Coordinated high-impact interventions and community-level changes in smoking behaviour norms effectively reduced prevalence of smoking among youth in many developed countries. Smoking trends among Jordanian adolescents are likely different than their Western counterparts and must be understood in the context of their daily lives to tailor interventions specifically for adolescents in this setting. Between 2008 and 2011, a school-based longitudinal study was conducted in Irbid, Jordan. All seventh-grade students in 19 randomly selected schools (of 60) were surveyed annually for 4 years. Outcomes of interest were time trends in smoking behaviour, age at initiation and change in frequency of smoking. Among 1781 participants, baseline prevalence of current smoking (cigarettes or waterpipe) for boys was 22.9% and 8.7% for girls. Prevalence of ever-smoking and current any smoking, cigarette smoking, waterpipe smoking and dual cigarette/waterpipe smoking was significantly higher in boys than girls each year (P < 0.001). Smoking prevalence increased every year after year 2 for current smoking (P < 0.05) across all methods (any, cigarette, waterpipe and dual). At all time points for both boys and girls, prevalence of waterpipe smoking was higher than that of cigarette smoking (P < 0.001). This study shows intensive smoking patterns at early ages among Jordanian youth in Irbid, characterized by a predominance of waterpipe smoking and steeper age-related increase in cigarette smoking. It also points to the possibility of waterpipe being the favourite method for introducing youth to tobacco, as well as being a vehicle for tobacco dependence and cigarette smoking.

Data from a 2-year study describe tobacco use trends, perceptions, and prevention effects for 1,281 5th and 6th graders enrolled in 12 randomly selected Washington State elementary schools. Youths were pretested, then randomly divided by school into skills, discussion, and control groups. Preventive intervention curriculums for the skills and discussion groups included age-relevant information on smoked and smokeless tobacco use, peer testimonials, debates, games, and homework. Youths in the skills group also learned communication and problem-solving methods for handling difficult situations around tobacco use. Following intervention, youths were posttested, then retested semiannually for 2 years. During the 2-year study, three-quarters of all smokers and nonusers and half of all smokeless tobacco users maintained their statuses. Only 10 percent of all smokers and 3 percent of all smokeless users quit their habits. One in six reported new tobacco use, one-third of smokers began using smokeless tobacco, and two-thirds of all smokeless users began smoking during the study. Most youths at final measurement perceived smokeless tobacco as less of a health risk than smoking. Nearly one in two of all smokeless users intended to smoke, and two-thirds were actually smoking at 24-month followup. Both smoked and smokeless tobacco use rates increased in all groups, and youths in the skills intervention group consistently showed the lowest rates relative to the other groups. These findings demonstrate the potential of skills intervention methods for lowering tobacco use rates among adolescents.

Objective To estimate the impact of trends in smoking and obesity prevalence on productivity loss among petrochemical employees from 1980 to 2009. Methods Smoking and obesity informations were collected during company physical examinations. Productivity loss was calculated as differential workdays lost between smokers and non-smokers, and obese and normal-weight employees. Results During 1980–2009, smoking prevalence decreased from 32% to 17%, while obesity prevalence increased from 14% to 42%. In 1982, lost productivity from obesity was an estimated 43 days/100 employees, and for smoking, 65 days/100 employees, but by 1987, workdays lost due to obesity exceeded that attributable to smoking. In 2007, workdays lost from obesity were 3.7 times higher than for smoking. Conclusions Owing to the increasing trend in obesity, the productivity impact on employers from obesity will continue to rise without effective measures supporting employee efforts to achieve healthy weight through sustainable lifestyle changes.

In developed countries, smoking spreads through society like an epidemic in which adults from higher socioeconomic groups are the first to adopt and earlier to quit smoking, and in which exists a lag in adoption of smoking between men and women. The objective of this study was to describe trends in daily and occasional smoking, to investigate association between smoking status and education, and to examine if the associations in 1990-2010 in Estonia fit the pattern predicted by the model of tobacco epidemic. The study was based on a 20-64-year-old subsample (n = 18740) of nationally representative postal cross-sectional surveys conducted every second year in Estonia during 1990-2010. Cigarette smoking and education were examined. χ2 test for trend was used to determine daily and occasional smoking trends over study years. Multinomial logistic regression model was used to test educational differences in daily and occasional smoking for every study year. Adjusted relative risk ratios (RRRs) with 95% confidence intervals were calculated. In 1990-2010, daily smoking varied largely between genders showing decreasing trend among men, but not among women. In 2010, one third of men and one fifth of women were daily smokers. Daily smoking was not clearly associated with education among men in 1990-1994 and among women in 1990-2000. Men revealed inverse relationship between daily smoking and education since 1996, but women since 2002. In 2010, compared to men and women with higher education, relative risk ratio of daily smoking was 2.92 (95% CI = 2.01-4.25) among men and 2.29 (95% CI = 1.65-3.17) among women with secondary education, but 4.98 (95% CI 3.12-7.94) among men and 6.62 (95% CI = 4.07-10.76) among women with basic education.In 1990-2010, occasional smoking was stable and similar (varying between 7-10%) among men and women, no association with education was found. Daily smoking patterns in Estonia fit the model of tobacco epidemic in developed countries

Maternal smoking is a key modifiable risk factor in preventing adverse pregnancy outcomes such as intrauterine growth restriction, preterm birth and stillbirth. This observational study examined annual trends of maternal smoking reported at the first prenatal visit in women who delivered in a large university maternity hospital for the 5 years 2011-2015. We examined clinical and sociodemographic data computerised routinely for women who presented for prenatal care at the hospital between 2011 and 2015. Multinomial logistic regression was used to determine the maternal characteristics, health behaviours and psychiatric history associated with smoking behaviours. Of the 42,509 women the mean age was 31.4 ± 5.5 years, mean Body Mass Index (BMI) was 25.6 ± 5.1 kg/m 2 , and 39.5% were nulliparas. Overall, 52.6% reported they had never smoked, 34.9% were ex-smokers, 10.5% smoked ≤10 cigarettes per day, 1.9% smoked ≥11 cigarettes per day and 0.1% smoked e-cigarettes. Between 2011 and 2015 the prevalence of maternal cigarette smoking decreased from 14.3 to 10.9% (P < 0.001). Smoking during pregnancy was most strongly associated with younger age, multiparity, unemployment, unplanned pregnancy, a history of psychiatric problems, alcohol intake and illicit drug usage. The number of women who reported smoking at the first prenatal visit decreased annually. Amongst women who continue to smoke during pregnancy, there is a clustering of adverse lifestyle behaviour and psychological problems that may need to be addressed if smoking cessation interventions are going to succeed in improving fetal programming.

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.

Although gastric cancer has declined dramatically in the US, the disease remains the second leading cause of cancer mortality worldwide. A better understanding of reasons for the decline can provide important insights into effective preventive strategies. We sought to estimate the contribution of risk factor trends on past and future intestinal-type noncardia gastric adenocarcinoma (NCGA) incidence. We developed a population-based microsimulation model of intestinal-type NCGA and calibrated it to US epidemiologic data on precancerous lesions and cancer. The model explicitly incorporated the impact of Helicobacter pylori and smoking on disease natural history, for which birth cohort-specific trends were derived from the National Health and Nutrition Examination Survey (NHANES) and National Health Interview Survey (NHIS). Between 1978 and 2008, the model estimated that intestinal-type NCGA incidence declined 60% from 11.0 to 4.4 per 100,000 men, <3% discrepancy from national statistics. H. pylori and smoking trends combined accounted for 47% (range = 30%-58%) of the observed decline. With no tobacco control, incidence would have declined only 56%, suggesting that lower smoking initiation and higher cessation rates observed after the 1960s accelerated the relative decline in cancer incidence by 7% (range = 0%-21%). With continued risk factor trends, incidence is projected to decline an additional 47% between 2008 and 2040, the majority of which will be attributable to H. pylori and smoking (81%; range = 61%-100%). Limitations include assuming all other risk factors influenced gastric carcinogenesis as one factor and restricting the analysis to men. Trends in modifiable risk factors explain a significant proportion of the decline of intestinal-type NCGA incidence in the US, and are projected to continue. Although past tobacco control efforts have hastened the decline, full benefits will take decades to be realized, and further discouragement of smoking and reduction of

Cigarette smoking risk-reducing beliefs are ideas that certain health promoting behaviors (e.g., exercise) may mitigate the risks associated with smoking. The objective of this study was to describe smoking risk-reducing beliefs and the belief that quitting can reduce the harmful effects of smoking among the U.S. adult population and the associations between these beliefs, current smoking status, and sociodemographics. Data were from the Health Information National Trends Survey 4 (HINTS 4) Cycles 3 and 4 (2013-2014; N=6862). Descriptive analyses were conducted to examine bivariate associations among the quit smoking belief, smoking risk-reducing beliefs, and covariates. Weighted ordinal logistic regression models examined the adjusted associations between smoking status and sociodemographics, with quit smoking belief and risk-reducing beliefs. Eighty-two percent of the population reported that quitting cigarette smoking can help reduce the harmful effects of smoking a lot: former smokers and individuals with higher educational attainment were more likely to endorse this belief than never smokers and those with lower educational attainment. Many people endorsed smoking risk-reducing beliefs about exercise (79.3%), fruits and vegetables (71.8%), vitamins (67.2%), and sleep (68.5%). Former smokers were less likely to subscribe to these beliefs than never smokers. Vulnerable populations who may be most at risk of smoking attributable morbidity and mortality were more likely to endorse risk-reducing beliefs. Future studies are needed to better understand how risk-reducing beliefs are formed and if modifying these beliefs may help to reduce cigarette smoking in the U.S. Published by Elsevier Inc.

IMPORTANCE Significant progress has been made in reducing the prevalence of tobacco use in the United States. However, tobacco cessation efforts have focused on the general population rather than individuals with mental illness, who demonstrate greater rates of tobacco use and nicotine dependence. OBJECTIVES To assess whether declines in tobacco use have been realized among individuals with mental illness and examine the association between mental health treatment and smoking cessation. DESIGN, SETTING, AND PARTICIPANTS Use of nationally representative surveys of noninstitutionalized US residents to compare trends in smoking rates between adults with and without mental illness and across multiple disorders (2004–2011 Medical Expenditure Panel Survey [MEPS]) and to compare rates of smoking cessation among adults with mental illness who did and did not receive mental health treatment (2009–2011 National Survey of Drug Use and Health [NSDUH]).The MEPS sample included 32 156 respondents with mental illness (operationalized as reporting severe psychological distress, probable depression, or receiving treatment for mental illness) and 133 113 without mental illness. The NSDUH sample included 14 057 lifetime smokers with mental illness. MAIN OUTCOME SAND MEASURES Current smoking status (primary analysis; MEPS sample) and smoking cessation, operationalized as a lifetime smoker who did not smoke in the last 30 days (secondary analysis; NSDUH sample). RESULTS Adjusted smoking rates declined significantly among individuals without mental illness (19.2% [95% CI, 18.7–19.7%] to 16.5% [95% CI, 16.0%–17.0%]; P < .001) but changed only slightly among those with mental illness (25.3% [95% CI, 24.2%–26.3%] to 24.9% [95% CI, 23.8%–26.0%]; P = .50), a significant difference in difference of 2.3% (95% CI, 0.7%–3.9%) (P = .005). Individuals with mental illness who received mental health treatment within the previous year were more likely to have quit smoking (37.2% [95% CI

Evidence from the USA and elsewhere has linked smoking depictions in movies with youth smoking initiation. Prior research has not focused on depictions in films produced in the Middle East, however. We reviewed the 10 most commercially successful Iranian films released each year over three decades (1982-2011) to determine trends in depictions of tobacco use over time. Each movie was reviewed in its entirety, and depictions of smoking were recorded and classified as direct (characters holding or using tobacco products) and indirect (tobacco products appearing in the frame, but not being used). Time trends in average duration of direct, indirect and total smoking depictions were analysed using linear regression and Cohen's κ coefficient. The mean duration of tobacco depictions in the most commercially successful Iranian films fluctuated yearly over the 3 decades, but with an overall significant upward trend (p<0.005). The proportion of movies depicting tobacco consumption during the three decades was 36% (1982-1991), 60% (1992-2001) and 74% (2002-2011), respectively. The average proportion of total movie time for these depictions (0.75%, 1.41%, 2.08%) increased significantly (p<0.005) over the 3 decades as did the average duration of smoking depictions,(39.1, 67 and 99.3 s, respectively, p<0.005). The significant increase in the proportion of movies depicting tobacco consumption and in the duration of smoking depictions over the past 30 years underscores the need for increased regulation of the Iranian film industry to minimise this important source of influence on tobacco initiation in young people.

Mentholated cigarettes are at least as dangerous to an individual's health as non-mentholated varieties. The addition of menthol to cigarettes reduces perceived harshness of smoke, which can facilitate initiation. Here, we examine correlates of menthol use, national trends in smoking menthol and non-menthol cigarettes, and brand preferences over time. We estimated menthol cigarette use during 2004-2010 using annual data on persons ≥12 years old from the National Surveys on Drug Use and Health. We adjusted self-reported menthol status for selected brands that were either exclusively menthol or non-menthol, based on sales data. Data were weighted to provide national estimates. Among cigarette smokers, menthol cigarette use was more common among 12-17 year olds (56.7%) and 18-25 year olds (45.0%) than among older persons (range 30.5% to 34.7%). In a multivariable analysis, menthol use was associated with being younger, female and of non-Caucasian race/ethnicity. Among all adolescents, the percentage who smoked non-menthol cigarettes decreased from 2004-2010, while menthol smoking rates remained constant; among all young adults, the percentage who smoked non-menthol cigarettes also declined, while menthol smoking rates increased. The use of Camel menthol and Marlboro menthol increased among adolescent and young adult smokers, particularly non-Hispanic Caucasians, during the study period. Young people are heavy consumers of mentholated cigarettes. Progress in reducing youth smoking has likely been attenuated by the sale and marketing of mentholated cigarettes, including emerging varieties of established youth brands. This study should inform the Food and Drug Administration regarding the potential public health impact of a menthol ban. Published by the BMJ Publishing Group Limited.

Clonal expansion of T-cell receptor beta gene segment in the retrocochlear lesions of EAE mice.

It has been reported that the T cell receptor V beta 8.2 (TcrbV8.2) gene segment is predominantly expressed in encephalomyelitic T cells responding to myelin basic protein (MBP) in experimental allergic encephalomyelitis (EAE) mice. We have demonstrated retrocochlear hearing loss in EAE mice in previous studies. Administration of a monoclonal antibody specific to the T cell receptor V beta 8 (TcrbV8) subfamily prevented both this type of hearing loss and the central nerve disease. In this study, we examined the role of the TcrbV8.2 gene segment in the retrocochlear lesions of EAE mice. A clonal expression of T cell receptor beta chain gene segment (TcrbV8.2-TcrbD2-TcrbJ2.7) was identified in the retrocochlear lesions. The TcrbV8.2 gene segment appears to recombine only with TcrbJ2.1 (32.1%) and TcrbJ2.7 (67.9%) gene segments. The TcrbJ2.7 gene segment has also been previously identified as the dominant TcrbJ gene in the lymph nodes of EAE mice. Only TcrbD2, with a length of 4 amino acids, was observed recombining with these TcrbV8.2 sequences. G and C nucleotides are predominantly expressed at the N regions between the V-D and D-J junctions. This dominant TcrbV gene segment (TcrbV8.2-TcrbD2-TcrbJ2.7) observed in the retrocochlear lesions has been identified in the MBP-specific T cells from the lymph nodes of EAE mice. These results suggest that a small subset of antigen-specific T cells migrate to, and expand at, the retrocochlear lesions, which leads to hearing loss.

This paper reports population-based secular trends in smoking prevalence and tobacco exposure among smokers. The Minnesota Heart Survey (MHS) assessed smoking in probability samples in the seven-county Minneapolis–St. Paul metropolitan area. Five surveys were conducted in 1980–1982, 1985–1987, 1990–1992, 1995–1997, and 2000–2002 using similar sampling strategies and consistent protocols. Participants were metropolitan area residents of Minnesota, aged 25–74 years, with the addition of 75–84-year-olds in the last three surveys. In men, age-adjusted self-reported prevalence of current smoking steadily declined from 32.9% in 1980–1982, to 23.0% in 1995–1997, and to 20.6% in 2000–2002. In women, self-reported smoking was 31.8% in 1980–1982, 18.5% in 1995–1997, and 19.5% in the latest survey. Age-adjusted self-reported quantity of cigarettes consumed among smokers declined over the same period. Changes from 1995–1997 to 2000–2002 were not significant. Compared with Whites, Black participants had higher levels of smoking and later onset of the decline in smoking prevalence. A decline in smoking prevalence seems to have leveled off or reversed between the two most recent survey periods (1995–1997 through 2000–2002). Focus on smoking cessation should continue, especially in the subpopulation that smokes more than the majority. PMID:18569756

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

Background Home smoking bans significantly reduce the likelihood of secondhand smoke exposure among children and non-smoking adults. The purpose of this study was to examine national trends in a) the adoption of home smoking bans; b) discrepancies in parental smoking ban reports; and c) household and parental correlates of home smoking bans among households with underage children from 1995 to 2007. Methods We used data from the 1995/1996, 1998/1999, 2001/2002, 2003 and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey to estimate prevalence rates and logistic regression models of parental smoking ban reports by survey period. Results Overall, the prevalence of a complete home smoking bans increased from 58.1% to 83.8% (p<0.01), while discrepancies in parental reports decreased from 12.5% to 4.6% (p<0.01) from 1995 to 2007. Households with single parent, low income, one or two current smokers, parents with less than a college education, or without infants were consistently less likely to report a home smoking ban over this period (p<0.05). Conclusion Despite general improvements in the adoption of home smoking bans and a reduction on parental discrepancies, disparities in the level of protection from secondhand smoke have persisted over time. Children living in households with single parents, low income, current smoker parents, less educated parents, or without infants are less likely to be protected by a home smoking ban. These groups are in need of interventions promoting the adoption of home smoking bans to reduce disparities in tobacco-related diseases. PMID:21813487

The impact of tobacco control policies on measures of smoking cessation behaviour has often been studied, yet there is little information on their precise magnitude and duration. This study aims to measure the magnitude and timing of the impact of Dutch tobacco control policies on the rate of searching for information on smoking cessation, using Google Trends search query data. An interrupted time series analysis was used to examine the effect of two types of policies (smoke-free legislation and reimbursement of smoking cessation support (SCS)) on Google searches for 'quit smoking'. Google Trends data were seasonally adjusted and analysed using autoregressive integrated moving average (ARIMA) modelling. Multiple effect periods were modelled as dummy variables and analysed simultaneously to examine the magnitude and duration of the effect of each intervention. The same analysis was repeated with Belgian search query data as a control group, since Belgium is the country most comparable to the Netherlands in terms of geography, language, history and culture. A significant increase in relative search volume (RSV) was found from one to four weeks (21-41%) after the introduction of the smoking ban in restaurants and bars in the Netherlands in 2008. The introduction of SCS reimbursement in 2011 was associated with a significant increase of RSV (16-22%) in the Netherlands after 3 to 52 weeks. The reintroduction of SCS in 2013 was associated with a significant increase of RSV (9-21%) in the Netherlands from 3 to 32 weeks after the intervention. No effects were found in the Belgian control group for the smoking ban and the reintroduction of SCS in 2013, but there was a significant increase in RSV shortly before and after the introduction of SCS in 2011. These findings suggest that these tobacco control policies have short-term or medium-term effects on the rate of searching for information on smoking cessation, and therefore potentially on smoking cessation rates.

To examine trends in cigarette smoking prevalence and intensity among petroleum industry employees over a 22-year period, from 1976 to 1997, and to evaluate the hypothesis that the (about 20%) lower lung cancer mortality, when compared with the general population, among these workers is due to lower average cigarette consumption. Self-reported smoking prevalence and intensity (number of cigarettes smoked per day) data were available from the Shell Health Surveillance System for approximately 5,400 employees in the 1970s, 11,000 in the 1980s, and 8,300 in the 1990s. Data were analyzed by gender, time period, and work status (production vs. staff). During the 22-year study period, smoking prevalence dropped significantly in this working population. When compared with the general US population, smoking prevalence trends were very similar. For the entire employee population, smoking prevalence was highest for women working in production (hourly) jobs. While smoking prevalence was higher among production employees than among staff employees, daily cigarette consumption was slightly lower. Cigarette consumption among Shell employees was similar to that in the US in the 1970s, but lower in the 1980s and 1990s. By applying smoking consumption data from the 1970s, the ratio of weighted lung cancer relative risks for Shell employees and the US general population was 0.98. In other words, the lung cancer mortality rate of refinery and petrochemical employees would be adjusted upward by 2% if one were to remove the influence of smoking consumption by Shell employees. Based on our data, it is unlikely that differences in smoking prevalence and intensity between refinery/petrochemical workers and the general population could account for the lower risk of lung cancer mortality reported in the literature.

Public health efforts to reduce the harms related to tobacco use currently include a significant emphasis on anti-smoking media campaigns. This paper provides (a) data on the overall extent of exposure to anti-smoking media among American youth from 1997 to 2001, (b) an appraisal of general youth reactions to such advertising, and (c) an examination of how exposure levels and reactions vary by socio-demographic characteristics. Data were obtained from the Monitoring the Future study, an ongoing nationwide study of youth. Data were collected each year from nationally representative separate and nonoverlapping school samples of 8th, 10th, and 12th grade students (N = 29,724; 24,639; and 12,138, respectively). Self-reported levels of recalled exposure to both electronic and print anti-smoking advertising were measured, as well as the judged impact and perceived exaggeration of such advertising. Data indicate that significant increases in overall exposure to anti-smoking advertising occurred over the study time period. These increases were associated with (a) increases in the self-reported likelihood that anti-smoking advertising diminished the probability of individual smoking behaviors, and (b) increases in the perceived level to which anti-smoking advertising exaggerates the risks associated with smoking. Further, these trends were significantly associated with various characteristics-most notably, ethnicity, smoking behaviors, and residence in a state with an ongoing tobacco-control program having a media component.

Background The impact of tobacco control policies on measures of smoking cessation behaviour has often been studied, yet there is little information on their precise magnitude and duration. This study aims to measure the magnitude and timing of the impact of Dutch tobacco control policies on the rate of searching for information on smoking cessation, using Google Trends search query data. Methods An interrupted time series analysis was used to examine the effect of two types of policies (smoke-free legislation and reimbursement of smoking cessation support (SCS)) on Google searches for ‘quit smoking’. Google Trends data were seasonally adjusted and analysed using autoregressive integrated moving average (ARIMA) modelling. Multiple effect periods were modelled as dummy variables and analysed simultaneously to examine the magnitude and duration of the effect of each intervention. The same analysis was repeated with Belgian search query data as a control group, since Belgium is the country most comparable to the Netherlands in terms of geography, language, history and culture. Results A significant increase in relative search volume (RSV) was found from one to four weeks (21–41%) after the introduction of the smoking ban in restaurants and bars in the Netherlands in 2008. The introduction of SCS reimbursement in 2011 was associated with a significant increase of RSV (16–22%) in the Netherlands after 3 to 52 weeks. The reintroduction of SCS in 2013 was associated with a significant increase of RSV (9–21%) in the Netherlands from 3 to 32 weeks after the intervention. No effects were found in the Belgian control group for the smoking ban and the reintroduction of SCS in 2013, but there was a significant increase in RSV shortly before and after the introduction of SCS in 2011. Conclusions These findings suggest that these tobacco control policies have short-term or medium-term effects on the rate of searching for information on smoking cessation, and therefore

Recent trends in children's exposure to second-hand smoke in England: cotinine evidence from the Health Survey for England.

To examine changes in children's exposure to second-hand tobacco smoke in England since 1998. Repeated cross-sectional surveys of the general population in England. The Health Survey for England. A total of 37 038 children participating in surveys from 1998 to 2012, 13 327 of whom were aged 4-15 years, had available cotinine and were confirmed non-smokers. The proportion of children with smoking parents; the proportion of children living in homes reported to be smoke-free; the proportion of children with undetectable concentrations of cotinine; linear and quadratic trend estimates of geometric mean cotinine across years. By 2012, 87.3% of children lived in a home that was smoke-free {97.2% [95% confidence interval (CI) = 95.9-98.1] when parents were non-smokers, 61.3% (95% CI = 55.5-66.8) when one or both parents smoked}. A total of 68.6% (95% CI = 64.3-72.6%) of children had undetectable cotinine in 2012, up from 14.3% (95% CI = 12.7-16.0%) in 1998. There was a highly significant linear trend across years (with a small but significant quadratic term) to declining geometric mean cotinine in all children from 0.52 ng/ml (95% CI = 0.48-0.57) in 1998 to 0.11 ng/ml (95% CI = 0.10-0.12) in 2012. Children from routine/manual backgrounds were more exposed, but experienced similar gains across years to those from non-manual backgrounds. In England, children's exposure to second-hand smoke has declined by 79% since 1998, with continuing progress since smoke-free legislation in 2007. An emerging social norm in England has led to the adoption of smoke-free homes not only when parents are non-smokers, but also when they smoke. © 2015 Society for the Study of Addiction.

Trends in tobacco smoke exposure and blood lead levels among youths and adults in the United States: the National Health and Nutrition Examination Survey, 1999-2008.

Tobacco smoke is a source of exposure to thousands of toxic chemicals including lead, a chemical of longstanding public health concern. We assessed trends in blood lead levels in youths and adults with cotinine-verified tobacco smoke exposure by using 10 years of data from the National Health and Nutrition Examination Survey. Geometric mean levels of blood lead are presented for increasing levels of tobacco smoke exposure. Regression models for lead included age, race/ethnicity, poverty, survey year, sex, age of home, birth country, and, for adults, alcohol consumption. Lead levels were evaluated for smokers and nonsmokers on the basis of age of residence and occupation. Positive trend tests indicate that a linear relationship exists between smoke exposure and blood lead levels in youths and adults and that secondhand smoke exposure contributes to blood lead levels above the level caused by smoking. Youths with secondhand smoke exposure had blood lead levels suggestive of the potential for adverse cognitive outcomes. Despite remediation efforts in housing and the environment and declining smoking rates and secondhand smoke exposure in the United States, tobacco smoke continues to be a substantial source of exposure to lead in vulnerable populations and the population in general.

To characterize health burden and determine the associated level of equality of laryngeal carcinoma (LC) burden at a global level. One hundred eighty-four countries were organized by socioeconomic status using Human Development Index (HDI) categorizations provided by the United Nations Development Program. Disability-adjusted life years (DALYs), obtained from The Global Health Data Exchange, were calculated and compared between each HDI category for the period from 1990 to 2015. Equality of LC burden was then evaluated with concentration indices. Global LC burden, as measured by age-standardized DALYs, has improved significantly over the 25-year period studied. This burden has declined for very high, high, and medium HDI countries, whereas it has remained unchanged for low HDI countries. The majority of LC global burden was found in high socioeconomic countries before 2010 and has shifted toward low socioeconomic countries, as indicated by concentration indices. Over the last 25 years, Central and Eastern Europe continue to have the largest disease burden in the world. This is the first analysis that we are aware of investigating health disparities of LC at a global level. The global burden of the disease has declined, which is a trend corresponding with significantly reduced smoking behaviors in developed countries. Although the global inequality gap decreased between 2010 and 2015, there remain reasons for concern. Smoking continues to trend upward in low socioeconomic countries, which could increase LC burden in low socioeconomic countries in the near future. A new global initiative directed toward low socioeconomic countries may yield dividends in preventing subsequent disparities in the LC burden. 4.

2011-06-01

We examined prescribing patterns for nicotine replacement therapies (NRTs) in a large psychiatric hospital, before and after the implementation of a smoking ban. We extracted 5 years of NRT utilization data from hospital pharmacy records. The ban went into effect on January 1, 2007. Data reflect NRT prescriptions from 2 years before and 3 years after the ban, and N = 30,908 total inpatient hospital admissions. The monthly rate of total NRT prescriptions increased after the ban from M = 254.25 (SD = 126.60) doses per month to M = 4,467.52 (SD = 1,785.87) doses per month (>1,700% increase, p < .0001). After the smoking ban, clinicians prescribed higher doses of transdermal (but not oral) NRT (Tukey, p < .0001). Comparisons of NRT prescribing across hospital units tentatively suggested that patients being treated on the substance use disorders unit were prescribed more doses of NRT, as well as higher doses of NRT compared with patients on other units. Analysis of trends over time showed no apparent downward trend for NRT usage during the 3 years following the smoking ban, suggesting that clinicians continued to treat nicotine dependence after smoking was restricted. Clinicians are more likely to identify and treat symptoms of nicotine withdrawal when smoking is restricted. Hospitals should consider monitoring prescriptions for NRT as part of their ongoing quality assurance practices so that patients receive aggressive treatment of nicotine withdrawal symptoms--an essential component of high-quality patient care.

2017-08-01

Every day in the USA, approximately 4000 adolescents begin smoking and the adolescent brain is particularly susceptible to nicotine addiction. We present current pediatric trends on tobacco use and exposures, various new products used by adolescents, the adverse biological and behavioral effects of tobacco use and exposures, and tobacco control strategies to eliminate tobacco-related illnesses and deaths in the pediatric population. Twelve-20% of women continue to smoke during pregnancy. New research reveals cognitive differences and behavior-control disorders are seen in elementary school children from prenatal and postnatal exposures. Traditional cigarette smoking has decreased in adolescents; novel and appealing tobacco products have captured their attention, particularly electronic cigarettes, and rates double and often triple from middle to high school. Children with asthma and those living in multi-housing units have higher rates of secondhand smoke exposure than non-asthmatics and children living in single-home dwellings. There is no "safe or risk-free" level of tobacco use or exposure. Tobacco use and exposure in childhood and adolescence must be decreased using evidenced-based strategies to improve child health.

Modeling flight attendants' exposure to secondhand smoke in commercial aircraft: historical trends from 1955 to 1989.

Flight attendants were exposed to elevated levels of secondhand smoke (SHS) in commercial aircraft when smoking was allowed on planes. During flight attendants' working years, their occupational SHS exposure was influenced by various factors, including the prevalence of active smokers on planes, fliers' smoking behaviors, airplane flight load factors, and ventilation systems. These factors have likely changed over the past six decades and would affect SHS concentrations in commercial aircraft. However, changes in flight attendants' exposure to SHS have not been examined in the literature. This study estimates the magnitude of the changes and the historic trends of flight attendants' SHS exposure in U.S. domestic commercial aircraft by integrating historical changes of contributing factors. Mass balance models were developed and evaluated to estimate flight attendants' exposure to SHS in passenger cabins, as indicated by two commonly used tracers (airborne nicotine and particulate matter (PM)). Monte Carlo simulations integrating historical trends and distributions of influence factors were used to simulate 10,000 flight attendants' exposure to SHS on commercial flights from 1955 to 1989. These models indicate that annual mean SHS PM concentrations to which flight attendants were exposed in passenger cabins steadily decreased from approximately 265 μg/m(3) in 1955 and 1960 to 93 μg/m(3) by 1989, and airborne nicotine exposure among flight attendants also decreased from 11.1 μg/m(3) in 1955 to 6.5 μg/m(3) in 1989. Using duration of employment as an indicator of flight attendants' cumulative occupational exposure to SHS in epidemiological studies would inaccurately assess their lifetime exposures and thus bias the relationship between the exposure and health effects. This historical trend should be considered in future epidemiological studies.

Introduction Quitting smoking is a critical step toward diabetes control. It is not known whether smoking rates in adults with diabetes are similar to rates among adults who do not have the disease or whether people with diabetes have increased motivation to quit. We examined prevalence trends of current smoking and quit attempts among US adults with and without diagnosed diabetes from 2001 through 2010. Methods We used data from the 2001 through 2010 Behavioral Risk Factor Surveillance System, a state-based telephone survey of noninstitutionalized US adults, and conducted linear trend analysis and log linear regression. Results The adjusted prevalence of cigarette smoking among adults with diagnosed diabetes was 9% less than adults without diagnosed diabetes (adjusted prevalence ratio [APR], 0.91; 99% confidence interval [CI], 0.89−0.93). Declines in smoking prevalence were greater among adults without diabetes than adults with diagnosed diabetes (P < .001). Among smokers, the adjusted prevalence of quit attempts among adults with diagnosed diabetes was 13% higher than among adults without diagnosed diabetes (APR, 1.13; 99% CI, 1.11−1.15). Among adult smokers with diagnosed diabetes, quit attempts were stable over time for those aged 18 to 44 years and those with a high school education or less. Quit attempts were also stable for older smokers, non-Hispanic African Americans, and Hispanic smokers, regardless of diagnosed diabetes status. Conclusion A large proportion of smokers with diagnosed diabetes seemed to have quit smoking, but more research is needed to confirm success and how difficult it was to achieve. PMID:24050530

Indoor smoking bans have often been associated with reductions in smoking prevalence. However, few studies have evaluated their association with within-person changes in smoking behaviors. We linked longitudinal data from 5,105 adults aged 18-30 years at baseline from the Coronary Artery Risk Development in Young Adults (CARDIA) Study (1985-2011) to state, county, and local policies mandating 100% smoke-free bars and restaurants by census tract. We used fixed-effects models to examine the association of smoking bans with within-person change in current smoking risk, smoking intensity (smoking ≥10 cigarettes/day on average vs. <10 cigarettes/day), and quitting attempts, using both linear and nonlinear adjustment for secular trends. In models assuming a linear secular trend, smoking bans were associated with a decline in current smoking risk and smoking intensity and an increased likelihood of a quitting attempt. The association with current smoking was greatest among participants with a bachelor's degree or higher. In models with a nonlinear secular trend, pooled results were attenuated (confidence intervals included the null), but effect modification results were largely unchanged. Findings suggest that smoking ban associations may be difficult to disentangle from other tobacco control interventions and emphasize the importance of evaluating equity throughout policy implementation.

Objective. To examine time trends in prevalence of smoking and smoking cessation during pregnancy by family income, maternal level of education, skin color, and age. Methods. We conducted three population-based surveys in 2007, 2010, and 2013 with newly delivered mothers living in the municipality of Rio Grande, Southern Brazil. Data were collected using questionnaires administered after delivery in all (two) maternity units in the city, at Dr. Miguel Riet Corrêa Júnior Hospital and at Santa Casa de Misericórdia. Time trends were analyzed using chi-square test for linear trend. Results. Data of 7,572 women showed that the prevalence of smoking before pregnancy decreased from 28% (26.2–29.7) in 2007 to 22% (20.8–24.0) in 2013 (P < 0.001). Prevalence of smoking during pregnancy decreased from 22% (20.4–23.7) in 2007 to 18% (16.6–19.5) in 2013 (P < 0.001). This reduction varied across income ranging from 17% (poorest) to 35% (richest) (P < 0.001). The lower the income, the higher the smoking prevalence during pregnancy. Smoking cessation was more prevalent among women of higher level of education and income. Conclusions. Smoking before and during pregnancy is still highly prevalent and the prevalence of cessation is low pointing to a need to strengthen actions targeting low-income, less educated, black pregnant women.

Background Smoking in movies is prevalent. However, use of content analysis to describe trends in smoking in movies has provided mixed results and has not tapped what adolescents actually perceive. Purpose To assess the prospective trends in the prevalence of smoking in movies as perceived by teenagers, and identify predictors associated with these trends. Methods Using data from the Minnesota Adolescent Community Cohort Study collected during 2000–2006 when participants were aged between 12 and 18 years (N=4735), latent variable growth models were employed to describe the longitudinal trends in the perceived prevalence of smoking in movies using a 4-level scale (never to most of the time) measured every 6 months, and examined associations between these trends and demographic, smoking-related attitudinal and socio-environmental predictors. Analysis was conducted in 2009. Results At baseline, about 50% of participants reported seeing smoking in movies “some of the time”, and another 36% reported “most of the time”. The prevalence of smoking in movies as perceived by teenagers declined over time, and the decline was steeper in those who were aged 14–16 years than those who were younger at baseline (p≤0.05). Despite the decline, teenagers still reported seeing smoking in movies some of the time. Teenagers who reported more close friends who smoked also reported a higher prevalence of smoking in movies at baseline (regression coefficients: 0.04–0.18, p<0.01). Conclusions Teenagers' perception of the prevalence of smoking in movies declined over time, which may be attributable to changes made by the movie industry. Despite the decline, teenagers were still exposed to a moderate amount of smoking imagery. Interventions that further reduce teenage exposure to smoking in movies may be needed to have an effect on adolescent smoking. PMID:21767724

Smoke-free signage in public parks: impacts on smoking behaviour.

PubMed

Platter, Heather N; Pokorny, Steven B

2018-07-01

Behavioural interventions, such as smoke-free signage, are used to support air quality in public outdoor spaces that are not protected by a smoke-free policy, such as states with preemptive clause legislation. However, there is little evidence of the effectiveness of these interventions. This paper is an evaluation of whether smoke-free signage posted in public parks altered smoking behaviours of park patrons. A time-series quasi-experimental design was used. Cigarette butts were collected at the same day and time every week in ten amenities within four parks in 2011. Each park completed a baseline period until a stable trend emerged at six weeks, then received smoke-free signage for the six week intervention period. There were 1684 cigarette butts collected during baseline and 1008 collected during the intervention phase. Wilcoxon signed-rank test demonstrated that smoking at seven out of ten amenities decreased and the overall decrease was significant at p=0.028. Individual parks and amenities grouped by type did not experience a statistically significant change. A neighbourhood median income trend was visually discovered, revealing that as income increased, there was a greater decrease in cigarette butts. This study provides evidence on the impact of smoke-free signage not supported by local ordinance in public parks using a reproducible measure. States, especially those with a preemptive clause legislation, may benefit from incorporating smoke-free signage in public areas to protect community members from exposure to tobacco smoke, reduce littering, and denormalise smoking. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2015-01-01

Introduction: Several states implemented comprehensive smoke-free laws in workplaces (14 states), restaurants (17 states), and bars (13 states) between 2002 and 2007. We tested the hypothesis that public support for smoke-free laws increases at a higher rate in states that implemented smoke-free laws between 2002 and 2007 (group A) than in states that implemented smoke-free laws after that time or not at all (group B). The period before the implementation (1992–2001) was also considered. Methods: Data was used from the Current Population Survey (CPS) Tobacco Use Supplements (TUS), which is representative for the U.S. adult population. Respondents were asked whether they thought smoking should not be allowed in indoor work areas, restaurants, and bars and cocktail lounges. Differences in trends were analyzed with binomial mixed effects models. Results: Population support for smoke-free restaurants and bars was higher among group A than among group B before 2002. After 2002, support for smoke-free restaurants and bars increased at a higher rate among group A than among group B. Population support for smoke-free workplaces did not differ between group A and B, and the increase in support for smoke-free workplaces also did not differ between these groups. Conclusions: The positive association between the implementation of smoke-free restaurant and bar laws and the rate of increase in support for these laws partly supported the hypothesis. The implementation of the laws may have caused support to increase, but also states that have higher support may have been more likely to implement smoke-free laws. PMID:25143293

The big ban on bituminous coal sales revisited: Serious epidemics and pronounced trends feign excess mortality previously attributed to heavy black-smoke exposure

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wittmaack, K.

The effect of banning bituminous coal sales on the black-smoke concentration and the mortality rates in Dublin, Ireland, has been analyzed recently. Based on the application of standard epidemiological procedures, the authors concluded that, as a result of the ban, the total nontrauma death rate was reduced strongly (-8.0% unadjusted, -5.7% adjusted). The purpose of this study was to reanalyze the original data with the aim of clarifying the three most important aspects of the study, (a) the effect of epidemics, (b) the trends in mortality rates due to advances in public health care, and (c) the correlation between mortalitymore » rates and black-smoke concentrations. Particular attention has been devoted to a detailed evaluation of the time dependence of mortality rates, stratified by season. Death rates were found to be strongly enhanced during three severe pre-ban winter-spring epidemics. The cardiovascular mortality rates exhibited a continuous decrease over the whole study period, in general accordance with trends in the rest of Ireland. These two effects can fully account for the previously identified apparent correlation between reduced mortality and the very pronounced ban-related lowering of the black-smoke concentration. The third important finding was that in nonepidemic pre-ban seasons even large changes in the concentration of black smoke had no detectable effect on mortality rates. The reanalysis suggests that epidemiological studies exploring the effect of ambient particulate matter on mortality require improved tools allowing proper adjustment for epidemics and trends.« less

Smoke-free legislation has been a great success for tobacco control but its impact on smoking uptake remains under-explored. We investigated if trends in smoking uptake amongst adolescents differed before and after the introduction of smoke-free legislation in the United Kingdom. Prevalence estimates for regular smoking were obtained from representative school-based surveys for the four countries of the United Kingdom. Post-intervention status was represented using a dummy variable and to allow for a change in trend, the number of years since implementation was included. To estimate the association between smoke-free legislation and adolescent smoking, the percentage of regular smokers was modeled using linear regression adjusted for trends over time and country. All models were stratified by age (13 and 15 years) and sex. For 15-year-old girls, the implementation of smoke-free legislation in the United Kingdom was associated with a 4.3% reduction in the prevalence of regular smoking (P = .029). In addition, regular smoking fell by an additional 1.5% per annum post-legislation in this group (P = .005). Among 13-year-old girls, there was a reduction of 2.8% in regular smoking (P = .051), with no evidence of a change in trend post-legislation. Smaller and nonsignificant reductions in regular smoking were observed for 15- and 13-year-old boys (P = .175 and P = .113, respectively). Smoke-free legislation may help reduce smoking uptake amongst teenagers, with stronger evidence for an association seen in females. Further research that analyses longitudinal data across more countries is required. Previous research has established that smoke-free legislation has led to many improvements in population health, including reductions in heart attack, stroke, and asthma. However, the impacts of smoke-free legislation on the rates of smoking amongst children have been less investigated.

