    Objectives. We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. Methods. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64 397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay–lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Results. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians–gays, Asian American and Pacific Islander lesbians–gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Conclusions. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking. PMID:24825218

    Data from National Health and Nutrition Examination Survey for the years 2011-2012 were used to evaluate variability in the observed levels of 19 urinary metabolites of 15 parent volatile organic compounds (VOCs) by age, gender, race/ethnicity, and smoking status. Smokers were found to have statistically significantly higher adjusted levels than nonsmokers for selected urinary metabolites of acrolein, acrylamide, acrylonitrile, 1,3-butadiene, carbon-disulfide, crotonaldehyde, cyanide, N,N-dimethylformamide, ethylbenzene-styrene, propylene oxide, styrene, and xylene. Female nonsmokers were found to have lower adjusted levels of selected metabolites of acrolein, carbon-disulfide, and N,N-dimethylformamide than male nonsmokers but female smokers had higher levels of each of these metabolites than male smokers. In addition, female smokers also had higher adjusted levels of selected metabolites of 1,3-butadiene, crotonaldehyde, cyanide, and ethylbenzene-styrene. Thus, constituents other than VOCs in tobacco smoke affect excretion of certain VOC metabolites differently among males and females. Non-Hispanic whites (NHW) had higher adjusted levels than non-Hispanic blacks (NHB) for 8 metabolites. NHB had statistically significantly lower adjusted levels than Hispanics for 5 VOC metabolites and lower levels than non-Hispanic Asians (NHAS) for 6 metabolites. Hispanics had statistically significantly higher levels than NHAS for 5 metabolites. Levels of 11 of the 19 metabolites analyzed increased with increase in age. Exposure to environmental tobacco smoke at home was associated with increased levels of 9 metabolites. Increase in the number of days tobacco products were used during the last five days was associated with increased levels of 12 of the 19 VOC metabolites. PMID:26282484

  3. Trends and variability in the levels of urinary thiocyanate, perchlorate, and nitrate by age, gender, race/ethnicity, smoking status, and exposure to environmental tobacco smoke over 2005-2012.

    Jain, Ram B

    Data from National Health and Nutrition Examination Survey for 2005-2012 were used to study the trends and variability in the levels of urinary thiocyanate (u-SCN), perchlorate (u-P8), and nitrate (u-NO3) by gender, race/ethnicity, active smoking, and exposure to environmental tobacco smoke (ETS) at home for those aged 12-19 and ≥20years old. For those aged ≥20years, adjusted levels of u-SCN, u-P8, and u-NO3 (i) were lower for males than females (p<0.01), and (ii) were higher for non-Hispanic white (NHW) than non-Hispanic black (NHB) (p<0.01). Also, for those aged ≥20years NHB had higher adjusted levels than Mexican American (MA) for u-SCN (p<0.01) but NHB had lower adjusted levels than MA for u-P8 (p<0.01) and u-NO3 (p<0.01). For those aged 12-19years, adjusted levels of u-SCN, u-P8, and u-NO3 did not vary by gender (p>0.05), and adjusted levels of u-P8 and u-NO3 for NHB were lower than for NHW (p<0.01) as well as higher for NHB than MA for u-SCN (p<0.01) and lower for NHB than MA (p<0.01) for u-P8 and u-NO3. Among those aged ≥20years, active smoking was associated with higher adjusted levels of u-SCN (p<0.01) in a dose-response manner and active smoking was associated with lower adjusted levels of u-P8 (p<0.01) in a dose-response manner. Exposure to ETS was associated with higher adjusted levels of u-SCN (p=0.02) and lower adjusted levels of u-P8 (p<0.01) among ≥20years old. Adjusted levels of u-P8 decreased over 2005-2012 among both 12-19 (p<0.01) and ≥20years old (p=0.04). There was borderline increase in the adjusted levels of u-NO3 for those aged ≥20years (p=0.05) over 2005-2012. PMID:26994809

    Aims This study assesses how race/ethnicity and socioeconomic status (SES) modify the relationship between exposure to movie smoking and having tried smoking in adolescents. Design Data come from a cross-sectional telephone survey and were analyzed using logistic regression models. A respondent reporting ever having tried smoking was regressed on exposure to movie smoking, race, socioeconomic status, the interactions of these variables, and family and background characteristics. Setting National sample of US adolescents. Participants 3653 respondents aged 13–18 years. Measurements Outcome was if subjects reported ever having tried smoking. Movie smoking exposure was assessed through respondents’ reporting having watched a set of movie titles, which were coded for smoking instances. Findings The proportion having tried smoking was lower for Blacks (0.32) compared to Hispanics (0.41) and Whites (0.38). The relationship between movie smoking and having tried smoking varied by race/ethnicity. Among Whites and Hispanics exposure to movie smoking positively predicted smoking behavior, but movie smoking had no impact on Blacks. SES further modified the relation among Whites; high SES white adolescents were more susceptible to movie smoking than low SES white adolescents. Conclusions Exposure to movie smoking is not uniformly experienced as a risk factor for having ever tried smoking among U.S. adolescents. Whites and Hispanics are more likely to try smoking as a function of increased exposure to movie smoking. In addition, higher socioeconomic status increases susceptibility to movie smoking among Whites. Youth with fewer risk factors may be more influenced by media messages on smoking. PMID:22724674

    We examined the association between parenting young children and smoking among US single women compared with married women, and whether this effect is moderated by socioeconomic status and race/ethnicity. Our main finding is that having children reduces smoking except among single white women, and women with low income. We used the Tobacco Use Supplement of the Current Population Survey, a nationally representative dataset (1995-96, n=70,019). Log-binomial regression analysis was used to estimate the association between parenting responsibility (i.e., presence of children aged 0-4 and 5-17) and daily smoking status, after taking into consideration marital status, income, and race/ethnicity. Single women faced a higher risk of smoking than married women. Parenting was protective against smoking among married women but not among single women. Additionally, among single women, the associations between parenting and smoking varied by income and race/ethnicity. Parenting increased the risk of smoking among single women in the lowest income quartile. Single black and Hispanic women with children had a risk of smoking similar to that of their childless counterparts. However, single white women with children were more likely to smoke than their childless counterparts. Smoking cessation interventions and programs to reduce environmental tobacco smoke should recognize that the co-occurrence of single motherhood, parenting responsibility and low-income may increase the risk of smoking. This is particularly significant given the rapid growth of the single women population, and their concentration in poverty in the USA. The finding that parenting is protective against smoking among single minority women, who presumably experience significant stressors, calls for a more thorough investigation of smoking behavior among minority women, and suggests the importance of stress buffers such as social support.

    Smoking in combination with other behavioral risk factors is known to have a negative influence on health, and individuals who smoke typically engage in multiple risk behaviors. However, little is known about the clustering of risk behaviors among smokers of varying race/ethnicity. The purpose of this study was to examine patterns of cancer risk behaviors and to identify predictors of multiple risk behaviors in a racially/ethnically diverse sample of individuals seeking smoking cessation treatment. Overweight/obesity, at-risk alcohol consumption, and insufficient physical activity were measured in 424 smokers (African American, n = 144; Latino, n = 141; Caucasian, n = 139). Results indicated that 90% of participants reported behavioral cancer risk factors in addition to smoking. Approximately 70% of participants were overweight or obese, 48% engaged in at-risk drinking, and 27% were insufficiently physically active. Univariate analyses indicated that race/ethnicity, p < .001, smoking level, p = .03, and marital status, p = .04, were significant predictors of multiple risk behaviors, although only race/ethnicity remained a significant predictor, p < .001, when gender, smoking level, age, education, household income, marital status, and health insurance status were included in a multivariate model. Multivariate analysis indicated that the odds of engaging in multiple risk behaviors were significantly higher among Latinos, OR = 2.85, and African Americans, OR = 1.86, than Caucasians. Our findings highlight the need for research aimed at identifiying determinants of racial/ethnic differences in multiple risk behaviors, and indicate the importance of developing culturally sensitive interventions that target multiple risk behaviors.

    This study of youth smoking onset aims to replicate previously published media moderation effects for race/ethnicity in a national longitudinal multiethnic sample of U.S. adolescents. Previous research has demonstrated that associations between media and smoking during adolescence are greater for Whites than Hispanics or Blacks, and for youth living in non-smoking families. In this study, changes in smoking status over 24 months were assessed among 4,511 baseline never-smokers. The incidence of smoking onset was 14.3% by 24 months with no differences by race/ethnicity. Blacks had higher exposure to movie smoking and overall television viewing compared with Whites and Hispanics. Whites responded to movie smoking regardless of parent smoking but more strongly if their parents were non-smokers. In contrast, Black adolescents showed little behavioral response to any media, regardless of parent smoking. Hispanic adolescents responded only to TV viewing and only when their parents did not smoke. In an analysis assessing the influence of the race of smoking characters on smoking behavior of White and Black adolescents, Whites responded to both White and Black movie character smoking, whereas Blacks responded only to smoking by Black movie characters. Taken as a whole, the findings replicate and extend previous findings, suggesting media factors are more influential among adolescents at low to moderate overall risk for smoking. We draw analogies between these low-moderate risk adolescents and "swing voters" in national elections, suggesting that media effects are more apt to influence an adolescent in the middle of the risk spectrum, compared with his peers at either end of it.

  8. Smoking: additional burden on aging and death.

    Tobacco smoking is a major cause of lung cancer. It has been suggested that there is an approximately linear dose-response relationship between the number of cigarettes smoked per day and clinical outcome such as lung cancer mortality. It has also been proposed that there is a greater increase in mortality at high doses when the dose is represented by the duration of the smoking habit rather than the number of cigarettes. The multistep carcinogenesis theory indicates that a greater increase in mortality rate at high doses is possible, as is the case between aging and cancer, even though each dose-response relationship between a carcinogenic factor and a carcinogenic step forward is linear. The high incidence of lung cancer after long-term smoking and the decreased relative risk after smoking cessation suggests a similarity between the effects of smoking and aging. Prediction of lung cancer risk in former smokers by simple integration of smoking effects with aging demonstrated a good correlation with that estimated from the relative risk of the period of smoking cessation. In contrast to the smoking period, there appears to be a linear relationship between smoking strength and cancer risk. This might arise if the dose-response relationship between smoking strength and each carcinogenic step is less than linear, or the effects become saturated with a large dose of daily smoking. Such a dose-response relationship could lead to relatively large clinical effects, such as cardiovascular mortality, by low-dose tobacco smoke exposure, e.g., second-hand smoking. Consideration of the dose-response of each effect is important to evaluate the risk arising from each carcinogenic factor. PMID:27350823

    We investigated how visual experience with faces of a particular race affects subordinate group-level categorizations in Chinese and Israeli participants living in the respective countries. Categorization of faces by race, gender, and age was examined within subjects with participants who had only minimal experience with the other-race faces. As would be predicted by the previously documented other-race advantage effect, both Chinese and Israeli participants classified the race of the face more quickly and more accurately for other-race than for own-race faces. In contrast, the observers' race did not interact with the race of the rated face either for gender or for age categorization. The absence of these interactions suggests that the physiognomic characteristics that determine the gender and age of a face are universal, rather than race specific. Furthermore, these data suggest that determining the race of a face is not imposed as a first step in face processing, preempting the perception of other category-defining physiognomic characteristics.

  10. Association of smoking status, cumulative smoking, duration of smoking cessation, age of starting smoking, and depression in Korean adults

    2012-01-01

    Background Many previous studies did not sufficiently control for several confounding factors that may affect the association between smoking and depression, such as socioeconomic status. We investigated the association between depression and smoking status, smoking exposure, duration of smoking cessation, and age of starting smoking while controlling for socioeconomic factors. Methods This study was based on a community health survey performed in Jeollanam-do, South Korea, between September and November 2009. In total, 20,084 subjects (9,118 males and 10,966 females) were included in the analysis. Information on smoking characteristics, such as smoking status, pack-years of smoking, and age of starting smoking, was collected using a standardized questionnaire. Depression was defined using the Korean CES-D score. Results The odds ratios (ORs) of depression were 1.35 (0.92–1.98) for former smokers and 1.77 (1.27–2.48) for current-smokers among males, and 2.67 (1.38–5.16) for former smokers and 3.72 (2.11–6.54) for current-smokers among females, after adjusting for other confounding factors. Compared to light smoking, heavy smoking was significantly associated with depression in males [OR = 3.97, 95% confidence interval (CI) = 1.42–11.14], but not in females (OR = 1.24, 95% CI = 0.73–2.09). No significant associations between depression and age of starting smoking and duration of smoking cessation were observed among former smokers. Conclusions Our data demonstrate that smoking is strongly associated with depression, particularly among females. These findings suggest that depression prevention may need to be combined with smoking prevention and that different strategies may be needed for males and females. PMID:22938088

  12. Age related changes in age of starting to smoke.

    The Average Age of Starting to Smoke (AASS) has been reported to decline for younger birth cohorts. That apparent decline has been used to support a conclusion of an increase in smoking among younger individuals. However, in some cases the apparent decline is an artifact of the method of computation which arises when the quantity being averaged is related to a quantity used to classify subjects for comparison. In one other case, a second type of error arises because the distribution of smoking initiation with age changed in such a way that the proportion of individuals taking up smoking at older ages declined more rapidly than the proportion starting at younger ages. In fact, comparison of the 1970 National Health Interview Survey (NHIS) to the 1979/80 NHIS shows a uniform decrease in starting to smoke among teens and preteens. Examples are discussed which show that estimates of possible disease related factors actually experienced by a cohort are possible only if other suitable data are available for comparable representative sections of the population at different time periods and for different ages.

    We surveyed a random sample of 852 students at a large university in 2010-2011 to clarify associations between waterpipe tobacco smoking (WTS), ethnicity, and religion. Current (past 30 day) WTS was reported by 116 (14%) students, and 331 (39%) reported ever WTS. Middle Eastern ethnicity was associated with current WTS (odds ratio [OR] = 2.37; 95% confidence interval [CI] = 1.06, 5.34) and ever WTS (OR = 2.59; 95% CI = 1.22, 5.47). South Asian ethnicity was associated with lower odds for ever WTS (OR = 0.42; 95% CI = 0.21, 0.86), but there was no significant association between South Asian ethnicity and current WTS. Being an atheist and having lower religiosity were associated with both WTS outcomes. PMID:24564560

    Experiencing bullying as a victim is associated with negative health and health behavior outcomes, including substance use, among adolescents. However, understandings of protective factors – factors that enhance adolescents’ resilience to the negative consequences of bullying – remain limited. The current study investigates whether teacher involvement protects adolescent students from the association between being bullied due to race and smoking initiation. Students were recruited from 12 Kindergarten through 8th grade schools in an urban school district in the Northeast United States. The analytic sample included 769 students who responded to surveys in 5th or 6th grade (2009), and two years later in 7th or 8th grade (2011). Students primarily identified as Latino and/or Black, and 90% were eligible for free or reduced lunch. Fifty-four (7%) students initiated smoking between survey time points. Among students reporting lower teacher involvement, race-based bullying was associated with higher likelihood of smoking initiation (OR = 1.69, p = .03). In contrast, among students reporting higher teacher involvement, racebased bullying was not associated with higher likelihood of smoking initiation (OR = 0.95, p = .81). Results suggest that teacher involvement may protect students from the association between race-based bullying and smoking initiation. Enhancing teacher involvement among students experiencing race-based bullying in schools may limit smoking initiation. PMID:24955021

  3. Blood cadmium levels in women of childbearing age vary by race/ethnicity

    The heavy metal cadmium (Cd) is long-lived in the body and low-level cumulative exposure, even among non-smokers, has been associated with changes in renal function and bone metabolism. Women are more susceptible to the adverse effects of Cd and have higher body burdens. Due to increased dietary absorption of Cd in menstruating women and the long half-life of the metal, reproductive age exposures are likely important contributors to overall body burden and disease risk. We examined blood Cd levels in women of reproductive age in the US and assessed variation by race/ethnicity. Blood Cd concentrations were compared among female NHANES participants aged 20-44, who were neither pregnant nor breastfeeding. Sample size varied primarily based on inclusion/exclusion of smokers (n=1734-3121). Mean Cd concentrations, distributions and odds ratios were calculated using SUDAAN. For logistic regression Cd was modeled as high (the upper 10% of the distribution) vs. the remainder. Overall, Mexican Americans had lower Cd levels than other groups due to a lower smoking prevalence, smoking being an important source of exposure. Among never-smokers, Mexican Americans had 1.77 (95% CI: 1.06-2.96) times the odds of high Cd as compared to non-Hispanic Whites after controlling for age and low iron (ferritin). For non-Hispanic Blacks, the odds were 2.96 (CI: 1.96-4.47) times those of non-Hispanic Whites in adjusted models. Adjustment for relevant reproductive factors or exposure to environmental tobacco smoke had no effect. In this nationally representative sample, non-smoking Mexican American and non-Hispanic Black women were more likely to have high Cd than non-Hispanic White women. Additional research is required to determine the underlying causes of these differences.

    The social world is stratified. Social hierarchies are known but often disavowed as anachronisms or unjust. Nonetheless, hierarchies may persist in social memory. In three studies (total N > 200,000), we found evidence of social hierarchies in implicit evaluation by race, religion, and age. Participants implicitly evaluated their own racial group most positively and the remaining racial groups in accordance with the following hierarchy: Whites > Asians > Blacks > Hispanics. Similarly, participants implicitly evaluated their own religion most positively and the remaining religions in accordance with the following hierarchy: Christianity > Judaism > Hinduism or Buddhism > Islam. In a final study, participants of all ages implicitly evaluated age groups following this rule: children > young adults > middle-age adults > older adults. These results suggest that the rules of social evaluation are pervasively embedded in culture and mind. PMID:25079218

    This study tested the effects of aging and race on responses to noxious stimuli using a wide range of stimulus modalities. The participants were 53 non-Hispanic Blacks and 138 non-Hispanic White adults, ages 45 to 76. The participants completed a single 3-hour sensory testing session where responses to thermal, mechanical, and cold stimuli were assessed. The results suggest that there are selected age differences, with the older group less sensitive to warm and painful heat stimuli than middle-aged participants, particularly at the knee. This site effect supports the hypothesis that the greatest decrement in pain sensitivity associated with aging occurs in the lower extremities. In addition, there were several instances where age and race effects were compounded, resulting in greater race differences in pain sensitivity among the older participants. Overall, the data suggest that previously reported race differences in pain sensitivity emerged in our older samples, and this study contributes new findings in that these differences may increase with age in non-Hispanic Blacks for temporal summation and both heat and cold immersion tolerance. We have added to the aging and pain literature by reporting several small to moderate differences in responses to heat stimuli between middle and older age adults. PMID:24239561

    Nearly fifty years ago, the American Academy organized a conference and two issues of its journal "Daedalus" on the topic of "The Negro American." The project engaged top intellectuals and policy-makers around the conflicts and limitations of mid-1960s liberalism in dealing with race. Specifically, they grappled with the persistent question of how to integrate a forced-worker population that had been needed but that was socially undesirable once its original purpose no longer existed. Today, racism has been discredited as an idea and legally sanctioned segregation belongs to the past, yet the question the conference participants explored -- in essence, how to make the unwanted wanted -- still remains. Recent political developments and anticipated demographic shifts, however, have recast the terms of the debate. Gerald Early, guest editor for the present volume, uses Barack Obama's election to the presidency as a pretext for returning to the central question of "The Negro American" project and, in turn, asking how white liberalism will fare in the context of a growing minority population in the United States. Placing his observations alongside those made by John Hope Franklin in 1965, Early positions his essay, and this issue overall, as a meditation on how far we have come in America to reach "the age of Obama" and at the same time how far we have to go before we can overcome "the two worlds of race."

    A cross-sectional survey on tobacco use in the city of Alexandria, Egypt, used an interview questionnaire based on World Health Organization guidelines. The study in 2000 included 2120 participants aged 15 to 86 years. More than a quarter (27.2%) were current smokers (25.5% daily smokers and 1.7% occasional smokers) and 3.5% were ex-smokers. Current smokers spent 23.1% of their family income on tobacco. The prevalence of current smoking was significantly higher among men (48.5%) than women (1.5%) and the mean age of initiation of smoking was lower among men (18.1 years) than women (22.6 years). The high prevalence of tobacco use among men is of concern, so too is the likelihood that tobacco use will increase among women. Further research is needed into factors that prevent people from starting smoking and assist them stopping smoking. PMID:15603046

    Debate persists over whether different message strategies in anti-smoking campaigns are needed for audiences of different races or genders. This study considers the need for 'message segmentation', which is the process of differentiating the beliefs that might be the focus of messages for population subgroups. We have two aims: (i) lay out an approach that yields evidence about the necessity for message segmentation and (ii) demonstrate and assess findings from this approach using the formative evaluation for the Philadelphia Anti-Smoking Campaign. We examine whether associations between beliefs about quitting smoking and intention to quit are moderated by race (black/white) or gender. Data came from a representative sample of 501 adult smokers (46% black; 56% female) surveyed in July 2010 for the campaign's formative evaluation. Out of 26 beliefs about cessation, 8 were significantly related to cessation intention regardless of subgroup affiliation, suggesting that these would be promising beliefs for messages in a unified campaign. Four beliefs were significant for white smokers only, and three beliefs were significant for female smokers only. The evidence justified a unified message approach because subgroups shared enough beliefs that could become message strategies to increase cessation across smokers without the added costs associated with message segmentation.

  10. Face age and sex modulate the other-race effect in face recognition.

    Faces convey a variety of socially relevant cues that have been shown to affect recognition, such as age, sex, and race, but few studies have examined the interactive effect of these cues. White participants of two distinct age groups were presented with faces that differed in race, age, and sex in a face recognition paradigm. Replicating the other-race effect, young participants recognized young own-race faces better than young other-race faces. However, recognition performance did not differ across old faces of different races (Experiments 1, 2A). In addition, participants showed an other-age effect, recognizing White young faces better than White old faces. Sex affected recognition performance only when age was not varied (Experiment 2B). Overall, older participants showed a similar recognition pattern (Experiment 3) as young participants, displaying an other-race effect for young, but not old, faces. However, they recognized young and old White faces on a similar level. These findings indicate that face cues interact to affect recognition performance such that age and sex information reliably modulate the effect of race cues. These results extend accounts of face recognition that explain recognition biases (such as the other-race effect) as a function of dichotomous ingroup/outgroup categorization, in that outgroup characteristics are not simply additive but interactively determine recognition performance.

    Since aged and diluted smoke particles are in general smaller and more stable than mainstream tobacco smoke, it should be possible to model their deposition on the basis of their measured particle diameters. However in practice, measured deposition values are consistently greater than those predicted by deposition models. Thus the primary objective of this study was to compare theoretical predictions obtained by the Monte Carlo code IDEAL with two human deposition studies to attempt to reconcile these differences. In the first study, male and female volunteers inhaled aged and diluted sidestream tobacco smoke at two steady-state concentrations under normal tidal breathing conditions. In the second study, male volunteers inhaled aged and diluted sidestream smoke labelled with 212Pb to fixed inhalation patterns. Median particle diameters in the two studies were 125 nm (CMD) and 210 nm (AMD), respectively. Experimental data on total deposition were consistently higher than the corresponding theoretical predictions, exhibiting significant inter-subject variations. However, measured and calculated regional deposition data are quite similar to each other, except for the extra-thoracic region. This discrepancy suggests that either the initial particle diameter decreases upon inspiration and/or additional deposition mechanisms are operating in the case of tobacco smoke particles.

