 cities in the United States (Columbus, OH; New Orleans, LA; and Washington, DC) from October to November, 2014. Adult cigarette smokers (N = 108), defined as those who reported smoking cigarettes on every day or some days, were segmented by age group (18-25 years and ≥26 years) and tobacco-use behavior. Thematic, in-depth analysis of focus-group discussion transcripts was conducted. Participant demographic information was recorded. Results showed that smokers identify nicotine as a cause of addiction to cigarettes; however, they also attribute their addiction to other factors. When asked about nicotine's effects on the body, immediate physiological effects of smoking (e.g., stimulation, relaxation) were top of mind. Opinions varied in terms of whether nicotine itself was harmful or harmless; many were unsure and/or had not considered this question. Discussions revealed heterogeneity in smokers' beliefs as well as recognition of their own uncertainty and lack of knowledge. The current findings provide insight that smokers may not be as misinformed regarding the relative harms of nicotine and tobacco, as has been suggested by quantitative evidence. Implications for future research are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).
Impact of a board-game approach on current smokers: a randomized controlled trial
2013-01-01
Background The main objective of our study was to assess the impact of a board game on smoking status and smoking-related variables in current smokers. To accomplish this objective, we conducted a randomized controlled trial comparing the game group with a psychoeducation group and a waiting-list control group. Methods The following measures were performed at participant inclusion, as well as after a 2-week and a 3-month follow-up period: “Attitudes Towards Smoking Scale” (ATS-18), “Smoking Self-Efficacy Questionnaire” (SEQ-12), “Attitudes Towards Nicotine Replacement Therapy” scale (ANRT-12), number of cigarettes smoked per day, stages of change, quit attempts, and smoking status. Furthermore, participants were assessed for concurrent psychiatric disorders and for the severity of nicotine dependence with the Fagerström Test for Nicotine Dependence (FTND). Results A time × group effect was observed for subscales of the ANRT-12, ATS-18 and SEQ-12, as well as for the number of cigarettes smoked per day. At three months follow-up, compared to the participants allocated to the waiting list group, those on Pick-Klop group were less likely to remain smoker. Outcomes at 3 months were not predicted by gender, age, FTND, stage of change, or psychiatric disorders at inclusion. Conclusions The board game seems to be a good option for smokers. The game led to improvements in variables known to predict quitting in smokers. Furthermore, it increased smoking-cessation rates at 3-months follow-up. The game is also an interesting alternative for smokers in the precontemplation stage. PMID:23327643

Cigarette smoking is the leading preventable cause of death and disease in Canada, and is disproportionately more frequent among psychiatric patients. Smoking cessation interventions can be successfully implemented with psychiatric patients, yet no Canadian studies have evaluated smoking prevalence, nicotine dependence, and motivation for smoking cessation in psychiatric inpatients. Our study did so to help plan appropriate interventions for these patients. All inpatients aged 18 years or older admitted to acute-care psychiatry units at the Foothills Medical Centre in Calgary, Alberta, during a 6-month period completed a survey involving questions from the Canadian Tobacco Use Monitoring Survey, the Fagerstrom Test for Nicotine Dependence (FTND), the Readiness to Quit Ladder, and the Decisional Balance for Cigarette Smoking. Responses were analyzed for correlation with discharge diagnoses, age, and sex. Among the total inpatients (n = 342), 211 (62%) completed the survey. Among those, 55% were current cigarette smokers and 17.5% were former smokers. Nicotine dependence (FTND > or = 6) was reported in 45.2% of smokers. Smoking prevalence and nicotine dependence severity was greatest in the substance use disorders (SUD) and psychotic disorders groups. Current smokers endorsed more negative than positive attributes of smoking. Regarding smoking cessation, 51% of patients were precontemplative, 12.7% contemplative, and 36.2% preparatory or action-oriented, despite few receiving advice to quit. Cigarette smoking and nicotine dependence are highly prevalent in psychiatric inpatients. However, self-reported motivation for smoking cessation is noteworthy, emphasizing that cessation advice and appropriate follow-up care should be provided to psychiatric inpatients who smoke.

Paramedical personnel are exposed to tobacco smoking. Electronic cigarettes (e-cigarettes) may be considered as a lower-risk substitute for cigarettes. The aim of the study was to estimate the prevalence of e-cigarette use, the motives for use and the perceptions among French military nurses. A cross-sectional survey, using self-administered questionnaires, was conducted in 2013 among 300 students and instructors of the French school of military paramedical personnel. Prevalences of e-cigarette use among smokers and nonsmokers were compared using logistic regressions adjusted on age and gender. The prevalence of smoking was 40% among the 200 responders. E-cigarette current use prevalence was 25% (6% daily users), without significant difference according to gender and age. Tobacco smokers reported significantly more e-cigarette current use (51% vs7%). Motives for e-cigarette use reported by smokers were curiosity (48%), intention to reduce tobacco consumption (43%) or to quit smoking (8%). Among users of both tobacco and e-cigarettes, 48% reported a significant decrease in tobacco consumption following e-cigarette initiation (average decrease of 5-10 cigarettes smoked per day; p <0.001). Both tobacco smokers and nonsmokers (88%) estimated that e-cigarette use was potentially harmful for health, but it was perceived as less harmful than tobacco by 46%. E-cigarette use among military nurses follows the trends observed in the general population in terms of prevalence and motives. E-cigarettes, which are seen as an attractive alternative to cigarettes, may contribute to a reduction in tobacco use among healthcare workers.

Objective Smoking is common in patients with allergic diseases. The aim of this study was to evaluate the cross-sectional association between the current smoking status and total and specific Immunoglobulin E (IgE) levels in Korean adults. Methods Data were obtained from the 2010 Korean National Health and Nutrition Examination Survey, a national cross-sectional study. We analyzed the data of subjects whose smoking status and serum IgE levels were of acceptable quality. Results A total of 1,963 subjects (1,118 never smokers, 340 ex-smokers, and 505 current smokers) were included. The total IgE levels and specific IgE levels to house dust mite Dermatophagoides farinae (Df), cockroach, and dog allergens in never smokers were significantly (p<0.0001) lower than in ex-smokers or current smokers. After adjusting for other variables, current smokers independently had significantly higher levels of total IgE and cockroach-specific IgE than ex-smokers or never smokers. The proportions of subjects with total IgE ≥150 kU/L and specific IgE ≥0.35 kU/L to Df-specific IgE were significantly (p value for trend <0.05) increased in ex-smokers and current smokers. The total IgE levels and IgE levels specific to Df, cockroaches, and dogs significantly (p value for trend <0.05) and proportionally increased with increasing numbers of cigarettes smoked daily. Conclusion Smoking was associated with elevated total IgE levels and IgE levels specific to Df, cockroach, and dog allergens in a cumulative, dose-dependent manner. Furthermore, current smoking status was an independent risk factor for elevated total IgE levels and IgE levels specific to cockroach allergen.

This study was designed to investigate how young men and women smokers and non-smokers talk about the impact of smoking on appearance, with the aim of using these accounts to inform anti-smoking campaigns targeted at young people. Volunteer smokers and non-smokers took part in 24 focus groups. Eighty-seven men and women aged 17-24 were asked to talk about impacts of smoking on appearance. A thematic analysis of transcripts suggested that weight gain after quitting was only a significant concern for the younger (17-year-old) women. Non-smokers of both genders expressed concern about yellowing of skin and teeth if they started smoking, and women non-smokers were concerned about skin ageing. Smokers believed that smoking made them look 'cool', mature, and sophisticated and would quit only if skin ageing and other negative effects on appearance became visible. Appearance concerns are relevant to the decision whether to start and quit smoking, and are linked to gender and age. Results are discussed in relation to implications for the development of age- and gender-relevant anti-smoking interventions.

Issue addressed Tobacco consumption contributes to health disparities among Aboriginal Australians who experience a greater burden of smoking-related death and diseases. This paper reports findings from a baseline survey on factors associated with smoking, cessation behaviours and attitudes towards smoke-free homes among the Aboriginal population in inner and south-western Sydney. Methods A baseline survey was conducted in inner and south-western Sydney from October 2010 to July 2011. The survey applied both interviewer-administered and self-administered data collection methods. Multiple logistic regression was performed to determine the factors associated with smoking. Results Six hundred and sixty-three participants completed the survey. The majority were female (67.5%), below the age of 50 (66.6%) and more than half were employed (54.7%). Almost half were current smokers (48.4%) with the majority intending to quit in the next 6 months (79.0%) and living in a smoke-free home (70.4%). Those aged 30-39 years (AOR 3.28; 95% CI: 2.06-5.23) and the unemployed (AOR 1.67; 95% CI: 1.11-2.51) had higher odds for current smoking. Participants who had a more positive attitude towards smoke-free homes were less likely to smoke (AOR 0.79; 95% CI: 0.74-.85). Conclusions A high proportion of participants were current smokers among whom intention to quit was high. Age, work status and attitudes towards smoke-free home were factors associated with smoking. So what? The findings address the scarcity of local evidence crucial for promoting cessation among Aboriginal tobacco smokers. Targeted promotions for socio-demographic subgroups and of attitudes towards smoke-free homes could be meaningful strategies for future smoking-cessation initiatives.

Tobacco use among youth is a major public health problem. Youth outside of formal school settings are often understudied but may be at increased risk. A descriptive cross- sectional study was carried out among 326 young people aged 15-24 years in four randomly selected motor parks in Lagos state. Interviewer-administered questionnaires were used to collect data. The mean age of the respondents was 21.0±2.3yrs. Many 252 (77.3%) dropped out before the end of the third year of secondary schooling. The majority were aware that active (78.2%), and passive smoking (77.3%) are harmful to health. Nearly two-thirds of the respondents disagreed with an outright ban of cigarettes (63.2%) and restriction of cigarette sales to persons below 18 years (67.9%) while 254 (66.8%) supported a ban on tobacco smoking in enclosed public places. One hundred and fifty (46.0%) respondents had experimented with smoking of which 106 (32.5%) had progressed to become current smokers. Half of the current smokers, 54 (50.9%), felt the need for a cigarette first thing in the morning. A multivariate analysis for smoking initiation, showed that for every increasing year of age, respondents were 1.08 times more likely to have initiated cigarette smoking; males and respondents who lived alone or with peers were 2.34 times and 1.77 times more likely to have initiated smoking respectively; those who consume alcohol and marijuana were 7.27 and 1.89 times respectively more likely to have initiated smoking while those who consumed alcohol were 6.17 times more likely to be current smokers.

To identify sociodemographic characteristics associated with having tried a potentialy reduced-exposure tobacco product (PREP) and to compare the smoking and quitting behaviors and attitudes of smokers who have tried a PREP product with non-PREP users. Analysis is based on a sample of 43,419 current and recent former smokers from the 2003 Tobacco Use Supplement to the Current Population Survey. Overall, PREP use is low (2.5%). Current daily and someday only smokers have higher rates of use (2.9% and 2.4%, respectively) compared with former smokers (1.5%). PREP use is higher in southern states and among younger smokers, non-Hispanic Whites, and those with some college education. Smokers who have tried a PREP product are more likely to smoke light or ultra-light cigarettes, report more symptoms of nicotine dependence, smoke more cigarettes per day, report a higher number of quit attempts, and seek quitting assistance from pharmacotherapy and behavioral therapies compared with non-PREP users. These findings support the concern that current smokers who are highly dependent yet motivated to quit smoking may seek PREPs as an alternative strategy to smoking cessation.

BACKGROUND Although data clearly link major depression and smoking, little is known about the association between dysthymia and minor depression and smoking behavior. The current study examined changes in smoking over three years for current and former smokers with and without dysthymia and minor depression. METHODS Participants who were current or former daily cigarette smokers at Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions and completed the Wave 2 assessment were included in these analyses (n=11,973; 46% female). Analyses examined the main and gender-specific effects of current dysthymia, lifetime dysthymia, and minor depression (a single diagnostic category that denoted current and or lifetime prevalence) on continued smoking for Wave 1 current daily smokers and continued abstinence for Wave 1 former daily smokers. RESULTS Wave 1 current daily smokers with current dysthymia (OR=2.13, 95% CI=1.23, 3.70) or minor depression (OR=1.53, 95% CI=1.07, 2.18) were more likely than smokers without the respective diagnosis to report continued smoking at Wave 2. Wave 1 former daily smokers with current dysthymia (OR=0.44, 95% CI=0.20, 0.96) and lifetime dysthymia (OR=0.37, 95% CI=0.15, 0.91) were less likely than those without the diagnosis to remain abstinent from smoking at Wave 2. The gender-by-diagnosis interactions were not significant, suggesting that the impact of dysthymia and minor depression on smoking behavior is similar among men and women. CONCLUSIONS Current dysthymia and minor depression are associated with a greater likelihood of continued smoking; current and lifetime dysthymia are associated with a decreased likelihood of continued smoking abstinence.

Cigarette smokers have their own motivation and justification to smoke. For example, smoking reduces their stress or enhances their pleasure. This study aimed to identify the (a) prevalence of cigarette smokers among undergraduates in Malaysia, (b) gender differences in nicotine dependence among current smokers, (c) differences in psychological problems (depression, anxiety and stress) based on the status of smoking cigarettes (current, former and non-smokers) and (d) extent to which precipitating factors (tension reduction, addiction, automatism, handling, social interaction, pleasure, and stimulation) predict the smoking behavior among current smokers. In this study 780 undergraduate students participated from a private university in Kuala Lumpur and Selangor state in Malaysia. The Depression, Stress and Anxiety Scale, Modified Reason for Smoking Scale and Fagerstrom Nicotine Dependence Test were used to measure psychological problems, predictors of smoking behavior and nicotine dependency among current smokers. The results showed that 14.7%(n=106) of the students were smokers. Current smokers exhibited more psychological problems (depression, anxiety and stress) compared to former and non-smokers. Addiction, tension reduction, pleasure and automatism were predictors of smoking behavior among the current smoking students. Step wise regression analysis showed that smoking behavior was highly predicted by nicotine dependency or addiction. Smoking students were motivated to smoke cigarettes as they believed that it reduced their tension and enhance pleasure. Hence, there is a need for health promotion and anti-tobacco prevention as cigarette smokers experience more psychological problems. Nicotine dependency or addition was one of the major causes for smoking behavior among the student population in Malaysia.

To estimate smoking prevalence by gender, describe patterns of cigarette use, and identify predictors of current smoking in reproductive-age adults in four Latin American countries. Self-reported smoking was examined using data from Reproductive Health Surveys of women aged 15-49 years in Ecuador (2004), El Salvador (2002-2003), Guatemala (2002), and Honduras (2001), and of men aged 15-59 years in El Salvador, Guatemala, and Honduras for the same years. Current smoking was assessed by demographic characteristics, and independent associations were examined using logistic regression. Data were weighted to be nationally representative of households with reproductive-age women and men. Current smoking prevalence ranged from 2.6% (Guatemala) to 13.1% (Ecuador) for women and from 23.1% (Guatemala) to 34.9% (El Salvador) for men. In Ecuador, 67.6% of female smokers were non-daily users; in other countries, daily use was more prevalent than non-daily use for both men and women. In daily users, the median number of cigarettes smoked per day ranged from 1.9 (Ecuador, Honduras) to 2.3 (Guatemala) for women and from 2.1 (Guatemala) to 3.6 (Honduras) for men. In bivariate analysis, smoking prevalence in all countries was highest in women who lived in urban areas, were previously married, and/or had high socioeconomic status. Risk factors for smoking varied by country and gender. National tobacco control programs in these countries should aggressively target high-risk populations (reproductive-age men) and maintain low prevalence in low-risk populations (reproductive-age women). More research is needed to understand addiction patterns in non-daily smokers.

While risk factors of osteoporosis in Western populations have been extensively documented, such a profile has not been well studied in Caucasians of non-European origin. This study was designed to estimate the modifiable distribution and determinants of bone mineral density (BMD) among Iranian women in Australia. Ninety women aged 35 years and older completed a questionnaire on socio-demographic and lifestyle factors. BMD was measured at the lumbar spine (LS) and femoral neck (FN) using DXA (GE Lunar, WI, USA), and was expressed in g/cm2 as well as T-score. In multiple regression analysis, advancing age, lower body mass index (BMI), and smoking were independently associated with LS and FN BMD, with the 3 factors collectively accounting for 30% and 38% variance of LS and FN BMD, respectively. LS and FN BMD in smokers was 8% lower than that in non-smokers. Further analysis of interaction between BMI and smoking revealed that the effect of smoking was only observed in the obese group (p = 0.029 for LSBMD and p = 0.007 for FNBMD), but not in the overweight and normal groups. Using T-scores from two bone sites the prevalence of osteoporosis (T-scores

To study the effect of smoking, passive smoking, alcohol drinking, and occupational exposure to low level of benzene on DNA strand breaks in elevator manufacturing workers in Guangzhou, China. Three hundred and fifty-nine workers (252 men and 107 women) of a modern elevator manufacturing factory, 205 were from production departments and 154 from managerial department. Information on the workers' health conditions, smoking, passive smoking, alcohol consumption and occupational exposure history was collected by personal interview. Lymphocyte DNA damage was measured by the Comet assay. None of the women smoked and 20.6% of the men were daily smokers. In non-smokers, the prevalence of passive smoking at work was 25% for men and 11.2% for women, and at home, 37.8 and 48.6%, respectively. Smoking significantly increased tail moment (P<0.001). Daily smokers had the largest tail moment (geometric mean, 95% CI) (0.93 microm (0.81-0.94)), followed by occasional smokers (0.76 microm (0.59-0.95)), ex-smokers (0.70 microm (0.58-0.85)), and never smokers (0.56 microm (0.53-0.60)). Tail moment increased significantly with daily tobacco consumption (cigarettes per day) (r=0.26, P<0.001) after adjusting for age, gender, occupational exposure, passive smoking, and drinking. Analysis of covariance (ANCOVA) showed that smoking (P<0.001), passive smoking at home (P=0.026), occupational exposure (P<0.001), male gender (P<0.001), and age (P=0.001) had independent effects on tail moment, whereas passive smoking at work and alcohol drinking had no significant effect. Smoking, passive smoking at home, male gender, age and occupational exposure independently increased lymphocyte DNA strand breaks. The presence of excess DNA damage under low level of occupational exposure to benzene or other solvents suggest that the current allowance concentrations may not be safe to prevent genotoxicity.

Tobacco use during adolescence is a substantial problem and adolescents are at higher risk of addiction and prolonged use. To reduce the burden of tobacco-related morbidity and mortality, monitoring of adolescent tobacco use is imperative. We aimed to determine the prevalence of tobacco use among adolescents in urban and rural secondary schools in Enugu State, southeast Nigeria. A cross-sectional study of 4332 adolescents in 8th to 10th grades in 25 urban and 24 rural secondary schools in Enugu, Nigeria was done using Global Youth Tobacco Survey (GYTS) methodology. Students were asked about previous and current tobacco use, smoking cessation, and susceptibility to smoking initiation among non-smokers. Geographical, age and sex prevalence differences were examined. Analyses were performed for all adolescents (10-19 years) and for a subset of students, 13-15 years of age for comparison with previous GYTS surveys. All analyses were weighted to account for the complex survey design and for differential non-response at school, class and student levels. About 28.9% of students reported ever smoking cigarettes; 19.4% reported current tobacco use among all adolescents (13.3, 5.8 and 7.8% for cigarettes, other smoked tobacco, and smokeless tobacco, respectively) while 18.6% reported current tobacco use among 13-15 year olds (12.6, 5.2 and 7.5% for cigarettes, other smoked tobacco and smokeless tobacco respectively). Prevalence of all types of tobacco use was higher in rural schools (vs. urban schools), and among boys (vs. girls). Susceptibility to smoking initiation among non-smokers was 9.3% (95% CI: 8.1-10.7) among all adolescents, and 9% (95% CI: 7.6-10.7) among 13-15 year olds. About 88.1% of all adolescent smokers desired to quit and 57.9% of them had never received help to quit smoking. Nearly one in every five school-going adolescents currently uses at least one type of tobacco in Enugu State, southeast Nigeria. Prevalence of tobacco use is higher in rural schools and among boys in this setting. Most adolescent current smokers desire to quit and need smoking cessation support.

Smokers often have oral health problems. We studied whether poor oral health among non-smoking adolescents is connected to smoking behaviour in adulthood. We used an age cohort born in 1979 (n = 2582) taking part in annual oral health check-ups between the ages of 13 and 15. Self-reported non-smokers were used as the study population. As measures we used decayed, missing or filled teeth/surfaces (DMF) and decayed teeth (D) and smoking behaviour at ages 13-15 and the depending measure was smoking behaviour at the age of 29. Those who were non-smokers at ages 13-15 and had tooth decay (D > 0) in an oral check-up during that period had higher risk (OR (Odds Ratio) 1.88, 95% confidence interval 1.2-2.9) of being a smoker by age 29. Tooth decay at age 15 predicted earlier onset of smoking for those, who became smokers later in life. Dental caries (DMF > 0) was not associated with higher risk of becoming a smoking adult, but those with dental caries at age 13 were more likely to start smoking earlier. Poorer dental health, especially tooth decay in adolescence is a possible indicator of a greater likelihood of transforming from being a non-smoker to a smoker. Dentists should notice this for allocated health promotion. © The Author 2014. Published by Oxford University Press on behalf of the European Public Health Association. All rights reserved.

Differences in patient characteristics and outcomes have been observed among current, former, and never-smokers with lung cancer, but most prior studies included few never-smokers and were not prospective. We used data from a large, prospective study of lung cancer care and outcomes in the United States to compare characteristics of never-smokers and smokers with lung cancer and to examine survival among the never-smokers. Smoking status at diagnosis was determined by self-report and survival was determined from medical records and cancer registries, with follow-up through June 2010 or later. Cox regression was used to examine the association between smoking and survival, and to identify predictors of survival among never-smokers. Among 3,410 patients with lung cancer diagnosed between September 1, 2003 and October 14, 2005 who completed a baseline patient survey, there were 274 never-smokers (8%), 1,612 former smokers (47%), 1,496 current smokers or smokers who quit recently (44%), and 28 with missing information about smoking status (<1%). Never-smokers appeared more likely than former and current/recent smokers to be female and of Asian or Hispanic race/ethnicity, and to have adenocarcinoma histology, fewer comorbidities, private insurance, and higher income and education. Compared with never-smokers, the adjusted hazard of death from any cause was 29% higher among former smokers (hazard ratio, 1.29; 95% confidence interval, 1.08-1.55), and 39% higher among current/recent smokers (hazard ratio, 1.39; 95% confidence interval, 1.16-1.67). Factors predicting worse overall survival among never-smokers included Hispanic ethnicity, severe comorbidity, undifferentiated histology, and regional or distant stage. Never-smoking Hispanics appeared more likely to have regional or advanced disease at diagnosis and less likely to undergo surgical resection, although these differences were not statistically significant. Never-smokers with lung cancer are more likely than ever-smokers to be female, Asian or Hispanic, and more advantaged socioeconomically, suggesting possible etiologic differences in lung cancer by smoking status. Among never-smokers, Hispanics with lung cancer had worse survival than non-Hispanic whites.