Conclusions: Smoke-free legislation may help reduce smoking uptake amongst teenagers, with stronger evidence for an association seen in females. Further research that analyses longitudinal data across more countries is required. Implications: Previous research has established that smoke-free legislation has led to many improvements in population health, including reductions in heart attack, stroke, and asthma. However, the impacts of smoke-free legislation on the rates of smoking amongst children have been less investigated. Analysis of repeated cross

Objective There has been reduced active smoking, decreased societal acceptance for smoking indoors, and changing smoking policy since the mid-1980s. We quantified passive smoke exposure trends and their relationship with workplace policy. Method We studied 2,504 CARDIA participants (blacks and whites, 18–30 years old when recruited in 1985–86 from four US cities, reexamination 2, 5, 7, 10, and 15 years later) who never reported smoking and attended exams at 10 or 15 years. Results In non-smokers with a college degree (n = 1,581), total passive smoke exposure declined from 16.3 hr/wk in 1985/86 to 2.3 hr/wk in 2000/01. Less education tended to be associated with more exposure at all timepoints for example, in high school or less (n = 349) 22.2 hours/wk in 1985/86 to 8.5 hr/wk in 2000/01. Those who experienced an increase in the restrictiveness of self-reported workplace smoking policy from 1995/96 to 2000/01 were exposed to almost 3 hours per week less passive smoke than those whose workplace policies became less restrictive in this time period. Conclusions The increasing presence of restrictive workplace policies seemed to be a component of the substantial decline in self-reported passive smoke exposure since 1985. PMID:17433426

Background Reports of a relationship between watching smoking in movies and smoking among adolescents have prompted greater scrutiny of smoking in movies by the public health community. Objective To assess the smoking prevalence among adult and adolescent movie characters, examine trends in smoking in movies over time, and compare the data with actual smoking prevalence among US adults and adolescents. Design and methods Smoking status of all major human adolescent and adult movie characters in the top 100 box office hits from 1996 to 2004 (900 movies) was assessed, and smoking prevalence was examined by Motion Picture Association of America (MPAA) rating and year of release. Results The movies contained 5944 major characters, of whom 4911 were adults and 466 were adolescents. Among adult movie characters, the overall smoking prevalence was 20.6%; smoking was more common in men than in women (22.6% v 16.1%, respectively, p<0.001), and was related to MPAA rating category (26.9% for movies rated R (restricted, people aged <17 years require accompanying adult), 17.9% for PG‐13 (parents strongly cautioned that some material might be inappropriate for children) and 10.4% for G/PG (general audiences, all ages; parental guidance suggested for children), p<0.001). In 1996, the smoking prevalence for major adult movie characters (25.7%) was similar to that in the actual US population (24.7%). Smoking prevalence among adult movie characters declined to 18.4% in 2004 (p for trend <0.001), slightly below that for the US population for that year (20.9%). Examination of trends by MPAA rating showed that the downward trend in smoking among adult movie characters was statistically significant in movies rated G/PG and R, but not in those rated PG‐13. A downward trend over time was also found for smoking among adolescent movie characters. There was no smoking among adult characters in 43.3% of the movies; however, in 39% of the movies, smoking prevalence among adult characters

Monitoring disparities in secondhand smoke (SHS) exposure is important for tailoring smoke-free policies to the needs of different groups. We examined disparity and trends in SHS exposure among both nonsmokers and smokers at Japanese workplaces between 2002 and 2012. A total of 32,940 employees in nationally representative, population-based, repeated cross-sectional surveys in 2002, 2007 and 2012 in Japan was analyzed. Adjusted rate ratios for workplace SHS exposure from other people ("everyday" and "everyday or sometimes") were calculated according to covariates, using log-binomial regression models with survey weights. In this survey, employees who do not smoke at workplace are defined as workplace-nonsmokers; and those smoke at workplace are used as workplace-smokers. SHS exposure for smokers does not involve their own SHS. While everyday SHS exposure prevalence in workplace-nonsmokers decreased markedly (33.2% to 11.4%), that in workplace-smokers decreased only slightly (63.3% to 55.6%). Workplace-smokers were significantly more likely to report everyday SHS exposure than workplace-nonsmokers, and the degree of association increased over time: compared with the nonsmokers (reference), covariates-adjusted rate ratio (95% confidence interval) for the smokers increased from 1.70 (1.62-1.77) in 2002 to 4.16 (3.79-4.56) in 2012. Similar results were observed for everyday or sometimes SHS exposure. Compared with complete workplace smoking bans, partial and no bans were consistently and significantly associated with high SHS exposure among both nonsmokers and smokers. We also observed disparities in SHS exposure by employee characteristics, such as age group and worksite scale. Although overall SHS exposure decreased among Japanese employees between 2002 and 2012, the SHS exposure disparity between nonsmokers and smokers widened. Because smokers reported more frequent SHS exposure than nonsmokers, subsequent mortality due to SHS exposure may be higher in smokers than

To evaluate the effect of tobacco prices and the implementation of smoke-free legislation on smoking cessation in Spain, by educational level, across the period 1993-2012. National Health Surveys data for the above two decades were used to calculate smoking cessation in people aged 25-64 years. The relationship between tobacco prices and smoking quit-ratio was estimated using multiple linear regression adjusted for time and the presence of smoke-free legislation. The immediate as well as the longer-term impact of the 2006 smoke-free law on quit-ratio was estimated using segmented linear regression analysis. The analyses were performed separately in men and women with high and low education, respectively. No relationship was observed between tobacco prices and smoking quit-ratio, except in women having a low educational level, among whom a rise in price was associated with a decrease in quit-ratio. The smoke-free law altered the smoking quit-ratio in the short term and altered also pre-existing trends. Smoking quit-ratio increased immediately after the ban - though this increase was significant only among women with a low educational level - and then decreased in subsequent years except among men with a high educational level. A clear relationship between tobacco prices and smoking quit-ratio was not observed in a recent period. After the implementation of smoke-free legislation the trend in the quit ratio in most of the socio-economic groups was different from the trend observed before implementation, so existing inequalities in smoking quit-ratio were not widened or narrowed.

The objective of this study was to evaluate the impact of the 2005 British Columbia Ministry of Health Smoking Cessation Mass Media Campaign on short-term smoking behavior. National cross-sectional data are used with a quasi-experimental approach to test the impact of the campaign. Findings indicate that prevalence and average number of cigarettes smoked per day deviated upward from trend for the rest of Canada (P = .08; P = .01) but not for British Columbia. They also indicate that British Columbia smokers in lower risk groups reduced their average daily consumption of cigarettes over and above the 1999-2004 trend (-2.23; P = .10), whereas smokers in the rest of Canada did not, and that British Columbia smokers in high-risk groups did not increase their average daily consumption of cigarettes over and above the 1999-2004 trend, whereas smokers in the rest of Canada did (2.97; P = .01). The overall poorer performance of high-risk groups is attributed to high exposure to cigarette smoking, which reduces a smoker's chances of successful cessation. In particular, high-risk groups are by definition more likely to be exposed to smoking by peers, but are also less likely to work in workplaces with smoking bans, which are shown to have a substantial impact on prevalence. Results suggest that for mass media campaigns to be more effective with high-risk groups, they need to be combined with other incentives, and that more prolonged interventions should be considered.

Cigarette smoking presented the most significant public health challenge in the United States in the 20th Century and remains the single most preventable cause of morbidity and mortality in this country. A number of System Dynamics models exist that inform tobacco control policies. We reviewed them and discuss their contributions. We developed a theory of the societal lifecycle of smoking, using a parsimonious set of feedback loops to capture historical trends and explore future scenarios. Previous work did not explain the long-term historical patterns of smoking behaviors. Much of it used stock-and-flow to represent the decline in prevalence in themore » recent past. With noted exceptions, information feedbacks were not embedded in these models. We present and discuss our feedback-rich conceptual model and illustrate the results of a series of simulations. A formal analysis shows phenomena composed of different phases of behavior with specific dominant feedbacks associated with each phase. We discuss the implications of our society's current phase, and conclude with simulations of what-if scenarios. Because System Dynamics models must contain information feedback to be able to anticipate tipping points and to help identify policies that exploit leverage in a complex system, we expanded this body of work to provide an endogenous representation of the century-long societal lifecycle of smoking.« less

Several studies in Germany and other European countries have already shown smoking prevalence to be related to education. This study was aimed to investigate time trends in smoking habits in the German cohorts Heidelberg and Potsdam of the European Prospective Investigation into Cancer and Nutrition (EPIC) according to sex, birth cohort, and level of education. Within EPIC, 25,546 and 27,548 participants were recruited in Heidelberg and Potsdam, respectively. Data on smoking were collected by means of a computer-guided interview during the baseline examination between 1994 and 1998. For each birth cohort smoking prevalence and mean number of cigarettes smoked per day at different ages were calculated. Odds ratios and 95% confidence interval for associations between smoking prevalence and educational level were computed by using logistic regression. Smoking prevalence was higher among men than among women, with a smaller difference in younger birth cohorts. Between 1950 and 1960, smoking prevalence among women in the Heidelberg cohort rose sharply (from 12.8% to 51.8% in the least educated group). This strong increase was delayed by 10 years in the Potsdam cohort. Men and women in Heidelberg smoked more cigarettes per day than their counterparts in Potsdam, but in both study centers less educated subjects smoked more than subjects with a higher education. Smoking patterns in the Potsdam and Heidelberg cohorts are quite similar with respect to prevalence and years of lifetime smoking. Since an increasing difference between smoking prevalence of less and high educated individuals is observable, programs on smoking cessation should especially concentrate on persons of lower educational level.

The role of environmental factors in the evolution and maintenance of diversity of antigen receptor gene families which participate in the immune response in mammals is inadequately understood. In order to elucidate the impact of these factors, we have undertaken the analysis of these gene families in the tassel-eared squirrel (Sciurus aberti) which has been separated into discrete subspecies by geographic barriers and whose food resources can be quantitated for estimating environmental quality. In this communication we describe the initial analysis of the complexity and polymorphism of sequences related to T-cell receptor (Tcr) alpha and beta chain genes in two subspecies, Sciurus aberti aberti (Abert) and Sciurus aberti kaibabensis (Kaibab) which have identical habitats and are separated by the Grand Canyon in Arizona, USA. Genomic blot analysis of 60 Abert and 62 Kaibab individuals collected over a 3-year period was performed with mouse Tcrb and Tcra cDNA probes. Sequences homologous to Tcrb-C, Tcrb-J1, and Tcrb-J2 genes were observed in all individuals from both subspecies; although Tcrb-J1 fragments were monomorphic. Tcrb-C and Tcrb-J2 fragments were polymorphic with both species- and subspecies-specific sequences. A single, monomorphic Tcra-C fragment was observed in addition to multiple Tcra-V fragments homologous to the mouse Tcra-V1 subfamily. Abert samples exhibited greater numbers of Tcra-V1 fragments as well as greater polymorphism than Kaibab samples. Heterozygosity estimates of Tcrb-C and Tcra-V1 sequences were determined for annually collected samples and compared with the yearly estimates of availability of hypogeous fungi, one of the major diet items of tassel-eared squirrels. In the Kaibab annual collections, Tcra-V1 heterozygosity declined with the decline in food resource, whereas heterozygosity of Tcrb-C sequences was inversely related to food resource. Similarly, a reduction in food resource for Abert squirrels in 1985 coincided with an

Exposure to job-related secondhand smoke represents a significant, but entirely preventable occupational health risk to non-smoking workers. This article examines trends in smoke-free workplace policies in North Carolina. We also examine whether workers comply with such policies. Data from the Census Bureau's Current Population Survey were analyzed from 1992 through 2002. Trends for North Carolina workers are compared with workers nationally and trends are presented by age, race, gender, and type of worker. North Carolina ranks 35th in the proportion of its workforce reporting a smoke-free place of employment. The proportion of workers reporting such a policy doubled between 1992 and 2002. Females were more likely to reporta smoke-free work environment (72.0%, CI +/- 2.6) than males (61.2%, CI +/- 4.6%). Blue-collar (55.6%, CI +/- 5.5) and service workers (61.2%, CI +/- 8.4), especially males, were less likely to report a smoke-free worksite than white-collar workers (73.4%, CI +/- 2.6). Compliance with a smoke-free policy does not appear to be an issue, only 3.2% of workers statewide reported someone had violated their company's nonsmoking policy While some progress has been made in North Carolina to protect workers from secondhand smoke, significant disparities exist. Smoke-free policies can make a significant difference in reducing exposure to airborne toxins and their associated diseases, and these protective public health policies have not been shown to reduce business revenues. Much has been done to assure the health and safety of workers through public health policy However, opportunities to protect North Carolina workers from the health effects of secondhand smoke are limited by a preemptive state law.

Smoke-free ordinance implementation and advances in smoking cessation (SC) treatment have occurred in the past decade; however, little is known about their impact on SC in patients with coronary artery disease. We conducted a retrospective cohort study of 2,306 consecutive patients from Olmsted County, Minnesota, who underwent their first percutaneous coronary intervention (PCI) from 1999 to 2009, and assessed the trends and predictors of SC after PCI. Smoking status was ascertained by structured telephone survey 6 and 12 months after PCI (ending in 2010). The prevalence of smoking in patients who underwent PCI increased nonsignificantly from 20% in 1999 to 2001 to 24% in 2007 to 2009 (p = 0.14), whereas SC at 6 months after PCI decreased nonsignificantly from 50% (1999 to 2001) to 49% (2007 to 2009), p = 0.82. The 12-month quit rate did not change significantly (48% in 1999 to 2001 vs 56% in 2007 to 2009, p = 0.38), even during the time periods after the enactment of smoke-free policies. The strongest predictor of SC at 6 months after PCI was participation in cardiac rehabilitation (odds ratio [OR] 3.17, 95% confidence interval [CI] 2.05 to 4.91, p <0.001), older age (OR 1.42 per decade, 95% CI 1.16 to 1.73, p <0.001), and concurrent myocardial infarction at the time of PCI (OR 1.77, 95% CI 1.18 to 2.65, p = 0.006). One-year mortality was lower in the group of smokers compared with never smokers (3% vs 7%, p <0.001). In conclusion, SC rates have not improved after PCI over the past decade in our cohort, despite the presence of smoke-free ordinances and improved treatment strategies. Improvements in delivery of systematic services aimed at promoting SC (such as cardiac rehabilitation) should be part of future efforts to improve SC rates after PCI. Copyright © 2015 Elsevier Inc.

To estimate the immediate as well as the longer-term impact of the 2005 smoke-free law on smoking prevalence, cessation and intensity both in the overall population and separately by educational level. Interrupted time-series analyses of 11 cross-sectional nationally representative surveys. Italy, 1999-2010. Adults aged 20-64 years. For each year we computed the prevalence of current smoking, the quit ratio and the mean number of cigarettes smoked per day. All measures were standardized by age. Segmented linear regression analyses were performed for each smoking variable separately by sex. Among males, smoking prevalence decreased by 2.6% (P = 0.002) and smoking cessation increased by 3.3% (P = 0.006) shortly after the ban, but both measures tended to return to pre-ban values in the following years. This occurred among both highly and low-educated males. Among low-educated females, the ban was followed by a 1.6% decrease (P = 0.120) in smoking prevalence and a 4.5% increase in quit ratios (P < 0.001). However, these favourable trends reversed over the following years. Among highly educated females, trends in smoking prevalence and cessation were not altered by the ban. Among both males and females, long-term trends in the daily number of cigarettes, which were already declining well before the implementation of the policy, changed to a minor extent. The impact of the Italian smoke-free policy on smoking and inequalities in smoking was short-term. Smoke-free policies may not achieve the secondary effect of reducing smoking prevalence in the long term, and they may have limited effects on inequalities in smoking. © 2012 The Authors.

Background The role of passive smoking on breast cancer risk was unclear. This study aimed to evaluate the association between passive smoking and breast cancer risk among Chinese women. Methods/Principal Findings A hospital-based case-control study, including 877 breast cancer cases and 890 controls, frequency-matched by age and residence, was conducted. A structured questionnaire was used to collect information on passive smoking history through face-to-face interview by trained interviewers. Unconditional logistic regression models were used to estimate the association between passive smoking and breast cancer risk. A positive association between any passive smoking exposure and breast cancer risk was observed. Compared with women who were never exposed to passive smoking, women who were ever exposed had a higher breast cancer risk, with the adjusted odds ratio (OR) and 95% confidence interval (CI) of 1.35 (1.11-1.65). Similar result was found on home passive smoking exposure and breast cancer risk, but not on workplace passive smoking exposure. Women who were ever exposed to tobacco smoke at home had a higher risk of breast cancer compared with never exposed women, with the adjusted OR (95% CI) of 1.30 (1.05-1.61). Home passive smoking exposure showed significant dose-response relationships with breast cancer risk in smoker-years, cigarettes/day and total pack-years (P trend=0.003, 0.006 and 0.009, respectively). An increased total smoker-years of any passive exposure significantly elevated the risk of breast cancer (P trend<0.001). Positive associations and dose-response relationships were found among postmenopausal women and all subtypes of estrogen receptor (ER) and progesterone receptor (PR) status of breast cancer. Conclusions Passive smoking was associated with an increased risk of breast cancer among non-smoking Chinese women. A stronger positive association with breast cancer risk was seen mainly among postmenopausal women. PMID:25915759

Smoking prevalence is declining at a slower rate in rural than urban settings in the United States (U.S.), and known predictors of smoking do not readily account for this trend difference. Given that socioeconomic and psychosocial determinants of health disparities accumulate in rural settings and that life-course disadvantages are often greater in women than men, we examined whether smoking trends are different for rural and urban men and women. We used yearly cross-sectional data (n = 303,311) from the U.S. National Survey on Drug Use and Health (NSDUH) from 2007 through 2014 to compare cigarette smoking trends in men and women across rural and urban areas. Current smoking status was modelled using logistic regression controlling for confounding risk factors. Regression derived graphs predicting unadjusted prevalence estimates and 95% confidence bands revealed that whereas the smoking trends of rural men, urban men, and urban women significantly declined from 2007 to 2014, the trend for rural women was flat. Controlling for demographic, socioeconomic and psychosocial predictors of smoking did not explain rural women's significantly different trend from those of the other three groups. Rural women lag behind rural men, urban men and urban women in decreasing smoking, a health disparity finding that supports the need for tobacco control and regulatory policies and interventions that are more effective in reducing smoking among rural women.

We report the evidence base that supported the decision to implement the first campus-wide hospital smoking ban in the Republic of Ireland with effect from 1 January 2009. Three separate data sources are utilized; surveillance data collected from patients and staff in 8 surveys between 1997 and 2006, a 1-week observational study to assess smoker behaviour in designated smoking shelters and an attitudinal interview with 28 smoker patients and 30 staff on the implications of the 2004 indoors workplace smoking ban, conducted in 2005. The main outcome measures were trends in prevalence of smoking over time according to age, sex and occupational groups and attitudes to the 2004 ban and a projected outright campus ban. Smoking rates among patients remained steady, 24.2% in 1997/98 and 22.7% in 2006. Staff smoking rates declined from 27.4% to 17.8%, with a strong occupational gradient. Observational evidence suggested a majority of those using smoking shelters in 2005 were women and health-care workers rather than patients. Attitudes of patients and staff were positive towards the 2004 ban, but with some ambivalence on the effectiveness of current arrangements. Staff particularly were concerned with patient safety issues associated with smoking outdoors. The 2004 ban was supported by 87.6% of patients and 81.3% of staff in 2006 and a majority of 58.6% of patients and 52.4% of staff agreed with an outright campus ban being implemented. These findings were persuasive in instigating a process in 2007/08 to go totally smoke-free by 2009, the stages for which are discussed.

Does gravidity influence smoking behaviour in pregnancy? A comparison of multigravid and primigravid women.

This study used the data from a retrospective cross-sectional survey to describe the prevalence of smoking in pregnancy in a large UK sample, over more than 20 years of pregnancies. The main objective was to determine whether women in their second or subsequent pregnancy are more or less likely than primigravidae to change their smoking behaviour. The participants were 7506 ever-pregnant women, from 7702 who answered the second stage of a survey of reproductive history in 2001-02, sent to 10 828 women, aged 18-55 years on the UK electoral register. These women gave detailed information on their last pregnancy. The main outcome measure was self-reported cigarette consumption in the first trimester of pregnancy. Nineteen per cent (1417/7506) of women in this sample smoked in the first trimester of the reported pregnancy. The data showed that there had been a decrease over the last 20 years in smoking prevalence, but this trend was not statistically significant after adjustment for confounding (P(trend) = 0.07). There was evidence that multigravidae were more likely to smoke in their pregnancies than were primigravidae (adjusted OR = 1.24, [95% CI 1.01, 1.53]), with a highly significant trend with increasing pregnancy order (P(trend) < 0.0001). Over time, women who reported smoking before pregnancy (n = 1926), showed a decreasing trend in continuing to smoke the same amount after recognising their pregnancies (P(trend) < 0.0001). After adjustment, multigravid smokers were almost 75% more likely than primigravid smokers to continue to smoke with no change in consumption (adjusted OR = 1.74, [95% CI 1.32, 2.28]), with a clear trend found with increasing pregnancy order (P(trend) = 0.001). In this UK population-based study, multigravidae were more likely to smoke in pregnancy than women pregnant for the first time. If already a smoker, they were much less likely to cut down their smoking once they found out they were pregnant, regardless of age. This suggests that a

To investigate the relationship between smoking rate and periodontal disease prevalence in Sweden. National smoking rates were found from Swedish National Statistics on smoking habits. Based on smoking rates for the years 1970-2010, periodontal disease prevalence estimates were calculated for the age bracket 40-70 years and smoking-associated relative risks between 2.0 and 20.0. The impact of smoking on the population was estimated according to the concept of population attributable fraction. The age-standardized smoking rate in Sweden declined from 44% in 1970 to 15% in 2010. In parallel with the smoking decline the calculated prevalence estimate of periodontal disease dropped from 26% to 12% assuming a 10-fold smoking-associated relative risk. Even at more moderate magnitudes of the relative risk, e.g. 2-fold or 5-fold, the prevalence decrease was quite tangible, suggesting that the current prevalence in Sweden is about 20-50% of the level 40 years ago. The population attributable fraction, estimating the portion of the disease that would have been avoided in the absence of smoking, was 80% in 1970 and 58% in 2010 at a ten-fold relative risk. Calculated estimates of periodontal disease prevalence are closely related to real changes in smoking rate. As smoking rate drops periodontal disease prevalence will drop. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We analyzed the 2004-2012 National Health Interview Survey (NHIS) data. Respondents were aged ≥18 years working in the week prior to the interview. Temporal changes in cigarette smoking prevalence were assessed using logistic regression. We used the regression model to extrapolate to the period 2013-2020. Overall, an estimated 19.0% of working adults smoked cigarettes: 22.4% in 2004 to 18.1% in 2012. The largest declines were among workers in the education services (6.5%) industry and in the life, physical, and social science (9.7%) occupations. The smallest declines were among workers in the real estate and rental and leasing (0.9%) industry and the legal (0.4%) occupations. The 2020 projected smoking prevalences in 15 of 21 industry groups and 13 of the 23 occupation groups were greater than the 2020 Healthy People goal. During 2004-2012, smoking prevalence declined in the majority of industry and occupation groups. The decline rate varied by industry and occupation groups. Projections suggest that certain groups may not reach the 2020 Healthy People goal. Consequently, smoking cessation, prevention, and intervention efforts may need to be revised and strengthened, particularly in specific occupational groups.

Smoking in military settings is of major concern. We aimed to assess the association between personal, family, and military factors and smoking behavior change during compulsory military service in Israel. Participants were soldiers recruited between 1987 and 2008 who were interviewed at recruitment and reinterviewed at discharge (1987-2011) (total: 29 189; males:15 136; females:14 053). The primary outcome variables were smoking initiation during service among nonsmokers at recruitment, and cessation during service among smokers at recruitment. We examined potential predictors of change, and trends by calendar year. Smoking prevalence increased by 39.4% during military service (recruitment: 26.2%, discharge: 36.5%). 18.4% of nonsmoking recruits initiated smoking, and 12.4% of smoking recruits quit smoking between recruitment and discharge. There was no observed trend in initiation between 1987 and 2011. The strongest predictor of smoking initiation among nonsmokers at recruitment was smoking history (former vs. never-smoker, odds ratio (OR) [95% confidence interval [CI

Smoking prevention is less advanced in Germany compared with other European and North American countries, and fewer data exist, especially on the consumption habits at the individual level over time. EPIC Germany, which is part of a European multicentre study on diet and cancer, collected data on individual smoking behaviour and allows for consideration of the changing consumption pattern for both centres and different age groups. Within EPIC 25 546 and 27 548 participants, respectively, were recruited in Heidelberg and Potsdam. Data on smoking habits were collected by means of a computer-guided interview during the baseline examination between 1994 and 1998. For each birth cohort smoking prevalence and mean number of cigarettes smoked per day at different ages were calculated. Additionally, the prevalence of non-filter cigarette smoking was computed. Smoking prevalence in the 1990s was still higher among men (Heidelberg 16.3-32.3%; Potsdam 18.2-29.3%) than among women (Heidelberg 12.8-32.0%; Potsdam 10.4-27.8%). However, the percentage of women smokers was still increasing. Filter cigarettes comprised a growing percentage of the cigarettes smoked, but especially among men differences between both German cohorts can still be seen: depending on age, 10.0-12.7% of men in the Heidelberg cohort smoked non-filter cigarettes, but only 1.1-2.3% in the Potsdam cohort. The quantity smoked was higher in the Heidelberg than in the Potsdam cohort with respect to the mean number of cigarettes smoked per day as well as the pack-years of smoking. In conclusion, smoking habits in the Potsdam and the Heidelberg cohorts did not strongly differ by smoking prevalence. However, they did differ according to the quantity and quality of smoking. These differences, as well as the changes over the last 40 years may contribute to a changing pattern of diseases in different groups of the German population.

We aimed to examine smoking-related content in all 24 James Bond movies in the Eon Productions series from 1962 to 2015. There were favourable downward trends for any smoking by James Bond (p=0.015 for trend), and for tobacco-related spy-gadgetry (p=0.009). Around 20% of Bond's 60 sexual partners smoked in each decade, and most recently in 2012. There were regular mentions of smoking risks to health (starting from 1967) and product placement of branded packs was present in two movies. Overall, the persisting smoking content remains problematic from a public health perspective, especially given the popularity of this movie series. Published by the BMJ Publishing Group Limited.

This study aimed to measure changes in socioeconomic inequalities in smoking and smoking cessation due to the 2006 smoking ban in Luxembourg. Data were derived from the PSELL3/EU-SILC (Panel Socio-Economique Liewen Zu Letzebuerg/European Union--Statistic on Income and Living Conditions) survey, which was a representative survey of the general population aged ≥16 years conducted in Luxembourg in 2005, 2007, and 2008. Smoking prevalence and smoking cessation due to the 2006 smoking ban were used as the main smoking outcomes. Two inequality measures were calculated to assess the magnitude and temporal trends of socioeconomic inequalities in smoking: the prevalence ratio and the disparity index. Smoking cessation due to the smoking ban was considered as a positive outcome. Three multiple logistic regression models were used to assess social inequalities in smoking cessation due to the 2006 smoking ban. Education level, income, and employment status served as proxies for socioeconomic status. The prevalence of smoking decreased by 22.5% between 2005 and 2008 (from 23.1% in 2005 to 17.9% in 2008), but socioeconomic inequalities in smoking persisted. Smoking prevalence decreased by 24.2% and 20.2% in men and women, respectively; this difference was not statistically significant. Smoking cessation in daily smokers due to the 2006 smoking ban was associated with education level, employment status, and income, with higher percentages of quitters among those with a lower socioeconomic status. The decrease in smoking prevalence after the 2006 law was also associated with a reduction in socioeconomic inequalities, including differences in education level, income, and employment status. Although the smoking ban contributed to a reduction of such inequalities, they still persist, indicating the need for a more targeted approach of smoke-free policies directed toward lower socioeconomic groups.

Background Russia has high smoking rates and weak tobacco control policies. A simulation model is used to examine the effect of tobacco control policies on past and future smoking prevalence and premature mortality in Russia. Methods The Russia model was developed using the SimSmoke tobacco control model previously developed for the USA and other nations. The model inputs population size, birth, death and smoking rates specific to Russia. It assesses, individually and in combination, the effect of seven types of policies consistent with the WHO Framework Convention on Tobacco Control (FCTC): taxes, smoke-free air, mass media campaign, advertising bans, warning labels, cessation treatment and youth access policies. Outcomes are smoking prevalence and the number of smoking-attributable deaths by age and gender from 2009 to 2055. Results Increasing cigarette taxes to 70% of retail price, stronger smoke-free air laws, a high-intensity media campaign and comprehensive treatment policies are each potent policies to reduce smoking prevalence and smoking-attributable premature deaths in Russia. With the stronger set of policies, the model estimates that, relative to the status quo trend, smoking prevalence can be reduced by as much as 30% by 2020, with a 50% reduction projected by 2055. This translates into 2 684 994 male and 1 011 985 female premature deaths averted from 2015–2055. Conclusions SimSmoke results highlight the relative contribution of policies to reducing the tobacco health burden in Russia. Significant inroads to reducing smoking prevalence and premature mortality can be achieved through strengthening tobacco control policies in line with FCTC recommendations. PMID:23853252

Women and smoking.

Smoking kills over half a million women each year and is the most important preventable cause of female premature death in several developed countries. However, in many countries, cigarette smoking still tends to be regarded as a mainly male problem. This paper explores the reasons why more attention needs to be paid to issues around smoking and women, even in countries which currently have low levels of female cigarette smoking. The article includes an overview of current patterns and trends of smoking among women, and the factors which influence smoking uptake and cessation in women compared to men. The experience of countries with the longest history of widespread female smoking is used to identify some of the key challenges facing developed and developing countries. Tobacco companies have identified women as a key target group, therefore particular attention is given to the ways in which they have attempted to reach women through advertising and other marketing strategies. It is concluded that in order to halt and ultimately reverse the tobacco epidemic among women, tobacco control policies need to encompass both gender-specific and gender-sensitive approaches. Examples are given of the types of action that are needed in relation to research, public policy and legislation, and education.

This study examined trends in smoking and overweight/obesity rates among United States (US) adults ages 40years and older by race and socio-economic status (SES) across three study periods; pre-recession (2003-2005), recession (2007-2009), and post-recession/Affordable Care Act (2010-2012). Data was obtained from the Behavioral Risk Factor Surveillance System (BRFSS), and multivariable regression analysis was used to examine changes in overweight/obesity, smoking, physical activity and smoking cessation rates over the study periods. There were 2,805,957 adults included in the analysis; 65.5% of the study population was overweight/obese, and 33.3% were current smokers. Smoking prevalence increased marginally among those with lower SES (income<$10,000) from pre-recession (52.5%) to post-recession (52.9%), but declined in other socio-demographic groups. The odds of overweight/obesity increased in the post-recession (OR: 1.22, 95% CI: 1.21-1.23) and recession (OR: 1.11, 95% CI: 1.11-1.12) periods compared with pre-recession, but odds of smoking overall decreased in the post-recession (OR: 0.93, 95% CI: 0.92-0.94) and recession (OR: 0.95, 95% CI: 0.94-0.97) periods. Overweight/obesity increased over the study periods, regardless of race, SES or healthcare access, while smoking rates showed significant declines post-recession compared with pre-recession, except in low SES groups. These findings suggest that strategies focused on reducing overweight/obesity and increasing access to smoking cessation services, especially among low-income adults, are needed. Prospective studies are needed to better evaluate the influence of the economic recession and Affordable Care Act on behavioral risk factors. Copyright © 2017 Elsevier Inc. All rights reserved.

Teenage smoking behaviour following a high-school smoking ban in Chile: interrupted time-series analysis.

To evaluate the effect of a smoking ban in high schools on smoking behaviour among Chilean students. We conducted an interrupted time-series analysis, using repeated cross-sectional data from Chile's school population survey (2000-2011) for high-school students aged 12-18 years and a control group of persons aged 19-24 years. Poisson regression models were used to assess trends in smoking behaviour before and after the policy changes. The outcome measures were self-reported smoking prevalence (any smoking in the past month) and high frequency of smoking (smoking 15 days or more per month). From 2005 to 2011, the prevalence of smoking declined among high-school students by 6.8% per year compared with 3.6% decline per year in the control group. The decline in the target group was 2.9% (95% confidence interval, CI: 0.18 to 5.00) greater. We estimated that 5-6 years after enforcing the law, smoking prevalence among high-school students was 13.7% lower as a result of the ban. The impact of the smoking ban was primarily driven by declines in smoking prevalence among students in grades 8 to 10. The smoking ban did not significantly alter the frequency of smoking. The 2005 school smoking ban reduced smoking prevalence among younger high-school students in Chile. Further interventions targeting older individuals and frequent smokers may be needed.

To assess the association between adolescent smoking and volume of exposure to various forms of media after controlling for multiple relevant covariates. A survey of all adolescents at a large suburban high school assessed: (1) current smoking and susceptibility to future smoking; (2) volume of exposure to various media; and (3) covariates related to smoking. Multivariate logistic regression models assessed relationships between each of the independent variables (media exposures) and the two smoking outcomes after controlling for covariates. Of the 1138 respondents, 19% (n=216) reported current smoking. Forty percent (n=342) of the non-smokers (n=922) were susceptible to future smoking. Students reported exposure to an average of 8.6 (standard deviation 5.1)h of media daily, including 2.6h of music. Those with high exposure to films and music were more likely to be smokers (P(trend)=0.036 and P(trend)<0.001, respectively), and those with high exposure to books were less likely to be smokers (P(trend)<0.001). After controlling for all relevant covariates, those with high exposure to music had greater odds of being smokers than those with low exposure [odds ratio (OR) 1.90, 95% confidence intervals (CI) 1.10-3.30], and those with high exposure to books had lower odds of being current smokers (OR 0.55, 95% CI 0.33-0.94). Exposure to films and music are associated with smoking, but only the relationship between music exposure and smoking persists after rigorous covariate control. Exposure to books is associated with lower odds of smoking.

Objectives In the past decade, waterpipe smoking (a.k.a. hookah, shisha, narghile) has become a global phenomenon. In this review, we provide an updated picture of the main epidemiological trends in waterpipe smoking globally. Data sources Peer-reviewed publications indexed in major biomedical databases between 2004 and 2014. Search keywords included a combination of: waterpipe, hookah, shisha along with epidemiology, patterns, prevalence and predictors. We also used different spellings of waterpipe terms commonly used. Study selection The focus was on studies with large representative samples, national data or high-quality reports that illuminated aspects of the epidemiology and trends in waterpipe smoking. Data extraction Multiple researchers extracted the data independently and collectively decided on the most important and pertinent studies to include in the review. Data synthesis Waterpipe smoking has become a global phenomenon among youth. The global waterpipe epidemic is likely driven by (1) the introduction of manufactured flavoured tobacco (Maassel); (2) the intersection between waterpipe's social dimension and thriving café culture; (3) the evolution of mass communication media; (4) the lack of regulatory/policy framework specific to the waterpipe. Waterpipe smoking is becoming the most popular tobacco use method among youth in the Middle East, and is quickly gaining popularity elsewhere. Important patterns of waterpipe smoking include the predominance among younger, male, high socioeconomic, and urban groups. Intermittent and social use are also noted patterns. Conclusions Waterpipe smoking has become a global public health problem. Developing surveillance, intervention and regulatory/policy frameworks specific to the waterpipe has become a public health priority. PMID:25298368

The smoke-free legislation implemented in Spain in 2006 imposed a partial ban on smoking in public and work places, but the result did not meet expectations. Therefore, a more restrictive anti-smoking law was passed five years later in 2011 prohibiting smoking in all public places, on public transport, and the workplace. With the objective of assessing the impact of the latter anti-smoking legislation on children's exposure to second-hand smoke (SHS), we assessed parent's smoking habits and children's urine cotinine (UC) concentrations in 118 boys before (2005-2006) and after (2011-2012) the introduction of this law. Repeated cross-sectional follow-ups of the "Environment and Childhood Research Network" (INMA-Granada), a Spanish population-based birth cohort study, at 4-5 years old (2005-2006) and 10-11 years old (2011-2012), were designed. Data were gathered by ad-hoc questionnaire, and median UC levels recorded as an objective indicator of overall SHS exposure. Multivariable logistic regression was used to examine the association between parent's smoking habits at home and SHS exposure, among other potential predictors. An increase was observed in the prevalence of families with at least one smoker (39.0% vs. 50.8%) and in the prevalence of smoking mothers (20.3% vs. 29.7%) and fathers (33.9% vs. 39.0%). Median UC concentration was 8.0ng/mL (interquartile range [IQR]: 2.0-21.8) before legislation onset and 8.7ng/mL (IQR: 2.0-24.3) afterwards. In the multivariable analysis, the smoking status of parents and smoking habits at home were statistically associated with the risk of SHS exposure and with UC concentrations in children. These findings indicate that the recent prohibition of smoking in enclosed public and workplaces in Spain has not been accompanied by a decline in the exposure to SHS among children, who continue to be adversely affected. There is a need to target smoking at home in order to avoid future adverse health effects in a population that has no

The aim of the research was to present the prevalence of the regular tobacco smoking, the age of Polish adolescents' smoking onset, as well as the trends in these behaviours in 2010-2014, and to identify the fam- ily factors related to early tobacco initiation, and regular smoking. The study was conducted in 2013/2014 as a part of the HBSC--Health Behaviour in School-aged Children: A WHO collaborative cross-national study, in a representative sample of Polish students (n=4545; 2263 boys, and 2282 girls), in three age groups, in mean age 11.6; 13.6; 15.6. The international, standard HBSC questionnaire was used. Results showed that prevalence of adolescents smoking onset, as well as regular smoking increased with age. There was no statistically significant difference comparing to HBSC study conducted in 2009/10. The important predictors of early tobacco initiation were: the male gender, living in broken or reconstructed family, and living in the rural area. Considering regular smoking, the most important risk factors were: older age (13,15 y.o.) and living with single parent or in reconstructed family. In planning the prevention strategies there is a need to take into account the family role in children and adolescents' smoking prevention, as well as how to support single parents.

Exposure of children to passive smoking is significantly associated with respiratory morbidity. Youngest children between 0-2 years are harmed in the most significant way, while, together with the growing age a decrease is observed of prevalence of respiratory diseases and influence of passive smoking. During repeated investigations of children from European Longitudinal Study of Pregnancy and Childhood (ELSPAC) it was assessed, whether and how in the period from the birth to five years of age varied the rate of children exposed to environment filled with smoke and what were the differences in the frequency of diseases among the groups of children with different exposure level. Some selected characteristics of health were chosen from documentation provided in the 6th, 18th month and 5 years of children's age and processed in four children groups that differ in smoking behaviour of their mothers. The differences were statistically assessed in SPSS programme. In all compared age categories were children of smoking mothers more often exposed to stay in environment filled with smoke: children of middle and heavy smokers more, children of light smokers less. In all groups of smoking mothers, children were more often protected from exposure to passive smoking in the age of six months than after they reached 18 months and 5 years of age: differences were mostly statistically significant on the level of 1% of significance. Attending the kindergarten presents significant protecting factor for five years old children: they are more exposed during weekends than on week days (p < 0.001, resp. p < 0.01). Both respiratory symptomatology and morbidity were highly significantly increased in previous life periods of those children, whose mothers smoked. At the age of five, life in smoking household causes more frequent incidence of asthmatic symptomatology: wheezing and apnoe, and higher prevalence of allergies against home and pollen dust with breathlessness and wheezing as well

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.

Abstract Objective To evaluate the effect of a smoking ban in high schools on smoking behaviour among Chilean students. Methods We conducted an interrupted time-series analysis, using repeated cross-sectional data from Chile’s school population survey (2000–2011) for high-school students aged 12–18 years and a control group of persons aged 19–24 years. Poisson regression models were used to assess trends in smoking behaviour before and after the policy changes. The outcome measures were self-reported smoking prevalence (any smoking in the past month) and high frequency of smoking (smoking 15 days or more per month). Findings From 2005 to 2011, the prevalence of smoking declined among high-school students by 6.8% per year compared with 3.6% decline per year in the control group. The decline in the target group was 2.9% (95% confidence interval, CI: 0.18 to 5.00) greater. We estimated that 5–6 years after enforcing the law, smoking prevalence among high-school students was 13.7% lower as a result of the ban. The impact of the smoking ban was primarily driven by declines in smoking prevalence among students in grades 8 to 10. The smoking ban did not significantly alter the frequency of smoking. Conclusion The 2005 school smoking ban reduced smoking prevalence among younger high-school students in Chile. Further interventions targeting older individuals and frequent smokers may be needed.

To examine the relation between exposure to passive parental smoke and myopia in Chinese children in Singapore. 1334 Chinese children from three schools in Singapore were recruited, all of whom were participants in the Singapore Cohort study Of the Risk factors for Myopia (SCORM). Information on whether the father or mother smoked, number of years smoked, and the number of cigarettes smoked per day during the child's lifetime were derived. These data were correlated with contemporaneously obtained data available in SCORM. The children's cycloplegic autorefraction, corneal curvature radius, and biometry measures were compared with reported parental smoking history. There were 434 fathers (33.3%) and 23 mothers (1.7%) who smoked during their child's lifetime. There were no significant trends observed between paternal smoking and refractive error or axial length. After controlling for age, sex, school, mother's education, and mother's myopia, children with mothers who had ever smoked during their lifetime had more "positive" refractions (adjusted mean -0.28 D v -1.38 D) compared with children whose mother did not smoke (p = 0.012). The study found no consistent evidence of association between parental smoking and refractive error. There was a suggestion that children whose mothers smoked cigarettes had more hyperopic refractions, but the absence of a relation with paternal smoking and the small number of mothers who smoked in this sample preclude definite conclusions about a link between passive smoking exposure and myopia.

Increasing cigarette taxes to 70% of retail price, stronger smoke-free air laws, a high-intensity media campaign and comprehensive treatment policies are each potent policies to reduce smoking prevalence and smoking-attributable premature deaths in Russia. With the stronger set of policies, the model estimates that, relative to the status quo trend, smoking prevalence can be reduced by as much as 30% by 2020, with a 50% reduction projected by 2055. This translates into 2 684 994 male and 1 011 985 female premature deaths averted from 2015-2055. SimSmoke results highlight the relative contribution of policies to reducing the tobacco health burden in Russia. Significant inroads to reducing smoking prevalence and premature mortality can be achieved through strengthening tobacco control policies in line with FCTC recommendations.

In the past decade, waterpipe smoking (a.k.a. hookah, shisha, narghile) has become a global phenomenon. In this review, we provide an updated picture of the main epidemiological trends in waterpipe smoking globally. Peer-reviewed publications indexed in major biomedical databases between 2004 and 2014. Search keywords included a combination of: waterpipe, hookah, shisha along with epidemiology, patterns, prevalence and predictors. We also used different spellings of waterpipe terms commonly used. The focus was on studies with large representative samples, national data or high-quality reports that illuminated aspects of the epidemiology and trends in waterpipe smoking. Multiple researchers extracted the data independently and collectively decided on the most important and pertinent studies to include in the review. Waterpipe smoking has become a global phenomenon among youth. The global waterpipe epidemic is likely driven by (1) the introduction of manufactured flavoured tobacco (Maassel); (2) the intersection between waterpipe's social dimension and thriving café culture; (3) the evolution of mass communication media; (4) the lack of regulatory/policy framework specific to the waterpipe. Waterpipe smoking is becoming the most popular tobacco use method among youth in the Middle East, and is quickly gaining popularity elsewhere. Important patterns of waterpipe smoking include the predominance among younger, male, high socioeconomic, and urban groups. Intermittent and social use are also noted patterns. Waterpipe smoking has become a global public health problem. Developing surveillance, intervention and regulatory/policy frameworks specific to the waterpipe has become a public health priority.

1998-12-01

The present study is a detailed evaluation of age at smoking initiation among university male students in Kuwait based on a random sample of 664 students selected from all students during 1993. The Acturial Life Table analysis revealed that almost one tenth of the students initiated cigarette smoking between ages 16 and 17 with the rate of initiation increasing rapidly thereafter and reaching 30% by age 20 and almost 50% by the time they celebrate their 24th birthday. The most important environmental risk factor positively associated for smoking initiation was observed to be the history of smoking among siblings with a relative risk of 1.4. Compared to students of medicine and engineering, the students of other faculties revealed a higher risk in smoking initiation with an RR = 1.77 for sciences and commerce and 1.61 for other faculties (arts, law, education and Islamic studies). The analysis revealed a rising generation trend in cigarette smoking. There is a need for reduction of this trend among young adults in Kuwait and throughout other countries in the region.