    Perceived ethnic discrimination has been associated with cigarette smoking in US adults in the majority of studies, but gaps in understanding remain. It is unclear if the association of discrimination to smoking is a function of lifetime or recent exposure to discrimination. Some sociodemographic and mood-related risk factors may confound the relationship of discrimination to smoking. Gender and race/ethnicity differences in this relationship have been understudied. This study examines the relationship of lifetime and recent discrimination to smoking status and frequency, controlling for sociodemographic and mood-related variables and investigating the moderating role of race/ethnicity and gender. Participants included 518 Black and Latino(a) adults from New York, US. Lifetime and past week discrimination were measured with the Perceived Ethnic Discrimination Questionnaire-Community Version. Ecological momentary assessment methods were used to collect data on smoking and mood every 20 min throughout one testing day using an electronic diary. Controlling for sociodemographic and mood-related variables, there was a significant association of recent (past week) discrimination exposure to current smoking. Lifetime discrimination was associated with smoking frequency, but not current smoking status. The association of recent discrimination to smoking status was moderated by race/ethnicity and gender, with positive associations emerging for both Black adults and for men. The association of lifetime discrimination on smoking frequency was not moderated by gender or race/ethnicity. Acute race/ethnicity-related stressors may be associated with the decision to smoke at all on a given day; whereas chronic stigmatization may reduce the barriers to smoking more frequently.

  14. Age, sex and (the) race: gender and geriatrics in the ultra-endurance age.

    2014-01-01

    Ultra-endurance challenges were once the stuff of legend isolated to the daring few who were driven to take on some of the greatest physical endurance challenges on the planet. With a growing fascination for major physical challenges during the nineteenth century, the end of the Victorian era witnessed probably the greatest ultra-endurance race of all time; Scott and Amundsen's ill-fated race to the South Pole. Ultra-endurance races continued through the twentieth century; however, these events were isolated to the elite few. In the twenty-first century, mass participation ultra-endurance races have grown in popularity. Endurance races once believed to be at the limit of human durability, i.e. marathon running, are now viewed as middle-distance races with the accolade of true endurance going to those willing to travel significantly further in a single effort or over multiple days. The recent series of papers in Extreme Physiology & Medicine highlights the burgeoning research data from mass participation ultra-endurance events. In support of a true 'mass participation' ethos Knetchtle et al. reported age-related changes in Triple and Deca Iron-ultra-triathlon with an upper age of 69 years! Unlike their shorter siblings, the ultra-endurance races appear to present larger gender differences in the region of 20% to 30% across distance and modality. It would appear that these gender differences remain for multi-day events including the 'Marathon des Sables'; however, this gap may be narrower in some events, particularly those that require less load bearing (i.e. swimming and cycling), as evidenced from the 'Ultraman Hawaii' and 'Swiss Cycling Marathon', and shorter (a term I used advisedly!) distances including the Ironman Triathlon where differences are similar to those of sprint and endurance distances i.e. c. 10%. The theme running through this series of papers is a continual rise in participation to the point where major events now require selection races to remain

    The purpose of this study was to investigate pacing-profile differences during the 90 km Vasaloppet ski race related to the categories of sex, age, and race experience. Skiing times from eight sections (S1 to S8) were analyzed. For each of the three categories, 400 pairs of skiers were matched to have a finish time within 60 seconds, the same start group, and an assignment to the same group for the other two categories. Paired-samples Student's t-tests were used to investigate sectional pacing-profile differences between the subgroups. Results showed that males skied faster in S2 (P=0.0042), S3 (P=0.0049), S4 (P=0.010), and S1-S4 (P<0.001), whereas females skied faster in S6 (P<0.001), S7 (P<0.001), S8 (P=0.0088), and S5-S8 (P<0.001). For the age category, old subjects (40 to 59 years) skied faster than young subjects (19 to 39 years) in S3 (P=0.0029), and for the other sections, there were no differences. Experienced subjects (≥4 Vasaloppet ski race completions) skied faster in S1 (P<0.001) and S1-S4 (P=0.0054); inexperienced skiers (<4 Vasaloppet ski race completions) had a shorter mean skiing time in S5-S8 (P=0.0063). In conclusion, females had a more even pacing profile than that of males with the same finish time, start group, age, and race experience. No clear age-related pacing-profile difference was identified for the matched subgroups. Moreover, experienced skiers skied faster in the first half whereas inexperienced skiers had higher skiing speeds during the second half of the race. PMID:26937207

    To study the association of advanced maternal age (AMA) and race/ethnicity on placental pathology in very low birthweight (VLBW) infants. Retrospective analysis of placental pathology of inborn singleton VLBW infants from a regional level 3 NICU between July, 2002 and June, 2009. Subjects were stratified by age and race/ethnicity. Statistical analysis included One-way ANOVA, Chi Square and multivariable analyses. A total of 739 mother/infant dyads were included. AMA was associated with a decrease in placental weight and placental weight/birthweight ratio. Black/Non-Hispanic mothers ≥35 had a lower placental weight (p = 0.01) and lower placental weight/birth weight ratio (z-score, -0.45 ± 0.71 vs -0.04 ± 1.1, p = 0.01) compared to Black/Non-Hispanic mothers <35 years of age. After controlling for gestational age, race/ethnicity, maternal diabetes, maternal smoking, maternal hypertension and clinical chorioamnionitis, AMA, but not race/ethnicity, remained independently associated with placental weight/birthweight ratio z score (full model r(2) = 0.22, p < 0.01). In our study sample of VLBW infants, placental weight and placental weight/birthweight ratio were lower in mothers of advanced maternal age compared to mothers <35 years of age. Our data suggest that maternal age affects placentation in VLBW infants, which could influence maternal and neonatal outcomes. PMID:25567078

    2015-01-01

    ABSTRACT The running performance of Thoroughbred racehorses has been reported to peak when they are between 4 and 5 years old. However, changes in their racing speed by month or season have not been reported. The purposes of this study were to reveal the average racing speed of Thoroughbreds, and observe changes in their average speed with age. The surveyed races were flat races on turf and dirt tracks with firm or standard track conditions held by the Japan Racing Association from January 1st, 2002 to December 31st, 2010. The racing speed of each horse was calculated by dividing the race distance (m) by the horse’s final time (sec). Average speeds per month for each age and distance condition were calculated for each gender group when there were 30 or more starters per month for each age and distance condition for each gender group. The common characteristic change for all conditions was an average speed increase up until the first half of the age of 4 years old. The effect of increased carry weight on average speed was small, and average speed increased with the growth of the horse. After the latter half of the age of 4 years old, the horses’ average speed remained almost constant, with little variation. It is speculated that decreases in the weight carried; and the retirement of less well performing horses; are responsible for the maintenance of average speed. PMID:26170760

    Both facial cues of group membership (race, age, and sex) and emotional expressions can elicit implicit evaluations to guide subsequent social behavior. There is, however, little research addressing whether group membership cues or emotional expressions are more influential in the formation of implicit evaluations of faces when both cues are simultaneously present. The current study aimed to determine this. Emotional expressions but not race or age cues elicited implicit evaluations in a series of affective priming tasks with emotional Caucasian and African faces (Experiments 1 and 2) and young and old faces (Experiment 3). Spontaneous evaluations of group membership cues of race and age only occurred when those cues were task relevant, suggesting the preferential influence of emotional expressions in the formation of implicit evaluations of others when cues of race or age are not salient. Implications for implicit prejudice, face perception, and person construal are discussed. PMID:25046242

    Objectives. We determined whether racial/ethnic disparities existed in coverage by type of 100% smoke-free private workplace, restaurant, and bar laws from 2000 to 2009. Methods. We combined US census population data and the American Nonsmokers’ Rights Foundation US Tobacco Control Database to calculate the percentage of individuals in counties covered by each type of law by race/ethnicity from 2000 to 2009. Results. More of the US Hispanic and Asian populations were covered by 100% smoke-free restaurant and bar laws than non-Hispanic White and non-Hispanic Black populations. Asian coverage by smoke-free bars laws increased from 36% to 75%, and Hispanic coverage increased from 31% to 62%, compared with 6% to 41% for non-Hispanic Blacks and 8% to 49% for non-Hispanic Whites. Conclusions. Hispanics and Asians benefited more from the rapid spread of smoke-free law coverage, whereas non-Hispanic Blacks benefited less. These ethnic disparities suggest a likely effect of geographic region and may provide a basis for more effective, community-based, and tailored policy-related interventions, particularly regarding areas with high concentrations of non-Hispanic Blacks.

    A small percentage of the population associates smoking with ocular disease. Most optometrists do not stress the importance of smoking cessation to their patients, and the centrality of smoking regarding the risk for ocular disease is not emphasized in optometric education. Age-related macular degeneration has strong epidemiological associations with smoking, and so serves as an appropriate model for the adverse effects of cigarette smoke on the eye. This article aims to provide basic scientific information to optometrists and optometry students so that they can better understand the pathogenesis of age-related macular degeneration and provide education and support to their patients wishing to stop smoking.

  10. Own-race and own-age biases facilitate visual awareness of faces under interocular suppression

    2014-01-01

    The detection of a face in a visual scene is the first stage in the face processing hierarchy. Although all subsequent, more elaborate face processing depends on the initial detection of a face, surprisingly little is known about the perceptual mechanisms underlying face detection. Recent evidence suggests that relatively hard-wired face detection mechanisms are broadly tuned to all face-like visual patterns as long as they respect the typical spatial configuration of the eyes above the mouth. Here, we qualify this notion by showing that face detection mechanisms are also sensitive to face shape and facial surface reflectance properties. We used continuous flash suppression (CFS) to render faces invisible at the beginning of a trial and measured the time upright and inverted faces needed to break into awareness. Young Caucasian adult observers were presented with faces from their own race or from another race (race experiment) and with faces from their own age group or from another age group (age experiment). Faces matching the observers’ own race and age group were detected more quickly. Moreover, the advantage of upright over inverted faces in overcoming CFS, i.e., the face inversion effect (FIE), was larger for own-race and own-age faces. These results demonstrate that differences in face shape and surface reflectance influence access to awareness and configural face processing at the initial detection stage. Although we did not collect data from observers of another race or age group, these findings are a first indication that face detection mechanisms are shaped by visual experience with faces from one’s own social group. Such experience-based fine-tuning of face detection mechanisms may equip in-group faces with a competitive advantage for access to conscious awareness. PMID:25136308

    2010-01-01

    The purpose of this research was to assess age- and race-based variation in within-persons changes in self-esteem over a 16-year period. We used hierarchical linear modeling with data from 3,617 adults aged 25 and older who were interviewed up to four times. Self-esteem increased, on average, over the course of the study period. At the same time, significant age variations around this trend were observed, with younger adults experiencing increases in self-esteem and older adults experiencing decreases. In general, race differences were not evident with respect to average levels or rates of change in self-esteem. However, a significant age by race interaction suggested that late life declines in self-esteem were steeper for blacks compared to whites. These findings suggest the presence of age- and race-based stratification with respect to self-esteem. Future work in this area should examine the health and well-being effects of declining self-esteem during old age. PMID:20230130

    To date, a number of reports have been published on the relation of cigarette smoking to age-related maculopathy, an important cause of blindness in the United States. However, few studies have examined the relation between smoking and the incidence of age-related maculopathy. In this report, the authors examine this association in persons aged 43-86 years (n = 3,583) at baseline who were participants in the baseline examination and 5-year follow-up of the Beaver Dam Eye Study, Beaver Dam, Wisconsin (1988-1990 and 1993-1995). Exposure data on cigarette smoking were obtained from questions about present and past smoking, duration of smoking, and the number of cigarettes smoked per day. Age-related maculopathy status was determined by grading stereoscopic color fundus photographs using the Wisconsin Age-related Maculopathy Grading System. After controlling for age, sex, vitamin supplement use, and beer consumption, men who smoked greater amounts of cigarettes were more likely to develop early age-related maculopathy (odds ratio (OR) per 10 pack-years smoked = 1.06, 95% confidence interval (CI) 1.00-1.13, p = 0.06) than men who had smoked less. This association was not observed in women. Men (OR = 3.21, 95% CI 1.09-9.45) and women (OR = 2.20, 95% CI 1.04-4.66) who were current smokers at the time of the baseline examination had significantly higher odds of developing large drusen (> or = 250 microns in diameter) after 5 years than those who had never smoked or who quit before the baseline study. Current or past history of cigarette smoking was not related to the incidence of retinal pigment epithelial depigmentation. The authors conclude that smoking appears to be related to the incidence of some lesions associated with early age-related maculopathy. PMID:9456998

  19. The effect of aging on smoke optical properties and scavenging characteristics

    Aging of smoke in dense smoke plumes is known to alter its size distribution and scavenging characteristics. In this paper, I review data pertaining to these processes and compare them to model simulations of the coagulation of smoke. Model simulations of the degree of smoke coagulation in the first few days after a nuclear war are summarized. The predicted size of smoke particles after several days of coagulation is found to be larger than that of any data pertaining to the absorption properties of smoke. Thus, it is suggested that more relevant data on the absorption properties of smoke is needed. I also review aging experiments pertaining to the number of cloud condensation nuclei in a smoke sample. I show that the fraction of smoke particles which act as CCN after aging depends on the number of particles initially present in the aging chamber. Smoke from an acetylene flame can quickly coagulate to sizes wherein nearly all of the particles act as CCN. On the other hand, only 10% of the smoke particles from an outdoor fire of gasoline and diesel fuel became CCN after 30 hours of aging. The development of CCN concentrations in this experiment may have been quenched by low initial concentrations in the aging chamber. Both experiments are consistent with particles as small as 0.08 micron in radius (and perhaps even smaller) acting as CCN. Model simulations of the coagulation of smoke particles above a large, intense fire show that coagulation would allow approximately 50% of the particles to become larger than 0.08 micron before the plume reaches cloud base. Furthermore, aging over several days time would transform nearly all the particles into the scavengable size range.

    Background Maternal smoking during pregnancy has been consistently related to low birthweight. However, older mothers, who are already at risk of giving birth to low birthweight infants, might be even more susceptible to the effects of maternal smoking. Therefore, this study aimed to examine the modified association between maternal smoking and low birthweight by maternal age. Methods Data were obtained from a questionnaire survey of all mothers of children born between 2004 and 2010 in Okinawa, Japan who underwent medical check-ups at age 3 months. Variables assessed were maternal smoking during pregnancy, maternal age, gestational age, parity, birth year, and complications during pregnancy. Stratified analyses were performed using a logistic regression model. Results In total, 92641 participants provided complete information on all variables. Over the 7 years studied, the proportion of mothers smoking during pregnancy decreased from 10.6% to 5.0%, while the prevalence of low birthweight did not change remarkably (around 10%). Maternal smoking was significantly associated with low birthweight in all age groups. The strength of the association increased with maternal age, both in crude and adjusted models. Conclusions Consistent with previous studies conducted in Western countries, this study demonstrates that maternal age has a modifying effect on the association between maternal smoking and birthweight. This finding suggests that specific education and health care programs for older smoking mothers are important to improve their foetal growth. PMID:26795494

    Colorectal cancer (CRC) incidence rates and mortality have been decreasing in the United States. Currently, states in the South have the smallest reduction in CRC mortality. The trends of CRC incidence rates in Georgia in comparison to the United States have not been investigated. We analyzed age-adjusted incidence rates of CRC in Georgia and the United States from 2000 to 2012 using data from SEER 18 registries. Age-adjusted incidence rates (95% CI) were calculated as cases per 100,000 to the 2000 US Standard population. CRC incidence rates were calculated for groupings based on age at time of diagnosis, race, sex, and geographic location within Georgia. Incidence rates were higher in males compared to females in Georgia. In Georgians age 50–64, incidence rates were higher compared to the US, while those ages 65+ displayed lower incidence rates. Black Georgians age 50–64 generally exhibited higher incidence rates of CRC and lower rates of decrease in incidence compared to other races in Georgia. Asian/Pacific Islander females age 50–64 in Georgia exhibited an increasing trend in incidence rate. Whites and blacks Georgians age 50–64 displayed higher incidence rates compared to the US, while Asian/Pacific Islanders displayed lower incidence rates. Greater incidence rates of CRC in rural and Greater Georgia were seen across all races when compared to overall rates in Georgia. Efforts should be made to address disparities in Georgia based on race and geographic location. Increased screening by colonoscopy or fecal occult blood testing, reduction of risk factors and promotion of healthy lifestyles can reduce CRC incidence rates. PMID:27042701

    There have been notable improvements in survival over the past 2 decades for gastrointestinal (GI) cancer. However, the degree of improvement by age, race, and sex remains unclear. We analyzed data from 9 population-based cancer registries included in the SEER program of the National Cancer Institute (SEER 9) in 1990 to 2009 (n = 288,337). The degree of survival improvement over time by age, race, and sex was longitudinally measured. From 1990 to 2009, improvements in survival were greater for younger age groups. For patients aged 20 to 49 years and diagnosed from 2005 to 2009, adjusted HRs (95% CIs) were 0.74 (95% CI, 0.66–0.83), 0.49 (95% CI, 0.37–0.64), 0.69 (95% CI, 0.65–0.76), 0.62 (95% CI, 0.54–0.69), and 0.56 (95% CI, 0.42–0.76), for cancer of the stomach, small intestine, colon, rectum and anus, respectively, compared with the same age groups of patients diagnosed during 1990 to 1994. Compared with African Americans, whites experienced greater improvement in small intestinal and anal cancer survival. Female anal cancer and regional anal cancer patients experienced no improvement. Our data suggest that different improvement in survival in age, sex and race exists. PMID:27406065

  3. A discrete-time analysis of the effects of more prolonged exposure to neighborhood poverty on the risk of smoking initiation by age 25.

    Evidence suggests that individuals who initiate smoking at younger ages are at increased risk for future tobacco dependence and continued use as well as for numerous smoking-attributable health problems. Identifying individual, household, and to a far lesser extent, contextual factors that predict early cigarette use has garnered considerable attention over the last several decades. However, the majority of scholarship in this area has been cross-sectional or conducted over relatively short windows of observation. Few studies have investigated the effects of more prolonged exposure to smoking-related risk factors, particularly neighborhood characteristics, from childhood through early adulthood. Using the 1970-2011 waves of the Panel Study of Income Dynamics merged with census data on respondents' neighborhoods, this study estimates a series of race-specific discrete-time marginal structural logit models for the risk of smoking initiation as a function of neighborhood poverty, as well as individual and household characteristics, from ages four through 25. Neighborhood selection bias is addressed using inverse-probability-of-treatment weights. Results indicate that more prolonged exposure to high (>20%) as opposed to low (<10%) poverty neighborhoods is associated with an increased risk of smoking onset by age 25, although consistent with prior literature, this effect is only evident among white and not nonwhite youth and young adults.

    2016-01-01

    OBJECTIVES: Smoking prevalence among Korean men in their thirties is substantially high (approximately 50%). An in-depth analysis of smoking trends among young adults in their twenties is necessary to devise antismoking policies for the next 10 years. This study aimed to identify the contributions of age, period, and birth cohort effects on smoking prevalence in young adults. METHODS: Subjects comprised 181,136 adults (83,947 men: 46.3%; 97,189 women: 53.7%) aged 19 to 30 years from the 2008-2013 Korea Community Health Survey. Smoking prevalence adjusted with reference to the 2008 population was applied to the age-period-cohort (APC) model to identify the independent effects of each factor. RESULTS: For men, smoking prevalence rapidly escalated among subjects aged 19 to 22 years and slowed down among those aged 23 to 30 years, declined during 2008 to 2010 but stabilized during 2011 to 2013, and declined in birth cohorts prior to 1988 but stabilized in subjects born after 1988. However, in APC models, smoking prevalence increased with age in the 1988 to 1991 birth cohort. In this birth cohort, smoking prevalence at age 19 to 20 years was approximately 24% but increased to 40% when the subjects turned 23 to 24 years. For women, smoking prevalence was too low to generate consistent results. CONCLUSIONS: Over the past six years and in recent birth cohorts, smoking prevalence in adults aged 19 to 30 years has declined and is stable. Smoking prevalence should be more closely followed as it remains susceptible to an increase depending on antismoking policies or social conditions. PMID:27197740

    While stereotypes about gender, race, and age (particularly old age) have been studied independently, few have examined the content of compound stereotypes that consider the intersection of gender, race, and age. Using a within-subjects design, we examined stereotypes as a function of target gender (male, female), race (Black, White), and age across the life span (adolescent, young adult, middle-aged, young-old, and old-old). Participants rated 20 target groups on 10 attributes representative of either an agentic (e.g., ambitious) or communal (e.g., considerate) orientation. Participants were presented only with categorical information (e.g., Black, 85-year-old, males), and ordering of categorical information and target groups was counterbalanced across participants. We hypothesized differential effects of target gender and race as a function of age. Multivariate analyses of variance on each attribute revealed significant main effects that supported traditional stereotype research, but significant interactions revealed a more complicated picture. Overall, results showed that while gender stereotypes about agency and communion generally hold up across the life span, they are more applicable to White than Black targets. Results also supported the notion that we hold unique stereotypes based on multiple social categories rather than simply perceiving one social category as more salient than another, which was best exemplified in the case of Black female targets that were less likely to be perceived in gender stereotypic ways across the life span. We suggest stereotype research needs to shift to accommodate for the complexity and diversity of real people. PMID:26610722

    This study examined the influence of age, gender and race on nitric oxide (NO) release over acupuncture points, meridian without acupoint, and non-meridian regions of the Pericardium (PC) and Bladder (BL) meridian as well as aging on LU meridian in 61 healthy subjects. Biocapture tubes were attached to the skin surface, and total nitrite and nitrate was biocaptured and quantified using chemiluminescence. In elder ages compared to adults, NO levels over the ventral forearm were significantly decreased over LU on radial regions but not altered over PC on medial regions. Conversely, NO content was elevated over BL regions only in overweight/obesity of elder ages. NO levels over PC regions were marginally elevated in overweight/obese males compared to females but did not alter between races. These results suggest a selective reduction of NO release over LU meridian with aging, which is consistent with a progressive decline in lung function and increase in chronic respiratory disease in elder ages. Increased NO levels along the BL meridian in older obese subjects may reflect a modified NO level along somatic-bladder pathway for counteracting bladder dysfunctions with aging. Both of them support somatic-organ connections in the meridian system associated with potential pathophysiological changes with aging. PMID:26621821

    Objective To describe national trends in discretionary calories from sugar sweetened beverage (SSB) and snacks by age-specific body weight categories and by age- and weight-specific race/ethnicity groups. Examining these sub-populations is important as population averages may mask important differences. Design and Methods We used 24-hour dietary recall data obtained from the National Health and Nutrition Examination Survey 2003–2010 among children aged 2 to 19 (N=14,092). Logistic and linear regression methods were used to adjust for multiple covariates and survey design. Results The number of calories from SSBs declined significantly for nearly all age-specific body weight groups. Among overweight or obese children, significant declines in the number of calories from SSBs were observed among Hispanic children aged 2 to 5 (117 kcal vs. 174 kcal) and white adolescents aged 12 to 19 (299 kcal vs. 365 kcal). Significant declines in the number of calories from salty snacks were observed among white children aged 2 to 5 (192 kcal to 134 kcal) and 6 to 11 (273 kcal vs. 200 kcal). Conclusions The decrease in SSB consumption and increase in snack consumption observed in prior research are not uniform when children are examined within sub-groups accounting for age, weight and race/ethnicity.