Objective: To explore the relationship between smoking and hyperuricemia in Chinese residents. Methods: Based on data from the China Health and Nutrition Survey (CHNS), residents with blood samples provided in the 2009 round (including information of socio-demographic factors, lifestyle behaviors, medical history, and laboratory examinations etc.) were selected as the participants in the current analysis. Unconditional logistic regression models were utilized to compute the ORs and corresponding 95% CIs for assessing the relationship between smoking and hyperuricemia. Results: Among the 8 785 subjects, 1 435 had hyperuricemia with a prevalence rate of 16.3%, consisting of 886 men and 549 women with prevalence rates of 21.6% (886/4 110) and 11.7% (549/4 675) , respectively. Compared with never smokers, the adjusted OR (95% CI ) for hyperuricemia was 0.83 (0.70-0.98) among current smokers, 0.77 (0.63-0.94) among current smokers with 20-39 years of smoking, and 0.79 (0.65-0.97) among current smokers with 11-20 cigarettes per day. When stratified by gender and compared with non-smoker, the adjusted OR (95% CI ) for hyperuricemia among current smokers compared with never smokers was 0.83 (0.70-0.98) among men, while no significant association was found in female current smokers ( OR= 0.73, 95% CI: 0.42-1.26, P= 0.260). Conclusion: In Chinese residents, there is an inverse association between smoking and hyperuricemia prevalence, and this association may be related to duration and intensity of smoking among current smokers. The findings need to be validated in large prospective cohort studies.
Youth tobacco surveillance--United States, 2000.
2001-11-02
Tobacco use is the single leading preventable cause of death in the United States, accounting for approximately 430,000 deaths each year. The prevalence of cigarette smoking nationwide among high school students increased during the 1990s, peaking during 1996-1997, then began a gradual decline. Approximately 80% of tobacco users initiate use before age 18 years. If the trend in early initiation of cigarette smoking continues, approximately 5 million children aged <18 years who are living today will die prematurely because they began to smoke cigarettes during adolescence. The economic costs associated with tobacco use ranges from $53 billion to $73 billion per year in medical expenses and $47 billion in lost productivity. Because of these health and economic consequences, CDC has recommended that states establish and maintain comprehensive tobacco-control programs to reduce tobacco use among youth. January 2000 through December 2000. To assist states in developing and maintaining their state-based comprehensive tobacco prevention and control programs, CDC developed the Youth Tobacco Surveillance and Evaluation System, which includes international, national, and state school-based surveys of middle school and high school students. Two components of this system are discussed in this report--the National Youth Tobacco Survey and the state Youth Tobacco Surveys. The national survey is representative of students in the 50 states and the District of Columbia; 35,828 students in 324 schools completed questionnaires in the spring of 2000. Twenty-nine state surveys were conducted in the spring and fall of 2000; state sample sizes ranged from 583 to 33,586 students. This report summarizes data from the 2000 national survey and state surveys. Findings from the National Youth Tobacco Survey indicate that current tobacco use ranges from 15.1% among middle school students to 34.5% among high school students. Cigarette smoking is the most prevalent form of tobacco use, followed by cigar smoking and smokeless tobacco use. Approximately one half of current cigarette smokers in middle school and high school report that they usually smoke Marlboro cigarettes. Black students are more likely to smoke Newport cigarettes than any other brand. More than one half of current cigarette smokers in middle school and high school report that they want to stop smoking. Nearly one fourth of middle school and high school students who have never smoked cigarettes are susceptible to initiating cigarette smoking in the next year. Exposure to secondhand smoke (e.g., environmental tobacco smoke) is substantially higher among both middle school and high school students. During the week before the survey, approximately 9 out of 10 current cigarette smokers and one half of never cigarette smokers were in the same room with someone who was smoking cigarettes; and 8 out of 10 current cigarette smokers and 3 out of 10 never cigarette smokers rode in a car with someone who was smoking cigarettes. Approximately 70% of middle school and 57% of high school students who currently smoke cigarettes live in a home where someone smokes cigarettes. Among never cigarette smokers, approximately 3 out of 10 live in a home where someone smokes cigarettes. Approximately 69% of middle school and 58% of high school students aged <18 years who currently smoke cigarettes were not asked to show proof of age when they bought or tried to buy cigarettes. Approximately 8 out of 10 middle school and high school students have seen antismoking commercials. Eight out of 10 middle school students report having seen actors using tobacco on television or in the movies, and approximately 11% of middle school and 16% of high school students who had never used tobacco would wear or use something with a tobacco company name or picture on it. This rate increases to nearly 60% for current tobacco users. Youth Tobacco Survey data are used by health and education officials to improve national and state programs to prevent and control youth tobacco use. Several states use the data in presentations to their state legislators to demonstrate the need for funding smoking cessation and prevention programs for youth.
Smoking status and psychosocial factors in binge eating disorder and bulimia nervosa.
Chao, Ariana M; White, Marney A; Grilo, Carlos M

To examine eating-disorder psychopathology and depressive symptoms by smoking status (never, former, or current smoker) in persons with binge eating disorder (BED) and bulimia nervosa (BN). Participants were 575 adult volunteers from the community (mean age=36.0±12years and BMI=32.9±9.5kg/m(2); 80% white; 88% female) who were classified with BED (n=410) or BN (n=165). Participants completed a battery of questionnaires, including items about current and historical cigarette smoking, the Eating Disorder Examination -Questionnaire, and the Beck Depression Inventory. Among those with BED, depressive symptoms were significantly higher in current smokers than former or never smokers (p=.001). There were no significant differences in depressive symptoms by smoking status in participants with BN and no differences in eating-disorder psychopathology by smoking status in either the BED or BN groups. In this non-clinical group of community volunteers, we found that smoking history or status was not associated with eating disorder psychopathology in participants classified with BED and BN but was significantly associated with depressive symptoms in participants with BED.

The impact of tobacco use and cessation on atherogenesis remains unclear. We aimed to study the association of tobacco use and prior cessation with the presence, extent and severity of atherosclerosis on coronary computed tomographic angiography (CTA). We examined 1798 consecutive symptomatic patients without known coronary artery disease (CAD) referred for CTA, stratified by smoking status (never, current [within 30 days], or former [>30 days before CTA]). Plaque severity (none, <50%, ≥50% stenosis), composition (non-calcified [NCP], partially calcified [PCP], or calcified plaque [CP]), and segment involvement score (SIS) were visually graded. Multivariate analysis was performed, adjusting for CAD risk factors and cholesterol lowering medication use. The median age of patients was 50 years [IQR:42-58] (61% male), with 74% never smokers, 12% current smokers, and 14% former smokers (median quit duration = 12 years [IQR:3-26]). Smoking exposure in former versus current smokers was 11 [IQR:5-25] and 10 [IQR:2-20] pack-years, respectively (p = 0.01). Compared to never smokers, current smokers demonstrated an increased odds ratio of all plaque types (adjusted OR: any NCP = 1.55 [95% CI 1.04-2.32], p = 0.03; any PCP = 1.61 [1.10-2.37], p = 0.02; any CP = 1.93 [1.32-2.81], p = 0.001), non-obstructive CAD (aOR = 1.47 [1.04, 2.07], p = 0.03), obstructive CAD (aOR = 1.81 [1.01-3.24], p = 0.047), and SIS > 4 (aOR = 1.60 [1.04-2.46], p = 0.03). Compared to current smoking, prior smoking cessation (≥12 years) was associated with a decreased odds ratio of any NCP (aOR = 0.42 [0.19-0.90], p = 0.03), CP (aOR = 0.43 [0.22-0.84], p = 0.02), and obstructive CAD (aOR = 0.40, [0.15-0.98], p = 0.048). Current smoking is independently associated with the presence and extent of coronary plaque, and a higher risk of non-obstructive and obstructive CAD compared to never smoking. Prior smoking cessation correlated with improvements in CTA-identified plaque measures. Published by Elsevier B.V.

To estimate the effect of potential regulations of electronic nicotine delivery systems (ENDS) among adult smokers, including increasing taxes, reducing flavor availability and adding warning labels communicating various levels of risk. We performed a discrete choice experiment (DCE) among a national sample of 1200 adult smokers. We examined heterogeneity in policy responses by age, cigarette quitting interest and current ENDS use. Our experiment overlapped January 2015 by design, providing exogenous variation in cigarette quitting interest from New Year resolutions. KnowledgePanel, an online panel of recruited respondents. A total of 1200 adult smokers from the United States. Hypothetical purchase choice of cigarettes, nicotine replacement therapy and a disposable ENDS. Increasing ENDS prices from $3 to $6 was associated with a 13.6 percentage point reduction in ENDS selection (P < 0.001). Restricting flavor availability in ENDS to tobacco and menthol was associated with a 2.1 percentage point reduction in ENDS selection (P < 0.001). The proposed Food and Drug Administration (FDA) warning label was associated with a 1.1 percentage point reduction in ENDS selection (P < 0.05) and the MarkTen warning label with a 5.1 percentage point reduction (P < 0.001). We estimated an ENDS price elasticity of -1.8 (P < 0.001) among adult smokers. Statistically significant interaction terms (P < 0.001) imply that price responsiveness was higher among adult smokers 18-24 years of age, smokers who have vaped over the last month and smokers with above the median quitting interest. Young adult smokers were 3.7 percentage points more likely to choose ENDS when multiple flavors were available than older adults (P < 0.001). Young adult smokers and those with above the median cigarette quitting interest were also more likely to reduce cigarette selection and increase ENDS selection in January 2015 (P < 0.001), potentially in response to New Year's resolutions to quit smoking. Increased taxes, a proposed US Food and Drug Administration warning label for electronic nicotine delivery systems and a more severe warning label may discourage adult smokers from switching to electronic nicotine delivery systems. Reducing the availability of flavors may reduce ENDS use by young adult smokers. © 2015 Society for the Study of Addiction.

Parent and child cigarette use: a longitudinal, multigenerational study.
Vuolo, Mike; Staff, Jeremy
2013-09-01
Using longitudinal data from the multigenerational Youth Development Study (YDS), this article documents how parents' long-term smoking trajectories are associated with adolescent children's likelihood of smoking. Prospective data from the parents (from age 14-38 years) enable unique comparisons of the parents' and children's smoking behavior, as well as that of siblings. Smoking trajectories are constructed using latent class analysis for the original YDS cohort (n = 1010). Multigenerational longitudinal data from 214 parents and 314 offspring ages 11 years and older are then analyzed by using logistic regression with cluster-corrected SEs. Four latent smoking trajectories emerged among the original cohort: stable nonsmokers (54%), early-onset light smokers who quit/reduce (16%), late-onset persistent smokers (14%), and early-onset persistent heavy smokers (16%). Although 8% of children of stable nonsmokers smoked in the last year, the other groups' children had much higher percentages, ranging from 23% to 29%. Multivariate logistic regression models confirm that these significant differences were robust to the inclusion of myriad child- and parent-level measures (for which child age and grade point average [GPA] are significant predictors). Older sibling smoking, however, mediated the link between parental heavy smoking and child smoking. Even in an era of declining rates of teenage cigarette use in the United States, children of current and former smokers face an elevated risk of smoking. Prevention efforts to weaken intergenerational associations should consider parents' long-term cigarette use, as well as the smoking behavior of older siblings in the household.
Do Emotions Spark Interest in Alternative Tobacco Products?

Exposure to advertisements for tobacco products and tobacco warning labels evokes emotions. This study evaluated the association of discrete positive and negative emotions with interest in alternative tobacco products. In 2013, 1,226 U.S. adult nonsmokers and current smokers viewed advertisements for moist snuff, snus, and electronic cigarettes (e-cigarettes) with various warning labels and then indicated their emotional responses in terms of anger, anxiety, sadness, guilt, disgust, discouragement, hope, and contentment. Outcomes were openness to using moist snuff, snus, and e-cigarettes in the future and interest in a free sample of each product. Data were analyzed in 2016. Hope was positively associated with openness and interest across all alternative tobacco products as was contentment for moist snuff and snus. Anger was negatively associated with openness to moist snuff and e-cigarettes, disgust negatively to moist snuff and snus, and anxiety negatively to e-cigarettes. Being a current smoker, ever trying a corresponding product, being male, and younger age were associated with greater openness to and interest in moist snuff and snus. For e-cigarettes, being a current smoker, ever trying e-cigarettes, and being female were associated with greater openness, and being a current smoker was associated with greater odds of selecting a free sample. Positive emotions, particularly hope, were consistently positively associated with interest in alternative tobacco products. Hope is widely used by tobacco and e-cigarette companies to advertise their products. Antitobacco messages should aim to lower hope associated with tobacco products but increase hope for cessation or life without tobacco.

Disproportionately more smokers report low-income and mental health problems relative to non-smokers. Low-income smokers may use smoking to alleviate negative emotional states resulting from exposure to multiple stressors. Yet, little work has been devoted to elucidating mechanisms that may explain the association between negative emotional states and smoking-related processes among low-income smokers. The present study sought to address this gap by examining anxiety sensitivity, a transdiagnostic factor related to both anxiety and smoking, as a potential mediator for the influence of anxiety symptoms on smoking-related processes, including threat-related smoking abstinence expectancies (somatic symptoms and harmful consequences), perceived barriers for cessation, and problems experienced during past quit attempts. Participants included treatment-seeking daily cigarette smokers (n=101; 68.3% male; M age =47.1; SD=10.2). Results indicated that anxiety symptoms exerted a significant indirect effect through anxiety sensitivity for threat-related smoking abstinence expectancies (somatic symptoms and harmful consequences), perceived barriers for cessation, and problems experienced during past quit attempts. The present results provide empirical support that anxiety sensitivity may be an underlying mechanism that partially explains the relation between anxiety symptoms and smoking processes among low-income treatment-seeking smokers. Findings broaden current theoretical understanding of pathways through which anxiety symptoms contribute to maladaptive smoking processes and cognitions among socioeconomically disadvantaged smokers.

Introduction: Nondaily smokers experience adverse effects from tobacco use, yet they have been understudied compared to daily smokers. Understanding how reasons for smoking (RS) differ by smoking level, gender, and race/ethnicity could inform tailored interventions. Methods: A cross-sectional survey was administered through an online panel survey service to 2,376 current smokers who were at least 25 years of age. The sample was stratified to obtain equal numbers of 3 racial/ethnic groups (African American [AA], Latino, and White) across smoking level (native nondaily, converted nondaily, daily light, and daily moderate/heavy). Results: A 7-factor structure of a 20-item Modified Reasons for Smoking Scale (MRSS) was confirmed (each subscale alpha > 0.80). Each factor of the MRSS varied by smoking level, with nondaily smokers endorsing all RS less frequently than daily smokers (p < .0001). The 4 smoker subgroups incrementally differed from one another (p < .05) with several exceptions between converted nondaily and daily light smokers. Males reported stronger RS on 5 out of 7 reasons (p < .05). Females had higher scores on tension reduction/relaxation (p < .0001). Latinos reported stronger RS than Whites and AAs on all reasons (p < .05) except for tension reduction/relaxation (p > .05). AAs and Whites were comparable on all RS (p > .05). Conclusions: The present study highlights considerable variability across smoking level, gender, and race/ethnicity in strength of RS. Addressing subgroup differences in RS may contribute to more sensitive and effective prevention and treatment efforts. PMID:25011469

Intention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non- smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents.

To refine public health policy amidst a changing landscape of tobacco products in the United States, it is first necessary to describe fully the nature of smokers' alternative product use. Little research addresses smokers' snus use, and most studies are limited by small samples, cross-sectional designs, and crude outcome measurement. This study sample includes 626 adult US smokers who denied intention to quit in the next month and were randomized to receive free snus during a 6-week sampling period, after which no snus was provided. Participants were then followed for one year. Outcome data were collected via phone. Participants (mean age: 48.7years) were predominately female, White non-Hispanic. Eighty-four percent reported trial of snus. Eleven percent reported purchase (i.e., adoption). Current use declined from 47.1% at the end of the sampling period to 6.5% at the end of follow-up. Frequency and quantity of snus use among current users was low. Among snus users, 79.3% said it functioned as an alternative to smoking and 58.4% said it provided a means of coping with smoking restrictions; options not mutually exclusive. In logistic regressions, men were more likely to report trial (odds ratio [OR]=2.33, p<0.01) and adoption (OR=1.84, p<0.05) than women. Baseline expectations about the nature of snus use also predicted snus outcomes (OR=1.28-1.78, p<0.05). Smokers showed willingness to try snus, but product interest waned over time. Snus as currently marketed is unlikely to play a prominent role in US tobacco control efforts. Copyright © 2016 Elsevier Ltd. All rights reserved.
How U.S. adults find out about electronic cigarettes: implications for public health messages.
Pepper, Jessica K; Emery, Sherry L; Ribisl, Kurt M; Brewer, Noel T
2014-08-01
Electronic cigarettes (e-cigarettes) are battery-powered nicotine delivery systems that have become increasingly popular in the United States. We sought to understand how U.S. adults hear about e-cigarettes. A national sample of 17,522 U.S. adults (≥ 18 years old) completed an online survey in March 2013 assessing their awareness of and sources of information about e-cigarettes. Most respondents (86%) had heard of e-cigarettes. Current and former smokers were more likely to be aware of e-cigarettes than non-smokers. Males, younger adults, non-Hispanic Whites, and those with higher education were also more likely to have heard of e-cigarettes. The most commonly reported sources of information were another person, ads on television, and seeing e-cigarettes being sold, although the relative frequency of these sources differed for current, former, and never-smokers. Former and current smokers were more likely to have heard about e-cigarettes from e-cigarette users than were never-smokers. Adults age 30 years or younger were more likely than adults older than 30 years to have heard about e-cigarettes online. Nearly all U.S. adults had heard of e-cigarettes in 2013. By focusing on the most common channels of information, public health campaigns can more efficiently communicate information about e-cigarette safety and consider necessary regulations should companies use these channels for marketing that targets youth, non-tobacco users, and other at-risk groups. © The Author 2014.

Net costs of smoking in a lifetime perspective and, hence, the economic interests in antismoking policies have been questioned. It has been proposed that the health-related costs of smoking are balanced by smaller expenditure due to shorter life expectancy. A dynamic (life cycle) method taking differences in life expectancy into account. Main outcome measures were direct and indirect lifetime health costs for ever-smokers and never-smokers, and cost ratios (ever-smokers to never-smokers). The estimations were based on annual disease rates of use of the healthcare services, smoking relative risks, smoking prevalences, and costs. Annual direct and indirect costs of ever-smokers were higher than for never-smokers in all age groups of both genders. The direct and indirect cost ratios were highest at age 45 for women, and at age 35 and 40 for men, respectively. Taking life expectancy differences into account, direct and indirect lifetime health costs for men aged 35, discounted by 5% per year were 66% and 83% higher in ever-smokers than in never-smokers. Corresponding results for women were 74% and 79%, respectively. The results are insensitive to a broad range of relative risk-estimates and discount rates including no discounting. Excess costs of ever-smokers disappear if the inclusion of smoking-related diseases is narrowed to that of previous studies. Smoking imposes costs to society even when taking life expectancy into consideration--both in direct and indirect costs.

Background Goblet cell hyperplasia is a classic but variable pathologic finding in COPD. Current literature shows that smoking is a risk factor for chronic bronchitis but the relationship of these clinical features to the presence and magnitude of large airway goblet cell hyperplasia has not been well described. We hypothesized that current smokers and chronic bronchitics would have more goblet cells than nonsmokers or those without chronic bronchitis (CB), independent of airflow obstruction. Methods We recruited 15 subjects with moderate to severe COPD, 12 healthy smokers, and 11 healthy nonsmokers. Six endobronchial mucosal biopsies per subject were obtained by bronchoscopy and stained with periodic acid Schiff-Alcian Blue. Goblet cell density (GCD) was quantified as goblet cell number per millimeter of basement membrane. Mucin volume density (MVD) was quantified as volume of mucin per unit area of basement membrane. Results Healthy smokers had a greater GCD and MVD than nonsmokers and COPD subjects. COPD subjects had a greater GCD than nonsmokers. When current smokers (healthy smokers and COPD current smokers, n = 19) were compared with all nonsmokers (nonsmoking controls and COPD ex-smokers, n = 19), current smokers had a greater GCD and MVD. When those with CB (n = 12) were compared to those without CB (n = 26), the CB group had greater GCD. This finding was also seen in those with CB in the COPD group alone. In multivariate analysis, current smoking and CB were significant predictors of GCD using demographics, lung function, and smoking pack years as covariates. All other covariates were not significant predictors of GCD or MVD. Conclusions Current smoking is associated with a more goblet cell hyperplasia and number, and CB is associated with more goblet cells, independent of the presence of airflow obstruction. This provides clinical and pathologic correlation for smokers with and without COPD. PMID:25646735

Not much is known about how people in the Netherlands respond to electronic cigarettes (e-cigarettes); how many know about them, which people try them, keep using them and why, and what are changes over time regarding awareness and use? We used samples of smokers aged 15 years and older from 2008 (n=1820), 2010 (n=1702), 2013 (n=1530), and 2014 (n=1550) as part of the International Tobacco Control (ITC) Netherlands Survey. Reasons for use and characteristics of smokers were examined using the sample from 2014. Logistic regression analyses were conducted to evaluate the associations between smoking-related variables with ever trying e-cigarettes and current e-cigarette use. In 2014, 91.4% of Dutch smokers reported being aware of e-cigarettes (97.1% in 2008, 89.2% in 2010, and 85.5% in 2013), 40.0% reported having ever tried them (13.4% in 2008, 14.5% in 2010, and 19.6% in 2013), and 15.9% were currently using them (4.0% in 2008, 1% in 2010, and 3.9% in 2013). The main reason given for using e-cigarettes was to reduce the number of regular cigarettes smoked per day (79%). Ever trying e-cigarettes among those aware of e-cigarettes was associated with being young, smoking more regular cigarettes per day, having made a quit attempt in the last year, having used smoking cessation pharmacotherapy in the last year, and reporting high awareness of the price of regular cigarettes. Smokers who kept using e-cigarettes had a higher educational background, had higher harm awareness for the health of others, and were less likely to have a total smoking ban at home. E-cigarettes are increasingly used by Dutch smokers. Commonly endorsed motivations for current e-cigarette use were to reduce tobacco smoking and because e-cigarettes are considered to be less harmful than tobacco cigarettes.

Unhealthy smokers: scopes for prophylactic intervention and clinical treatment.

Globally, tobacco use causes approximately 6 million deaths per year, and predictions report that with current trends; more than 8 million deaths are expected annually by 2030. Cigarette smokings is currently accountable for more than 480,000 deaths each year in United States (US) and is the leading cause of preventable death in the US. On average, smokers die 10 years earlier than nonsmokers and if smoking continues at its current proportion among adolescents, one in every 13 Americans aged 17 years or younger is expected to die prematurely from a smoking-related illness. Even though there has been a marginal smoking decline of around 5% in recent years (2005 vs 2015), smokers still account for 15% of the US adult population. What is also concerning is that 41,000 out of 480,000 deaths results from secondhand smoke (SHS) exposure. Herein, we provide a detailed review of health complications and major pathological mechanisms including mutation, inflammation, oxidative stress, and hemodynamic and plasma protein changes associated with chronic smoking. Further, we discuss prophylactic interventions and associated benefits and provide a rationale for the scope of clinical treatment. Considering these premises, it is evident that much detailed translational and clinical studies are needed. Factors such as the length of smoking cessation for ex-smokers, the level of smoke exposure in case of SHS, pre-established health conditions, genetics (and epigenetics modification caused by chronic smoking) are few of the criteria that need to be evaluated to begin assessing the prophylactic and/or therapeutic impact of treatments aimed at chronic and former smokers (especially early stage ex-smokers) including those frequently subjected to second hand tobacco smoke exposure. Herein, we provide a detailed review of health complications and major pathological mechanisms including mutation, inflammation, oxidative stress, and hemodynamic and plasma protein changes associated with chronic smoking. Further, we discuss about prophylactic interventions and associated benefits and provide a rationale and scope for clinical treatment.

Young sexual minority men smoke at higher rates relative to heterosexual peers. The purpose of this study was to examine correlates of smoking in a sample of young gay, bisexual, and other men who have sex with men (MSM) who might differ from more general and age-diverse samples of sexual minority individuals and, thus, inform tailored approaches to addressing tobacco use within this population. Data on smoking status were examined in relation to demographics, mental health, substance use behavior, and psychosocial factors. Using multinomial logistic regression, factors were identified that differentiate current and former smokers from never smokers. In bivariate analysis, smoking status was related to demographic, mental health, substance use, and psychosocial factors. Most significantly, smoking status was associated with school enrollment status, current alcohol and marijuana use, and symptoms of depression. Multivariate modeling revealed that, compared to being a never smoker, the odds of current or former smoking were highest among those currently using either alcohol or marijuana. The odds of both current and former smoking were also higher among those reporting greater levels of gay community affinity. Finally, the odds of being a former smoker were higher for those reporting internalized antihomosexual prejudice. This study identifies several factors related to smoking status in a diverse sample of young sexual minority males. These findings should encourage investigations of smoking disparities among younger MSM to look beyond common smoking risk factors in an attempt to understand etiologies that may be unique to this group. Such findings may indicate multiple points of potential intervention aimed at decreasing cigarette smoking within this vulnerable population.