Although Internet cafes have been designated as nonsmoking areas in Korea, smoke-free legislation has allowed the installation of indoor smoking rooms. The purposes of this study were to determine secondhand smoke (SHS) leakage from an Internet café smoking room and to identify factors associated with SHS leakage. PM 2.5 (particulate matter with an aerodynamic diameter ≤2.5 μm) mass concentrations were measured simultaneously both inside and outside the door to the smoking room. During each measurement, a field technician observed how long the smoking room door was opened and closed, the direction of door opening, and the number of smokers. A multivariate linear regression model was used to identify the causality of SHS leakage from the smoking room. A time series of PM 2.5 concentrations both inside and outside the door to the smoking room showed a similar trend. SHS leakage was significantly increased because of factors associated with the direction of the smoking room door being opened, the duration of how long the smoking room door was opened until it was closed, and the average PM 2.5 concentration inside the smoking room when the door was opened. SHS leakage from inside the smoking room to outside the smoking room was evident especially when the smoking room door was opened. Since the smoking room is not effective in preventing SHS exposure, the smoking room should be removed from the facilities to protect citizens from SHS exposure through revision of the current legislation, which permits installation of a smoking room. This paper concerns secondhand smoke (SHS) leakage from indoor smoking room. Unlike previous studies, the authors statistically analyzed the causality of PM 2.5 concentration leakage from a smoking room using time-series analysis. Since the authors selected the most common smoking room, the outcomes could be generalized. The study demonstrated that SHS leakage from smoking room and SHS leakage were clearly associated with door opening

Initial insight into why physical activity may help prevent adolescent smoking uptake.

Whereas research supports the importance of regular physical activity to decrease the likelihood of smoking uptake, the mechanisms accounting for this relationship are poorly understood. We sought to determine whether the enjoyment or reward derived from physical activity is one mechanism underlying the relationship between smoking and physical activity. The sample was composed of 1374 adolescents participating in a prospective longitudinal survey study of health behaviors. Variables were measured via self-report every six months for eight waves of data spanning four years. An associative processes latent growth curve model revealed a significant and negative indirect effect of baseline physical activity on baseline smoking through baseline physical activity reward (b(indirect)=-.18, z=-3.11, p=.002; 95% CI=-.29, -.07). Similarly, there was a significant and negative indirect effect of physical activity trend on smoking trend through physical activity reward trend (b(indirect)=-.16, z=-2.09, p=.04; 95% CI=-.30, -.01). The effect of physical activity on smoking at baseline and across time was completely mediated by physical activity reward. There was less support for the idea that smoking progression was associated with reduced physical activity reward and subsequent declines in physical activity. This study provides the first evidence implicating physical activity reward as one mechanism by which physical activity reduces the likelihood of adolescent smoking uptake. Smoking prevention interventions that promote physical activity and target physical activity enjoyment may have an important impact on adolescent smoking initiation and progression.

The purpose of this study is to estimate and compare smoking prevalence over two time periods in a Manitoba First Nation community. Data fromtwo independent Diabetes Screening Studies in Sandy Bay First Nation, collected in 2002/2003 (n = 482) and 2011/2012 (n = 596),were used. Crude prevalence of current and ever smoking as well as current smoke exposure was estimated. Change over time was tested using a χ² statistic. The crude prevalence of current smoking was 74.0% (95% confidence interval [CI]: 70.1, 78.0) in 2002/2003 and 80.0% (95% CI: 76.8, 83.2) in 2011/2012. The crude prevalence of ever smoking was 83.0% in 2002/2003 and 91.4% in 2011/2012. The prevalence of both current smoking status and ever smoking were significantly higher in 2011/2012 compared to 2002/2003 (p = 0.020 and p < 0.001 respectively). Among participants who were not current smokers, 58.5% (95% CI: 49.6, 67.4) and 76.5% (95% CI: 68.9, 84.1) reported at least one person who smoked in the home in 2002/2003 and 2011/2012 respectively (p = 0.003). In 2011/2012, 96.5% (95% CI: 94.8, 98.2) of those who reported having any children under the age of 18 living in the home were either a current smoker and/or reported that someone else smoked in the home. Public health and policy initiatives are needed to address the increase in smoking prevalence in the study community.

GATA3 Abundance Is a Critical Determinant of T Cell Receptor β Allelic Exclusion

ABSTRACT Allelic exclusion describes the essential immunological process by which feedback repression of sequential DNA rearrangements ensures that only one autosome expresses a functional T or B cell receptor. In wild-type mammals, approximately 60% of cells have recombined the DNA of one T cell receptor β (TCRβ) V-to-DJ-joined allele in a functional configuration, while the second allele has recombined only the DJ sequences; the other 40% of cells have recombined the V to the DJ segments on both alleles, with only one of the two alleles predicting a functional TCRβ protein. Here we report that the transgenic overexpression of GATA3 leads predominantly to biallelic TCRβ gene (Tcrb) recombination. We also found that wild-type immature thymocytes can be separated into distinct populations based on intracellular GATA3 expression and that GATA3LO cells had almost exclusively recombined only one Tcrb locus (that predicted a functional receptor sequence), while GATA3HI cells had uniformly recombined both Tcrb alleles (one predicting a functional and the other predicting a nonfunctional rearrangement). These data show that GATA3 abundance regulates the recombination propensity at the Tcrb locus and provide new mechanistic insight into the historic immunological conundrum for how Tcrb allelic exclusion is mediated.

Counting the costs of children's smoking.

Foulds, J.; Godfrey, C.

The recent publication of the 1994 OPCS survey of smoking among secondary school children confirmed that the Health of the Nation target for children's smoking (a reduction in regular smoking from 8% in 1988 to less than 6% in 1994) has not been achieved. In 1994, 12% of English schoolchildren aged 11-15 were regular smokers (as were 12% in Scotland, 9% in Wales, and 12.5% in Northern Ireland). In 1994 the government spent around 10 million pounds on initiatives to prevent smoking, but received around 8643 million pounds in tax receipts from tobacco sales, about 108 million pounds of which was tax receipts from the illegal sale of cigarettes to children under 16 years old. The tobacco industry spent an estimated 100 million pounds on promotional activities. Improving current trends in children's smoking by the year 2000 will require decisive action by the government. The government should legislate to ban tobacco advertising and should use the 108 million pounds taken each year in taxes from smoking children to fund smoking cessation and prevention initiatives.

Understanding patterns and trends of smoking among youths is of major importance for the assessment of the burden of smoking in the society and efforts to decrease it. The aims were to determine the prevalence and trends of smoking among adolescents in Muenster, Germany, and to assess its relation to youths' awareness of tobacco advertisement. Information on smoking habits was collected during two school-based surveys (1994/1995 and 1999/2000) of 12- to 15-year-old adolescents (3934 students in 1994/5 and 4028 students in 1999/2000) in Muenster, Germany. In addition, in 1994/1995 information about youths' awareness and appreciation of tobacco advertisement was collected. During the 5-year period, the prevalence of current smoking increased from 21.3 to 28.3%, and daily smoking increased from 10.0 to 14.2%. Among girls, daily smoking increased by 62% during this period. Almost all participants (94%) in 1994/1995 knew a tobacco brand, and appreciation of tobacco advertisement was strongly associated with the frequency of smoking. Smoking is increasing among adolescents in Germany especially among girls. These data are a cause of concern and call for efforts to reverse these trends, which should include a ban on tobacco advertisement in Germany.

TSNA levels in machine-generated mainstream cigarette smoke: 35 years of data.

This paper characterizes historical and current tobacco specific nitrosamine (TSNA) levels in mainstream (MS) cigarette smoke of US commercial cigarettes. To conduct this analysis, we gathered 35 years of published data of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and N-nitrosonornicotine (NNN) levels in MS cigarette smoke. We also assessed internal data of MS smoke NNK and NNN levels generated from various market monitoring initiatives and from control cigarettes used in a multi-year program for testing cigarette ingredients. In all, we analyzed machine smoking data from 401 cigarette samples representing a wide range of products and design characteristics from multiple manufacturers and market leaders. There was no indication that TSNA levels systematically increased in cigarette MS smoke over the 35-year analysis period. In particular, TSNA levels expressed as either per cigarette or normalized for tar suggest a downward trend in MS smoke over the past 10 years. The apparent downward trend in TSNA levels in MS smoke may reflect industry and agricultural community efforts to reduce levels of TSNAs in tobacco and cigarette smoke. Copyright © 2013 Elsevier Inc.

Mackay, Daniel F.; Haw, Sally; Pell, Jill P.

2011-01-01

Objectives In Scotland, legislation was implemented in March 2006 prohibiting smoking in all wholly or partially enclosed public spaces. We investigated the impact on attempts to quit smoking and smoking prevalence. Methods We performed time series models using Box-Jenkins autoregressive integrated moving averages (ARIMA) on monthly data on the gross ingredient cost of all nicotine replacement therapy (NRT) prescribed in Scotland in 2003–2009, and quarterly data on self-reported smoking prevalence between January 1999 and September 2010 from the Scottish Household Survey. Results NRT prescription costs were significantly higher than expected over the three months prior to implementation of the legislation. Prescription costs peaked at £1.3 million in March 2006; £292,005.9 (95% CI £260,402.3, £323,609, p<0.001) higher than the monthly norm. Following implementation of the legislation, costs fell exponentially by around 26% per month (95% CI 17%, 35%, p<0.001). Twelve months following implementation, the costs were not significantly different to monthly norms. Smoking prevalence fell by 8.0% overall, from 31.3% in January 1999 to 23.7% in July–September 2010. In the quarter prior to implementation of the legislation, smoking prevalence fell by 1.7% (95% CI 2.4%, 1.0%, p<0.001) more than expected from the underlying trend. Conclusions Quit attempts increased in the three months leading up to Scotland's smoke-free legislation, resulting in a fall in smoking prevalence. However, neither has been sustained suggesting the need for additional tobacco control measures and ongoing support. PMID:22110585

Socioeconomic inequalities in smoking habits have stabilized in many Western countries. This study aimed at evaluating whether socioeconomic disparities in smoking habits are still enlarging in Italy and at comparing the impact of education and occupation. In the frame of the GEIRD study (Gene Environment Interactions in Respiratory Diseases) 10,494 subjects, randomly selected from the general population aged 20-44 years in seven Italian centres, answered a screening questionnaire between 2007 and 2010 (response percentage = 57.2%). In four centres a repeated cross-sectional survey was performed: smoking prevalence recorded in GEIRD was compared with prevalence recorded between 1998 and 2000 in the Italian Study of Asthma in Young Adults (ISAYA). Current smoking was twice as prevalent in people with a primary/secondary school certificate (40-43%) compared with people with an academic degree (20%), and among unemployed and workmen (39%) compared with managers and clerks (20-22%). In multivariable analysis smoking habits were more affected by education level than by occupation. From the first to the second survey the prevalence of ever smokers markedly decreased among housewives, managers, businessmen and free-lancers, while ever smoking became even more common among unemployed (time-occupation interaction: p = 0.047). At variance, the increasing trend in smoking cessation was not modified by occupation. Smoking prevalence has declined in Italy during the last decade among the higher socioeconomic classes, but not among the lower. This enlarging socioeconomic inequality mainly reflects a different trend in smoking initiation.

Changes in Smoking Rates Among Pregnant Women and the General Female Population in Australia, Finland, Norway, and Sweden

Abstract Introduction: Smoking rates have dropped substantially in most developed countries in recent decades. This general trend has, however, not always been evident among women—particularly younger women. Smoking habits do, however, often change in connection with pregnancy and the aim of this study is to determine whether smoking during pregnancy follows general trends in smoking rates in the general female population in four countries with active anti-tobacco policies and decreasing population smoking rates. Methods: Changes in rates of persistent smoking, that is, smoking in late pregnancy or daily smoking among all women of childbearing age were described according to age groups. Data were retrieved from the Australian Household Drug Surveys during 2000–2013 and from registries and surveys in Finland, Norway, and Sweden between 1995 and 2014. Results: In general, persistent smoking has decreased and late-pregnancy smoking rates are lower than daily smoking rates among all women. However, younger women are more likely to be persistent smokers regardless of pregnancy status. In Norway and Finland, persistent smoking was most common among young pregnant women and in Sweden there was an increased polarization between age groups. In Australia, a steady decrease in smoking rates appears to have stalled in younger pregnant women. Conclusion: Although smoking has declined substantially in recent decades, there are groups lagging behind this general trend. Young pregnant women are of particular concern in this respect. The possibility that these findings reflect the changing characteristics of younger pregnant women is discussed. Implications: This study puts recent trends in maternal smoking into a broader context by relating developments to changes in smoking rates among women in general. By using similar data from four countries we were able to follow changes in smoking rates “within” groups of women within the four countries without being limited by

Smoking is the main preventable lifestyle-related risk factor threatening human health. In this study, time trends in smoking behaviour between 1996 and 2005 among adolescents enrolled in secondary school were assessed. In 1996, 2001 and 2005, a survey was conducted in the south-eastern region of the Netherlands. All students in second and fourth year of secondary education (1996: n = 20 000; 2001: n = 27 500; 2005: n = 24 000) were asked to complete a questionnaire about their smoking behaviour. A simulation model was used to estimate lifetime health gains related to the observed trends. In 1996, 2001 and 2005, the number of questionnaires analysed were 13 554 (68%), 20 767 (76%) and 17 896 (75%), respectively. The results show a decrease in 'ever smoking' as well as 'current smoking' between 1996 and 2005. Among second year high school students, current smoking prevalence decreased from 22.2% in 1996 to 8.0% in 2005 (P(trend) < 0.001). Among fourth year students, current smoking declined from 37.5% in 1996 to 22.0% in 2005 (P(trend) < 0.001). Time trends were not influenced by gender or educational level. Model projections show that if these students not take up smoking later in life, 11 500 new cases of COPD, 3400 new cases of lung cancer and 1800 new cases of myocardial infarction could be prevented for the Dutch 13-year-olds. This study found that, in the past decade, smoking prevalence among adolescents has declined by almost 50%, potentially resulting in a considerable reduction in new cases of COPD or lung cancer.

The role of tobacco control policies in reducing smoking and deaths caused by smoking in an Eastern European nation: results from the Albania SimSmoke simulation model.

The Albania SimSmoke simulation model is used to examine the effects of tobacco control policies. The model is used to consider the projected trends in smoking prevalence and associated smoking-attributable deaths in the absence of new policies, and then to examine the effect of new policies that are consistent with the Framework Convention for Tobacco Control (FCTC) on these outcomes. The model shows that significant inroads to reducing smoking prevalence and premature mortality can be achieved through tax increases. Acomprehensive strategy to further reduce smoking rates should include a media campaign complete with programs to publicize and enforce clean air laws, a comprehensive cessation treatment program, strong health warnings, advertising bans, and youth access laws. Besides presenting the benefits of a comprehensive tobacco control strategy, the model helps to identify important information needed for both modeling and policymaking. The effectiveness of future tobacco control policy will require proper surveillance and evaluation schemes for Albania.

provided in this update, an increase of eight countries from the original review. The nature of the intervention precludes randomized controlled trials. Thirty-six studies used an interrupted time series study design, 23 studies use a controlled before-and-after design and 18 studies are before-and-after studies with no control group; six of these studies use a cohort design. Seventy-two studies reported health outcomes, including cardiovascular (44), respiratory (21), and perinatal outcomes (7). Eleven studies reported national mortality rates for smoking-related diseases. A number of the studies report multiple health outcomes. There is consistent evidence of a positive impact of national smoking bans on improving cardiovascular health outcomes, and reducing mortality for associated smoking-related illnesses. Effects on respiratory and perinatal health were less consistent. We found 24 studies evaluating the impact of national smoke-free legislation on smoking behaviour. Evidence of an impact of legislative bans on smoking prevalence and tobacco consumption is inconsistent, with some studies not detecting additional long-term change in existing trends in prevalence. Since the first version of this review was published, the current evidence provides more robust support for the previous conclusions that the introduction of a legislative smoking ban does lead to improved health outcomes through reduction in SHS for countries and their populations. The clearest evidence is observed in reduced admissions for acute coronary syndrome. There is evidence of reduced mortality from smoking-related illnesses at a national level. There is inconsistent evidence of an impact on respiratory and perinatal health outcomes, and on smoking prevalence and tobacco consumption.

Smoking Patterns and Their Relationship to Drinking Among First-Year College Students

PubMed Central

2014-01-01

Introduction: Unlike older smokers, young adult smokers frequently engage in light and intermittent smoking. It remains unclear how stable such smoking patterns are over time, as substantial variability exists between these smokers. This study identified subgroups of college student smokers based on the trajectory of their smoking frequency during the first year of college, thereby examining stability versus instability over time. We then tested if the interplay between drinking and smoking differed in the identified groups to determine the relative role drinking may play in intermittent versus more regular smoking. Methods: Incoming college students at 3 institutions completed online biweekly surveys of their daily substance use throughout the first year of college. Students who reported smoking at least 1 cigarette during this year (n = 266) were included in analyses (70% female, 74% White). Results: Group-based trajectory modeling identified 5 groups of smokers, 3 of which maintained their smoking frequency throughout the year (77%), and 2 groups of infrequent smokers showed significant trends (11% increasing, 12% decreasing). Notably, nondaily smoking was maintained at different specific frequencies (e.g., 1 vs. 3 days per week). Identified groups differed in the relationship between drinking and smoking, where cooccurrence was particularly strong among infrequent smokers, and trends in smoking quantity differed between groups. Conclusions: While there was a diversity of smoking patterns in the sample, patterns of intermittent smoking remain relatively stable for a majority of students throughout the year. Intervention messages targeting drinking and smoking should be tailored on the basis of smoking frequency. PMID:24415586

Recent trends in aviation turbine fuel properties

Plots and tables, compiled from Department of Energy (and predecessor agency) inspection reports from 1969 to 1980, present ranges, averages, extremes, and trends for most of the 22 properties of Jet A aviation turbine fuel. In recent years, average values of aromatics content, mercaptan sulfur content, distillation temperature of 10 percent recovered, smoke point, and freezing point show small but recognizable trends toward their specification limits. About 80 percent of the fuel samples had at least one property near specification, defined as within a standard band about the specification limit. By far the most common near-specification properties were aromatics content, smoke point, and freezing point.

The Contribution of Smoking to Black-White Differences in U.S. Mortality

Smoking has significantly impacted American mortality and remains a major cause of morbidity and mortality. No previous study has systematically examined the contribution of smoking-attributable deaths to mortality trends among blacks or to black-white mortality differences at older ages over time in the United States. In this article, we employ multiple methods and data sources to provide a comprehensive assessment of this contribution. We find that smoking has contributed to the black-white gap in life expectancy at age 50 for males, accounting for 20 % to 48 % of the gap between 1980 and 2005, but not for females. The fraction of deaths attributable to smoking at ages above 50 is greater for black males than for white males; and among men, current smoking status explains about 20 % of the black excess relative risk in all-cause mortality at ages above 50 without adjustment for socioeconomic characteristics. These findings advance our understanding of the contribution of smoking to contemporary mortality trends and differences and reinforce the need for interventions that better address the needs of all groups.

Few studies examine nativity disparities in smoking in the U.S., thus a major gap remains in understanding whether immigrant Latinos’ smoking prevalence is stable, converging, or diverging, compared with U.S.-born Latinos. This study aimed to disentangle the roles of period changes, duration of U.S. residence, and immigrant arrival cohort in explaining the gap in smoking prevalence between foreign-born and U.S.-born Latinos. Using repeated cross-sectional data spanning 1998–2013 (U.S. National Health Interview Survey), regressions predicted current smoking among foreign-born and U.S.-born Latino men and women (n = 12,492). We contrasted findings from conventional regression analyses that simply include period and duration of residence effects, to two methods of assessing arrival cohort effects: the first accounted for baseline differences in smoking among arrival cohorts, while the second examined smoking probabilities by tracking foreign-born arrival cohorts as they increase their duration of U.S. residence. Findings showed that Latino immigrants maintained lower prevalence of current smoking compared with U.S.-born Latinos over the period 1998–2013, and that longer duration of U.S. residence is associated with lower odds of smoking among men. Two findings are particularly novel: (1) accounting for immigrant arrival cohort dampens the overall protective effect of duration of residence among men; and (2) the earliest arrival cohort of Latino immigrant men experienced the steepest decline in smoking over duration of U.S. residence. Results have methodological and theoretical implications for smoking studies and the Latino mortality paradox. PMID:28257125

The association of waterpipe tobacco (WPT) smoking with gastric cancer (GC) risk was suggested. A hospital-based case-control study was conducted to examine the association of WPT with GC risk among Vietnamese men, in Hanoi city, during the period of 2003-2011. Newly-diagnosed GC cases (n = 454) and control patients (n = 628) were matched by age (+/- 5 years) and the year of hospitalization. Information on smoking and alcohol drinking habits and diet including salty food intake and fruits/vegetables consumption were obtained by the interview. Maximum likelihood estimates of odds ratios (ORs) and corresponding 95% confidence intervals (Cis) were obtained using conditional logistic regression models. The group with the highest consumption of citrus fruits showed a significantly low GC risk (OR = 0.6, 95%CI = 0.4-0.8, P for trend = 0.002). However, there was no association of raw vegetable consumption with GC risk. Referring to never smokers, GC risk was significantly higher in current WPT smokers (OR = 1.8, 95%CI = 1.3-2.4), and it was more evident in exclusively WPT smokers (OR = 2.7, 95%CI = 1.2-6.5). GC risk tended to be higher with daily frequency and longer duration of WPT smoking but these trends were not statistically significant (P for trend: 0.144 and 0.154, respectively). GC risk of those who started smoking WPT before the age of 25 was also significantly high (OR = 3.7, 95%CI = 1.2-11.3). Neither cigarette smoking nor alcohol drinking was related to GC risk. The present findings revealed that WPT smoking was positively associated with GC risk in Vietnamese men.

Background: Support for smoke-free policies increases over time and particularly after implementation of the policy. In this study we examined whether the comprehensiveness of such policies moderates the effect on support among smokers. Methods: We analysed two waves (pre- and post-smoke-free legislation) of the International Tobacco Control (ITC) surveys in France, Germany, and the Netherlands, and two pre-legislation waves of the ITC surveys in UK as control. Of 6,903 baseline smokers, 4,945 (71.6%) could be followed up and were included in the analyses. Generalised Estimating Equations (GEE) were used to compare changes in support from pre- to post-legislation to the secular trend in the control country. Multiple logistic regression models were employed to identify predictors of individual change in support. Findings: In France, the comprehensive smoking ban was associated with sharp increases in support for a total smoking ban in drinking establishments and restaurants that were above secular trends. In Germany and the Netherlands, where smoke-free policies and compliance are especially deficient in drinking establishments, only support for a total smoking ban in restaurants increased above the secular trend. Notable prospective predictors of becoming supportive of smoking bans in these countries were higher awareness of cigarette smoke being dangerous to others and weekly visiting of restaurants. Conclusions: Our findings suggest that smoke-free policies have the potential to improve support once the policy is in place. This effect seems to be most pronounced with comprehensive smoking bans, which thus might be the most valid option for policy-makers despite their potential for creating controversy and resistance in the beginning.

Objectives. We assessed attitudes and beliefs about smoke-free laws, compliance, and secondhand smoke exposure before and after implementation of a comprehensive smoke-free law in Mexico City. Methods. Trends and odds of change in attitudes and beliefs were analyzed across 3 representative surveys of Mexico City inhabitants: before implementation of the policy (n = 800), 4 months after implementation (n = 961), and 8 months after implementation (n = 761). Results. Results indicated high and increasing support for 100% smoke-free policies, although support did not increase for smoke-free bars. Agreement that such policies improved health and reinforced rights was high before policy implementation and increased thereafter. Social unacceptability of smoking increased substantially, although 25% of nonsmokers and 50% of smokers agreed with smokers' rights to smoke in public places at the final survey wave. Secondhand smoke exposure declined generally as well as in venues covered by the law, although compliance was incomplete, especially in bars. Conclusions. Comprehensive smoke-free legislation in Mexico City has been relatively successful, with changes in perceptions and behavior consistent with those revealed by studies conducted in high-income countries. Normative changes may prime populations for additional tobacco control interventions. PMID:20466952

Comparison of True and Smoothed Puff Profile Replication on Smoking Behavior and Mainstream Smoke Emissions

PubMed Central

2015-01-01

To estimate exposures to smokers from cigarettes, smoking topography is typically measured and programmed into a smoking machine to mimic human smoking, and the resulting smoke emissions are tested for relative levels of harmful constituents. However, using only the summary puff data—with a fixed puff frequency, volume, and duration—may underestimate or overestimate actual exposure to smoke toxins. In this laboratory study, we used a topography-driven smoking machine that faithfully reproduces a human smoking session and individual human topography data (n = 24) collected during previous clinical research to investigate if replicating the true puff profile (TP) versus the mathematically derived smoothed puff profile (SM) resulted in differences in particle size distributions and selected toxic/carcinogenic organic compounds from mainstream smoke emissions. Particle size distributions were measured using an electrical low pressure impactor, the masses of the size-fractionated fine and ultrafine particles were determined gravimetrically, and the collected particulate was analyzed for selected particle-bound, semivolatile compounds. Volatile compounds were measured in real time using a proton transfer reaction-mass spectrometer. By and large, TP levels for the fine and ultrafine particulate masses as well as particle-bound organic compounds were slightly lower than the SM concentrations. The volatile compounds, by contrast, showed no clear trend. Differences in emissions due to the use of the TP and SM profiles are generally not large enough to warrant abandoning the procedures used to generate the simpler smoothed profile in favor of the true profile.

Many countries have introduced legislations for public smoking bans to reduce the harmful effects of exposure to tobacco smoke. Smoking bans cause significant reductions in admissions for acute coronary syndromes but their impact on respiratory diseases is unclear. In Geneva, Switzerland, two popular votes led to a stepwise implementation of a state smoking ban in public places, with a temporary suspension. This study evaluated the effect of this smoking ban on hospitalisations for acute respiratory and cardiovascular diseases. This before and after intervention study was conducted at the University Hospitals of Geneva, Switzerland, across 4 periods with different smoking legislations. It included 5,345 patients with a first hospitalisation for acute coronary syndrome, ischemic stroke, acute exacerbation of chronic obstructive pulmonary disease, pneumonia and acute asthma. The main outcomes were the incidence rate ratios (IRR) of admissions for each diagnosis after the final ban compared to the pre-ban period and adjusted for age, gender, season, influenza epidemic and secular trend. Hospitalisations for acute exacerbation of chronic obstructive pulmonary disease significantly decreased over the 4 periods and were lowest after the final ban (IRR=0.54 [95%CI: 0.42-0.68]). We observed a trend in reduced admissions for acute coronary syndromes (IRR=0.90 [95%CI: 0.80-1.00]). Admissions for ischemic stroke, asthma and pneumonia did not significantly change. A legislative smoking ban was followed by a strong decrease in hospitalisations for acute exacerbation of chronic obstructive pulmonary disease and a trend for reduced admissions for acute coronary syndrome. Smoking bans are likely to be very beneficial for patients with chronic obstructive pulmonary disease.

Tobacco smoke, active or passive exposure was the major cause of preventable morbidity and mortality in the world during twentieth century and will continue to be the same in the twenty-first century also if the current trends continue. Both active and passive smoking are having significance in relation to child health. Exposure starts antenatally from placenta to the fetus and later phases through passive exposure to experimental and regular smoking and ultimately addiction and habitual smoking. Evidences are in favour of causal relationship with intrauterine growth restriction, sudden infant death syndrome, decreased pulmonary function, increased risk for respiratory tract infection, otitis media, wheeze, asthma, neurobehavioral disorders, cleft palate and triggering pathogenesis of fetal and childhood onset of adult diseases, especially pulmonary and cardio vascular diseases. All these facts stress the importance of behavioral changes in the population as well as stringent public health measures and legislation for ensuring smoke free work places, public places and households for children. M POWER- Package by WHO is a novel global initiative taking us closer to the target of achieving tobacco free environment for children in the near future.

Second-hand tobacco smoke (SHS) exposure at home, especially among children, is a serious issue in Viet Nam. During the past decade, much effort has been taken for tobacco control in the country, including various prgorammes aiming to reduce SHS exposure among adults and children. This article analysed trends and factors associated with SHS exposure at home among school children aged 13-15 in Viet Nam, using the Global Youth Tobacco Surveys conducted in 2007 and 2014. Descriptive and inferential statistical methods with logistic regression were applied. Overall, there was a significant reduction in the level of exposure, from 58.5% (95%CI: 57.6-59.3) in 2007 to 47.1% (95%CI: 45.4-48.8) in 2014. Of the associated factors, having one or both parents smoking was significantly associated with the highest odds of SHS exposure at home (OR=5.0; 95%CI: 4.2-6.1). Conversely, having a mother with a college or higher education level was found to be a protective factor (OR=0.5; 95%CI: 0.3-0.8).

Economic effect of restaurant smoking restrictions on restaurant business in Massachusetts, 1992 to 1998.

To determine if restaurant business declines or improves after the implementation of restrictive restaurant smoking policies. Analysis used a pre/post-quasi-experimental design that compared town meals tax receipts before and after the imposition of highly restrictive restaurant smoking policies in adopting versus non-adopting communities. The effect of restaurant smoking policies was estimated using a fixed effects regression model, entering a panel of 84 months of data for the 239 towns in the study. A separate model estimated the effect of restaurant smoking policies on establishments that served alcohol. Change in the trend in meals tax revenue (adjusted for population) following the implementation of highly restrictive restaurant smoking policies. The local adoption of restrictive restaurant smoking policies did not lead to a measurable deviation from the strong positive trend in revenue between 1992 and 1998 that restaurants in Massachusetts experienced. Controlling for other less restrictive restaurant smoking policies did not change this finding. Similar results were found for only those establishments that served alcoholic beverages. Highly restrictive restaurant smoking policies do not have a significant effect on a community's level of meal receipts, indicating that claims of community wide restaurant business decline under such policies are unwarranted.

Young people in the United States are exposed to secondhand smoke (SHS) primarily in 2 settings: homes and cars. Recently, researchers reported that the prevalence of U.S students exposed to SHS in cars decreased from 2000 to 2009; however, comparisons of trends across school levels, gender, and racial/ethnic groups were not assessed. Moreover, no studies have examined trends of exposure to SHS in rooms. We used data from the 2000, 2002, 2004, 2006, and 2009 waves of the National Youth Tobacco Survey, a nationally representative cross-sectional survey of U.S. middle and high school students. For SHS in cars and rooms, we identified exposure trends among nonsmokers from 2000 to 2009 and compared trends across subpopulations with binary logistic regression. We identified significant downward linear trends in SHS in cars and rooms for nearly all measured subpopulations of nonsmoking students from 2000 to 2009. SHS exposure in cars and rooms declined at a significantly greater rate for males than for females. SHS exposure in cars declined at a significantly greater rate for non-Hispanic (NH) Blacks than for NH Whites. SHS exposure in rooms declined at a significantly greater rate for NH Whites than for Hispanics and Native Hawaiians/Pacific Islanders. Although prevalence of exposure to SHS in cars and rooms among nonsmoking U.S. middle and high school students has declined from 2000 to 2009, the rates of decline were not equal across genders and racial/ethnic groups. Identification of these differing rates of exposure can help the public health community advocate for interventions focused on reducing adolescent SHS exposure.

How does electronic cigarette access affect adolescent smoking?

PubMed

Friedman, Abigail S

2015-12-01

Understanding electronic cigarettes' effect on tobacco smoking is a central economic and policy issue. This paper examines the causal impact of e-cigarette access on conventional cigarette use by adolescents. Regression analyses consider how state bans on e-cigarette sales to minors influence smoking rates among 12 to 17 year olds. Such bans yield a statistically significant 0.9 percentage point increase in recent smoking in this age group, relative to states without such bans. Results are robust to multiple specifications as well as several falsification and placebo checks. This effect is both consistent with e-cigarette access reducing smoking among minors, and large: banning electronic cigarette sales to minors counteracts 70 percent of the downward pre-trend in teen cigarette smoking for a given two-year period.

Few reports exist on the association of a public smoking ban with fetal outcomes and maternal smoking in the United States. We sought to evaluate the effect of a citywide smoking ban in comparison to a like municipality with no such ban in Colorado on maternal smoking and subsequent fetal birth outcomes. A citywide smoking ban in Colorado provided a natural experiment. The experimental citywide smoking ban site was implemented in Pueblo, Colorado. A comparison community was chosen that had no smoking ban, El Paso County, with similar characteristics of population, size, and geography. The two sites served as their own controls, as each had a preban and postban retrospective observation period: preban was April 1, 2001, to July 1, 2003; postban was April 1, 2004, to July 1, 2006. Outcomes were maternal smoking (self-report), low birth weight (LBW) (defined as <2500 g or as <3000 g), and preterm births (<37 weeks gestation) in singleton births from mothers residing in these cities and reported to the State Department of Public Health. A difference-in-differences estimator was used to account for site and temporal trends in multivariate models. Compared to El Paso County preban, the odds of maternal smoking and preterm births were, respectively, 38% (p<0.05) and 23% (p<0.05) lower in Pueblo. The odds for LBW births decreased by 8% for <3000 g and increased by 8.4% for <2500 g; however, neither was significant. This is the first evidence in the United States that population-level intervention using a smoking ban improved maternal and fetal outcomes, measured as maternal smoking and preterm births.

In recent decades the overall smoking prevalence in the US has fallen steadily. This study examines whether the same trend is seen in the Medicaid population. National Health Interview Survey (NHIS) data from 17 consecutive annual surveys from 1997 to 2013 (combined N = 514,043) were used to compare smoking trends for 4 insurance groups: Medicaid, the Uninsured, Private Insurance, and Other Coverage. Rates of chronic disease and psychological distress were also compared. Adjusted smoking prevalence showed no detectable decline in the Medicaid population (from 33.8% in 1997 to 31.8% in 2013, trend test P = 0.13), while prevalence in the other insurance groups showed significant declines (38.6%-34.7% for the Uninsured, 21.3%-15.8% for Private Insurance, and 22.6%-16.8% for Other Coverage; all P's<0.005). Among individuals who have ever smoked, Medicaid recipients were less likely to have quit (38.8%) than those in Private Insurance (62.3%) or Other Coverage (69.8%; both P's<0.001). Smokers in Medicaid were more likely than those in Private Insurance and the Uninsured to have chronic disease (55.0% vs 37.3% and 32.4%, respectively; both P's<0.01). Smokers in Medicaid were also more likely to experience severe psychological distress (16.2% for Medicaid vs 3.2% for Private Insurance and 7.6% for the Uninsured; both P's<0.001). The high and relatively unchanging smoking prevalence in the Medicaid population, low quit ratio, and high rates of chronic disease and severe psychological distress highlight the need to focus on this population. A targeted and sustained campaign to help Medicaid recipients quit smoking is urgently needed.

OBJECTIVES: The authors examined trends and predictors of public support for smoke-free restaurants in Massachusetts. METHODS: Since 1992, the Massachusetts Behavioral Risk Factor Surveillance System has asked survey respondents about their attitudes toward smoking in restaurants. Analyses using data from 1992 to 1999 characterized changes over time in support for smoke-free restaurants and the role of demographic and smoking-related factors in predicting support. RESULTS: During 1992 to 1999, the rate of support for smoke-free restaurants increased from 37.5% to 59.8%, with similar increases among current, former, and never smokers. After adjustment for smoking status, support was associated with socioeconomic characteristics, race/ethnicity, and household smoking rules. Among current smokers, lighter smokers and those who were trying to quit were more likely to endorse smoke-free restaurants. CONCLUSIONS: There has been a substantial increase in support for smoke-free restaurants among both smokers and nonsmokers in Massachusetts. PMID:11211644

Abstract Aims This paper estimates how far monthly changes in prevalence of cigarette smoking, motivation to quit and attempts to stop smoking have been associated with changes in prevalence of high‐risk drinking, and motivation and attempts to reduce alcohol consumption in England. Design Data were used from the Alcohol and Smoking Toolkit Studies between April 2014 and June 2016. These involve monthly household face‐to‐face surveys of representative samples of ~1700 adults in England. Measurements Autoregressive Integrated Moving Average with Exogeneous Input (ARIMAX) modelling was used to assess the association over time between monthly prevalence of (a) smoking and high‐risk drinking; (b) high motivation to quit smoking and high motivation to reduce alcohol consumption; and (c) attempts to quit smoking and attempts to reduce alcohol consumption. Findings Mean smoking prevalence over the study period was 18.6% and high‐risk drinking prevalence was 13.0%. A decrease of 1% of the series mean smoking prevalence was associated with a reduction of 0.185% of the mean prevalence of high‐risk drinking 2 months later [95% confidence interval (CI) = 0.033 to 0.337, P = 0.017]. A statistically significant association was not found between prevalence of high motivation to quit smoking and high motivation to reduce alcohol consumption (β = 0.324, 95% CI = –0.371 to 1.019, P = 0.360) or prevalence of attempts to quit smoking and attempts to reduce alcohol consumption (β = −0.026, 95% CI = –1.348 to 1.296, P = 0.969). Conclusion Between 2014 and 2016, monthly changes in prevalence of smoking in England were associated positively with prevalence of high‐risk drinking. There was no significant association between motivation to stop and motivation to reduce alcohol consumption, or attempts to quit smoking and attempts to reduce alcohol consumption. PMID:28556467

The intersection between gender and class can aid in understanding gender differences in smoking. To analyse how changes in gender inequality relate to differences in smoking prevalence by gender, education and birth cohort in Spain over the past five decades (1960-2010). The Gender Inequality Index (GII) was calculated in 5-year intervals from 1960 to 2010. GII ranges from 0 to 1 (1=highest inequality) and encompasses three dimensions: reproductive health, empowerment and labour market. Estimates of female and male smoking prevalence were reconstructed from representative National Health Surveys and stratified by birth cohort and level of education. We calculated female-to-male smoking ratios from 1960 to 2010 stratified by education and birth cohort. Gender inequality in Spain decreased from 0.65 to 0.09 over the past 50 years. This rapid decline was inversely correlated (r=-0.99) to a rising female-to-male smoking ratio. The youngest birth cohort of the study (born 1980-1990) and women with high education levels had similar smoking prevalences compared with men. Women with high levels of education were also the first to show a reduction in smoking prevalence, compared with less educated women. Gender inequality fell significantly in Spain over the past 50 years. This process was accompanied by converging trends in smoking prevalence for men and women. Smoking prevalence patterns varied greatly by birth cohort and education levels. Countries in earlier stages of the tobacco epidemic should consider gender-sensitive tobacco control measures and policies. Published by the BMJ Publishing Group Limited.

In 2003, the Netherlands introduced tobacco control policies, including bans on tobacco sales to minors, advertising and sponsoring and tobacco sales in government institutions. We examined the extent to which these policies were associated with a change in educational inequalities in adolescent smoking. Repeated cross-sectional survey. The Netherlands, 1992-2011. A total of 43 527 14-19-year-old adolescents. Data were obtained from the national Youth Smoking Monitor. We used logistic regression analyses to model the immediate change in daily smoking prevalence in 2003, the trends and the changes in trends. Models included interactions between educational level (high versus low, based on the educational track of the respondent) and, respectively, period (after versus before 2003), time and time × period. Before 2003 the smoking trend declined slightly, and the decline was comparable for students of both high and low educational levels. Immediately after tobacco policies were introduced, daily smoking prevalence dropped for the total population [regression coefficient (β) = -0.340, 95% confidence interval (CI) = -0.445; -0.236]. This drop was larger for high educational level compared to low educational level (β interaction = -0.400, 95% CI = -0.623; -0.176). After 2003, trends in educational inequalities in smoking stabilized. Following the introduction of new tobacco control policies in the Netherlands in 2003, smoking prevalence rates decreased among adolescents of both higher and lower educational levels. However, socio-economic inequalities in adolescent smoking increased. © 2014 Society for the Study of Addiction.

Smoking cessation and bone healing: optimal cessation timing.

Smoking is a worldwide epidemic. Complications related to smoking behavior generate an economic loss around $193 billion annually. In addition to impacting chronic health conditions, smoking is linked to increased perioperative complications in those with current or previous smoking history. Numerous studies have demonstrated more frequent surgical complications including higher rates of infection, poor wound healing, heightened pain complaints, and increased pulmonary morbidities in patients with a smoking history. Longer preoperative cessation periods also seem to correlate with reduced rates. At roughly 4 weeks of cessation prior to surgery, complication rates more closely reflect individuals without a smoking history in comparison with those that smoke within 4 weeks of surgery. In the musculoskeletal system, a similar trend has been observed in smokers with higher rates of fractures, nonunions, malunions, infections, osteomyelitis, and lower functional scores compared to non-smoking patients. Unfortunately, the present literature lacks robust data suggesting a temporal relationship between smoking cessation and bone healing. In our review, we analyze pseudoarthrosis rates following spinal fusion to suggest that bone healing in the context of smoking behavior follows a similar time sequence as observed in wound healing. We also discuss the implications for further clarity on bone healing and smoking cessation within orthopedics including improved risk stratification and better identification of circumstances where adjunct therapy is appropriate.

An investigation of smoke generation during the burning of natural and synthetic solid materials (relevant to fire safety problems), under simulated fire conditions, is presented. Smoke formation mechanisms, including flaming and nonflaming combustion, are reviewed, and the complex physical, chemical, and electrical processes, important in smoke particulate production, are identified. With reference to the smoke formation mechanisms, measured experimental data are discussed, and include effects of ventilation gas temperature, dependence on material composition, and chemical analysis of smoke particulates. Significant differences in smoke characteristics are observed between flaming and nonflaming conditions, which is attributed to specific differences in controlling mechanisms and resultant ways leading to particulate formation. The effects of polymer substrate properties and effects of additives for a given substrate on smoke properties are also discussed in terms of basic processes. It is shown that many of the measured trends can be interpreted by considering postulated mechanisms of particulate formation.

Tobacco smoking is a major worldwide cause of morbidity and mortality from various diseases, including urologic diseases. We reviewed, at global and regional levels, the prevalence and trends of tobacco smoking and legislative and regulatory efforts around tobacco control. We also provided information about electronic cigarette (e-cigarette) use. We used several sources to present the most up-to-date information from national surveys, including the Global Adult Tobacco Survey, the Global Tobacco Control Report, and the Global Youth Tobacco Survey. Smoking prevalence has been decreasing globally, although trends in smoking vary substantially across countries and by gender. Among men, smoking prevalence in most high-income countries started to decrease in the mid-1990s, followed after a few decades by generally smaller decreases in some low- and middle-income countries (LMICs). However, there has been no change, or there has even been an increase, in smoking prevalence in many other LMICs. Countries with the highest male smoking prevalence are located in East Asia, Southeast Asia, and Eastern Europe. Similar to men, smoking prevalence for women has been decreasing in most high-income countries and some LMICs, although the decrease began later and was slower than that for men. Except in a few countries, smoking is much less common for women than for men. Most countries with the highest smoking prevalence in women are in Europe. Countries that have implemented the best practices for tobacco control, including monitoring, smoke-free policies, cessation programs, health warnings, advertising bans, and taxation, have been able to reduce smoking rates and related harms. E-cigarette use has rapidly increased since its introduction to the market. Health care providers should advise smoking patients about quitting smoking. Countries must improve the implementation and enforcement of tobacco control policies. Particular attention should be paid to preventing an increase in

Fire and smoke retardants

Drews, M. J.