    Age-related changes in children’s associations of economic resources and race were investigated. The sample (N = 308) included 5–6 year-olds (n = 153, M = 6.01 years, SD = 0.33 years) and 10–11 year-olds (n = 155, M = 11.12 years, SD = 0.59 years) of African–American (n = 93), European–American (n = 92), Latino (n = 62), Asian–American (n = 23), and multi-racial or multi-ethnic (n = 26) background. Participants matched pairs of target children (African–American and European–American) with visual indicators of low, middle, and high economic status. Children’s associations of economic resources with racial groups changed with age, and reflected different associations at high, middle, and low levels of the economic spectrum. Specifically, children associated targets of both races with middle economic status at a comparable rate, and with age, increasingly associated targets of both races with indicators of middle economic status. By contrast, both younger and older children associated African–American targets with indicators of low economic status more frequently than European–American targets. Finally, children associated African–American targets with indicators of high economic status less frequently with age, resulting in a perceived disparity in favor of European–American targets at high economic status among older children that was not present among younger children. No differences were found by participants’ own racial or ethnic background. These results highlight the need to move beyond a dichotomized view (rich or poor) to include middle economic status when examining children’s associations of economic resources and race.

  11. The development of implicit attitudes. Evidence of race evaluations from ages 6 and 10 and adulthood.

    2006-01-01

    To understand the origin and development of implicit attitudes, we measured race attitudes in White American 6-year-olds, 10-year-olds, and adults by first developing a child-oriented version of the Implicit Association Test (Child IAT). Remarkably, implicit pro-White/anti-Black bias was evident even in the youngest group, with self-reported attitudes revealing bias in the same direction. In 10-year-olds and adults, the same magnitude of implicit race bias was observed, although self-reported race attitudes became substantially less biased in older children and vanished entirely in adults, who self-reported equally favorable attitudes toward Whites and Blacks. These data are the first to show an asymmetry in the development of implicit and explicit race attitudes, with explicit attitudes becoming more egalitarian and implicit attitudes remaining stable and favoring the in-group across development. We offer a tentative suggestion that mean levels of implicit and explicit attitudes diverge around age 10. PMID:16371144

    We sought to elucidate the associations of 13 items assessing negative perceptions about condom use with gender, age and race in a sample of clinic attendees. Patients from four clinics, in three US cities, were recruited (N = 928). Data were collected using audio-computer-assisted self-interviewing. The primary measure was a 13-item adapted version of the Condom Barriers Scale. Logistic regression and chi-square tests were employed to relate the 13 items to gender, age and race. Gender, race and age all had significant associations with negative perceptions of condoms and their use. A primary finding was a large number of significant differences between men and women, with negative perceptions more common among women than among men. For African Americans, especially women, negative perceptions were more common among older participants than among younger participants. In conclusion, important demographic differences regarding negative perceptions may inform the tailoring of intervention efforts that seek to rectify negative perceptions about condoms and thus promote condom use among individuals at risk for sexually transmitted infections (STIs) in the USA. On the other hand, our findings also suggest that the majority of STI clinic attendees may hold positive perceptions about condoms and their use; maintaining and building upon these positive perceptions via education, counselling, and access is also important.

    Purpose: The purpose of this study was to evaluate the age- and race-dependence of the breast fibroglandular tissue density based on three-dimensional breast MRI. Methods: The normal breasts of 321 consecutive patients including Caucasians, Asians, and Hispanics were studied. The subjects were separated into three age groups: Younger than 45, between 45 and 55, and older than 55. Computer algorithms based on body landmarks were used to segment the breast, and fuzzy c-means algorithm was used to segment the fibroglandular tissue. Linear regression analysis was applied to compare mean differences among different age groups and race∕ethnicity groups. The obtained parameters were not normally distributed, and the transformed data, natural log (ln) for the fibroglandular tissue volume, and the square root for the percent density were used for statistical analysis. Results: On the average, the transformed fibroglandular tissue volume and percent density decreased significantly with age. Racial differences in mean transformed percent density were found among women older than 45, but not among women younger than 45. Mean percent density was higher in Asians compared to Caucasians and Hispanics; the difference remained significant after adjustment for age, but not significant after adjusted for both age and breast volume. There was no significant difference in the density between the Caucasians and the Hispanics. Conclusions: The results analyzed using the MRI-based method show age- and race-dependence, which is consistent with literature using mammography-based methods. PMID:20632587

    The aim of this paper is to report the rate of current and ever cigarette smoking and explore correlates of current cigarette smoking among adolescents aged 13-15 in Viet Nam. This analysis was derived from GYTS survey, which comprised of 3,430 adolescents aged 13-15, conducted in 2014 in 13 cities and provinces of Viet Nam. We calculated the weighted rates of current and ever cigarette smoking and reported patterns of smoking behavior. We also performed logistic regression to explore correlates of current cigarette smoking behavior. The weighted rate of ever cigarette smoking was 9.5% (95% confidence interval (CI): 8.5 %-10.5%), in which the weighted rate among males (15.4%; 95% CI: 13.6%-17.0%) was higher than that among females (4.2%; 95% CI: 3.3%-5.1%). The weighted rate of current cigarette smoking was relatively low at 2.5% (95%CI: 2.0%- 3.0%) with higher weighted rate among males (4.9%; 95% CI: 3.8%-5.9%) compared to the corresponding figure among females (0.2%; 95% CI: 0.0 %-0.5%). Current cigarette smoking was significantly higher among males than females, in students aged 15 versus 13 years old, and in students who had several or all close friends smoking and students with daily observation of smoking at school. For greater smoking reduction outcomes, we recommend that tobacco interventions for adolescents should consider targeting more male students at older ages, establish stricter adherence to school-based banning of cigarette smoking, engage both smoking and nonsmoking adolescents and empower adolescents to resist peer smoking influence as well as changing their norms or beliefs towards smoking benefits.

    Purpose. To determine if laminar depth (LD) and prelaminar tissue volume (PTV) are associated with age and race in healthy human eyes. Methods. Optic nerve head images from enhanced depth imaging spectral-domain optical coherence tomography of 166 normal eyes from 84 subjects of African descent (AD) and European descent (ED) were manually delineated to identify the principal surfaces: internal limiting membrane, Bruch's membrane (BM), anterior sclera (AS), and anterior surface of the lamina cribrosa. These four surfaces defined the LD and PTV using Bruch's membrane opening (BMO) and AS for reference structures. Generalized estimating equations were used to evaluate whether the effect of age on each outcome was differential by race. Results. When age was analyzed as a continuous variable, the interaction term between age and race was statistically significant for mean LDBMO (P = 0.015) and mean LDAS (P = 0.0062) after adjusting for axial length and BMO area. For every 1-year increase in age, the LDAS was greater on average by 1.78 μm in AD subjects and less by 1.71 μm in ED subjects. Mean PTV was lower in the older subjects (1248 × 106 μm3 AD, 881 × 106 μm3 ED) compared to the younger subjects (1316 × 106 μm3 AD, 1102 × 106 μm3 ED) in both groups. Conclusions. With increasing age, the LD changes differently across racial groups in normal subjects. The LD in ED subjects showed a significantly decreasing slope suggesting that the lamina moves anteriorly with age in this group. PMID:25414182

    Objective The objective of this study was to consider race differences in age-trends of autonomic nervous system functioning, using a national dataset with a broad age range. Methods Measures of baseline heart rate variability (HRV) and HRV reactivity were derived from electrocardiograph (ECG) recordings taken at rest and during cognitive stress tasks. Age-trends in HRV and HRV reactivity were compared among 204 African Americans and 833 Whites ages 34 to 83 years (M=53.7, SD=11.4), before and after controlling for socioeconomic status (SES). Results For HRV-reactivity, age-trends were steeper among African Americans and lower-SES participants than Whites and higher-SES participants. For baseline HRV, age-trends varied by SES but not race. Discussion Results relating to HRV-reactivity (but not baseline HRV) were consistent with hypotheses suggesting that African Americans are exposed to higher levels of stress and experience accelerated declines in health across the life span. The relevance of the findings to research on social stress and health disparities is discussed. PMID:23781017

  18. Will the age of peak ultra-marathon performance increase with increasing race duration?

    PubMed Central

    2014-01-01

    Background Recent studies found that the athlete’s age of the best ultra-marathon performance was higher than the athlete’s age of the best marathon performance and it seemed that the athlete’s age of peak ultra-marathon performance increased in distance-limited races with rising distance. Methods We investigated the athlete’s age of peak ultra-marathon performance in the fastest finishers in time-limited ultra-marathons from 6 hrs to 10 d. Running performance and athlete’s age of the fastest women and men competing in 6 hrs, 12 hrs, 24 hrs, 48 hrs, 72 hrs, 144 hrs (6 d) and 240 hrs (10 d) were analysed for races held between 1975 and 2012 using analysis of variance and multi-level regression analysis. Results The athlete’s ages of the ten fastest women ever in 6 hrs, 12 hrs, 24 hrs, 48 hrs, 72 hrs, 6 d and 10 d were 41 ± 9, 41 ± 6, 42 ± 5, 46 ± 5, 44 ± 6, 42 ± 4, and 37 ± 4 yrs, respectively. The athlete’s age of the ten fastest women was different between 48 hrs and 10 d. For men, the athlete’s ages were 35 ± 6, 37 ± 9, 39 ± 8, 44 ± 7, 48 ± 3, 48 ± 8 and 48 ± 6 yrs, respectively. The athlete’s age of the ten fastest men in 6 hrs and 12 hrs was lower than the athlete’s age of the ten fastest men in 72 hrs, 6 d and 10 d, respectively. Conclusion The athlete’s age of peak ultra-marathon performance did not increase with rising race duration in the best ultra-marathoners. For the fastest women ever in time-limited races, the athlete’s age was lowest in 10 d (~37 yrs) and highest in 48 hrs (~46 yrs). For men, the athlete’s age of the fastest ever in 6 hrs (~35 yrs) and 12 hrs (~37 yrs) was lower than the athlete’s age of the ten fastest in 72 hrs (~48 yrs), 6 d (~48 yrs) and 10 d (~48 yrs). The differences in the athlete’s age of peak performance between female and male ultra-marathoners for the different race durations need further

    Older adults express greater prejudice than younger adults, but it is not clear why. In a community-based sample, we found that older White adults demonstrated more racial prejudice on an implicit measure, the race Implicit Association Test, than did younger adults. Process-dissociation procedures indicated that this difference in implicit prejudice was due to older adults having less control of their automatic prejudicial associations rather than stronger automatic prejudicial associations. Furthermore, this age difference in control was mediated by age-related deficits in inhibitory ability. White participants showed stronger automatic prejudicial associations than did Black participants. PMID:19175528

    OBJECTIVES: This study tested the hypothesis that women who deliver small-for-gestational-age infants are more often exposed to passive smoking at home or at work. METHODS: Among a 1-year cohort of nulliparous women in the city of Malmö, Sweden 872 (87.7%) women completed a questionnaire during their first prenatal visit. The study was carried out among women whose pregnancies resulted in a singleton live birth (n = 826), 6.7% of infants were classified as small for their gestational age. RESULTS: Passive smoking in early pregnancy was shown to double a woman's risk of delivering a small-for-gestational-age infant, independent of potential confounding factors such as age, height, weight, nationality, educational level, and the mother's own active smoking (odds ratio [OR] = 2.7). A stratified analysis indicated interactional effects of maternal smoking and passive smoking on relative small-for-gestational-age risk. CONCLUSIONS: Based on an attributable risk estimate, a considerable reduction in the incidence of small-for-gestational-age births could be reached if pregnant women were not exposed to passive smoking.

    OBJECTIVE: Investigation into the relationship between lifestyle factors (particularly cigarette smoking) and perceived oral health has been limited. Data from the third National Health and Nutrition Examination Survey (NHANES II), 1988-1994, were used to explore this relationship in a large sample of U.S. adults. METHODS: This study used data on 13,357 dentate participants in NHANES III aged 20-79 years. In NHANES III, information on perceived dental health, sociodemographic attributes, smoking status, frequency of dental visits, dental insurance, and general health perception were collected during a home interview, and oral health status was assessed at a mobile examination center. RESULTS: Overall, 34.4% of individuals in the study sample reported having an unfavorable perception of their dental health by qualifying it as "fair" or "poor." Furthermore, 46.6% of smokers had an unfavorable dental health perception, compared to 28.3% of non-smokers. An interaction between smoking and race/ethnicity was found in logistic regression modeling. Stratified results show that cigarette smoking was not a significant predictor for an unfavorable dental health perception among individuals who self-identified as Mexican American, but smoking was a significant predictor for an unfavorable dental health perception among those who identified as non-Hispanic black or non-Hispanic white. CONCLUSIONS: This is the first study to describe the effects of smoking on dental health perception while controlling for examined oral health status. Because perceived dental health is a potential indicator for dental care utilization, a better knowledge of the factors that influence dental health perception is not only important for dental services planning, but also for understanding oral health-related quality of life issues. Additionally, given that smoking may negatively affect dental health perception, these findings have potential implications for smoking cessation activities conducted by

    Large-scale representative surveys of 8th-, 10th-, and 12th-grade students in the United States show high self-esteem scores for all groups. African-American students score highest, Whites score slightly higher than Hispanics, and Asian Americans score lowest. Males score slightly higher than females. Multivariate controls for grades and college plans actually heighten these race/ethnic/gender differences. A truncated scoring method, designed to counter race/ethnic differences in extreme response style, reduced but did not eliminate the subgroup differences. Age differences in self-esteem are modest, with 12th graders reporting the highest scores. The findings are highly consistent across 18 annual surveys from 1991 through 2008, and self-esteem scores show little overall change during that period. PMID:22279425

  3. Timing the second birth: fecundability models for selected race and age groups in Hawaii.

    Swanson, D A

    1986-12-01

    This article tests exponential models for fecundability for use in predicting the timing of the second birth in a non-contracepting population, using data from Hawaii for reference. The paper begins with an extensive review of the literature on mathematical models for birth intervals. The most common problem with prior studies is that the reference data are often biased with uncontrolled parameters such as maternal age, abortion history, lactation practice and pregnancy planning. Pertinent bias in the present data is evaluated. The principal tool used here is an exponential distribution, maximum-likelihood method, involving partial differential equations. The model was constructed by subjecting it to 3 steps: 1) it was tested for exponentiality with a Gail-Gastwirth test that does not depend upon an unknown parameter; 2) the reciprocal of the mean second birth interval was calculated for each group that passed the first test; 3) the estimated frequencies were tested against observed by the chi-squared goodness of fit test. The results are tabulated as separate racial groups, combined races, and age groups. Fecundabilities varied widely by age within all races. For all races, rates were .07045, .03423 and .02777 for ages 20-24, 25-29, and 30-34. Thus the results suggest that fecundability rates are largely determined by age related factors associated with coital frequency, rather than by racial or physiological variations. Other factors potentially influencing fecundability in actual data or models are discussed, such as period effects, the "intendedness" of pregnancy, types of non-live birth intervals, lactation, induced and spontaneous abortion, and differences in pre- and post-demographic transition populations. Finally appendices are added discussing cohort size bias, presenting data set documentation and evaluating the length of pregnancy term and post-partum sterility in the data used here. PMID:12268733

    Purpose. We tested the hypothesis that there are age- and race-related differences in posterior scleral material properties, using eyes from human donors of European (20–90 years old, n = 40 eyes) and African (23–74 years old, n = 22 eyes) descent. Methods. Inflation tests on posterior scleral shells were performed while full-field, three-dimensional displacements were recorded using laser speckle interferometry. Scleral material properties were fit to each eye using a microstructure-based constitutive formulation that incorporates the collagen fibril crimp and the local anisotropic collagen architecture. The effects of age and race were estimated using Generalized Estimating Equations, while accounting for intradonor correlations. Results. The shear modulus significantly increased (P = 0.038) and collagen fibril crimp angle significantly decreased with age (P = 0.002). Donors of African descent exhibited a significantly higher shear modulus (P = 0.019) and showed evidence of a smaller collagen fibril crimp angle (P = 0.057) compared to donors of European descent. The in-plane strains in the peripapillary sclera were significantly lower with age (P < 0.015) and African ancestry (P < 0.015). Conclusions. The age- and race-related differences in scleral material properties result in a loss of scleral compliance due to a higher shear stiffness and a lower level of stretch at which the collagen fibrils uncrimp. The loss of compliance should lead to larger high frequency IOP fluctuations and changes in the optic nerve head (ONH) biomechanical response in the elderly and in persons of African ancestry, and may contribute to the higher susceptibility to glaucoma in these at-risk populations.

    The Hanford Environmental Does Reconstruction (HEDR) Project was established to estimate radiation doses that people could have received from nuclear operations at the Hanford Site since 1944. To identify groups that may have received doses, population estimates containing age, race, and sex detail for ten counties in Washington and Oregon for the years 1940 to 1980 were prepared by the Demographics Laboratory under a subcontract with the Pacific Northwest Laboratory (PNL). A data base of population information was developed from census reports and published and unpublished collections from the Washington State Office of Financial Management and Center for Population Research. Three estimation methods were then explored: the cohort-component model, cohort interpolation, and age-group interpolation. The estimates generated through cohort and age-group interpolation are considered adequate for initial use in the HEDR Project. Results are presented in two forms: (1) county populations by sex and single year of age and (2) county populations by sex and race for age groupings. These results are made available to the HEDR Project for further refinement into population estimates by county census divisions.

    Objectives. We characterized workplace secondhand smoke exposure among nonsmoking women of reproductive age as a proxy for workplace secondhand smoke exposure during pregnancy. Methods. We included nonsmoking women aged 18 to 44 years employed during the past 12 months who participated in the 2010 National Health Interview Survey. We estimated the prevalence of workplace secondhand smoke exposure and its associations with sociodemographic and workplace characteristics. Results. Nine percent of women reported workplace secondhand smoke exposure. Prevalence decreased with increasing age, education, and earnings. Workplace secondhand smoke exposure was associated with chemical exposure (prevalence odds ratio [POR] = 3.3; 95% confidence interval [CI] = 2.3, 4.7); being threatened, bullied, or harassed (POR = 3.2; 95% CI = 2.1, 5.1); vapors, gas, dust, or fume exposure (POR = 3.1; 95% CI = 2.3, 4.4); and worrying about unemployment (POR = 3.0; 95% CI = 1.8, 5.2), among other things. Conclusions. Comprehensive smoke-free laws covering all workers could eliminate inequities in workplace secondhand smoke exposure, including during pregnancy. PMID:25905837

    Summary To find an association between smoking and the development of myocardial infarction in male patients above forty years of age presenting at the echocardiology department of Sudan heart center Khartoum. A prospective cohort study was carried out at the echocardiography department of Sudan Heart Center in Khartoum-Sudan between July 2012 and June 2014. The study population comprised a total of 168 adult male patients who underwent cardiac ultrasound scanning. Out of a total of 144 cases, 65% (94) of patients were smokers, 74% of the 94 cases smoked for more than 10 years, and 26% of the 94 cases smoked for less than 10 years. With this study it was concluded that smoking is a risk factor for the development of myocardial infarction. This study showed that patients with myocardial infarction are more likely to have a past history of smoking. PMID:27081418

    The relative age effect (RAE), which refers to an over-representation of selected athletes born early in the selection year, was proven to be present in alpine ski racing in all age categories at both national and international levels. However, the influential factors on, or the causal mechanisms of, the RAE are still unknown. Therefore, the aim of the present study was to examine three possible influential factors on the relative age effect in alpine skiing: physical performance, anthropometric characteristics and biological maturational status. The study included the investigation of 282 elite Austrian youth ski racers and 413 non-athletes (comparison group) of the same age (10–13 years) and region. Six physical performance tests were performed, body mass and height were assessed, and the age at peak height velocity (APHV) was calculated. A significant RAE was present in the ski racers. No differences were shown in the physical performance characteristics or in the calculated APHV between the relative age quarters. These results suggest that ski racers born in the last quarter can counteract the relative age disadvantages if they already present the same level of physical performance and maturational status as those born at the beginning of the year. The height and weight of ski racers born at the beginning of the year were significantly higher compared to the non-athletes, and ski racers born in relative age quarter 1 were taller and heavier compared to the ski racers of the other quarters. This indicates that the anthropometric characteristics influence the selection process in alpine ski racing, and that relatively older athletes are more likely to be selected if they exhibit advanced anthropometric characteristics.

    The aim of the study was to examine the effects of tobacco smoking in pregnancy on children's IQ at the age of 5. A prospective follow-up study was conducted on 1,782 women, and their offspring were sampled from the Danish National Birth Cohort. At 5 years of age, the children were tested with the Wechsler Preschool and Primary Scale of Intelligence-Revised. Parental education, maternal IQ, maternal alcohol consumption in pregnancy, the sex and age of the child, and tester were considered core confounders, but the full model also controlled for prenatal paternal smoking, maternal age and Bodymass Mass Index, parity, family/home environment, postnatal parental smoking, breast feeding, the child's health status, and indicators for hearing and vision impairments. Unadjusted analyses showed a statistically significant decrement of 4 points on full-scale IQ (FSIQ) associated with smoking 10+ cigarettes per day compared to nonsmoking. After adjustment for potential confounders, no significant effects of prenatal exposure to tobacco smoking were found. Considering the indisputable teratogenic effects of tobacco smoking, these findings should be interpreted with caution. Still, the results may indicate that previous studies that failed to control for important confounders, particularly maternal intelligence, may be subject to substantial residual confounding.