Objectives. To determine whether persons at high risk of lung cancer would participate in lung cancer screening test if available in Australia and to elicit general attitudes towards cancer screening and factors that might affect participation in a screening program. Methods. We developed a 20-item written questionnaire, based on two published telephone interview scripts, addressing attitudes towards cancer screening, perceived risk of lung cancer, and willingness to be screened for lung cancer and to undertake surgery if lung cancer were detected. The questionnaire was given to 102 current and former smokers attending the respiratory clinic and pulmonary rehabilitation programmes. Results. We gained 90 eligible responses (M:F, 69:21). Mean [SD] age was 63 [11] and smoking history was 32 [21] pack years. 95% of subjects would participate in a lung cancer screening test, and 91% of these would consider surgery if lung cancer was detected. 44% of subjects considered that they were at risk of lung cancer. This was lower in ex-smokers than in current smokers. Conclusions. There is high willingness for lung cancer screening and surgical treatment. There is underrecognition of risk among ex-smokers. This misperception could be a barrier to a successful screening or case-finding programme in Australia. PMID:26316943
Public support in England for raising the price of cigarettes to fund tobacco control activities.
Gardner, Benjamin; West, Robert
2010-08-01
Increasing the price of cigarettes reduces consumption, with a global price elasticity of approximately -0.4. In the UK where the cost of cigarettes is already relatively high, there is an issue surrounding public acceptance of further price rises ahead of the inflation rate. Previous research suggests that price increases may be supported where funds are dedicated to tobacco control. This study assessed public support in England for such a policy. A cross-sectional household survey was conducted in England between August 2008 and January 2009. A representative sample of 8736 respondents aged 16+, of whom 1900 (22%) were cigarette smokers at the time of the survey, was recruited. The primary outcome measure was support for a 20p (4%) price increase on a pack of cigarettes with proceeds going to fund tobacco control activities. 6216 participants (71%), including half (47%) of current cigarette smokers, indicated that they would support a 20p price increase if funds were dedicated to tobacco control activities. Levels of support among smokers were similar across the social gradient and gender. Younger smokers were more likely to support the increase. Smokers who smoked 0-10 cigarettes per day were more supportive of the increase than heavier smokers. There is broad public support for raising the cost of cigarettes with funds being used for tobacco control activities. The absence of a social gradient among smokers concurs with other research showing that more disadvantaged smokers are as engaged with tobacco control objectives as more affluent smokers.

Expanding the information on determinants of smoking cessation is crucial for developing and implementing more effective tobacco control measures at the national as well as European levels. Data on smoking cessation and its social correlates among adults from middle-income countries of Central and Eastern Europe are still poorly reported in the literature. The aim of the study was to analyze the association of socio-demographic indicators with long term tobacco smoking cessation (quit smoking for at least one year prior to interview) among adults. Moreover, we evaluated motives for giving up smoking from former smokers. Data on former as well as current smokers' socio-demographic and smoking-related characteristics were derived from the Global Adult Tobacco Survey (GATS). GATS is a cross-sectional, nationally representative household survey implemented in Poland between 2009 and 2010. GATS collected data on a representative sample of 7,840 individuals including 1,206 individuals who met the criteria of long-term smoking cessation and 2,233 current smokers. Smoking cessation rate was calculated as the number of former smokers divided by the number of ever smokers. Logistic regression analyses were used to obtain odds ratios (ORs) and 95% confidence interval (CI) of the broad number of variables on successful cessation of smoking. Among females the quit rate was 30.4% compared to 37.9% in males (p < 0.01). Former smokers declared concerns about the health hazard of smoking (60.8%) and the high price of cigarettes (11.6%) as primary reasons for smoking cessation. Older age, high education attainment, awareness of smoking health consequences was associated with long-term quitting among both genders. Also employed males had over twice the probability of giving up smoking compared with unemployed, and being religious did not contribute to successful smoking cessation. Results indicated that smoking cessation policies focused on younger age groups are vital for curbing tobacco epidemic in Poland and should become a public health main concern. There is also the need for interventions to raise awareness on smoking health risks and quitting benefits are crucial to increase cessation potential among adult smokers. Nevertheless further effort needs to be done to prevent smoking uptake.

To examine smoking trajectories in a clinical sample of adolescent smokers seeking cessation treatment, including: (a) smoking onset (initial, daily) and time intervals from initial to daily smoking and from daily smoking to treatment request, (b) associations between current level of tobacco dependence and smoking history, and (c) differences in smoking trajectory between African-American and non-African-American youth. Four hundred and thirty-two adolescent smokers (aged 13-17 years, 61.8% female, 32% African-American) responding to various media advertisement completed a telephone interview as part of pre-eligibility screening for a smoking cessation trial. Smoking trajectory data included age at onset of initial and daily smoking, intervals between those time points, and cigarettes smoked per day (CPD). Tobacco dependence was assessed using the Fagerström Test for Nicotine Dependence (FTND). Data were analyzed using regression models and multiple analyses of covariance. Initial smoking occurred at a mean age of less than 12 years and daily smoking at age 13 years. Earlier onset of daily smoking was associated with higher FTND scores and longer duration from daily smoking to treatment request. For the entire sample, the time interval from initial to daily smoking was 1.14 years. When the sample was divided into early (before age 14 years) and later (at or after age 14 years) initiators, early initiators showed a slower progression from initial to daily smoking compared with late initiators (16 months vs. 6 months). Compared with non-African-American teen smokers, African-American youth reported a 1-year delay in onset of both initial and daily smoking. Early age of daily smoking and short time interval from initial to daily smoking highlight a brief window of opportunity to prevent the development of tobacco addiction and its consequences. Ethnic differences in smoking trajectory uncovered in this report call for ethnically tailored interventions to reduce youth smoking.

Through the use of optimal surveillance measures and standard case definitions, it is now possible to more accurately determine population-average risk profiles for severe (SP) and non-severe periodontitis (NSP) in adults (aged 30 years and older) in the United States. Data from the 2009 to 2012 National Health and Nutrition Examination Survey were used, which, for the first time, used the "gold standard" full-mouth periodontitis surveillance protocol to classify severity of periodontitis following suggested Centers for Disease Control/American Academy of Periodontology case definitions. Probabilities of periodontitis by: 1) sociodemographics, 2) behavioral factors, and 3) comorbid conditions were assessed using prevalence ratios (PRs) estimated by predicted marginal probability from multivariable generalized logistic regression models. Analyses were further stratified by sex for each classification of periodontitis. Likelihood of total periodontitis (TP) increased with age for overall and NSP relative to non-periodontitis. Compared with non-Hispanic whites, TP was more likely in Hispanics (adjusted [a]PR = 1.38; 95% confidence interval 95% CI: 1.26 to 1.52) and non-Hispanic blacks (aPR = 1.35; 95% CI: 1.22 to 1.50), whereas SP was most likely in non-Hispanic blacks (aPR = 1.82; 95% CI: 1.44 to 2.31). There was at least a 50% greater likelihood of TP in current smokers compared with non-smokers. In males, likelihood of TP in adults aged 65 years and older was greater (aPR = 2.07; 95% CI: 1.76 to 2.43) than adults aged 30 to 44 years. This probability was even greater in women (aPR = 3.15; 95% CI: 2.63 to 3.77). Likelihood of TP was higher in current smokers relative to non-smokers regardless of sex and periodontitis classification. TP was more likely in men with uncontrolled diabetes mellitus (DM) compared with adults without DM. Assessment of risk profiles for periodontitis in adults in the United States based on gold standard periodontal measures show important differences by severity of disease and sex. Cigarette smoking, specifically current smoking, remains an important modifiable risk for all levels of periodontitis severity. Higher likelihood of TP in older adults and in males with uncontrolled DM is noteworthy. These findings could improve identification of target populations for effective public health interventions to improve periodontal health of adults in the United States.

Aims To evaluate state cigarette excise tax pass-through rates for selected price-minimizing strategies. Design Multivariate regression analysis of current smokers from a stratified, national, dual-frame telephone survey. Setting United States. Participants A total of 16 542 adult current smokers aged 18 years or older. Measurements Cigarette per pack prices paid with and without coupons were obtained for pack versus carton purchase, use of generic brands versus premium brands, and purchase from Indian reservations versus outside Indian reservations. Findings The average per pack prices paid differed substantially by price-minimizing strategy. Smokers who used any type of price-minimizing strategies paid substantially less than those who did not use these strategies (P < 0.05). Premium brand users who purchased by pack in places outside Indian reservations paid the entire amount of the excise tax, together with an additional premium of 7–10 cents per pack for every $1 increase in excise tax (pass-through rate of 1.07–1.10, P < 0.05). In contrast, carton purchasers, generic brand users or those who were likely to make their purchases on Indian reservations paid only 30–83 cents per pack for every $1 tax increase (pass-through rate of 0.30–0.83, P < 0.05). Conclusions Many smokers in the United States are able to avoid the full impact of state excise tax on cost of smoking by buying cartons, using generic brands and buying from Indian reservations.

Previous studies showed inconsistent results concerning the relationship between chronic smoking and blood pressure. Most of the studies involved self-reported smoking status. This study was performed to evaluate the association of urinary cotinine or self-reported smoking status with hypertension and blood pressure in Korean adults. Among individuals enrolled in the Kangbuk Samsung Health Study and Kangbuk Samsung Cohort Study, 167,868 participants (men, 55.7%; age, 37.5 ± 6.9 years) between 2011 and 2013 who had urinary cotinine measurements were included. Individuals with urinary cotinine levels ≥50 ng/mL were defined as cotinine-verified current smokers. The prevalence of hypertension and cotinine-verified current smokers in the overall population was 6.8% and 22.7%, respectively (10.0% in men and 2.8% in women for hypertension: 37.7% in men and 3.9% in women for cotinine-verified current smokers). In a multivariate regression analysis adjusted for age, sex, body mass index, waist circumference, alcohol drinking, vigorous exercise, and diabetes, cotinine-verified current smoking was associated with lower prevalence of hypertension compared with cotinine-verified never smoking (OR[95% CI], 0.79 [0.75, 0.84]). Log-transformed cotinine levels and unobserved smoking were negatively associated with hypertension, respectively (0.96 [0.96, 0.97] and 0.55 [0.39, 0.79]). In a multivariate linear regression analysis, the cotinine-verified current smoking was inversely associated with systolic and diastolic blood pressure (BP) (regression coefficient[95% CI], -1.23[-1.39, -1.07] for systolic BP and -0.71 [-0.84, -0.58] for diastolic BP). In subgroup analyses according to sex, the inverse associations between cotinine-verified current smoking and hypertension were observed only in men. This large observational study showed that cotinine-verified current smoking and unobserved smoking were inversely associated with hypertension in Korean adults, especially only in men.

E-cigarettes may be effective smoking cessation aids and their use by smokers has been growing rapidly. It is important to observe and assess natural patterns in the use of e-cigarettes whilst experimental data accumulates. This paper reports the prevalence of e-cigarette awareness, beliefs and usage, including brand choice, and characterises the socio-demographic and smoking profile associated with current use, among the general population of smokers and recent ex-smokers. Data were obtained from 3538 current and 579 recent ex-smokers in a cross-sectional online survey of a national sample of smokers in Great Britain in November and December 2012. Differences between current and recent ex-smokers in the prevalence of e-cigarette awareness, beliefs and usage were examined and the socio-demographic and smoking profile associated with current use of e-cigarettes was assessed in a series of simple and multiple logistic regressions. Ninety-three percent of current and recent ex-smokers (n=3841) were aware of e-cigarettes. Approximately a fifth (n=884) were currently using e-cigarettes, whilst just over a third (n=1507) had ever used them. Sixty-seven percent of the sample (n=2758) believed e-cigarettes to be less harmful than cigarettes; however, almost a quarter (n=994) remained unsure. Among both current and recent ex-smokers, the most popular reasons for using were health, cutting down and quitting (each >80%) and 38% used the brand 'E-lites'. Among current smokers who were aware of but had never used e-cigarettes, approximately half (n=1040) were interested in using them in the future. Among current smokers, their use was associated with higher socio-economic status (OR=1.48, 95%CI=1.25-1.75), smoking more cigarettes (OR=1.02, 95%CI=1.01-1.03) and having a past-year quit attempt (OR=2.82, 95%CI=2.38-3.34). There is a near universal awareness of e-cigarettes and their use appears to be common among smokers in Great Britain although a quarter of all smokers are unsure as to whether e-cigarettes are less harmful than cigarettes. E-lites - a brand that delivers a low dose of nicotine - is the most popular. E-cigarette users appear to have higher socio-economic status, to smoke more cigarettes per day and to have attempted to quit in the past year. Copyright © 2014 The Authors.

To study the attitudes toward smoking of employees of the Federal University of Sao Paulo as a step toward implanting a consensualized anti-smoking program for the institution. We designed and distributed anonymous, self-completed questionnaires with 51 multiple-choice questions, which were returned by 2,613 (48.6%) employees, professors, medical residents, nurses and students. Four hundred thirty-eight (16.8% of the population) of the respondents were smokers and 456 (17.5%) were non-smokers. For 84% smoking started between the ages of 11 and 20 years. Most smokers were between 31 and 40 years of age, and the prevalence of ex-smokers was highest in respondents over the age of 60. Seventy-eight percent of the smokers smoked at work. Both smokers and non-smokers reported some type of discomfort caused by cigarette smoke, mainly smell in clothes and hair (62.7% of smokers versus 59% of non-smokers, NS). The proportion who opted for a totally smoke-free environment was 37.5% among non-smokers and 10% among smokers (p < 0.05). Restrictions on smoking in specific places, on the other hand, met with the approval of 82.8% of smokers and 59% of non-smokers (p < 0.05). We believe that surveys such as this one should be carried out at all institutions, particularly in health care centers, in order to assure that smoking restriction policies are successful and receive the support of most employees, whether they smoke or not. Our data suggest the advisability of creating restricted-smoking zones in the early phase of an institutional anti-smoking campaign designed to lead to a totally smoke-free workplace environment.

Electronic cigarette (e-cigarette) marketing has increased considerably since the product entered the US market in 2007, thereby warranting additional surveillance to monitor recent trends in population-level awareness and utilization. We assessed the prevalence, characteristics, and trends in e-cigarette awareness and use among nationally representative samples of US adults during 2010-2013. Data came from the 2010-2013 HealthStyles survey, an annual consumer-based web survey of US adults aged ≥ 18 years. Sample sizes ranged from 2,505 (2010) to 4,170 (2012). Descriptive statistics were used to assess e-cigarette awareness, ever use, and current use (use within the past 30 days) overall and by sex, age, race/ethnicity, education, income, US region, and cigarette smoking status. Trends were assessed using logistic regression. During 2010-2013, increases (p < .05) were observed for e-cigarette awareness (40.9%-79.7%), ever use (3.3%-8.5%), and current use (1.0%-2.6%). Awareness increased among all socio demographic subpopulations during 2010-2013 (p < .05); an increase in ever use of e-cigarettes occurred among all sociodemographic groups except those aged 18-24 years, Hispanics, and those living in the Midwest (p < .05). During 2010-2013, ever use increased among current (9.8%-36.5%) and former (2.5%-9.6%) cigarette smokers (p < .05), but it remained unchanged among never smokers (1.3%-1.2%). Awareness and use of e-cigarettes increased considerably among US adults during 2010-2013. In 2013, more than one-third of current cigarette smokers reported having ever used e-cigarettes. Given the uncertain public health impact of e-cigarettes, continued surveillance of emerging use patterns is critical for public health planning.

Teen use of flavored tobacco products is a concern. Menthol cigarettes have been found to influence teen smoking; however, less is known about the association between teen use of other flavored tobacco products, such as cigars and dip, and cigarette smoking. The New York City 2010 Special Communities Putting Prevention to Work Youth Risk Behavior Survey data (N = 1,800 aged 13-17 years) were analyzed to examine the association between ever trying flavored tobacco products and current smoking, after we adjusted for demographics and ever-use of menthol cigarettes. Twenty percent of teens reported ever trying flavored tobacco products; youth who were current smokers (58%) were more likely to have tried flavored tobacco products than youth who were not current smokers (16%). Controlling for menthol cigarette use, teens who had ever tried flavored tobacco products were nearly 3 times more likely to be current smokers than those who had never tried flavored tobacco products (odds ratio = 2.70, 95% confidence interval = 1.47-4.98). Ever trying flavored tobacco products was strongly associated with current smoking among teens. The findings from this study suggest that regulations prohibiting sales of flavored tobacco products could decrease youth smoking.

AIM To analyzed the correlation between smoking status and surgical outcomes in patients with non-B non-C hepatocellular carcinoma (NBNC-HCC), and we investigated the patients’ clinicopathological characteristics according to smoking status. METHODS We retrospectively analyzed the consecutive cases of 83 NBNC-HCC patients who underwent curative surgical treatment for the primary lesion at Saga University Hospital between 1984 and December 2012. We collected information about possibly carcinogenic factors such as alcohol abuse, diabetes mellitus, obesity and smoking habit from medical records. Smoking habits were subcategorized as never, ex- and current smoker at the time of surgery. The diagnosis of non-alcoholic steatohepatitis (NASH) was based on both clinical information and pathological confirmation. RESULTS Alcohol abuse, diabetes mellitus, obesity and NASH had no significant effect on the surgical outcomes. Current smoking status was strongly correlated with both overall survival (P = 0.0058) and disease-specific survival (P = 0.0105) by multivariate analyses. Subset analyses revealed that the current smokers were significantly younger at the time of surgery (P = 0.0002) and more likely to abuse alcohol (P = 0.0188) and to have multiple tumors (P = 0.023). CONCLUSION Current smoking habit at the time of surgical treatment is a risk factor for poor long-term survival in NBNC-HCC patients. Current smokers tend to have multiple HCCs at a younger age than other patients. PMID:28293086

To analyzed the correlation between smoking status and surgical outcomes in patients with non-B non-C hepatocellular carcinoma (NBNC-HCC), and we investigated the patients' clinicopathological characteristics according to smoking status. We retrospectively analyzed the consecutive cases of 83 NBNC-HCC patients who underwent curative surgical treatment for the primary lesion at Saga University Hospital between 1984 and December 2012. We collected information about possibly carcinogenic factors such as alcohol abuse, diabetes mellitus, obesity and smoking habit from medical records. Smoking habits were subcategorized as never, ex- and current smoker at the time of surgery. The diagnosis of non-alcoholic steatohepatitis (NASH) was based on both clinical information and pathological confirmation. Alcohol abuse, diabetes mellitus, obesity and NASH had no significant effect on the surgical outcomes. Current smoking status was strongly correlated with both overall survival ( P = 0.0058) and disease-specific survival ( P = 0.0105) by multivariate analyses. Subset analyses revealed that the current smokers were significantly younger at the time of surgery ( P = 0.0002) and more likely to abuse alcohol ( P = 0.0188) and to have multiple tumors ( P = 0.023). Current smoking habit at the time of surgical treatment is a risk factor for poor long-term survival in NBNC-HCC patients. Current smokers tend to have multiple HCCs at a younger age than other patients.

Considerable erosion of gains have often been found during follow-up periods for behavioral treatment programs directed towards adult smokers. Focusing more attention on preventing smoking among youngsters currently not smoking or reducing smoking among those just beginning the habit might produce more favorable results. (Author)

Smoking is known to suppress the immune system. It is also known that chronic renal failure affects the immune system. However, the number of studies investigating the effects of chronic renal failure and smoking together is limited. In our study, we examined whether smoking affects the diminished response of the immune system in patients with chronic renal failure. We compared peripheral blood lymphocyte subsets in smoking and nonsmoking patients with chronic renal failure. We also used the Fagerström Test for Nicotine Dependence to evaluate its correlation with the lymphocyte subset count in patients who are current smokers. Our study included 126 patients with chronic renal failure. According to their smoking habits, patients were divided into 2 groups: smokers and nonsmokers. The average age of patients who were smokers was 53.2 ± 1.5 years, with average age of nonsmokers being 59.2 ± 2.2 years. The average duration of smoking in smokers was 30.7 ± 2.7 packyears. We found that the percentage of cluster of differentiation 16-56 cells (natural killer cells) and lymphocyte percentage were significantly lower among smokers in our study (P < .05). We compared the lymphocyte subset panel to pack-years and found that the rate of cluster of differentiation 16-56 cells decreased as smoking duration increased. Our study revealed that smoking suppresses the immune system, as measured by lymphocyte subsets, in patients with chronic renal failure, similar to that shown in healthy smokers. According to our findings, patients with chronic renal failure, where infection is the primary reason for mortality and morbidity, must be questioned for smoking and referred to smoking cessation clinics. Because of its immunosuppressive effects, smoking behaviors must be solved preoperatively in transplant candidates.

Smokers' health-related outcome expectancies are associated with a number of important constructs in smoking research, yet there are no measures currently available that focus exclusively on this domain. This paper describes the development and evaluation of item banks for assessing the health expectancies of smoking. Using data from a sample of daily (N = 4,201) and nondaily (N = 1,183) smokers, we conducted a series of item factor analyses, item response theory analyses, and differential item functioning analyses (according to gender, age, and race/ethnicity) to arrive at a unidimensional set of health expectancies items for daily and nondaily smokers. We also evaluated the performance of short forms (SFs) and computer adaptive tests (CATs) to efficiently assess health expectancies. A total of 24 items were included in the Health Expectancies item banks; 13 items are common across daily and nondaily smokers, 6 are unique to daily, and 5 are unique to nondaily. For both daily and nondaily smokers, the Health Expectancies item banks are unidimensional, reliable (reliability = 0.95 and 0.96, respectively), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.87). Results from simulated CATs showed that health expectancies can be assessed with good precision with an average of 5-6 items adaptively selected from the item banks. Health expectancies of smoking can be assessed on the basis of these item banks via SFs, CATs, or through a tailored set of items selected for a specific research purpose. © The Author 2014.

Smoking behaviour and its course is influenced by personality factors. Affective temperaments could allow a more specific framework of the role trait affectivity plays in this seriously harmful health-behaviour. The aim of our study was to investigate if such an association exists in an ageing population with a special emphasis on gender differences. 459 primary care patients completed the TEMPS-A, Beck Depression Inventory (BDI) and Hamilton Anxiety Rating Scale (HAM-A). Subjects were characterized according to their smoking behaviour as current, former or never smokers. Univariate analysis ANOVA and logistic regression were performed to analyse differences in the three smoking subgroups to predict smoking initiation and maintenance. Current smokers were younger and less educated than former or never smokers. Males were more likely to try tobacco during their lifetime and were more successful in cessation. Depressive, cyclothymic and irritable temperament scores showed significant differences between the three smoking subgroups. Irritable temperament was a predictor of smoking initiation in females whereas depressive temperament predicted smoking maintenance in males with a small, opposite effect of HAM-A scores independent of age, education, lifetime depression and BDI scores. Whereas smoking initiation was exclusively predicted by a higher BDI score in males, smoking maintenance was predicted by younger age and lower education in females. The cross-sectional nature of the study design may lead to selective survival bias and hinder drawing causal relationships. Affective temperaments contribute to smoking initiation and maintenance independently of age, education, and depression. The significant contribution of depressive temperament in males and irritable temperament in females may highlight the role of gender-discordant temperaments in vulnerable subgroups.

Importance The US Preventive Services Task Force (USPSTF) recommends computed-tomography (CT) lung-cancer screening for ever-smokers ages 55-80 years who smoked at least 30 pack-years with no more than 15 years since quitting. However, selecting ever-smokers for screening using individualized lung-cancer risk calculations may be more effective and efficient than current USPSTF recommendations. Objective Comparison of modeled outcomes from risk-based CT lung-screening strategies versus USPSTF recommendations. Design/Setting/Participants Empirical risk models for lung-cancer incidence and death in the absence of CT screening using data on ever-smokers from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (PLCO; 1993-2009) control group. Covariates included age, education, sex, race, smoking intensity/duration/quit-years, Body Mass Index, family history of lung-cancer, and self-reported emphysema. Model validation in the chest radiography groups of the PLCO and the National Lung Screening Trial (NLST; 2002-2009), with additional validation of the death model in the National Health Interview Survey (NHIS; 1997-2001), a representative sample of the US. Models applied to US ever-smokers ages 50-80 (NHIS 2010-2012) to estimate outcomes of risk-based selection for CT lung-screening, assuming screening for all ever-smokers yields the percent changes in lung-cancer detection and death observed in the NLST. Exposure Annual CT lung-screening for 3 years. Main Outcomes and Measures Model validity: calibration (number of model-predicted cases divided by number of observed cases (Estimated/Observed)) and discrimination (Area-Under-Curve (AUC)). Modeled screening outcomes: estimated number of screen-avertable lung-cancer deaths, estimated screening effectiveness (number needed to screen (NNS) to prevent 1 lung-cancer death). Results Lung-cancer incidence and death risk models were well-calibrated in PLCO and NLST. The lung-cancer death model calibrated and discriminated well for US ever-smokers ages 50-80 (NHIS 1997-2001: Estimated/Observed=0.94, 95%CI=0.84-1.05; AUC=0.78, 95%CI=0.76-0.80). Under USPSTF recommendations, the models estimated 9.0 million US ever-smokers would qualify for lung-cancer screening and 46,488 (95%CI=43,924-49,053) lung-cancer deaths were estimated as screen-avertable over 5 years (estimated NNS=194, 95%CI=187-201). In contrast, risk-based selection screening the same number of ever-smokers (9.0 million) at highest 5-year lung-cancer risk (≥1.9%), was estimated to avert 20% more deaths (55,717; 95%CI=53,033-58,400) and was estimated to reduce the estimated NNS by 17% (NNS=162, 95%CI=157-166). Conclusions and Relevance Among a cohort of US ever-smokers age 50-80 years, application of a risk-based model for CT screening for lung cancer compared with a model based on USPSTF recommendations was estimated to be associated with a greater number of lung-cancer deaths prevented over 5 years along with a lower NNS to prevent 1 lung-cancer death.