Despite a reduction in Federal regulatory activity, research concerned with flame retardancy and smoke suppression in the private sector appears to be increasing. This trend seem related to the increased utilization of plastics for end uses which traditionally have employed metal or wood products. As a result, new markets have appeared for thermally stable and fire resistance thermoplastic materials, and this in turn has spurred research and development activity. In addition, public awareness of the dangers associated with fire has increased as a result of several highly publicized hotel and restaurant fires within the past two years. The consumers recognition of flammability characteristics as important materials property considerations has increased. The current status of fire and smoke retardant chemistry and research are summarized.

Background In recent decades the overall smoking prevalence in the US has fallen steadily. This study examines whether the same trend is seen in the Medicaid population. Methods and findings National Health Interview Survey (NHIS) data from 17 consecutive annual surveys from 1997 to 2013 (combined N = 514,043) were used to compare smoking trends for 4 insurance groups: Medicaid, the Uninsured, Private Insurance, and Other Coverage. Rates of chronic disease and psychological distress were also compared. Results Adjusted smoking prevalence showed no detectable decline in the Medicaid population (from 33.8% in 1997 to 31.8% in 2013, trend test P = 0.13), while prevalence in the other insurance groups showed significant declines (38.6%-34.7% for the Uninsured, 21.3%-15.8% for Private Insurance, and 22.6%-16.8% for Other Coverage; all P’s<0.005). Among individuals who have ever smoked, Medicaid recipients were less likely to have quit (38.8%) than those in Private Insurance (62.3%) or Other Coverage (69.8%; both P’s<0.001). Smokers in Medicaid were more likely than those in Private Insurance and the Uninsured to have chronic disease (55.0% vs 37.3% and 32.4%, respectively; both P’s<0.01). Smokers in Medicaid were also more likely to experience severe psychological distress (16.2% for Medicaid vs 3.2% for Private Insurance and 7.6% for the Uninsured; both P’s<0.001). Conclusions The high and relatively unchanging smoking prevalence in the Medicaid population, low quit ratio, and high rates of chronic disease and severe psychological distress highlight the need to focus on this population. A targeted and sustained campaign to help Medicaid recipients quit smoking is urgently needed. PMID:28542637

In 2009, the FDA required a black box warning (BBW) on bupropion and varenicline, the two commonly prescribed smoking cessation agents due to reports of adverse neuropsychiatric events. We investigated if there was a decline in use of bupropion and varenicline after the BBW by comparing the percent using these medications before and after BBW. We conducted a retrospective observational study using data from the Medical Expenditure Panel Survey from 2007 to 2014. The study sample consisted of adult smokers, who were advised by their physicians to quit smoking. We divided the time period into "pre-warning", "post-warning: immediate", and "post-warning: late." Unadjusted analysis using chi-square tests and adjusted analyses using logistic regressions were conducted to evaluate the change in bupropion and varenicline use before and after the BBW. Secondary analyses using piecewise regression were also conducted. On an average, 49.04% of smokers were advised by their physicians to quit smoking. We observed a statistically significant decline in varenicline use from 22.1% in year 2007 to 9.23% in 2014 (p value<0.001). In the logistic (Adjusted Odds Ratio=0.36, 95% CI=0.22-0.58) and piecewise regressions (Odds Ratio=0.64, 95% CI=0.41-0.99) smokers who were advised to quit smoking by their physicians were less likely to use varenicline in the immediate post-BBW period as compared to pre-BBW period. While the use of varenicline continued to be significantly low in the late post-BBW period (AOR=0.45, 95% CI=0.31-0.64) as compared to the pre-BBW period, the trend in use as seen in piecewise regression remained stable (OR=0.90, 95% CI=0.75-1.06). We did not observe significant differences in bupropion use between the pre- and post-BBW periods. The passage of the FDA boxed warning was associated with a significant decline in the use of varenicline, but not in the use of bupropion. Copyright © 2017 Elsevier B.V. All rights reserved.

Hurricane Katrina: addictive behavior trends and predictors.

2011-01-01

Post-disaster trends in alcohol consumption and cigarette smoking, as well as their predictors, were identified. Methods. Data from cross-sectional and panel surveys of African American adults in New Orleans, Louisiana, were used from before (2004: n = 1,867; 2005: n = 879) and after (2006a: n = 500; 2006b: n = 500) Hurricane Katrina. Alcohol consumption increased significantly from pre- to post-Hurricane Katrina, while cigarette smoking remained constant. In 2006, posttraumatic stress disorder (PTSD) was associated with cigarette smoking, whereas "news attention" and "provided social support" were inversely associated with cigarette smoking. "News attention" was also inversely associated with cigarette smoking frequency, while "neighborliness" was associated with alcohol consumption. In addition, the effects of PTSD on alcohol consumption were moderated by "neighborliness." In the wake of Hurricane Katrina, there were complex predictive processes of addictive behaviors involving PTSD, news information, and social capital-related measures.

To determine the effect of municipal smoke-free laws in Kentucky on gross and/or net revenues from charitable gaming activities. Between January 2000 and June 2007, 13 Kentucky communities implemented smoke-free legislation; only three specifically exempted charitable gaming facilities and compliance in several communities was not consistent. Kentucky is a tobacco-growing state that has the highest smoking rate in the United States. A fixed-effects time series design to estimate the impact of municipal smoke-free laws on charitable gaming. 13 Kentucky counties that implemented smoke-free laws during the study period of January 2000 through June 2007. All charitable gaming facilities in 13 counties in which a smoke-free ordinance was enacted during the study period. Gross and net revenues from charitable gaming activities in each county for each quarter of the study period, obtained from the Kentucky Department of Charitable Gaming. When controlling for economic variables, county-specific effects and time trends using a robust statistical framework, there was no significant relation between smoke-free laws and charitable gaming revenues. Municipal smoke-free legislation had no effect on charitable gaming revenues. No significant harm to charitable gaming revenues was associated with the smoke-free legislation during the 7.5-year study period, despite the fact that Kentucky is a tobacco-producing state with higher-than-average smoking rates.

The Effect of Cigarette Smoking on Musculoskeletal-Related Disability

Background This study describes cigarette smoking’s effect on development of physical disability following initial musculoskeletal-related hospitalization. Methods We followed 15,140 US Army personnel hospitalized for common musculoskeletal disorders between 1989–1996 for up to 8 years (1997) to assess risk for long-term physical disability. Results Trends between increased smoking level and long-term disability were identified for persons with knee injuries, rotator cuff injuries, and intervertebral disc displacement. In proportional hazards models, disability was significantly associated with heavy smoking among all subjects (relative hazard (RH) = 1.21). Both heavy smokers (RH = 1.49) and light to moderate smokers (RH = 1.44) were at greater risk for disability following meniscal injuries. Excess fraction due to smoking among subjects with meniscal injuries who currently smoke was 38%. Conclusions Findings suggest an association between smoking and development of disability following meniscal injury. Given the high excess fraction of disability associated with smoking, other studies are needed to confirm this association. PMID:12645091

Cigarette smoking has been shown to increase oxidative DNA damage in human sperm cells. Assessment of the role of cigarette smoking in the etiology of childhood cancer has focused primarily on the effect of maternal smoking. Similar studies in relation to paternal smoking, however, have been inconclusive. Few studies have evaluated the effect of paternal smoking in the preconception period, and most of these could not disentangle the effects of paternal from maternal smoking. We investigated the relationship of paternal smoking, particularly in the preconception period, with childhood cancer among offspring of the nonsmoking mothers. We conducted a population-based, case-control study in Shanghai, People's Republic of China, where the prevalence of smoking is high among men but extremely low among women. The study included 642 childhood cancer case patients (<15 years of age) and their individually matched control subjects. Information concerning parental smoking, alcohol drinking, and other exposures of the index child was obtained by direct interview of both parents of the study subjects. Odds ratios (ORs), derived from conditional logistic regression models, were used to measure the association between paternal smoking and risk of childhood cancers. Paternal preconception smoking was related to a significantly elevated risk of childhood cancers, particularly acute leukemia and lymphoma. The risks rose with increasing pack-years of paternal preconception smoking for acute lymphocytic leukemia (ALL) (P for trend = .01), lymphoma (P for trend = .07), and total cancer (P for trend = .006). Compared with children whose fathers had never smoked cigarettes, children whose fathers smoked more than five pack-years prior to their conception had adjusted ORs of 3.8 (95% confidence interval [CI] = 1.3-12.3) for ALL, 4.5 (95% CI = 1.2-16.8) for lymphoma, 2.7 (95% CI = 0.8-9.9) for brain tumors, and 1.7 (95% CI = 1.2-2.5) for all cancers combined.

Few studies have examined the long-term efficacy of computer-based smoking prevention and cessation programs. We analyzed the long-term impact of A Smoking Prevention Interactive Experience (ASPIRE), a theoretically sound computer-based smoking prevention and cessation curriculum for high school students. Sixteen predominantly minority, inner-city high schools were randomly assigned to receive the ASPIRE curriculum or standard care (receipt of the National Cancer Institute's Clearing the Air self-help booklet). A total of 1160 students, 1098 of whom were nonsmokers and 62 smokers at baseline, were included. At 18-month follow-up, among baseline nonsmokers, smoking initiation rates were significantly lower in the ASPIRE condition (1.9% vs. 5.8%, p < .05). Students receiving ASPIRE also demonstrated significantly higher decisional balance against smoking and decreased temptations to smoke. Differences between groups in self-efficacy and resistance skills were not significant. There was a nonsignificant trend toward improved smoking cessation with ASPIRE, but low recruitment of smokers precluded conclusions with respect to cessation. ASPIRE demonstrated the potential for an interactive multimedia program to promote smoking prevention. Further studies are required to determine ASPIRE's effects on cessation.

The aim of the current study is to investigate trends and socioeconomic differences in policy triggers for thinking about quitting in six European countries. Data were derived from all available survey waves of the International Tobacco Control (ITC) Europe Surveys (2003-2013). France conducted three survey waves (n=1420-1735), Germany three waves (n=515-1515), The Netherlands seven waves (n=1420-1668), Ireland three waves (n=582-1071), Scotland two waves (n=461-507), and the rest of the United Kingdom conducted seven survey waves (n=861-1737). Smokers were asked whether four different policies (cigarette price, smoking restrictions in public places, free or lower cost medication, and warning labels on cigarette packs) influenced them to think about quitting. Generalized Estimating Equation (GEE) models were estimated for each country. Cigarette price was mentioned most often in all countries and across all waves as trigger for thinking about quitting. Mentioning cigarette price and warning labels increased after the implementation of price increases and warning labels in some countries, while mentioning smoking restrictions decreased after their implementation in four countries. All studied policy triggers were mentioned more often by smokers with low and/or moderate education and income than smokers with high education and income. The education and income differences did not change significantly over time for most policies and in most countries. Tobacco control policies work as a trigger to increase thoughts about quitting, particularly in smokers with low education and low income and therefore have the potential to reduce health inequalities in smoking.

Effects of market liberalisation on smoking in Japan

PubMed Central

Honjo, K.; Kawachi, I.

2000-01-01

OBJECTIVE—To document the effect of the liberalisation of the Japanese tobacco market on Japanese smoking rates and on Japanese tobacco industry practices.
DATA SOURCE—Asahi Shimbun (major daily newspaper) from 1980 to 1996.
STUDY SELECTION—Review of media coverage on the effects of market liberalisation following the imposition of the USA's section 301 trade sanction.
DATA SYNTHESIS—The opening of Japan's tobacco market to foreign cigarette companies stalled a decline in smoking prevalence. Smoking rates among young women increased significantly, and also appear to be on the rise among adolescents. Aggressive marketing and promotional activities by US and Japanese tobacco companies in response to trade liberalisation appear responsible for these adverse trends. Steep increases in sales through vending machines were also possible contributors to the rising smoking prevalence among adolescents. On the positive side, market liberalisation indirectly promoted smoking control efforts in Japan, by causing an anti-smoking movement to coalesce.
CONCLUSION—Market liberalisation in Japan played a significant role in increasing smoking prevalence among young women and adolescents while helping to transform the issue of smoking in Japan from a matter of individual choice to a public health problem.

Assessing the impact of the national smoking ban in indoor public places in china: evidence from quit smoking related online searches.

PubMed

Huang, Jidong; Zheng, Rong; Emery, Sherry

2013-01-01

Despite the tremendous economic and health costs imposed on China by tobacco use, China lacks a proactive and systematic tobacco control surveillance and evaluation system, hampering research progress on tobacco-focused surveillance and evaluation studies. This paper uses online search query analyses to investigate changes in online search behavior among Chinese Internet users in response to the adoption of the national indoor public place smoking ban. Baidu Index and Google Trends were used to examine the volume of search queries containing three key search terms "Smoking Ban(s)," "Quit Smoking," and "Electronic Cigarette(s)," along with the news coverage on the smoking ban, for the period 2009-2011. Our results show that the announcement and adoption of the indoor public place smoking ban in China generated significant increases in news coverage on smoking bans. There was a strong positive correlation between the media coverage of smoking bans and the volume of "Smoking Ban(s)" and "Quit Smoking" related search queries. The volume of search queries related to "Electronic Cigarette(s)" was also correlated with the smoking ban news coverage. To the extent it altered smoking-related online searches, our analyses suggest that the smoking ban had a significant effect, at least in the short run, on Chinese Internet users' smoking-related behaviors. This research introduces a novel analytic tool, which could serve as an alternative tobacco control evaluation and behavior surveillance tool in the absence of timely or comprehensive population surveillance system. This research also highlights the importance of a comprehensive approach to tobacco control in China.

[Secondhand smoke in hospitality venues. Exposure, body burden, economic and health aspects in conjunction with smoking bans].

PubMed

Fromme, H; Kuhn, J; Bolte, G

2009-04-01

Secondhand smoke was classified by national and international organisations as a known cause of cancer in humans and has many adverse health effects, especially cardiovascular diseases and lung tumours. Global studies have clearly shown that hospitality venues have the highest levels of indoor air pollution containing different substances that are clearly carcinogenic--such as tobacco-related chemicals--compared with other, smoke-free indoor spaces. Data from the human biomonitoring of non-smoking employees in the food service industry confirm this high exposure level. Non-smokers exposed to secondhand smoke in these environments are at increased risk for adverse health effects. The consistent protection of non-smokers in public places such as restaurants and bars through a smoking ban results in a significant reduction of the pollutants in the air (mostly > 90%) and clearly reduces the internal body burden for users and employees. Furthermore, health complaints by non-smoking employees are reduced and the higher risk for lung tumours of employees in the food service industry compared with the general population can be effectively reduced as well. According to current standards of knowledge, other measures such as spatial separation of smoking areas or the use of mechanical venting systems do not achieve a comparably high and effective pollutant reduction under field conditions. Studies concerning the economic effects of prohibiting smoking in public places conducted in various countries have shown that beverage-focused gastronomic enterprises experience a short-term down trend but that food-focused gastronomic enterprises do not experience any negative or even positive effects. The positive effects of a ban on smoking in public places on the general population are a decline in cigarette consumption and the reduction of secondhand smoke exposure by non-smokers. Smoking bans in hospitality venues are not necessarily linked with a shift of the tobacco consumption to

This study quantified the potential reach of Internet smoking cessation interventions to support calculations of potential population impact (reach × effectiveness). Using a nationally representative survey, we calculated the number and proportion of adult smokers that look for cessation assistance online each year. Five waves (2005, 2011, 2013, 2015, 2017) of the National Cancer Institute's Health Information National Trends Survey were examined. The survey asked US adults whether they ever go online to use the Internet, World Wide Web, or email and had used the Internet to look for information about quitting smoking within the past 12 months. We estimated the proportion and number of (1) all US adult smokers, and (2) online US adult smokers that searched for cessation information online. Cross-year comparisons were assessed with logistic regression. The proportion of all smokers who searched online for cessation information increased over the past decade (p < .001): 16.5% in 2005 (95% CI = 13.2% to 20.4%), 20.9% in 2011 (95% CI = 15.55% to 28.0%), 25.6% in 2013 (95% CI = 19.7% to 33.0%), 23.4% in 2015 (95% CI = 16.9% to 31.0%), and 35.9% in 2017 (95% CI = 24.8% to 48.9%). Among online smokers only, approximately one third searched online for cessation information each year from 2005 through 2015. In 2017, that proportion increased to 43.7% (95% CI = 29.7% to 58.7%), when an estimated 12.4 million online smokers searched for cessation help. More than one third of all smokers turn to the Internet for help quitting each year, representing more than 12 million US adults. This research provides contemporary estimates for the reach of Internet interventions for smoking cessation. Such estimates are necessary to estimate the population impact of Internet interventions on quit rates. The research finds more than 12 million US smokers searched online for cessation information in 2017.

Patterns and causes of gender differences in smoking.

PubMed

Waldron, I

1991-01-01

In the early twentieth century in the United States and other Western countries, women were much less likely than men to smoke cigarettes, due in part to widespread social disapproval of women's smoking. During the mid-twentieth century, growing social acceptance of women's smoking contributed to increased smoking adoption by women. Increased social acceptance of women's smoking was part of a general liberalization of norms concerning women's behavior, reflecting increasing equality between the sexes. These historical trends were due in part to increases in women's employment. However, in the contemporary period employment appears to have little or no effect on women's smoking. Sex role norms and general expectations concerning gender-appropriate behavior have had a variety of effects on gender differences in smoking. First, general characteristics of traditional sex roles, including men's greater social power and generally greater restrictions on women's behavior, contributed to widespread social pressures against women's smoking. Second, traditional sex role norms and expectations have fostered gender differences in personal characteristics and experiences which influence smoking adoption. For example, rebelliousness has been more expected and accepted for males, and greater rebelliousness among adolescent males has contributed to greater smoking adoption by males. Finally, certain aspects of sex roles have contributed to gender differences in appraisal of the costs and benefits of smoking. For example, physical attractiveness is emphasized more for females and the contemporary beauty ideal is very slender, so females are more likely to view weight control as a benefit of smoking. Several other hypotheses concerning the causes of gender differences in smoking are not supported by the available evidence. For example, it appears that women's generally greater concern with health has not contributed significantly to gender differences in the prevalence of smoking

Decreases in Smoking-Related Cancer Mortality Rates Are Associated with Birth Cohort Effects in Korean Men.

Background: This study aimed to examine trends in smoking-related cancer mortality rates and to investigate the effect birth cohort on smoking-related cancer mortality in Korean men. Methods: The number of smoking-related cancer deaths and corresponding population numbers were obtained from Statistics Korea for the period 1984-2013. Joinpoint regression analysis was used to detect changes in trends in age-standardized mortality rates. Birth-cohort specific mortality rates were illustrated by 5 year age groups. Results: The age-standardized mortality rates for oropharyngeal decreased from 2003 to 2013 (annual percent change (APC): -3.1 (95% CI, -4.6 to -1.6)) and lung cancers decreased from 2002 to 2013 (APC -2.4 (95% CI -2.7 to -2.2)). The mortality rates for esophageal declined from 1994 to 2002 (APC -2.5 (95% CI -4.1 to -0.8)) and from 2002 to 2013 (APC -5.2 (95% CI -5.7 to -4.7)) and laryngeal cancer declined from 1995 to 2013 (average annual percent change (AAPC): -3.3 (95% CI -4.7 to -1.8)). By the age group, the trends for the smoking-related cancer mortality except for oropharyngeal cancer have changed earlier to decrease in the younger age group. The birth-cohort specific mortality rates and age-period-cohort analysis consistently showed that all birth cohorts born after 1930 showed reduced mortality of smoking-related cancers. Conclusions: In Korean men, smoking-related cancer mortality rates have decreased. Our findings also indicate that current decreases in smoking-related cancer mortality rates have mainly been due to a decrease in the birth cohort effect, which suggest that decrease in smoking rates.

Exposure to secondhand smoke (SHS) from cigarettes poses a significant health risk to nonsmokers. Among youth, the home is the primary source of SHS. However, little is known about youth exposure to SHS in other nonpublic areas, particularly motor vehicles. Data were obtained from the 2000, 2002, 2004, 2006, and 2009 waves of the National Youth Tobacco Survey, a nationally representative survey of US students in grades 6 to 12. Trends in SHS exposure in a car were assessed across survey years by school level, gender, and race/ethnicity by using binary logistic regression. From 2000 to 2009, the prevalence of SHS exposure in cars declined significantly among both nonsmokers (39.0%-22.8%; trend P < .001) and smokers (82.3%-75.3%; trend P < .001). Among nonsmokers, this decline occurred across all school level, gender, and race/ethnicity subgroups. SHS exposure in cars decreased significantly among US middle and high school students from 2000 to 2009. Nevertheless, in 2009, over one-fifth of nonsmoking students were exposed to SHS in cars. Jurisdictions should expand comprehensive smoke-free policies that prohibit smoking in worksites and public places to also prohibit smoking in motor vehicles occupied by youth.

Background: University students worldwide seem to have increased rates of smoking, alcohol abuse, binge drinking episodes and harmful consumption trends, raising a serious public health issue. The aim of the present study was to investigate university students’ smoking habits and exposure to secondary smoke amid a financial crisis. Methods: The present descriptive, correlational analysis was conducted at the University of Peloponnese. Results: The average age of the sample (n=203) was 24.9 years (±7.6 years) with 36.0% of the participants (n=73) being postgraduate students. Some 51.2% (n=104) of the participants said they didn’t smoke and 46.3% (n=94, p=0.003) reported no secondary smoke exposure during the past week at home. The majority of the remainder initiated smoking at age 16-17 (48.5%, n=48), and 64.6% (n=42) said the financial crisis did not lead them to change their smoking habits. Conclusions: The majority of students support smoking ban laws in enclosed public spaces, but also their replies highlighted poor implementation on behalf of the state and the authorities. The financial crisis did not appear to have affected student smoking habits. PMID:28610966

The meanings of smoking to women and their implications for cessation.

PubMed

Greaves, Lorraine

2015-01-27

Smoking cigarettes is a gendered activity with sex- and gender-specific uptake trends and cessation patterns. While global male smoking rates have peaked, female rates are set to escalate in the 21st century, especially in low and middle income countries. Hence, smoking cessation for women will be an ongoing issue and requires refreshed attention. Public health and health promotion messages are being challenged to be increasingly tailored, taking gender into account. Women-centred approaches that include harm-reduction, motivational interviewing and trauma-informed elements are the new frontiers in interventions to encourage smoking cessation for women. Such approaches are linked to the meanings of smoking to women, the adaptive function of, and the overall role of smoking cigarettes in the context of women's lives. These approaches respect gender and sex-related factors that affect smoking and smoking cessation and respond to these issues, not by reinforcing destructive or negative gender norms, but with insight. This article discusses a women-centred approach to smoking cessation that could underpin initiatives in clinical, community or public health settings and could inform campaigns and messaging.

Policies restricting indoor worksite tobacco use began being implemented more than a decade ago. More recently, the scope of these policies has been expanding to outdoors, with hospitals leading the trend in restricting smoking throughout their grounds. However, research on the effects such bans have on employees is scarce. The purpose of the current study was to examine the impact of a campus-wide smoking ban on employees and patients at a cancer center. Employees completed anonymous questionnaires during the months before (n = 607; 12% smokers) and 3 months after the ban implementation (n = 511; 10% smokers). Patients (n = 278; 23% smokers) completed an anonymous questionnaire preban. Results showed that 86% of nonsmokers, 20% of employees who smoke, and 57% of patients who smoke supported the ban. More than 70% of smokers were planning or thinking about quitting at both time points and nearly one-third were interested in cessation services following the ban. Before the ban, 32% expected the ban to have a negative effect on job performance and 41% thought their smoking before and after work would increase. Postban, 22% reported a negative impact on job performance, 35% increased smoking before and after work, and 7% quit. Overall, these data revealed an overwhelming support for an outdoor smoking ban by nonsmoker employees and patients. Although a majority of employee smokers opposed the ban, a significant proportion was interested in cessation. Compared with preban expectations, a lower proportion experienced negative effects postban. Findings suggest a need for worksite cessation programs to capitalize on the window of opportunity created by tobacco bans, while also addressing concerns about effects on work performance.

Background Approximately 50% of smokers die prematurely from tobacco-related diseases. In July 2006, the Massachusetts health care reform law mandated tobacco cessation coverage for the Massachusetts Medicaid population. The new benefit included behavioral counseling and all medications approved for tobacco cessation treatment by the U.S. Food and Drug Administration (FDA). Between July 1, 2006 and December 31, 2008, a total of 70,140 unique Massachusetts Medicaid subscribers used the newly available benefit, which is approximately 37% of all Massachusetts Medicaid smokers. Given the high utilization rate, the objective of this study is to determine if smoking prevalence decreased significantly after the initiation of tobacco cessation coverage. Methods and Findings Smoking prevalence was evaluated pre- to post-benefit using 1999 through 2008 data from the Massachusetts Behavioral Risk Factor Survey (BRFSS). The crude smoking rate decreased from 38.3% (95% C.I. 33.6%–42.9%) in the pre-benefit period compared to 28.3% (95% C.I.: 24.0%–32.7%) in the post-benefit period, representing a decline of 26 percent. A demographically adjusted smoking rate showed a similar decrease in the post-benefit period. Trend analyses reflected prevalence decreases that accrued over time. Specifically, a joinpoint analysis of smoking prevalence among Massachusetts Medicaid benefit-eligible members (age 18–64) from 1999 through 2008 found a decreasing trend that was coincident with the implementation of the benefit. Finally, a logistic regression that controlled for demographic factors also showed that the trend in smoking decreased significantly from July 1, 2006 to December 31, 2008. Conclusion These findings suggest that a tobacco cessation benefit that includes coverage for medications and behavioral treatments, has few barriers to access, and involves broad promotion can significantly reduce smoking prevalence.

Promotion of a healthy lifestyle and non-pharmacological interventions in the treatment of chronic obstructive pulmonary disease (COPD) has received great attention in recent decades. The aim of this study was to investigate trends in leisure time physical activity (PA), smoking, alcohol consumption and body mass index (BMI) from 2000 to 2010 in Danish individuals with and without COPD. Analyses were based on data provided by The Danish Health and Morbidity's three cross-sectional surveys from 2000, 2005 and 2010. Data compromised level of leisure time PA, smoking, alcohol consumption, BMI and sociodemographic characteristics. Participants aged 25 years or older with and without COPD were included in the analyses. In multiple logistic regression analyses, odds ratio (OR) of being physically active in the leisure time in 2010 compared to 2000 was 1.70 (95 % CI: 1.28-2.26), p < 0.001, and 1.32 (1.22-1.43), p < 0.001, in participants with and without COPD, respectively. Being a non-smoker in 2010 compared to 2000 was associated with an OR of 1.41 (1.07-1.85), p = 0.015, and 1.73 (1.63-1.85), p < 0.001, in participants with and without COPD. The OR of not exceeding national recommended alcohol limits was 0.64 (0.45-0.93), p = 0.020, and 1.19 (1.09-1.29), p < 0.001, in participants with and without COPD. In a multiple linear regression analysis, the time frame from 2000 to 2010 was associated with an increased BMI of 1.18 kg · m(-2) (0.52-1.84), p < 0.001, and 0.74 kg · m(-2) (0.63-0.86), p < 0.001, in participants with and without COPD. The COPD participants with higher levels of education and/or living in a marriage or a relationship were more likely to be physically active, non-smoking and not exceeding the recommended alcohol limits. From the 2000 to 2010, Danish individuals aged 25 years with and without COPD, increased their leisure time PA level and reduced smoking. Lower socioeconomic status was associated with a

Our objective was to examine factors associated with compliance and support for a smoke-free campus before and after a 1995 campus-wide smoking ban for everyone, including teachers and visitors, in California. Adolescent (12-17 years) data from the 1993, 1996, 1999 and 2002 (N approximately 6000 each year) California Tobacco Surveys (population-based telephone surveys) were analyzed. Trends in compliance with smoke-free school policies and support for smoke-free campuses were examined among students in public and private schools. Perceived compliance with the no-smoking rule by most or all student smokers increased from 43.7 +/- 1.6% in 1993 to 71.5 +/- 1.4% in 2002. While non-smokers have overwhelmingly favored smoke-free school grounds since 1993 (more than 85% each survey year), support among current smokers increased from 55.8 +/- 4.7% in 1996 to 69.1 +/- 6.8% in 2002. Student smokers who saw teachers smoking in school were less likely to favor school smoking bans (odds ratio = 0.25, 95% confidence interval 0.12-0.49). The percentage of private school students seeing teachers smoke on school grounds has been at least twice that of public school students since 1996. Compliance with and support for smoke-free schools increased since smoking was banned on campus for everyone. Perceived compliance by teachers, much lower in private schools, appears to undermine student smokers' support of this policy. Increased efforts are necessary to communicate to teachers the importance of their modeling of policy compliance to students.

Smoking increases HIV-related and non-HIV-related morbidity and mortality for persons with HIV infection. We estimated changes in cigarette smoking among adults with HIV and adults in the general U.S. population from 2009 to 2014 to inform HIV smoking cessation programs. Among HIV-positive adults, rates of current smoking declined from 37.6% (confidence interval [CI]: 34.7-40.6) in 2009 to 33.6% (CI: 29.8-37.8) in 2014. Current smoking among U.S. adults declined from 20.6% (CI: 19.9-21.3) in 2009 to 16.8% (CI: 16.2-17.4) in 2014. HIV-positive adults in care were significantly more likely to be current smokers compared with the general U.S. population; they were also less likely to quit smoking. For both HIV-positive adults in care and the general population, disparities were noted by racial/ethnic, educational level, and poverty-level subgroups. For most years, non-Hispanic blacks, those with less than high school education, and those living below poverty level were more likely to be current smokers and less likely to quit smoking compared with non-Hispanic whites, those with greater than high school education, and those living above poverty level, respectively. To decrease smoking-related causes of illness and death and to decrease HIV-related disparities, smoking cessation interventions are vital as part of routine care with HIV-positive persons. Clinicians who care for HIV-positive persons who smoke should utilize opportunities to discuss and implement smoking cessation strategies during routine clinical visits. Published by Elsevier Inc.

Tobacco use continues to be the leading global cause of preventable death. Understanding the trends in prevalence of cigarette smoking and smoking behaviors among adolescents enables physicians to target prevention resources more effectively. The objectives of this study were to monitor the prevalence of smoking, to compare the prevalence of smoking in subgroups of region, gender and age, and to explore smoking behavior among adolescent smokers. The International Tobacco Control Survey-Thailand is a population-based, national representative, longitudinal survey conducted among adolescents between the ages of 13-17. Adolescents were sampled from Bangkok and 4 regions of Thailand using stratified multistage sampling. Three surveys were conducted during January 2005 to March 2008. Respondents were asked to complete self-administered questionnaires. Data was analyzed using descriptive statistics. Overall, smoking prevalence has increased from 12.0% in wave 1 to 14.3% in wave 2 and 18.3% in wave 3. Smoking prevalence in males was more than 10 times higher than females. Manufactured cigarettes were most frequently used by adolescents. More than 70% of smokers reported that they smoked manufactured cigarettes. Total amount of tobacco use per day increased from wave 1 to wave 3. The proportion of smokers who reported that they bought cigarettes by themselves increased during the follow-up waves (38.3%, 60.9%, 68.2% respectively). More than 20% of smokers reported that they never plan to quit smoking. Smoking prevalence among thai adolescents was apparently increased.

The incentives created by a harm reduction approach to smoking cessation: Snus and smoking in Sweden and Finland.

PubMed

Maki, Jennifer

2015-06-01

Tobacco harm reduction involves advocating the use of a less harmful alternative to smoking for those users who are unwilling or unable to quit. The net effect of such an approach is unclear as it may create opposing incentives. Although some smokers may substitute toward this less harmful alternative, it may reduce the incentive to quit by undermining public health efforts and may act as a gateway to smoking. This research paper aims to answer the question: Does the availability of a less harmful alternative to smoking lead to cessation? To explore the opposing incentives created by a harm reduction approach to smoking cessation, I focus on the role of snus, a popular smokeless tobacco product in Scandinavia that is widely used in Sweden. This paper exploits a quasi-natural experiment to examine the net effect resulting from these opposing incentives. While two Scandinavian countries, Sweden and Finland, joined the European Union (EU) in 1995, Finland was subject to a pre-existing EU ban on oral tobacco products while Sweden received an exemption. A difference in differences framework is used to estimate the change in the smoking rate in Finland due to the implementation of the ban. A secondary analysis uses Finnish smoking data to test for a structural break in trend. In the post-ban period, smoking was 3.47 percentage points higher in Finland relative to what it would have been in the absence of the ban. The availability of snus, a less harmful alternative to smoking, appears to have had a positive impact (reduction) on the smoking rate. Offering acceptable alternatives to cigarettes is critical in reducing smoking prevalence. Copyright © 2014 Elsevier B.V. All rights reserved.

Raising the tobacco sales age to 21 has gained support as a promising strategy to reduce youth cigarette access, but there is little direct evidence of its impact on adolescent smoking. Using regional youth survey data, we compared youth smoking trends in Needham, Massachusetts--which raised the minimum purchase age in 2005--with those of 16 surrounding communities. The MetroWest Adolescent Health Survey is a biennial census survey of high school youth in communities west of Boston; over 16,000 students participated at each of four time points from 2006 to 2012. Using these pooled cross-section data, we used generalised estimating equation models to compare trends in current cigarette smoking and cigarette purchases in Needham relative to 16 comparison communities without similar ordinances. To determine whether trends were specific to tobacco, we also examined trends in youth alcohol use over the same time period. From 2006 to 2010, the decrease in 30-day smoking in Needham (from 13% to 7%) was significantly greater than in the comparison communities (from 15% to 12%; p<.001). This larger decline was consistent for both genders, Caucasian and non-Caucasian youth, and grades 10, 11 and 12. Cigarette purchases among current smokers also declined significantly more in Needham than in the comparison communities during this time. In contrast, there were no comparable differences for current alcohol use. Our results suggest that raising the minimum sales age to 21 for tobacco contributes to a greater decline in youth smoking relative to communities that did not pass this ordinance. These findings support local community-level action to raise the tobacco sales age to 21. Published by the BMJ Publishing Group Limited.

Very little is known about the prevalence, patterns, social norms, and trends of smoking among students attending historically Black colleges and universities (HBCUs). The current study assessed the prevalence, patterns, and norms associated with cigarette smoking among a cross-sectional random sample of 371 undergraduate college students at a historically Black university in North Carolina. Eighty-seven percent of the respondents were non-smokers. Eighty-six percent of the students reported that smoking was discouraged among their peers and 45% responded that they preferred associating with peers who did not smoke cigarettes. Seventy-one percent of the students responded that they did not smoke before the age of 18 and 55% reported that, while they were growing up, neither of their parents smoked. Preliminary findings of this study indicate that smoking is not widely practiced and has not become a socially acceptable or encouraged norm among college students attending an HBCU.

Assessing the Impact of the National Smoking Ban in Indoor Public Places in China: Evidence from Quit Smoking Related Online Searches

2013-01-01

Background Despite the tremendous economic and health costs imposed on China by tobacco use, China lacks a proactive and systematic tobacco control surveillance and evaluation system, hampering research progress on tobacco-focused surveillance and evaluation studies. Methods This paper uses online search query analyses to investigate changes in online search behavior among Chinese Internet users in response to the adoption of the national indoor public place smoking ban. Baidu Index and Google Trends were used to examine the volume of search queries containing three key search terms “Smoking Ban(s),” “Quit Smoking,” and “Electronic Cigarette(s),” along with the news coverage on the smoking ban, for the period 2009–2011. Findings Our results show that the announcement and adoption of the indoor public place smoking ban in China generated significant increases in news coverage on smoking bans. There was a strong positive correlation between the media coverage of smoking bans and the volume of “Smoking Ban(s)” and “Quit Smoking” related search queries. The volume of search queries related to “Electronic Cigarette(s)” was also correlated with the smoking ban news coverage. Interpretation To the extent it altered smoking-related online searches, our analyses suggest that the smoking ban had a significant effect, at least in the short run, on Chinese Internet users’ smoking-related behaviors. This research introduces a novel analytic tool, which could serve as an alternative tobacco control evaluation and behavior surveillance tool in the absence of timely or comprehensive population surveillance system. This research also highlights the importance of a comprehensive approach to tobacco control in China. PMID:23776504

Decreases in Smoking-Related Cancer Mortality Rates Are Associated with Birth Cohort Effects in Korean Men

2016-01-01

Background: This study aimed to examine trends in smoking-related cancer mortality rates and to investigate the effect birth cohort on smoking-related cancer mortality in Korean men. Methods: The number of smoking-related cancer deaths and corresponding population numbers were obtained from Statistics Korea for the period 1984–2013. Joinpoint regression analysis was used to detect changes in trends in age-standardized mortality rates. Birth-cohort specific mortality rates were illustrated by 5 year age groups. Results: The age-standardized mortality rates for oropharyngeal decreased from 2003 to 2013 (annual percent change (APC): −3.1 (95% CI, −4.6 to −1.6)) and lung cancers decreased from 2002 to 2013 (APC −2.4 (95% CI −2.7 to −2.2)). The mortality rates for esophageal declined from 1994 to 2002 (APC −2.5 (95% CI −4.1 to −0.8)) and from 2002 to 2013 (APC −5.2 (95% CI −5.7 to −4.7)) and laryngeal cancer declined from 1995 to 2013 (average annual percent change (AAPC): −3.3 (95% CI −4.7 to −1.8)). By the age group, the trends for the smoking-related cancer mortality except for oropharyngeal cancer have changed earlier to decrease in the younger age group. The birth-cohort specific mortality rates and age-period-cohort analysis consistently showed that all birth cohorts born after 1930 showed reduced mortality of smoking-related cancers. Conclusions: In Korean men, smoking-related cancer mortality rates have decreased. Our findings also indicate that current decreases in smoking-related cancer mortality rates have mainly been due to a decrease in the birth cohort effect, which suggest that decrease in smoking rates.

The association of dietary fiber intake with colorectal cancer risk is established. However, the association may differ between cigarette smokers and nonsmokers. We evaluated this hypothesis in a large colonoscopy-based case-control study. Dietary fiber intakes were estimated by self-administered food frequency questionnaire. Unconditional logistic regression analysis was used to estimate ORs and 95% CIs with adjustment for potential confounders. Analysis also was stratified by cigarette smoking and sex. High dietary fiber intake was associated with reduced risk of colorectal polyps (P-trend = 0.003). This association was found to be stronger among cigarette smokers (P-trend = 0.006) than nonsmokers (P-trend = 0.21), although the test for multiplicative interaction was not statistically significant (P = 0.11). This pattern of association was more evident for high-risk adenomatous polyps (ADs), defined as advanced or multiple ADs (P-interaction smoking and dietary fiber intake = 0.09). Among cigarette smokers who smoked ≥23 y, a 38% reduced risk of high-risk ADs was found to be associated with high intake of dietary fiber compared with those in the lowest quartile fiber intake group (P-trend = 0.004). No inverse association with dietary fiber intake was observed for low-risk ADs, defined as single nonadvanced ADs. Cigarette smoking may modify the association of dietary fiber intake with the risk of colorectal polyps, especially high-risk ADs, a well-established precursor of colorectal cancer.

2010-08-01

After the invention of the cigarette 1881 the health consequences of active smoking were fully known only in 1964. Since 1986 research findings allow increasingly stronger conclusions about the impact of passive smoking on health, especially for lung cancer, cardiovascular and respiratory disease in adults and children and the sudden infant death syndrome. On the basis of current consumption patterns, approximately 450 million adults will be killed by smoking between 2000 and 2050. At least half of these adults will die between age 30 and 69. Cancer and total deaths due to smoking have fallen so far only in men in high-income countries but will rise globally unless current smokers stop smoking before or during middle age. Higher taxes, regulations on smoking, including 100 % smoke free indoor spaces, and information for consumers could avoid smoking-associated deaths. Irland was 2004 the first country worldwide introducing smoke free bars and restaurants with positive effects on compliance, health of employees and business. In the first year after the introduction these policies have resulted in a 10 - 20 % reduction of acute coronary events. In Switzerland smoke free regulations have been accepted by popular vote first in the canton of Ticino in 2006 and since then in 15 more cantons. The smoking rate dropped from 33 to 27 % since 2001.

Tobacco price increases and population interest in smoking cessation in Japan between 2004 and 2016: a Google Trends analysis.

Tobacco price increases can generate increased public interest in smoking cessation, but it is not clear how long this interest lasts. Our objective was to evaluate the duration of the impact of cigarette price increase in Japan using Google search data. Monthly or daily aggregated Google search volume for smoking cessation in Japan from 2004 to 2016 was collected in terms of relative search volume (RSV) ranging from 0-100. Using monthly RSV data, we evaluated possible relationships between the RSVs and tobacco control measures in Japan. Time periods within which the impact of search volume significantly increased were identified by cluster detection test, using daily RSV data. A spike in RSV preceding the enforcement of a cigarette price increase revealed an anticipation effect. Between 2004 and 2016 the three highest monthly RSV spikes were observed in July 2006 (RSV=66), when cigarette prices increased by 11%, and in September (RSV=90) and October 2010 (RSV=100), when cigarette prices increased by 37%. Regarding daily RSV, the detected cluster size around the price increase in 2010 (52 days) was longer than that in 2006 (17 days). In 2010, a cluster period of 25 days before the date of the price increase was observed, suggesting an anticipation effect. After the onset of the price increase, a cluster of 27 days was detected. When the cigarette price increased due to consumption tax in April 2014, almost no anticipation effect was observed. The population impact of tobacco price increases on smoking cessation may be assessed using Google Trends data. The cluster indicates that a higher cigarette price increase had a higher and longer-lasting effect on population interest in cessation, but the impact may continue for a relatively short time. To examine the duration of the impact of cigarette price increases on population interest in smoking cessation in Japan, Google search data for smoking cessation was analyzed. Between 2004 and 2016 the three highest spikes of

Gaudreau, Katherine; Sanford, Carolyn J.; Cheverie, Connie; McClure, Carol

2013-01-01

Background This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI) enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke) and respiratory (chronic obstructive pulmonary disease and asthma) conditions were examined before and after the smoking ban.

This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI) enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke) and respiratory (chronic obstructive pulmonary disease and asthma) conditions were examined before and after the smoking ban. Crude annual and monthly admission rates for the above conditions were calculated from April 1, 1995 to December 31, 2008 in all PEI acute care hospitals. Autoregressive Integrated Moving Average time series models were used to test for changes in mean and trend of monthly admission rates for study conditions, control conditions and a control province after the comprehensive smoking ban. Age- and sex-based analyses were completed. The mean rate of acute myocardial infarctions was reduced by 5.92 cases per 100,000 person-months (P = 0.04) immediately after the smoking ban.