    Recidivism of released prisoners, especially violent recidivism, is an important policy issue. Equally important is an understanding of how demographic risk factors may act as moderators of recidivism. Knowledge of such relationships is important in developing a deeper theoretical understanding of the risk of recidivism as well as identifying points of intervention that may need to be re-oriented to reduce recidivism. The present study conducts a meta-analytic review of the violent recidivism literature focusing on the role of several demographic risk factors. Findings show that age, sex, and race (Whites) were significantly related to violent recidivism. Implications and directions for future research are identified. PMID:24335783

    A major subset of human peripheral blood γδ T cells expresses the Vγ2Vδ2 T cell receptor (TCR) and responds to malignant or infectious diseases. We noted significant differences in the numbers of Vγ2Vδ2 T cells in blood samples from healthy Caucasian or African American (AA) donors. On average, CA donors had 3.71 ± 4.37% Vδ2 cells (as a percentage of total lymphocytes) compared to 1.18 ± 2.14% Vδ2 cells for AA donors (p < 0.0001). Age and race had the greatest impact on Vδ2 cell levels; the effect of age was similar for both racial groups. The Vδ2+ cell population was dominated, for both donor groups, by cells expressing the Vγ2-Jγ1.2 Vδ2 T cell receptor, an apparent result of strong positive selection and there was substantial overlap in the public Vγ2 clonotypes from both racial groups. Mechanisms for selection and amplification of Vδ2 cells are nearly identical for both groups, despite the significant difference in baseline levels. These data show that appropriate controls, matched for age and race, may be required for clinical studies of Vγ2Vδ2 T cells in infectious disease or cancer and raise important questions about the mechanisms regulating the levels of circulating Vδ2 cells.

    OBJECTIVES: To determine possible variations in the Anthropometric Index for pectus excavatum relative to age, race, and sex in individuals free of thoracic wall deformities. METHODS: Between 2002 and 2012, 166 individuals with morphologically normal thoracic walls consented to have their chests and the perimeter of the lower third of the thorax measured according to the Anthropometric Index for pectus excavatum. The participant characteristics are presented (114 men and 52 women; 118 Caucasians and 48 people of African descent). RESULTS: Measurements of the Anthropometric Index for pectus excavatum were statistically significantly different between men and women (11–40 years old); however, no significant difference was found between Caucasians and people of African descent. For men, the index measurements were not significantly different across all of the age groups. For women, the index measurements were significantly lower for individuals aged 3 to 10 years old than for individuals aged 11 to 20 years old and 21 to 40 years old; however, no such difference was observed between women aged 11 to 20 years old and those aged 21 to 40 years old. CONCLUSION: In the sample, significant differences were observed between women aged 11 to 40 years old and the other age groups; however, there was no difference between Caucasian and people of African descent.

    To examine the combined effect of birth weight, mothers' education and prenatal smoking on psychometrically measured intelligence at school age 1,822 children born in 1992-1999 and attending the first six grades from 45 schools representing all of the fifteen Estonian counties with information on birth weight, gestational age and mother's age, marital status, education, parity and smoking in pregnancy, and intelligence tests were studied. The scores of Raven's Standard Progressive Matrices were related to the birth weight: in the normal range of birth weight (>or=2500 g) every 500 g increase in birth weight was accompanied by around 0.7-point increase in IQ scores. A strong association between birth weight and IQ remained even if gestational age and mother's age, marital status, education, place of residence, parity and smoking during pregnancy have been taken into account. Maternal prenatal smoking was accompanied by a 3.3-point deficit in children's intellectual abilities. Marriage and mother's education had an independent positive correlation with offspring intelligence. We concluded that the statistical effect of birth weight, maternal education and smoking in pregnancy on offspring's IQ scores was remarkable and remained even if other factors have been taken into account.

  16. Biological Maturity Status Strongly Intensifies the Relative Age Effect in Alpine Ski Racing

    2016-01-01

    The relative age effect (RAE) is a well-documented phenomenon in youth sports. This effect exists when the relative age quarter distribution of selected athletes shows a biased distribution with an over-representation of relatively older athletes. In alpine ski racing, it exists in all age categories (national youth levels up to World Cup). Studies so far could demonstrate that selected ski racers are relatively older, taller and heavier. It could be hypothesized that relatively younger athletes nearly only have a chance for selection if they are early maturing. However, surprisingly this influence of the biological maturity status on the RAE could not be proven, yet. Therefore, the aim of the present study was to investigate the influence of the biological maturity status on the RAE in dependence of the level of competition. The study investigated 372 elite youth ski racers: 234 provincial ski racers (P-SR; high level of competition) and 137 national ski racers (N-SR; very high level of competition). Anthropometric characteristics were measured to calculate the age at peak height velocity (APHV) as an indicator of the biological maturity status. A significant RAE was present among both P-SR and N-SR, with a larger effect size among the latter group. The N-SR significantly differed in APHV from the P-SR. The distribution of normal, early and late maturing athletes significantly differed from the expected normal distribution among the N-SR, not among the P-SR. Hardly any late maturing N-SR were present; 41.7% of the male and 34% of the female N-SR of the last relative age quarter were early maturing. These findings clearly demonstrate the significant influence of the biological maturity status on the selection process of youth alpine ski racing in dependence of the level of competition. Relatively younger athletes seem to have a chance of selection only if they are early maturing. PMID:27504832

    Objectives: We assessed the association of smoking at diagnosis of inflammatory bowel disease (IBD) on the need for an intestinal resection. Methods: The Health Improvement Network was used to identify an inception cohort of Crohn's disease (n=1519) and ulcerative colitis (n=3600) patients from 1999–2009. Poisson regression explored temporal trends for the proportion of newly diagnosed IBD patients who never smoked before their diagnosis and the risk of surgery within 3 years of diagnosis. Cox proportional hazard models assessed the association between smoking and surgery, and effect modification was explored for age at diagnosis. Results: The rate of never smokers increased by 3% per year for newly diagnosed Crohn's disease patients (incidence rate ratio (IRR) 1.03; 95% confidence interval (CI): 1.02–1.05), but not for ulcerative colitis. The rate of surgery decreased among Crohn's disease patients aged 17–40 years (IRR 0.96; 95% CI: 0.93–0.98), but not for ulcerative colitis. Smoking at diagnosis increased the risk of surgery for Crohn's disease patients diagnosed after the age of 40 (hazard ratio (HR) 2.99; 95% CI: 1.52–5.92), but not for those diagnosed before age 40. Ulcerative colitis patients diagnosed between the ages of 17 and 40 years and who quit smoking before their diagnosis were more likely to undergo a colectomy (ex-smoker vs. never smoker: HR 1.66; 95% CI: 1.04–2.66). The age-specific findings were consistent across sensitivity analyses for Crohn's disease, but not ulcerative colitis. Conclusions: In this study, the association of smoking and surgical resection was dependent on the age at diagnosis of IBD. PMID:27101004

    This systematic review was undertaken to determine the extent to which adult subjects representing sex (female), race (nonwhite), and age (>50 years) categories are included in clinical studies of HIV curative interventions and thus, by extension, the potential for data to be analyzed that may shed light on the influence of such demographic variables on safety and/or efficacy. English-language publications retrieved from PubMed and from references of retrieved papers describing clinical studies of curative interventions were read and demographic, recruitment year, and intervention-type details were noted.

    Abstract This systematic review was undertaken to determine the extent to which adult subjects representing sex (female), race (nonwhite), and age (>50 years) categories are included in clinical studies of HIV curative interventions and thus, by extension, the potential for data to be analyzed that may shed light on the influence of such demographic variables on safety and/or efficacy. English-language publications retrieved from PubMed and from references of retrieved papers describing clinical studies of curative interventions were read and demographic, recruitment year, and intervention-type details were noted. Variables of interest included participation by sex, age, and race; changes in participation rates by recruitment year; and differences in participation by intervention type. Of 151 publications, 23% reported full demographic data of study enrollees, and only 6% reported conducting efficacy analyses by demographic variables. Included studies recruited participants from 1991 to 2011. No study conducted safety analyses by demographic variables. The representation of women, older people, and nonwhites did not reflect national or international burdens of HIV infection. Participation of demographic subgroups differed by intervention type and study location. Rates of participation of demographic groups of interest did not vary with time. Limited data suggest efficacy, particularly of early therapy initiation followed by treatment interruption, may vary by demographic variables, in this case sex. More data are needed to determine associations between demographic characteristics and safety/efficacy of curative interventions. Studies should be powered to conduct such analyses and cure-relevant measures should be standardized. PMID:25313793

    Objective To examine the association of current cigarette smoking and pack-years smoked to the incidence and progression of age-related macular degeneration (AMD) and to examine the interactions of current smoking and pack-years smoked with Complement Factor H (CFH, rs1061170) and Age-Related Maculopathy Susceptibility 2 (ARMS2, rs10490924) genotype. Design A longitudinal population-based study of AMD in a representative American community. Examinations were performed every 5 years over a 20-year period. Participants 4439 participants in the population-based Beaver Dam Eye Study. Methods AMD status was determined from grading retinal photographs. Multi-state models were used to model the relationship of current smoking and pack-years smoked and interactions with CFH and ARMS2 to the incidence and progression of AMD over the entire age range. Main Outcome Measures Incidence and progression of AMD over a 20-year period and interactions between current smoking and pack-years smoked with CFH and ARMS2 genotype. Results The incidence of early AMD over the 20-year period was 24.4% and the incidence of late AMD was 4.5%. Current smoking was associated with an increased risk of transitioning from minimal to moderate early AMD. A greater number of pack-years smoked was associated with an increased risk of transitioning from no AMD to minimal early AMD and from severe early AMD to late AMD. Current smoking and a greater number of pack-years smoked were associated with an increased risk of death. There were no statistically significant multiplicative interactions between current smoking or pack-years smoked and CFH or ARMS2 genotype. Conclusions Current smoking and a greater number of pack-years smoked increase the risk of the progression of AMD. This has important health care implications because smoking is a modifiable behavior. PMID:24953792

    Background: According to drug gateway theory, smoking cigarettes, especially, low onset age of smoking, is one of the risk factors for future use. Objectives: The present study aimed to compare nicotine and opiate addicts to identify the differences in personality traits and onset age of smoking in the two groups that cause some individuals to appeal to other substances after starting to use cigarettes. Patients and Methods: Two groups of opiate and nicotine addicts were randomly selected. Revised version of the Cloninger temperament inventory questionnaire, the Fagrastrom nicotine dependence and the Maudsley addiction profile were used. ANOVA and logistic regression were applied for data analysis. Results: Opiate addicts had higher scores in novelty seeking dimension and lower scores in cooperativeness compared to nicotine addicts. The onset age of smoking cigarette in opiate addicts was lower than nicotine addicts. Conclusions: Low onset age of smoking cigarettes, high novelty seeking and low cooperativeness in opiate dependents are among the important personality traits in future use of drugs that can predict the subsequent onset of using opiate drugs.

    The study of 3,472 chest x-rays from four populations with different levels of exposure to asbestos and with different cigarette smoking histories shows that smoking in the general population does not produce pulmonary fibrosis recognizable on chest radiography. In the general population of Michigan, the prevalence of a radiographic pattern of fibrosis was 0.5 percent in men and 0.0 percent in women. In a Long Beach, California census tract population, the prevalences were 3.7 percent for men and 0.6 percent for women. Similarly, cigarette smoking does not enhance fibrosis when the exposure to asbestos has been as light as that in households of shipyard workers. Asbestosis was recognized in 6.6 percent of 137 shipyard workers' wives who have never smoked and 7.6 percent of 132 who had ever smoked. Cigarette smoking and asbestos appear to be synergistic in those occupationally exposed to asbestos (as insulators), since 7.2 percent of 97 nonsmokers and 20.5 percent of 316 ever-smokers showed fibrosis. This apparent synergy was also found in shipyard workers up to age 70 with 31 percent of nonsmokers and 43.3 percent of ever-smokers having fibrosis. There were increases of approximately 10 percent in the prevalence of fibrosis in cigarette smokers and nonsmokers for each decade after age 40.

    Background It is generally accepted that smoking starts in adolescence and earlier initiation is associated with more negative health outcomes. Some research suggests that women initiate smoking at later ages and have more negative health outcomes than men. The purpose of this study was to examine gender differences in age of initiation and its association with health. Methods The sample included men (n=8,506) and women (n=8,479) with a history of smoking from the 2001-2002 National Epidemiological Survey of Alcohol Related Conditions. Logistic regression was used to examine gender differences in the effect of late smoking initiation on physical and mental health status after adjusting for covariates. Results At mostly all ages after 16, women exceeded men in rates of smoking initiation (59.8% vs. 50.3%, p<.001). Among late initiators (≥16), women were more likely than men to have hypertension (OR:1.24,CI:1.09-1.41), heart disease (OR:1.20,CI:1.00-1.45), major depressive disorder (OR:2.54,CI:2.22-2.92) and generalized anxiety disorder (OR:2.34,CI:1.84-2.99). Among early initiators (<16), women were more likely than men to have major depressive disorder (OR:2.42,CI:2.11-2.77) and generalized anxiety disorder (OR:2.01,CI:1.59-2.54) but there were no gender differences in the likelihood of having hypertension (OR:1.04,CI:0.89-1.22) and heart disease (OR:1.11,CI:0.90-1.36). Conclusions In late adolescence and adulthood, women exceed men in smoking initiation. Late initiation was associated with more significant physical health risks for women than men. Our findings raise questions about generally accepted notions on the age at which smoking initiation occurs and its association with health.

    The aims of this study were to determine the effect of age, sex and race distance on velocity (v), stroke rate (SR), stroke length (SL) and stroke index (SI) of subelite adolescent swimmers in competition, and to investigate their pacing strategies during the 100-m and 200-m events. Video footage of 112 adolescent swimmers (56 female; 56 male), competing in the 100-m and 200-m freestyle events, in two age groups (12-14; 15-18 years) was recorded and subsequently analyzed. A MANOVA showed that all stroke parameters significantly differed between sexes and between race distances. The older adolescents had a higher v, a longer SL and a greater SI (p < .01) than the younger adolescents. There were significant interaction effects between age and sex for v, SL and SI. Most adolescents had a SL that was within 7% of that reported for 1992 Olympians, but had up to 16% lower SRs. Separate Friedman's ANOVAs showed that SL differed between successive race quarters for both age groups, both sexes and both race distances. It is likely that physical immaturity, inexperience in competition pacing and within-race fatigue strongly influence the performances of subelite adolescent front crawl swimmers. PMID:25902554

    Previous studies have reported mixed results regarding the association between age at menarche and environmental tobacco smoke exposure, both prenatally and during early childhood; however, few studies have had data available during both time periods. The present study examined whether exposure to prenatal tobacco smoke (PTS) via maternal smoking during pregnancy or childhood environmental tobacco smoke (ETS) was associated with age at menarche in a multi-ethnic birth cohort. With the uniquely available prospectively collected data on body size and growth at birth and in early life, we further examined whether the association between PTS and ETS exposure and age at menarche was mediated by these variables. From 2001 to 2006, we recruited 262 women born between 1959 and 1963 who were enrolled previously in a New York City site of the National Collaborative Perinatal Project. Mothers who smoked during pregnancy vs. those who did not were more likely to be White, younger, have more education and have lower birthweight babies. Daughters with heavy PTS exposure (≥ 20 cigarettes per day) had a later age at menarche (>12 years vs. ≤ 12 years), odds ratio (OR) =2.1 [95% confidence interval (CI) 0.9, 5.0] compared with daughters with no PTS. Daughters exposed to only childhood ETS had a later age at menarche, OR=2.1 [95% CI 1.0, 4.3], and those exposed to PTS and ETS combined had a statistically significant later age at menarche, OR=2.2 [95% CI 1.1, 4.6] compared with daughters with no PTS and no ETS. These results did not change after further adjustment for birthweight and postnatal growth suggesting that exposure to PTS and ETS is associated with later age at menarche even after considering possible relationships with growth.

    2007-05-25

    Breathing secondhand smoke (SHS) causes heart disease and lung cancer in adults and increased risks for sudden infant death syndrome, acute respiratory infections, middle-ear disease, worsened asthma, respiratory symptoms, and slowed lung growth in children. No risk-free level of exposure to SHS exists. The Global Youth Tobacco Survey (GYTS), initiated in 1999 by the World Health Organization (WHO), the Canadian Public Health Association, and CDC includes questions related to tobacco use, including exposure to SHS. This report examines data collected from 137 jurisdictions (i.e., countries and territories) during 2000-2007, presents estimates of exposure to SHS at home and in places other than the home among students aged 13-15 years who had never smoked, and examines the association between exposure to SHS and susceptibility to initiating smoking. GYTS data indicated that nearly half of never smokers were exposed to SHS at home (46.8%), and a similar percentage were exposed in places other than the home (47.8%). Never smokers exposed to SHS at home were 1.4-2.1 times more likely to be susceptible to initiating smoking than those not exposed. Students exposed to SHS in places other than the home were 1.3-1.8 times more likely to be susceptible to initiating smoking than those not exposed. As part of their comprehensive tobacco-control programs, countries should take measures to create smoke-free environments in all indoor public places and workplaces. PMID:17522587

    Attitudes and self-reported practices for smoking cessation counseling among 145 providers at a health maintenance organization were compared among two provider groups, physicians/nurse practitioners and registered/licensed practical nurses, and across three patient age groups, < 50, 50-64, and > or = 65. Smoking cessation attitudes did not differ by provider type but they did differ by patient age, especially among the registered/licensed practical nurses, whose attitudes were least favorable for the oldest smokers (> or = 65). While smoking cessation practices did not differ by patient age, they did differ by provider type. Self-reported performance of the 4 As of smoking cessation practice (Ask, Advise, Assist, Arrange) was more frequent among the physicians/nurse practitioners than among the registered/licensed practical nurses. However, among both groups, asking and advising practices were reported more often than were assisting and arranging. In all cases, different attitudes were correlated with different practice behaviors for the two provider groups. Also, there were more significant correlations between age-specific attitudes and practices among the registered/licensed practical nurses than among the physicians/nurse practitioners. This was true especially regarding the oldest patients. The findings suggest a need for provider education, especially among registered/licensed practical nurses, about the benefits of smoking cessation for patients of all ages and the potential effectiveness of provider-based intervention strategies that are targeted toward specific age groups. The findings also suggest that assisting and arranging practices in particular need improvement among all types of providers. PMID:7597023

  8. Racial resentment and smoking.

    Racial resentment (also known as symbolic racism) is among the most widely tested measures of contemporary prejudice in political science and social psychological research over the past thirty years. Proponents argue that racial resentment reflects anti-black emotion obtained through pre-adult socialization. In light of affect-based models of substance use, this paper examined the association between racial resentment and smoking in a national sample of non-Hispanic white, black, and Hispanic respondents. Data come from the 2012 American National Election Study, which contained two measures of smoking. The results of ordinal logistic regression models indicate a positive association between racial resentment and smoking among non-Hispanic whites (N = 2133) that is not present among blacks (N = 693) or Hispanics (N = 660). Models controlled for age, education, income, gender, political ideology, region, and mode of interview. Furthermore, analyses indicated that a measure of race-related affect, admiration and sympathy towards blacks, partially mediated the association between racial resentment and smoking. For non-Hispanic whites, racial resentment appears to constitute a risk factor for smoking. Future studies should further specify the conditions linking substance use to the race-related affective component of racial resentment. PMID:25562312

    We take advantage of the May 1998 biomass burning event in Southern Mexico to test the global applicability of a smoke aerosol size model developed from data observed in South America. The Mexican event is an unique opportunity to observe well-aged, residual smoke. Observations of smoke aerosol size distribution made from vertical profiles of airborne in situ measurements show an inverse relationship between concentration and particle size that suggests the aging process continues more than a week after the smoke is separated from its fire sources. The ground-based radiometer retrievals show that the column-averaged, aged, Mexican smoke particles are larger (diameter = 0.28 - 0.33 micrometers) than the mean smoke particles in South America (diameter = 0.22 - 0.30 micrometers). However, the difference (delta - 0.06 micrometer) translates into differences in backscattering coefficient of only 4-7% and an increase of direct radiative forcing of only 10%.

    The aim of this study was to assess the effects of short exposures to experimentally aged cigarette smoke on the nose and upper airways. This crossover study compared the effects of 30-min exposures to (1) experimentally aged cigarette smoke at 1 mg/m³ particulate matter (PM)/14 ppm carbon monoxide (CO) and (2) conditioned filtered air on urinary metabolites of nicotine and tobacco-specific nitrosamines. Subjective nasal symptoms were assessed by questionnaire, objective nasal congestion was assessed by anterior rhinomanometry and nasal nitric oxide (NO) concentrations were determined. Experimentally aged cigarette smoke is a validated model for secondhand smoke (SHS). Twenty-six healthy nonsmokers (10 normal, 7 atopic/nonrhinitic, 7 atopic rhinitic, 2 nonatopic/rhinitic) were studied. A 30-min exposure to SHS increased nasal resistance in healthy nonsmokers. The rise in nasal resistance was most pronounced in rhinitic subjects. Significant increases were not noted when atopic subjects were considered independent of rhinitis status. Secondhand smoke exposure also elevated subjective nasal symptoms and urinary concentrations of metabolites of nicotine (cotinine and trans-3´-hydroxycotinine) and tobacco-specific nitrosamines [(4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL)] in all subgroups of subjects. Exposure-related, subjective nasal symptoms were significantly higher in rhinitic than in normal subjects. Significant changes in nasal NO concentrations were not detected. Data indicate a 30-min exposure to secondhand smoke at 1 mg/m³ PM increases subjective upper respiratory symptoms, increases urinary cotinine and NNAL, and produces objective nasal airflow obstruction in human subjects.