To evaluate the risk of aortic aneurysm in patients with giant cell arteritis (GCA) compared with age-, gender- and location-matched controls. A UK General Practice Research Database (GPRD) parallel cohort study of 6999 patients with GCA and 41 994 controls, matched on location, age and gender, was carried out. A competing risk model using aortic aneurysm as the primary outcome and non-aortic-aneurysm-related death as the competing risk was used to determine the relative risk (subhazard ratio) between non-GCA and GCA subjects, after adjustment for cardiovascular risk factors. Comparing the GCA cohort with the non-GCA cohort, the adjusted subhazard ratio (95% CI) for aortic aneurysm was 1.92 (1.52 to 2.41). Significant predictors of aortic aneurysm were being an ex-smoker (2.64 (2.03 to 3.43)) or a current smoker (3.37 (2.61 to 4.37)), previously taking antihypertensive drugs (1.57 (1.23 to 2.01)) and a history of diabetes (0.32 (0.19 to 0.56)) or cardiovascular disease (1.98 (1.50 to 2.63)). In a multivariate model of the GCA cohort, male gender (2.10 (1.38 to 3.19)), ex-smoker (2.20 (1.22 to 3.98)), current smoker (3.79 (2.20 to 6.53)), previous antihypertensive drugs (1.62 (1.00 to 2.61)) and diabetes (0.19 (0.05 to 0.77)) were significant predictors of aortic aneurysm. Patients with GCA have a twofold increased risk of aortic aneurysm, and this should be considered within the range of other risk factors including male gender, age and smoking. A separate screening programme is not indicated. The protective effect of diabetes in the development of aortic aneurysms in patients with GCA is also demonstrated.

This paper provides misclassification rates for current cigarette smokers who report themselves as nonsmokers. Such rates are important in determining smoker misclassification bias in the estimation of relative risks in passive smoking studies. True smoking status, either occasional or regular, was determined for individual current smokers in 3 existing studies of nonsmokers by inspecting the cotinine levels of body fluids. The new data, combined with an approximately equal amount in the 1992 Environmental Protection Agency (EPA) report on passive smoking and lung cancer, yielded misclassification rates that not only had lower standard errors but also were stratified by sex and US minority majority status. The misclassification rates for the important category of female smokers misclassified as never smokers were, respectively, 0.8%, 6.0%, 2.8%, and 15.3% for majority regular, majority occasional, US minority regular, and US minority occasional smokers. Misclassification rates for males were mostly somewhat higher. The new information supports EPA's conclusion that smoker misclassification bias is small. Also, investigators are advised to pay attention to minority/majority status of cohorts when correcting for smoker misclassification bias.
Effect of anti-smoking advertisements on Turkish adolescents.

The aim of the present study was to determine the perception of 10 anti-smoking advertisements in 1434 Turkish adolescents. We used the Effectiveness of the Anti-smoking Advertisements Scale, which included 6 items for each advertisement; each item was assessed on a 5-point Likert-type scale. Multiple logistic regression analysis was used to determine the factors associated with the impact of the advertisements. All the advertisements were more effective for adolescents who had never smoked compared to ex-smokers and current smokers. We also noted that, regardless of age, smoking status decreased the effectiveness of all the advertisements. Previous studies have shown that smokers have a negative attitude towards anti-smoking messages. In the present study, the most effective advertisements among adolescents were those with "Sponge and tar", "Smoking harms in every breath" and "Children want to grow". In conclusion, although anti-smoking campaigns are targeted towards adults, they also have a strong influence on adolescents. The main target population for advertisements should be individuals aged < 15 years who have not yet started smoking.

IMPORTANCE Airflow obstruction on spirometry is universally used to define chronic obstructive pulmonary disease (COPD), and current or former smokers without airflow obstruction may assume that they are disease free. OBJECTIVE To identify clinical and radiologic evidence of smoking-related disease in a cohort of current and former smokers who did not meet spirometric criteria for COPD, for whom we adopted the discarded label of Global Initiative for Obstructive Lung Disease (GOLD) 0. DESIGN, SETTING, AND PARTICIPANTS Individuals from the Genetic Epidemiology of COPD (COPDGene) cross-sectional observational study completed spirometry, chest computed tomography (CT) scans, a 6-minute walk, and questionnaires. Participants were recruited from local communities at 21 sites across the United States. The GOLD 0 group (n = 4388) (ratio of forced expiratory volume in the first second of expiration [FEV1] to forced vital capacity >0.7 and FEV1 ≥80% predicted) from the COPDGene study was compared with a GOLD 1 group (n = 794), COPD groups (n = 3690), and a group of never smokers (n = 108). Recruitment began in January 2008 and ended in July 2011. MAIN OUTCOMES AND MEASURES Physical function impairments, respiratory symptoms, CT abnormalities, use of respiratory medications, and reduced respiratory-specific quality of life. RESULTS One or more respiratory-related impairments were found in 54.1% (2375 of 4388) of the GOLD 0 group. The GOLD 0 group had worse quality of life (mean [SD] St George’s Respiratory Questionnaire total score, 17.0 [18.0] vs 3.8 [6.8] for the never smokers; P < .001) and a lower 6-minute walk distance, and 42.3% (127 of 300) of the GOLD 0 group had CT evidence of emphysema or airway thickening. The FEV1 percent predicted distribution and mean for the GOLD 0 group were lower but still within the normal range for the population. Current smoking was associated with more respiratory symptoms, but former smokers had greater emphysema and gas trapping. Advancing age was associated with smoking cessation and with more CT findings of disease. Individuals with respiratory impairments were more likely to use respiratory medications, and the use of these medications was associated with worse disease. CONCLUSIONS AND RELEVANCE Lung disease and impairments were common in smokers without spirometric COPD. Based on these results, we project that there are 35 million current and former smokers older than 55 years in the United States who may have unrecognized disease or impairment. The effect of chronic smoking on the lungs and the individual is substantially underestimated when using spirometry alone. PMID:26098755

Gender and the smoking behaviour of Ethiopian immigrants in Toronto.
Hyman, I; Fenta, H; Noh, S
2008-01-01
The objective of this paper is to present descriptive data on gender and smoking among Ethiopian immigrants in Toronto, Canada. The study used a cross-sectional epidemiological survey design (N = 342). The main outcome measures identified subjects as current (regular or occasional) smokers, daily smokers and former smokers. Overall, 20.8% of the individuals in the sample were current smokers and 15.7% were daily smokers. Although smoking rates (current and daily) were significantly higher among males compared to females, nearly twice as many female as male daily smokers reported that they began smoking post-migration (60.0% vs. 30.2%). Furthermore, 80.0% of female compared to nearly 56% of male daily smokers reported that they were smoking more post-migration. A significantly higher proportion of males compared to females were former daily smokers (17.8% vs. 4.4%). These findings present a challenge for public health professionals in terms of preventing the adoption of smoking among Ethiopian females and facilitating smoking cessation among Ethiopian males. Correlates with current smoking suggested that smoking prevention and cessation programs in newcomer immigrant communities may benefit from incorporating social, economic and religious contexts of these newcomers' lives from a gender-specific perspective.

The US Food and Drug Administration has established a policy of substantially discounting the health benefits of reduced smoking in its evaluation of proposed regulations because of the cost to smokers of the supposed lost pleasure they suffer by no longer smoking. This study used data from nine countries of the former Soviet Union (fSU) to explore this association in a setting characterised by high rates of (male) smoking and smoking-related mortality. Data came from a cross-sectional population-based study undertaken in 2010/2011 in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine. Information was collected from 18 000 respondents aged ≥18 on smoking status (never, ex-smoking and current smoking), cessation attempts and nicotine dependence. The association between these variables and self-reported happiness was examined using ordered probit regression analysis. In a pooled country analysis, never smokers and ex-smokers were both significantly happier than current smokers. Smokers with higher levels of nicotine dependence were significantly less happy than those with a low level of dependence. This study contradicts the idea that smoking is associated with greater happiness. Moreover, of relevance for policy in the fSU countries, given the lack of public knowledge about the detrimental effects of smoking on health but widespread desire to quit reported in recent research, the finding that smoking is associated with lower levels of happiness should be incorporated in future public health efforts to help encourage smokers to quit by highlighting that smoking cessation may result in better physical and emotional health.

It is well established that smoking has a myriad of negative effects on varies aspects of bodily health. The aim of this study was to examine the effects of the smoking status at time of surgery on the postoperative subjective pain course and health related quality of life (HRQoL) until 1 year after surgery for lumbar disc herniation (LDH). This prospective cohort study included patients ≥18 and ≤90 years of age with a symptomatic and radiological verified LDH. The current smoking patient collective (smoking 1 or more cigarettes a day) was compared with the nonsmoking collective (previous smokers without cigarette consumption for >2 months and never smokers) in respect of subjective pain sensation (measured with the visual analogue scale (VAS)) and HRQoL using the short-form (SF-12) questionnaire preoperatively, before discharge, as well as after 4 weeks and 1 year postoperatively. The primary outcome measures were the 1-year SF-12 scores (MCS and PCS) categorized into responders and non-responders. A total of 102 patients were enrolled in the study. Thirty-eight patients were current smokers (37.2%), whereas 43 (42.2%) and 21 (20.6%) patients were never-smokers and previous smokers, respectively. Four weeks and one year after surgery, both smokers and nonsmokers reported increase in the HRQoL as compared to preoperative values - the MCS increased more than the PCS. From a univariate and multivariate perspective, smoking status at time of surgery did not predict responder status. The present study results could not confirm the hypothesis that smoking at time of surgery was associated with worse outcome after surgery for LDH. Copyright © 2014 Elsevier B.V. All rights reserved.

Both active smoking and exposure to secondhand smoke (SHS) are associated with cardiovascular disease, but sidestream smoke contains higher levels of small particles and toxic gases than mainstream smoke. The relationship between the concentration of cotinine and a number of cardiovascular biomarkers among nonsmokers and active smokers was examined. A cross-sectional study using the Scottish Health Surveys conducted between 1998 and 2010 was undertaken. Inclusion was restricted to participants aged ≥16 years who had provided saliva and blood samples. Uni- and multivariate regression models were used to examine the relationships between the concentration of cotinine and C-reactive protein (CRP), high-density lipoprotein (HDL) cholesterol, and fibrinogen concentrations, as well as total:HDL cholesterol ratios. Of the 10,018 eligible participants, 7,345 (73.3%) were confirmed to be nonsmokers (cotinine <15.0 ng/mL) and 2,673 (26.7%) were confirmed to be current smokers (cotinine ≥15.0 ng/mL). CRP and total:HDL cholesterol increased, and HDL cholesterol decreased, with increasing cotinine concentration across nonsmokers and smokers (all p < .001). However, there were step changes at the interface, whereby nonsmokers with a high exposure to SHS had lower concentrations of cotinine than light active smokers but comparable concentrations of CRP (p = .709), HDL cholesterol (p = .931), and total:HDL cholesterol (p = .405). Fibrinogen concentrations were significantly raised in moderate and heavy active smokers only (both p < .001). Exposure to SHS is associated with disproportionately higher biomarkers of cardiovascular risk compared with active smoking. Protection from exposure to SHS should be a public health priority.

To examine the association of smoking status, smoking intensity, and smoking cessation with the risk of type 2 diabetes (T2D) using a large database. The present study included 53,930 Japanese employees, aged 15 to 83 years, who received health check-up and did not have diabetes at baseline. Diabetes was defined as fasting plasma glucose ≥126 mg/dl, random plasma glucose ≥200 mg/dl, HbA1c ≥6.5% (≥48 mmol/mol), or receiving medication for diabetes. Cox proportional-hazards regression models were used to investigate the association between smoking and the risk of diabetes. During 3.9 years of median follow-up, 2,441 (4.5%) individuals developed T2D. The multivariable-adjusted hazard ratios (95% CI) for diabetes were 1 (reference), 1.16 (1.04 to 1.30) and 1.34 (1.22 to 1.48) for never smokers, former smokers, and current smokers, respectively. Diabetes risk increased with increasing numbers of cigarette consumption among current smokers (P for trend <0.001). Although the relative risk of diabetes was greater among subjects with lower BMIs (< 23 kg/m2), attributable risk was greater in subjects with higher BMIs (≥ 23 kg/m2). Compared with individuals who had never smoked, former smokers who quit less than 5 years, 5 to 9 years, and 10 years or more exhibited hazards ratios for diabetes of 1.36 (1.14 to 1.62), 1.23 (1.01 to 1.51), and 1.02 (0.85 to 1.23), respectively. Results suggest that cigarette smoking is associated with an increased risk of T2D, which may decrease to the level of a never smoker after 10 years of smoking cessation.

Findings of surface-based morphometry studies in major depressive disorder (MDD) are still inconsistent. Given that cigarette smoking is highly prevalent in MDD and has documented negative effects on the brain, it is possible that some of the inconsistencies may be partly explained by cigarette use. The aim of the current study was to examine the influence of cigarette smoking on brain structure in MDD. 50 MDD patients (25 smokers and 25 non-smokers) and 22 age, education, gender and BMI matched non-smoker healthy controls underwent structural magnetic resonance imaging. Thickness and area of the cortex were measured using surface-based morphometry implemented with Freesurfer (v5.3.0). The non-smoker MDD patients had significantly increased cortical thickness, including in the left temporal cortex (p < 0.001), right insular cortex (p = 0.033) and left pre- and postcentral gyrus (p = 0.045), compared to healthy controls. We also found decreased cortical thickness in MDD patients who smoked compared to non-smoking patients in regions that overlapped with the regions found to be increased in non-smoking patients in comparison to controls. Non-smoker MDD patients had increased surface area in the right lateral occipital cortex (p = 0.009). We did not find any region where cortical thickness or surface area significantly differed between controls and either smoker MDD patients or all MDD patients. The findings of the current study suggest that cigarette smoking is associated with cortical thinning in regions found to be increased in patients with MDD. However, these results should be considered preliminary due to methodological limitations. Copyright © 2016 Elsevier Ltd. All rights reserved.

Population-level communication interventions, such as graphic warning labels (GWLs) on cigarette packs, have the potential to reduce or exacerbate tobacco-related health disparities depending on their effectiveness among disadvantaged sub-populations. This study evaluated the likely impact of nine GWLs proposed by the US Food and Drug Administration on (1) African American and (2) Hispanic smokers, who disproportionately bear the burden of tobacco-related illness, and (3) low education smokers, who have higher smoking rates. Data were collected online from current smokers randomly assigned to see GWLs (treatment) or the current text-only warning labels (control). Participants were stratified by age (18-25; 26+) in each of four groups: general population (n = 1246), African Americans (n = 1200), Hispanics (n = 1200), and low education (n = 1790). We tested the effectiveness of GWLs compared to text-only warning labels using eight outcomes that are predictive of quitting intentions or behaviors including negative emotion, intentions to hold back from smoking, intentions to engage in avoidance behaviors, and intentions to quit. Across all outcomes, GWLs were significantly more effective than text-only warning labels more often than expected by chance. Results suggested that African Americans, Hispanics and smokers with low education did not differ from the general population of smokers in their reactions to any of the nine individual GWLs. The nine GWLs were similarly effective for disadvantaged sub-populations and the general population of smokers. Implementation of GWLs is therefore unlikely to reduce or exacerbate existing tobacco-related health disparities, but will most likely uniformly increase intentions and behaviors predictive of smoking cessation. © The Author 2015.

Introduction: Population-level communication interventions, such as graphic warning labels (GWLs) on cigarette packs, have the potential to reduce or exacerbate tobacco-related health disparities depending on their effectiveness among disadvantaged sub-populations. This study evaluated the likely impact of nine GWLs proposed by the US Food and Drug Administration on (1) African American and (2) Hispanic smokers, who disproportionately bear the burden of tobacco-related illness, and (3) low education smokers, who have higher smoking rates. Methods: Data were collected online from current smokers randomly assigned to see GWLs (treatment) or the current text-only warning labels (control). Participants were stratified by age (18–25; 26+) in each of four groups: general population (n = 1246), African Americans (n = 1200), Hispanics (n = 1200), and low education (n = 1790). We tested the effectiveness of GWLs compared to text-only warning labels using eight outcomes that are predictive of quitting intentions or behaviors including negative emotion, intentions to hold back from smoking, intentions to engage in avoidance behaviors, and intentions to quit. Results: Across all outcomes, GWLs were significantly more effective than text-only warning labels more often than expected by chance. Results suggested that African Americans, Hispanics and smokers with low education did not differ from the general population of smokers in their reactions to any of the nine individual GWLs. Conclusions: The nine GWLs were similarly effective for disadvantaged sub-populations and the general population of smokers. Implementation of GWLs is therefore unlikely to reduce or exacerbate existing tobacco-related health disparities, but will most likely uniformly increase intentions and behaviors predictive of smoking cessation.

Urinary cadmium and blood pressure: results from the NHANES II survey.

Relationships between urinary cadmium levels and blood pressure were examined in a sample of 951 adult men and women who participated in the Second National Health and Nutritional Examination Survey (NHANES II). Among all participants, positive relationships were seen between urinary cadmium levels and both systolic and diastolic blood pressure (p less than 0.05 and p less than 0.01, respectively), after adjusting for age, sex, race, relative body weight, smoking status, and hypertensive medication use. However, analyses for subgroups determined by sex and smoking status were inconsistent. Among current smokers, urinary cadmium levels were significantly positively associated with both systolic and diastolic blood pressure for women, and with diastolic blood pressure for men. Yet among former smokers and lifelong nonsmokers of both sexes, urinary cadmium was not significantly associated with either systolic or diastolic blood pressure. Evidence that some hypertensive medications increase urinary cadmium excretion suggests that the positive associations seen among current smokers may reflect high urinary cadmium levels among hypertensives induced by hypertensive treatment. After treated hypertensives were removed from the analysis, regression coefficients relating blood pressure to cadmium dropped by a factor of two and lost statistical significance. We conclude that the present data provide little support for a causal association between systemic cadmium and hypertension at nonoccupational exposure levels. Further, conflicting results of previous studies may reflect failure to control adequately for age, smoking status, and hypertensive treatment. PMID:2040243

No previous review has formally modelled the decline in IHD risk following quitting smoking. From PubMed searches and other sources we identified 15 prospective and eight case-control studies that compared IHD risk in current smokers, never smokers, and quitters by time period of quit, some studies providing separate blocks of results by sex, age or amount smoked. For each of 41 independent blocks, we estimated, using the negative exponential model, the time, H, when the excess risk reduced to half that caused by smoking. Goodness-of-fit to the model was adequate for 35 blocks, others showing a non-monotonic pattern of decline following quitting, with a variable pattern of misfit. After omitting one block with a current smoker RR 1.0, the combined H estimate was 4.40 (95% CI 3.26-5.95) years. There was considerable heterogeneity, H being <2years for 10 blocks and >10years for 12. H increased (p<0.001) with mean age at study start, but not clearly with other factors. Sensitivity analyses allowing for reverse causation, or varying assumed midpoint times for the final open-ended quitting period little affected goodness-of-fit of the combined estimate. The US Surgeon-General's view that excess risk approximately halves after a year's abstinence seems over-optimistic. Copyright © 2012 Elsevier Inc. All rights reserved.

We examined the exposure to tobacco direct mail marketing and its effect on subsequent smoking behaviors in a US Midwest regional cohort of young adults. Data were collected from 2622 young adults (mean age = 24 years) in 2010 to 2011 (baseline) and 2011 to 2012 (follow-up). We collected information on demographics, tobacco use, and exposure to tobacco direct mail materials in the previous 6 months at baseline. Smoking behaviors were reassessed at follow-up. We investigated the characteristics associated with receiving these materials at baseline, and the associations between receiving cigarette coupons in the mail at baseline and smoking behaviors at follow-up. Thirteen percent of participants reported receiving tobacco direct mail materials in the previous 6 months. Receipt of these materials was associated with age, education, and tobacco use (P < .05). Among those who received these materials, 77% and 56% reported receiving coupons for cigarettes and other tobacco products, respectively. Among baseline nonsmokers and ex-smokers, receiving coupons was associated with becoming current smokers at follow-up (P < .05). Among baseline current smokers, receiving coupons was associated with lower likelihood of smoking cessation at follow-up (P < .05). Tobacco direct mail marketing promoted and sustained smoking behaviors among US Midwest young adults. Regulating this marketing strategy might reduce the prevalence of smoking in this population.

The goal of this study was to conduct a preliminary network analysis (using graph-theory measures) of intrinsic functional connectivity in adult smokers, with an exploration of sex differences in smokers. Twenty-seven adult smokers (13 males; mean age = 35) and 17 sex and age-matched controls (11 males; mean age = 35) completed a blood oxygen level-dependent resting state functional magnetic resonance imaging experiment. Data analysis involved preprocessing, creation of connectivity matrices using partial correlation, and computation of graph-theory measures using the Brain Connectivity Toolbox. Connector hubs and additional graph-theory measures were examined for differences between smokers and controls and correlations with nicotine dependence. Sex differences were examined in a priori regions of interest based on prior literature. Compared to nonsmokers, connector hubs in smokers emerged primarily in limbic (parahippocampus) and salience network (cingulate cortex) regions. In addition, global influence of the right insula and left nucleus accumbens was associated with higher nicotine dependence. These trends were present in male but not female smokers. Network communication was altered in smokers, primarily in limbic and salience network regions. Network topology was associated with nicotine dependence in male but not female smokers in regions associated with reinforcement (nucleus accumbens) and craving (insula), consistent with the idea that male smokers are more sensitive to the reinforcing aspects of nicotine than female smokers. Identifying alterations in brain network communication in male and female smokers can help tailor future behavioral and pharmacological smoking interventions. Male smokers showed alterations in brain networks associated with the reinforcing effects of nicotine more so than females, suggesting that pharmacotherapies targeting reinforcement and craving may be more efficacious in male smokers.
Cigarette continuity programs and social support for smoking.

To describe smokers' participation in cigarette continuity programs and the prevalence and structure of cooperative teams of smokers. Cross-sectional survey of smoking histories and continuity-program participation by individuals and their family members in a convenience sample of 176 current smokers at the University of Kentucky Chandler Medical Center, Lexington. Fisher exact test or chi2 tests were used to compare proportions. One of 3 smokers collected coupons for a continuity program. Three quarters of the collectors redeemed their own coupons, and one quarter gave coupons to another collector. Coupon collectors reported an average team size of more than 2 members. One fifth of collectors were teammates with another generation of family members, and one quarter of collectors aged 24 to 35 years were teammates with their children. Smokers were often aware of their relatives' coupon-collecting habits. Continuity programs have been a popular means of reinforcing smoking, especially within families and groups of friends. Continuity programs are novel in encouraging smoking and brand loyalty between generations. Continuity-program participants need to be aware of the risk of promoting smoking initiation by their children. Health advocates could use similar strategies to promote smoking cessation and prevention within families and other social groups.

Cigarette smoking is a major cause of chronic obstructive pulmonary disease, (COPD) but many persons with COPD continue to smoke. Quitting can help prevent the development of and complications from COPD. This study examined whether smoking and cessation behaviors differed among adults with a) COPD, b) asthma, c) other chronic conditions only, or d) no chronic conditions. Smoking and chronic disease status was obtained from 488,909 adults aged > 18 years using the Behavioral Risk Factor Surveillance System; 9,476 current smokers and recent quitters in 5 states responded to additional questions about cessation. We computed age-adjusted prevalence of smoking and past-year quit attempts, and used bivariate and multivariable logistic regression to identify correlates of past-year quit attempts. Similar to the overall sample, in the 5-state sample, 47.3% of adults with COPD were current smokers versus 23.1% of those with asthma, 28.8% of adults with other chronic conditions, and 20.0% of those with no chronic conditions. Those with COPD did not differ significantly from those with asthma, other chronic diseases, or no chronic disease in having made a past-year quit attempt (59.7% versus 64.0%, 61.5%, and 53.9%, respectively). Smokers with COPD were significantly more likely than those with no chronic disease to have used cessation treatment resources, including a quitline, counseling, or medication (p < 0.001). Adults with COPD were just as likely as those without COPD to make a past-year quit attempt; however, approximately 40% of smokers with COPD did not try to quit.