The island country of Samoa (population 188,000 in 2011) forms part of Polynesia in the South Pacific. Over the past several decades Samoa has experienced exceptional modernization and globalization of many sectors of society, with noncommunicable diseases (NCD) now the leading cause of morbidity and mortality. The evolution of risk factor prevalence underpinning the increase in NCDs, however, has not been well described, including tobacco smoking which is related to cardiovascular disease, lung cancer, and chronic obstructive pulmonary disease. The present study examines tobacco smoking in relation to different forms and effects of globalization in Samoa using 7 population-based surveys (n = 9223) over 1978-2013. The prevalence of daily tobacco smoking steadily decreased over 1978-2013 from 76% to 36% in men, and from 27% to 15% in women (p < 0.0001 both sexes). During 1991-2013, current tobacco smoking also steadily decreased from 64% to 40% in men (p < 0.0001), and from 21% to 17% in women (p < 0.05). Declines were similar in younger (25-44 years) and older (45-64 years) men and women. Colonial globalization facilitated the introduction and prolific spread of tobacco trade and consumption in the Pacific Islands from the sixteenth century, with many populations inexorably pulled into trade relations and links to the global economy. It has also been a different globalization which may have led to the decline in smoking prevalence in Samoa in recent decades, through global dissemination since the 1950s of information on the harmful effects of tobacco smoking derived from research studies in the USA and Europe. Over the past 35 years tobacco smoking has steadily declined among Samoan adults; the only NCD risk factor to demonstrate marked declines during this period. By 2013 tobacco smoking in women had decreased to levels similar to Australia and New Zealand (ANZ), however in men smoking prevalence remained more than three times higher than ANZ. The

To investigate the longitudinal impact of smoking cessation and relapse on the exercise habits of apparently healthy Japanese men, 750 subjects presenting for a checkup at a metropolitan health center were surveyed annually for 7 years. Exercise was dichotomously classified as none or any. Subjects were grouped in two categories: 98 smokers who ceased smoking during the second year of the study, matched with 196 continuing smokers and 196 men who had never smoked; and 52 relapsed smokers (including 2 new smokers) who did not smoke at baseline or at Year 1 but smoked from Year 2 to final follow-up, matched with 104 continuing smokers and 104 never-smokers. Based on self-reported responses to questionnaires, exercise was consistently less prevalent among smokers who did not quit than among never-smokers throughout the study. Habitual exercise in subjects who had quit smoking increased during the follow-up (any exercise: 42.9% at baseline increased to 51% at final follow-up, p for longitudinal trend = .115). Habitual exercise in matched never-smokers did not change during the study and decreased significantly among persistent smokers (p = .025). Habitual exercise in relapsed smokers decreased during the follow-up (any exercise: 50.0% at baseline declined to 32.7% at final follow-up, p = .007), but habitual exercise in matched persistent smokers and never-smokers did not change. We conclude that smoking and sedentary lifestyle coexist continuously, that smoking cessation is associated with increased habitual exercise among healthy men, and that relapse is associated with reduced habitual exercise, suggesting that cigarette smoking weakens exercise habits.

Household and school-level influences on smoking behavior among Korean adolescents: a multilevel analysis.

Trends in adolescent smoking rates in South Korea have not shown substantial progress due to a lack of effective anti-smoking interventions and policies in school settings. We examined individual- and school-level determinants of adolescent smoking behavior (ever smoking, current smoking, and daily smoking) using the nationally representative fifth Korean Youth Risk Behavior Web-based Survey conducted in 2009. We found that students in coeducation schools or vocational high schools had greater risks of smoking for each type of smoking behavior than those in single-sex schools or general high schools, respectively even after controlling for individual-level factors. Higher family affluence and higher weekly allowances were associated with greater risks of ever smoking, current smoking and daily smoking even after controlling for parental education and other confounders. Whilst caution is required in interpreting results given the cross-sectional nature of the study, our findings suggest that in addition to raising the price of cigarettes, youth anti-smoking interventions in South Korea may benefit from focusing on coeducation schools and vocational high schools.

Smoke-free air laws have been implemented in many Kentucky communities to protect the public from the harmful effects of secondhand smoke exposure. The impact of different strengths of smoke-free air laws on indoor air quality was assessed. Indoor air quality in hospitality venues was assessed in seven communities before and after comprehensive smoke-free air laws and in two communities only after partial smoke-free air laws. One community was measured three times: before any smoke-free air law, after the initial partial law, and after the law was strengthened to cover all workplaces and public places with few exemptions. Real-time measurements of particulate matters with 2.5 mum aerodynamic diameter or smaller (PM(2.5)) were obtained. When comprehensive smoke-free air laws were implemented, indoor PM(2.5) concentrations decreased significantly from 161 to 20 microg/m3. In one community that implemented a comprehensive smoke-free law after initially passing a partial law, indoor PM(2.5) concentrations were 304 microg/m3 before the law, 338 microg/m3 after the partial law, and 9 microg/m3 after the comprehensive law. The study clearly demonstrated that partial smoke-free air laws do not improve indoor air quality. A significant linear trend indicated that PM(2.5) levels in the establishments decreased with fewer numbers of burning cigarettes. Only comprehensive smoke-free air laws are effective in reducing indoor air pollution from secondhand tobacco smoke.

T-cell receptor variable genes and genetic susceptibility to celiac disease: an association and linkage study.

Genetic susceptibility of celiac disease is primarily associated with a particular combination of and HLA-DQA1/DQB1 gene; however, this does not fully account for the genetic predisposition. Therefore, the aim of this study was to examine whether T-cell receptor (TCR) genes may be susceptibility genes in celiac disease. HLA class II typing was performed by polymerase chain reaction amplification in combination with sequence-specific oligonucleotide hybridization. TCR alpha (TCRA), TCR gamma (TCRG), and TCR beta (TCRB) loci were investigated by restriction fragment length polymorphism analysis. Allelic frequencies of TCRA, TCRG, and TCRB variable genes were compared between patients with celiac disease (n = 53) and control patients (n = 67), and relative risk (RR) estimates were calculated. The RR was 1.67 for allele C1 at TCRA1, 3.35 for allele D2 at TCRA2, 1.66 for allele B2 at TCRG, and 1.35 for allele B at TCRB, showing no significant association. Additionally, linkage analysis was performed in 23 families. The logarithm of odd scores for celiac disease vs. the TCR variable genes at TCRA, TCRG, and TCRB showed no significant linkage. These data suggest that the analyzed TCR variable gene segments V alpha 1.2, V gamma 11, and V beta 8 do not play a major role in susceptibility to celiac disease.

Objectives. We evaluated a Social Branding antitobacco intervention for “hipster” young adults that was implemented between 2008 and 2011 in San Diego, California. Methods. We conducted repeated cross-sectional surveys of random samples of young adults going to bars at baseline and over a 3-year follow-up. We used multinomial logistic regression to evaluate changes in daily smoking, nondaily smoking, and binge drinking, controlling for demographic characteristics, alcohol use, advertising receptivity, trend sensitivity, and tobacco-related attitudes. Results. During the intervention, current (past 30 day) smoking decreased from 57% (baseline) to 48% (at follow-up 3; P = .002), and daily smoking decreased from 22% to 15% (P < .001). There were significant interactions between hipster affiliation and alcohol use on smoking. Among hipster binge drinkers, the odds of daily smoking (odds ratio [OR] = 0.44; 95% confidence interval [CI] = 0.30, 0.63) and nondaily smoking (OR = 0.57; 95% CI = 0.42, 0.77) decreased significantly at follow-up 3. Binge drinking also decreased significantly at follow-up 3 (OR = 0.64; 95% CI = 0.53, 0.78). Conclusions. Social Branding campaigns are a promising strategy to decrease smoking in young adult bar patrons. PMID:24524502

Smoking prevalence: a comparison of two American surveys.

2009-09-01

To compare smoking prevalence estimates from two nationally representative surveys in the USA. Smoking prevalence estimates derived from the National Health Interview Survey (NHIS) and the National Survey on Drug Use and Health (NSDUH) for the period 1998-2005. Comparisons according to age (18-34 or 35+ years) and according to smoking frequency (every day or some days). In 1998, the prevalence of smoking in both surveys was nearly identical at 24%. From 1999 to 2005, a divergence occurred in smoking prevalence found by the NSDUH and the NHIS. By 2005, NHIS prevalence had declined to 20.9% [95% confidence interval (CI) 20.3-21.5], but the NSDUH estimate was 25.4% (95%CI 24.6-26.2), amounting to 9.1 million more smokers. In 1999, prevalence among 18-34 year olds in the NSDUH was only 18% (95%CI 13-22) higher than that in the NHIS, but that difference had doubled by 2005, when smoking prevalence among 18-34 year olds was 36% (95%CI 30-41) higher in the NSDUH than in the NHIS. NSDUH and NHIS prevalence among 35+ year olds were similar in 1999 and 2001, but the difference was 13% (95%CI 9-18) in 2005. Higher smoking prevalence estimates in the NSDUH were largely due to much higher estimates for some-day smoking in that survey, although every-day smoking prevalence among 18-34 year-olds was also higher in the NSDUH than in the NHIS. These results raise doubt about the recent decline in smoking prevalence described by the NHIS. Further investigation of the NSDUH/NHIS discrepancy may lead to better surveys and to a clearer picture of smoking trends in the USA.

Impacts of smoke-free public places legislation on inequalities in youth smoking uptake: study protocol for a secondary analysis of UK survey data

Introduction Smoke-free public places legislation has been introduced in many countries to protect the public from the harmful effects of secondhand smoking. While evaluations of smoke-free policies have demonstrated major public health benefits, the impact on youth smoking and inequalities in smoking remains unclear. This project aims to evaluate how smoke-free public places legislation in the UK has impacted on inequalities in youth smoking uptake, and how much of any impact is via changes in parental smoking behaviour. Methods and analysis The study will constitute secondary analyses of UK data (from the British Household Panel Survey and the Understanding Society study). Merging these datasets gives coverage of the period from 1994 to 2016. Missing data will be handled using multiple imputation. The primary outcomes are the rates and inequalities in initiation, experimentation, escalation to daily smoking and quitting among youths aged 11–15 years. Secondary outcomes include the prevalence of smoking among parents of these youths. Discrete-time event history analysis will be conducted to examine whether changes in the probability of youth smoking transitions are associated with the implementation of the smoke-free public places legislation; and whether any observed effects differ by socioeconomic position and parental smoking. A multilevel logistic regression model will be used to investigate whether there is a step change or change in trend for the prevalence of parental smoking after the policy was implemented. The models will be adjusted for relevant factors (including cigarette taxation, the change in the legal age for purchase of cigarettes and e-cigarette prevalence) that may be associated with the implementation of the legislation. Ethics and dissemination This project will use anonymised survey data which have been collected following independent ethical review. The dissemination of the study findings will adopt multiple communication channels

To compare prevalence estimates and assess issues related to the measurement of adult cigarette smoking in the National Health Interview Survey (NHIS) and the National Survey on Drug Use and Health (NSDUH). 2008 data on current cigarette smoking and current daily cigarette smoking among adults ≥18 years were compared. The standard NHIS current smoking definition, which screens for lifetime smoking ≥100 cigarettes, was used. For NSDUH, both the standard current smoking definition, which does not screen, and a modified definition applying the NHIS current smoking definition (i.e., with screen) were used. NSDUH consistently yielded higher current cigarette smoking estimates than NHIS and lower daily smoking estimates. However, with use of the modified NSDUH current smoking definition, a notable number of subpopulation estimates became comparable between surveys. Younger adults and racial/ethnic minorities were most impacted by the lifetime smoking screen, with Hispanics being the most sensitive to differences in smoking variable definitions among all subgroups. Differences in current cigarette smoking definitions appear to have a greater impact on smoking estimates in some sub-populations than others. Survey mode differences may also limit intersurvey comparisons and trend analyses. Investigators are cautioned to use data most appropriate for their specific research questions.

OBJECTIVE Exposure to secondhand smoke (SHS) from cigarettes poses a significant health risk to nonsmokers. Among youth, the home is the primary source of SHS. However, little is known about youth exposure to SHS in other nonpublic areas, particularly motor vehicles. METHODS Data were obtained from the 2000, 2002, 2004, 2006, and 2009 waves of the National Youth Tobacco Survey, a nationally representative survey of US students in grades 6 to 12. Trends in SHS exposure in a car were assessed across survey years by school level, gender, and race/ethnicity by using binary logistic regression. RESULTS From 2000 to 2009, the prevalence of SHS exposure in cars declined significantly among both nonsmokers (39.0%–22.8%; trend P < .001) and smokers (82.3%–75.3%; trend P < .001). Among nonsmokers, this decline occurred across all school level, gender, and race/ethnicity subgroups. CONCLUSIONS SHS exposure in cars decreased significantly among US middle and high school students from 2000 to 2009. Nevertheless, in 2009, over one-fifth of nonsmoking students were exposed to SHS in cars. Jurisdictions should expand comprehensive smoke-free policies that prohibit smoking in worksites and public places to also prohibit smoking in motor vehicles occupied by youth. PMID:22311992

Functional CYP2A6 genetic variation partially determines nicotine metabolism. In 2005, we examined functional CYP2A6 variants associated with reduced metabolism (CYP2A6*2, CYP2A6*9, CYP2A6*4), smoking history, and change in smoking in 878 adult smokers undergoing lung cancer screening in an urban setting. At one year, 216 quit smoking for more than 30 days while 662 continued smoking. Compared to subjects who smoked 30 cigarettes per day at baseline, the odds of a reduced metabolism genotype was 52% higher in subjects smoking 20-29 cigarettes per day and 86% higher in subjects smoking less than 20 cigarettes per day (p-trend = 0.016). Reduced metabolism genotypes appeared unrelated to quitting. Though related to smoking dose, CYP2A6 may not influence cessation.

Comprehensive smoke-free laws--50 largest U.S. cities, 2000 and 2012.

PubMed

2012-11-16

Secondhand smoke (SHS) exposure causes heart disease and lung cancer in nonsmoking adults and several health conditions in children. Only completely eliminating smoking in indoor spaces fully protects nonsmokers from SHS. State and local laws can provide this protection in enclosed workplaces and public places by completely eliminating smoking in these settings. CDC considers a smoke-free law to be comprehensive if it prohibits smoking in all indoor areas of private workplaces, restaurants, and bars, with no exceptions. In response to growing evidence on the health effects of SHS, communities and states have increasingly adopted comprehensive smoke-free (CSF) laws in recent years. To assess trends in protecting the population from SHS exposure, CDC and the American Nonsmokers' Rights Foundation (ANRF) compared coverage by local or state CSF laws in the 50 largest U.S. cities as of December 31, 2000, and October 5, 2012. The analysis focused on smoking restrictions in the 50 largest cities because these cities represent an important indicator of nationwide trends in local and state policy and because they are home to an estimated 47 million persons, or nearly 15% of the U.S. population. The analysis found that the number of these cities covered by local and/or state CSF laws increased from one city (2%) in 2000 to 30 cities (60%) in 2012. A total of 20 cities (40%) were not covered by a CSF law at either the local or state level in 2012, although 14 of these cities had 100% smoke-free provisions in place at the local or state level in at least one of the three settings considered. The results of this analysis indicate that substantial progress has been achieved during 2000-2012 in implementing CSF laws in the 50 largest U.S. cities. However, gaps in coverage, especially in the southern United States and in states with laws that preempt local smoking restrictions, are contributing to disparities in SHS protections.

The Contribution of Smoking to Educational Gradients in U.S. Life Expectancy*

Ho, Jessica Y.; Fenelon, Andrew

2014-01-01

Researchers have documented widening educational gradients in mortality in the United States since the 1970s. While smoking has been proposed as a key explanation for this trend, no prior study has quantified the contribution of smoking to increasing education gaps in longevity. We estimate the contribution of smoking to educational gradients in life expectancy using data on white men and women aged 50 and above from the National Longitudinal Mortality Study (N=283,430; 68,644 deaths) and the National Health Interview Survey (N=584,811; 127,226 deaths) in five periods covering the 1980s to 2006. In each period, smoking makes an important contribution to education gaps in longevity for white men and women. Smoking accounts for half the increase in the gap for white women but does not explain the widening gap for white men in the most recent period. Addressing greater initiation and continued smoking among the less educated may reduce mortality inequalities. PMID:26199287

Changes in hospitalization rates for acute coronary syndrome after a two-phase comprehensive smoking ban.

The impact of a comprehensive stepwise smoking ban (2007 and 2008) was assessed by analysing the hospitalization rate for acute coronary syndrome (ACS) in France, between 2003 and 2009. Between 2003 and 2009, 867,164 hospitalizations for ACS were observed among about 23 million administrative reports. The age-and gender-standardized hospitalization rates were calculated and their variation before and after the smoking ban implementation was investigated by Poisson regression that included the ACS seasonal variations and the historical trend. The hospitalization rate decreased by 12.8% (from 269 to 235/100,000) with a significant historical trend reduction (p < 0.10(-3)) in all groups, but in young women. After adjusting for linear trend, reductions linked to the ban remained not significant in all groups: relative risk (RR) from 0.96 (95% CI 0.91-1.01) in men older than 55 years to 0.99 (95% CI 0.93-1.04) in men aged 55 years or less after the first phase, and from 0.96 (95% CI 0.89-1.04) in men older than 55 years to 1.03 (95% CI 0.94-1.12) in women older than 65 years after the second phase of the ban. This study did not demonstrate a significant effect of a two-phases smoking ban on ACS hospitalization rate. A steadily decrease of this rate over the 7-year period, the past preventive measures in France leading to low levels of passive smoking, and the significant increase in active smoking during the studied period may explain this result. Our study highlights the difficulty of proving an effect of smoking bans in a country with an already low ACS incidence. © The European Society of Cardiology 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The smoking prevalence rate among adult women and pregnant women has decreased only 0.3 to 0.5% per year since 1969. Without a nationwide dissemination of efficacious smoking cessation methods based on these trends, by the year 2000 the smoking prevalence among pregnant women will be approximately 18%. This estimate is well above the US Department of Health and Human Services Year 2000 Objective of 10%. The US dissemination of tested smoking cessation methods could help an additional 12,900 to 155,000 pregnant smokers annually and 600,000 to 1,481,000 cumulatively to quit smoking during the 1990s. Dissemination could help achieve 31 to 78% of the Year 2000 Objectives for pregnancy smoking prevalence. (With dissemination, at best a 15% smoking prevalence during pregnancy, rather than the 10% objective, is likely to be observed.) Our results confirm a well-documented need for a national campaign to disseminate smoking cessation methods. PMID:8427318

The role of tobacco control policies in reducing smoking and deaths in a middle income nation: results from the Thailand SimSmoke simulation model.

With the male smoking prevalence near 60% in 1991, Thailand was one of the first Asian nations to implement strict tobacco control policies. However, the success of their efforts has not been well documented. The role of tobacco control policies are examined using the "SimSmoke" tobacco control model. We first validated the model against survey data on smoking prevalence. We then distinguished the effect of policies implemented between 1991 and 2006 from long-term trends in smoking rates. We also estimated smoking attributable deaths and lives saved as a result of the policies. The model validates well against survey data. The model shows that by the year 2006, policies implemented between 1991 and 2006 had already decreased smoking prevalence by 25% compared to what it would have been in the absence of the policies. Tax increases on cigarettes and advertising bans had the largest impact, followed by media anti-smoking campaigns, clean air laws and health warnings. The model estimates that the policies saved 31 867 lives by 2006 and will have saved 319,456 lives by 2026. The results document the success of Thailand in reducing smoking prevalence and reducing the number of lives lost to smoking, thereby showing the potential of tobacco control policies specifically in a middle-income country. Additional improvements can be realised through higher taxes, stronger clean air policies, comprehensive cessation treatment policies, and targeted media campaigns.

Smoking bans were suggested to reduce smoking prevalence and increase quit ratio but their equity impact remains unclear. We aimed to characterise the socioeconomic status (SES)-related inequalities in smoking prevalence and quit ratio before and after the implementation of a public smoking ban. We included data from 17 544 participants in the population-based cross-sectional Bus Santé study in Geneva, Switzerland, between 1995 and 2014. We considered educational attainment (primary, secondary and tertiary) as a SES indicator. Outcomes were smoking prevalence (proportion of current smokers) and quit ratio (ex-smokers to ever-smokers ratio). We used segmented linear regression to assess the overall impact of smoking ban on outcome trends. We calculated the relative (RII) and slope (SII, absolute difference) indexes of inequality, quantifying disparities between educational groups in outcomes overall (1995-2014), before and after ban implementation (November 2009). Least educated participants displayed higher smoking prevalence (RII=2.04, P<0.001; SII=0.15, P<0.001) and lower quit ratio (RII=0.73, P<0.001; SII=-0.18, P<0.001). As in other studies, smoking ban implementation coincided with a temporary reduction of smoking prevalence (P=0.003) and increase in quit ratio (P=0.02), with a progressive return to preban levels. Inequalities increased (P<0.05) in relative terms for smoking prevalence (RII before =1.84, P<0.001 and RII after =3.01, P<0.001) and absolute terms for both outcomes (smoking prevalence: SII before =0.14, P<0.001 and SII after =0.19, P<0.001; quit ratio: SII before =-0.15, P<0.001 and SII after =-0.27, P<0.001). Implementation of a public smoking ban coincided with a short-lived decrease in smoking prevalence and increase in quit ratio but also with a widening in SES inequalities in smoking-related outcomes. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

To investigate the associations of parental smoking and secondhand smoke (SHS) exposure at home with smoking initiation among young children in Hong Kong. A prospective school-based survey of Hong Kong primary 2-4 students was conducted at baseline in 2006 and followed up in 2008. Self-administered anonymous questionnaires were used to collect information about smoking, SHS exposure at home, parental smoking, and sociodemographic characteristics. Cross-sectional and prospective associations of SHS exposure at home and parental smoking with student smoking were analyzed using logistic regression adjusting for potential confounders. Cross-sectional association between parental smoking and ever smoking was significant with adjustment of sociodemographic characteristics but became insignificant after adjusting for home SHS exposure. Home SHS exposure mediated the association between parental smoking and students smoking (p = .03). Prospectively, parental smoking was not associated with smoking initiation after adjusting for home SHS exposure. Each day increase in home SHS exposure significantly predicted 16% excess risk of smoking initiation after adjusting for parental smoking. The prospective effect of parental smoking on smoking initiation was significantly mediated by baseline home SHS exposure (p < .01). Higher exposure to SHS at home predicted smoking initiation of young Chinese children in Hong Kong independent of parental smoking status. On the other hand, the effect of parental smoking on smoking initiation was mediated through SHS exposure at home. To prevent children from smoking as well as the harm of SHS exposure, parents and other family members should quit smoking or at least reduce smoking at home.

There is substantial empirical evidence that negative mood triggers smoking behavior, and less support for the similar effect of positive mood. However, the relationship between the intensity of mood and smoking remains relatively under-researched. The present study explored the association between mood intensity and smoking behavior. Seventy-three ad libitum smokers recorded their mood and concurrent number of smoked cigarettes three times daily for one week using electronic diary application. Real time assessment in natural environment enabled greater reliability, validity and generalizability of the collected data. We analyzed results using within-subjects approach and obtained significant growth trend in smoking behavior that concurred with the increase of mood intensity-smokers tended to increase their consumption of cigarettes when they were feeling either happy or sad in comparison to the situation when they were in neutral mood. These findings raise implications regarding the role of mood intensity in initiating smoking behavior.

Hahn, Ellen J.; Robertson, Heather E.; Vogel, Suzann L.; Travers, Mark J.

2009-01-01

Introduction: Smoke-free air laws have been implemented in many Kentucky communities to protect the public from the harmful effects of secondhand smoke exposure. The impact of different strengths of smoke-free air laws on indoor air quality was assessed. Methods: Indoor air quality in hospitality venues was assessed in seven communities before and after comprehensive smoke-free air laws and in two communities only after partial smoke-free air laws. One community was measured three times: before any smoke-free air law, after the initial partial law, and after the law was strengthened to cover all workplaces and public places with few exemptions. Real-time measurements of particulate matters with 2.5 μm aerodynamic diameter or smaller (PM2.5) were obtained. Results: When comprehensive smoke-free air laws were implemented, indoor PM2.5 concentrations decreased significantly from 161 to 20 μg/m3. In one community that implemented a comprehensive smoke-free law after initially passing a partial law, indoor PM2.5 concentrations were 304 μg/m3 before the law, 338 μg/m3 after the partial law, and 9 μg/m3 after the comprehensive law. Discussion: The study clearly demonstrated that partial smoke-free air laws do not improve indoor air quality. A significant linear trend indicated that PM2.5 levels in the establishments decreased with fewer numbers of burning cigarettes. Only comprehensive smoke-free air laws are effective in reducing indoor air pollution from secondhand tobacco smoke. PMID:19346510

To study the impact of implementing smoke-free workplace and hospitality industry legislation on smoking behaviour. A cross-sectional population survey from 2001 to 2008 (n ≈ 18,000 per year) was used to assess trends and seasonal patterns in smoking and quitting, and to examine whether changes could be observed after the workplace smoking ban in the Netherlands in 2004 and the hospitality industry ban in 2008. Outcome measures were smoking prevalence, quit attempts and successful quit attempts. Interactions with educational level (socio-economic status) and bar visiting (exposure to the hospitality industry ban) were tested. The workplace ban was followed by a decrease in smoking prevalence (OR = 0.91, P < 0.001), but the hospitality industry ban was not (OR = 0.96, P = 0.127). Both bans, especially the workplace ban, were followed by an increase in quit attempts and successful quit attempts: workplace ban, OR = 1.31, P < 0.001; OR = 1.49, P < 0.001; hospitality industry ban, OR = 1.13, P = 0.013; OR = 1.44, P < 0.001. The workplace ban had a larger effect on successful quitting among higher-educated (OR = 0.35, P < 0.001) than on lower-educated respondents (OR = 0.74, P = 0.052). The hospitality industry ban had a larger effect on quit attempts among frequent bar visitors (OR = 1.48, P = 0.003) than on non-bar visitors (OR = 0.71, P = 0.014). A workplace smoking ban in the Netherlands was followed by more changes in smoking and quitting than a hospitality industry ban. The hospitality industry ban only appeared to have an impact on quit attempts, and not on smoking prevalence. © 2010 The Authors, Addiction © 2010 Society for the Study of Addiction.

Objectives To analyse the trends and trend changes in myocardial infraction (MI) and coronary heart disease (CHD) admissions, to investigate the effects of the 2007 smoke-free legislation on these trends, and to consider the policy implications of any findings. Design setting Liverpool (city), UK. Participants Hospital episode statistics data on all 56 995 admissions for CHD in Liverpool between 2004 and 2012 (International Classification of Diseases codes I20–I25 coded as an admission diagnosis within the defined dates). Primary and secondary outcome measures Trend gradient and change points (by trend regressions analysis) in age-standardised MI admissions in Liverpool between 2004 and 2012; by sex and by socioeconomic status. Secondary analysis on CHD admissions. Results A significant and sustained reduction was seen in MI admissions in Liverpool beginning within 1 year of the smoking ban. Comparing 2005/2006 and 2010/2011, the age-adjusted rates for MI admissions fell by 42% (39–45%) (41.6% in men and by 42.6% in women). Trend analysis shows that this is significantly greater than the background trend of decreasing admissions. These reductions appeared consistent across all socioeconomic groups. Interestingly, admission rates for total CHD (including mild to severe angina) increased by 10% (8–12%). Conclusions A dramatic reduction in MI admissions in Liverpool has been observed coinciding with the smoking ban in 2007. Furthermore, the benefits were apparent across the socioeconomic spectrum. Health inequalities were not affected and may even have been reduced. The rapid effects observed with this top-down, environmental policy may further increase its value to policymakers.

Parental smoking and children's attention to smoking cues.

PubMed

Lochbuehler, Kirsten; Otten, Roy; Voogd, Hubert; Engels, Rutger C M E

2012-07-01

Research has shown that children with smoking parents are more likely to initiate smoking than children with non-smoking parents. So far, these effects have been explained through genetic factors, modelling and norm-setting processes. However, it is also possible that parental smoking affects smoking initiation through automatic cognitive processes. Therefore, we examined whether children with a smoking parent focus longer, faster and more often on smoking cues. The children were given two movie clips to watch, during which their attention to smoking cues was assessed with eye-tracking technology. Results showed that children with a smoking parent focused more often and longer on smoking cues compared with children with non-smoking parents. No correlations between attentional bias and explicit smoking cognitions were found. In conclusion, results suggest that parental smoking affects children's attention to smoking cues. These findings may indicate that parental smoking instigates automatic cognitive processes in children who have not experimented with smoking, and possibly even before explicit smoking cognitions become more favourable.

Smoking has declined in Canada in recent years. However, it is not clear whether differences in current smoking by socioeconomic status have increased, decreased, or remained unchanged in Canada. We examined rates of current smoking by sex, education, and province from 1950 to 2011. Differences in current smoking, initiation, and cessation were summarized using relative and absolute measures. Between 1950 and 2011, the prevalence of current smoking (including daily and non-daily) among adults aged 20 years and older decreased steadily in men from 68.9 % (95 % CI 63.9-73.3) to 18.6 % (14.9-22.1) but in women increased slightly from 38.2 % (32.3-42.2) in 1950 to 39.1 % (36.4-41.2) in 1959 before declining to 15.4 % (11.9-18.9) in 2011. Among men, there was an inverse association between educational attainment and smoking which was consistent from 1950 to 2011. A similar gradient emerged in the mid-1960s in women. Absolute differences in rates of smoking across levels of education increased despite overall declines in smoking across all levels of education. Rates of smoking in women and men were higher in the Atlantic Provinces and Quebec, although in men these differences have declined since the 1990s. In a subset of data from 1999 to 2011, those with lower levels of education had higher levels of smoking initiation and lower levels of cessation. Smoking rates have fallen over time but socioeconomic differences have increased. Smoking prevalence peaked later in lower socioeconomic status (SES) groups, and rates of decline in lower SES groups and certain provinces have been less steep. This suggests that SES gradients emerge rapidly in later stages of the tobacco epidemic and may have increased through greater efficacy of tobacco control policies in reducing smoking among those of higher SES compared to those of lower SES. Tailored approaches may be required to reduce smoking rates in those of lower SES and narrow SES differences.

This study examined changes in adult daily smoking in 1981-2005 in Finland, in order to evaluate the impact of the 1995 Tobacco Control Act Amendment (TCAA) and accompanying measures on the proportion of daily smokers. The main focus of the TCAA was to prohibit smoking at workplaces (designated rooms excluded) in order to protect workers from environmental tobacco smoke. The study was based on data from annual postal surveys among 15- to 64-year-olds in 1981-2005 (average response rate 73%). The data set for this study comprised men and women aged 25-64 years (n = 73 471). Logistic models were used to test the effect of the 1995 TCAA across employment status while controlling for the effect of changes in the real price of tobacco and in gross domestic product per capita, and adjusting for age, education, secular trend and prevalence of ever-smokers in each birth cohort. Controlling for confounding factors, the odds ratio (OR) for daily smoking after 1995 among employed men was 0.83 (95% CI 0.73-0.94) compared with the OR (1.0) for the period ending 1994. The corresponding figure for employed women was 0.78 (95% CI 0.68-0.91). The results can be interpreted as a positive effect of the 1995 TCAA on employees' daily smoking. Moreover, a similar decrease in daily smoking was not seen among those not targeted by the TCAA (including farmers, students, housewives, pensioners and the unemployed). Smoking behaviour was and can be influenced by national tobacco policy measures.

This study aimed to describe the recent trends in youth smoking behaviors, and examine cigar and smokeless tobacco use patterns among youth smokers in New York City. Data, analyzed in 2014, were from the New York City Youth Risk Behavior Survey, a cross-sectional survey conducted bi-annually since 1997 in a representative sample of New York City public high school students (2001-2013), n = 59,122. Cigarette smoking declined 53%, from 17.6% in 2001 to 8.2% in 2013 (p < 0.001). The proportion of cigar use among smokers doubled, from 22.2% in 2001 to 45.9% in 2013 (p < 0.001), while the proportion of smokeless tobacco use among smokers increased by 400% between 2001 and 2013 (4.2% vs. 21.2%, p < 0.001). Youth cigarette smoking rates in New York City decreased, while cigar smoking and smokeless tobacco use among smokers increased considerably. These data highlight trends in youth smoking behaviors within the context of New York City's comprehensive tobacco control program and stress the need for additional activity to spur further declines in cigarette smoking and reverse the trends in cigar and smokeless tobacco use among New York City youth. Results demonstrate the need for continuous surveillance and action by the public health community to counteract tobacco industry promotion of other products.

Preventing or reducing smoking-related complications in otologic and neurotologic surgery.

Golub, Justin S; Samy, Ravi N

To discuss effects of smoking on otologic surgery in an era of electronic (e-) cigarettes and proposals for legalization of marijuana. Physiologic mechanisms and clinical outcomes are presented. Tobacco smoke can cause a variety of tissue effects that may adversely impact otologic surgery outcomes. Results in tympanoplasty using temporalis fascia are inferior in smokers compared with nonsmokers. More recent data show that in cartilage tympanoplasty, graft incorporation rates in smokers may approach those of nonsmokers. However, these results may not be as durable long-term in smokers. Evidence from nonotologic studies suggests that smoking cessation and nicotine replacement therapy may reduce perioperative morbidity. No data are available on electronic cigarettes and otologic outcomes; however, based on the pathophysiologic mechanisms of tobacco smoking, electronic cigarettes are likely a safer alternative. Marijuana smoke also needs to be considered as more states consider legalization. Cigarette smoking negatively influences otologic surgery results, mostly because of tobacco combustion byproducts. Counseling and, if needed, pharmacologic measures to reduce smoking are recommended. E-cigarettes that deliver nicotine in water vapor may be safer than tobacco smoking. Our review contributes to the discussion of how the trends of e-cigarette use and marijuana legalization will unfold in the future to affect our patients' outcomes.

Cigarette smokers' intention to quit smoking in Dire Dawa town Ethiopia: an assessment using the Transtheoretical Model

PubMed Central

2010-01-01

Background Cessation of smoking reduces morbidity and mortality related to tobacco smoking. It is essential to explore the intention of individuals to quit smoking to design effective interventions. The objective of this study was to assess cigarette smokers' intention to quit smoking in Dire Dawa town using the Transtheoretical model. Methods From February 15 to 19, 2009, we conducted a community based cross-sectional study among 384 current cigarette smokers in Dire Dawa town east Ethiopia. Data was collected by trained personnel using a pretested structured questionnaire. The data was analyzed using SPSS version 16.0. Results Two hundred and nineteen (57%) smokers in the study area had the intention to quit cigarette smoking within the next six months and all the process of change had an increasing trend across the stages. Based on the Fragestrom test of nicotine dependence of cigarette, 35 (9.1%), 69 (18%) and 48(12.5%) were very high, high and medium dependent on nicotine respectively. For the majority 247(64.3%) of the respondents, the mean score of cons of smoking outweighs the pros score (negative decisional balance). Only 66(17.2%) had high self efficacy not to smoke in places and situations that can aggravate smoking. Conclusions Majority of the smokers had the intention to quit smoking. All the process of change had an increasing trend across the stages. Those who had no intention to quit smoking had high level of dependence on nicotine and low self efficacy. The pros of smoking were decreasing while the cons were increasing across the stages. Stage based interventions should be done to move the smokers from their current stage to an advanced stages of quitting cigarette smoking. PMID:20529337

Just Blowing Smoke? Social Desirability and Reporting of Intentions to Quit Smoking

PubMed Central

2013-01-01

Introduction: Do cigarette smokers really want to quit smoking or do they simply say they do in order to placate others and avoid criticism? In surveys of smokers, stated quit intentions and reports of quit attempts may be biased by social desirability concerns. This makes it difficult to interpret large-scale state and national surveys of smoking behavior that collect data through telephone and face-to-face interviews, methods that tend to evoke high levels of socially desirable responding. Methods: The 2007 Health Information National Trends Survey used a dual-frame design to query smokers’ quit intentions and past quit attempts in 1 of 2 ways: A self-administered mail survey (low pressure for socially desirable responding; n = 563), or an interviewer-administered telephone survey (high pressure for socially desirable responding; n = 499). Estimates derived from the 2 formats were compared to test for social desirability effects. Results: In both survey modes, approximately two thirds of smokers reported seriously considering quitting in the next 6 months (mail: 64.9%; telephone: 68.9%), and approximately half reported making a quit attempt in the past year (mail: 54.9%; telephone: 52.3%). Neither difference approached significance in logistic regressions controlling for demographics (ps > .24). Conclusions: It appears that a large proportion of smokers in the United States aspire to live smoke-free lives and are not simply responding in a socially desirable manner to deflect criticism in an antismoking social climate. Future research should (1) replicate this study with greater statistical power, (2) examine the possible effects of survey context (e.g., health survey vs. smoking pleasure survey), and (3) explore survey mode effects in specific subpopulations.

Whether smoking-induced lung inflammation subsides after smoking cessation is currently a matter of debate. We used computed tomography (CT) to evaluate the effect of smoking cessation on lung density in patients with COPD. Thirty-six patients quit smoking out of 254 current smokers with COPD who were followed with annual CT and lung function tests (LFT) for 2?4 years as part of a randomised placebo-controlled trial of the effect of inhaled budesonide on CT-lung density. Lung density was expressed as the 15th percentile density (PD15) and relative area of emphysema below -910 HU (RA-910). From the time-trends in the budesonide and placebo groups the expected CT-lung densities at the first visit after smoking cessation were calculated by linear regression and compared to the observed densities. Following smoking cessation RA-910 increased by 2.6% (p = 0.003) and PD15 decreased by -4.9 HU (p = 0.0002). Furthermore, changes were larger in the budesonide group than the placebo group (PD15: -7.1 vs -2.8 HU. RA-910 3.7% vs 1.7%). These differences were, however, not statistically significant. The LFT parameters (FEV(1) and diffusion capacity) were not significantly influenced by smoking cessation. Inflammation partly masks the presence of emphysema on CT and smoking cessation results in a paradoxical fall in lung density, which resembles rapid progression of emphysema. This fall in density is probably due to an anti-inflammatory effect of smoking cessation.

2015-09-01

In 2011, New York City (NYC) parks and beaches became smoke-free. There is currently little research evaluating the impact of such laws on smoking behaviour at the population level. We used an interrupted time-series study design to analyse data from the New York State Adult Tobacco Survey to assess the law's impact using the rest of New York State as a comparison. Trends in how frequently respondents noticed people smoking in parks and beaches were analysed between the third quarter of 2009 and the fourth quarter of 2012, comparing NYC to the rest of the state. The trend in the frequency of NYC residents noticing people smoking in local parks and beaches decreased significantly over the six quarters after the law took effect. There was no comparable decline among residents in the rest of the state. An increase in the number of respondents who never noticed people smoking in NYC contributed to this decline. These results are consistent with previous studies and provide population-level evidence that suggest the law has reduced smoking in parks and on beaches.

“How Is Smoking Handled in Your Home?”: Agreement Between Parental Reports on Home Smoking Bans in the United States, 1995–2007

PubMed Central

Zhang, Xiao; Kuo, Daphne; Jones, Nathan R.

2012-01-01

Introduction: Home smoking bans significantly reduce secondhand smoke exposure among children, but parents may offer discordant reports on whether there is a home smoking ban. The purpose of this study was to examine national trends in (a) parental discordance/concordance in the reporting of home smoking bans and (b) correlates of discordant/concordant reports among two-parent households with underage children from 1995 to 2007. Methods: Data from the 1995/1996, 1998/1999, 2001/2002, 2003, and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey were used to estimate prevalence rates and multinomial logistic regression models of discordant/concordant parental smoking ban reports by survey period. Results: Overall, the percentage of households in which the 2 parents gave discordant reports on a complete home smoking ban decreased significantly from 12.7% to 2.8% from 1995 to 2007 (p < .001). Compared with households where both parents reported a complete smoking ban, discordant reports were more likely to be obtained from households with current smokers (p < .01) across survey periods. Compared with households where both parents reported the lack of a complete home smoking ban, discordant reports were more likely among households with college graduates, no current smokers, and parents with Hispanic ethnicity (p < .05). Conclusions: Parental concordance on the existence of a home smoking ban increased from 1995 to 2007. This suggests estimates of home smoking bans based on just one parent may be more reliable now than they were in the past. Interventions to improve the adoption and enforcement of home smoking bans should target households with current smoker parents. PMID:22377935

Exposure to second-hand smoke is a threat to children's health. We developed a school-based smoke-free intervention (SFI) to support families in implementing smoke-free homes in Bangladesh, and gathered preliminary evidence of its effectiveness. A feasibility cluster randomized controlled trial of SFI was conducted in 24 schools in Mirpur, an urban area within Dhaka. Using simple stratified randomization, schools were allocated to: Arm A (SFI only), Arm B (SFI plus reminders), and Arm C (the control group). A total of 781 year-5 children (10-12 years old) in the consenting schools, participated in the study. Outcomes including "smoke-free homes" and "social visibility" that is, not smoking in front of children at home were assessed through questionnaire-based children's surveys, administered by researchers, at baseline and at weeks 1, 12, 27, and 52 in all arms. "Smoke-free homes" were significantly higher in Arm A (odds ratio [OR] = 4.8; 95% CI = 2.6-9.0) and in Arm B (OR = 3.9; 95% CI = 2.0-7.5) than in Arm C, when controlled for the baseline levels, at year 1. Similarly, "social visibility" was significantly reduced in Arm A (OR = 5.8; 95% CI = 2.8-11.7) and in Arm B (OR = 7.2; 95% CI = 3.3-15.9) than Arm C, when controlled for the baseline levels, at year 1. We observed an increasing trend (Cochrane Armitage test statistic [Z] = 3.8; p < .0001) in homes becoming smoke-free with increasing intensity of the intervention (control < Arm A < Arm B), and a decreasing trend (Z = -5.13; p < .0001) in social visibility at homes. SFI has the potential to encourage children to negotiate a smoke-free environment in their homes. © The Author 2015.

This study examined tobacco smoke pollution (also known as thirdhand smoke, THS) in hotels with and without complete smoking bans and investigated whether non-smoking guests staying overnight in these hotels were exposed to tobacco smoke pollutants. A stratified random sample of hotels with (n=10) and without (n=30) complete smoking bans was examined. Surfaces and air were analysed for tobacco smoke pollutants (ie, nicotine and 3-ethynylpyridine, 3EP). Non-smoking confederates who stayed overnight in guestrooms provided urine and finger wipe samples to determine exposure to nicotine and the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone as measured by their metabolites cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), respectively. Compared with hotels with complete smoking bans, surface nicotine and air 3EP were elevated in non-smoking and smoking rooms of hotels that allowed smoking. Air nicotine levels in smoking rooms were significantly higher than those in non-smoking rooms of hotels with and without complete smoking bans. Hallway surfaces outside of smoking rooms also showed higher levels of nicotine than those outside of non-smoking rooms. Non-smoking confederates staying in hotels without complete smoking bans showed higher levels of finger nicotine and urine cotinine than those staying in hotels with complete smoking bans. Confederates showed significant elevations in urinary NNAL after staying in the 10 most polluted rooms. Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens. Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective.