    This study examined the relationship between conscientiousness and mortality over 18 years and whether smoking behavior mediated this relationship. We utilized data from the Veterans Affairs Normative Aging Study on 1349 men who completed the Goldberg (1992) adjectival markers of the Big Five. Over the 18-year follow-up, 547 (41%) participants died. Through proportional hazards modeling in a structural equation modeling framework, we found that higher levels of conscientiousness significantly predicted longer life, and that this effect was mediated by current smoking status at baseline. Methodologically, we also demonstrate the effectiveness of using a structural equation modeling framework to evaluate mediation when using a censored outcome such as mortality. PMID:23504043

  12. Methods of suicide by age: sex and race differences among the young and old.

    McIntosh, J L; Santos, J F

    The elderly have the highest suicide rate in the United States. In partial explanation of this finding, a common statement in the suicide literature is that older persons tend to use more drastic and effective methods of suicide. However, little, if any, data have been presented in defense of this explanation. In order to investigate the validity of this contention, annual official statistics for specific methods of suicide (firearms, hanging, poisons) by age for different sex and racial groups (whites, blacks, nonwhites excluding black) were examined from 1960 to 1978. Comparisons among the age-sex-race groups, along with trends over time and differences in the methods employed, were noted. For white males, blacks of both sexes, and nonwhites excluding black females, the findings confirmed the use of more violent methods by the elderly than by the young in terms of the proportion of suicides by firearms and/or hanging. Less support and, in fact, opposite results for method-related age differences were obtained for white females and nonwhites excluding black males. Another general finding was an increase in the use of firearms for most of the groups studied. The need for data for specific groups within the nonwhite category excluding blacks is apparent both from the available literature and from the present findings. Possible explanations and implications of the observed results are discussed. PMID:3830918

    Background Given their early age of diagnosis, young breast cancer (BC) survivors face issues that differ widely from their older counterparts. Patients and Methods We mailed a survey to 2209 patients who were ≤45 years at time of BC diagnosis. Each survey was comprised of: the Quality of Life in Adult Cancer Survivors instrument, Menopause Symptom Scale, and questions aimed at obtaining pertinent background information. Results 1090 patients completed the survey. Mean age at time of diagnosis was 39.5 years; median years from diagnosis was 6.6 years. Distress related to vaginal dryness (p=0.0002) and pain from intercourse (p=0.0014) was significantly higher in patients who were <5 years from diagnosis, compared to those >10 years from diagnosis. In the area of financial problems, black women had greater distress than white women (p=0.0010). Compared to white women, Hispanic women had worse family distress scores (p=0.0028) and summary cancer specific scores (p=0.0076). Patients >10 years from diagnosis had poorer sexual interest (p=0.003) than women who were closer to diagnosis. Women ≥40 years at diagnosis had significantly lower sexual interest (p=0.0016) than women <40 years. Stage and neoadjuvant chemotherapy did not have a significant effect on QOL. Conclusion Even in comparison to stage and neoadjuvant chemotherapy, race, age at diagnosis, and time from diagnosis have significant long term effects on QOL following BC treatment. PMID:24461458

    Objective We evaluated the short-term effects of smoking cessation therapy with varenicline on the lung function. Methods In this study, 81 subjects received 12 weeks of smoking cessation therapy with varenicline. No changes were made to any previously prescribed medications. A physical examination, blood sampling, and spirometry were performed at the first and last visit. Spirometric lung ages were calculated by a formula based on height and the forced expiratory volume in 1 second. The success group comprised 62 subjects who attained 4-week continuous abstinence confirmed by exhaled carbon monoxide testing; whereas the failure group comprised 19 subjects who did not attain this result. However, the number of cigarettes consumed per day was reduced in all subjects of the failure group. Results The spirometric lung ages significantly improved over the 12-week period in the success group (69.8±24.7 vs. 66.9±24.1, p<0.01); however, spirometric lung ages significantly deteriorated in the failure group (70.5±25.5 vs. 73.7±26.9, p<0.01). The effect sizes (Cohen's d) of spirometric lung age in the success and failure groups were 0.37 and 0.81, respectively. The post-hoc statistical power of the spirometric lung age in the success and failure groups was 0.83 and 0.91, respectively. According to a multiple regression analysis, success in smoking cessation exhibited an independent association with the difference in spirometric lung age between the last visit and baseline (p<0.01). Conclusion These findings suggest that successful smoking cessation therapy with varenicline improves the spirometric lung age in the short term. PMID:27580538

    Background: Cadmium is a ubiquitous environmental pollutant associated with increased risk of leading causes of mortality and morbidity in women, including breast cancer and osteoporosis. Iron deficiency increases absorption of dietary cadmium, rendering women, who tend to have lower iron stores than men, more susceptible to cadmium uptake. We used body iron, a measure that incorporates both serum ferritin and soluble transferrin receptor, as recommended by the World Health Organization, to evaluate the relationships between iron status and urine and blood cadmium. Methods: Serum ferritin, soluble transferrin receptor, urine and blood cadmium values in never-smoking, non-pregnant, non-lactating, non-menopausal women aged 20-49 years (n=599) were obtained from the 2003-2008 National Health and Nutrition Examination Surveys. Body iron was calculated from serum ferritin and soluble transferrin receptor, and iron deficiency defined as body iron <0 mg/kg. Robust linear regression was used to evaluate the relationships between body iron and blood and urine cadmium, adjusted for age, race, poverty, body mass index, and parity. Results: Per incremental (mg/kg) increase in body iron, urine cadmium decreased by 0.003 {mu}g/g creatinine and blood cadmium decreased by 0.014 {mu}g/L. Iron deficiency was associated with 0.044 {mu}g/g creatinine greater urine cadmium (95% CI=0.020, 0.069) and 0.162 {mu}g/L greater blood cadmium (95% CI=0.132, 0.193). Conclusions: Iron deficiency is a risk factor for increased blood and urine cadmium among never-smoking, pre-menopausal, non-pregnant US women, independent of age, race, poverty, body mass index and parity. Expanding programs to detect and correct iron deficiency among non-pregnant women merits consideration as a potential means to reduce the risk of cadmium associated diseases. - Highlights: {yields} Body iron was calculated from serum ferritin and soluble transferrin receptor. {yields} Body iron was inversely associated with blood

    Adolescent sports participants are less likely to smoke cigarettes, and sports participation may prevent young people from smoking. Research suggests that the relationship between sports participation and smoking may vary by race/ethnicity and is also possibly moderated by exposure to peer smoking. We investigated these relationships in a sample of 311 adolescents ages 13 – 21 presenting for well-visit medical appointments. Participants completed valid assessments of demographics, sports participation, exposure to peer smoking, and smoking behavior. The primary outcome was smoking status (never smoked, tried smoking, experimental/current smoker). Ordinal logistic regression was used separately for non-Hispanic White (n = 122) and non-White (n = 189; 70.4% Black, 14.3% Hispanic, and 15.3% other) adolescents. Among White adolescents, sports participants had significantly lower odds of smoking than non-sports participants, independent of age, gender, and peer smoking. For non-Whites, the adjusted effect of sports participation on smoking depended upon exposure to peers who smoke. Compared with non-sport participants with no exposure to peer smoking, sports participants with no exposure to peer smoking had significantly lower odds of smoking, whereas sports participants with exposure to peer smoking had significantly higher odds of smoking. Sports appear to be protective against smoking among non-Hispanic White adolescents, but among non-White adolescents exposure to peer smoking influences this protection. Interventions incorporating sports to prevent smoking should consider these racial/ethnic differences to address disparities in smoking-related disease. PMID:22698897

    Background Half of pregnancies in the United States are unintended, with the highest proportions occurring among Blacks, Hispanics, and teenagers. Understanding differences in knowledge and attitudes about contraception by race/ethnicity and age can improve efforts to reduce disparities in unintended pregnancy. Methods This analysis used data from the 897 female respondents in National Survey of Reproductive and Contraceptive Knowledge, a survey exploring young adults' knowledge and attitudes about contraception and pregnancy. Bivariate and multivariate logistic regression analyses were used to assess racial/ethnic and age group differences in knowledge and attitudes about contraceptives. Findings Hispanics and teenagers (aged 18–19) had lower awareness of available contraceptive methods, and lower knowledge about individual methods compared with White women and young adults (age 20–29). For example, Hispanics (74%) and teenagers (77%) were less likely to have heard of the intrauterine device (IUD) than were White women (90%) and young adults (90%), and were less likely to know that a woman experiencing side effects could switch brands of oral contraceptive pills (72% of Hispanics vs. 86% of White women; 76% of teenagers vs. 90% of young adults). Hispanics born outside the United States had lower knowledge about contraceptives than U.S.-born Hispanics. For example, foreign-born Hispanics were less likely than U.S.-born Hispanics to have heard of the IUD (59% vs. 82%) or the vaginal ring (55% vs. 95%). Conclusions Lower contraceptive knowledge among teenagers and Hispanics, particularly immigrants, suggests the importance of disseminating family planning information to these women as one means to address disparities in unintended pregnancy.

    Background: Recognition of the predisposing factors of bladder cancer is very important and provides possible prevention measures. The aim of this study was to investigate the types, distribution of bladder tumors and their relationship with opium consumption and smoking in patients who referred to Shahid Beheshti Hospital, Babol, Iran. Methods: In this case-control study, all patients diagnosed with bladder cancer who underwent surgery during 2001-2012 were enrolled. The subjects of the control group were selected among the patients who underwent ERCP (endoscopic retrograde cholangiopancreatography) for gallstone and had no tumors and genitourinary problems. Data regarding demographic, pathology reports and tumor type, smoking status, history of opium consumption and its duration were collected. Patients and controls were compared using t-test and chi-square test. SPSS software Version 20 was used for analysis. Results: In this study, 175 patients with an average age of 63.30±15.29 years and 175 age- matched controls were studied. A significant association was observed between smoking and opium consumption with bladder cancer (P=0.001 for both). Conclusion: The results of this study showed that opium consumption and smoking are associated with bladder cancer PMID:26221505

    An index that assesses the multidimensional components of the diet across the lifecycle is useful in describing diet quality. The purpose of this study was to use the Healthy Eating Index-2005, a measure of diet quality in terms of conformance to the 2005 Dietary Guidelines for Americans, to describe the diet quality of Americans by varying sociodemographic characteristics in order to provide insight as to where diets need to improve. The Healthy Eating Index-2005 scores were estimated using 1 day of dietary intake data provided by participants in the 2003-2004 National Health and Nutrition Examination Survey. Mean daily intakes of foods and nutrients, expressed per 1,000 kilocalories, were estimated using the population ratio method and compared with standards that reflect the 2005 Dietary Guidelines for Americans. Participants included 3,286 children (2 to 17 years), 3,690 young and middle-aged adults (18 to 64 years), and 1,296 older adults (65+ years). Results are reported as percentages of maximum scores and tested for significant differences (P ≤ 0.05) by age, sex, race/ethnicity, income, and education levels. Children and older adults had better-quality diets than younger and middle-aged adults; women had better-quality diets than men; Hispanics had better-quality diets than blacks and whites; and diet quality of adults, but not children, generally improved with income level, except for sodium. The diets of Americans, regardless of socioeconomic status, are far from optimal. Problematic dietary patterns were found among all sociodemographic groups. Major improvements in the nutritional health of the American public can be made by improving eating patterns. PMID:23168270

    The prevalence of Class 3 obesity (BMI ≥40 kg/m(2)) has more than doubled in the past 25 years. In a 14-year prospective study from age 10 to 24 of a biracial schoolgirl cohort (293 black, 256 white), we assessed childhood correlates of Class 3 BMI at age 24. Of 42 girls with Class 3 BMI at age 24, 36 (86%) were black. By logistic regression, significant explanatory variables of Class 3 BMI at age 24 included top decile waist circumference at age 11 (odds ratio (OR) 5.7, 95% confidence interval (CI) 2.3-13.9, P = 0.0002), age 10 BMI ≥ the Center for Disease Control (CDC) 2000 top 15% (OR 7.0, 95% CI 2.5-19.3, P = 0.0002), and a three-way interaction between race, childhood insulin, and average caloric intake from age 10 to age 19 (for each unit increase, OR 1.7 95% CI 1.3-2.2, P = 0.0003). Age 10 BMI, age 11 waist circumference, and interaction of race, childhood insulin, and childhood caloric intake predict Class 3 obesity in young adulthood, facilitating childhood identification of girls at high risk for developing Class 3 obesity.

    Background The fastest Ironman race times in ‘Ironman Hawaii’ were achieved in very recent years. This study investigated the change in sex difference in both race performance and the age of peak performance across years in the top ten athletes for split disciplines and overall race time in the ‘Ironman Hawaii’ between 1983 and 2012. Methods Changes in split times, overall race times, and age of athletes across years for the top ten overall and the fastest swimmers, cyclists, and runners were investigated using regression analyses and analyses of variance. Results Between 1983 and 2012, the overall top ten men and women finishers improved their swimming (only men), cycling, running, and overall race times. The sex difference in overall race time decreased significantly (p = 0.01) from 15.2% to 11.3% across time. For the split disciplines, the sex difference remained unchanged (p > 0.05) for swimming (12.5 ± 3.7%) and cycling (12.5 ± 2.7%) but decreased for running from 13.5 ± 8.1% to 7.3 ± 2.9% (p = 0.03). The time performance of the top ten swimmers remained stable (p > 0.05), while those of the top ten cyclists and top ten runners improved (p < 0.01). The sex difference in performance remained unchanged (p > 0.05) in swimming (8.0 ± 2.4%), cycling (12.7 ± 1.8%), and running (15.2 ± 3.0%). Between 1983 and 2012, the age of the overall top ten finishers and the fastest swimmers, cyclists, and runners increased across years for both women and men (p < 0.01). Conclusions To summarize, for the overall top ten finishers, the sex difference decreased across years for overall race time and running, but not for swimming and cycling. For the top ten per discipline, the sex difference in performance remained unchanged. The athletes improved their performances across years although the age of peak performance increased.

    Growing evidence indicates that parental smoking is associated with risk of offspring obesity. The purpose of this study was to identify whether parental tobacco smoking during gestation was associated with risk of diabetes mellitus. This is a prospective study of 44- to 54-year-old daughters (n = 1801) born in the Child Health and Development Studies pregnancy cohort between 1959 and 1967. Their mothers resided near Oakland California, were members of the Kaiser Foundation Health Plan and reported parental tobacco smoking during an early pregnancy interview. Daughters reported physician diagnoses of diabetes mellitus and provided blood samples for hemoglobin A1C measurement. Prenatal maternal smoking had a stronger association with daughters' diabetes mellitus risk than prenatal paternal smoking, and the former persisted after adjustment for parental race, diabetes and employment (aRR = 2.4 [95% confidence intervals 1.4-4.1] P < 0.01 and aRR = 1.7 [95% confidence intervals 1.0-3.0] P = 0.05, respectively). Estimates of the effect of parental smoking were unchanged when further adjusted by daughters' birth weight or current body mass index (BMI). Maternal smoking was also significantly associated with self-reported type 2 diabetes diagnosis (2.3 [95% confidence intervals 1.0-5.0] P < 0.05). Having parents who smoked during pregnancy was associated with an increased risk of diabetes mellitus among adult daughters, independent of known risk factors, providing further evidence that prenatal environmental chemical exposures independent of birth weight and current BMI may contribute to adult diabetes mellitus. While other studies seek to confirm our results, caution toward tobacco smoking by or proximal to pregnant women is warranted in diabetes mellitus prevention efforts. PMID:25665487

    This report presents projections of the resident population for the 50 states and the District of Columbia by age, sex, and race for 1988-2010. These projections are the 1st to be produced by single years of age for individual calendar years. They are also the 1st to use an enhanced methodology that incorporates the annual state-to-state flows of migrants from matched tax returns together with the demographic detail from the Current Population Survey and decennial census. Some highlights of the data follow. 1) The South and West will continue to be the fastest growing regions in the US. By 2010, the South will still be the most populous region, increasing its share of the total population to over 37%, while the West will become the 2nd most populous region with over 23% of the population. 21% of the population will reside in the Midwest, while about 19% will reside in the Northeast. 2) California is projected to remain the most populous state for the next 25 years, followed by New York (until 1990, when Texas pushes it to 3rd), Florida, and Illinois (by the year 2000). 3) Of the 4 regions in 1986 and 1990, the Northeast will have the highest proportion of its population in the 65 or over age group. It will also have the lowest proportion in the younger groups, under 5 and 5-17. The West will have a higher proportion of its population in the youngest age group and a lower proportion in the oldest group. 4) During the last decade of this century, the numbers of children under age 5 are projected to decline by 1.5 million, while the numbers of school-age children will increase by over 3 million. By 2000, the Northeast will still have the oldest age distribution, while the West will continue to have the youngest. 5) Between 2000 and 2010, the numbers of children under age 5 are projected to remain constant in the US, while declining in the Northeast and Midwest and increasing in the South and West. By 2010, the Northeast, Midwest, and South all will have approximately

    We characterize here a new nationwide incident cohort of multiple sclerosis from the US military-veteran population. This cohort provides an update to the only other US nationwide incidence study of multiple sclerosis performed during the 1970s. Medical records and data from the Department of Defense and Department of Veterans Affairs for cases of multiple sclerosis who served in the military between 1990, the start of the Gulf War era, and 2007 and who were service-connected for this disorder by the Department of Veterans Affairs from 1990 on, were reviewed. A total of 2691 patients were confirmed as having multiple sclerosis: 2288 definite, 190 possible, 207 clinically isolated syndrome and six neuromyelitis optica. Overall racial categories were White, Black and other, which included all Hispanics. There were 1278 White males and 556 females; 360 Black males and 296 females; and 200 others, 153 (77%) of whom were Hispanic. Mean age at onset of 30.7 years did not differ significantly by race or sex. Age at onset was 17-50 years in 99%, the same age range as 99% of the military. Average annual age specific (age 17-50 years) incidence rates per 100 000 for the entire series were 9.6 with 95% confidence interval of 9.3-10.0. Rates for Blacks were highest at 12.1 with confidence interval 11.2-13.1, Whites were 9.3 (interval 8.9-9.8) and others 6.9 (interval 6.0-7.9). For 83 Hispanics defined for 2000-07, the rate was 8.2 (interval 6.5-10.1). Much smaller numbers gave rates of 3.3 for Asian/Pacific Islanders and 3.1 for native Americans. Rates by sex for Whites were 7.3 and 25.8 male and female, respectively, for Blacks 8.4 and 26.3, and for Hispanics 6.6 and 17.0. Rates by service were high for Air Force (10.9) and Army (10.6), medium for Navy (9.1) and Coast Guard (7.9), and low for Marines (5.3). Relative risk of multiple sclerosis was 3.39 female:male and 1.27 Black:White. These new findings indicate that females of all races now have incidence rates for multiple

    Background Epithelial lining fluid plays a critical role in protecting the lung from oxidative stress, in which the oxidised status may change by ageing, smoking history, and pulmonary emphysema. Methods Bronchoalveolar lavage (BAL) was performed on 109 young and older subjects with various smoking histories. The protein carbonyls, total and oxidised glutathione were examined in BAL fluid. Results By Western blot analysis, the major carbonylated protein in the BAL fluid was sized at 68 kDa, corresponding to albumin. The amount of carbonylated albumin per mg total albumin in BAL fluid was four times higher in older current smokers and three times higher in older former smokers than in age matched non‐smokers (p<0.0001, p = 0.0003, respectively), but not in young smokers. Total glutathione in BAL fluid was significantly increased both in young (p = 0.006) and older current smokers (p = 0.0003) compared with age matched non‐smokers. In contrast, the ratio of oxidised to total glutathione was significantly raised (72%) only in older current smokers compared with the other groups. There was no significant difference in these parameters between older smokers with and without mild emphysema. Conclusions Oxidised glutathione associated with excessive protein carbonylation accumulates in the lung of older smokers with long term smoking histories even in the absence of lung diseases, but they are not significantly enhanced in smokers with mild emphysema.

    Pain assessment is subject to bias due to characteristics of the individual in pain and of the observing person. Few research studies have examined pain assessment biases in an experimental setting. The present study employs innovative virtual human technology to achieve greater experimental control. A lens model design was used to capture decision-making policies at the idiographic and nomothetic level. Seventy-five undergraduates viewed virtual humans (VH) that varied in sex, race, age, and pain expression. Participants provided computerized ratings with Visual Analogue Scales on the VH's pain intensity, pain unpleasantness, negative mood, coping, and need for medical treatment. Idiographic analyses revealed that individuals used pain expression most frequently as a significant cue. Nomothetic analyses showed that higher pain expression VH and female VH were viewed as having higher pain intensity, higher pain unpleasantness, greater negative mood, worse coping, and a greater need to seek medical treatment than lower pain expression VH and male VH, respectively. Older VH were viewed as having worse coping and a greater need to seek medical treatment than younger VH. This innovative paradigm involving VH technology and a lens model design was shown to be highly effective and could serve as a model for future studies investigating pain-related decision making in healthcare providers.

    Examination of the literature for hprt mutant frequencies from peripheral T cells yielded data from 1194 human subjects. Relationships between mutant frequency, age, sex, and smoking were examined, and the kinetics were described. Mutant frequency increases rapidly with age until about age 15. Afterward, the rate of increase falls such that after age 53, the hprt mutant frequency is largely stabilized. Sex had no effect on mutant frequency. Cigarette smoking increased mean mutant frequency compared to nonsmokers, but did not alter age vs. mutant frequency relationships. An hprt in vivo mutant database containing 795 human hprt mutants from 342 individuals was prepared. No difference in mutational spectra was observed comparing smokers to nonsmokers, confirming previous reports. Sex affected the frequency of deletions (>1 bp) that are recovered more than twice as frequently in females (P = 0. 008) compared to males. There is no indication of a significant shift in mutational spectra with age for individuals older than 19 yr, with the exception of A:T --> C:G transversions. These events are recovered more frequently in older individuals. PMID:10388825

    Age-related cataract formation is the primary cause of blindness worldwide and although treatable by surgical removal of the lens the majority of sufferers have neither the finances nor access to the medical facilities required. Therefore, a better understanding of the pathogenesis of cataract may identify new therapeutic targets to prevent or slow its progression. Cataract incidence is strongly correlated with age and cigarette smoking, factors that are often associated with accumulation of metal ions in other tissues. Therefore this study evaluated the age-related changes in 14 metal ions in 32 post mortem human lenses without known cataract from donors of 11 to 82 years of age by inductively coupled plasma mass spectrometry; smoking-related changes in 10 smokers verses 14 non-smokers were also analysed. A significant age-related increase in selenium and decrease in copper ions was observed for the first time in the lens tissue, where cadmium ion levels were also increased as has been seen previously. Aluminium and vanadium ions were found to be increased in smokers compared to non-smokers (an analysis that has only been carried out before in lenses with cataract). These changes in metal ions, i.e. that occur as a consequence of normal ageing and of smoking, could contribute to cataract formation via induction of oxidative stress pathways, modulation of extracellular matrix structure/function and cellular toxicity. Thus, this study has identified novel changes in metal ions in human lens that could potentially drive the pathology of cataract formation. PMID:26794210

    Background Passive smoking unfavorably affects pregnancy, child birth and child health. Passive smoking associates with still-birth, premature birth as well as acute respiratory infection, asthma, disorder in red blood cell metabolism in children. This study examined the effects of passive smoking on anemia in young children in Jordan. Methods The analysis based on the information from 740 children aged 0–35 months that were tested for hemoglobin levels included in the 2002 Jordan Population and Family Health Survey. This study used multivariate logistic regression method to analyze the effect of passive smoking on anemia in young children in Jordan, controlling for a number of risk factors and confounding factors for anemia. Results Results indicated that independent of other risk factors and confounding factors, anemia in young children was strongly positively associated with exposure to passive smoking from both parents (OR= 2.99, p < 0.01). Severely undernourished children were at higher risk of anemia independent of passive smoking and other risk factors (OR= 5.29, p < 0.05). Children age 24–35 months, children born to mothers age 35–49, and children lived in households with a hygienic toilet facility were less likely to suffer from anemia. Conclusion Passive smoking from both parents was strongly positively associated with anemia in young children in Jordan independent of other risk factors and confounding factors. The results support the importance of smoking prevention during and after pregnancy that prevent childhood anemia and others morbidities in young children. PMID:17425780

    Background and aims Cross-sectional studies suggest that Obstructive Lung Disease (OLD) and smoking affect lean mass and mobility. We aimed to investigate whether OLD and smoking accelerate aging-related decline in lean mass and physical functioning. Methods 260 persons with OLD (FEV1 63±18 %predicted), 157 smoking controls (FEV1 95±16 %predicted), 866 formerly smoking controls (FEV1 100±16 %predicted) and 891 never-smoking controls (FEV1 104±17 %predicted) participating in the Health, Aging and Body Composition (ABC) Study were studied. At baseline, the mean age was 74±3 y and participants reported no functional limitations. Baseline and seven-year longitudinal data were investigated of body composition (by Dual-energy X-ray absorptiometry), muscle strength (by hand and leg dynamometry) and Short Physical Performance Battery (SPPB). Results Compared to never-smoking controls, OLD persons and smoking controls had a significantly lower weight, fat mass, lean mass and bone mineral content (BMC) at baseline (p<0.05). While the loss of weight, fat mass, lean mass and strength was comparable between OLD persons and never-smoking controls, the SPPB declined 0.12 points/yr faster in OLD men (p=0.01) and BMC 4 g/yr faster in OLD women (p=0.02). In smoking controls, only lean mass declined 0.1 kg/yr faster in women (p=0.03) and BMC 8 g/yr faster in men (p=0.02) compared to never-smoking controls. Conclusions Initially well-functioning older adults with mild-to-moderate OLD and smokers without OLD have a comparable compromised baseline profile of body composition and physical functioning, while seven-year longitudinal trajectories are to a large extent comparable to those observed in never-smokers without OLD. This suggests a common insult earlier in life related to smoking. 3 PMID:21724748

    Exposure to tobacco pollutants that linger indoors after smoking has taken place ( thirdhand smoke, THS) can occur over extended periods and is modulated by chemical processes involving atmospheric reactive species. This study investigates the role of ozone and indoor surfaces in chemical transformations of tobacco smoke residues. Gas and particle constituents of secondhand smoke (SHS) as well as sorbed SHS on chamber internal walls and model materials (cotton, paper, and gypsum wallboard) were characterized during aging. After smoldering 10 cigarettes in a 24-m 3 room size chamber, gas-phase nicotine was rapidly removed by sorption to chamber surfaces, and subsequently re-emitted during ventilation with clean air to a level of ˜10% that during the smoking phase. During chamber ventilation in the presence of ozone (180 ppb), ozone decayed at a rate of 5.6 h -1 and coincided with a factor of 5 less nicotine sorbed to wallboard. In the presence of ozone, no gas phase nicotine was detected as a result of re-emission, and higher concentrations of nicotine oxidation products were observed than when ventilation was performed with ozone-free air. Analysis of the model surfaces showed that heterogeneous nicotine-ozone reaction was faster on paper than cotton, and both were faster than on wallboard. However, wallboard played a dominant role in ozone-initiated reaction in the chamber due to its large total geometric surface area and sink potential compared to the other substrates. This study is the first to show in a room-sized environmental chamber that the heterogeneous ozone chemistry of sorbed nicotine generates THS constituents of concern, as observed previously in bench-top studies. In addition to the main oxidation products (cotinine, myosmine and N-methyl formamide), nicotine-1-oxide was detected for the first time.