Objective Early age at menopause is associated with increased risk of cardiovascular disease, stroke, osteoporosis and all-cause mortality. Cigarette smoke exposure in adulthood is an established risk factor for earlier age at natural menopause and may be related to age at menopausal transition. Using data from two U.S. birth cohorts, we examined the association between smoke exposure at various stages of the life course (prenatal, childhood exposure to parental smoking and adult smoke exposure) with menopause status in 1,001 women aged 39 – 49 years at follow-up. Methods We used logistic regression analysis, adjusting for age at follow-up, to estimate odds ratios (ORs) and 95% confidence intervals (CI) relating smoke exposure to natural menopause and menopausal transition. Results The magnitudes of the associations for natural menopause were similar, but not statistically significant after adjustment for confounders for i) women with prenatal smoke exposure who did not smoke at adult follow-up (OR= 2.7 [95% CI 0.8, 9.4]) and ii) current adult smokers who were not exposed prenatally (OR= 2.8 [95% CI 0.9, 9.0]). Women who had been exposed to prenatal smoke and were current smokers had three times the risk of experiencing natural menopause (adjusted OR=3.4 [95% CI 1.1, 10.3]) compared to women without smoke exposure in either time period. Only current smoking of long duration (>26 years) was associated with the timing of the menopausal transition. Conclusion Our data suggest that exposure to smoke both prenatally and around the time of menopause accelerates ovarian aging. PMID:25803667

Cigarette smoke exposure in adulthood is an established risk factor for earlier age at natural menopause and may be related to age at the menopausal transition. Using data from two US birth cohorts, we examined the association between smoke exposure at various stages of the life course (prenatal exposure, childhood exposure to parental smoking, and adult smoke exposure) and menopause status in 1,001 women aged 39 to 49 years at follow-up. We used logistic regression analysis (adjusting for age at follow-up) to estimate odds ratios (ORs) and 95% confidence intervals (CI) relating smoke exposure to natural menopause and the menopausal transition. The magnitudes of the associations for natural menopause were similar but not statistically significant after adjustment for confounders among (i) women with prenatal smoke exposure who did not smoke on adult follow-up (OR, 2.7; 95% CI, 0.8-9.4) and (ii) current adult smokers who were not exposed prenatally (OR, 2.8; 95% CI, 0.9-9.0). Women who had been exposed to prenatal smoke and were current smokers had three times the risk of experiencing earlier natural menopause (adjusted OR, 3.4; 95% CI, 1.1-10.3) compared with women without smoke exposure in either period. Only current smoking of long duration (>26 y) was associated with the timing of the menopausal transition. Our data suggest that exposure to smoke both prenatally and around the time of menopause accelerates ovarian aging.

Omega3 polyunsaturated fatty acids (PUFAs) are related to several diseases, including smoking. The aim of this study was to evaluate the relationship between omega-3 intake and tobacco smoking, taking into account the qualitative differences in dietary intake between smokers and non-smokers, the amount of the ingested PUFA and their red blood (RBC) contents. We also looked for an association between omega-3 RBC content and smoking, and also between omega3 intake and the level of nicotine dependence. Using a cross-sectional study, we included 50 current smokers (group I) and 50 lifetime non-smokers (group II), aged 18-75 years. We screened them at the Toronto Western Hospital and the Centre for Addiction and Mental Health (Toronto, Canada). The subjects completed a questionnaire with demographic data, lifestyle habits and details of food intake. The PUFAs measured in the RBC membranes were alphalinolenic acid, eicosapentaenoic acid (EPA), docosapentaenoic acid and docosahexaenoic acid (DHA). In order to perform an adjusted comparison between smokers and non-smokers we used the ANCOVA model. After adjusting for confounding factors, non-smokers showed higher consumption of PUFAs, especially salmon: 800 g (0-7.740) than smokers 430 g (0-2.150) P < 0.001. They also had higher DHA levels compared to smokers: 4.81% (2.79-10.21) and 4.13% (2.33-7.73), respectively, p < 0.05. The other PUFAs showed no significant differences between the two groups. Smokers ate less fish rich in omega3 fatty acids than non-smokers, showing and inverse and significant relationship between omega3 intake and smoking. Smokers had lower levels of DHA and EPA, a not previously reported finding. Considering that PUFAs probably interfere in smoking habit, the increase in omega-3 consumption may become a perspective in prevention or treatment of smoking. However, this inference must be evaluated through specific studies.

The aim of this study was to evaluate the differences, in terms of visual outcome and treatment needs, between smokers and non-smokers central serous chorioretinopathy (CSCR) patients. The files of 252 patients diagnosed with CSCR who had presented to the Retina Unit of the Ophthalmology Clinic at Dicle University Medical School in Turkey were retrospectively evaluated. Eighty-four smokers, with a known history of smoking of at least one pack-year, and 133 non-smokers were included, whereas 35 patients with additional pathologies were excluded from the study. Of the patients, 192 (88.5%) were male and 25 (11.5%) were female. The mean patient age was 38.8 ± 8.1 years (range: 20-68 years). Visual acuity (VA) of the smoker and non-smoker groups was measured as 0.45 ± 0.35 and 0.24 ± 0.28 logarithm of the minimum angle of resolution (logMar), respectively, at the first visit; 0.19 ± 0.29 and 0.06 ± 0.14 logMar at the sixth month; and 0.07 ± 0.14 and 0.02 ± 0.05 logMar at the ninth month. VA measurements at presentation and during all examinations (1th, 6th and 9th month) were significantly different for the two groups. VA was lower in the smoker group. In 27 patients (12.4%), an additional treatment modality was needed. Of the 27 patients, only 8 (6%) were non-smokers, whereas 19 (22.6%) were smokers. There was no difference between groups in the recurrence rate during follow-up (p = 0.907); 14 (16.7%) smokers and 8 (19.0%) non-smokers experienced a recurrence. This study has shown that patients selected and who are current smokers have poorer vision and need longer treatment.

BACKGROUND: Published predicted values for total lung capacity and residual volume are often based on a small number of subjects and derive from different populations from predicted spirometric values. Equations from the only two large studies gave smaller predicted values for total lung capacity than the smaller studies. A large number of subjects have been studied from a population which has already provided predicted values for spirometry and transfer factor for carbon monoxide. METHODS: Total lung capacity was measured from standard posteroanterior and lateral chest radiographs and forced vital capacity by spirometry in a population sample of 771 subjects. Prediction equations were developed for total lung capacity (TLC), residual volume (RV) and RV/TLC in two groups--normal and total. Subjects with signs or symptoms of cardiopulmonary disease were combined with the normal subjects and equations for all subjects were also modelled. RESULTS: Prediction equations for TLC and RV in non-smoking normal men and women were square root transformations which included height and weight but not age. They included a coefficient for duration of smoking in current smokers. The predictive equation for RV/TLC included weight, age, age and duration of smoking for current smokers and ex-smokers of both sexes. For the total population the equations took the same form but the height coefficients and constants were slightly different. CONCLUSION: These population based prediction equations for TLC, RV and RV/TLC provide reference standards in a population that has provided reference standards for spirometry and single breath transfer factor for carbon monoxide.

Indices of mood, mood regulation expectancies and everyday executive functioning were examined in adult current smokers and never-smokers of both genders in Australia (N = 97), where anti-smoking campaigns have dramatically reduced smoking prevalence and acceptability, and in China (N = 222), where smoking prevalence and public acceptance of smoking remain high. Dependent measures included the Depression Anxiety Stress Scales (DASS-21), the Negative Mood Regulation (NMR) expectancies scale, the Frontal Systems Behavior Scale (FrSBe), the Fagerström Test for Nicotine Dependence (FTND) and the Alcohol Use Disorders Identification Test (AUDIT). Multivariate analyses of covariance (MANCOVAs) controlling for demographic and recruitment related variables revealed highly significant differences between current smokers and never-smokers in both countries such that smokers indicated worse moods and poorer functioning than never-smokers on all dependent measures. Chinese smokers scored significantly worse on all dependent measures than Australian smokers whereas Chinese and Australian never-smokers did not differ on any of the same measures. Although nicotine dependence level as measured by FTND was significantly higher in Chinese than Australian smokers and was significantly correlated with all other dependent measures, inclusion of FTND scores as another covariate in MANCOVA did not eliminate the highly significant differences between Chinese and Australian smokers. Results are interpreted in light of the relative ease of taking up and continuing smoking in China compared to Australia today. © 2013 Elsevier Ltd. All rights reserved.

2002-01-01
Objective: To investigate differences in snuff consumption, sociodemographic and psychosocial characteristics between baseline intermittent smokers that had become daily smokers, stopped smoking or remained intermittent smokers at the one year follow up. Design/setting/participants/measurements: A population of 12 507 individuals interviewed at baseline in 1992-94 and at a one year follow up, aged 45–69 years, was investigated in a longitudinal study. The three groups of baseline intermittent smokers were compared to the reference population (all others) according to sociodemographic, psychosocial, and snuff consumption characteristics. A multivariate logistic regression model was used to assess differences in psychosocial conditions, adjusting for age, sex, country of origin, marital status, education, and snuff consumption. Results: 60% of all baseline intermittent smokers had remained intermittent smokers, 16% had become daily smokers, and 24% had stopped smoking at the one year follow up. The long term intermittent smokers and those who had stopped smoking were young, unmarried, highly educated, and snuff consumers to a higher extent than the reference population. They also had more psychosocial resources than the reference population, while the psychosocial resources of those who had become daily smokers were poorer. Conclusions: The majority of intermittent smokers are long term intermittent smokers. The results suggest that long term intermittent smokers have other psychosocial characteristics than daily smokers. PMID:11891370

Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for non-smokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine's vasoconstrictor effect.

The prevalence, correlates and reasons for using electronic cigarettes among New Zealand adults.
Li, Judy; Newcombe, Rhiannon; Walton, Darren
2015-06-01
There is strong interest in the use of electronic cigarettes (e-cigarettes) globally. This paper is the first to report population-based data on ever-use and current use of e-cigarettes among New Zealand adults. The paper also extends previous international studies by exploring the reasons for trying e-cigarettes, ever users' recall of brand(s) they have ever tried, and current users' recall of their current brand. The Health and Lifestyles Survey (HLS) is a biennial face-to-face in-house survey of New Zealand adults aged 15 years or over. In 2014, 2594 participants completed the survey. Ever-use and current use of e-cigarettes were 13.1% and 0.8% respectively. Tobacco smoking status predicted the use of e-cigarettes, with current smokers reporting the highest rate of use (50% ever-use and 4% current use). Among current smokers who had tried an e-cigarette, curiosity (49%) and desire to quit smoking (37%) were the most common reasons for trying. About half of the ever-users could not name any of the brand(s) they had ever tried, and one-fifth of current users could not name their current brand. Compared with other countries, New Zealand has a high rate of ever-use. Among current smokers, one in two had tried an e-cigarette. However, progression to regular use appears to be rare. The finding that 18% of current e-cigarette users could not name their current brand highlights the importance of investigating users' knowledge of e-cigarettes in general and assessing the factors that influence brand choice such as advertising, price, and accessibility.

Few studies have examined the individual and social impact of smoking behavior in the Japanese population. The purpose of this study was to clarify the association between smoking behavior and socio-demographic factors, lifestyle, mental health and work characteristics of Japanese civil servants. A self-administered questionnaire survey of 1,439 employees (821 men and 618 women) aged 20-64 yr was conducted in a local government department in 2001. The questionnaire included items on socio-demographic factors, education level, grade of employment, lifestyle, affect balance scale, and work characteristics. Smoking status was divided into current smoker, ex-smoker and never smoked. Multiple logistic regression analysis was performed to evaluate the relationship between smoking and the other items. Men presented a higher smoking prevalence rate than women (53.1% vs. 4.9%). In men, a strong relationship between current smoker and advanced age (40 yr or older), low education level, less physical activity, irregular breakfast and negative affect balance was found. Among men with a low education, the prevalence of smoking cessation was significantly lower in comparison to men with a high education. In women, being young (20-29 yr), unmarried (single or other), having a hobby, and irregular breakfast were associated with smoking behavior. Furthermore, smoking cessation was significantly associated with having a hobby and negative affect balance. The above results suggest that socio-demographic, lifestyle and mental health characteristics are independently associated with current smoking. These factors should be considered in smoking cessation policies as program components.

Few studies have examined the perceptions of risk of little cigar and cigarillo (LCC) smoking among cigarette smokers, which is important for expanding regulatory policies and developing prevention programs. We examined current cigarette smokers' perceived harm of LCC smoking, and determined whether these perceptions were associated with susceptibility and intention to continue smoking LCCs. Data were from the 2014 Tobacco Products and Risk Perceptions Survey of a probability sample of 5717 US adults. Data were analyzed for a subsample of 1191 current cigarette smokers who were stratified into three groups: (1) dual current cigarette smokers who had ever used LCCs, (2) current smokers susceptible to LCC smoking, and (3) current smokers who were not susceptible to LCC smoking. Overall, 47.2% of participants were dual smokers, 12.7% were susceptible to LCC smoking, and 40.1% were not susceptible. Perceptions of risk of LCCs varied across the groups. Dual smokers were more likely to perceive that daily LCC smoking is "very risky" (OR = 1.64, 95% CI = 1.08, 2.41) while occasional LCC smoking is only "somewhat risky" (OR = 1.71, 95% CI = 1.02, 2.87). Of the dual smokers, 20.7% intended to continue smoking LCCs in the future. Perceptions of addiction and risk of daily LCC smoking significantly predicted intention to continue LCC smoking. Addiction perceptions also significantly predicted susceptibility to initiate LCC smoking. Perceptions about harms from and addiction to LCCs could predict future LCC smoking. Health communication campaigns need to address the harms of LCCs. Our data suggest that perceptions of risk about the addictiveness of LCCs and frequency of use are important determinants of the LCC smoking susceptibility among some cigarette smokers and intended continued use among cigarette smokers with a history of LCC use. Health communication campaigns should address misperceptions related to LCCs. © The Author 2016. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco.

[Acceptance of a total smoking ban in schools: students' attitudes].
Morgenstern, M; Wiborg, G; Hanewinkel, R
2008-06-01
The purpose of this study was to measure students' attitudes towards a total smoking ban in schools and towards impositions in cases of violation. Cross-sectional survey of 1 738 students of 12 public schools in Schleswig-Holstein (grades 7-13, age 11-20 years). Data were collected by means of written questionnaires administered during class time. The following variables were assessed: attitude towards smoking ban, attitude towards impositions, age, sex, citizenship, perceived school climate, current smoking, lifetime smoking; for smokers, and additionally, the "Heaviness of Smoking Index". 76.5% of all students agreed with a total smoking ban, 66.4% agreed with the punishment of violations. Higher acceptance rates were found among girls, young students (11-15 years of age), for never-smokers, and for students who feel comfortable at school. Acceptance of the smoking ban is closely related to current smoking status: 93% of the non-smoking students, but only 14% of the daily smoking students agreed with the regulations. Refusal of the ban increased with increasing physical dependence. The intensification of the smoking ban in public schools meets approval by the majority of students. Smoking students should be more strongly involved in the implementation process, e.g., by supplemental cessation programmes.

Smoking rates are higher among those living at or below poverty and among persons with lower levels of education. We report on a formative research project examining patient perceptions of tobacco cessation strategies among diverse, low socioeconomic, urban smokers cared for in community-based primary care medical offices. We conducted 10 focus groups among low socioeconomic status participants recruited from urban primary care medical offices in Buffalo and Niagara Falls, New York. Participants included current or former smokers, who were stratified by age-group (18-39 years and 40+ years). The focus groups discussed perceptions of tobacco cessation strategies, previous quit attempts, and use/attitudes regarding technology and social media as potential platforms for cessation support. Participants (n = 96) included predominantly African Americans (n = 62, 65%) and European Americans (n = 16, 16%); 56% were older than 40 years and 92% were low income. Most participants were supportive of cessation message delivery via phone; however, the age-groups varied in their attitudes on quitting smoking, desired frequency of phone contacts, and social media usage. Participants aged 18 to 39 years reported more Internet use, greater use of text messaging, and were more open to health information via social media. Based on significant variation between younger and older smokers' perceptions of tobacco addiction and use of communication technologies, it appears reasonable to stratify the content and platform of health messaging by the target age-group.

This study investigated the prevalence of smoking, alcohol consumption, and physical activity in cancer survivors and examined the sociodemographic factors affecting these health-related behaviors.We used data from the 4th and 5th Korean National Health and Nutrition Examination Survey conducted between 2007 and 2012, which identified 1153 cancer cases and 36,451 people without a history of cancer ≥20 years of age. We used a structured questionnaire to obtain information concerning cancer diagnosis, health-related behaviors, and sociodemographic characteristics.The proportion of cancer survivors who were current drinkers, heavy drinkers, current smokers, or engaged in physical activity were 49.1, 9.0, 9.2, or 50.7%, respectively. Compared with people with no history of cancer, cancer survivors were less likely to be current drinkers (odds ratio [OR] = 0.45; 95% confidence interval [CI] 0.36-0.56), heavy drinkers (OR = 0.53; 95% CI 0.36-0.78), current smokers (OR = 0.37; 95% CI 0.24-0.55), or physically inactive (OR = 0.77; 95% CI 0.63-0.95). Cancer survivors with higher household incomes had higher odds of current drinking and heavy drinking (P trend = 0.039 and 0.033, respectively) and were less likely to be current smokers or physically inactive (P trend = 0.016 and 0.046, respectively). Age, sex, sites of cancer, and the time since diagnosis affected the health behaviors in cancer survivors. Furthermore, we confirmed that these unhealthy behaviors are interrelated.We found that household income had a bidirectional effect on health behaviors and confirmed an aggregation of unhealthy lifestyles. Identification of survivors vulnerable to unhealthy lifestyles, focusing on household income level would allow intervention programs to be more effective.
Country-level correlates of e-cigarette use in the European Union.
La Torre, Giuseppe; Mipatrini, Daniele
2016-03-01
The aim of this study was to assess the relationship between the prevalence of e-cigarette use and country-level factors across 28 European countries. The study objectives were addressed in an ecological design in which both exposures and outcomes were measured at the country level. Data from the Eurobarometer Report, the Eurostat database and the WHO observatory were analyzed. Bivariate and multivariate analyses were performed considering the rates of current and ever smokers of e-cigarettes as dependent variables, and socio-economic factors, health status and policies against tobacco as independent variables. Both the rate of current smokers and ever smokers of e-cigarette were positively associated to the offer of help to quit tobacco use (P < 0.01; P = 0.04) and to the raise of taxes on tobacco (P = 0.01; P = 0.01). The warn on dangers of tobacco negatively correlated with the rate of e-cigarette current smokers. The rate of current e-cigarette smokers correlated with the rate of current smokers and with national Gross Domestic Product, while the rate of ever e-cigarette smokers did not correlate with any socio-economic factor. Our analysis suggests that both policy and non-policy factors are associated with the geographical variability seen in the prevalence of e-cigarette use. Policies against the consumption of conventional tobacco products may lead to an increase of e-cigarette smokers.

In spite of the importance of a multifactorial approach to preventing cardiovascular disease in smokers, most information on the combined adverse effects of smoking and hypertension or high serum cholesterol on cardiovascular disease has been derived from Western populations, and coronary heart disease was often used as the only endpoint. Therefore, the present large-scale pooled analysis attempted to provide reliable information on the adverse effects of the coexistence of smoking and hypertension or high serum cholesterol on the risk of mortality from coronary heart disease and stroke in both, individuals and the entire population in Japan. A total of 27,385 male and 39,207 female participants aged 40-89 years were enrolled from 10 well-qualified Japanese cohort studies with a mean follow-up of 10.1 years. Hazard ratios and their corresponding 95% confidence intervals in smokers who had hypertension or high serum cholesterol were estimated for men and women separately using a Cox proportional hazards regression model that included age, body mass index, cohort and either serum total cholesterol or systolic blood pressure as covariates. Fractions of deaths attributable to the coexistence of these risk factors were also calculated. The multivariate-adjusted hazard ratios in male and female current smokers with hypertension, compared with those with neither factor were 2.57 (95% confidence intervals, 1.51-4.38) and 6.14 (3.49-10.79) for coronary heart disease, and 3.28 (1.89-5.71) and 1.61 (0.81-3.18) for cerebral infarction, respectively. The fractions of deaths attributable to the coexistence of current smoking and hypertension in men and women were 24.6 and 9.6% for coronary heart disease and 28.1 and 2.0% for cerebral infarction, respectively. Smokers with high serum cholesterol were broadly comparable to hypertensive smokers only with respect to coronary mortality risk; the hazard ratios, compared with those with neither factor were 4.19 (2.33-7.53) for men and 3.90 (1.57-9.67) for women. The fraction of coronary deaths attributable to the coexistence of current smoking and high serum cholesterol was 6.3% in men and 2.2% in women. There was no interaction between smoking habit and blood pressure or serum total cholesterol for these two subtypes in both men and women. Particular attention should be given to smokers who have concomitant hypertension or high serum cholesterol for preventing deaths due to cardiovascular disease. From a public health perspective in Japan, priority should be given to hypertensive smokers, since this group makes a large contribution to the burden of both coronary and cerebral infarction deaths.

The prevalence of smoking habits in severe obesity is higher than in the general population. There is some evidence that smokers have different temperaments compared to non-smokers. The aim of this study is to evaluate the associations between smoking status (smokers, ex-smokers and non-smokers) and temperament characteristics in bariatric surgery candidates. We analyzed data on temperament of 420 bariatric surgery candidates, as assessed by the AFECTS scale, in an exploratory cross-sectional survey of bariatric surgery candidates who have been grouped into smokers, ex-smokers and non-smokers. We detected significant statistical differences in temperament related to the smoking status in this population after controlling the current use of psychiatric medication. Smokers had higher anxiety and lower control than non-smokers. Ex-smokers with BMI >50 kg/m(2) presented higher coping and control characteristics than smokers. Smoking in bariatric surgery candidates was associated with lower control and higher anxious temperament, when controlled by current use of psychiatric medication. Smokers with BMI >50 kg/m(2) presented lower coping and control than ex-smokers. Assessment of temperament in bariatric surgery candidates may help in decisions about smoking cessation treatment and prevention of smoking relapse after surgery.

To assess the salivary composition of proteins and minerals in smokers compared with non-smokers. In this study we compared the total protein and Ca, Na, K, Mg, Pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years. Fifty-nine participants were evaluated. The mean age was 33.14±5.32 years among smokers and 32.15±5.12 years among non-smokers (P>0.05). The mean concentration of total protein, Ca, Pb, and Zn of whole saliva in smokers was lower than that in non-smokers, but the difference was not statistically significant (P>0.05). The mean concentration of Na, K, Mg in whole saliva was not significantly different between smokers and non-smokers (P>0.05). We specified that smoking reduced the value of total protein, Ca and Pb of saliva, however it did not have an impact on Na, K, and Mg of saliva.

Drinking alcohol and smoking tobacco are major modifiable risk factors for cancer. However, little is known about whether these modifiable factors of cancer survivors are associated with subsequent primary cancer (SPC) incidence, regardless of the first cancer sites. 27,762 eligible cancer survivors diagnosed between 1985 and 2007 were investigated for SPC until the end of 2008, using hospital-based and population-based cancer registries. The association between drinking, smoking and combined drinking and smoking (interaction) at the time of the first cancer diagnosis and incidence of SPCs (i.e., all SPCs, alcohol-related, smoking-related and specific SPCs) was estimated by Poisson regression. Compared with never-drinker/never-smoker, the categories ever-drinker/ever-smoker, current-drinker/current-smoker and heavy-drinker/heavy-smoker had 43-108%, 51-126% and 167-299% higher risk for all, alcohol-related and tobacco-related SPCs, respectively. The interaction of drinking and smoking had significantly high incidence rate ratios (IRRs) for SPCs among ever-drinker/ever-smoker and current-drinker/current-smoker, although ever drinking did not show a significant risk. Ever-drinker/ever-smoker had also significantly higher IRRs for esophageal and lung SPCs than never-drinker/never-smoker. Among comprehensive cancer survivors, ever and current drinkers only had a SPC risk when combined with smoking, while ever and current smokers had a SPC risk regardless of drinking status. Heavy drinking and heavy smoking were considered to be independent additive SPC risk factors. To reduce SPC incidence, it may be necessary (i) to reduce or stop alcohol use, (ii) to stop tobacco smoking and (iii) dual users, especially heavy users, should be treated as a high-risk population for behavioral-change intervention. © 2015 UICC.