Waterpipe tobacco smoking (WTS) is an emerging tobacco product globally, especially among adolescents and young adults who may perceive WTS as a safe alternative to smoking cigarettes. Monitoring the use of WTS in Turkey in relation to the tobacco control policy context is important to ensure that WTS does not become a major public health issue in Turkey. The Global Adult Tobacco Survey (GATS) was conducted in Turkey in 2008 and was repeated in 2012. GATS provided prevalence estimates on current WTS and change over time. Other indicators of WTS were also obtained, such as age of initiation and location of use. Among persons aged 15 and older in Turkey, the current prevalence of WTS decreased from 2.3% in 2008 to 0.8% in 2012, representing a 65% relative decline. Among males, WTS decreased from 4.0% to 1.1% (72% relative decline). While the overall smoking prevalence decreased among females, there was no change in the rate of WTS (0.7% in 2008 vs. 0.5% in 2012), though the WTS prevalence rate was already low in 2008. Comprehensive tobacco control efforts have been successful in reducing the overall smoking prevalence in Turkey, which includes the reduction of cigarette smoking and WTS. However, it is important to continue monitoring the use of waterpipes in Turkey and targeting tobacco control efforts to certain groups that may be vulnerable to future WTS marketing (e.g., youth, women).

Country of Mexico. To determine mortality trends due to chronic obstructive pulmonary disease (COPD) in Mexico between 1999 and 2014. COPD mortality data for persons aged ≥40 years from 1999 to 2014 were obtained from the official website of the Mexican Ministry of Health. Age-standardised mortality rates (ASMRs) were calculated, and joinpoint regression analysis was used to identify trends over time. The annual per cent change (APC) was determined for each trend. A total of 313,962 COPD deaths (crude rate 66.3 per 100,000 population) was reported. Between 1999 and 2014, overall ASMRs decreased from 75.5 to 62.2/100,000 (APC -0.6, P = 0.03): from 94 to 74.7 (APC -0.8, P = 0.004) in males and from 59.7 to 51.8 (APC -0.2, P = 0.4) in females. COPD mortality rates in Mexico are slowly declining overall and among males. The reduction in smoking prevalence over time, and the new cigarette taxes and smoking laws implemented during the study period, have had no immediate impact on mortality. The lack of a decline in COPD mortality among females needs to be further investigated, particularly in rural areas, where the prevalence of biomass smoke exposure remains high.

We examined whether identifying with a film character who smokes increases implicit associations of the self with smoking. Undergraduate men were randomly assigned to view film clips in which the male protagonist either smoked or did not smoke. We measured subsequent levels of self-smoking associations using a reaction time task, as well as self-reported beliefs about smoking and smokers. Greater identification with the smoking protagonist predicted stronger implicit associations between the self and smoking (for both smokers and nonsmokers) and increased intention to smoke (among the smokers). Stronger implicit self-smoking associations uniquely predicted increases in smokers' intentions to smoke, over and above the effects of explicit beliefs about smoking. The results provide evidence that exposure to smoking in movies is causally related to changes in smoking-related thoughts, that identification with protagonists is an important feature of narrative influence, and that implicit measures may be useful in predicting deliberative behavior.

Grilled, barbecued, and smoked meat intake, a prevalent dietary source of polycyclic aromatic hydrocarbon (PAH) carcinogens, may increase the risk of incident breast cancer. However, no studies have examined whether intake of this PAH source influences survival after breast cancer. We interviewed a population-based cohort of 1508 women diagnosed with first primary invasive or in situ breast cancer in 1996 and 1997 at baseline and again approximately five years later to assess grilled/barbecued and smoked meat intake. After a median of 17.6 years of follow-up, 597 deaths, of which 237 were breast cancer related, were identified. Multivariable Cox regression was used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality as related to prediagnosis intake, comparing high (above the median) to low intake, as well as postdiagnosis changes in intake, comparing every combination of pre-/postdiagnosis intake to low pre-/postdiagnosis intake. All statistical tests were two-sided. High prediagnosis grilled/barbecued and smoked meat intake was associated with increased risk of all-cause mortality (HR = 1.23, 95% CI = 1.03 to 1.46). Other associations were noted, but estimates were not statistically significant. These include high prediagnosis smoked beef/lamb/pork intake and increased all-cause (HR = 1.17, 95% CI = 0.99 to 1.38, P trend = .10) and breast cancer-specific (HR = 1.23, 95% CI = 0.95 to 1.60, P trend = .09) mortality. Also, among women with continued high grilled/barbecued and smoked meat intake after diagnosis, all-cause mortality risk was elevated 31% (HR = 1.31, 95% CI = 0.96 to 1.78). Further, breast cancer-specific mortality was decreased among women with any pre- and postdiagnosis intake of smoked poultry/fish (HR = 0.55, 95% CI = 0.31 to 0.97). High intake of grilled/barbecued and smoked meat may increase mortality after breast cancer. © The Author 2017. Published by Oxford

Smoke-free public places legislation has been introduced in many countries to protect the public from the harmful effects of secondhand smoking. While evaluations of smoke-free policies have demonstrated major public health benefits, the impact on youth smoking and inequalities in smoking remains unclear. This project aims to evaluate how smoke-free public places legislation in the UK has impacted on inequalities in youth smoking uptake, and how much of any impact is via changes in parental smoking behaviour. The study will constitute secondary analyses of UK data (from the British Household Panel Survey and the Understanding Society study). Merging these datasets gives coverage of the period from 1994 to 2016. Missing data will be handled using multiple imputation. The primary outcomes are the rates and inequalities in initiation, experimentation, escalation to daily smoking and quitting among youths aged 11-15 years. Secondary outcomes include the prevalence of smoking among parents of these youths. Discrete-time event history analysis will be conducted to examine whether changes in the probability of youth smoking transitions are associated with the implementation of the smoke-free public places legislation; and whether any observed effects differ by socioeconomic position and parental smoking. A multilevel logistic regression model will be used to investigate whether there is a step change or change in trend for the prevalence of parental smoking after the policy was implemented. The models will be adjusted for relevant factors (including cigarette taxation, the change in the legal age for purchase of cigarettes and e-cigarette prevalence) that may be associated with the implementation of the legislation. This project will use anonymised survey data which have been collected following independent ethical review. The dissemination of the study findings will adopt multiple communication channels targeting both scientific and non-scientific audiences. © Article

OBJECTIVE: In a multigenerational study of smoking risk, the objective was to investigate the intergenerational transmission of smoking by examining if exposure to parental smoking and nicotine dependence predicts prospective smoking trajectories among adolescent offspring. METHODS: Adolescents (n = 406) ages 12 to 17 and a parent completed baseline interviews (2001–2004), and adolescents completed up to 2 follow-up interviews 1 and 5 years later. Baseline interviews gathered detailed information on parental smoking history, including timing and duration, current smoking, and nicotine dependence. Adolescent smoking and nicotine dependence were assessed at each time point. Latent Class Growth Analysis identified prospective smoking trajectory classes from adolescence into young adulthood. Logistic regression was used to examine relationships between parental smoking and adolescent smoking trajectories. RESULTS: Four adolescent smoking trajectory classes were identified: early regular smokers (6%), early experimenters (23%), late experimenters (41%), and nonsmokers (30%). Adolescents with parents who were nicotine-dependent smokers at baseline were more likely to be early regular smokers (odds ratio 1.18, 95% confidence interval 1.05–1.33) and early experimenters (odds ratio 1.04, 95% confidence interval 1.04–1.25) with each additional year of previous exposure to parental smoking. Parents’ current non-nicotine–dependent and former smoking were not associated with adolescent smoking trajectories. CONCLUSIONS: Exposure to parental nicotine dependence is a critical factor influencing intergenerational transmission of smoking. Adolescents with nicotine-dependent parents are susceptible to more intense smoking patterns and this risk increases with longer duration of exposure. Research is needed to optimize interventions to help nicotine-dependent parents quit smoking early in their children’s lifetime to reduce these risks. PMID:24819567

The impact of recent changes in smoke alarm legislation on residential fire injuries and smoke alarm ownership in New South Wales, Australia.

In 2006, New South Wales (NSW) state legislation changed from requiring smoke alarms in new houses only to all houses. We evaluated the impact of this legislative change on residential fire injury and smoke alarm ownership characteristics. Residential fire injuries for 2002 to 2010 were identified from hospitalization data for all hospitals in NSW. Data relating to smoke alarm ownership and demographic factors were obtained from the NSW Population Health Survey. Negative binomial regression analysis was used to analyze trends over time. Prior to the introduction of universal legislation, hospitalization rates were increasing slightly; however, following the introduction of legislation, hospitalization rates decreased by an estimated 36.2% (95% confidence interval [CI], 16.7-55.8) annually. Smoke alarm ownership increased from 73.3% (95% CI, 72.5-74.2) prelegislation to 93.6% (95% CI, 93.1-94.2) 18 months postlegislation. Thirty percent of households reported testing their alarms regularly. Speaking a language other than English (relative risks [RRs], 1.82; 95% CI, 1.44-2.99), allowing smoking in the home (RR, 1.73; 95% CI, 1.31-2.27), and being part of the most disadvantaged socioeconomic group (RR, 1.47; 95% CI, 1.14-1.91) remain major risk factors for nonownership. Broadening the scope of state legislation has had a positive impact on residential fire-related hospitalizations and smoke alarm ownership. However, it is of concern that the legislation has been the least effective in increasing smoke alarm ownership among non-English-speaking households, in households where smoking is allowed, in low socioeconomic households, and that a high proportion of householders do not test their smoke alarms regularly. Targeted campaigns are needed to reach these high-risk groups and to ensure that smoke alarms are functional.

To evaluate the impact of the workplace smoking ban in South Korea, where the male smoking rate is high (57%), on smoking behavior and secondhand smoke exposure. A workplace smoking ban legislation implemented in April 2003 requires offices, meeting rooms, and lobbies located in larger than 3,000 square meter buildings (or 2,000 square meter multipurpose buildings) should be smoke free. A representative cross-sectional survey, the third wave (2005) of health supplements in the National Health Nutrition Survey of South Korea, was used to measure the impact of the 2003 workplace smoking ban implementation on smoking behavior. It contained 3,122 observations of adults 20 to 65 years old (excluding self-employed and non-working populations). A multivariate statistical model was used. The self-reported workplace smoking ban policy (full workplace ban, partial workplace ban, and no workplace ban) was used as the key measure. A full workplace smoking ban reduced the current smoking rate by 6.4 percentage points among all workers and also decreased the average daily consumption among smokers by 3.7 cigarettes relative to no smoking ban. Secondhand smoke showed a dramatic decrease of 86 percent (= -1.74/2.03)from the sample mean for full workplace ban. However, public anti-smoking campaign did not show any significant impact on smoking behavior. The full workplace ban policy is effective in South Korea. Male group showed bigger impact of smoking ban policy than female group. The public antismoking campaign did not show any effectiveness.

We reviewed the number of incidents of tobacco use (almost exclusively smoking) depicted in movies in the United States in 2011 to compare that with previously reported trends. We counted use or implied use of a tobacco product by an actor in all movies whose box office gross ranked in the top 10 for at least 1 week. Total tobacco incidents per movie rose 7% from 2010 to 2011, ending 5 years of decline; incidents rose 34% per movie rated G, PG, or PG-13 and 7% per R-rated movie. The reversal of progress toward less onscreen smoking in youth-rated movies underscores the need to rate movies with tobacco imagery as R, establishing an industry-wide market incentive to keep youth-marketed movies tobacco-free.

Evaluation of the Effects of Rivastigmine on Cigarette Smoking by Methamphetamine-Dependent Volunteers

Compared to smokers alone, smokers with co-morbid substance use disorders are at greater risk of suffering from smoking-related death. Despite this, relatively few studies have examined smoking cessation treatments for those with stimulant dependence. In the current study, we sought to evaluate the effects of produced by short-term exposure to the cholinesterase inhibitor rivastigmine (0, 3 or 6 mg) on cigarette smoking in non-treatment-seeking, methamphetamine-dependent volunteers. This was a double-blind, placebo-controlled, crossover study that took place over 9 days. The data indicate that rivastigmine treatment did not alter Fagerström Test for Nicotine Dependence scores, carbon monoxide readings, or cigarettes smoked per day, but a trend toward reduced urges to smoke (p<0.09) was detected during treatment with rivastigmine 3 mg. These data, while preliminary, indicate that cholinesterase inhibitors warrant further consideration as treatments for nicotine dependence, including use in stimulant-dependent individuals who exhibit significantly higher rates of smoking than the general population.

Perspectives of breast cancer etiology: synergistic interaction between smoking and exogenous hormone use

To explore breast cancer etiology, literature was searched using Medline. We explored the (1) plausibility of smoking in breast Carcinogenesis; (2) physiological properties, susceptibility windows, and exposure timing of breast cells; (3) role of exogenous hormones in breast Carcinogenesis; (4) biological mechanism of synergistic interactions between smoking and exogenous hormones in breast Carcinogenesis; and (5) evidence from epidemiologic studies and the fitted secular trend between smoking rate, exogenous hormone use, and breast cancer incidence in past decades. We deduced that exogenous hormone use per se is not a significant cause and its association with breast cancer is distorted by chronic exposure to environmental carcinogens, especially smoking. We hypothesize that smoking is one of the causes of breast cancer and that this causality is strengthened by synergistic interaction between smoking and exogenous hormone use. Physicians should be cautious of prescribing exogenous hormones for those with chronic exposure to environmental carcinogens to prevent breast cancer. PMID:21718589

The impact of smoking on gender differences in life expectancy: more heterogeneous than often stated

PubMed Central

Wegner-Siegmundt, Christian

2015-01-01

Background: Throughout industrialized countries, tobacco consumption is seen as the predominant driver of both the trend and the extent of gender differences in life expectancy. However, several factors raise doubts to this generalization. We hypothesize that the impact of smoking on the gender gap is context-specific and differs between populations. Methods: We decompose the gender differences in life expectancy into fractions caused by smoking and other non-biological factors for 53 industrialized countries and the period 1955–2009 to assess the significance of smoking among the causes that can be influenced by direct or indirect interference. Results: The trend of the gender gap can indeed be attributed to smoking in most populations of the western world. However, with regard to the overall extent of male excess mortality, smoking is the main driver only in the minority of the studied populations. While the impact of smoking to gender differences in life expectancy declines in all populations, the contribution of other non-biological factors is in most cases higher at the end than at the beginning of the observation period. Conclusions: Over-generalized statements suggesting that smoking is the main driver of the gender gap in all populations can be misleading. The results of this study demonstrate that—regardless of the prevailing effect of smoking—many populations have still remarkable potentials to further narrow their gender gaps in life expectancy. Although measures to further reduce the prevalence of tobacco consumption must be continued, more attention should be directed to the growing importance of other non-biological factors.

Parental smoking is associated with an increased risk of smoking among youth. Epidemiological research has shown that parental smoking cessation can attenuate this risk. This study examined whether telephone counselling for parents and subsequent parental smoking cessation affect smoking-related cognitions and smoking initiation among children of smoking parents. Data of a two-arm randomized controlled trial were used in which 512 smoking parents were recruited into cessation support through their children's primary schools. After the baseline assessment, smoking parents were randomly assigned to tailored telephone counselling or a standard self-help brochure. Parental cessation was measured as 6-month prolonged abstinence at the 12-month follow-up. Children's smoking-related cognitions and smoking initiation were examined at 3-month, 12-month, and 30-month follow-up. No statistical evidence was found that children of parents who received telephone counselling tailored to smoking parents or children of parents who achieved prolonged abstinence differ in smoking-related cognitions (i.e., smoking outcome expectancies, perceived safety of smoking, self-efficacy to refrain from smoking, susceptibility to smoking) or smoking initiation rate on any follow-up assessment. This study is the first to examine the effects of an evidence-based smoking cessation treatment for parents and treatment-induced parental smoking cessation on cognitive and behavioural outcomes among children. Although descriptive statistics showed lower smoking initiation rates among children of parents who achieved prolonged abstinence, there was no statistical evidence that telephone counselling tailored to parents or treatment-induced parental smoking cessation affects precursors of smoking or smoking initiation among youth.

The objective of this study was to examine changes in the annual number of cigarette advertisements in magazines with a predominantly African-American audience following the broadcast ban on tobacco, and whether fluctuations in cigarette print advertising targeting African Americans during the late-1970s until the mid-1980s were associated with declines in smoking initiation. We tabulated the annual number of cigarette advertisements from magazines with large African-American readerships (Ebony, Essence, and Jet) from 1960 to 1990. Advertisements were coded depending on whether they featured African-American models. We calculated the incidence rate of regular smoking initiation from 1975 to 1990 for African-American 14-25 years old using data from the 1992-1993, 1995-1996, 1998-1999, and 2001-2002 Tobacco Use Supplements of the Current Population Survey. We examined whether trends in smoking initiation coincided with trends in cigarette advertising practices among African Americans. The annual aggregated number of printed cigarette advertisements in Ebony, Essence, and Jet magazines increased at least five-fold starting in 1971, following the broadcast ban on cigarette advertising. A decrease in the percentage of ads by Brown & Williamson that showed African-American models was positively correlated (r = 0.30) with declines in the incidence rate of smoking initiation among African Americans from the late-1970s to the mid-1980s. The tobacco industry adapted quickly following the broadcast ban on cigarettes by increasing print advertising in African-American magazines. However, changes in print advertising practices by were associated with declines in smoking initiation among African Americans from the late-1970s to mid-1980s.

SMOKING CESSATION INTERVENTIONS FOR HOSPITALIZED SMOKERS: A SYSTEMATIC REVIEW

Rigotti, Nancy A.; Munafo, Marcus R.; Stead, Lindsay F.

2009-01-01

Background A hospital admission provides an opportunity to help people stop smoking. Providing smoking cessation advice, counselling, or medication is now a quality-of-care measure for U.S. hospitals. We assessed the effectiveness of smoking cessation interventions initiated during a hospital stay. Methods We searched the Cochrane Tobacco Addiction Review Group's register for randomized and quasi-randomized controlled trials of smoking cessation interventions (behavioral counselling and/or pharmacotherapy) that began during hospitalization and had a minimum of 6 months follow-up. Two authors independently extracted data from each paper, with disagreements resolved by consensus. Results 33 trials met inclusion criteria. Smoking counselling that began during hospitalization and included supportive contacts for >1 month after discharge increased smoking cessation rates at 6-12 months (pooled OR 1.65, 95% CI 1.44-1.90). No benefit was found for interventions with less post-discharge contact. Counselling was effective when offered to all hospitalized smokers and to the subset admitted for cardiovascular disease. Adding nicotine replacement therapy to counselling produced a trend toward efficacy over counseling alone (OR 1.47, 95% CI 0.92-2.35). One study added bupropion to counselling. It had a nonsignificant result (OR 1.56, 95% CI 0.79-3.06). Conclusions Offering smoking cessation counselling to all hospitalized smokers is effective as long as supportive contacts continue for >1 month after discharge. Adding NRT to counselling may further increase smoking cessation rates and should be offered when clinically indicated, especially to hospitalized smokers with nicotine withdrawal symptoms.

Unit record data from five population-based surveys (n = 14 528) allowed classification of participants as: (1) never-smoker, ex-smoker, or non-daily smoker; or (2) daily smoker, reporting smoking <20 or ≥20 tobacco products (cigarettes/cigars/pipes) a day. Trends were examined using spline analyses. Over 1980-2011 the prevalence of reported daily tobacco smoking decreased significantly in both sexes and ethnicities, with the greatest decline during 1980-2000. Declines were from 81.7% to 27.0% in i-Taukei men; 55.3% to 26.3% in Indian men; 48.1% to 9.5% in i-Taukei women; and 13.8% to 1.3% in Indian women (p < .0001). Declines were consistent across all age groups in men, while there were greater declines among older age groups in women; and greater declines from higher prevalences in rural compared to urban areas in both sexes and ethnicities. Smoking ≥20 tobacco products per day declined significantly in i-Taukei men from 8.0% to 1.9% (p < .0001); there were also declines in Indian men (4.6% to 2.0%) and i-Taukei women (2.6% to 0.6%), but these were not statistically significant; and Indian women remained <0.2% throughout the period. Significant declines in daily tobacco smoking have occurred in Fiji in both sexes and ethnicities during the past 30 years, which is consistent with declines in tobacco apparent consumption and household expenditure. However, prevalence remains high in men at around 27% in 2011, with plateau at this level in i-Taukei. This is the first study to show nationally representative population trends in tobacco smoking in a developing country over such a long period (>30 years) based on empirical unit record data (n = 14 528).

Lawsuits and secondhand smoke.

PubMed

Sweda, E L

2004-03-01

This paper describes secondhand smoke (SHS) litigation over the past quarter century where non-smoking litigants have prevailed and attempts to decipher trends in the law that may impact the course of future cases. Since the early 1980s, the author has sought and examined legal cases in which SHS exposure is an important factor. Law library searches using the official reporter system (for example, Shimp v. New Jersey Bell Telephone Co., 368 A.2d 408) have more recently been combined with computerised online searches using LexisNexis and Westlaw. The author has learned of other cases through personal correspondence and from articles in newspapers. Over 420 cases involving exposure to SHS were identified. Each case was reviewed and summarised. Since 1976, the year of the first reported SHS lawsuit, this type of litigation has increased both in number and in scope with increasing success. While it is common for initial cases to lose in a new area where the law eventually evolves, litigants and their lawyers who later bring similar cases can learn from those previous, unsuccessful cases. It is now apparent that the judicial branch has begun to recognise the need to protect the public-especially some of the most vulnerable members of our society-from the serious threat to their health that is exposure to SHS. Successful cases brought on behalf of individuals exposed to SHS produce an additional benefit for the public health by both paving the way for other non-smoking litigants to succeed in their cases and persuading business owners and others voluntarily to make their facilities 100% smoke-free.

In this narrative review, we explore the history of tobacco smoking, its associations and portrayal of its use with luxury and glamour in the past, and intriguingly, its subsequent transformation into a mass consumption industrialized product encouraged by advertising and film. Then, we describe the next phase where tobacco in parts of the world has become an unwanted product. However, the number of smokers is still increasing, especially in new markets, and increasingly younger individuals are being attracted to it, despite the well-known health consequences of tobacco use. We also explore current smoking behaviors, looking at trends in the prevalence of consumption throughout the world, discrimination against smokers, light and/or intermittent smokers, and the electronic cigarette (e-cigarette). We place these changes in the context of neuroscience, which may help explain why the cognitive effects of smoking can be important reinforcers for its consumption despite strong anti-smoking pressure in Western countries. © 2015 The Authors.

OBJECTIVE: To describe a new murine model of cigarette smoke-induced emphysema. METHODS: Twenty-four male Wistar rats were divided into two groups: the cigarette smoke group, comprising 12 rats exposed to smoke from 12 commercial filter cigarettes three times a day (a total of 36 cigarettes per day) every day for 30 weeks; and the control group, comprising 12 rats exposed to room air three times a day every day for 30 weeks. Lung function was assessed by mechanical ventilation, and emphysema was morphometrically assessed by measurement of the mean linear intercept (Lm). RESULTS: The mean weight gain was significantly (approximately ten times) lower in the cigarette smoke group than in the control group. The Lm was 25.0% higher in the cigarette smoke group. There was a trend toward worsening of lung function parameters in the cigarette smoke group. CONCLUSIONS: The new murine model of cigarette smoke-induced emphysema and the methodology employed in the present study are effective and reproducible, representing a promising and economically viable option for use in studies investigating the pathophysiology of and therapeutic approaches to COPD.

The objective of this study was to systemically and comprehensively evaluate the associations between smoking and disease outcomes in patients with ankylosing spondylitis (AS). Information on smoking, clinical features, and sociodemographic characteristics was collected by a questionnaire administered directly to the patient. Group differences were analyzed by t test or chi-square test. Logistic regression analysis was conducted with the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), C-reactive protein, and erythrocyte sedimentation rate as the dependent variables and different stratification of smoking duration, smoking intensity, and cumulative smoking as independent variables. In order to compare our results with previous studies, meta-analysis was performed to calculate standardized mean difference (SMD) for relationship between outcomes and smoking status. A total of 1178 AS patients were analyzed. Compared with non-smokers, the risk of having active disease (BASDAI ≥ 4) was higher in patients who smoked at least 15 years, or 15 cigarettes per day, or 15 pack-years (OR = 1.70 [1.06, 2.73], 1.75 [1.08, 2.82], and 1.97 [1.06, 3.67], respectively); and smokers had increasing risk of BASDAI ≥ 4 with increasing years of smoking, or cigarettes per day, or pack-years (p -trend  = 0.010, 0.008 and 0.006, respectively). The risk of having active disease was higher in patients who smoked at least 15 cigarettes per day or 15 pack-years (OR = 1.74 [1.06, 2.84] and 2.89 [1.56, 5.35], respectively), with increasing number of cigarettes per day and pack-years. Smokers had an increased risk of BASFI ≥ 4 (p -trend  = 0.040 and 0.007, respectively). By meta-analysis, current, former and ever smokers had significantly higher BASDAI (SMD = 0.34 [0.18, 0.48], 0.10 [0.01, 0.19], and 0.27 [0.20, 0.34], respectively) and BASFI (SMD = 0.35 [0.16, 0.55], 0.30 [0.22, 0.39], and 0.35 [0.21, 0.50], respectively) compared to

Background Longitudinal studies from the U.S. suggest a causal relationship between exposure to images of smoking in movies and adolescent smoking onset. Purpose This study investigates whether adolescent smoking onset is predicted by the amount of exposure to smoking in movies across six European countries with various cultural and regulatory approaches to tobacco. Methods Longitudinal survey of 9987 adolescent never-smokers recruited in the years 2009–2010 (mean age 13.2 years) in 112 state-funded schools from Germany, Iceland, Italy, The Netherlands, Poland, and the United Kingdom (UK), and followed-up in 2011. Exposure to movie smoking was estimated from 250 top-grossing movies in each country. Multilevel mixed-effects Poisson regressions were performed in 2012 to assess the relationship between exposure at baseline and smoking status at follow-up. Results During the observation period (M=12 months), 17% of the sample initiated smoking. The estimated mean exposure to on-screen tobacco was 1560 occurrences. Overall, and after controlling for age; gender; family affluence; school performance; TVscreen time; personality characteristics; and smoking status of peers, parents, and siblings, exposure to each additional 1000 tobacco occurrences increased the adjusted relative risk for smoking onset by 13% (95% CI=8%, 17%, p<0.001). The crude relationship between movie smoking exposure and smoking initiation was significant in all countries; after covariate adjustment, the relationship remained significant in Germany, Iceland, The Netherlands, Poland, and UK. Conclusions Seeing smoking in movies is a predictor of smoking onset in various cultural contexts. The results confirm that limiting young people’s exposure to movie smoking might be an effective way to decrease adolescent smoking onset. PMID:23498098

Objective To examine the associations of perceived interparental relationship, family harmony and family happiness with smoking intention in never-smoking Chinese children and adolescents in Hong Kong. Design, settings and participants Cross-sectional surveys of 15 753 primary (grades 4–6) and 38 398 secondary (grades 7–12) never-smoking students from 71 to 75 randomly selected primary and secondary schools in Hong Kong, 2012–2013. Measurements Outcome variable was smoking intention which denoted any affirmative response to smoke within the coming year or when a cigarette was offered by a good friend. Exposure variables were perceived interparental relationship and family harmony each measured on a five-point scale from ‘very good’ to ‘very bad’ and perceived family happiness on a four-point scale from ‘very happy’ to ‘not happy at all’. Potential confounders included age, sex, family structure, perceived family affluence, parental smoking and sibling smoking. Results In primary students, the adjusted ORs (AORs) (95% CI) of smoking intention generally increased with more negative perception of the family relationship: up to 3.67 (1.91 to 7.05) for interparental relationship, 7.71 (4.38 to 13.6) for family harmony and 5.40 (3.41 to 8.55) for family happiness. For secondary students, the corresponding AORs (95% CI) were 2.15 (1.64 to 2.82) for interparental relationship, 2.98 (2.31 to 3.84) for family harmony and 2.61 (1.80 to 3.79) for family happiness. All p for trend <0.001. Conclusions More negatively perceived interparental relationship, family harmony and family happiness were associated with higher odds of smoking intention with dose–response relationships in never-smoking Chinese children and adolescents in Hong Kong. Children’s perception of their family relationship may be an important intervening point for preventing youth from initiating smoking. PMID:28988179

Detailed lipidomics experiments were performed on the extracts of cured tobacco leaf and of cigarette smoke condensate (CSC) using high-resolution liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC-Q-TOF MS). Following automated solid-phase extraction (SPE) fractionation of the lipid extracts, over 350 lipids could be annotated. From a large-scale study on 22 different leaf samples, it was determined that differentiation based on curing type was possible for both the tobacco leaf and the CSC extracts. Lipids responsible for the classification were identified and the findings were correlated to proteomics data acquired from the same tobacco leaf samples. Prediction models were constructed based on the lipid profiles observed in the 22 leaf samples and successfully allowed for curing type classification of new tobacco leaves. A comparison of the leaf and CSC data provided insight into the lipidome changes that occur during the smoking process. It was determined that lipids which survive the smoking process retain the same curing type trends in both the tobacco leaf and CSC data. Copyright © 2015 Elsevier B.V. All rights reserved.

We have previously published a forecasting model of future smoking prevalence in New Zealand (NZ). Under business-as-usual (BAU) assumptions NZ's smokefree 2025 goal was not attained by any demographic group. However, the 2013 Census (which included a question on smoking) showed a greater than expected fall in prevalence, especially for Maori. We therefore aimed to provide upgraded projections to inform policy around tobacco endgame planning. The previously developed dynamic forecasting model was re-specified using smoking prevalence data from the 2006 and 2013 censuses from NZ. Calculations included changes in initiation by age 20 years, and net annual cessation rates, by sex, age, and ethnicity (Maori vs non-Maori). Projections under 2006-2013 trends (adjusted for no tax rises since 2010), by sex and ethnicity were made out to 2025 and beyond. Between the 2006 and 2013 censuses (adjusted for no tax rises since 2010), initiation of daily smoking by age 20 years decreased annually by 3.4% (95% uncertainty interval 3.2% to 3.6%) and 2.7% (2.5% to 2.8%) for non-Maori men and women, and by 2.9% (2.6% to 3.2%) and 3.2% (2.9% to 3.5%) for Maori respectively. Annual net smoking cessation rates ranged from 3.7% to 7.7% across demographic groups. The revised projected smoking prevalence in 2025 (allowing for tax increases that have occurred from 2010 to 2014) was 8.3% and 6.4% for non-Maori, and 18.7% and 19.3% for Maori men and women, respectively. The upgraded smoking prevalence projections still suggests that the NZ Government's smokefree 2025 goal would not be attained by any demographic group. It is likely that more intensive existing interventions, or entirely novel ones, will be needed to achieve the 2025 endgame goal.

The social definition of women's smoking behaviour.

PubMed

Elkind, A K

1985-01-01

The history of women's smoking behaviour is one of changing normative definitions. Recent trends have been explained in terms of the symbolic value of smoking, representing for women freedom and independence. This view is emphasised by advertising. However, other evidence suggests the continued existence of an older, more negative cultural stereotype. A two-part study of young women undergoing professional training for nursing and teaching throws some light on the way in which female smoking behaviour is currently socially interpreted. The first phase indicated that among the minority of parents who had expressed their attitudes towards their daughter's smoking in relation to sex-role norms, smoking was presented as unacceptable for women. More than half the sample perceived a negative cultural stereotype to be operating in contemporary society and two-thirds recognised its existence in the past. This stereotype presents smoking as a male behaviour and hence inappropriate for women. Women who do smoke are liable to be labelled as having unfeminine or degrading attributes. The stereotype operated more strongly in the general social background rather than in reference to personal relationships and hence its influence on contemporary behaviour is likely to be limited. It was rejected as out-dated or a male belief by some but nevertheless it represented the personal opinion of others. In terms of a more favourable definition the female smoker was perceived in terms of an elegant/sophisticated dimension and in relation to an extrovert personality. The view of sample members that the growing acceptability of women's smoking was related to social change indirectly supported the view that sees smoking as symbolic of independence. Those who saw smoking in neutral terms, i.e. as not having sex-role attributes, perceived smoking in this sense as normal social behaviour for men and women alike. The second phase suggested that smokers and non-smokers have divergent views about

Smoking in the movies increases adolescent smoking: a review.

Despite voluntary restrictions prohibiting direct and indirect cigarette marketing to youth and paid product placement, tobacco use remains prevalent in movies. This article presents a systematic review of the evidence on the nature and effect of smoking in the movies on adolescents (and others). We performed a comprehensive literature review. We identified 40 studies. Smoking in the movies decreased from 1950 to approximately 1990 and then increased rapidly. In 2002, smoking in movies was as common as it was in 1950. Movies rarely depict the negative health outcomes associated with smoking and contribute to increased perceptions of smoking prevalence and the benefits of smoking. Movie smoking is presented as adult behavior. Exposure to movie smoking makes viewers' attitudes and beliefs about smoking and smokers more favorable and has a dose-response relationship with adolescent smoking behavior. Parental restrictions on R-rated movies significantly reduces youth exposure to movie smoking and subsequent smoking uptake. Beginning in 2002, the total amount of smoking in movies was greater in youth-rated (G/PG/PG-13) films than adult-rated (R) films, significantly increasing adolescent exposure to movie smoking. Viewing antismoking advertisements before viewing movie smoking seems to blunt the stimulating effects of movie smoking on adolescent smoking. Strong empirical evidence indicates that smoking in movies increases adolescent smoking initiation. Amending the movie-rating system to rate movies containing smoking as "R" should reduce adolescent exposure to smoking and subsequent smoking.

Despite the historically low smoking prevalence among Chinese women, there is a trend of future increase. We systematically reviewed the correlates of smoking among Chinese girls and women. We conducted a systematic review of literature on correlates of smoking among Chinese women using Medline and China Academic Journals databases. Following the PRISMA statement, two investigators independently searched for literature, identified and reviewed papers, assessed the quality of the papers, and extracted information. The characteristics of studies and correlates of smoking were synthesized separately for youth and adults. A total of 15 articles (11 on adults, 4 on youth) met the inclusion criteria. Based on these studies, peer smoking was the most consistent correlate of smoking among Chinese girls. Among Chinese women, partner smoking, job-related stress, and exposure to cigarettes made for women were consistent correlates of smoking. Knowledge of harms and negative attitudes towards smoking were found to be negatively associated with smoking. Overall, the evidence base for smoking among Chinese women is limited. Although smoking among Chinese women is still at an early stage, it is becoming more prevalent among specific population subgroups, such as rural-to-urban migrant workers. Although further research is needed, findings from the current study provide a roadmap for research and policy on prevention of smoking among Chinese girls and women.

Although differing levels of family influences may explain some of the varying racial/ethnic trends in adolescent smoking behavior, clarification of which influences are protective against smoking may aid in the development of future ethnic-specific smoking prevention interventions. We sought to identify and compare the association of family influences on adolescent smoking among Black, Hispanic, and White adolescents in a cross-sectional national sample. Data from 6,426 parent-child dyads from Round 1 of the National Survey of Parents and Youth were analyzed. The association of family influences with ever-smokers and recent smokers was evaluated. Multinomial logistic regression using SUDAAN software was used. While all measures of family influences except for parent-adolescent activities and intention to monitor were significantly protective against recent smoking and ever smoking among Whites, ethnic-specific family influence predictors of smoking were found in Blacks and Hispanics. Higher parental monitoring, higher intention to monitor, and higher connectedness were protective among Hispanics, while higher parental punishment and favorable attitude toward monitoring were protective against smoking among Blacks. For family influences significantly associated with protection against smoking, consistently greater protection was afforded against recent smoking than against ever smoking. Higher levels of family influences are protective against smoking among all racial/ethnic groups. There are consistencies in family influences on youth smoking; however, there may be specific family influences that should be differentially emphasized within racial/ethnic groups in order to protect against smoking behavior. Our results offer insight for designing strategies for preventing smoking in youth of different racial/ethnic backgrounds.

In early 2000, the American Legacy Foundation launched the national "truth" campaign, the first national antismoking campaign to discourage tobacco use among youths. We studied the impact of the campaign on national smoking rates among US youths (students in grades 8, 10, and 12). We used data from the Monitoring the Future survey in a pre/post quasi-experimental design to relate trends in youth smoking prevalence to varied doses of the "truth" campaign in a national sample of approximately 50000 students in grades 8, 10, and 12, surveyed each spring from 1997 through 2002. Findings indicate that the campaign accounted for a significant portion of the recent decline in youth smoking prevalence. We found that smoking prevalence among all students declined from 25.3% to 18.0% between 1999 and 2002 and that the campaign accounted for approximately 22% of this decline. This study showed that the campaign was associated with substantial declines in youth smoking and has accelerated recent declines in youth smoking prevalence.

Beliefs about smoking are important predictors of smoking behavior among adolescents, and adolescents who hold positive beliefs about the benefits of smoking are at an increased risk of smoking initiation. An alarming fact is the rising smoking prevalence in Asian countries, particularly the increasing trend in smoking during adolescence. This cross-sectional study examined smoking beliefs and behavior among a nationally representative sample of youth in South Korea, Taiwan, and Thailand. Descriptive statistics, linear regression, and logistic regression methods were used to analyze data from 13-15-year-old adolescents who participated in the 2005 Global Youth Tobacco Survey (GYTS) in South Korea (N = 4,765) and Thailand (N = 15,420) and the 2007 GYTS in Taiwan (N = 3,955). The rate of ever smoking among youth was similar in all three countries and ranged from 26.7 to 28.0 %. The prevalence of current smoking among youth in Thailand (11.4 %) was nearly double the prevalence in South Korea (6.6 %) and Taiwan (6.5 %). Pro-tobacco advertising exposure, as well as older ages, was a positive and significant predictor of positive beliefs about smoking among youth in all three countries. Additionally, youth who reported increased positive smoking-related beliefs, greater pro-tobacco advertising exposure, and were male were more likely to be current smokers in all three countries. Results suggest that greater attention be directed to understanding beliefs and attitudes about smoking among youth. Exploring the relationship between these factors and smoking behavior can provide a strong starting point in the development of effective smoking prevention interventions and tobacco control policies in this region.

Smoking in Top-Grossing US Movies, 2011

2012-01-01

We reviewed the number of incidents of tobacco use (almost exclusively smoking) depicted in movies in the United States in 2011 to compare that with previously reported trends. We counted use or implied use of a tobacco product by an actor in all movies whose box office gross ranked in the top 10 for at least 1 week. Total tobacco incidents per movie rose 7% from 2010 to 2011, ending 5 years of decline; incidents rose 34% per movie rated G, PG, or PG-13 and 7% per R-rated movie. The reversal of progress toward less onscreen smoking in youth-rated movies underscores the need to rate movies with tobacco imagery as R, establishing an industry-wide market incentive to keep youth-marketed movies tobacco-free.

The first longitudinal investigation of the extent to which same-age and older schoolmates' smoking and non-smoking are associated with adolescents' smoking transitions during three grade intervals. Same-age and older schoolmates' smoking and non-smoking were assessed when adolescents were at grades 5 (age 10), 7 (age 12) and 9 (age 14). Adolescents' smoking transitions were assessed at three grade intervals: 5th-7th (age 10-12), 7th-9th (age 12-14) and 9th-12th (age 14-17). Forty Washington State school districts. Smoking questionnaire data were gathered on a cohort of adolescents (n = 4354 for same-age schoolmate analysis; n = 1833 for older schoolmate analysis) that was 49% female and 91% Caucasian. No significant evidence that same-age schoolmates' smoking or non-smoking was associated with any of the adolescent smoking transitions at any of the three grade intervals. In contrast, the probability that each older schoolmate's smoking was associated with the adolescent making the transition to trying smoking was 1% (95% CI: 0.4%, 1.5%) and with the transition from trying to monthly smoking was also 1% (95% CI: 0.2%, 2.0%) during the 7th-9th grade (age 12-14) interval. Moreover, each older schoolmate's non-smoking was associated with a 1.001-1.006 (all P < 0.05) relative risk of an adolescent not trying smoking or escalating from trying to monthly smoking at several grade intervals. Interventions should perhaps focus on the influence of both smoking and non-smoking older schoolmates during late childhood and early adolescence.

Urban middle-socioeconomic status (SES) subjects have high burden of cardiovascular risk factors in low-income countries. To determine secular trends in risk factors among this population and to correlate risks with educational status we performed epidemiological studies in India. Five cross-sectional studies were performed in middle-SES urban locations in Jaipur, India from years 1992 to 2010. Cluster sampling was performed. Subjects (men, women) aged 20-59 years evaluated were 712 (459, 253) in 1992-94, 558 (286, 272) in 1999-2001, 374 (179, 195) in 2002-03, 887 (414, 473) in 2004-05, and 530 (324, 206) in 2009-10. Data were obtained by history, anthropometry, and fasting blood glucose and lipids estimation. Response rates varied from 55 to 75%. Mean values and risk factor prevalence were determined. Secular trends were identified using quadratic and log-linear regression and chi-squared for trend. Across the studies, there was high prevalence of overweight, hypertension, and lipid abnormalities. Age- and sex-adjusted trends showed significant increases in mean body mass index (BMI), fasting glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides (quadratic and log-linear regression, p < 0.001). Systolic blood pressure (BP) decreased while insignificant changes were observed for waist-hip ratio and low-density lipoprotein (LDL) cholesterol. Categorical trends showed increase in overweight and decrease in smoking (p < 0.05); insignificant changes were observed in truncal obesity, hypertension, hypercholesterolaemia, and diabetes. Adjustment for educational status attenuated linear trends in BMI and total and LDL cholesterol and accentuated trends in systolic BP, glucose, and HDL cholesterol. There was significant association of an increase in education with decline in smoking and an increase in overweight (two-line regression p < 0.05). In Indian urban middle-SES subjects there is high prevalence of cardiovascular risk

A Symbolic Interaction Approach to Cigarette Smoking: Smoking Frequency and the Desire to Quit Smoking

This study applies a symbolic interaction perspective to the investigation of smoking frequency and a person’s desire to quit smoking cigarettes. Data derived from 485 Atlanta area adult smokers provide a diverse, community-based sample of married and single men and women, aged 18 to 70 years old with a range of income, education, and occupational experiences. Multiple regression was used to analyze the data in order to explore the influence of social demographic characteristics, social interaction, subjective assessments of health, self conceptions, and smoker identity on smoking frequency and quitting smoking. Findings include: (1) the relationship with a non-smoker and hiding smoking negatively impacted smoking frequency, while perceiving positive consequences from smoking has a positive effect on smoking frequency; and (2) perceiving positive consequences of smoking was negatively related to the desire to quit smoking, while a negative smoker identity has a positive influence on the desire to quit. Taken as a whole, the symbolic interaction-inspired variables exerted strong and independent effects on both smoking frequency and quitting smoking. Future smoking interventions should focus on meanings and perceived consequences of smoking in general, and on the smoker identity in the development of campaigns to encourage quitting cigarette smoking.

Objectives. Because household smoking levels and adoption of domestic smoking rules may be endogenously related, we estimated a nonrecursive regression model to determine the simultaneous relationship between home smoking restrictions and household smoking. Methods. We used data from a May–June 2012 survey of Philadelphia, Pennsylvania, households with smokers (n = 456) to determine the simultaneous association between smoking levels in the home and the presence of home restrictions on smoking. Results. We found that home smoking rules predicted smoking in the home but smoking in the home had no effect on home smoking restrictions. Conclusions. Absent in-home randomized experiments, a quasi-experimental causal inference suggesting that home smoking rules result in lower home smoking levels may be plausible. PMID:24524533

Is the smoking decision an 'informed choice'? Effect of smoking risk factors on smoking beliefs.