    Objectives. We examined associations between parental and adolescent smoking and nicotine dependence in the United States. Methods. We used data from the 2004 to 2012 National Survey on Drug Use and Health, which ascertained smoking behaviors of 1 parent and 1 adolescent aged 12 to 17 years in 35 000 dyads. We estimated associations between parental and adolescent smoking behaviors, adjusted for covariates. Results. Parental current dependence was strongly associated with adolescents’ lifetime smoking (adjusted odds ratio [AOR] = 2.96; 95% confidence interval [CI] = 2.47, 3.55), whereas parental current nondependent smoking (AOR = 2.26; 95% CI = 1.92, 2.67) and former smoking (AOR = 1.51; 95% CI = 1.31, 1.75) were less strongly associated. Only parental nicotine dependence was associated with adolescent nicotine dependence (AOR = 1.66; 95% CI = 1.00, 2.74). Associations between parental and adolescent smoking did not differ by race/ethnicity. Parents’ education, marital status, and parenting and adolescents' mental health, beliefs about smoking, perception of schoolmates’ smoking, and other substance use predicted adolescent smoking and dependence. Conclusions. Reducing parental smoking would reduce adolescent smoking. Prevention efforts should encourage parental smoking cessation, improve parenting, address adolescent mental health, and reinforce adolescents' negative beliefs about smoking. PMID:26378847

    Study objective Recognition of the health consequences of exposure to environmental tobacco smoke has led government agencies and many employers to establish policies that restrict cigarette smoking in public and workplaces. This cross sectional study examines the association of workplace smoking policies and home smoking restrictions with current smoking among women. Design Participants were employed US women ages 18–64 who were self respondents to the 1998–1999 or 2000–2001 tobacco use supplement to the current population survey supplements. Cross tabulations and multivariate logistic regression analyses examine the association of selected demographic characteristics, occupation, income, workplace and home smoking policies/restrictions with current smoking, consumption patterns, and quit attempts among women by poverty level for five race/ethnic groups. Main results The prevalence of either having an official workplace or home smoking policy that completely banned smoking increased with increased distance from the poverty level threshold. A complete ban on home smoking was more frequently reported by African American and Hispanic women although Hispanic women less frequently reported an official workplace smoking policy. In general, policies that permitted smoking in the work area or at home were associated with a higher prevalence of current smoking but this varied by poverty level and race/ethnicity. Home smoking policies that permitted smoking were associated with lower adjusted odds of having a least one quit attempt for nearly all poverty level categories but there was no association between having one quit attempt and workplace policies. Conclusion Home smoking policies were more consistently associated with a lower prevalence of current smoking irrespective of poverty status or race/ethnicity than workplace policies. These findings underscore the importance of examining tobacco control policies in multiple domains (work and home) as well as by race

    Introduction: Maternal nicotine use during pregnancy has a negative impact on the child. Numerous studies have demonstrated an association between smoking during pregnancy and psychological deficits. This study looks at deficits in executive functioning in preschool-aged children. Methods: The executive functioning of preschool children was assessed by asking parents to complete the parental form of the Behavior Rating Inventory of Executive Functions – Preschool Version (BRIEF-P, German version). The results for preschool children whose mothers had smoked during pregnancy (n = 71) were compared with those of a control group. In a subsample, parental assessments of children of smokers (n = 42) and non-smokers (n = 27) were complemented by the teacher form of the BRIEF-P (German version), which allowed inter-rater agreement (parents vs. preschool teachers) to be assessed. Results: An increased incidence of executive function deficits was noted in the children of smokers, based on parental assessment. Clinically relevant deficits were particularly evident with regard to inhibition, with inhibitory deficits in children of smokers found to be almost four times higher than in the control group (p = 0.006). Inhibitory deficits were reported both by parents and by preschool teachers. Discussion: The increased percentage of executive function deficits described here, particularly the increased inhibitory deficits, confirms the current state of research on smoking during pregnancy. Poor inhibition or impulse control is a key symptom of ADHD. PMID:25684788

    This paper examines how race and ancestry are taken up in gene-environment interaction (GEI) research on complex diseases such as heart disease, diabetes, and cancer. Using 54 in-depth interviews of 33 scientists and over 200 hours of observation at scientific conferences, we explore how GEI researchers use and interpret race, ethnicity, and ancestry in their work. We find that the use of self-identified race and ethnicity (SIRE) exists alongside ancestry informative markers (AIMs) to ascertain genetic ancestry. Our participants assess the utility of these two techniques in relative terms, downplaying the accuracy and value of SIRE compared to the precision and necessity of AIMs. In doing so, we argue that post-genomic scientists seeking to understand the interactions of genetic and environmental disease determinants actually undermine their ability to do so, by valorizing precise characterizations of individuals’ genetic ancestry over measurement of the social processes and relations that differentiate social groups.

    The Hanford Environmental Does Reconstruction (HEDR) Project was established to estimate radiation doses that people could have received from nuclear operations at the Hanford Site since 1944. To identify groups that may have received doses, population estimates containing age, race, and sex detail for ten counties in Washington and Oregon for the years 1940 to 1980 were prepared by the Demographics Laboratory under a subcontract with the Pacific Northwest Laboratory (PNL). A data base of population information was developed from census reports and published and unpublished collections from the Washington State Office of Financial Management and Center for Population Research. Three estimation methods were then explored: the cohort-component model, cohort interpolation, and age-group interpolation. The estimates generated through cohort and age-group interpolation are considered adequate for initial use in the HEDR Project. Results are presented in two forms: (1) county populations by sex and single year of age and (2) county populations by sex and race for age groupings. These results are made available to the HEDR Project for further refinement into population estimates by county census divisions.

    The aim is to study the trends of cigarette smoking from 2001 to 2012 using a California representative sample in the US. Data was taken from the California Health Interview Survey (CHIS) from 2001 to 2012, which is a population-based, biennial, random digit-dial telephone survey of the non-institutionalized population. The CHIS is the largest telephone survey in California and the largest state health survey in the US. 282,931 adults (n = 184,454 with age 18-60 and n = 98,477 with age >60) were included in the analysis. Data were weighted to be representative and adjusted for potential covariance and non-response biases. During 2001-2012, the prevalence of current smoking decreased from 18.86 to 15.4 % among adults age 18-60 (β = -0.8, p = 0.0041). As for adults age >60, the prevalence of current smoking trend decreased with variations, started from 9.66 % in 2001, slightly increased to 9.74 % in 2003, but then gradually decreased, falling to 8.18 % in 2012. In 2012, there was a 14 % reduction of daily smoking adults age 18-60 (OR 0.84, 95 % CI 0.76-0.93, p = 0.0006) compared to 2001, while no significant reduction of daily smoking was observed for those age >60. The reductions of smoking prevalence for adults younger than 60 are encouraging. However, there is a concern for smoking cessation rates among those older than 60 years of age, particularly for African Americans. PMID:25929677

    Aims The developmental origins of health and disease hypothesis states that later-life disease may be influenced by the quality of the in utero environment. Environmental toxicants can have detrimental effects on fetal development, potentially through effects on placental development and function. Maternal smoking during pregnancy is associated with low birth weight, preterm birth and other complications, and exposure to cigarette smoke in utero has been linked to gross pathologic and molecular changes to the placenta, including differential DNA methylation in placental tissue. The aim of this study was to investigate the relationship between maternal smoking during pregnancy, methylation changes in the placenta and gestational age. Materials & methods We used Illumina®’s (CA, USA) Human Methylation27 BeadChip technology platform to investigate the methylation status of 21,551 autosomal, non-SNP-associated CpG loci in DNA extracted from 206 human placentas and examined loci whose variation in methylation was associated with maternal smoking during pregnancy. Results We found that methylation patterns of a number of loci within the RUNX3 gene were significantly associated with smoking during pregnancy, and one of these loci was associated with decreased gestational age (p = 0.04). Conclusion Our findings, demonstrating maternal smoking-induced changes in DNA methylation at specific loci, suggest a mechanism by which in utero tobacco smoke exposure could exert its detrimental effects upon the health of the fetus.

    BACKGROUND Smoking is a well-known risk factor for peripheral arterial disease (PAD). Data regarding differences in the prevalence of PAD between sexes are somewhat controversial. In addition, most studies indicate that the prevalence of PAD increases with age in both sexes. In the present study, the effects of sex, age and smoking on the ankle-brachial index (ABI) in a Finnish cardiovascular risk population were investigated. OBJECTIVES To investigate the relationship between the ankle-brachial index, and age, sex and smoking in a Finnish population at risk for cardiovascular disease. METHODS All men and women between 45 and 70 years of age living in a rural town (Harjavalta, Finland; total population 7700) were invited to participate in a population survey (Harmonica study). Patients with previously diagnosed diabetes or vascular disease were excluded. In total, 2856 patients were invited to participate in the study. From these subjects, a cardiovascular risk population was screened. Complete data were available from 1028 persons. ABI (the ratio between the posterior tibial or dorsalis pedis artery and brachial artery pressures) was measured, and questionnaires were used to detect smoking status and relevant medical history. Only current smoking status was taken into account. RESULTS The mean ABI for the entire study population was 1.10 (range 0.56 to 1.64). Current smokers had a lower mean ABI (1.06; P<0.001). There was no statistically significant difference in ABI values among age groups, although the majority of patients with ABI values below 0.9 were older than 60 years of age. There was no statistically significant difference in ABI between sexes. CONCLUSION As previously reported, the present study shows the significant effect of smoking in the development of PAD. No statistically significant difference was found among age groups, but the tendency was toward lower ABIs in the oldest age groups. Sex had a minimal effect on the ABI. PMID:22477327

    In early adjuvant breast cancer trial reports, aromatase inhibitors more effectively reduced breast recurrence with lower risk of thromboembolic events and endometrial cancer than tamoxifen, while aromatase inhibitors had higher fracture and cardiovascular disease risk. We used data from updated patient-level meta-analyses of adjuvant trials in analyses to summarize the benefits and risks of these agents in various clinical circumstances. Baseline incidence rates for health outcomes by age and race/ethnicity, absent aromatase inhibitor, or tamoxifen use were estimated from the Women's Health Initiative. Aromatase inhibitor and tamoxifen effects on distant recurrence were obtained from a meta-analysis of the Arimidex, Tamoxifen, Alone or in Combination (ATAC) and Breast International Group (Big-1-98) clinical trials. Impact on other health outcomes were obtained from meta-analyses of randomized trials comparing aromatase inhibitor to tamoxifen use and from placebo-controlled chemoprevention trials. All health outcomes were given equal weight when modeling net benefit/risk for aromatase inhibitor compared to tamoxifen use by breast cancer recurrence risk, age (decade), race/ethnicity, hysterectomy (yes/no), and by prior myocardial infarction. Over a 10-year period, the benefit/risk index was more favorable for aromatase inhibitor than for tamoxifen as adjuvant breast cancer therapy in almost all circumstances regardless of patient age, race/ethnicity, breast cancer recurrence risk, or presence or absence of a uterus. Only in older women with prior myocardial infarction and low recurrence risk was an advantage for tamoxifen seen. Using a benefit/risk index for endocrine adjuvant breast cancer therapy in postmenopausal women, benefit was higher for aromatase inhibitor use in almost all circumstances. PMID:26602222

    We sought to determine whether parenting, sibling and peer influences are associated with offspring ever smoking, regular smoking and nicotine dependence (ND) after controlling for familial factors. We used a twin-family design and data from structured diagnostic surveys of 1919 biological offspring (ages 12-32 years), 1107 twin fathers, and 1023 mothers. Offspring were classified into one of four familial risk groups based on twin fathers' and their co-twins' history of DSM-III-R nicotine dependence. Multivariate multinomial logistic regression was used to model familial risk, paternal and maternal parenting behavior and substance use, sibling substance use, and friend and school peer smoking, alcohol and drug use. Ever smoking was associated with increasing offspring age, white race, high maternal pressure to succeed in school, sibling drug use, and friend smoking, alcohol and drug use. Offspring regular smoking was associated with these same factors with additional contribution from maternal ND. Offspring ND was associated with increasing offspring age, male gender, biological parents divorce, high genetic risk from father and mother ND, maternal problem drinking, maternal rule inconsistency and sibling drug use, and friend smoking, alcohol and drug use. Friend smoking had the largest magnitude of association with offspring smoking. This effect remains after accounting for familial liability and numerous parent and sibling level effects. Smoking interventions may have greatest impact by targeting smoking prevention among peer groups in adolescent and young adult populations. PMID:22094168

    A total of 865 members of the U.S. military underwent repair of Achilles tendon ruptures at U.S. military hospitals during calendar years 1994, 1995, and 1996. The discharge summaries of these patients were analyzed for patient demographic information, including age, race, and causative activity. Patients were then stratified by age, race, and cause of injury. Blacks were at increased risk for undergoing repair of the Achilles tendon compared with nonblacks (overall relative risk = 4.15, 95% confidence interval [CI] = 3.63, 4.74; summary odds ratio controlling for age = 3.69, CI = 3.25, 4.19). Participation in the game of basketball accounted for 64.9% of all injuries in black patients and 34.0% of all injuries in nonblack patients. Among those injured, blacks had a significantly increased risk for injury related to playing basketball than nonblacks (relative risk = 1.82, CI = 1.58, 2.10). This finding suggests that there may be other predisposing factor(s) that result in a higher risk of Achilles tendon ruptures in black individuals. PMID:10628159

    Summary Recent work suggests that leukocyte telomere length (LTL), a marker of cellular aging, is sensitive to effects of social stress and may also provide early indication of premature aging. Using data from a birth cohort with LTL information at birth and in middle adulthood we examined a potential source of race-based health disparity by testing the hypothesis that Blacks would demonstrate a faster rate of telomere shortening than Whites. Linear regression analyses were conducted and adjusted for pack years, BMI, education and social factors, diet, exercise, marital status, and age. At birth black individuals had LTLs that were longer, on average, than their White counterparts (b = 3.85, p < 0.01). However, rate of shortening was greater for Blacks, who showed a larger difference in length between birth and adulthood (b = 5.10, p = 0.01) as compared with Whites, resulting in smaller racial differences in absolute adult LTL.

    Purpose. We examine early-onset cigarette smoking and how, if at all, it is related to subsequent smoking practices. Methods. From 2004 to 2007, face-to-face interviews were conducted with 485 adult cigarette smokers residing in the Atlanta metropolitan area. Data analysis involved a multivariate analysis to determine whether age of smoking onset was related to current smoking practices when the effects of gender, age, race, marital/relationship status, income, and educational attainment were taken into account. Results. The mean age for smoking onset was 14.8, and more than one-half of all smokers had their first cigarette between the ages of 12 and 16. Most people reported an interval of less than one month between their first and second time using tobacco. Earlier onset cigarette smoking was related to more cigarette use and worse tobacco-related health outcomes in adulthood. Conclusions. Early prevention and intervention are needed to avoid early-onset smoking behaviors. Intervening after initial experimentation but before patterned smoking practices are established will be challenging, as the interval between initial and subsequent use tends to be short.

    Purpose. Despite the increasing popularity of marathon running, there are no data on the responses of stroke volume (SV) and cardiac output (CO) to exercise in this context. We sought to establish whether marathon performance is associated with the ability to sustain high fractional use of maximal SV and CO (i.e, cardiac endurance) and/or CO, per meter (i.e., cardiac cost). Methods. We measured the SV, heart rate (HR), CO, and running speed of 14 recreational runners in an incremental, maximal laboratory test and then during a real marathon race (mean performance: 3 hr 30 min ± 45 min). Results. Our data revealed that HR, SV and CO were all in a high but submaximal steady state during the marathon (87.0 ± 1.6%, 77.2 ± 2.6%, and 68.7 ± 2.8% of maximal values, respectively). Marathon performance was inversely correlated with an upward drift in the CO/speed ratio (mL of CO × m−1) (r = −0.65, P < 0.01) and positively correlated with the runner's ability to complete the race at a high percentage of the speed at maximal SV (r = 0.83, P < 0.0002). Conclusion. Our results showed that marathon performance is inversely correlated with cardiac cost and positively correlated with cardiac endurance. The CO response could be a benchmark for race performance in recreational marathon runners. PMID:22645458

    Particulate emissions from wildfires impact human health and have a large but uncertain effect on climate. Modelling schemes depend on information about emission factors, emitted particle microphysical and optical properties and ageing effects, while satellite retrieval algorithms make use of characteristic aerosol models to improve retrieval. Ground-based remote sensing provides detailed aerosol characterisation, but does not contain information on source. Here, a method is presented to estimate plume origin land cover type and age for AERONET aerosol observations, employing trajectory modelling using the HYSPLIT model, and satellite active fire and aerosol optical thickness (AOT) observations from Moderate Resolution Imaging Spectroradiometer (MODIS) and Along Track Scanning Radiometer (AATSR). It is applied to AERONET stations located in or near northern temperate and boreal forests for the period 2002-2013. The results from 629 fire attributions indicate significant differences in size distributions and particle optical properties between different land cover types and plume age. Smallest fine mode median radius (Rfv) are attributed to plumes from cropland and/or natural vegetation mosaic (0.143 μm) and grassland (0.157 μm) fires. North American evergreen needleleaf forest emissions show a significantly smaller Rfv (0.164 μm) than plumes from Eurasian mixed forests (0.193 μm) and plumes attributed to the land cover types with sparse tree cover - open shrubland (0.185 μm) and woody savannas (0.184 μm). The differences in size distributions are related to inferred variability in plume concentrations between the land cover types. Significant differences are observed between day and night emissions, with daytime emissions showing larger particle sizes. Smoke is predominantly scattering for all of the classes with median single scattering albedo at 440 nm (SSA(440)) values close to 0

    Introduction 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. Methods 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. Results 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. Conclusions 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.

    Fluorescence in situ hybridization with chromosome-specific composite DNA probes (``chromosome painting``) is a reliable and efficient method for detecting structural chromosome aberrations. Painting is now being used to quantify chromosome damage in many human populations. In one such study we evaluated 91 unexposed people ranging in age from birth (cord bloods) to 79. We established a baseline frequency of stable aberrations that showed a highly significant curvi-linear increase with age (p < 0.00001) that accounted for 70% of the variance between donors. The magnitude of this effect illustrates the importance of understanding the cytogenetic changes that occur with age, which is particularly important for quantifying the effects of prior adverse environmental, occupational, or accidental exposure. In this paper we use the data obtained in our previous study to characterize the distribution of stable aberrations by age and pack-years of cigarette smoking. We also provide estimates of the number of cell equivalents that need to be scored to detect a given increase in aberrations above the background level surveyed in this population.

    This report describes a collaborative study conducted in Montreal, Canada, Portland, Ore., and Winnipeg, Canada, to establish the relationship between the single-breath N2 test and age, sex, and smoking and to determine the prevalence of functional abnormalities in these populations. In nonsmokers, age-related regressions for closing volume, closing capacity, and the slope of phase III obtained from the single-breath N2 test, plus the ratio of the I-s forced expiratory volume to the forced vital capacity had very similar slopes, suggesting that differences in geographic location, climate, air pollution, and occupation had no effect on lung function detectable by these tests. Among the 6 city/six groups there was no systematic difference in the prevalence of functional abnormalities between the cities, but closing capacity expressed as a percentage of total lung capacity was abnormal most often in men and the slope of the alveolar plateau was abnormal most often in women. The prevalence of respiratory symptoms within different smoking categories was similar in the 3 cities. Although the number of cigarettes smoked had a significant effect on every test except the ratio of the I-s forced expiratory volume to forced vital capacity in men, the effect of age was considerably greater than the effect of smoking, and the dose-response relationship was weak. We conclude that additional factors may interact with smoking to place a smoker at risk of developing chronic airflow limitation. PMID:475152

    Background A variety of tobacco control interventions have become available in Japan over the past decade, however, the magnitude to which they have impacted on smoking rates may have varied by socioeconomic status such as job content, particularly for middle-aged men who were formerly long-term smokers. We conducted a longitudinal study to investigate the differences between smoking cessation strategies among a national sample of middle-aged Japanese employed men between 2005 and 2010. Methods Data was extracted from a previous longitudinal survey of middle-aged and elderly people that had been conducted by the Ministry of Health, Labour and Welfare. In 2005, 16,738 Japanese men aged 50–59 years were recruited and sent a questionnaire in each year of the study. We analyzed data for individuals who reported being current smokers at baseline. Cox’s discrete time proportional hazard regression analysis was used to examine potential associations between smoking cessation and socioeconomic factors. Results Of the 6187 employed, male smokers who participated in 2005, 31% subsequently quit smoking during the 5-year follow-up period. Those working in manufacturing, transportation, or security were less likely to have quit smoking than those working in management. Having no marital partner, never having been married, or those experiencing psychological distress were significantly less likely to have quit smoking during this time. Conclusions Although almost one-third of middle-aged, male smokers quit their habit between 2005 and 2010; the uptake of this national strategy appears to have been far from uniform across Japanese society. Socioeconomic factors such as occupation, marital status and psychological distress were negatively correlated with quitting, suggesting that these groups should be more aggressively targeted in further interventions.