Reduced availability of tobacco outlets is hypothesized to reduce smoking, but longitudinal evidence on this issue is scarce. To examine whether changes in distance from home to tobacco outlet are associated with changes in smoking behaviors. The data from 2 prospective cohort studies included geocoded residential addresses, addresses of tobacco outlets, and responses to smoking surveys in 2008 and 2012 (the Finnish Public Sector [FPS] study, n = 53 755) or 2003 and 2012 (the Health and Social Support [HeSSup] study, n = 11 924). All participants were smokers or ex-smokers at baseline. We used logistic regression in between-individual analyses and conditional logistic regression in case-crossover design analyses to examine change in walking distance from home to the nearest tobacco outlet as a predictor of quitting smoking in smokers and smoking relapse in ex-smokers. Study-specific estimates were pooled using fixed-effect meta-analysis. Walking distance from home to the nearest tobacco outlet. Quitting smoking and smoking relapse as indicated by self-reported current and previous smoking at baseline and follow-up. Overall, 20 729 men and women (age range 18-75 years) were recruited. Of the 6259 and 2090 baseline current smokers, 1744 (28%) and 818 (39%) quit, and of the 8959 and 3421 baseline ex-smokers, 617 (7%) and 205 (6%) relapsed in the FPS and HeSSup studies, respectively. Among the baseline smokers, a 500-m increase in distance from home to the nearest tobacco outlet was associated with a 16% increase in odds of quitting smoking in the between-individual analysis (pooled odds ratio, 1.16; 95% CI, 1.05-1.28) and 57% increase in within-individual analysis (pooled odds ratio, 1.57; 95% CI, 1.32-1.86), after adjusting for changes in self-reported marital and working status, substantial worsening of financial situation, illness in the family, and own health status. Increase in distance to the nearest tobacco outlet was not associated with smoking relapse among the ex-smokers. These data suggest that increase in distance from home to the nearest tobacco outlet may increase quitting among smokers. No effect of change in distance on relapse in ex-smokers was observed.
Cigarette Smoking and the Development of Premenstrual Syndrome

Moderate to severe premenstrual syndrome (PMS) affects as many as 20% of premenopausal women. Although smoking may be more common in women with PMS, it is unknown whether smoking is involved in PMS etiology. In 1991–2001, the authors conducted a case-control study nested within the prospective Nurses’ Health Study II. Participants were US women aged 27–44 years and free of PMS at baseline, including 1,057 who developed PMS over 10 years and 1,968 reporting no diagnosis of PMS and only minimal menstrual symptoms during this time. Smoking at various ages was assessed by questionnaires. After adjustment for oral contraceptives and other factors, current smokers were 2.1 times as likely as never smokers to develop PMS over the next 2–4 years (95% confidence interval: 1.56, 2.83). Total pack-years and smoking during adolescence and young adulthood were also independently associated with a higher risk of PMS. For example, the relative risk for women who started smoking before age 15 years, compared with never smokers, was 2.53 (95% confidence interval: 1.70, 3.76). Results suggest that smoking, especially in adolescence and young adulthood, may increase risk of moderate to severe PMS. These findings may provide an additional incentive for young women to avoid cigarette smoking. PMID:18701443

Tobacco smoking is estimated to be the largest preventable cause of mortality in the USA, but little is known about the relationship between neighborhood social environment and current smoking behavior or how this may differ by population and geography. We investigate how neighborhood social cohesion and disorder are associated with smoking behavior among legal and unauthorized Brazilian migrant adults using data from the 2007 Harvard-UMASS Boston Metropolitan Immigrant Health and Legal Status Survey (BM-IHLSS), a probabilistic household survey of adult Brazilian migrants. We employ logistic regression to estimate associations between neighborhood social cohesion, neighborhood disorder, and current smoking. We find that neighborhood-level social cohesion is associated with lower likelihood of being a current smoker (O.R. = .836; p < .05), and neighborhood disorder, measured as crime experienced in the neighborhood, is not associated with current smoking. Neighborhood population density, age, being male, and residing with someone who smokes are each positively associated with current smoking (p < .10). The health of participants' parents at the age of 35, being married, and individual earnings are associated with a reduction in the probability of being a current smoker (p < .05). Migrant legal status and length of residence in the USA are not associated with current smoking. Our findings suggest that neighborhood social cohesion may be protective against smoking. Alternatively, neighborhood disorder does not appear to be related to current smoking among Brazilian migrants.

Objectives Little is known about cigarette pricing and brand loyalty in sub-Saharan Africa. This study examines these issues in Zambia, analyzing data from the International Tobacco Control (ITC) Zambia Survey. Methods Data from Wave 1 of the ITC Zambia Survey (2012) were analyzed for current smokers of factory-made (FM) cigarettes compared to those who smoked both FM and roll-your-own (RYO) cigarettes, using multivariate logistic regression models to identify the predictors of brand loyalty and reasons for brand choice. Results 75% of FM-only smokers and 64% of FM+RYO smokers reported having a regular brand. Compared with FM-only smokers, FM+RYO smokers were, on average, older (28% vs. 20% ≥ 40 years), low income (64% vs. 43%), and had lower education (76% vs. 44% < secondary). Mean price across FM brands was ZMW0.50 (USD0.08) per stick. Smokers were significantly less likely to be brand-loyal (>1 year) if they were aged 15-17 years (vs. 40-54 years) and if they had moderate (vs. low) income. Brand choice was predicted mostly by friends, taste, and brand popularity. Price was more likely to be a reason for brand loyalty among FM+RYO smokers, among ≥55 year old smokers, and among those who reported being more addicted to cigarettes. Conclusions These results in Zambia document the high levels of brand loyalty in a market where price variation is fairly small across cigarette brands. Future research is needed on longitudinal trends to evaluate the effect of tobacco control policies in Zambia. PMID:25631482

Background Cigarette smoking is a risk factor of coronary heart disease (CHD). Vascular calcification such as coronary artery calcium (CAC) and aortic calcium (AC) is associated with CHD. We hypothesized that cigarette smoking is associated with coronary artery and aortic calcifications in Japanese and Koreans with high smoking prevalence. Methods Random samples from populations of 313 Japanese and 302 Korean men aged 40 to 49 were examined for calcification of the coronary artery and aorta using electron beam computed tomography. Coronary artery calcium (CAC) and aortic calcium (AC) were quantified using the Agatston score. We examined the associations of cigarette smoking with CAC and AC after adjusting for conventional risk factors and alcohol consumption. Current and past smokers were combined and categorized into two groups using median pack-years as a cutoff point in each of Japanese and Koreans. The never smoker group was used as a reference for the multiple logistic regression analyses. Results The odds ratios of CAC (score ≥10) for smokers with higher pack-years were 2.9 in Japanese (P<0.05) and 1.3 in Koreans (non-significant) compared to never smokers. The odds ratios of AC (score ≥100) for smokers with higher pack-years were 10.4 in Japanese (P<0.05) and 3.6 in Koreans (P<0.05). Conclusion Cigarette smoking with higher pack-years is significantly associated with CAC and AC in Japanese men, while cigarette smoking with higher pack-years is significantly associated with AC but not significantly with CAC in Korean men.

Electronic cigarettes (e-cigarettes) are battery-operated nicotine-delivery devices used by some smokers as a cessation tool as well as by never smokers. To determine the usage of e-cigarettes in older adults at risk for or with chronic obstructive pulmonary disease (COPD). Prospective cohorts. COPDGene (N = 3536) and SPIROMICS (N = 1060) subjects who were current or former smokers aged 45-80. Participants were surveyed to determine whether e-cigarette use was associated with longitudinal changes in COPD progression or smoking habits. From 2010 to 2016, participants who had ever used e-cigarettes steadily increased to 12-16%, but from 2014 to 2016 current use was stable at ~5%. E-cigarette use in African-Americans (AA) and whites was similar; however, AA were 1.8-2.9 times as likely to use menthol-flavored e-cigarettes. Current e-cigarette and conventional cigarette users had higher nicotine dependence and consumed more nicotine than those who smoked only conventional cigarettes. E-cigarette users had a heavier conventional cigarette smoking history and worse respiratory health, were less likely to reduce or quit conventional cigarette smoking, had higher nicotine dependence, and were more likely to report chronic bronchitis and exacerbations. Ever e-cigarette users had more rapid decline in lung function, but this trend did not persist after adjustment for persistent conventional cigarette smoking. E-cigarette use, which is common in adults with or at risk for COPD, was associated with worse pulmonary-related health outcomes, but not with cessation of smoking conventional cigarettes. Although this was an observational study, we find no evidence supporting the use of e-cigarettes as a harm reduction strategy among current smokers with or at risk for COPD.

The "meaningful use of certified electronic health record" policy requires eligible professionals to record smoking status for more than 50% of all individuals aged 13 years or older in 2011 to 2012. To explore whether the coding to document smoking behavior has increased over time and to assess the accuracy of smoking-related diagnosis and procedure codes in identifying previous and current smokers. We conducted an observational study with 5,423,880 enrollees from the year 2009 to 2014 in the Truven Health Analytics database. Temporal trends of smoking coding, sensitivity, specificity, positive predictive value, and negative predictive value were measured. The rate of coding of smoking behavior improved significantly by the end of the study period. The proportion of patients in the claims data recorded as current smokers increased 2.3-fold and the proportion of patients recorded as previous smokers increased 4-fold during the 6-year period. The sensitivity of each International Classification of Diseases, Ninth Revision, Clinical Modification code was generally less than 10%. The diagnosis code of tobacco use disorder (305.1X) was the most sensitive code (9.3%) for identifying smokers. The specificities of these codes and the Current Procedural Terminology codes were all more than 98%. A large improvement in the coding of current and previous smoking behavior has occurred since the inception of the meaningful use policy. Nevertheless, the use of diagnosis and procedure codes to identify smoking behavior in administrative data is still unreliable. This suggests that quality improvements toward medical coding on smoking behavior are needed to enhance the capability of claims data for smoking-related outcomes research.

E-cigarette use prevalence has increased drastically among young adult cigarette smokers in recent years. This study seeks to understand which e-cigarette flavors-sweet and fruity or tobacco and menthol/mint-are more likely to be associated with smoking reduction and cessation among young adults. Longitudinal data (waves 1 and 2) of the Population Assessment of Tobacco and Health (PATH) Study from young adult (aged 18-34) cigarette smokers (n = 4,645) at wave 1 and current e-cigarette users (n = 844) at wave 2 were used. Univariate and multivariate regressions were conducted to examine the associations between past-year smoking reduction and cessation and current e-cigarette flavor use at wave 2. At wave 2, 25.9% of respondents either reduced or quit smoking, and 6.7%, 5.2%, and 6.3% of them reported currently using e-cigarettes with tobacco/menthol (TM) flavors, one non-tobacco/non-menthol (NTM) flavor, and multiple NTM flavors, respectively. E-cigarette users with one (AOR = 2.5, p < 0.001) and multiple NTM flavors (AOR = 3.0, p < 0.001) were more likely to have reduced or quit smoking over the past year compared to non-e-cigarette users. NTM flavor use was positively associated with e-cigarette use of a higher frequency and larger amount. The positive association between past-year smoking reduction and cessation and current NTM flavored e-cigarette use may be explained by young adults' escalated e-cigarette use with NTM flavors. Public health professionals should prevent and reduce multiple tobacco use through enhanced education about the harm of vaping NTM flavors and by advising young adult smokers to quit tobacco altogether using evidence-based methods.

Tobacco use is a leading preventable risk factor for many chronic disorders, which are expected to account for an increasing share of the global disease burden. As part of the Global Youth Tobacco Survey (GYTS), we aimed to assess the effect of tobacco use by young people on global mortality. GYTS is a school-based survey of students aged 13-15 years. The survey was undertaken at 395 sites in 131 countries and the Gaza Strip and West Bank. We questioned students about current tobacco use, susceptibility to smoking among non-smokers, and exposure to secondhand smoke at home and in public places. The difference in current cigarette smoking between boys and girls is narrower than expected in many regions of the world. Use of tobacco products other than cigarettes by students is as high as cigarette smoking in many regions. Almost one in five never-smokers reported they were susceptible to smoking in the next year. Student exposure to secondhand smoke was high both at home (more than four in ten) and in public places (more than five in ten). Never-smokers were significantly less likely than current smokers to be exposed to secondhand smoke at home (prevalence 39.1% [95% CI 36.6-41.6] vs 72.8% [64.0-81.6]) and in public places (49.5% [46.7-52.3] vs 81.2% [74.2-88.2]). Our findings are troubling for the future of chronic disease and tobacco-related mortality. Reduction of tobacco consumption will require a redoubling of efforts to prevent initiation and promote cessation among the large proportion of young people who currently use tobacco. High exposure to secondhand smoke suggests a need for countries to pass strong and effective smoke-free policies.

Although previous studies indicate that people with lower intelligence quotient (IQ) scores are more likely to become cigarette smokers, IQ scores of siblings discordant for smoking and of adolescents who began smoking between ages 18-21 years have not been studied systematically. Each year a random sample of Israeli military recruits complete a smoking questionnaire. Cognitive functioning is assessed by the military using standardized tests equivalent to IQ. Of 20 221 18-year-old males, 28.5% reported smoking at least one cigarette a day (smokers). An unadjusted comparison found that smokers scored 0.41 effect sizes (ES, P < 0.001) lower than non-smokers; adjusted analyses remained significant (adjusted ES = 0.27, P < 0.001). Adolescents smoking one to five, six to 10, 11-20 and 21+ cigarettes/day had cognitive test scores 0.14, 0.22, 0.33 and 0.5 adjusted ES poorer than those of non-smokers (P < 0.001). Adolescents who did not smoke by age 18, and then began to smoke between ages 18-21 had lower cognitive test scores compared to never-smokers (adjusted ES = 0.14, P < 0.001). An analysis of brothers discordant for smoking found that smoking brothers had lower cognitive scores than non-smoking brothers (adjusted ES = 0.27; P = 0.014). Controlled analyses from this large population-based cohort of male adolescents indicate that IQ scores are lower in male adolescents who smoke compared to non-smokers and in brothers who smoke compared to their non-smoking brothers. The IQs of adolescents who began smoking between ages 18-21 are lower than those of non-smokers. Adolescents with poorer IQ scores might be targeted for programmes designed to prevent smoking.

There is an established link between smoking, abnormal heart rate (HR) values, and impaired cardiovascular health in middle-aged or older populations. The purpose of this study was to examine the effects of smoking on resting HR and on HR responses during and after exercise in young adults. A sample of 298 young adults (159 men), aged 20-29 years old, were selected from a large population of health-science students based on health status, body mass index, physical activity, and smoking habit. All subjects underwent a maximal Bruce treadmill test and their HR was recorded during, at peak, and after termination of exercise. Smokers had significantly higher resting HR values than non-smokers. Both female and male smokers showed a significantly slower HR increase during exercise. Female smokers failed to reach their age-predicted maximum HR by 6.0 bpm and males by 3.6 bpm. The actual maximum HR achieved (HRmax) was significantly lower for both female smokers (191.0 bpm vs.198.0 bpm) and male smokers (193.2 bpm vs.199.3 bpm), compared to non-smokers. Heart rate reserve was also significantly lower in female (114.6 bpm vs. 128.1 bpm) and male smokers (120.4 bpm vs. 133.0 bpm). During recovery, the HR decline was significantly attenuated, but only in female smokers. Females had a higher resting HR and showed a higher HR response during sub-maximal exercise compared to males. Smoking was found to affect young smokers' HR, increasing HR at rest, slowing HR increase during exercise and impairing their ability to reach the age-predicted HRmax. In addition, smoking was associated with an attenuated HR decline during recovery, but only in females.

Smoking remains the leading cause of preventable death in the United States. Although healthcare workers play a key role in helping patients quit smoking, the degree to which they provide help varies. This study assesses the extent to which smokers report that their healthcare worker advised and assisted them with quitting based on their level of readiness to make a change. The 2006 Hawaii Adult Tobacco Survey asked questions regarding smoking status and if advice and assistance with quitting was given from a healthcare worker. Percentages for reporting healthcare worker's advice and assistance were compared among the three levels of motivational readiness using the chi-square test of association for 331 current, everyday smokers (56% women; 38% in the age group of 45-54 years). Most smokers are given advice to quit smoking. However, only about half of those motivated to quit are given assistance to do so. Most smokers across all motivation levels received advice to quit smoking with no significant difference between levels of readiness to quit. Less than half of smokers received any type of assistance with quitting smoking, with higher motivated smokers significantly receiving more assistance with cessation medication or nicotine replacement therapy and setting a quit date. This is a call to action for healthcare workers to address smoking with every patient. Adjustments to protocols for addressing smoking cessation and readiness to quit may be warranted.

Farmers are exposed to multiple air contaminants that may interact with tobacco smoking in the development of respiratory diseases. Farmers are currently considered to smoke less than non-farmers, but precise data in different categories of age and farming activities are lacking. Smoking habits were studied in a cross-sectional study involving 4105 farmers and 996 non-farming controls aged 40-74 years in 9 French departments between October 2012 and May 2013. Three age groups were defined (40-54, 55-64 and 65-74years). Farmers were divided into four activity groups, namely cattle breeders, livestock farmers working in confined spaces, crop farmers and others. Smoking prevalence was compared between farmers and controls, and odds ratios (ORs) for smoking adjusted for age were calculated. The adjusted OR for ever-smoking was lower among farmers than among non-farmers in all age categories, but the ORs for current smoking were similar in farmers and controls. Smoking prevalence varied according to the type of farming activity, and was lower than in non-farming controls only among cattle breeders and confined livestock farmers. In farmers, the proportion of smokers was higher in the youngest age categories compared with the older age classes. Our results confirm that the prevalence of ever-smokers is lower in farmers than in non-farmers. Nevertheless, our data show that active smoking prevalence is similar in farmers and in non-farmers. This suggests that farmers, just like non-farmers, should be targeted by primary prevention campaigns against smoking.
Parent and Child Cigarette Use: A Longitudinal, Multigenerational Study
Staff, Jeremy
2013-01-01
OBJECTIVES: Using longitudinal data from the multigenerational Youth Development Study (YDS), this article documents how parents’ long-term smoking trajectories are associated with adolescent children’s likelihood of smoking. Prospective data from the parents (from age 14–38 years) enable unique comparisons of the parents’ and children’s smoking behavior, as well as that of siblings. METHODS: Smoking trajectories are constructed using latent class analysis for the original YDS cohort (n = 1010). Multigenerational longitudinal data from 214 parents and 314 offspring ages 11 years and older are then analyzed by using logistic regression with cluster-corrected SEs. RESULTS: Four latent smoking trajectories emerged among the original cohort: stable nonsmokers (54%), early-onset light smokers who quit/reduce (16%), late-onset persistent smokers (14%), and early-onset persistent heavy smokers (16%). Although 8% of children of stable nonsmokers smoked in the last year, the other groups’ children had much higher percentages, ranging from 23% to 29%. Multivariate logistic regression models confirm that these significant differences were robust to the inclusion of myriad child- and parent-level measures (for which child age and grade point average [GPA] are significant predictors). Older sibling smoking, however, mediated the link between parental heavy smoking and child smoking. CONCLUSIONS: Even in an era of declining rates of teenage cigarette use in the United States, children of current and former smokers face an elevated risk of smoking. Prevention efforts to weaken intergenerational associations should consider parents’ long-term cigarette use, as well as the smoking behavior of older siblings in the household. PMID:23918887
[Changes in tobacco consumption: boom of roll-your-own cigarettes and emergence of e-cigarettes].
Tarrazo, Marina; Pérez-Ríos, Mónica; Santiago-Pérez, María I; Malvar, Alberto; Suanzes, Jorge; Hervada, Xurxo
To assess changes in smoking prevalence and study roll-your-own (RYO) tobacco and e-cigarette use in the Galician population between 2007 and 2015. Data were obtained from five independent, cross-sectional studies carried out in Galicia (Spain) between 2007-2015 in the population aged 16 and over (n=8,000/year). Prevalence of use was estimated, with 95% confidence intervals, overall, according to sex and by age group, area of residence and level of education. Smoking prevalence decreased from 25.4% in 2007 to 21.8% in 2015. In 2007, 1.8% of current smokers declared that they had smoked RYO tobacco, compared to 18.6% in 2015. Among smokers, RYO tobacco consumption increased across all demographic groups. In both 2014 and 2015, ever use of e-cigarettes was 0.7%. E-cigarette use was more frequent in urban settings. Smoking prevalence decreased in Galicia between 2007 and 2015, and there has been rapid growth in the prevalence of RYO tobacco use. Although smokers are more likely to use e-cigarettes, both former and never smokers declared their use. The boom of RYO cigarettes and the emergence of e-cigarettes highlight the importance of having continuous surveillance systems to identify smoking behavioural changes. Copyright © 2016 SESPAS.

2008-10-01
While African-American females are more likely to be light smokers compared to their counterparts of other racially classified social groups (RCSGs), they are more likely to carry a heavier burden of smoking-related morbidity and mortality. Thus, it is critical that African-American female light smokers are targeted to engage in smoking cessation. Research has revealed that African-American women are less likely to have a successful quit attempt following a cessation intervention than females from other RCSGs. It has been postulated that the low smoking cessation rates among African-American female light smokers may be due to the lack of appropriate psychosocioculturally tailored cessation interventions that address issues of stress and coping that explain why they smoke and continue to smoke that may differ from their heavy smoker counterparts. The purpose of this study was to ascertain whether African-American female light smokers differed from their heavy smoker counterparts on psychosociocultural stress and coping factors. Findings revealed no differences in the sociodemographic variables of age, income, education and BMI; in the psychosociocultural measures of acculturative stress, race-related stress and coping; or in the smoking characteristics of menthol smoking status, cotinine level and CYP2A6 metabolic functioning between light and heavy smokers. However, the study found that African-American female light smokers take longer to smoke their first cigarette of the day, have a lower smoking risk, are more likely to quit, and exhibit lower carbon monoxide levels than African-American female heavy smokers. The current study suggests that other than the obvious factors of greater likelihood of quitting, lower smoking risk, longer latency to smoke and lower carbon monoxide levels, specific smoking cessation programs may not need to be differentially psychosocio-culturally tailored for African-American female light smokers compared to their heavy-smoking counterparts.

Aims Although depression and smoking are highly correlated, the relationship of Major Depressive Disorder (MDD) to smoking cessation and relapse remains unclear. This study compared changes in smoking for current and former smokers with and without Current and Lifetime MDD over a three year period. Design Analysis of two waves of longitudinal data from the National Institute on Alcohol Abuse and Alcoholism’s National Epidemiologic Survey on Alcohol and Related Conditions (Wave 1, 2001–2002; Wave 2, 2004–2005). Setting Data were collected through face-to-face interviews from non-institutionalized United States civilians, 18 years and older, in 50 states and the District of Columbia. Participants 11,973 adults (46% female) classified as Current or Former Daily Smokers at Wave 1 and completed Wave 2. Measurements Classification as Current or Former Smokers at Wave 1 and Wave 2. Findings Smoking status remained stable for most participants. Wave 1 Current Daily Smokers with Current MDD (OR=1.38, 95% CI=1.03, 1.85) and Lifetime MDD (OR=1.48, 95% CI=1.18, 1.85) were more likely than those without the respective diagnosis to report continued smoking at Wave 2. Wave 1 Former Daily Smokers with Current MDD (OR=0.44, 95% CI=0.26, 0.76) were less likely to report continued abstinence at Wave 2. None of the gender by MDD diagnosis interactions were significant. Patterns of results remained similar when analyses were limited to smokers with nicotine dependence. Conclusions Current and Lifetime Major Depressive Disorder are associated with a lower likelihood of quitting smoking and Current Major Depressive Disorder is associated with greater likelihood of smoking relapse.