PubMed

Leventhal, H; Glynn, K; Fleming, R

1987-06-26

The argument that people freely choose to smoke assumes that individuals at the point of initiation of smoking (often in adolescence) hold accurate beliefs about smoking. Smoking beliefs and the presence of known smoking risk factors were assessed in interviews with a sample of 895 urban young people. The respondents greatly overestimated the prevalence of adult and peer smoking, negative attitudes of their peers were greatly underestimated, a large proportion believed that they would be less likely than other people to contract a smoking-related illness if they became smokers, and there was a general lack of understanding of the adverse consequences experienced upon smoking cessation. These misperceptions were more common among youngsters who were smokers, who intended to smoke, or who had friends or family members who smoked. Because misinformation among young people is widespread and those at greatest risk for smoking are the most misinformed, the tobacco industry's argument that the decision to smoke reflects an "informed choice" is without merit.

[Smoking in movies and established smoking in adolescence].

The aim of this study was to examine whether smoking in movies can predict established smoking in adolescence. A longitudinal study was conducted over a period of 13 months with 4112 German students. Adolescents' exposure to smoking in movies was assessed by asking each student to indicate which film he or she had seen from a unique list of 50 movies, which was randomly selected for each individual survey from a sample of 398 popular contemporary movies. We calculated exposure to movie smoking for each respondent by summing the number of smoking occurrences for each movie that the respondent reported seeing. At follow-up, a total of 272 young people had smoked more than 100 cigarettes during their lifetime. While 2.1% of the young people with the lowest exposure to movie smoking initiated established smoking, 13.4% of the group with the highest exposure to movie smoking initiated established smoking. The adjusted relative risk of initiation of established smoking was 2.05 times higher in the group with the highest movie smoking exposure compared to the group with the lowest exposure (95% confidence interval: 1.25-3.35). Our data indicate that smoking in movies can be regarded as an independent risk factor for the initiation of established smoking in adolescence. © Georg Thieme Verlag KG Stuttgart · New York.

This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

This study assessed whether smoking in the movies was associated with smoking in young adults. A national web-enabled cross-sectional survey of 1528 young adults, aged 18-25, was performed between September and November 2005. Logistic regression and path analysis using probit regression were used to assess relationships between exposure to smoking in the movies and smoking behavior. Analysis was completed in December 2006. Exposure to smoking in the movies predicted current smoking. The adjusted odds of current smoking increased by a factor of 1.21 for each quartile increase in exposure to smoking (p<0.01) in the movies, reaching 1.77 for the top exposure quartile. The unadjusted odds of established smoking (100+ cigarettes with current smoking) increased by 1.23 per quartile (p<0.001) of exposure, reaching 1.86 for the top quartile. This effect on established smoking was mediated by two factors related to smoking in the movies: positive expectations about smoking and exposure to friends and relatives who smoked, with positive expectations accounting for about two thirds of the effect. The association between smoking in the movies and young adult smoking behavior exhibited a dose-response relationship; the more a young adult was exposed to smoking in the movies, the more likely he or she would have smoked in the past 30 days or have become an established smoker.

It is known that exposure to smoking cues increases urge to smoke (UTS), but little is known about other media factors that might also increase UTS. We hypothesized that horror/thriller movies might also increase UTS by increasing negative affect. We surveyed 536 movie patrons who were smokers aged 18 years or older. Subjects had exited 26 movies, of which 12 contained smoking and two were horror films, one with and one without smoking. We used random effects regression to assess the association between exposure to movie smoking, movie horror, both and UTS, controlling for confounding factors. Median age was 26 years and 52% were female. Mean UTS was 5.9, 6.6, 6.6, and 8.7 for smokers exiting movies without smoking, with smoking, horror without smoking and horror with smoking respectively. Smoking in movies was associated with a significantly higher UTS (0.63 [95% CI 0.31–0.94]). Horror with smoking increased UTS by 2.8 points (95% C.I. 2.3, 3.5); the horror without smoking estimate was 0.88, but not statistically significant. This short report offers preliminary evidence that movie horror as one factor besides visual smoking cues that could increase UTS in a community setting. PMID:20301876

Objectives This study aims to examine current hookah users’ perceptions, attitudes, and normative beliefs regarding hookah smoking to further elucidate the rise in hookah smoking prevalence among young adults (aged 18–24 years) and reveal why hookah smoking is perceived as less harmful than other forms of tobacco consumption. Study Design Qualitative. Methods Data analysis of six focus group interviews with hookah smokers between 18–24 years was analyzed using a grounded theory approach. Focus groups were evenly split between frequent and infrequent hookah users, and were predominantly composed of college students, with two groups of hookah users consisting of 18–24 year olds of non-student status. Results Hookah users shared a much larger set of positive hookah smoking behavioral beliefs as opposed to negative behavioral beliefs. Generational traits served as the overarching commonality among the behavior performance initiation determinants observed. The most notable generational trends observed were within the cultural category, which included the following millennial characteristics: autonomy, personalization, novelty appeal, convenience, globally oriented, entertainment, collaboration, health conscious, and valuing their social network. Conclusions Millennial hookah users revealed mindfulness regarding both potential negative and positive reasons stemming from continued hookah use; however, behavioral beliefs were primarily fixated on the perception that hookah smoking was a healthier alternative to cigarette smoking. Future implications for this study’s findings include generating more positive ways to express these traits for young adults; policy implications include raising hookah bar age limits, implementing indoor smoking restrictions, and limiting the ease of accessibility for purchasing hookah supplies.

In recent decades there has been an increased focus on non-pharmacological treatment of diabetes. The aim of this study was to investigate trends in leisure time physical activity (PA), smoking, body mass index (BMI), and alcohol consumption reported in 2000, 2005 and 2010 by Danish subjects with diabetes. Data comprised level of leisure time PA (inactive; moderate active; medium active; high active); smoking; BMI; and alcohol consumption, provided by The Danish Health and Morbidity Surveys. Participants older than 45 years with or without diabetes were included from cross-sectional analyses from 2000, 2005 and 2010. In participants with diabetes, leisure time PA levels increased from 2000 to 2010: The percentage of those that were physically active increased from 53.5% to 78.2% (p<0.001; women) and from 67.8% to 79.1% (p=0.01; men). The prevalence of daily smokers was reduced from 27.2% to 16.4%, p=0.015, in women with diabetes. In men with diabetes, BMI increased from 27.2 ± 4.0 to 28.6 ± 5.1 kgm(-2), p=0.003, and men who exceeded the maximum recommendation for alcohol consumption increased from 9.4% to 19.0%, p=0.007. The leisure time PA level was reduced in participants with diabetes compared to participants without diabetes throughout the study. The percentage of physically active Danish participants older than 45 years with diabetes increased from 2000 to 2010, and the most beneficial trends in life style were observed among the women. These trends may have serious implications for cardiovascular risk in Danish patients with diabetes. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

To estimate the prevalence of tobacco use, exposure to secondhand smoke, and smoking restrictions in the home and workplace among residents of Tijuana, one of Mexico's largest cities. This cross-sectional household survey was conducted in Tijuana, Baja California, Mexico, during 2003 and 2004. A population-based sample of 400 Tijuana adult residents responded to a tobacco survey, and 397 of the surveys were analyzed. About 22.9% (95% confidence interval (CI): 18.7%-27.1%) of Tijuana adults reported current smoking, and 53.9% (95% CI: 48.8%-58.9%) reported chronic exposure to secondhand smoke. Approximately 44.4% (95% CI: 37.9%-50.9%) of Tijuana adults had a nonsmoking policy in their workplace, while 65.8% (95% CI: 61.0%-70.6%) of Tijuana households were smoke-free. The results underline the need for increased tobacco control efforts, particularly stricter enforcement of existing passive smoking regulations, in order to expand protection from secondhand smoke from private settings to public ones and to curb the tobacco epidemic in Tijuana and elsewhere in Mexico.

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.

Abstract Introduction: Waterpipe tobacco smoking is a global health concern. Laboratory research has focused on individual waterpipe users while group use is common. This study examined user toxicant exposure and smoke toxicant yield associated with individual and group waterpipe smoking. Methods: Twenty-two pairs of waterpipe smokers used a waterpipe individually and as a dyad. Before and after smoking, blood was sampled and expired carbon monoxide (CO) measured; puff topography was recorded throughout. One participant from each pair was selected randomly and their plasma nicotine and expired air CO concentrations were compared when smoking alone to when smoking as part of a dyad. Recorded puff topography was used to machine-produce smoke that was analyzed for toxicant content. Results: There was no difference in mean plasma nicotine concentration when an individual smoked as part of a dyad (mean = 14.9ng/ml; standard error of the mean [ SEM ] = 3.0) compared to when smoking alone (mean = 10.0ng/ml; SEM = 1.5). An individual smoking as part of as a dyad had, on average, lower CO (mean = 15.8 ppm; SEM = 2.0) compared to when smoking alone (mean= 21.3 ppm; SEM = 2.7). When two participants smoked as a dyad they took, on average, more puffs (mean = 109.8; SEM = 7.6) than a singleton smoker (mean = 77.7; SEM = 8.1) and a shorter interpuff interval (IPI; dyad mean = 23.8 seconds; SEM = 1.9; singleton mean = 40.8 seconds; SEM = 4.8). Higher concentrations of several toxicants were observed in dyad-produced smoke. Discussion: Dyad smoking may increase smoke toxicant content, likely due to the dyad’s shorter IPIs and greater puff number. More work is needed to understand if group waterpipe smoking alters the health risks of waterpipe tobacco smoking. Implications: This study is the first to measure toxicants in smoke generated from a waterpipe when used by a dyad. Relative to smoke generated by a singleton, dyad smoke had higher concentration of some toxicants. These

Background In the absence of comprehensive smoking bans in public places, bars and nightclubs have the highest concentrations of secondhand tobacco smoke, posing a serious health risk for workers in these venues. Objective To assess exposure of bar and nightclub employees to secondhand smoke, including non-smoking and smoking employees. Methods Between 2007 and 2009, we recruited approximately 10 venues per city and up to 5 employees per venue in 24 cities in the Americas, Eastern Europe, Asia and Africa. Air nicotine concentrations were measured for 7 days in 238 venues. To evaluate personal exposure to secondhand smoke, hair nicotine concentrations were also measured for 625 non-smoking and 311 smoking employees (N=936). Results Median (interquartile range [IQR]) air nicotine concentrations were 3.5 (1.5, 8.5) µg/m3 and 0.2 (0.1, 0.7) µg/m3 in smoking and smoke-free venues, respectively. Median (IQR) hair nicotine concentrations were 6.0 (1.6, 16.0) ng/mg and 1.7 (0.5, 5.5) ng/mg in smoking and non-smoking employees, respectively. After adjustment for age, sex, education, living with a smoker, hair treatment and region, a 2-fold increase in air nicotine concentrations was associated with a 30% (95% confidence interval 23%, 38%) increase in hair nicotine concentrations in non-smoking employees and with a 10% (2%, 19%) increase in smoking employees. Conclusions Occupational exposure to secondhand smoke, assessed by air nicotine, resulted in elevated concentrations of hair nicotine among non-smoking and smoking bar and nightclub employees. The high levels of airborne nicotine found in bars and nightclubs and the contribution of this exposure to employee hair nicotine concentrations support the need for legislation measures that ensure complete protection from secondhand smoke in these venues.

To examine how adolescents' inattentive behaviour, together with parental smoking patterns, predicts smoking initiation by age 14. DESIGN, SETTINGS: A prospective, longitudinal study: baseline at ages 11-12, follow-up at age 14. A population-based sample of Finnish twins, born 1983-1987, with parents and classroom teachers as additional informants. Two groups were formed, allocating the co-twins of each family into separate groups: the study sample and a replication sample. Twin individuals (n = 4552), aged 11-12 at baseline and 14 (average 14.04 years) at follow-up. At baseline, inattentiveness was assessed with the Multidimensional Peer Nomination Inventory (MPNI, Teacher Form) and parental smoking with individual questionnaires completed by each twins' parents; at the age 14 follow-up, adolescent smoking was assessed with a self-report questionnaire. At age 14, 57% reported never having smoked, 34% had experimented with cigarettes and 9% were current smokers. Inattentiveness and parental smoking additively predicted both experimental and current smoking in adolescence. The effects were independent of each other. The risk related to inattentiveness itself is high, but in combination with the effects of parental smoking, the probability of current smoking can rise as high as 38%, compared with 5% without these two risk factors. For prevention purposes, parental commitment to non-smoking should be emphasized.

Objectives To analyse trends in smoking prevalence in Ukraine from three surveys conducted in 2001–5, and to explore correlates of observed changes, in order to estimate the stage of tobacco epidemic in Ukraine. Design Repeated national interview surveys in Ukraine in 2001, 2002 and 2005. Main outcome measure Prevalence of current smoking among the population aged ⩾15 years. Results The age‐standardised prevalence of current smoking in Ukrainian men was 54.8% in 2001 and 66.8% in 2005. Among Ukrainian women, prevalence increased from 11.5% in 2001 to 20.0% in 2005. ORs for yearly increase in prevalence were estimated as 1.164 (95% CI 1.111 to 1.220) for men and 1.187 (1.124 to 1.253) for women, which implies that, on average, 3–4% of men and 1.5–2% of women living in Ukraine join the smoking population each year. Conclusions In Ukraine, smoking prevalence is increasing in most population groups. Among men, the medium deprivation group with secondary education has the highest smoking prevalence. Among women, while the most educated, young and those living in larger cities are the leading group for tobacco use, other groups are also increasing their tobacco use. Tobacco promotion efforts appear to have been significantly more effective in Ukraine than smoking control efforts. The decrease in real cigarette prices in Ukraine in 2001–5 could be the main factor explaining the recent growth in smoking prevalence. PMID:17565141

Aims Smoking can increase the risk of macular degeneration and this is more than additive if a person also has a genetic risk. The purpose of this study was to examine whether knowledge of genetic risk for age-related macular degeneration (AMD) could influence motivation to quit smoking. Methods A questionnaire-based study of hypothetical case scenarios given to 49 smokers without AMD. Participants were randomly allocated to a generic risk, high genetic risk, or low genetic risk of developing AMD scenario. Results Forty-seven percent knew of the link between smoking and eye disease. In all, 76%, 67%, and 46% for the high risk, generic, and low risk groups, respectively, would rethink quitting (Pfor trend=0.082). In all, 67%, 40%, and 38.5%, respectively, would be likely, very likely, or would definitely quit in the following month (Pfor trend=0.023). Few participants (<16% of any group) were very likely to or would definitely attend a quit smoking session with no difference across groups. In all, 75.5% of participants would consider taking a genetic test for AMD. Conclusion In this pilot study, a trend was seen for the group given high genetic risk information to be more likely to quit than the generic or low genetic risk groups. Participants were willing to take a genetic test but further work is needed to address the cost benefits of routine genetic testing for risk of AMD. More generic risk information should be given to the public, and health warnings on cigarette packets that ‘smoking causes blindness' is a good way to achieve this. PMID:22037055

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.

Smoking in movies: impact on adolescent smoking.

PubMed

Sargent, James D

2005-06-01

This article examines the evidence that supports an association between seeing smoking depictions in movies and adolescent smoking. The portrayal of tobacco use is common in movies and often is modeled by stars, who, from a social influences standpoint, should be powerful behavior change agents. The results of studies that assess audience responses to tobacco portrayal in movies are remarkably consistent in showing a moderate to strong association between seeing movie smoking and more positive attitudes toward smoking and adolescent smoking initiation. The two published longitudinal studies show an independent link between exposure to movie smoking at baseline and initiation in the future, with estimates of the effect size being remarkably consistent with their cross-sectional counterparts. Pediatricians should support public health campaigns to pressure the movie industry to voluntarily reduce smoking in movies and encourage parents to adhere to the Motion Picture Ratings System to reduce adolescent exposure to this powerful social influence to smoke.

Background and Purpose . The association between smoking and CV has been proved; however smoking is still the first preventable cause of death in the EU. We aim to evaluate the potential impact of the smoke ban on the number of ACS events in the Portuguese population. In addition, we evaluate the longitudinal effects of the smoking ban several years after its implementation. Methods . We analyzed the admission rate for ACS before and after the ban using data from hospital admission. Monthly crude rate was computed, using the Portuguese population as the denominator. Data concerning the proportion of smokers among ACS patients were obtained from the NRACS. Interrupted time series were used to assess changes over time. Results . A decline of -5.8% was found for ACS crude rate after the smoking ban. The decreasing trend was observed even after years since the law. The effect of the ban was higher in men and for people over 65 years. The most significant reduction of ACS rate was found in Lisbon. Conclusions . Our results suggest that smoking ban is related to a decline in ACS admissions, supporting the importance of smoke legislation as a public health measure, contributing to the reduction of ACS rate.

2012-01-01

Introduction: Although differing levels of family influences may explain some of the varying racial/ethnic trends in adolescent smoking behavior, clarification of which influences are protective against smoking may aid in the development of future ethnic-specific smoking prevention interventions. We sought to identify and compare the association of family influences on adolescent smoking among Black, Hispanic, and White adolescents in a cross-sectional national sample. Methods: Data from 6,426 parent–child dyads from Round 1 of the National Survey of Parents and Youth were analyzed. The association of family influences with ever-smokers and recent smokers was evaluated. Multinomial logistic regression using SUDAAN software was used. Results: While all measures of family influences except for parent–adolescent activities and intention to monitor were significantly protective against recent smoking and ever smoking among Whites, ethnic-specific family influence predictors of smoking were found in Blacks and Hispanics. Higher parental monitoring, higher intention to monitor, and higher connectedness were protective among Hispanics, while higher parental punishment and favorable attitude toward monitoring were protective against smoking among Blacks. For family influences significantly associated with protection against smoking, consistently greater protection was afforded against recent smoking than against ever smoking. Conclusions: Higher levels of family influences are protective against smoking among all racial/ethnic groups. There are consistencies in family influences on youth smoking; however, there may be specific family influences that should be differentially emphasized within racial/ethnic groups in order to protect against smoking behavior. Our results offer insight for designing strategies for preventing smoking in youth of different racial/ethnic backgrounds. PMID:22180584

The health risks associated with second hand smoke (SHS) are well-known. However, little is known about exposure to SHS in cars and risk of smoking uptake. This paper investigates the association between pre-adolescents reported exposure to smoking in cars and prevalence of early stage smoking activity. Data from Keeping Kids Smokefree baseline surveys of students were used to investigate smoking status and reported exposure to smoking in cars. Log binomial regression analyses were used to investigate if reported exposure to SHS in cars was associated with smoking prevalence. 83% of 5676 students invited took part. After controlling for all variables reported exposure to smoking in cars and homes were significantly associated with increased risk of initiated smoking (RR 1.87, 95% CI 1.43-2.44, and RR 1.5, 95% CI 1.13-1.97, respectively). Exposure to smoking in cars was substantially and significantly associated with risk of current smoking (RR 3.21, 95% CI 1.45-7.08). Early smoking uptake is associated with students' reported exposure to smoking in cars which confirms the importance of protecting children from SHS. Smoking in cars is under parental control and therefore modifiable. Moreover, children's reports of SHlS exposure offer a simple way of identifying families who can be targeted for tobacco control interventions. Copyright © 2011 Elsevier Ltd. All rights reserved.

Smoking is considered the single most important preventable cause of morbidity and mortality worldwide, contributing to increased incidence and severity of disabling conditions. The aim of this study was to assess the contribution of chronic conditions to the disability burden across smoking categories in middle-aged adults in Belgium. Data from 10,224 individuals aged 40 to 60 years who participated in the 1997, 2001, 2004, or 2008 Health Interview Surveys in Belgium were used. Smoking status was defined as never, former (cessation ≥2 years), former (cessation <2 years), occasional light (<20 cigarettes/day), daily light, and daily heavy (≥20 cigarettes/day). To attribute disability to chronic conditions, binomial additive hazards models were fitted separately for each smoking category adjusted for gender, except for former (cessation <2 years) and occasional light smokers due to the small sample size. An increasing trend in the disability prevalence was observed across smoking categories in men (never = 4.8%, former (cessation ≥2 years) = 5.8%, daily light = 7.8%, daily heavy = 10.7%) and women (never = 7.6%, former (cessation ≥2 years) = 8.0%, daily light = 10.2%, daily heavy = 12.0%). Musculoskeletal conditions showed a substantial contribution to the disability burden in men and women across all smoking categories. Other important contributors were depression and cardiovascular diseases in never smokers; depression, chronic respiratory diseases, and diabetes in former smokers (cessation ≥2 years); chronic respiratory diseases, cancer, and cardiovascular diseases in daily light smokers; cardiovascular diseases and chronic respiratory diseases in men and depression and diabetes in women daily heavy smokers. Beyond the well-known effect of smoking on mortality, our findings showed an increasing trend of the disability prevalence and different contributors to the disability burden across smoking categories.

On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments.

The estimated prevalence of smoking and proportion of deaths due to tobacco in Eastern European countries are among the highest in the world. Existing estimates of mortality attributable to smoking in the region are mostly indirect. The aim of this analysis was to calculate the proportion of tobacco-attributed deaths in three Eastern European countries using individual level cohort data. The PrivMort project established a cohort of relatives of participants in population sample surveys in Russia, Belarus and Hungary. Survey participants provided data on smoking habits and vital statistics of their close relatives between 1982 and 2013. Population attributable risk fractions (PARF) in men (n = 99528) and women (n = 77848) aged 40-79 years were calculated from the prevalence rates of smoking and hazard ratios of mortality for smokers versus non-smokers. Trends in PARF over four 8-year time periods (1982-1989, 1990-1997, 1998-2005, and 2006-2013) were examined. In men in the most recent period (2006-2013), the proportions of deaths attributable to tobacco were 23% in Russia, 22% in Belarus, and 22% in Hungary. The respective estimates in women were lower (2%, 2%, and 13%), possibly due to underestimation of smoking prevalence. PARF estimates have declined slightly since the early 1990s in men but increased in women. Consistently with existing indirect estimates, our results based on individual level cohort data suggest that over one fifth of all deaths in men aged 40-79 years are attributable to tobacco. While these proportions are lower in women, the increasing trend is a major concern. This is the first large scale, individual-level cohort study that estimated the mortality attributable to tobacco smoking directly in Eastern European population samples. The results confirm previous indirect estimates and show that more than 20% of all deaths in Eastern European men can be attributed to tobacco. The study also confirms the increasing trend in smoking-related deaths

Waterpipe tobacco smoking is a global health concern. Laboratory research has focused on individual waterpipe users while group use is common. This study examined user toxicant exposure and smoke toxicant yield associated with individual and group waterpipe smoking. Twenty-two pairs of waterpipe smokers used a waterpipe individually and as a dyad. Before and after smoking, blood was sampled and expired carbon monoxide (CO) measured; puff topography was recorded throughout. One participant from each pair was selected randomly and their plasma nicotine and expired air CO concentrations were compared when smoking alone to when smoking as part of a dyad. Recorded puff topography was used to machine-produce smoke that was analyzed for toxicant content. There was no difference in mean plasma nicotine concentration when an individual smoked as part of a dyad (mean = 14.9 ng/ml; standard error of the mean [SEM] = 3.0) compared to when smoking alone (mean = 10.0 ng/ml; SEM = 1.5). An individual smoking as part of as a dyad had, on average, lower CO (mean = 15.8 ppm; SEM = 2.0) compared to when smoking alone (mean= 21.3 ppm; SEM = 2.7). When two participants smoked as a dyad they took, on average, more puffs (mean = 109.8; SEM = 7.6) than a singleton smoker (mean = 77.7; SEM = 8.1) and a shorter interpuff interval (IPI; dyad mean = 23.8 seconds; SEM = 1.9; singleton mean = 40.8 seconds; SEM = 4.8). Higher concentrations of several toxicants were observed in dyad-produced smoke. Dyad smoking may increase smoke toxicant content, likely due to the dyad's shorter IPIs and greater puff number. More work is needed to understand if group waterpipe smoking alters the health risks of waterpipe tobacco smoking. This study is the first to measure toxicants in smoke generated from a waterpipe when used by a dyad. Relative to smoke generated by a singleton, dyad smoke had higher concentration of some toxicants. These differences may be attributed to differences in puffing behavior

To review the published survey data on public support for smoke-free outdoor regulations in the USA and Canada (two countries at the forefront of such policies). We searched for English language articles and reports using Medline, Google Scholar and Google for the period to December 2014. We retained population-based surveys of the adult general population in jurisdictions in the USA and Canada, with a minimum survey sample of 500. The analysis focused on assessing levels and trends in public support for different types of places and also explored how support varied between population groups. Relevant data were found from 89 cross-sectional surveys between 1993 and 2014. Support for smoke-free regulations in outdoor places tended to be highest for smoke-free school grounds (range: 57-95%) playgrounds (89-91%), and building entrances (45-89%) and lowest for smoke-free outdoor workplaces (12-46%) and sidewalks (31-49%). Support was lower among smokers, though for some types of places there was majority smoker support (eg, school grounds with at least 77% support in US state surveys after 2004). Trend data involving the same questions and the same surveyed populations suggested increased general public and smoker support for smoke-free regulations over time (eg, from 67% to 78% during 2002-2008 for smoke-free school grounds in the USA). Higher support was typically seen from women and some ethnic groups (eg, African-Americans). Outdoor smoke-free regulations can achieve majority public support, including from smokers.

Smoking habits and smoking cessation among North Carolina nurses.

PubMed

Swenson, I E

1989-01-01

A 1987 questionnaire survey of a 1% random sample (n = 356) of registered nurses in North Carolina provided data on the smoking habits and smoking cessation. Fifty-six percent were never smokers; 19% were current smokers. Among the ever smokers, 31% had quit smoking for at least one year. Twenty-two percent of the former smokers had smoked less than 5 years and 39% less than 10 years before quitting. Anecdotal notes from never smokers suggested that their major deterrent to smoking was their own parents smoking. Concerns about the addictive smoking behavior and health effects of smoking observed in their parents as well as concerns about potential health risks to themselves deterred them from smoking. Concerns about the adverse consequences of smoking was the most influential factor influencing smoking cessation and reduction of cigarette smoking. Friends' and family's encouragement to stop smoking was the most influential external factor motivating nurses to quit or reduce cigarette consumption. Fifty-seven percent of the former smokers quit smoking after one or two attempts while 53 of the current smokers had tried to quit 3 or more times - 90% had tried at least once to quit smoking; however, only 18% of the current smokers had abstained for more than one year during any of their attempts to quit. Implications of the results include: (1) smoking cessation programs for nurses in the workplace may have considerable impact since the majority of nurses who smoke are tying to quit; (2) relapse prevention strategies need to be an integral part of such smoking cessation programs including involvement of family and friends to support the smokers in their cessation efforts.

Movie smoking and urge to smoke among adult smokers.

Few studies have assessed the association between exposure to movie smoking and urge to smoke under real-world conditions. We conducted exit interviews with 4,073 movie patrons, of whom 2,817 were aged 18 years or older. Some 536 were smokers and had complete data. Subjects had exited 26 movies, of which 12 contained smoking. We used least squares regression to assess the association between exposure to movie smoking and urge to smoke (scale range 0-10), controlling for movie rating, age, sex, heaviness of smoking index (HSI, range 0-6), and time since last cigarette smoked. Median age was 27 years and 52% were female. Median urge to smoke level at movie exit was 7. The dose-response between higher categories of movie smoking and median urge to smoke was one point for two lower categories (1-11 and 11-54 s) and two for the highest category (>or=55 s), but these differences were not statistically significant. In the multivariate analysis, attendance of a movie with smoking was associated with a 0.81-point increase (95% CI = 0.46-1.16) in urge to smoke. For comparison, an HSI score of 3 (vs. 0) was associated with a 2-point increase in urge to smoke. In this sample of adult smokers, exposure to movie smoking was associated with higher urge to smoke after the movie, independent of movie rating. The effect size was consistent with responses seen in cue reactivity experiments. Exposure to movie smoking may affect urge to smoke among adult smokers.

Laboratory studies of refractory metal oxide smokes

Studies of the properties of refractory metal oxide smokes condensed from a gas containing various combinations of SiH4, Fe(CO)5, Al(CH3)3, TiCl4, O2 and N2O in a hydrogen carrier stream at 500 K greater than T greater than 1500 K were performed. Ultraviolet, visible and infrared spectra of pure, amorphous SiO(x), FeO(x), AlO(x) and TiO(x) smokes are discussed, as well as the spectra of various co-condensed amorphous oxides, such as FE(x)SiO(y) or Fe(x)AlO(y). Preliminary studies of the changes induced in the infrared spectra of iron-containing oxide smokes by vacuum thermal annealing suggest that such materials become increasingly opaque in the near infrared with increased processing: hydration may have the opposite effect. More work on the processing of these materials is required to confirm such a trend: this work is currently in progress. Preliminary studies of the ultraviolet spectra of amorphous Si2O3 and MgSiO(x) smokes revealed no interesting features in the region from 200 to 300 nm. Studies of the ultraviolet spectra of both amorphous, hydrated and annealed SiO(x), TiO(x), AlO(x) and FeO(x) smokes are currently in progress. Finally, data on the oxygen isotopic composition of the smokes produced in the experiments are presented, which indicate that the oxygen becomes isotopically fractionated during grain condensation. Oxygen in the grains is as much as 3 percent per amu lighter than the oxygen in the original gas stream. The authors are currently conducting experiments to understand the mechanism by which fractionation occurs.

Becoming a smoker usually starts during adolescence and is a dynamic process involving experimentation before the establishment of daily smoking. It has been suggested that adolescents who smoke differ from those who do not in their attitudes to smoking. The purpose of this study was to find out whether attitudes related to smoking legislation and restrictions, social pressures in smoking and image of smokers are associated with smoking experimentation, daily smoking and best friends' smoking. The data were gathered with a self-administered questionnaire in North Karelia, Eastern Finland and in the Pitkyaranta district, Republic of Karelia, Russia. The respondents were 15-year-old 9th grade pupils in local schools. In Pitkyaranta, the data analyses covered pupils in all eight schools in the area (n = 179). In North Karelia, the data analyses comprised of selected eight schools (n = 601). Data were analysed with exploratory factor analysis. The models revealed that attitudes related to restrictions and social pressure were significantly associated with experimenting with smoking [OR (95 % CI) 7.923 (5.787-10.847)], daily smoking [OR (95 % CI) 9.575 (6.727-13.628)] and the likelihood of best friends' smoking [OR (95 % CI) 3.154 (2.579-3.858)]. The stronger the young peoples' attitudes and opinions, for example, towards restrictions and with more difficulties in refusing smoking, the higher the likelihood for smoking experimentations, daily smoking as well as the likelihood for their best friends' smoking. The country and factor interactions were not associated with smoking experimentations, daily smoking or best friends' smoking. Regardless of cultural background, adolescents who smoke have more positive attitudes to smoking, and perceive more social support for smoking, than do adolescents who do not smoke. The study stresses the similarity of the results in both Karelia's despite the enormous differences in culture, economy and public policy.

Effects of the economic crisis on smoking prevalence and number of smokers in the USA.

Scanty and controversial information is available on the impact of macroeconomic fluctuations on smoking behaviour. No study has quantified the effects of fiscal crises on smoking prevalence. This study aimed to investigate the effects of the 2007-2008 economic crisis on smoking prevalence and number of smokers in the USA. Using data from the repeated Behavioural Risk Factor Surveillance System (BRFSS) surveys in pre-crisis (2005-2007) and post-crisis (2009-2010) periods on a total of 1,981,607 US adults, we separated the expected (after allowance for the demographic growth of the US population, secular smoking prevalence trends and changes in sociodemographic characteristics) from the unexpected (assumed attributable to the economic crisis) changes in the number of smokers across different employment statuses. Joinpoint regression analysis revealed no significant changes in smoking prevalence trends over the period 2005-2010. The crisis resulted in an increase in the number of smokers in the US by 0.6 million. This is largely due to an unexpected decrease of 1.7 million smokers among employed and an increase of 2.4 million smokers among unemployed individuals, whose smoking prevalence also remains extremely high in the post-crisis period (32.6%). The 2008 financial crisis had a weak effect on smoking prevalence. The pro-cyclical relationship (ie, the crisis results in a lower number of smokers) found among the employed is offset by the counter-cyclical relationship (ie, the crisis results in a higher number of smokers) found among unemployed individuals. Public health interventions should specifically target those in unemployment, particularly in hard times. Published by the BMJ Publishing Group Limited.

Background Parental smoking and exposure of the mother or the child to environmental tobacco smoke (ETS) as risk factors for Acute non-Lymphocytic Leukemia (AnLL) were investigated. Methods Incident cases of childhood AnLL were enrolled in 14 Italian Regions during 1998–2001. We estimated odds ratios (OR) and 95% confidence intervals (95%CI) conducting logistic regression models including 82 cases of AnLL and 1,044 controls. Inverse probability weighting was applied adjusting for: age; sex; provenience; birth order; birth weight; breastfeeding; parental educational level age, birth year, and occupational exposure to benzene. Results Paternal smoke in the conception period was associated with AnLL (OR for ≥11 cigarettes/day  = 1.79, 95% CI 1.01–3.15; P trend 0.05). An apparent effect modification by maternal age was identified: only children of mothers aged below 30 presented increased risks. We found weak statistical evidence of an association of AnLL with maternal exposure to ETS (OR for exposure>3 hours/day  = 1.85, 95%CI 0.97–3.52; P trend 0.07). No association was observed between AnLL and either maternal smoking during pregnancy or child exposure to ETS. Conclusions This study is consistent with the hypothesis that paternal smoke is associated with AnLL. We observed statistical evidence of an association between maternal exposure to ETS and AnLL, but believe bias might have inflated our estimates. PMID:25401754

We explored the role of rejection of parental smoking in the association between parental smoking and smoking in adolescents. In 2010-11 cross-sectional survey, 61,810 Hong Kong secondary school students (mean age 14.6 years, 50.5% boys) reported their smoking (never, not susceptible; never, susceptible; ever, not current; current), paternal and maternal smoking, and whether they accepted paternal and maternal smoking (acceptance/rejection). We used multinomial logistic regression to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of students' smoking in relation to acceptance and rejection of parental smoking, compared with no parental smoking. The OR (95% CI) of "never, susceptible", "ever, not current", and "current", compared with "never, not susceptible", in relation to acceptance of paternal smoking was 1.81 (1.67-1.96), 2.46 (2.25-2.69), and 2.79 (2.51-3.10), respectively. The corresponding ORs for rejection were 0.70 (0.64-0.76), 1.23 (1.13-1.35), and 0.47 (0.40-0.56). The OR (95% CI) of "never, susceptible", "ever, not current", and "current", compared with "never, not susceptible", in relation to acceptance of maternal smoking was 2.05 (1.80-2.33), 2.57 (2.29-2.88), and 6.33 (5.39-7.44), respectively. The corresponding ORs for rejection were 0.85 (0.69-1.05), 1.59 (1.39-1.81), and 2.14 (1.71-2.68). No overlapping was observed between the 95% CIs for acceptance and rejection of paternal or maternal smoking. While adolescent smoking was associated with parental smoking, especially in those who accepted parental smoking, the association was attenuated or reversed in those who rejected parental smoking.

Indirectly estimated absolute lung cancer mortality rates by smoking status and histological type based on a systematic review

PubMed Central

2013-01-01

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

Education and indoor smoking among parents who smoke: the mediating role of perceived social norms of smoking.

Parents with less formal education are more likely to smoke indoors, causing socioeconomic disparity in children's exposure to second-hand smoke. However, little is known about the roles of social factors in the socioeconomic gradients of indoor smoking. We tested the potential mediating role of perceived smoking norms on the associations between education and indoor smoking among parents who smoke. In this cross-sectional study, 822 smoking fathers and 823 smoking mothers, who lived with young children and were members of a Japanese online survey panel, participated. Structural equation modelling tested the mediating effects of perceived descriptive and subjective norms on the association between education and indoor smoking. Perceived pro-smoking norms, which were more prevalent among less-educated parents, mediated the association between education and indoor smoking. Household smoking status and worksite smoking ban also mediated this association via perceived norms, but only for fathers. Perceived descriptive norms explained 28.5% of the association for fathers and 37.6% for mothers; the corresponding percentages for perceived subjective norms were 9.8% and 26.6%, respectively. Perceived smoking norms, household smoking status, and a worksite smoking ban could be vital targets of a strategy aimed at reducing the socioeconomic disparity in parental home smoking behaviours.

To examine the associations of perceived interparental relationship, family harmony and family happiness with smoking intention in never-smoking Chinese children and adolescents in Hong Kong. Cross-sectional surveys of 15 753 primary (grades 4-6) and 38 398 secondary (grades 7-12) never-smoking students from 71 to 75 randomly selected primary and secondary schools in Hong Kong, 2012-2013. Outcome variable was smoking intention which denoted any affirmative response to smoke within the coming year or when a cigarette was offered by a good friend. Exposure variables were perceived interparental relationship and family harmony each measured on a five-point scale from 'very good' to 'very bad' and perceived family happiness on a four-point scale from 'very happy' to 'not happy at all'. Potential confounders included age, sex, family structure, perceived family affluence, parental smoking and sibling smoking. In primary students, the adjusted ORs (AORs) (95% CI) of smoking intention generally increased with more negative perception of the family relationship: up to 3.67 (1.91 to 7.05) for interparental relationship, 7.71 (4.38 to 13.6) for family harmony and 5.40 (3.41 to 8.55) for family happiness. For secondary students, the corresponding AORs (95% CI) were 2.15 (1.64 to 2.82) for interparental relationship, 2.98 (2.31 to 3.84) for family harmony and 2.61 (1.80 to 3.79) for family happiness. All p for trend <0.001. More negatively perceived interparental relationship, family harmony and family happiness were associated with higher odds of smoking intention with dose-response relationships in never-smoking Chinese children and adolescents in Hong Kong. Children's perception of their family relationship may be an important intervening point for preventing youth from initiating smoking. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

In the Philippines, smoking is highly prevalent and tobacco control policies fail to fully implement the WHO Framework Convention on Tobacco Control provisions. To aid in policy change, intervention implementation, monitoring and evaluation, this study aimed to provide the first internally consistent and latest Philippine estimates of the following: disability-adjusted life-years (DALYs) lost due to lung cancer; population-attributable fractions (PAFs) of smoking; and smoking-attributable lung cancer DALYs. This study applied the Global Burden of Disease and Comparative Risk Assessment frameworks to secondary data, supplemented by expert opinion. A comprehensive internally consistent assessment of disease epidemiology was conducted using DISMOD II and disease impact was quantified as DALYs. PAFs were calculated using the smoking impact ratio and Monte Carlo uncertainty analyses were conducted. For 2008, lung cancer incidence and mortality estimates were 10 871 cases and 9871 deaths respectively. Lung cancer accounted for an estimated 267 787 DALYs lost, 99% of which were due to years of life lost. Overall, the PAF of smoking was 65% and a total of 173 103 DALYs were smoking-attributable. There were increasing trends in incidence, mortality and DALY rates with age. The majority of incidence (72%), mortality (71%) and disease burden (72%) occurred among men, who also had higher PAF estimates. Considerable health gains could be achieved if smoking exposure were reduced in the Philippines. Strong enforcement of measures like increasing taxation to the WHO-endorsed rate, expanding smoke-free environments, and requiring large graphic warnings within a comprehensive tobacco control programme is recommended.

2010-01-01

Background The National Cancer Institute has concluded that exposure to smoking in movies causes adolescent smoking and there are similar results for young adults. Purpose This study investigated whether exposure of young adult smokers to images of smoking in films stimulated smoking behavior. Methods 100 cigarette smokers aged 18–25 years were randomly assigned to watch a movie montage composed with or without smoking scenes and paraphernalia followed by a10-minute recess. The outcome was whether or not participants smoked during the recess. Data were collected and analyzed in 2008 and 2009. Results Smokers who watched the smoking scenes were more likely to smoke during the break (OR3.06, 95% CI=1.01, 9.29). In addition to this acute effect of exposure, smokers who had seen more smoking in movies before the day of the experiment were more likely to smoke during the break (OR 6.73; 1.00–45.25 comparing the top to bottom percentiles of exposure) were more likely to smoke during the break. Level of nicotine dependence (OR 1.71; 1.27–2.32 per point on the FTND scale), “contemplation” (OR 9.07; 1.71–47.99) and “precontemplation” (OR 7.30; 1.39–38.36) stages of change, and impulsivity (OR 1.21; 1.03–1.43), were also associated with smoking during the break. Participants who watched the montage with smoking scenes and those with a higher level of nicotine dependence were also more likely to have smoked within 30 minutes after the study. Conclusions There is a direct link between viewing smoking scenes and immediate subsequent smoking behavior. This finding suggests that individuals attempting to limit or quit smoking should be advised to refrain from or reduce their exposure to movies that contain smoking. PMID:20307802

This study compared the immediate effects of smoking on cardiorespiratory responses to dynamic arm and leg exercises. This randomized crossover study recruited 14 college students. Each participant underwent two sets of arm-cranking (AC) and leg-cycling (LC) exercise tests. The testing sequences of the control trial (participants refrained from smoking for 8 h before testing) and the experimental trial (participants smoked two cigarettes immediately before testing) were randomly chosen. We observed immediate changes in pulmonary function and heart rate variability after smoking and before the exercise test. The participants then underwent graded exercise tests of their arms and legs until reaching exhaustion. We compared the peak work achieved and time to exhaustion during the exercise tests with various cardiorespiratory indices [i.e., heart rate, oxygen consumption (VO2), minute ventilation (VE)]. The differences between the smoking and control trials were calculated using paired t-tests. For the exercise test periods, VO2, heart rate, and VE values were calculated at every 10% increment of the maximal effort time. The main effects of the time and trial, as well as their trial-by-time (4 × 10) interaction effects on the outcome measures, were investigated using repeated measure ANOVA with trend analysis. 5 min after smoking, the participants exhibited reduced forced vital capacities and forced expiratory volumes in the first second (P < 0.05), in addition to elevated resting heart rates (P < 0.001). The high-frequency, low-frequency, and the total power of the heart rate variability were also reduced (P < 0.05) at rest. For the exercise test periods, smoking reduced the time to exhaustion (P = 0.005) and the ventilatory threshold (P < 0.05) in the LC tests, whereas no significant effects were observed in the AC tests. A trend analysis revealed a significant trial-by-time interaction effect for heart rate, VO2, and VE during the graded exercise test (all P < 0

To develop more effective anti-smoking programs, it is important to understand the factors that influence people to smoke. Guided by attribution theory, a longitudinal study was conducted to investigate how individuals' cognitive attributions for smoking were associated with subsequent smoking development and through which pathways. Middle and high school students in seven large cities in China (N=12,382; 48.5% boys and 51.5% girls) completed two annual surveys. Associations between cognitive attributions for smoking and subsequent smoking initiation and progression were tested with multilevel analysis, taking into account plausible moderation effects of gender and baseline smoking status. Mediation effects of susceptibility to smoking were investigated using statistical mediation analysis (MacKinnon, 2008). Six out of eight tested themes of cognitive attributions were associated with subsequent smoking development. Curiosity (β=0.11, p<0.001) and autonomy (β=0.08, p=0.019) were associated with smoking initiation among baseline non-smokers. Coping (β=0.07, p<0.001) and social image (β=0.10, p=<.0001) were associated with smoking progression among baseline lifetime smokers. Social image (β=0.05, p=0.043), engagement (β=0.07, p=0.003), and mental enhancement (β=0.15, p<0.001) were associated with smoking progression among baseline past 30-day smokers. More attributions were associated with smoking development among males than among females. Susceptibility to smoking partially mediated most of the associations, with the proportion of mediated effects ranging from 4.3% to 30.8%. This study identifies the roles that cognitive attributions for smoking play in subsequent smoking development. These attributions could be addressed in smoking prevention programs.