    Back trajectories suggest that an elevated absorbing aerosol plume observed over Oklahoma in May 2003 can be traced to intense forest fires in Siberia two weeks earlier. The Fire Locating and Modeling of Burning Emissions (FLAMBE) product is used to estimate smoke emissions from those fires. The Model for Integrated Research on Atmospheric Model Exchanges (MIRAGE) is used to simulate the transport, aging, radiative properties, and removal of the aerosol. The simulated aerosol optical depth is compared with satellite retrievals, and the vertical structure of the plume is compared with in situ measurements. Sensitivity experiments are performed to determine the sensitivity of the simulated plume to uncertainty in the emissions vertical profile, mass flux, size distribution, and composition.

    Objective To compare macular choroidal thickness between cigarette smokers, those with a history of smoking, and nonsmokers in patients over 65 years of age with early-atrophic age-related macular degeneration (AMD) and normals. Methods Prospective, consecutive, observational case series. Enhanced depth imaging spectral domain optical coherence tomography 12-line radial scans were performed and choroidal thickness manually quantified at 84 points in the central 3 mm of the macula. Data of normals, soft drusen alone, and soft drusen with additional features of early AMD were compared. A multivariate analysis of variance (MANOVA) model, controlling for age, was constructed to evaluate the effect of smoking history and AMD features on choroidal thickness. Results A history of smoking was significantly associated with a thinner choroid across all patients via logistic regression (P=0.004; O.R.=12.4). Mean macular choroidal thickness was thinner for smokers (148±63 μm) than for nonsmokers (181±65 μm) among all diagnosis categories (P=0.003). Subgroup analysis of patients with AMD features revealed a similar decreased choroidal thickness in smokers (121±41 μm) compared with nonsmokers (146±46 μm, P=0.006). Bivariate analysis revealed an association between increased pack-years of smoking and a thin choroid across all patients (P<0.001) and among patients with features of early AMD (P<0.001). Both the presence of features of macular degeneration (P<0.001) and a history of smoking (P=0.024) were associated with decreased choroidal thickness in a MANOVA model. Conclusion Chronic cigarette smoke exposure may be associated with decreased choroidal thickness. There may be an anatomic sequelae to chronic tobacco smoke exposure that underlies previously reported AMD risk. PMID:24833184

    The prevalence of cigarette smoking among HIV+ individuals is greater than that found in the general population. However, factors related to smoking within this population are not well understood. This study examined the associations between smoking and demographic, medical, substance use, and psychosocial factors in a clinic-based sample of HIV+ men and women. Two hundred twelve participants completed self-report measures of tobacco use, HIV-related symptoms, viral load, CD4, alcohol and illicit drug use, depression, and social support. Multinomial logistic regression analyses modeled the independent associations of the cross-sectional set of predictors with smoking status. Results indicated that 74% of the sample smoked at least one cigarette per day; using standard definitions, 23% of the sample were light smokers, 22% were moderate smokers, and 29% smoked heavily. Smoking was associated with more HIV-related symptoms, greater alcohol and marijuana use, and less social support. Light smoking was related to minority race/ethnicity and less income; moderate smoking was associated with less education; and heavy smoking was related to less education and younger age. Viral load, CD4 count, and depression were not associated with smoking status. Psychosocial interventions targeting this population should consider the relationships between biopsychosocial factors and smoking behavior. PMID:17570050

    Background: Vitamin A is an essential nutrient during pregnancy and throughout the lifecycle due to its role in the development of critical organ systems. Because maternal tissue is progressively depleted of vitamin A to supply fetal demands, women who become pregnant while possessing marginal vitamin A reserves are at increased risk of vitamin A inadequacy as pregnancy progresses. Few studies have assessed the relationship between socioeconomic factors and retinol status in women of childbearing age. Methods: We used the National Health and Nutrition Examination Survey (NHANES) to assess the relationship between serum retinol concentrations and socioeconomic factors in women of childbearing age. Women 14–45 years of age (n = 3170) from NHANES cycles 2003–2004 and 2005–2006 were included. Serum retinol concentrations were divided into categories according to World Health Organization criteria. All statistical procedures accounted for the weighted data and complex design of the NHANES sample. A p-value of < 0.05 was considered statistically significant. Results: The poverty score and race were significantly associated with vitamin A status after adjustment for confounders. Odds of retinol concentrations of <1.05 µmol/L were 1.85 times higher for those of lower socioeconomic status when compared to those of higher status (95% CI: 1.12–3.03, p = 0.02), and 3.1 times higher for non-Hispanic blacks when compared to non-Hispanic whites (95% CI: 1.50–6.41, p = 0.002). Dietary intakes of retinol activity equivalents were significantly lower in groups with higher poverty scores (p = 0.004). Conclusion There appear to be disparities in serum vitamin A levels in women of childbearing age related to income and race in the United States. PMID:27548213

    HIV care cascades can evaluate programmatic success over time. However, methodologies for estimating cascade stages vary, and few have evaluated differences by demographic subgroups. We examined cascade performance over time and by age, sex, and race/ethnicity in Kaiser Permanente, providing HIV care in eight US states and Washington, DC. We created cascades for HIV+ members' age ≥13 for 2010-2012. We measured "linkage" (a visit/CD4 within 90 days of being diagnosed for new patients; ≥1 medical visit/year if established); "retention" (≥2 medical visits ≥60 days apart); filled ART (filled ≥3 months of combination ART); and viral suppression (HIV RNA <200 copies/mL last measured in year). The cascades were stratified by calendar year, sex, age, and race/ethnicity. We found men had statistically (p < 0.05) higher percent linkage, filled ART, and viral suppression for 2010 and 2011 but not for 2012. Women had significantly greater retention for all years. Annually, older age was associated (p < 0.05) with retention, filled ART, and viral suppression but not linkage. Latinos had greater (p < 0.05) retention than whites or blacks in all years, with similar retention comparing blacks and whites. Filled ART and viral suppression was increased (p < 0.05) for whites compared with all racial/ethnic groups in all years. Cascade methodology requiring success at upstream stages before measuring success at later stages (i.e., "dependent" methodology) underreported performance by up to 20% compared with evaluating each stage separately ("independent"). Thus, care results improved over time, but significant differences exist by patient demographics. Specifically, retention efforts should be targeted toward younger patients and blacks; women, blacks, and Latinos require greater ART prescribing. PMID:26505968

    Lung function was evaluated in a representative population sample of 50-year-0ld men living in one Swedish city. Twenty-four smoking and 15 non-smoking men heterozygous for alpha1-antitrypsin deficiency--that is, with the protease-inhibitor (Pi1 phenotype MZ--were carefully matched for weight and smoking habit with Pi M controls. The pulmonary function of non-smoking Pi MZ subjects did not differ from that of non-smoking Pi M controls. In contrast, smoking heterozygotes showed a significant loss of elastic recoil, enlarged residual volumes, and increased closing capacity but no signs of obstructive ventilatory impairment. Most smoking Pi MZ individuals reported mild exertional dyspnoea. PMID:303135

    We used data from a Scandinavian prospective multicenter study to investigate if smoking in pregnancy may have an adverse effect on the child's mental and motor abilities. Eligible for enrolment were para I and 2 women with a singleton pregnancy, who resided in one of the study areas and could be registered before the 20th gestational week. Women were classified as 'smokers' or 'non-smokers' at study start. At 13 months, 376 children (124 children of smokers) were evaluated with the Bayley Scales of Infant Development. At this age, children of smokers and non-smokers performed equally well. At 5 years, 369 children (132 children of smokers) were tested with the Wechsler Preschool and Primary Scales of Intelligence Revised (WPPSI-R), and 362 children with the Peabody Developmental Motor Scales (PDMS). Children of smokers had an increased risk of getting a WPPSI-R score below the median value of the population (OR = 2.1, 95% CI: 1.2-3.3), but the risk was reduced when we adjusted for maternal education (OR = 1.6, 95% CI: 0.9-3.7). Children of smokers had an increased risk of getting a test score below the median population value on the subscale 'balance' from PDMS (OR = 1.8, 95% CI: 1.2-2.8). Thus, we found that smoking in pregnancy was associated with a small, but demonstrable adverse effect on the child's balance at 5 years, whereas the negative effect on cognitive function did not reach statistical significance, when we adjusted for the mother's level of education.

    Exposure to particles from combustion of wood is associated with respiratory symptoms, whereas there is limited knowledge about systemic effects. We investigated effects on systemic inflammation, oxidative stress and DNA damage in humans who lived in a reconstructed Viking Age house, with indoor combustion of wood for heating and cooking. The subjects were exposed to high indoor concentrations of PM2.5 (700-3,600 µg/m(3)), CO (10.7-15.3 ppm) and NO2 (140-154 µg/m(3)) during a 1-week stay. Nevertheless, there were unaltered levels of genotoxicity, determined as DNA strand breaks and formamidopyrimidine DNA glycosylase and oxoguanine DNA glycosylase 1 sensitive sites in peripheral blood mononuclear cells. There were also unaltered expression levels of OGG1, HMOX1, CCL2, IL8, and TNF levels in leukocytes. In serum, there were unaltered levels of C-reactive protein, IL6, IL8, TNF, lactate dehydrogenase, cholesterol, triglycerides, and high-density lipoproteins. The wood smoke exposure was associated with decreased serum levels of sICAM-1, and a tendency to decreased sVCAM-1 levels. There was a minor increase in the levels of circulating monocytes expressing CD31, whereas there were unaltered expression levels of CD11b, CD49d, and CD62L on monocytes after the stay in the house. In conclusion, even a high inhalation exposure to wood smoke was associated with limited systemic effects on markers of oxidative stress, DNA damage, inflammation, and monocyte activation.

    Particulate emissions from wildfires impact human health and have a large but uncertain effect on climate. Modelling schemes depend on information about emission factors, emitted particle microphysical and optical properties and ageing effects, while satellite retrieval algorithms make use of characteristic aerosol models to improve retrieval. Ground based remote sensing provides detailed aerosol characterisation, but does not contain information on source. A new method is presented to estimate plume origin land cover type and age for AERONET aerosol observations, employing trajectory modelling using the HYSPLIT model, and satellite active fire and aerosol optical thickness (AOT) observations from MODIS and AATSR. It is applied to AERONET stations located in or near Northern temperate and boreal forests, for the period 2002-2013. The results from 629 fire attributions indicate significant differences insize distributions and particle optical properties between different land cover types. Smallest fine mode median radius are attributed to plumes from cropland/natural vegetation mosaic (0.143 μm) and grasslands (0.147 μm) fires. Evergreen needleleaf forest emissions show a significantly smaller fine mode median radius (0.164 μm) than plumes from woody savannas (0.184 μm) and mixed forest (0.193 μm) fires. Smoke plumes are predominantly scattering for all of the classes with median single scattering albedo at 440 nm (SSA(440)) values close to 0.95 except the cropland emissions which have SSA(440) value of 0.9. Overall fine mode volume median radius increase rate is 0.0095μm per day for the first 4 days of ageing and 0.0084 μm per day for seven days of ageing. Changes in size were consistent with a decrease in Angstrom Exponent and increase in Asymmetry parameter. No significant changes in SSA(λ) with ageing were found.

    The aim of this study was to estimate the prevalence and identify correlates of second-hand tobacco smoke (SHS) among 6,412 current non-smoking school-going adolescents (aged 11 to 18 years) in South Africa. A cross-sectional study was carried out in 2008 in South Africa within the framework of the Global Youth Tobacco Survey. Overall, 25.7% of students were exposed to SHS at home, 34.2% outside of the home and 18.3% were exposed to SHS at home and outside of the home. Parental and close friends smoking status, allowing someone to smoke around you and perception that passive smoking was harmful were significant determinants of adolescent's exposure to both SHS at home and outside of the home. Identified factors can inform the implementation of public health interventions in order to reduce passive smoking among adolescents. PMID:22016702

    Background Black adolescents see more substance use in mainstream media but seem less responsive to it than other U.S. adolescents. Black-oriented media may be more personally relevant to them. Purpose To determine smoking exposure separately for black-oriented (BSME) and mainstream (MMSE) movies and assess their longitudinal relationships with smoking among black and other-race adolescents. Methods Two-wave (2007–2009) national cohort survey of 2341 nonsmoking (at baseline) U.S. adolescents (aged 13–19 years), analyzed in 2012. The surveys determined BMSE and MMSE based on respondents’ exposure to random subsets of 50 movies from a contemporary sample of 95 black-oriented and 288 mainstream movies previously content-coded for smoking. Outcome was smoking initiation. Results Black teens had significantly more BMSE and MMSE than other teens (p’s <0.001). At follow-up, 23.5% of black and 29.0% of nonblack respondents had tried smoking. Among black respondents, BMSE was related to smoking initiation at follow-up but MMSE was not. For other adolescents, both BMSE and MMSE were related to smoking initiation. Conclusions A prospective relationship was found between exposure to smoking in movies and smoking initiation. Among black adolescents in the U.S., this was only for black-oriented movies, suggesting the importance of personal relevance of the exposures. Parents, practitioners, and producers should be aware of these potential influences of media on black teen viewers. PMID:23498099

    Current US federal dietary guidance recommends regular consumption of seafood (fish + shellfish) to promote health; however, little is known about how well Americans meet the guideline, particularly population subgroups that may be at risk for inadequate intake. The purposes of this study were to describe the prevalence of seafood consumption and, among consumers, the amounts of seafood eaten by sex, age group, income and education level, and race-ethnicity. Data from 15,407 adults aged 19+ participating in the 2005–2010 National Health and Nutrition Examination Surveys were analyzed using methods to account for sporadic intake of seafood. Over 80% of Americans reported consuming any seafood over the past 30 days, 74% reported consuming fish, and 54% reported eating shellfish. The percentages varied by socio-demographic group. Younger age and lower income and education levels were associated with lower odds of being a seafood consumer (p < 0.0001). Among those who reported eating seafood, the average amount eaten of any seafood was 158.2 ± 5.6 g/week. Among seafood consumers, women and individuals of lower age and education levels consumed less seafood. Approximately 80%–90% of seafood consumers did not meet seafood recommendations when needs were estimated by energy requirements. A great deal of work remains to move Americans toward seafood consumption at current recommended levels. PMID:25533013

    Background To investigate the relationship of human semen parameters with season, age and smoking status. Methods The present study used data from subjects recruited into an ongoing cross-sectional study on the relationship between environmental agents and semen characteristics. Our population consisted of 306 patients who presented to the Vincent Memorial Andrology Laboratory of Massachusetts General Hospital for semen evaluation. Sperm concentration and motility were measured with computer aided sperm analysis (CASA). Sperm morphology was scored using Tygerberg Kruger strict criteria. Regression analyses were used to investigate the relationships between semen parameters and season, age and smoking status, adjusting for abstinence interval. Results Sperm concentration in the spring was significantly higher than in winter, fall and summer (p < 0.05). There was suggestive evidence of higher sperm motility and percent of sperm with normal morphology in the spring than in the other seasons. There were no statistically significant relationships between semen parameters and smoking status, though current smokers tended to have lower sperm concentration. We also did not find a statistically significant relationship between age and semen parameters. Conclusions We found seasonal variations in sperm concentration and suggestive evidence of seasonal variation in sperm motility and percent sperm with normal morphology. Although smoking status was not a significant predictor of semen parameters, this may have been due to the small number of current smokers in the study. PMID:15507127

    The incarceration of criminal offenders in the United States has reached epidemic proportions. One way to scale back the prison population is by using empirical risk assessment methods to apportion prison sentences based on the likelihood of the offender recidivating, so-called "evidence-based sentencing." This practice has been denounced by some legal scholars, who claim that the use of certain empirically relevant risk factors-including gender, age, and race-is plainly immoral. This study tested whether lay individuals share their sentiment. More than 600 participants weighted to be representative of the United States population were asked about the extent to which they would support imposing shorter sentences for old versus young offenders, female versus male offenders, and white versus black offenders, all else being equal. The results indicate that very few participants (<3%) had no settled opinion about using evidence-based sentencing, and approximately half were unequivocally opposed to the practice. Whereas more than 3-quarters of participants were against using race to determine prison sentences, almost half were open to the possibility of using gender and more than 3-quarters of the participants were open to the possibility of using age to determine prison sentences. Individual differences as a function of participants' own demographic characteristics, or of their belief in "just deserts" as the primary purpose of sentencing, or of their political outlook, were either inconsistently or meagerly related to these findings. The profoundly disparate views held by the general public regarding the use of specific risk factors do not bode well for the use of demographic risk factors in sentencing as a way to roll back mass incarceration.

    Background Ovarian aging patterns differ between races, and appear to affect fertility treatment outcomes. What causes these differences is, however, unknown. Variations in ovarian aging patterns have recently been associated with specific ovarian genotypes and sub-genotypes of the FMR1 gene. We, therefore, attempted to determine differences in how functional ovarian reserve (FOR) changes with advancing age between races, and whether changes are associated with differences in distribution of ovarian genotypes and sub-genotypes of the FMR1 gene. Methods We determined in association with in vitro fertilization (IVF) FOR in 62 young Caucasian, African and Asian oocyte donors and 536 older infertility patients of all three races, based on follicle stimulating hormone (FSH), anti-Müllerian hormone (AMH) and oocyte yields, and investigated whether differences between races are associated with differences in distribution of FMR1 genotypes and sub-genotypes. Results Changes in distribution of mean FSH, AMH and oocyte yields between young donors and older infertility patients were significant (all P < 0.001). Donors did not demonstrate significant differences between races in AMH and FSH but demonstrated significant differences in oocyte yields [F(2,59) = 4.22, P = 0.019]: Specifically, African donors demonstrated larger oocyte yields than Caucasians (P = 0.008) and Asians (P = 0.022). In patients, AMH levels differed significantly between races [F (2,533) = 4.25, P = 0.015]. Holm-Sidak post-hoc comparisons demonstrated that Caucasians demonstrated lower AMH in comparison to Asians (P = 0.007). Percentages of FMR1 genotypes and sub-genotypes in patients varied significantly between races, with Asians demonstrating fewer het-norm/low sub-genotypes than Caucasians and Africans (P = 0.012). Conclusion FOR changes in different races at different rates, and appears to parallel ovarian FMR1 genotypes and sub-genotype distributions. Differences

    Background Cigarette smoking is widespread among HIV-infected patients, who confront increased risk of smoking-related co-morbidities. The effects of HIV infection and HIV-related variables on smoking and smoking cessation are incompletely understood. We investigated the correlates of smoking and quitting in an HIV-infected cohort using a validated natural language processor to determine smoking status. Method We developed and validated an algorithm using natural language processing (NLP) to ascertain smoking status from electronic health record data. The algorithm was applied to records for a cohort of 3487 HIV-infected from a large health care system in Boston, USA, and 9446 uninfected control patients matched 3:1 on age, gender, race and clinical encounters. NLP was used to identify and classify smoking-related portions of free-text notes. These classifications were combined into patient-year smoking status and used to classify patients as ever versus never smokers and current smokers versus non-smokers. Generalized linear models were used to assess associations of HIV with 3 outcomes, ever smoking, current smoking, and current smoking in analyses limited to ever smokers (persistent smoking), while adjusting for demographics, cardiovascular risk factors, and psychiatric illness. Analyses were repeated within the HIV cohort, with the addition of CD4 cell count and HIV viral load to assess associations of these HIV-related factors with the smoking outcomes. Results Using the natural language processing algorithm to assign annual smoking status yielded sensitivity of 92.4, specificity of 86.2, and AUC of 0.89 (95% confidence interval [CI] 0.88–0.91). Ever and current smoking were more common in HIV-infected patients than controls (54% vs. 44% and 42% vs. 30%, respectively, both P<0.001). In multivariate models HIV was independently associated with ever smoking (adjusted rate ratio [ARR] 1.18, 95% CI 1.13–1.24, P <0.001), current smoking (ARR 1.33, 95% CI 1.25

    A growing body of evidence indicates a strong association between smoking and depression. However, little is known about the possible effects of second-hand smoke (SHS) exposure on depression. This study aimed to examine the potential dose-response relation between SHS exposure and depressive symptoms among non-smoking middle-aged women. A cross-sectional survey was conducted using a stratified three-stage sampling method. Depressive symptoms were measured by the Center for Epidemiologic Studies Depression Scale with a cut-off point of 16. Self-reported SHS exposure was defined as non-smokers׳ inhalation of the smoke exhaled from smokers on at least one day a week. The multivariable logistic regression analysis was completed with adjustment for potential confounders. Among 1280 middle-aged women, 19.4% were classified as having depressive symptoms. There was a 104% increased odds of depressive symptoms corresponding to SHS exposure in general (OR=2.04, 95% CI 1.48-2.79) using no exposure as reference. There were significant positive relations between SHS exposure in general and depressive symptoms in a dose-response manner. These significant trends were observed consistently whether SHS exposure occurred in homes or workplaces. Our findings suggest that long-term and regular SHS exposure is associated with a significant, dose-dependent increase in risk of depressive symptoms. PMID:26231582

    We aimed to compare the micronutrient usage and other lifestyle behaviors over 10 years among those with and without age-related macular degeneration (AMD). 1612 participants aged 49+ years at baseline were re-examined over 10 years, west of Sydney, Australia. AMD was assessed from retinal photographs. Dietary data were collected using a semi-quantitative food frequency questionnaire. Smoking status was self-reported. 56 participants had any AMD at baseline, of these 25% quit smoking at 5 years and were still not smoking at 10-year follow-up. Among participants who had below the recommended intake of vitamins A, C or E supplements at baseline, those who did compared to those who did not develop late AMD over 10 years were more likely to report vitamins A (total), C or E supplement intake above the recommended intake at 10-year follow-up: multivariable-adjusted OR 4.21 (95% CI 1.65-10.73); OR 6.52 (95% CI 2.76-15.41); and OR 5.71 (95% CI 2.42-13.51), respectively. Participants with compared to without AMD did not appreciably increase fish, fruit and vegetable consumption and overall diet quality. Adherence to smoking and dietary recommendations was poor among older adults with AMD. However, uptake of antioxidant supplements increased significantly among those with late AMD. PMID:25822372

    Objective/background Factors such as body size (weight and body mass index [BMI]), age, sex, and race might influence the clinical response to sumatriptan. We evaluated the impact of these covariates on the plasma concentration (Cp) profile of sumatriptan administered subcutaneously. Methods We conducted three pharmacokinetic studies of subcutaneous sumatriptan in 98 healthy adults. Sumatriptan was administered subcutaneously (236 administrations) as either DFN-11 3 mg, a novel 0.5 mL autoinjector being developed by Dr. Reddy’s Laboratories; Imitrex® (Sumatriptan) injection 3 mg or 6 mg (6 mg/0.5 mL); or Imitrex STATdose 4 mg or 6 mg (0.5 mL). Blood was sampled for 12 hours to determine sumatriptan Cp. Maximum Cp (Cmax), area under the curve during the first 2 hours (AUC0–2), and total area under the curve (AUC0–∞) were determined using noncompartmental methods. Post hoc analyses were conducted to determine the relationship between these exposure metrics and each of body weight, BMI, age, sex, and race (categorized as white, black, or others). Results Both weight and BMI correlated negatively with each exposure metric for each treatment group. Across all treatment groups, AUC0–2 for subjects with BMI less than or equal to median value was 1.03–1.12 times the value for subjects with BMI more than median value. For subjects with BMI less than or equal to median value receiving DFN-11, median AUC0–2 was slightly less than that for subjects with BMI more than median value receiving Imitrex 4 mg and larger than that for subjects with BMI more than median value receiving Imitrex 3 mg. Results were similar for the other exposure metrics and for weight. Exposure was higher in women than in men, which can be attributed in part to differences in weight. There was no relationship between exposure and age. For DFN-11, AUC0–2 and AUC0–∞ were lower in nonwhites compared with whites; the ratio of median values was 0.84 and 0.89, respectively. A similar

    The broad spectrum of economic and cultural diversity in the U.S. population correlates with and affects the study of behavioral aspects of health. The purpose of this article is to provide a selective overview of research findings from the Chicago Health and Aging Project (CHAP), which covers a socio-demographically diverse population in Chicago, with a focus on role-related psychosocial factors and observed racial/ethnic differences in aging outcomes. CHAP is a longitudinal, epidemiological study of common chronic conditions of aging with an emphasis on medical, psychosocial, and environmental risk factors for the decline in cognitive function across the older adult lifespan. We briefly summarize the study design and methods used in the CHAP study and characterize the study population and describe the psychosocial data, noting black-white associations as they relate to three common brain health outcomes: cognitive function and Alzheimer's Disease, stroke, and subclinical vascular disease as noted on neuroimaging.