To evaluate state cigarette excise tax pass-through rates for selected price-minimizing strategies. Multivariate regression analysis of current smokers from a stratified, national, dual-frame telephone survey. United States. A total of 16 542 adult current smokers aged 18 years or older. Cigarette per pack prices paid with and without coupons were obtained for pack versus carton purchase, use of generic brands versus premium brands, and purchase from Indian reservations versus outside Indian reservations. The average per pack prices paid differed substantially by price-minimizing strategy. Smokers who used any type of price-minimizing strategies paid substantially less than those who did not use these strategies (P < 0.05). Premium brand users who purchased by pack in places outside Indian reservations paid the entire amount of the excise tax, together with an additional premium of 7-10 cents per pack for every $1 increase in excise tax (pass-through rate of 1.07-1.10, P < 0.05). In contrast, carton purchasers, generic brand users or those who were likely to make their purchases on Indian reservations paid only 30-83 cents per pack for every $1 tax increase (pass-through rate of 0.30-0.83, P < 0.05). Many smokers in the United States are able to avoid the full impact of state excise tax on cost of smoking by buying cartons, using generic brands and buying from Indian reservations. Published 2014.

To compare perceived reasons for continued smoking and withdrawal symptoms between current smokers and quitters in an inner-city adolescent population. To examine the relationship of nicotine dependence, stress, and coping methods between smokers and quitters and, using the Transtheoretical Model of Change, among adjacent smoking cessation stages. A cross-sectional study using a self-administered questionnaire. The study comprised 354 clinic patients between the ages of 12 and 21 years who reported past or present smoking. Demographic characteristics, smoking status, perceived reasons for continued smoking, attempts to quit, and withdrawal symptoms, as well as standardized scales assessing nicotine dependence, stress, and coping methods. The overall prevalence of smoking in this population was 26%. Smokers were significantly more likely to report smoking more cigarettes per day as well as higher levels of physical addiction (P<.01), greater levels of perceived stress (P<.02), and less use of cognitive coping methods (P<.02) than quitters (P<.005). However, comparison of consecutive stages revealed a significant difference only between precontemplation and contemplation in cognitive coping methods (P<.01). Three of 20 withdrawal symptoms (cravings, difficulty dealing with stress, and anger) were reported more frequently among current smokers who had attempted to quit in the last 6 months than among former smokers (P<.01). Interventions for inner-city adolescents who smoke should be designed to target those with the highest levels of nicotine dependence, stress, and decreased use of cognitive coping methods because they are the least likely to quit on their own, rather than developing stage-specific models.

Creative and innovative strategies to recruit smokers are essential for improving tobacco control activities. Currently in Brazil, through health warning messages on cigarette packs, there is a permanent and intense spread of messages that provoke feelings of loss associated with smoking, which is important to encourage access to smoking quitlines. The study analyzed the call rate for telephone counseling after introducing a new strategy for reactive recruitment focused on the theme 'smoking causes shortness of breath', adapted to the subway setting in Rio de Janeiro, as compared to the rates for two existing reactive strategies. Regardless of age bracket, there was a higher response to the new proposed strategy. Despite the major awareness-raising in Brazil concerning the ills of tobacco, new communications formats approaching personally relevant themes can increase the number and range of smokers recruited for telephone counseling to support cessation.
Modifiable risk factor levels of coronary heart disease survivors in a middle-aged workforce.
Metcalf, P A; Scragg, R K; Swinburn, B

Coronary heart disease (CHD) is common in New Zealand. Risk factors for CHD are modifiable or non-modifiable. Modifiable risk factor levels of CHD survivors were compared with those without such a history (non-CHD). Participants were from a cross-sectional survey of 5,656 workers aged > or = 40. CHD survivors were 73 general practitioner (GP)-confirmed participants with a history of hospitalisation for CHD. There were no significant differences in mean blood pressure levels between CHD survivors and non-CHD workers after adjusting for age, gender and ethnicity, but current use of antihypertensive medications was higher in CHD survivors (34.2%) than non-CHD workers (8.1%); p < 0.001. CHD survivors had higher, similarly adjusted, mean serum total cholesterol, triglyceride and lower HDL-cholesterol levels, and their reported carbohydrate, fibre, polyunsaturated fat intakes and ratio of polyunsaturated to saturated fat intakes were higher and total fat, saturated fat and monounsaturated fat intakes were lower. CHD survivors ate fewer servings of red meats per month and more servings of fruit, and cereal, and number of cups of milk. Salt added to meals was lower and margarine use higher in CHD survivors. There were no significant differences in the proportions of those who exercised regularly, or were current cigarette smokers. However, more CHD survivors (57.5%) than non-CHD workers (33.1%) were ex-smokers p < 0.001, who had stopped smoking at a higher mean (se) age (41.1 (1.36) vs 37.6 (0.20) years respectively; p = 0.012). A large proportion of CHD survivors were dyslipidaemic, despite consuming a lower fat, higher fibre and carbohydrate diet. More than 50% of CHD survivors were ex-cigarette smokers, who had given up smoking at a later age than non-CHD workers. These high-risk CHD survivors would benefit from more aggressive measures aimed at correcting their dyslipidaemias.

Background: As most smokers initiate smoking during adolescence, assessment of smoking motives that underlie trajectories of dependence is critical for both prevention and cessation efforts. In the current study, we expected participants with higher nicotine dependence would smoke (a) less for positive reinforcement (PR) and (b) more for negative reinforcement (NR) motives. We secondarily assessed the relative contribution of PR to NR motives across levels of dependence. Methods: Data were drawn from a study on cue-elicited craving among occasional versus daily adolescent smokers aged 16–20 years (N = 111). Smoking motives were assessed in relation to 3 commonly used measures of nicotine dependence: (a) Fagerström Test for Nicotine Dependence (FTND), (b) Autonomy over Smoking Scale (AUTOS), and (c) Nicotine Dependence Syndrome Scale (NDSS). Results: Compared to occasional smokers, daily smokers had significantly higher scores on each dependence measure and endorsed more prominent NR smoking motives. Each measure of nicotine dependence was strongly associated with NR motives for smoking, although measures differed in their association with PR motives. As expected, the FTND, AUTOS, and NDSS each significantly predicted smoking motive difference score (PR − NR), such that higher dependence was associated with more prominent NR motives for smoking. Conclusions: Results are consistent with our understanding of dependence and provide further support for 3 common measures of nicotine dependence among early stage smokers. PMID:24924155

Tobacco and cannabis are frequently used in combination and cannabis co-use may lead to poor tobacco cessation outcomes. Therefore, it is important to explore if cannabis co-use is associated with a reduced likelihood of achieving successful tobacco abstinence among treatment-seeking tobacco smokers. The present study examined whether current cannabis use moderated tobacco cessation outcomes after 12 weeks of pharmacological treatment (varenicline vs. nicotine patch vs. placebo) with adjunctive behavioral counseling. Treatment-seeking tobacco smokers (N = 1,246) were enrolled in an intent-to-treat study, of which 220 were current cannabis users. Individuals were randomly assigned to 12 weeks of placebo (placebo pill plus placebo patch), nicotine patch (active patch plus placebo pill), or varenicline (active pill plus placebo patch), plus behavioral counseling. The primary endpoint was biochemically verified 7-day point prevalence abstinence at the end of treatment. Controlling for rate of nicotine metabolism, treatment arm, age, sex, alcohol, and level of nicotine dependence, cannabis users were as successful at achieving biochemically verified 7-day point prevalence abstinence compared to tobacco-only smokers. Findings suggest that cannabis use does not hinder the ability to quit tobacco smoking. Future tobacco cessation studies should employ prospective, longitudinal designs investigating cannabis co-use over time and at different severity levels.

To examine attitudes toward tobacco control policies among older African American homeless-experienced smokers. A qualitative study. Oakland, California. Twenty-two African American older homeless-experienced smokers who were part of a longitudinal study on health and health-related outcomes (Health Outcomes of People Experiencing Homelessness in Older Middle Age Study). We conducted in-depth, semistructured interviews with each participant to explore beliefs and attitudes toward tobacco use and cessation, barriers to smoking cessation, and attitudes toward current tobacco control strategies including raising cigarette prices, smoke-free policies, and graphic warning labels. We used a grounded theory approach to analyze the transcripts. Community social norms supportive of cigarette smoking and co-use of tobacco with other illicit substances were strong motivators of initiation and maintenance of tobacco use. Self-reported barriers to cessation included nicotine dependence, the experience of being homeless, fatalistic attitudes toward smoking cessation, substance use, and exposure to tobacco industry marketing. While participants were cognizant of current tobacco control policies and interventions for cessation, they felt that they were not specific enough for African Americans experiencing homelessness. Participants expressed strong support for strategies that de-normalized tobacco use and advertised the harmful effects of tobacco. Older African American homeless-experienced smokers face significant barriers to smoking cessation. Interventions that advertise the harmful effects of tobacco may be effective in stimulating smoking cessation among this population.

Previous studies have shown that IgE levels vary according to factors such as age, gender and smoking but most studies have been small and none have been based on a nationally representative sample. To investigate the influence of epidemiological factors on serum total IgE and house dust mite-specific IgE levels. An interviewer-led questionnaire was carried out and blood samples taken from 24 952 people aged 11 and over as part of the 1995 and 1996 Health Surveys for England. Serum total IgE and house dust mite-specific IgE were measured. Both total and house dust mite-specific IgE were more frequently raised in men and in younger age groups. After adjusting for age and sex, raised total IgE was more common in current smokers and non-white ethnic groups and was not related to social class. The higher levels in non-white ethnic groups was not explained by smoking, urban living or being born outside the UK. Whilst total IgE levels declined in older age groups in non-smokers, among smokers they increased across successive age groups from 50 years onwards. In contrast, following adjustment for age and sex, raised house dust mite IgE was more common in non-manual workers and in some non-white ethnic groups but was not related to smoking. This large nationwide study provides further confirmation of differing epidemiological patterns for total serum IgE and allergen-specific sensitization. Indicative ranges for 'usual' values for a wide range of ages among men and women in England are given.

Given the high prevalence of young adult smoking, we examined (i) psychosocial factors and substance use among college students representing five smoking patterns and histories [non-smokers, quitters, native non-daily smokers (i.e. never daily smokers), converted non-daily smokers (i.e. former daily smokers) and daily smokers] and (ii) smoking category as it relates to readiness to quit among current smokers. Of the 4438 students at six Southeast colleges who completed an online survey, 69.7% (n = 3094) were non-smokers, 6.6% (n = 293) were quitters, 7.1% (n = 317) were native non-daily smokers, 6.4% (n = 283) were converted non-daily smokers and 10.2% (n = 451) were daily smokers. There were differences in sociodemographics, substance use (alcohol, marijuana, other tobacco products) in the past 30 days and psychosocial factors among these subgroups of students (P < 0.001). Among current smokers, there were differences in cigarettes smoked per day, recent quit attempts, self-identification as a smoker, self-efficacy and motivation to quit (P < 0.001). After controlling for important factors, converted non-daily smokers were more likely to be ready to quit in the next month versus native non-daily smokers (OR = 2.15, CI 1.32–3.49, P = 0.002). Understanding differences among young adults with different smoking patterns and histories is critical in developing interventions targeting psychosocial factors impacting cessation among this population.

Lung cancer is the leading cause of non-AIDS-defining cancer deaths among HIV-infected individuals. Although lung cancer screening with low-dose computed tomography (LDCT) is endorsed by multiple national organizations, whether HIV-infected individuals would have similar benefit as uninfected individuals from lung cancer screening is unknown. Our objective was to determine the benefits and harms of lung cancer screening among HIV-infected individuals. We modified an existing simulation model, the Lung Cancer Policy Model, for HIV-infected patients. Veterans Aging Cohort Study, Kaiser Permanente Northern California HIV Cohort, and medical literature. Target population: HIV-infected current and former smokers. Lifetime. Population. Annual LDCT screening from ages 45, 50, or 55 until ages 72 or 77 years. Benefits assessed included lung cancer mortality reduction and life-years gained; harms assessed included numbers of LDCT examinations, false-positive results, and overdiagnosed cases. For HIV-infected patients with CD4 at least 500 and 100% antiretroviral therapy adherence, screening using the Centers for Medicare & Medicaid Services criteria (age 55-77, 30 pack-years of smoking, current smoker or quit within 15 years of screening) would reduce lung cancer mortality by 18.9%, similar to the mortality reduction of uninfected individuals. Alternative screening strategies utilizing lower screening age and/or pack-years criteria increase mortality reduction, but require more LDCT examinations. Strategies assumed 100% screening adherence. Lung cancer screening reduces mortality in HIV-infected patients with CD4 at least l500, with a number of efficient strategies for eligibility, including the current Centers for Medicare & Medicaid Services criteria.

Compare the effect of parental and best friend smoking across the stages of adolescent smoking, from being a never smoker susceptible to smoking, to being a daily smoker National cross-sectional annual survey (2002-2006 combined) of 157,637 Year 10 students aged 14 and 15 years who answered an anonymous self-administered questionnaire. The effects of smoking by parents and best friend varied with stage of adolescent tobacco smoking. Attributable risk calculations showed that parental and best friend smoking explained only 6.3% of susceptibility to smoking among never smokers, and 21.7% of non-smoking students who had ever experimented with cigarettes. The attributable risk for parental and best friend smoking progressively increased with smoking frequency, up to 78.7% for daily smoking. The effect of best friend smoking was stronger than parental smoking, although there was a synergistic effect of both variables on the risk of daily smoking. Smoking by best friend and parents are strongly associated with current smoking by adolescents, but unrelated to susceptibility to smoke among those who are non-smokers.

E-cigarette use among Serbian adults: prevalence and user characteristics.
Kilibarda, Biljana; Mravcik, Viktor; Martens, Marcus Sebastian
2016-03-01
The objective was to report the prevalence and characteristics of electronic cigarette (e-cigarette) users in order to inform an appropriate response to this emerging challenge in tobacco control. Data were drawn from a cross-sectional survey conducted in 2014 that used computer-assisted interviewing in a representative sample of 5385 Serbian adults age 18-64 years. Lifetime e-cigarette use and current use was reported by 9.6 and 2 % of adults, respectively. Younger adults had a higher prevalence of both lifetime and current use. Females were more likely to be current e-cigarette users than males. The majority of ever and current e-cigarette users were current or past cigarette smokers, but lifetime use was reported by non-smokers as well. Electronic cigarettes are popular in Serbia; one in ten adults had tried them at least once. Because females and young adults were more likely to use e-cigarettes, a targeted response in these specific groups is needed. A standardised methodology for monitoring e-cigarette use should be established and surveys exploring motives for and attitudes towards e-cigarettes use should be conducted.

Tobacco smoke alters lung defense mechanisms against infections and so increases the risk of mycobacterium tuberculosis infection. To determine the particular clinical features of tuberculosis in smokers and identify risk factors. We conducted a prospective, cross-sectional study over a period of nine months in Dakar, Senegal. The Chi-square test and multiple logistic regression were used to identify differences between smokers and non-smokers and to identify factors associated with clinical outcomes. We included 165 patients with active pulmonary tuberculosis (59 smokers versus 106 never-smokers). The average age of smokers was 43.8±12.7 versus 32.1±13.1 years (P<0.0001). Smokers were overwhelmingly male (98.3% versus 1.8%, P<0.0001). The average delay to consultation was longer among smokers (90 days [30-120] versus 60 days [30-90] ; P<0.0001). In multivariate analysis, alcohol abuse, increasing age, male sex, and an unknown retroviral status were independent risk factors for pulmonary tuberculosis. Haemoptysis was observed more frequently in smokers (49.1% versus 31.1%, P=0.017). With regards to chest X-ray features, smokers presented with more advanced, bilateral and cavitating lung lesions. Diagnostic delay and haemoptysis are important characteristics of the pulmonary tuberculosis in tobacco smokers. Copyright © 2017 SPLF. Published by Elsevier Masson SAS. All rights reserved.

In smokers without airflow obstruction, detailed, objective and controlled quantification of the level of physical inactivity in daily life has never been performed. This study aimed to objectively assess the level of physical activity in daily life in adult smokers without airflow obstruction in comparison with matched non-smokers, and to investigate the determinants for daily physical activity in smokers. Sixty smokers (aged 50 (39-54) years) and 50 non-smokers (aged 48 (40-53) years) matched for gender, age, anthropometric characteristics, educational level, employment status and seasons of the year assessment period were cross-sectionally assessed regarding their daily physical activity with a step counter, besides assessment of lung function, functional exercise capacity, quality of life, anxiety, depression, self-reported comorbidities carbon monoxide level, nicotine dependence and smoking habits. When compared with non-smokers, smokers walked less in daily life (7923 ± 3558 vs 9553 ± 3637 steps/day, respectively), presented worse lung function, functional exercise capacity, quality of life, anxiety and depression. Multiple regression analyses identified functional exercise capacity, Borg fatigue, self-reported motivation/physical activity behaviour and cardiac disease as significant determinants of number of steps/day in smokers (partial r(2) = 0.10, 0.12, 0.16 and 0.05; b = 15, -997, 1207 and -2330 steps/day, respectively; overall fit of the model R(2) = 0.38; P < 0.001). Adult smokers without airflow obstruction presented reduced level of daily physical activity. Functional exercise capacity, extended fatigue sensation, aspects of motivation/physical activity behaviour and self-reported cardiac disease are significant determinants of physical activity in daily life in smokers. © 2014 The Authors.

Compared to the majority of non-Hispanic white ("white") cigarette smokers, many African American smokers demonstrate a later age of initiation. The goal of the present study was to examine African American late-onset smoking (ie, regular smoking beginning at age 18 or later) and determine whether late-onset (vs. early-onset) smoking is protective in terms of quit rates and health outcomes. We used data from the National Survey of Midlife Development in the United States (MIDUS) because the wide age range of participants (20-75 at baseline) allowed the examination of smoking cessation and mortality incidence across the lifespan. Consistent with previous research, results indicated a later average age of smoking onset among African Americans, compared to whites. Disentangling effects of race from age-of-onset, we found that the cessation rate among late-onset African American smokers was 33%, whereas rates for early-onset African American smokers and early- and late-onset white smokers ranged from 52% to 57%. Finally, results showed that among white, low-socioeconomic status (SES) smokers, the hazard rate for mortality was greater among early- versus late-onset smokers; in contrast, among African American smokers (both low- and high-SES) hazard rates for mortality did not significantly differ among early- versus late-onset smokers. Although late (vs. early) smoking onset may be protective for whites, the present results suggest that late-onset may not be similarly protective for African Americans. Tobacco programs and regulatory policies focused on prevention should expand their perspective to include later ages of initiation, in order to avoid widening tobacco-related health disparities. This study indicates that late-onset smoking is not only the norm among African American adult smokers, but that late- versus early-onset smoking (ie, delaying onset) does not appear to afford any benefits for African Americans in terms of cessation or mortality. These results suggest that prevention and intervention efforts need to consider individual groups (not just overall averages) and that tobacco control efforts need to be targeted beyond the teenage years. Tobacco programs and regulatory policies focused on prevention should expand their perspective to include later ages of initiation, to avoid widening tobacco-related health disparities. © The Author 2016.

Introduction: Compared to the majority of non-Hispanic white (“white”) cigarette smokers, many African American smokers demonstrate a later age of initiation. The goal of the present study was to examine African American late-onset smoking (ie, regular smoking beginning at age 18 or later) and determine whether late-onset (vs. early-onset) smoking is protective in terms of quit rates and health outcomes. Methods: We used data from the National Survey of Midlife Development in the United States (MIDUS) because the wide age range of participants (20–75 at baseline) allowed the examination of smoking cessation and mortality incidence across the lifespan. Results: Consistent with previous research, results indicated a later average age of smoking onset among African Americans, compared to whites. Disentangling effects of race from age-of-onset, we found that the cessation rate among late-onset African American smokers was 33%, whereas rates for early-onset African American smokers and early- and late-onset white smokers ranged from 52% to 57%. Finally, results showed that among white, low-socioeconomic status (SES) smokers, the hazard rate for mortality was greater among early- versus late-onset smokers; in contrast, among African American smokers (both low- and high-SES) hazard rates for mortality did not significantly differ among early- versus late-onset smokers. Conclusions: Although late (vs. early) smoking onset may be protective for whites, the present results suggest that late-onset may not be similarly protective for African Americans. Tobacco programs and regulatory policies focused on prevention should expand their perspective to include later ages of initiation, in order to avoid widening tobacco-related health disparities.

We examined adult participation in tobacco industry direct marketing: receipt of direct mail and use of coupons and brand reward programs. Participation was highest for direct mail; participation in all 3 forms differed by gender, age, and race/ethnicity; current smokers, Whites, and persons aged 25 to 64 years reported greater participation. Although tobacco industry direct marketing may influence smoking initiation, its potential to increase consumption and impede cessation is unquestionable.
How smokers may react to cigarette taxes and price increases in Brazil: data from a national survey
2014-01-01
Background Despite being the third largest tobacco producer in the world, Brazil has developed a comprehensive tobacco control policy that includes a broad restriction on both advertising and smoking in indoor public places, compulsory pictorial warning labels, and a menthol cigarette ban. However, tax and pricing policies have been developed slowly and only very recently were stronger measures implemented. This study investigated the expected responses of smokers to hypothetical price increases in Brazil. Methods We analyzed smokers’ responses to hypothetical future price increases according to sociodemographic characteristics and smoking conditions in a multistage sample of Brazilian current cigarette smokers aged ≥14 years (n = 500). Logistic regression analysis was used to examine the relationship between possible responses and different predictors. Results In most subgroups investigated, smokers most frequently said they would react to a hypothetical price increase by taking up alternatives that might have a positive impact on health, i.e., they would “try to stop smoking” (52.3%) or “smoke fewer cigarettes” (46.8%). However, a considerable percentage responded that they would use alternatives that would reduce the effect of price increases, such as the same brand with lower cost (48.1%). After controlling for sex age group (14–19, 20–39, 40–59, and ≥60 years), schooling level (≥9 versus ≤9 years), number of cigarettes per day (>20 versus ≤20), and stage of change for smoking cessation (precontemplation, contemplation, and preparation), lower levels of dependence were positively associated with the response “I would try to stop smoking” (odds ratio [OR], 2.19). Young age was associated with “I would decrease the number of cigarettes” (OR, 3.44). A low schooling level was strongly associated with all responses. Conclusions Taxes and prices increases have great potential to stimulate cessation or reduction of cigarette consumption further among two important vulnerable populations of smokers in Brazil: young smokers and those of low educational level. The results from the present study also suggest that seeking illegal products may reduce the impact of increased taxes, but does not eliminate it. PMID:24712903

Cigarette smoking is a world-wide habit and an important risk factor for cancer. It was known that cigarette smoking can change the expression of circulating microRNAs (miRNAs) in healthy middle-aged adults. However, it remains unclear whether cigarette smoking can change the levels of circulating miRNAs in young healthy smokers and whether there are differences in cancer susceptibility for the two cases. In this study, the miRNA expression profiles of 28 smokers and 12 non-smokers were determined by Agilent human MicroRNA array. We further performed bioinformatics analysis for the differentially expressed miRNAs. The result showed that 35 miRNAs were differentially expressed. Among them, 24 miRNAs were up-regulated and 11 miRNAs were down-regulated in smokers. Functional enrichment analysis showed that the deregulated miRNAs are related to immune system and hormones regulation. Strikingly, the up-regulated miRNAs are mostly associated with hematologic cancers, such as lymphoma, leukemia. As a comparison, the up-regulated plasma miRNAs in middle-aged smokers are mostly associated with solid cancers, such as hepatocellular carcinoma and lung cancer, suggesting that smoking could have different influences on young adults and middle-aged adults. In a conclusion, we identified the circulating miRNAs deregulated by cigarette smoking and revealed that the age-dependent deregulated miRNAs tend to be mainly involved in different types of human cancers.

A group of thirty-eight women under age 70 who sustained vertebral compression fractures during minor trauma included more postmenopausal smokers than a group of 34 similar women with fractures resulting from major trauma and more than a group of 572 other women. Advanced idiopathic osteoporosis occurring before age 65 was found rarely among nonsmokers. The percent cortical area at the second metacarpal midpoint was measured in 103 white women aged 40 to 49 years, and 208 white women aged 60 to 69 years. In the younger group, no quantitative differences were demonstrated between bones of the obese and the nonobese or between smokers and nonsmokers. In contrast, among the older group, postmenopausal smokers exhibited much more bone loss than did nonsmokers (P less than .001), and nonobese women demonstrated much more bone loss than did obese women, this difference being most striking among smokers.