Introduction Few studies have assessed the association between exposure to movie smoking and urge to smoke under real-world conditions. Methods We conducted exit interviews with 4,073 movie patrons, of whom 2,817 were aged 18 years or older. Some 536 were smokers and had complete data. Subjects had exited 26 movies, of which 12 contained smoking. We used least squares regression to assess the association between exposure to movie smoking and urge to smoke (scale range 0–10), controlling for movie rating, age, sex, heaviness of smoking index (HSI, range 0–6), and time since last cigarette smoked. Results Median age was 27 years and 52% were female. Median urge to smoke level at movie exit was 7. The dose–response between higher categories of movie smoking and median urge to smoke was one point for two lower categories (1–11 and 11–54 s) and two for the highest category (≥55 s), but these differences were not statistically significant. In the multivariate analysis, attendance of a movie with smoking was associated with a 0.81-point increase (95% CI = 0.46–1.16) in urge to smoke. For comparison, an HSI score of 3 (vs. 0) was associated with a 2-point increase in urge to smoke. Discussion In this sample of adult smokers, exposure to movie smoking was associated with higher urge to smoke after the movie, independent of movie rating. The effect size was consistent with responses seen in cue reactivity experiments. Exposure to movie smoking may affect urge to smoke among adult smokers. PMID:19542516

The objective of this study was to investigate the effect of smoking cues in movies on immediate smoking behavior. We tested whether smokers who are confronted with smoking characters in a movie smoke more cigarettes while watching than those confronted with non-smoking characters and whether this effect is less profound when smokers are more involved in the narrative (i.e., transportation). Using an experimental design, 60 daily smokers were assigned randomly to one of two movie conditions (smoking vs. non-smoking characters). Participants were exposed to a 72-min movie clip and were allowed to smoke while watching the movie. Transportation and smoking habits were assessed with a questionnaire afterward. The results showed a significant interaction effect between movie condition and transportation on immediate smoking behavior, indicating that smokers who were less transported smoked significantly more cigarettes when they were exposed to smoking characters compared with non-smoking characters. These results call for (a) increasing the awareness among people about the effect smoking cues in movies might have and (b) stricter control over smoking cues in movies.

Summary Tobacco control policies are examined utilizing a simulation model for California, the state with the longest running comprehensive program. We assess the impact of the California Tobacco Control Program (CTCP) and surrounding price changes on smoking prevalence and smoking-attributable deaths. Modeling begins in 1988 and progresses chronologically to 2004, and considers four types of policies (taxes, mass media, clean air laws, and youth access policies) independently and as a package. The model is validated against existing smoking prevalence estimates. The difference in trends between predicted smoking rates from the model and other commonly used estimates of smoking prevalence for the overall period were generally small. The model also predicted some important changes in trend, which occurred with changes in policy. The California SimSmoke model estimates that tobacco control policies reduced smoking rates in California by an additional 25% relative to the level that they would have been if policies were kept at their 1988 level. By 2004, the model attributes over 60% of the reduction to price increases, over 25% of the overall effect to media policies, 10% to clean air laws, and only a small percent to youth access policies. The model estimates that over 5,000 lives will be saved in the year 2010 alone as a result of the CTCP and industry-initiated price increases, and that over 50,000 lives were saved over the period 1988-2010. Tobacco control policies implemented as comprehensive tobacco control strategies have significantly impacted smoking rates. Further tax increases should lead to additional lives saved, and additional policies may result in further impacts on smoking rates, and consequently on smoking-attributable health outcomes in the population.

Does Watching Smoking in Movies Promote Teenage Smoking?

PubMed Central

Heatherton, Todd F.; Sargent, James D.

2009-01-01

Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent smoking initiation is greatest among those traditionally considered at lower risk for smoking, such as those low in sensation seeking and those whose parents do not smoke. In this article, we consider possible moderators and mediators of this important media effect as well as health-policy implications. The take-home message is that eliminating smoking in movies may prevent a substantial number of adolescents from smoking. PMID:20160916

To develop insight into population-specific meanings of smoking in our highly multicultural middle schools in order to provide effective and appropriate tools for smoking prevention efforts. We used focus group interviews to develop the Meanings of Smoking Index (MSI), a nine-item scale that uses a "mark all that apply" strategy to assess what smoking means to children who have tried smoking as well as to those who are susceptible to smoking. In 24 public and parochial middle schools in the greater Los Angeles area, 2336 7th graders (1483 Latino, 565 Asian/ Pacific Islander and 288 white, 55.2% of the sample was female) completed the MSI as part of a school-based trial of culturally-targeted smoking prevention strategies. Items were rank ordered according to salience (rate of endorsement) and relevance (strength of relationship with lifetime smoking) across the entire sample and separately for Hispanic/Latino, Asian/Asian-American and white respondents. Spearman correlation coefficient was used to compare results between ethnicities. The most frequently endorsed meanings were similar across ethnicities. Magnitude of associations between smoking behaviors and meanings were dissimilar across ethnicities. The meaning with the strongest relationship to lifetime smoking for whites and Latinos was "it helps me study" (OR 3.4 and 2.6 respectively), and for Asians was "don't want to make another smoke alone" (OR 5.4). We have shown previously that interventions on meanings of eating behaviors changed dietary behaviors in adolescents. The present findings suggest that meanings are powerful determinants of adolescent smoking in culturally diverse populations and could offer powerful intervention tools to prevent adolescent smoking.

Smoking has a negative effect on most diseases, yet it is under-investigated in people with epilepsy; thus its role is not clear in the general population with epilepsy. We performed a retrospective pilot study on males with epilepsy to determine the smoking rate and its relationship with seizure control using univariate analysis to calculate odds ratios (ORs) and also used a multi-variate logistic regression model. The smoking rate in our sample of 278 individuals was 25.5%, which is lower than the general Chinese population smoking rate among males of 52.1%. We used two classifications: the first classified epilepsy as generalized, or by presumed topographic origin (temporal, frontal, parietal and occipital). The second classified the dominant seizure type of an individual as generalized tonic clonic seizure (GTCS), myoclonic seizure (MS), complex partial seizure (CPS), simple partial seizure (SPS), and secondary GTCS (sGTCS). The univariable analysis of satisfactory seizure control profile and smoking rate in both classifications showed a trend towards a beneficial effect of smoking although most were not statistically significant. Considering medication is an important confounding factor that would largely influence seizure control, we also conducted multi-variable analysis for both classifications with drug numbers and dosage. The result of our model also suggested that smoking is a protective factor. Our findings seem to suggest that smoking could have a potential role in seizure control although confounders need exploration particularly in view of the potential long term health effects. Replication in a much larger sample is needed as well as case control studies to elucidate this issue. Copyright © 2017 Elsevier Inc. All rights reserved.

We evaluated the associations of smoking, alcohol consumption, and physical activity with sex steroid hormone concentrations among 1,275 men > or =20 years old who participated in the Third National Health and Nutrition Examination Survey (NHANES III). Serum concentrations of testosterone, estradiol, and sex hormone-binding globulin (SHBG) were measured. We compared geometric mean concentrations across levels of smoking, alcohol, and physical activity using multiple linear regression. Current smokers had higher total testosterone (5.42, 5.10, and 5.26 ng/ml in current, former, and never smokers), free testosterone (0.110, 0.102, and 0.104 ng/ml), total estradiol (40.0, 34.5, and 33.5 pg/ml), and free estradiol (1.05, 0.88, and 0.84 pg/ml) compared with former and never smokers (all p < or = 0.05). Men who consumed > or =1 drink/day had lower SHBG than men who drank less frequently (31.5 vs. 34.8 nmol/l, p = 0.01); total (p-trend = 0.08) and free testosterone (p-trend = 0.06) increased with number of drinks per day. Physical activity was positively associated with total (p-trend = 0.01) and free testosterone (p-trend = 0.05). In this nationally representative sample of men, smoking, alcohol, and physical activity were associated with hormones and SHBG, thus these factors should be considered as possible confounders or upstream variables in studies of hormones and men's health, including prostate cancer.

Causes of the Decline in Cigarette Smoking Among African American Youths From the 1970s to the 1990s

Adult cigarette smoking prevalence trends among African Americans (AAs) and Whites are similar. However, during the decline in youth smoking that occurred between the mid-1970s and the early 1990s, the drop in smoking rates among AA adolescents was more than double that among Whites. We examined the evidence for potential explanations for this phenomenon. On the basis of our findings, we propose that racial differences in parental attitudes, religious ties, negative perceptions and experiences of the health effects of smoking, worsening poverty, increased use of food stamps, and price sensitivity were major factors contributing to the more rapid decrease in and continued lower rates of smoking among AA youths.

Tobacco smoking is common among various social groups. There is still high prevalence of smoking among health care professionals. The aim of the study was to assess knowledge about smoke-free law in public places in Poland among smoking and nonsmoking students of selected medical university. We surveyed 50 students of one medical university aged 23 +/- 2 years. Control group consisted with 61 students of other universities located in the same region aged 23 +/- 3 years. We developed a new survey to assess students knowledge about smoke-free regulations and their implementations in various public places. Smoking status was verified with exhaled carbon monoxide levels (COex). 57% off all surveyed students declared being familiar with smoke-free law. However, we detected a significant difference between the knowledge of medical vs. nonmedical students (76% vs. 41%, p < 0.05). The knowledge about smoke-free law in Poland among students is not sufficient, especially among nonmedical students.

Few studies have investigated the complex interactions among the individual- and community-level social risk factors that underlie adolescents’ smoking behaviors. This study investigated whether community-level adult daily smoking prevalence is associated with adolescents’ smoking and whether it moderates the associations between perceived friends’ smoking approval and smoking behavior and adolescents’ own smoking. Self-reported data from 1,190 youths (50.3% female; 13–18 years old) in 50 midsized Californian cities were obtained through telephone interviews. Community characteristics were obtained from 2010 GeoLytics data. Community adult daily smoking prevalence was ascertained from telephone interviews with 8,918 adults conducted in the same 50 cities. Multilevel analyses, controlling for individual and city characteristics, were used to predict adolescents’ past 12-month smoking from perceived friends’ smoking approval and smoking behavior and from community adult daily smoking prevalence. Results showed that perceived friends’ smoking approval and behavior were associated positively with adolescents’ smoking, as was the community-level prevalence of adult daily smoking. Furthermore, the association between perceived friends’ smoking behavior and adolescents’ own smoking was moderated by the prevalence of adult daily smokers in the community. Specifically, the association was stronger in cities with higher prevalence of adult smokers. These results suggest that adult community norms that are more supportive of smoking may enhance the influence of friends’ smoking behavior. Therefore, interventions designed to prevent or reduce youths’ smoking should also focus on reducing smoking by adults. PMID:24241785

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.

Smoking is a major contributor to all-cause mortality in Europe and accounts for one-fifth of the cancer-related deaths. Monitoring the tobacco epidemic via an analysis of lung cancer trends is essential in helping countries arrest the effects of tobacco epidemic in the region. The study aims to provide a comprehensive and up-to-date overview of the temporal patterns of lung cancer mortality in Europe, emphasizing country- and sex-specific differences. National lung cancer mortality data were extracted from the WHO mortality databank by age, sex, year of death (1970-2007) for 36 countries in Europe. Trends in lung cancer mortality in men have tended to decrease in many European countries during the last two decades, particularly in North and Western Europe. Among women, mortality rates are still increasing in many countries, although in a few populations, rates are beginning to stabilize, notably in the high-risk countries within Eastern Europe (Hungary, Poland and the Czech Republic), and in Northern Europe (Denmark, Iceland and the United Kingdom). Men and women are clearly in very different phases of the smoking epidemic, and, as reflected in the mortality rates by birth cohort, the stage varies widely by country within each European region. That lung cancer mortality trends in men are on a downwards path in most European countries while female rates continue to rise, points to an urgent need for national and European prevention strategies that target tobacco cessation and prevention among European women.

To establish baseline noninvasive carboxyhemoglobin (COHb) levels in children and determine the influence of exposure to environmental sources of carbon monoxide (CO), especially environmental tobacco smoke, on such levels. Second-hand smoking may be a risk factor for adverse outcomes following anesthesia and surgery in children (1) and may potentially be preventable. Parents and their children between the ages of 1-12 were enrolled on the day of elective surgery. The preoperative COHb levels of the children were assessed noninvasively using a CO-Oximeter (Radical-7 Rainbow SET Pulse CO-Oximeter; Masimo, Irvine, CA, USA). The parents were asked to complete an environmental air-quality questionnaire. The COHb levels were tabulated and correlated with responses to the survey in aggregate analysis. Statistical analyses were performed using the nonparametric Mann-Whitney and Kruskal-Wallis tests. P < 0.05 was statistically significant. Two hundred children with their parents were enrolled. Children exposed to parental smoking had higher COHb levels than the children of nonsmoking controls. Higher COHb values were seen in the youngest children, ages 1-2, exposed to parental cigarette smoke. However, these trends did not reach statistical significance, and confidence intervals were wide. This study revealed interesting trends of COHb levels in children presenting for anesthesia and surgery. However, the COHb levels measured in our patients were close to the error margin of the device used in our study. An expected improvement in measurement technology may allow screening children for potential pulmonary perioperative risk factors in the future.

Smoking is the single most avoidable risk factor for cancers. Majority of smokers know about this fact but it is difficult for them to give it up mainly in the face of widespread smoking advertisements by the tobacco industries. To reduce the prevalence of smoking and its associated cancers, immediate actions are required by public health authorities. Social marketing is an effective strategy to promote healthy attitudes and influence people to make real, sustained health behavior change by transiting through different stages which include precontemplation, contemplation, preparation, action, and maintenance. Social marketing can influence smokers to voluntarily accept, reject, modify, or abandon their smoking behavior. In Pakistan, the smoking prevalence has been increasing, necessitating effective measures. The trend of its usage has been going upwards and, according to the World Health Organization, in Pakistan, the usage of cigarette smoking is increased by 30% compared to 1998 figures. The Pakistan Pediatrics Association has estimated 1,000 to 1,200 school-going children between the ages of 6 and 16 years take up smoking every day. In Pakistan, ex-smokers in the low socioeconomic group reported spending 25% of the total household income on this habit. This paper focuses on the antismoking social marketing strategy in Pakistan with an aim to reduce smoking prevalence, especially among the youth.

The purpose of this study is to estimate changes in the cigarette smoking prevalence among U.S. adults with and without depression from 2005 to 2014 by income and education level and overall. This study examined data from adult respondents (aged ≥18 years) in the National Survey on Drug Use and Health, an annual cross-sectional study of U.S. individuals. Data from the years 2005 to 2014 were analyzed for a total analytic sample of n=378,733. The prevalence of past-month cigarette smoking was examined annually from 2005 to 2014 among adults with and without past-year major depression, overall and by income/education, using linear trend analyses. Data analysis occurred in 2017. The prevalence of smoking declined significantly from 2005 to 2014 among those with depression (37.62% to 34.01%; p<0.001) and without depression (23.99% to 19.87%; p<0.001). Yet, smoking remained nearly twice as common among those with depression during this period. Among adults with depression in the lowest income and education groups, the prevalence of smoking was more than double the prevalence of smoking among adults with depression in the highest income and education groups. Disparities in smoking prevalence are pronounced when depression and SES are considered simultaneously. Targeted public health and clinical efforts to reduce smoking among adult smokers of lower SES with depression are needed. Copyright © 2018 American Journal of Preventive Medicine.

Youth smoking trends among Latin American countries, including Mexico, are on the rise. Notably, although the high prevalence of smoking in teens has been well documented in the literature, few studies have evaluated the impact of smoking and secondhand smoke (SHS) exposure on their respiratory system. To investigate the effects of smoking and SHS exposure on the respiratory health and lung function among eighth-grade students in Juárez, Mexico. A cross-sectional study was undertaken on a sample of convenience. The study outcomes centered on evaluating 300 students' lung function by spirometry (forced expiratory volume in 1 second [FEV1], forced expiratory volume in 1 second/forced vital capacity ratio [FEV1/FVC], and forced mid-expiratory flow rate [FEF25%-75%]) and their respiratory health (smoking behavior and SHS exposure) by their self-reported responses to a standardized respiratory questionnaire. The study outcomes were compared among three distinct groups: 1) nonsmokers/nonexposed to SHS; 2) nonsmokers/exposed to SHS; and 3) smokers. The majority of the study participants were 14 years old (85%), females (54%), who attended eighth grade in a public school setting (56%). Approximately, half reported being of low socioeconomic status (49%) and nonsmokers/exposed to SHS (49%). The lung function parameters of smokers were found to be lower (FEV1 =62.88±10.25; FEV1/FVC =83.50±14.15; and FEF25%-75% =66.35±12.55) than those recorded for the nonsmokers/exposed to SHS (FEV1 =69.41±11.35; FEV1/FVC =88.75±15.75; and FEF25%-75% =78.90±14.65) and significantly reduced when compared to the nonsmokers/nonexposed to SHS (FEV1 =79.14±13.61; FEV1/FVC =94.88±21.88; and FEF25%-75% =87.36±17.02) (P<0.001). Similarly, respiratory complaints were more prevalent among smokers and those exposed to SHS when compared to nonsmokers/nonexposed to SHS. Our findings suggest that initiation of cigarette smoking and, to a lesser extent, exposure to SHS in adolescence leads to

The effects of marijuana smoke exposure on several measures of tobacco cigarette smoking behavior were examined. Eight healthy adult male volunteers, who smoked both tobacco and marijuana cigarettes, participated in residential studies, lasting 10 to 15 days, designed to measure the effects of marijuana smoke exposure on a range of behavioral variables. Tobacco cigarettes were available throughout the day (9:00 A.M. until midnight). Each day was divided into a private period (9:00 A.M. to 5:00 P.M.), during which subjects were socially isolated, and a social period (5:00 P.M. to midnight), during which subjects could interact. Under blind conditions, subjects smoked placebo and active marijuana cigarettes (0%, 1.3%, 2.3%, or 2.7% delta 9-tetrahydrocannabinol) four times daily (9:45 A.M., 1:30 P.M., 5:00 P.M. and 8:30 P.M.). Each subject was exposed to both placebo and one active dose over 2- to 5-consecutive-day intervals, and dose conditions (i.e., placebo or active) alternated throughout the study. Active marijuana smoking significantly decreased the number of daily tobacco smoking bouts, increased inter-bout intervals and decreased inter-puff intervals. Marijuana decreased the number of tobacco smoking bouts by delaying the initiation of tobacco cigarette smoking immediately after marijuana smoking, whereas decreases in inter-puff intervals were unrelated to the time of marijuana smoking. No consistent interactions between marijuana effects and social or private periods (i.e., time of day) were observed.

Previous studies have documented higher health risks for lesbian, gay, and bisexual youth compared to heterosexual youth. However, none has reported whether the sexual orientation-based gaps have widened, narrowed, or remained unchanged over time. The purpose of this study was to develop a way to test differences in trends between sexual minority and heterosexual youth cohorts in population-based studies, with cigarette smoking as an exemplar. We analysed the Minnesota Student Survey of 1998-2010, a repeated, cross-sectional census of adolescent health in grades 9 and 12. Our sample was students with recent sexual experience (Ns = 17,376-19,617). Sexual orientation was measured by gender of sexual partners in the past 12 months: students with only opposite-gender partner(s) (OPPOS), students with both male and female partners (BOTH), students with only same-gender partner(s) (SAME). We used logistic regressions to examine trends in prevalence of past-month cigarette smoking from 1998 to 2010, separately for each orientation group. We then applied novel interaction analyses to test whether disparities in smoking prevalence between OPPOS and SAME/BOTH changed over time. Recent smoking rates decreased over time among all orientation groups. BOTH adolescents were more likely than OPPOS adolescents to report past 30-day smoking, but there were no significant differences between SAME adolescents and OPPOS adolescents. Year-by-orientation interactions indicated the gap between BOTH adolescents and OPPOS adolescents widened from 1998 to 2004, then persisted between 2004 and 2010. No significant interaction effects were observed between SAME adolescents and OPPOS adolescents. All orientation groups had decreasing trends in recent cigarette smoking; however, disparities in smoking rates remain between heterosexual adolescents and bisexual adolescents. These results provide a new method of not just documenting trends within minority groups, but examining whether health

While active maternal tobacco smoking has well established adverse perinatal outcomes, the effects of passive maternal smoking, also called environmental tobacco exposure (ETS), are less well studied and less consistent. To determine to the effect of ETS on perinatal outcomes. Medline, EMBASE and reference lists were searched. Studies comparing ETS-exposed pregnant women with those unexposed which adequately addressed active maternal smoking. Two reviewers independently assessed titles, abstracts, full studies, extracted data and assessed quality. Dichotomous data were pooled using odds ratios (OR) and continuous data with weighted mean differences (WMD) using a random effects model. Seventy-six articles were included with a total of 48,439 ETS-exposed women and 90,918 unexposed women. ETS-exposed infants weighed less [WMD -60 g, 95% confidence interval (CI) -80 to -39 g], with a trend towards increased low birthweight (LBW, < 2,500 g; RR 1.16; 95% CI 0.99-1.36), although the duration of gestation and preterm delivery were similar (WMD 0.02 weeks, 95% CI -0.09 to 0.12 weeks and RR 1.07; 95% CI 0.93-1.22). ETS-exposed infants had longer infant lengths (1.75 cm; 95% CI 1.37-2.12 cm), increased risks of congenital anomalies (OR 1.17; 95% CI 1.03-1.34) and a trend towards smaller head circumferences (-0.11 cm; 95% CI -0.22 to 0.01 cm). ETS-exposed women have increased risks of infants with lower birthweight, congenital anomalies, longer lengths, and trends towards smaller head circumferences and LBW.

To find out the smoking status among the families and their members, in order to hold their knowledge, attitude, practice on smoking and its influence and to put forward the countermeasure of smoking Control. A questionnaire surveys were conducted among 419 people which came from 419 families. 409 qualified questionnaire were obtained. The data were analyzed by descriptive statistics, test and logistic analysis. The family current smoking rates were 68.2%, the smoking rates of past family were 90.2%, the current smoking rates of individual were 31.5%, the individual past smoking rates were 39.9%. Those who attempted smoking under the age of 18 years accounted for 46.6%. Those who smoked their first cigarette from friends accounted for 48.1%. The comparisons of knowledge, attitude between smoking-ever family members and non-smoking family members had significant difference (P < 0.05). The influences of three smoking limit in the smoking-ever family on their members had significant difference (P < 0.05). The comparisons of knowledge, attitude between smoking family members and non-smoking family members had significant difference (P < 0.05). Those who were married women, and had career had high score of KAP. The contents of education of the decreases of smoking rates were on the following: (1) Smoking damages health. (2) Smoking should not be used as means of communication. (3) Feel offensive when someone smoking around. (4) Most persons still don't smoke. The key place of smoking control could be family. Smoking control could depend on married female. The key crowd of tobacco control could be children and youngsters. Not offering smoke and not advise others to smoking could be the key measures of smoking control.

To explore whether parental behaviours related to smoking socialisation and parenting are associated with smoking susceptibility and current smoking in 14-15 year old students. Data were sourced from the New Zealand 2006 Year 10 In-depth Survey, a school-based survey of 3,189 students. Outcome measures were susceptibility to smoking and current smoking. Potential determinants were second-hand smoke exposure in the home, parental smoking, parental anti-smoking expectations, anti-smoking rules, pocket money, monitoring of pocket money expenditure, general rule setting and monitoring, and concern about education. Analysis used logistic regression to adjust for potential confounding factors. Exposure to second-hand smoke and lack of parental anti-smoking expectations were independently associated with smoking susceptibility and current smoking. Parental smoking was not independently associated with current smoking or susceptibility. Receiving pocket money and an absence of monitoring of expenditure were associated with smoking susceptibility and current smoking. Lack of parental rule setting was associated with smoking susceptibility. Findings were similar whether or not one or more parents were smokers. Not allowing smoking in the home, communicating non-smoking expectations to children, monitoring pocket money, and setting rules to guide behaviour are strategies which are likely to reduce risk of smoking uptake. The study provides evidence to inform the development of parent-focused interventions to reduce the risk of smoking initiation by children. © 2011 The Authors.

To document levels of public support in Australia for smoking restrictions in licensed premises, including trends over time, and to examine the potential effects of a ban on patronage. Systematic review of published and unpublished studies of community and staff attitudes towards smoking in bars, gaming areas and related venues were identified using Medline, Current Contents, PsycINFO and AUSTHealth prior to September 2002. State and Territory health departments, cancer organisations and branches of the National Heart Foundation were approached. Cross-sectional surveys reporting data on attitudes towards smoking restrictions and/or perceptions of effects on patronage were sought. Two reviewers assessed studies for inclusion. One extracted data using pre-coded categories with checking by the second. Thirty-four community and seven staff surveys were synthesised qualitatively, with greater emphasis given to surveys using random selection. All surveys conducted since 1993, which included the separate smoking area response option, have demonstrated majority support for some form of smoking restriction on licensed premises. From 2000, surveys with the ban option alone report majority support for prohibiting smoking completely in bars (52-68%) and gaming areas (64-76%). Support increased significantly after the Sharp damages award. Customer preference data indicate banning smoking is most likely to have a neutral or positive effect on patronage. Support for a ban on smoking in licensed premises has increased by almost 20% in the past decade. State and Territory governments should introduce legislation banning smoking in all indoor drinking and gaming areas immediately.

This study investigates the independent and combined effects of smoking of parents and best friend on smoking and the intention to initiate or quit smoking in adolescents. In this school-based survey, 6,553 Hong Kong students aged 13-18 reported their demographic characteristics, smoking status of themselves, parents, and best friend; and intention to smoke (initiation among never-smokers and reinitiation among ex-smokers) or quit smoking among current smokers. Logistic regression yielded adjusted odds ratios (AORs) of student smoking (current/ever) and intention to smoke or quit smoking for parental (paternal/maternal/both parents vs. none) and best friend (yes vs. no) smoking. Parental smoking and having a smoking best friend were associated with adolescent current smoking, ever smoking, and intention to initiate smoking. Having a smoking best friend was also associated with reinitiating and quitting smoking. The AORs (95% CI) of current smoking for having a smoking best friend, in addition to smoking father, mother, or both were 19.14 (14.36-25.51), 20.38 (12.42-33.43), and 24.18 (15.89-36.77). The respective AORs of ever smoking were 8.30 (6.74-10.22), 8.92 (5.63-14.12), and 11.99 (8.05-17.87). Parental smoking and best friend smoking have independent effects on adolescent smoking behaviors. Their combined effects on current and ever smoking were particularly large. Smoking prevention programs should pay special attention to adolescents with both best friend and parents who smoke.

Bladder cancer is common worldwide and the fourth most commonly diagnosed malignancy in men in Argentina. To describe bladder cancer mortality trends in Córdoba (1986-2006), considering the effect of age, period, and cohort, and to estimate the effect of arsenic exposure on bladder cancer, and its interaction with sex, while controlling by smoking habits and space and time variation of the rates. A joinpoint regression was performed to compute the estimated annual percentage changes (EAPC) of the age-standardized mortality rates (ASMR) in an adult population from Córdoba, Argentina. A Poisson model was fitted to estimate the effect of age, period, and cohort. The influence of gender, tobacco smoking (using lung cancer ASMR as surrogate), and arsenic in drinking water was examined using a hierarchical model. A favorable trend (1986-2006) in bladder cancer ASMR in both sexes was found: EAPC of -2.54 in men and -1.69 in women. There was a decreasing trend in relative risk (RR) for cohorts born in 1931 or after. The multilevel model showed an increasing risk for each increase in lung cancer ASMR unit (RR = 1.001) and a biological interaction between sex and arsenic exposure. RR was higher among men exposed to increasing As-exposure categories (RR male low exposure 3.14, RR male intermediate exposure 4.03, RR male high exposure 4.71 versus female low exposure). A non-random space-time distribution of the rates was observed. There has been a decreasing trend in ASMR for bladder cancer in Córdoba. This study confirms that bladder cancer is associated with age, gender, smoking habit, and exposure to arsenic. Moreover, an effect measure modification between exposure to arsenic and sex was found.

To measure changes over time in cigarette smoking uptake prevalence and timing during young adulthood (ages 19-26 years), and associations between time-invariant/-varying characteristics and uptake prevalence/timing. Discrete-time survival modeling of data collected from United States high school seniors (modal age 17/18) enrolled in successive graduating classes from 1976 to 2005 and participating in four follow-up surveys (to modal age 25/26). The longitudinal component of the Monitoring the Future study. A total of 10 758 individuals reporting no life-time smoking when first surveyed as high school seniors. Smoking uptake (any, experimental, occasional and regular); socio-demographic variables; marital, college and work status; time spent socializing. The percentage of young adults moving from non-smoker to experimental smoking [slope estimate 0.11, standard error (SE) = 0.04, P = 0.005] or occasional smoking (slope estimate 0.17, SE = 0.03, P < 0.001) increased significantly across graduating classes; the percentage moving from non-smoker to regular smoker remained stable. All forms of smoking uptake were most likely to occur at age 19/20, but uptake prevalence at older ages increased over time [e.g. cohort year predicting occasional uptake at modal age 25/26 adjusted hazard odds ratio (AHOR) = 1.05, P = 0.002]. Time-invariant/-varying characteristics had unique associations with the timing of various forms of smoking uptake (e.g. at modal age 21/22, currently attending college increased occasional uptake risk (AHOR = 2.11, P < 0.001) but decreased regular uptake risk (AHOR = 0.69, P = 0.026). Young adult occasional and experimental smoking uptake increased in the United States for non-smoking high school seniors graduating from 1976 to 2005. Smoking uptake for these cohorts remained most likely to occur at age 19/20, but prevalence of uptake at older ages increased. © 2015 Society for the Study of Addiction.

Using electronic diaries, the present study examined the roles of social smoking and smoking motives in relation to cigarette use patterns among Asian American college smokers. Multilevel modeling results showed that participants smoked more cigarettes when smoking with peers than when smoking alone. Participants' coping (but not social) motives moderated the within-person associations between smoking with peers and the cigarettes smoked during a smoking episode. The findings support the utility of an ecological perspective in examining the dynamic interaction between smoking motives and the social settings of cigarette use, and call for further research on the social smoking behaviors in diverse populations. 2008 APA, all rights reserved

Effects of anti-smoking advertising on youth smoking: a review.

PubMed

Wakefield, Melanie; Flay, Brian; Nichter, Mark; Giovino, Gary

2003-01-01

This paper reviews empirical studies, encompassing community trials and field experiments, and evaluates government-funded anti-smoking campaigns, ecologic studies of population impact of anti-smoking advertising, and qualitative studies that have examined the effects of anti-smoking advertising on teenagers. We conclude that anti-smoking advertising appears to have more reliable positive effects on those in pre-adolescence or early adolescence by preventing commencement of smoking. It is unclear whether this is due to developmental differences, or is a reflection of smoking experience, or a combination of the two. In addition, it is evident that social group interactions, through family, peer and cultural contexts, can play an important role in reinforcing, denying, or neutralizing potential effects of anti-smoking advertising. Although there is some research to suggest that advertising genres that graphically depict the health effects of smoking, emphasize social norms against smoking, and portray the tobacco industry as manipulative can positively influence teenagers, these findings are far from consistent. Finally, the effects of anti-smoking advertising on youth smoking can be enhanced by the use of other tobacco control strategies, and may be dampened by tobacco advertising and marketing. Overall, the findings of this review indicate that there is no single "recipe" for anti-smoking advertising that leads to reductions in youth smoking. Anti-smoking advertising can influence youth smoking, but whether it does in the context of individual anti-smoking campaigns needs to be the subject of careful evaluation.

The aim of the study was to analyze the nurse attitudes towards smoke-free regulations in public places. The study population consisted of 299 nurses. Among the study population questionnaire was conducted including socio-demographic characteristic, smoking and ETS profile, knowledge about health effects of smoking and abilities for conduction of antismoking counseling. Detail information was collected about nurse opinion on smoke-free public places such as offices, other workplaces, health and educational buildings, restaurants and bars. About 18% of study participants declared current tobacco smoking and 25% were former smokers. Almost all participating in the study women (85%-98%) are in favor of smoking ban in offices, health and educational buildings. 75% supported smoking ban in workplaces but 15% of them were somewhat opposed. Most of the nurses were in favor of smoke-free restaurants (64%) but they were less likely to support smoke-free bars, pubs and clubs (45%). Unfortunately 63% of interview women do not accept smoking ban in private cars. The percentage of women who support total ban of smoking in the presence of pregnant women was 93% and in the presence of children 79%. It is important to conduct educational and informational activities to increase public awareness on health consequences of active and passive smoking and the ways of elimination of such exposures.

Both in the programme and control groups of children from non-smoking families, the frequency of critics of adults smoking was significantly higher all the time of the study (p < 0.05 and 0.01 resp.); however, the programme influenced children's opinions about smoking (criticism) only partially. Children's actual intentions about their smoking in the future was fully influenced by their smoking household environment: the number of "future no-smokers" has decreased in time and was significantly less frequent among children from smoking families (p < 0.01). The frequency of those willing to smoke significantly increased within the period between 3rd and 5th grades, both in the programme and the control groups (p < 0.01). An almost linear increase of active experimentations with cigarette smoking in follow-up monitoring was seen, trends of smoking children were steeper in groups from smoking families. The number of experiments with smoking was significantly lower in programme children of non-smoking parents only at the end of the study (p < 0.05). Despite of the effort to initiate parental participation on the primary prevention of smoking, we have confirmed that smoking in families decreased the efficacy of anti-smoking intervention targeted on young children at school age.

To assess smoking behavior, knowledge of smoking harm, and attitudes toward campus smoking policy at an Egyptian university, an online survey of students, staff, and faculty was conducted (N = 992). The smoking prevalence of 38% among men was in line with Egypt's national average, but the smoking prevalence among women of 20% was much higher than the national average. Smoking status influenced beliefs about smoking harm and attitudes toward smoking policy, with nonsmokers having stronger beliefs about the harm of smoking and showing stronger support for smoking regulations than smokers. Smokers were more knowledgeable about smoking policy than were nonsmokers and differed slightly in their preferences for smoking policy enforcement strategies. These findings contribute to our understanding of how to tailor college smoking policy and programs to an Egyptian context.

Smoking in top-grossing movies--United States, 2010.

PubMed

2011-07-15

The National Cancer Institute has concluded that studies indicate a causal relationship between exposure to depictions of smoking in movies and youth smoking initiation. Adolescents in the top quartile of exposures to onscreen tobacco incidents have been found to be approximately twice as likely to begin smoking as those in the bottom quartile. The 2010 U.S. Department of Health and Human Services strategic plan to reduce tobacco use includes reducing youth exposure to onscreen smoking. To monitor tobacco use in movies, Thumbs Up! Thumbs Down! (TUTD), a project of Breathe California of Sacramento-Emigrant Trails, counts occurrences of tobacco incidents in U.S. top-grossing movies each year. This report updates a previous report with the latest TUTD findings. In 2010, the number of onscreen tobacco incidents in youth-rated (G, PG, or PG-13) movies continued a downward trend, decreasing 71.6% from 2,093 incidents in 2005 to 595 in 2010. Similarly, the average number of incidents per youth-rated movie decreased 66.2%, from 20.1 in 2005 to 6.8 in 2010. The degree of decline, however, varied substantially by motion picture company. The three companies with published policies designed to reduce tobacco use in their movies had an average decrease in tobacco incidents of 95.8%, compared with an average decrease of 41.7% among the three major motion picture companies and independents without policies. This finding indicates that an enforceable policy aimed at reducing tobacco use in youth-rated movies can lead to substantially fewer tobacco incidents in movies and help prevent adolescent initiation of smoking.

As the relationship between tobacco smoking and acne remains unclear, we examined the relationship between cigarette smoking and severe acne in a large cohort of young men. Trained nurses interviewed subjects upon discharge from compulsory military service, regarding family history, habits, and tobacco smoking habits. Data was correlated with severe acne status, as diagnosed and coded by board-certified dermatologists. In total, 27,083 male subjects participated in the study from 1983 to 2003, of which 237 (0.88%) had severe acne, 11,718 (43.27%) were active smokers, and 15,365 (56.73%) were nonsmokers at the time of interviews. Active smokers showed a significantly lower prevalence of severe acne (0.71%) than nonsmokers (1.01%) (P = 0.0078). An inverse dose-dependent relationship between severe acne prevalence and daily cigarette consumption became significant from 21 cigarettes a day (chi2 and trend test: P < 0.0001), odds ratio: 0.2 (95% CI: 0.06-0.63). The study did not aim to establish a temporal correlation, and passive smoking and acne treatments were not measured. Previous in vitro and clinical studies strongly support an association with nicotine. We suggest a trial with topical nicotine treatment for acne to further investigate this association.

The association between some factors of the familial and social environment with smoking in non-student adolescents with asthma has not been explored. The aim of the study was to determine the association between family structure, educational level, parental approval of smoking, parents who smoke, and smoking friends with smoking in non-student adolescents with asthma. In a cross-sectional study, data were obtained by means of a structured questionnaire applied to 4,778 non-student adolescents aged 13-18 years. Diagnosis of asthma was performed using a questionnaire based on the International Study of Asthma and Allergy in Childhood questionnaire. The smoking habit was determined by application of a self-administered questionnaire. Odds ratios (OR) were determined for smoking using logistic regression. From the total sample, asthma prevalence was 6.6% and of active smoking, 34.2%. Age at initiation of asthma symptoms was 5.15±3.52 years, and that of active smoking was 13.65±2.07 years. Percentage of non-intact family (40.1 vs. 32.7%) was greater in the group of adolescents with asthma. Logistic regression models show that parental approval of smoking (adjusted OR=5.57; 95% confidence interval=2.48-12.51) and smoking friends (adjusted OR=2.92; 95% confidence interval=1.04-8.19) are associated with smoking in non-student adolescents with asthma. In this study, parental approval of smoking and having friends who smoke appear to be associated with smoking among non-student adolescents with asthma. Copyright © 2011 SEPAR.

To examine whether the observed diversity between national patterns of smoking prevalence could require modification of the World Health Organization (WHO) linear model for an international 'smoking pandemic' (a worldwide epidemic) to address data from non-western countries. We conducted secondary research using current measures in three publicly available databases: Globalink, the International Labour Organization and the World Bank (all Internet-accessible). The measures we used are the separate percentage data for men and women on: smoking and employment and national income per capita (US$) and percentage growth per annum. Regression analysis showed that women smokers were more frequent in countries with higher national income, but women were less likely to smoke in countries of rapid growth. Men were less likely to smoke in countries with higher national income, but more likely to smoke in countries of rapid growth. Two principle components together explained 62% of all the variance in the international data. The largest factor was positively correlated with the percentage of employed females, the percentage of female smokers and national income per capita, but negatively correlated with the percentage of male smokers and percentage annual. growth. The effect of female employment was not continuous, but above a threshold of 51%, was associated with a higher prevalence of female smoking. The smaller, second factor was only weakly correlated with any smoking variables. In his 1994 model (subsequently adopted by the WHO) Lopez looked at historical trends in 'stages' of smoking prevalence. These have been associated with 'stages' of economic development. We extended this analysis to look at a dynamic change (% annual growth) and a social indicator (employment). Male and female smoking is affected differentially by economic change and by level of income. These are also strongly related to the percentage of women in employment. This has implications for workplace

This study assessed the utility of spousal smoking as a measure of secondhand smoke exposure. Methods The investigation involved secondary analysis of data from 526 female participants of a lung cancer case-control study from northeastern England. Secondhand smoke exposure was measured in the home (spousal and nonspousal), workplace, and social/other settings over the whole life course. Almost all women (99.1%) had at least 10 years of secondhand smoke exposure from at least one source, most commonly from parental smoking in childhood, and spousal smoking, the workplace, and social settings during adulthood. Spousal smoking was strongly correlated with overall secondhand smoke exposure in the home over the life course but was weakly correlated (Kendall's tau = -.04 to .12) with secondhand smoke exposure from other domestic sources and with secondhand smoke exposure in the workplace or social/other settings. Most women who gave no history of spousal secondhand smoke exposure recalled at least 10 years of secondhand smoke exposure in other settings: in the home through other sources (83.2% > or = 10 "smoker-years"), through workplaces (63.4% > or =10 "exposure-years"), or in social settings (82.0% > or =10 exposure-years). Almost all (96.9%) reported at least 10 years of exposure from at least one of these nonspousal sources. Using spousal smoking as a proxy of total secondhand smoke exposure would have meant that these subjects would have been misclassified as not exposed to secondhand smoke. This misclassification may bias estimates of association with health outcomes toward the null. Studies of the effects of secondhand smoke exposure on health outcomes should evaluate all potential sources of secondhand smoke exposure.

Although active tobacco smoking has been considered a major risk factor for head and neck cancer, few studies have evaluated environmental tobacco smoke (ETS) and its interaction with mutagen sensitivity on the risk of head and neck cancer. We investigated the relationship between ETS and head and neck cancer in a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. A structured questionnaire was used to collect ETS exposure and other covariates including a history of active tobacco smoking and alcohol use. ETS measures include a history of ETS exposure at home and at workplace. The associations between passive smoking and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Additive and multiplicative models were used to evaluate effect modifications between ETS and mutagen sensitivity. The crude odds ratio (OR) for ETS exposure was 2.8 [95% confidence intervals (CI), 1.3-6.0]. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and marijuana use, the risk of squamous cell carcinoma of the head and neck was increased with ETS (adjusted OR, 2.4; 95% CI, 0.9-6.8). Dose-response relationships were observed for the degree of ETS exposure; the adjusted ORs were 2.1 (95% CI, 0.7-6.1) for those with moderate exposure and 3.6 (95% CI, 1.1-11.5) for individuals with heavy exposure (P for trend = 0.025), in comparison with those who never had ETS exposures. These associations and the dose-response relationships were still present when the analysis was restricted to nonactive smoking cases and controls (crude OR, 2.2; 95% CI, 0.6-8.4). Crude odds ratios were 1.8 for those with moderate ETS exposure and 4.3 for individuals with heavy ETS exposure among nonsmoking cases and controls (P for trend = 0.008). More

Giant desiccation fissures on the Black Rock and Smoke Creek Deserts, Nevada

Open fissures, from 100 to several hundred feet apart, that have produced polygonal patterns on the Black Rock Desert, Nevada, are believed to be giant desiccation cracks resulting from a secular trend toward aridity in the last few decades. Similar features on the Smoke Creek Desert probably have the same origin.