Objective: To assess the relation between demographic factors and film smoking stereotypes in adolescents and the potential influence of smoker stereotypes on smoking susceptibility. Design: A cross sectional questionnaire survey of school students (n = 3041) aged 12–13 and 16–17 years who were asked to describe the personal characteristics of female and male smokers in films. Setting: 15 primary or intermediate schools and 10 secondary schools in Auckland, New Zealand. Results: Appraisals of smokers in film were strongly influenced by age and sex with younger adolescents and males more likely to see female smokers as sexy, intelligent and healthy whereas older students and females more often appraised female smokers as stressed bored and depressed. Overall, image stereotypes (sexy, stylish) were more likely to be significantly associated with smoking susceptibility than emotional sensitivity stereotypes (stressed, depressed etc). Conclusions: Adolescents differ significantly in their appraisal of smokers in films; however, image based stereotypes, rather than emotional sensitivity stereotypes, are significantly associated with smoking susceptibility.

There is a dearth of studies regarding the influence of cigarette smoking on periodontal inflammatory conditions among patients with type 2 diabetes mellitus (T2DM). The aim of the present study is to assess periodontal inflammatory conditions among smokers and never-smokers with and without T2DM. One hundred individuals (50 patients with T2DM [25 smokers and 25 never-smokers] and 50 controls [25 smokers and 25 never-smokers]) were included. Information regarding age, sex, duration and daily frequency of smoking, duration and treatment of diabetes, and oral hygiene was recorded using a questionnaire. Periodontal parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD], clinical attachment loss [AL], and marginal bone loss [MBL]) were measured. Hemoglobin A1c (HbA1c) levels were also recorded. Mean age, monthly income status, and education levels were comparable among smokers and never-smokers with and without T2DM. Mean HbA1c levels were significantly higher among patients with T2DM (8.2% ± 0.1%) compared with controls (4.4% ± 0.3%) (P <0.05). Smokers in the control group were smoking significantly greater numbers of cigarettes (15.5 ± 2.5 cigarettes daily) compared with smokers with T2DM (6.2 ± 2.1 cigarettes daily) (P <0.05). Periodontal parameters were comparable among smokers and never-smokers with T2DM. Among controls, periodontal parameters (PI [P <0.05], AL [P <0.05], PD ≥4 mm [P <0.05], and MBL [P <0.05]) were significantly higher in smokers than never-smokers. Never-smokers with T2DM had worse periodontal status than smokers and never-smokers in the control group (P <0.05). Periodontal inflammatory conditions are comparable among smokers and never-smokers with T2DM. Among controls, periodontal inflammation is worse among smokers than never-smokers.

Introduction The long-term risk of smoking in diabetic patients with stable ischemic heart disease (SIHD) is unknown. We sought to analyze the impact of smoking on outcomes of diabetic patients with SIHD when other cardiovascular risk factors are being aggressively treated. Methods The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial randomized 2368 diabetics with SIHD to intensive medical therapy (IMT) with prompt revascularization or IMT alone. Smoking status was obtained at baseline, 6 months, and 1, 2, 3, 4 and 5 years. The primary endpoint of interest was all-cause mortality. Results Of 2360 patients, 33.1% of patients never smoked, 54.4% were former smokers, and 12.5% were current smokers. The rate of all-cause mortality was greater for current (2.5 deaths/100 patient-years) and former smokers (3.1 deaths/100 patient-years) than never smokers (2.1 deaths/100 patient-years) (P = 0.007). Cardiac death, cardiovascular death, fatal or nonfatal myocardial infarction, and fatal or nonfatal stroke were not increased in current or former smokers compared with never smokers. Compared with never smokers, current smokers experienced a 49% increased hazard of death (Hazard Ratio (HR) 1.49, 95% Confidence Interval (CI): 0.97-2.29, P = 0.07) whereas former smokers had a 37% increased hazard of death (HR 1.37, 95% CI: 1.04-2.79, P = 0.02) when considering smoking status as a time-dependent variable and adjusting for factors that differed by smoking status. Conclusions Current and former smoking are associated with increased all-cause mortality in diabetics with SIHD but not with increased cardiovascular morbidity or mortality.

The aim of the present study was to examine the associations of current smoking with five other unhealthy lifestyle behaviors among urban civil servants in Japan according to sex and occupational category. The study included 10,232 urban civil servants in Japan who presented for a health check-up in 2011. We analyzed data on anthropometric measurements and self-reported lifestyle factors. Current smokers had a higher BMI than never smokers in white-collar workers, but not in blue-collar workers of both sexes. There were strong associations of current smoking with irregular breakfasting regardless of sex and occupational category. In males, current smokers were less likely to take exercise than ex-smokers in both occupational categories. The associations of current smoking with other unhealthy behaviors were modified by sex and occupational category. These results are useful for understanding the health risks among smokers according to sex and occupational category.

Objective Few longitudinal studies have examined the effect of tobacco price increase on both cessation among smokers and relapse among quitters. Our objective was to investigate the differential impact of the tobacco price increase on the changes in smoking status in the total population and various subgroups. Methods We analysed data from a Japanese nationally representative longitudinal study of 30 773 individuals aged 50–59 years (weighted sum of discrete-time number = 215 411) with smoking information, using inverse probability weighting to account for non-response at follow-up. Generalised estimating equation models were used to calculate the odds ratios (ORs) for smoking behavioural changes (cessation among smokers and relapse among quitters), using discrete-time design. Stratified analyses were conducted according to demographic, socioeconomic and health behavioural characteristics. Results From 2005 to 2012, current smoker prevalence among the middle-aged Japanese population decreased from 30.5% to 24.3%. Of all the factors surveyed, only the tobacco price increase in 2010 (up by 37%, the highest increase during the period) was significantly associated with both cessation among smokers (OR 2.14, 95% confidence interval 1.90 to 2.41) and prevention of relapse among quitters (0.60, 0.46 to 0.77). Regarding the subgroup analysis, the tobacco price increase was associated with a significant reduction in relapse in the lowest income, recent quitters and very poor health subgroups. However, different associations were observed for cessation; a significant association between price increase and cessation was observed among all subgroups except for the heavy smoker and recently unemployed subgroups. Conclusions We confirmed that the tobacco price rise was associated with increasing cessation and decreasing relapse concurrently. Furthermore, this price rise was associated with favourable smoking changes in nearly all population subgroups; a large differential impact was not observed across the various subgroups.

Background National smoking-specific lung cancer mortality rates are unavailable, and studies presenting estimates are limited, particularly by histology. This hinders interpretation. We attempted to rectify this by deriving estimates indirectly, combining data from national rates and epidemiological studies. Methods We estimated study-specific absolute mortality rates and variances by histology and smoking habit (never/ever/current/former) based on relative risk estimates derived from studies published in the 20th century, coupled with WHO mortality data for age 70–74 for the relevant country and period. Studies with populations grossly unrepresentative nationally were excluded. 70–74 was chosen based on analyses of large cohort studies presenting rates by smoking and age. Variations by sex, period and region were assessed by meta-analysis and meta-regression. Results 148 studies provided estimates (Europe 59, America 54, China 22, other Asia 13), 54 providing estimates by histology (squamous cell carcinoma, adenocarcinoma). For all smoking habits and lung cancer types, mortality rates were higher in males, the excess less evident for never smokers. Never smoker rates were clearly highest in China, and showed some increasing time trend, particularly for adenocarcinoma. Ever smoker rates were higher in parts of Europe and America than in China, with the time trend very clear, especially for adenocarcinoma. Variations by time trend and continent were clear for current smokers (rates being higher in Europe and America than Asia), but less clear for former smokers. Models involving continent and trend explained much variability, but non-linearity was sometimes seen (with rates lower in 1991–99 than 1981–90), and there was regional variation within continent (with rates in Europe often high in UK and low in Scandinavia, and higher in North than South America). Conclusions The indirect method may be questioned, because of variations in definition of smoking and lung cancer type in the epidemiological database, changes over time in diagnosis of lung cancer types, lack of national representativeness of some studies, and regional variation in smoking misclassification. However, the results seem consistent with the literature, and provide additional information on variability by time and region, including evidence of a rise in never smoker adenocarcinoma rates relative to squamous cell carcinoma rates.

Background Expanding the information on determinants of smoking cessation is crucial for developing and implementing more effective tobacco control measures at the national as well as European levels. Data on smoking cessation and its social correlates among adults from middle-income countries of Central and Eastern Europe are still poorly reported in the literature. The aim of the study was to analyze the association of socio-demographic indicators with long term tobacco smoking cessation (quit smoking for at least one year prior to interview) among adults. Moreover, we evaluated motives for giving up smoking from former smokers. Methods Data on former as well as current smokers’ socio-demographic and smoking-related characteristics were derived from the Global Adult Tobacco Survey (GATS). GATS is a cross-sectional, nationally representative household survey implemented in Poland between 2009 and 2010. GATS collected data on a representative sample of 7,840 individuals including 1,206 individuals who met the criteria of long-term smoking cessation and 2,233 current smokers. Smoking cessation rate was calculated as the number of former smokers divided by the number of ever smokers. Logistic regression analyses were used to obtain odds ratios (ORs) and 95% confidence interval (CI) of the broad number of variables on successful cessation of smoking. Results Among females the quit rate was 30.4% compared to 37.9% in males (p < 0.01). Former smokers declared concerns about the health hazard of smoking (60.8%) and the high price of cigarettes (11.6%) as primary reasons for smoking cessation. Older age, high education attainment, awareness of smoking health consequences was associated with long-term quitting among both genders. Also employed males had over twice the probability of giving up smoking compared with unemployed, and being religious did not contribute to successful smoking cessation. Conclusion Results indicated that smoking cessation policies focused on younger age groups are vital for curbing tobacco epidemic in Poland and should become a public health main concern. There is also the need for interventions to raise awareness on smoking health risks and quitting benefits are crucial to increase cessation potential among adult smokers. Nevertheless further effort needs to be done to prevent smoking uptake. PMID:23173904

The strongest environmental factors identified for ulcerative colitis (UC) are cigarette smoking and appendectomy. However, most studies have been performed using case-controls from hospital-based populations. The purpose of this study was to compare the history of previous appendectomy and smoking habits in a group of patients with UC and a control group, followed by gastroenterologists in private practice. We performed a case control study in which 100 physicians recruited UC-patients and age and sex matched controls. Data were collected during a single visit. Based on a standardized questionnaire, UC patients and controls were divided into never, former or current smokers, and into subjects with or without a previous history of appendectomy. One hundred and ninety eight age- and sex-matched pairs of UC patients and controls were included. The prevalence of appendectomy in the UC-patients and control group was 12% and 46%, respectively. The pairwise-matched OR of ulcerative colitis for previous appendectomy was 0.10 (95% CI, 0.05-0.21) (P<0.0001). The OR for former and never smokers versus current smokers was 2.40 (95% CI 1.31-4.38) (P=0.004). In UC-patients, the OR of family history of UC compared with controls was 2.80 (95% CI, 1.01-7.77) (P=0.048). This case-control study confirmed a strong negative correlation between both appendectomy and tobacco smoking, and ulcerative colitis in patients followed-up by gastroenterological practitioners.

Younger adults are more likely to smoke and less likely to seek treatment than older smokers. They are also frequent users of communication technology. In the current study, we conducted focus groups to obtain feedback about preferences for a text message-based smoking cessation program from potential users. Participants (N = 21, M age = 25.6 years, age range = 20-33 years) were current or recently quit smokers (M cigarettes/day = 12.8) who used text messaging. Participants completed questionnaires and participated in a 2-hour focus group. Focus groups were conducted using an a priori semistructured interview guide to promote discussion of the content and functionality of the intervention. Major themes from analysis of the focus groups included support for the acceptability of a text-based cessation program, suggestions for a more technologically broad-based program, and adjustments to the program structure. Participants recommended including social networking functions, user control of program output through an online profile, and text message features to promote interaction with the system. Interestingly, many participants suggested the program should begin on individuals' identified quit day, challenging the procedures used in most cessation programs, which begin by preparing participants for a future quit date. Overall, younger adult smokers appear to be interested in participating in a smoking cessation program that uses text messages and web-based elements. Qualitative feedback regarding the perceived optimal features and structure of a technology-based intervention challenged traditional methods of implementing smoking cessation interventions and will inform the development of future programs.

We compared predicted life-time health-care costs for current, never and ex-smokers in Germany under the current set of tobacco control polices. We compared these economic consequences of the current situation with an alternative in which Germany were to implement more comprehensive tobacco control policies consistent with the World Health Organization (WHO) Framework Convention for Tobacco Control (FCTC) guidelines. German EstSmoke, an adapted version of the UK EstSmoke simulation model, applies the Markov modelling approach. Transition probabilities for (re-)currence of smoking-related diseases were calculated from large German disease-specific registries and the German Health Update (GEDA 2010). Estimations of both health-care costs and effect sizes of smoking cessation policies were taken from recent German studies and discounted at 3.5%/year. Germany. German population of prevalent current, never and ex-smokers in 2009. Life-time cost and outcomes in current, never and ex-smokers. If tobacco control policies are not strengthened, the German smoking population will incur €41.56 billion life-time excess costs compared with never smokers. Implementing tobacco control policies consistent with WHO FCTC guidelines would reduce the difference of life-time costs between current smokers and ex-smokers by at least €1.7 billion. Modelling suggests that the life-time healthcare costs of people in Germany who smoke are substantially greater than those of people who have never smoked. However, more comprehensive tobacco control policies could reduce health-care expenditures for current smokers by at least 4%. © 2017 Society for the Study of Addiction.

A clear, up-to-date picture of smoking prevalence and its determinants is needed to inform the development of an effective tobacco control policy in Ukraine, particularly given the way in which the tobacco industry has targeted post-Soviet countries since transition. A nationally representative household survey was undertaken in Ukraine in February 2000. Data were available on 1,590 individuals (response rate 72%). Fifty-seven percent of men and 10% of women were current smokers and an additional 21 and 7%, respectively, were ex-smokers. Smoking behavior has changed considerably over successive generations, with an increase in the proportion of women smoking and a reduction in the mean age at first smoking. Factors associated with smoking include young age, urban residence (among women), and material hardship, particularly unemployment. Involvement in social networks appears to reduce the probability of smoking. Smoking commonly occurs in public places and smokers differ from nonsmokers in their health beliefs about smoking. Levels of smoking among men are already high and among young women are increasing rapidly. Unless an effective tobacco policy response is developed to address the issues identified, tobacco will continue to make an increasingly large contribution to premature morbidity and mortality in Ukraine.

The presence of any age-related differences in gingival pigmentation associated with smoking, particularly in a young population, remains to be fully investigated. The purpose of this study was to determine the age-related differences in smoking gingival pigmentation. Gingival pigmentation was analyzed using the gingival melanosis record (GMR) and Hedin's classification with frontal oral photographs taken at 16 dental offices in Japan. Participants were categorized into 10-year age groups, and their baseline photographs were compared. In addition, to evaluate the effect of smoking cessation on gingival pigmentation, subjects were divided into a former smoker group (stopped smoking) and current smoker group. A total of 259 patients 19 to 79 years of age were analyzed. People in their 30s showed the most widespread gingival pigmentation. In addition, subjects in their 20s showed a weak effect of smoking cessation on gingival pigmentation. These findings suggested that the gingival pigmentation induced by smoking was more remarkable in young people than in middle-aged people. This information may be useful for anti-smoking education, especially among young populations with a high affinity for smoking.

Background: Cruciferous vegetables, a rich source of isothiocyanates, have been reported to lower the risk of several types of cancer, including lung cancer. However, evidence from prospective observations of populations with a relatively high intake of cruciferous vegetables is sparse. Objective: We investigated the association between cruciferous vegetable intake and lung cancer risk in a large-scale population-based prospective study in Japan. Methods: We studied 82,330 participants (38,663 men; 43,667 women) aged 45-74 y without a past history of cancer. Participants were asked to respond to a validated questionnaire that included 138 food items. The association between cruciferous vegetable intake and lung cancer incidence was assessed with the use of Cox proportional hazard regression analysis to estimate HRs and 95% CIs (with adjustments for potential confounding factors). Results: After 14.9 y of follow-up, a total of 1499 participants (1087 men; 412 women) were diagnosed with lung cancer. After deleting early-diagnosed cancer and adjusting for confounding factors, we observed a nonsignificant inverse trend between cruciferous vegetable intake and lung cancer risk in men in the highest compared with the lowest quartiles (multivariate HR: 0.85; 95% CI: 0.69, 1.06; P -trend = 0.13). Stratified analysis by smoking status revealed a significant inverse association between cruciferous vegetable intake and lung cancer risk among those who were never smokers and those who were past smokers after deleting lung cancer cases in the first 3 y of follow-up [multivariate HR for never smokers: 0.49 (95% CI: 0.27, 0.87; P -trend = 0.04); multivariate HR for past smokers: 0.59 (95% CI: 0.35, 0.99; P -trend = 0.10)]. No association was noted in men who were current smokers and women who were never smokers. Conclusion: This study suggests that cruciferous vegetable intake may be associated with a reduction in lung cancer risk among men who are currently nonsmokers. © 2017 American Society for Nutrition.

Emphysema is largely an under-diagnosed medical condition that can exist in smokers in the absence of airway obstruction. We aimed to determine the sensitivity and specificity of pulmonary function tests (PFTs) in assessing emphysema using quantitative CT scans as the reference standard. We enrolled 224 ever-smokers (current or former) over the age of 40. CT of thorax was used to quantify the low attenuation area (% emphysema), and to measure the standardized airway wall thickness. PFTs were used individually and in combination to predict their ability to discriminate radiographic emphysema. Significant emphysema (>7%) was detected in 122 (54%) subjects. Twenty six (21%) emphysema subjects had no evidence of airflow obstruction (FEV1/FVC ratio <70%), while all subjects with >23% emphysema showed airflow obstruction. The sensitivity and specificity of spirometry for detecting radiographic emphysema were 79% and 75%, respectively. Standardized airway wall thickness was increased in subjects with airflow obstruction, but did not correlate with emphysema severity. In this cohort of lifetime ever-smokers, PFTs alone were inadequate for diagnosing emphysema. Airway wall thickness quantified by CT morphometry was associated with airflow limitation, but not with emphysema indicating that the heterogeneous nature of lung disease in smokers may represent distinct phenotypes.

The study describes the prevalence of different forms of smoking, and the correlates of current smoking, by male students of King Faisal University, Saudi Arabia. A random sample of 1382 students at 9 colleges answered a self-administered questionnaire based on the Global Youth Tobacco Survey plus the modified Fagerström Test for Nicotine Dependence. The prevalence of current smoking was 28.1% (21.6% for cigarettes, 14.6% for waterpipe). Of current smokers, 41.4% were living in homes where others smoke and 17.0% initiated smoking below age 12 years. In logistic regression analysis older age, living away from home, smoking by family and close friends and exposure to tobacco promotion were predictors of current smoking status.

Objective Spending on cigarettes may deprive households of other items like food. The goal of this study was to examine the prevalence of and factors associated with this smoking-induced deprivation among adult smokers in China. Methods The data came from waves 1–3 of the International Tobacco Control (ITC) China Survey, conducted from 2006 to 2009 among urban adults aged 18 years or older in China. We focus on the samples of current smokers from six cities (N=7981). Smoking-induced deprivation was measured with the survey question, “In the last six months, have you spent money on cigarettes that you knew would be better spent on household essentials like food?” We examined whether sociodemographic factors, smoking intensity and price paid per pack of cigarettes were associated with smoking-induced deprivation using generalised estimating equations modelling. Findings 7.3% of smokers reported smoking-induced deprivation due to purchasing cigarettes. Low-income and middle-income smokers were more likely to have smoking-induced deprivation compared with high-income smokers (adjusted OR (AOR)=2.06, 95% CI 1.32 to 2.31; AOR=1.44, 95% CI 1.10 to 1.69); smokers living in Shenyang (AOR=1.68, 95% CI 1.25 to 2.24) and Yinchuan (AOR=2.50, 95% CI 1.89 to 3.32) were more likely to have smoking-induced deprivation compared with smokers living in Beijing. Retired smokers were less likely to have smoking-induced deprivation compared with employed smokers (AOR=0.67, 95% CI 0.52 to 0.87). There was no statistically significant relationship between smoking intensity, price paid per pack of cigarettes and smoking-induced deprivation. Conclusions Our findings indicate that certain groups of smokers in China acknowledge spending money on cigarettes that could be better spent on household essentials. Tobacco control policies that reduce smoking in China may improve household living standards by reducing smoking-induced deprivation. PMID:24827978

In the last decade Poland has successfully carried out effective anti-tobacco campaigns and introduced tobacco control legislation. This comprehensive strategy has focused on the general population and has led to a considerable decrease in tobacco consumption. Prisoners constitute a relatively small part of the entire Polish population and smoking habits in this group have been given little attention. The aim of the study was to assess the prevalence of cigarette smoking in Polish male prisoners, factors determining smoking in this group, prisoners' attitudes towards smoking cessation, and to evaluate prisoners' perception of different anti-tobacco measures. An anonymous questionnaire including personal, demographic and smoking data was distributed among 944 male inmates. Of these, 907 men aged between 17 and 62 years (mean 32.3 years) met the inclusion criteria of the study. For the comparison of proportions, a chi-square test was used with continuity correction whenever appropriate. In the entire group, 81% of the subjects were smokers, 12% - ex-smokers, and 7% - never smokers. Current smokers had significantly lower education level than non-smokers (p < 0.0001) and ever-smokers more frequently abused other psychoactive substances than never smokers (p < 0.0001). Stress was reported as an important factor in prompting smoking (77%). Forty-nine percent of daily smokers were aware of the adverse health consequences of smoking. The majority of smokers (75%) had attempted to quit smoking in the past. Forty percent of smoking prisoners considered an award for abstaining from cigarettes as the best means to limit the prevalence of smoking in prisons. The prevalence of cigarette smoking among Polish prisoners is high. However, a majority of smokers attempt to quit, and they should be encouraged and supported. Efforts to reduce cigarette smoking in prisons need to take into consideration the specific factors influencing smoking habits in prisons.

Little is known about cigarette pricing and brand loyalty in sub-Saharan Africa. This study examines these issues in Zambia, analysing data from the International Tobacco Control (ITC) Zambia Survey. Data from Wave 1 of the ITC Zambia Survey (2012) were analysed for current smokers of factory-made (FM) cigarettes compared with those who smoked both FM and roll-your-own (RYO) cigarettes, using multivariate logistic regression models to identify the predictors of brand loyalty and reasons for brand choice. 75% of FM-only smokers and 64% of FM+RYO smokers reported having a regular brand. Compared with FM-only smokers, FM+RYO smokers were, on average, older (28% vs 20% ≥40 years), low income (64% vs 43%) and had lower education (76% vs 44% < secondary). Mean price across FM brands was ZMW0.50 (US$0.08) per stick. Smokers were significantly less likely to be brand loyal (>1 year) if they were aged 15-17 years (vs 40-54 years) and if they had moderate (vs low) income. Brand choice was predicted mostly by friends, taste and brand popularity. Price was more likely to be a reason for brand loyalty among FM+RYO smokers, among ≥55-year-old smokers and among those who reported being more addicted to cigarettes. These results in Zambia document the high levels of brand loyalty in a market where price variation is fairly small across cigarette brands. Future research is needed on longitudinal trends to evaluate the effect of tobacco control policies in Zambia. Published by the BMJ Publishing Group Limited.

Tobacco causes many adverse health conditions and may alter the upper gastrointestinal (UGI) microbiome. However, the few studies that studied the association between tobacco use and the microbiome were small and underpowered. Therefore, we investigated the association between tobacco use and the UGI microbiome in Chinese men. We included 278 men who underwent esophageal cancer screening in Henan Province, China. Men were categorized as current, former, or never smokers from questionnaire data. UGI tract bacterial cells were characterized using the Human Oral Microbial Identification Microarray. Counts of unique bacterial species and genera estimated alpha diversity. For beta diversity, principal coordinate (PCoA) vectors were generated from an unweighted UniFrac distance matrix. Polytomous logistic regression models were used for most analyses. Of the 278 men in this study, 46.8% were current smokers and 12.6% were former smokers. Current smokers tended to have increased alpha diversity (mean 42.3 species) compared to never smokers (mean 38.9 species). For a 10 species increase, the odds ratio (OR) for current smoking was 1.29 (95% CI 1.04-1.62). Beta diversity was also associated with current smoking. The first two PCoA vectors were strongly associated with current smoking (PCoA1 OR 0.66; 95% CI 0.51-0.87; PCoA2 OR 0.73; 95% CI 0.56-0.95). Furthermore, Dialister invisus and Megasphaera micronuciformis were more commonly detected in current smokers than in never smokers. Current smoking was associated with both alpha and beta diversity in the UGI tract. Future work should consider how the UGI microbiome is associated with smoking-related diseases.