    There are concerns over nonmedical use of prescription stimulants among youths, but little is known about the extent of use among young Asian-Americans, Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race individuals—the fastest growing segments of the U.S. population. We examined prevalences and correlates of nonmedical stimulant use (NMSU) and disorder (StiUD) for these underrecognized groups. Whites were included as a comparison. Data were from young individuals aged 12–34 years in the 2005–2012 National Surveys on Drug Use and Health. We used logistic regression to estimate odds of past-year NMSU status. Significant yearly increases in lifetime NMSU prevalence were noted in Whites only. NHs/PIs (lifetime 7.33%, past-year 2.72%) and mixed-race individuals (10.20%, 2.82%) did not differ from Whites in NMSU prevalence (11.68%, 3.15%). Asian-Americans (lifetime 3.83%, past-year 0.90%) had lower prevalences than Whites. In each racial/ethnic group, “Methamphetamine/Desoxyn/Methedrine or Ritalin” was more commonly used than other stimulant groups; “got them from a friend/relative for free” and “bought them from a friends/relative” were among the most common sources. Females had greater odds than males of NMSU (among White, NH/PI, mixed-race individuals) and StiUD (among mixed-race individuals). Young adults (aged 18–25) had elevated odds of NMSU (White, NH/PI); adolescents had elevated odds of StiUD (White, mixed-race). Other substance use (especially marijuana, other prescription drugs) increased odds of NMSU and StiUD. NHs/PIs and mixed-race individuals were as likely as Whites to misuse stimulants. Research is needed to delineate health consequences of NMSU and inform prevention efforts for these understudied, rapidly-growing populations. PMID:25263275

    Few studies have examined disparities in adverse birth outcomes and compared contributing socioeconomic factors specifically between African-American and White teen mothers. This study examined intersections between neighborhood socioeconomic status (as defined by census-tract median household income), maternal age, and racial disparities in preterm birth (PTB) outcomes between African-American and White teen mothers in North Carolina. Using a linked dataset with state birth record data and socioeconomic information from the 2010 US Census, disparities in preterm birth outcomes for 16,472 teen mothers were examined through bivariate and multilevel analyses. African-American teens had significantly greater odds of PTB outcomes than White teens (OR = 1.38, 95% CI 1.21, 1.56). Racial disparities in PTB rates significantly varied by neighborhood income; PTB rates were 2.1 times higher for African-American teens in higher income neighborhoods compared to White teens in similar neighborhoods. Disparities in PTB did not vary significantly between teens younger than age 17 and teens ages 17-19, although the magnitude of racial disparities was larger between younger African-American and White teens. These results justify further investigations using intersectional frameworks to test the effects of racial status, neighborhood socioeconomic factors, and maternal age on birth outcome disparities among infants born to teen mothers.

    Background Rhesus-positive and rhesus-negative persons differ in the presence-absence of highly immunogenic RhD protein on the erythrocyte membrane. This protein is a component of NH3 or CO2 pump whose physiological role is unknown. Several recent studies have shown that RhD positivity protects against effects of latent toxoplasmosis on motor performance and personality. It is not known, however, whether the RhD phenotype modifies exclusively the response of the body to toxoplasmosis or whether it also influences effects of other factors. Methodology/Principal Findings In the present cohort study, we searched for the effects of age and smoking on performance, intelligence, personality and self-estimated health and wellness in about 3800 draftees. We found that the positive effect of age on performance and intelligence was stronger in RhD-positive soldiers, while the negative effect of smoking on performance and intelligence was of similar size regardless of the RhD phenotype. The effect of age on four Cattell's personality factors, i.e., dominance (E), radicalism (Q1), self-sentiment integration (Q3), and ergic tension (Q4), and on Cloninger's factor reward dependency (RD) was stronger for RhD-negative than RhD-positive subjects, while the effect of smoking on the number of viral and bacterial diseases was about three times stronger for RhD-negative than RhD-positive subjects. Conclusions RhD phenotype modulates the influence not only of latent toxoplasmosis, but also of at least two other potentially detrimental factors, age and smoking, on human behavior and physiology. The negative effect of smoking on health (estimated on the basis of the self-rated number of common viral and bacterial diseases in the past year) was much stronger in RhD-negative than RhD-positive subjects. It is critically needed to confirm the differences in health response to smoking between RhD-positive and RhD-negative subjects by objective medical examination in future studies. PMID

    The authors assessed sex and age differences in secondhand smoke (SHS) exposure among vulnerable adolescent populations. Data from the 2013 Korea Youth Risk Behavior Web-based Survey of 64,499 non-smokers aged 13–18 years were analyzed using multiple logistic regression. Girls were exposed 1.26 times (95% confidence interval, 1.21–1.32) more to home SHS than boys, and the younger adolescents were more likely to be exposed to home SHS than were the older, regardless of sex (p < 0.001). Younger girls living with or without current smokers and the younger boys living with current smokers were more likely to be exposed to SHS at home, when the data were stratified according to current household member smoking, which was one of the main risk factors for SHS exposure at home. Girls living with current smokers were more likely to be exposed to SHS at home than boys regardless age. Girls and younger adolescents, populations vulnerable to smoke exposure, were more likely to be exposed to SHS at home, even though they should be more protected. It is necessary to improve home SHS awareness, especially among these vulnerable populations. PMID:26907314

    This study tested the hypothesis that cigarette smoking adoption among adolescents could be suppressed by providing school-based videotape instruction for resisting social influences to smoke. The utilization of same-age peer leaders was also varied to test whether their participation in the classroom would enhance program effects. Seventh grade students (N = 540) from one junior high school in Southern California were randomly assigned by classrooms (N = 15) to: (a) videotape instruction, (b) videotape instruction plus peer leader involvement, or (c) survey-only. Seventh grade students (N = 234) in a second junior high school served as a measurement-only control. Assessments were conducted at the beginning and end of the academic year. Results revealed a marked suppression in the onset of both experimental and regular smoking among those students exposed to the pressure resistance training with peer leader involvement. Pressure resistance training without peer leader involvement produced a more variable and less powerful effect on students' smoking behavior. Data collected on students' use of alcohol and marijuana revealed a generalized suppression effect, albeit weaker than for tobacco, among those students exposed to the social resistance training with peer leader involvement. Results provide further encouraging support for the use of peer-led pressure resistance training in preventing adolescent drug use. PMID:2316409

    Little is known about the racial patterns of crimes committed by sexual homicide offenders (SHOs). This study examined race and age influences on victim-offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976-2005) was used. Analyses of victim-offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race- and age-based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, "intra-racially" (range 91-100%) across four victim age categories, whereas Black SHOs killed both intra-racially (range 24-82%) and inter-racially (18-76%), with the likelihood of their killing inter-racially increasing as the age of the victim increased. This study underscores the importance of considering victim-offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling. PMID:20487160

    Objective Small increases in smoking restrictions in cars and homes were reported after legislation prohibiting smoking in public places. Few studies examine whether these changes continued in the longer term. This study examines changes in restrictions on smoking in cars and homes, and child exposure to secondhand smoke (SHS) in these locations, since 2008 postlegislation surveys in Wales. Setting State-maintained primary schools in Wales (n=75). Participants Children aged 10–11 years (year 6) completed CHETS (CHild exposure to Environmental Tobacco Smoke) Wales surveys in 2007 (n=1612) and 2008 (n=1605). A replication survey (CHETS Wales 2) was conducted in 2014, including 1601 children. Primary outcome variable Children's reports of whether smoking was allowed in their car or home and exposure to SHS in a car or home the previous day. Results The percentage of children who reported that smoking was allowed in their family vehicle fell from 18% to 9% in 2014 (OR=0.42; 95% CI 0.33 to 0.54). The percentage living in homes where smoking was allowed decreased from 37% to 26% (OR=0.30; 95% CI 0.20 to 0.43). Among children with a parent who smoked, one in five and one in two continued to report that smoking was allowed in their car and home. The percentage reporting SHS exposure in a car (OR=0.52; 95% CI 0.38 to 0.72) or home (OR=0.44; 95% CI 0.36 to 0.53) the previous day also fell. Children from poorer families remained less likely to report smoking restrictions. Conclusions Smoking in cars and homes has continued to decline. Substantial numbers of children continue to report that smoking is allowed in cars and homes, particularly children from poorer families. A growing number of countries have legislated, or plan to legislate, banning smoking in cars carrying children. Attention is needed to the impact of legislation on child health and health inequalities, and reducing smoking in homes. PMID:25636793

    Smokers of all ages can benefit by quitting, but many smokers continue to smoke. Older Greek-Australian smokers, one of the largest ethnic groups in Australia, have higher rates of smoking than other groups of older Australians. This qualitative study aimed to explore older Greek-Australians' views about socio-cultural influences on their smoking. A snowball sampling technique was used to identify twenty Greek-Australian smokers (12 males and eight females), aged ≥50 years. They were recruited through the Greek Orthodox Community Center of South Australia (GOCSA). Qualitative data were collected using semi-structured face-to-face interviews. The audio-taped interviews were translated and transcribed, and then analysed using content analysis. Results suggested that smoking was considered as the "norm" by older Greek-Australian smokers. There were four groups embedded in the participants' social networks that were reported to be important in relation to either encouraging smoking or, smoking abstinence. These support groups included: family members, friends, the Greek community, and physicians. Smokers' family members (brothers) and friends were identified as facilitators of smoking whereas non-smoker family members (children and spouses) were reported as providing barriers to smoking. Different approaches were used by supporter groups to assist smokers to quit smoking-both planned and unplanned. Knowledge, planning of social and cultural supports, and addressing barriers to smoking cessation are a important part of health planning for older Greek-Australians. Social norms, including those arising from social interactions, and predisposing traits can influence smoking behaviour. Addressing the specific barriers to smoking cessation of older Greek-Australians is critical to addressing the risk for chronic disease in this group. PMID:25739006

    We document racial/ethnic and nativity differences in U.S. smoking patterns among adolescents and young adults using the 2006 Tobacco Use Supplement to the Current Population Survey (n=44,202). Stratifying the sample by nativity status within five racial/ethnic groups (Asian American, Mexican American, other Hispanic, non-Hispanic black, and non-Hispanic white), and further by sex and age, we compare self-reports of lifetime smoking across groups. U.S.-born non-Hispanic whites, particularly men, report smoking more than individuals in other racial/ethnic/nativity groups. Some groups of young women (e.g., foreign-born and U.S.-born Asian Americans, foreign-born and U.S.-born Mexican Americans, and foreign-born blacks) report extremely low levels of smoking. Foreign-born females in all of the 25-34 year old racial/ethnic groups exhibit greater proportions of never smoking than their U.S.-born counterparts. Heavy/moderate and light/intermittent smoking is generally higher in the older age group among U.S.-born males and females whereas smoking among the foreign-born of both sexes is low at younger ages and remains low at older ages. Taken together, these findings highlight the importance of considering both race/ethnicity and nativity in assessments of smoking patterns and in strategies to reduce overall U.S. smoking prevalence and smoking-attributable health disparities.

    Worldwide, stroke is the second leading cause of death and leading cause of disability. Women experience over half of all strokes, 60% of stroke-related deaths, and a death rate of 11% versus 8.4% for men. To understand the delay in stroke recognition and treatment, a convenience sample of 97 midlife women living in southeast North Carolina completed the Stroke Recognition Questionnaire. Rural women, younger women (<49 years old), and participants with incomes under $35,601 had higher stroke symptom and risk factor knowledge scores. Educational interventions should target women over the age of 50, and should distinguish between symptoms of stroke versus heart attack. PMID:22946594

    Systemic inflammation promotes cardiovascular disease. Inflammatory connective tissue diseases (CTD) like lupus and rheumatoid arthritis associate with cardiovascular risk, but it is unknown whether particular groups of patients have enhanced propensity for atherosclerotic cardiovascular disease (ASCVD) associated with their CTD. Analysis of aggregate health record data at a large U.S. academic center identified CTD and ASCVD status for 287,467 African American and white adults. ASCVD prevalence in those with CTD was 29.7% for African Americans and 14.7% for white patients with prevalence ratios, compared to those without CTD, of 3.1 and 1.8, respectively. When different types of CTD were analyzed individually (rheumatoid arthritis; lupus; scleroderma; Sjögren Syndrome; dermatomyositis/polymyositis; unspecified/mixed CTD; other inflammatory arthropathy), increased ASCVD rates were found in nearly all subsets, always with higher prevalence ratios in African Americans. The prevalence ratio of ASCVD was particularly high in young African Americans. Furthermore, individuals lacking traditional cardiovascular risk factors had more ASCVD if they had CTD (prevalence ratio 2.9). Multivariate analysis confirmed a positive interaction between CTD and African-American race and a negative interaction between CTD and age. The factors driving the observed disproportionate CTD-associated ASCVD in African Americans, young adults, and those without traditional risk factors warrant further study. PMID:26842423

    Using genome-wide genotypes, we characterized the genetic structure of 103,006 participants in the Kaiser Permanente Northern California multi-ethnic Genetic Epidemiology Research on Adult Health and Aging Cohort and analyzed the relationship to self-reported race/ethnicity. Participants endorsed any of 23 race/ethnicity/nationality categories, which were collapsed into seven major race/ethnicity groups. By self-report the cohort is 80.8% white and 19.2% minority; 93.8% endorsed a single race/ethnicity group, while 6.2% endorsed two or more. Principal component (PC) and admixture analyses were generally consistent with prior studies. Approximately 17% of subjects had genetic ancestry from more than one continent, and 12% were genetically admixed, considering only nonadjacent geographical origins. Self-reported whites were spread on a continuum along the first two PCs, indicating extensive mixing among European nationalities. Self-identified East Asian nationalities correlated with genetic clustering, consistent with extensive endogamy. Individuals of mixed East Asian-European genetic ancestry were easily identified; we also observed a modest amount of European genetic ancestry in individuals self-identified as Filipinos. Self-reported African Americans and Latinos showed extensive European and African genetic ancestry, and Native American genetic ancestry for the latter. Among 3741 genetically identified parent-child pairs, 93% were concordant for self-reported race/ethnicity; among 2018 genetically identified full-sib pairs, 96% were concordant; the lower rate for parent-child pairs was largely due to intermarriage. The parent-child pairs revealed a trend toward increasing exogamy over time; the presence in the cohort of individuals endorsing multiple race/ethnicity categories creates interesting challenges and future opportunities for genetic epidemiologic studies.

    Laboratory social stress tests involving public speaking challenges are widely used for eliciting an acute stress response in older children, adolescents, and adults. Recently, a group protocol for a social stress test (the Trier Social Stress Test for Groups, TSST-G) was shown to be effective in adults and is dramatically less time-consuming and resource-intensive compared to the single-subject version of the task. The present study sought to test the feasibility and effectiveness of an adapted group public speaking task conducted with a racially diverse, urban sample of U.S. adolescents (N=191; 52.4% female) between the ages of 11 and 18 (M=14.4 years, SD=1.93). Analyses revealed that this Group Public Speaking Task for Adolescents (GPST-A) provoked a significant increase in cortisol production (on average, approximately 60% above baseline) and in self-reported negative affect, while at the same time avoiding excessive stress responses that would raise ethical concerns or provoke substantial participant attrition. Approximately 63.4% of participants exhibited an increase in cortisol levels in response to the task, with 59.2% of the total sample showing a 10% or greater increase from baseline. Results also suggested that groups of five adolescents might be ideal for achieving more uniform cortisol responses across various serial positions for speech delivery. Basal cortisol levels increased with age and participants belonging to U.S. national minorities tended to have either lower basal cortisol or diminished cortisol reactivity compared to non-Hispanic Whites. This protocol facilitates the recruitment of larger sample sizes compared to prior research and may show great utility in answering new questions about adolescent stress reactivity and development.

    Using the National Health and Nutrition Examination Surveys (NHANES) 1999-2004, the authors examined age patterns in oral health indicators by race/ethnicity and socioeconomic status related to edentulism, presence of root caries, and periodontal disease. Our analysis included subjects who were non-Hispanic White, Mexican American, and African American over the age of 20, and who participated in the NHANES oral health examination. African Americans experienced more oral health problems at younger ages; as age increased, so did racial disparities in oral health problems. Lower educational attainment was strongly associated with more oral health problems at all ages. These results may indicate a faster progression of oral health problems with age among African Americans, thus suggesting that the "earlier aging" of members of racial/ethnic minorities which has been reported in prior research may also be found in oral health.

    This study examined if temporal variations in daily cigarette smoking and never smoking among groups with different levels of education fit the pattern proposed by the theory of diffusion of innovations (TDI), while taking into account the separate effects of age, period and birth cohort (APC). Aggregated data from nationally representative interview surveys from Norway from 1976 to 2010 was used to calculate probabilities of smoking using an APC approach in which the period variable was normalized to pick up short term cyclical effects. Results showed that educational differences in smoking over time were more strongly determined by birth cohort membership than variations in smoking behavior across the life course. The probability of daily smoking decreased faster across cohorts among higher compared to lower educated. In contrast, the change in probability of never having smoked across cohorts was similar in the two education groups, but stronger among men compared to women. Moreover, educational differences in both daily and never smoking increased among early cohorts and leveled off among late cohorts. The results emphasizes the importance of birth cohort for social change and are consistent with TDI, which posits that smoking behavior diffuse through the social structure over time. PMID:25131273

    Smokers of all ages can benefit by quitting, but many smokers continue to smoke. Older Greek-Australian smokers, one of the largest ethnic groups in Australia, have higher rates of smoking than other groups of older Australians. This qualitative study aimed to explore older Greek-Australians’ views about socio-cultural influences on their smoking. A snowball sampling technique was used to identify twenty Greek–Australian smokers (12 males and eight females), aged ≥ 50 years. They were recruited through the Greek Orthodox Community Center of South Australia (GOCSA). Qualitative data were collected using semi-structured face-to-face interviews. The audio-taped interviews were translated and transcribed, and then analysed using content analysis. Results suggested that smoking was considered as the “norm” by older Greek-Australian smokers. There were four groups embedded in the participants’ social networks that were reported to be important in relation to either encouraging smoking or, smoking abstinence. These support groups included: family members, friends, the Greek community, and physicians. Smokers’ family members (brothers) and friends were identified as facilitators of smoking whereas non-smoker family members (children and spouses) were reported as providing barriers to smoking. Different approaches were used by supporter groups to assist smokers to quit smoking—both planned and unplanned. Knowledge, planning of social and cultural supports, and addressing barriers to smoking cessation are a important part of health planning for older Greek-Australians. Social norms, including those arising from social interactions, and predisposing traits can influence smoking behaviour. Addressing the specific barriers to smoking cessation of older Greek-Australians is critical to addressing the risk for chronic disease in this group. PMID:25739006

    Cadmium is a toxic, bioaccumulated heavy metal with a half-life of one to four decades in humans (CDC, 2005). Primary exposure sources include food and tobacco smoke. In our population-based study, a risk-factor interview was conducted as part of a breast cancer study for 251 randomly selected women living in Wisconsin (USA), aged 20-69 yr, and spot-urine specimens were also obtained. Urine collection kits were carefully designed to minimize trace element contamination during specimen collection and handling in each participant's home. Urine cadmium concentrations were quantified using inductively coupled plasma-mass spectrometry, and creatinine levels and specific gravity were also determined. Statistically significant increasing creatinine-adjusted urinary cadmium mean levels relative to smoking status (never, former, and current respectively) were observed. A difference in mean cadmium levels for nonsmokers who reported environmental tobacco smoke exposure during childhood or the recent past (approximately 2 yr prior to the interview) for exposure at home, at work, or in social settings compared to those who reported no exposure was not found.

    Our primary objective was to estimate, by one year and five year intervals, maternal age specific risk rates for Down syndrome among whites and among other races from two different populations, metropolitan Atlanta and south west Ohio, using live birth and prenatally diagnosed cases ascertained during 1970-1989. The five year estimates were also calculated separately for each of the five four year periods during these 20 years. Additionally, we compared two different methods of estimating these risk rates by using a third population of whites, and compared two different statistical methods of smoothing the risk rates. The results indicate good agreement between the metropolitan Atlanta and south west Ohio estimates within races, but show a statistically significant difference between the two race categories. Because 86% of live births in the "other races" category in the combined population are to blacks, these data may be seen as the first estimates of maternal age specific risk rates for Down syndrome among blacks calculated by one year intervals. We found excellent agreement in the risk rate estimates among the five four year time periods, between the estimates obtained by using the two different methods of estimation, and between the estimates obtained using the two different methods of statistical smoothing. Our estimated risk rates for white women in their 20s strongly reinforce those from previous studies currently being used for genetic counselling purposes. While we did find somewhat higher rates for women under 20, and increasingly higher rates for those over 30 years of age, these differences are not substantial. Thus, this study in general supports the risk rates estimated from data collected mostly during the 1960s and 1970s. PMID:9643290

    We present methods for estimating five-year birth-cohort-specific trends in smoking behavior for individuals born between 1910 and 1984. We combine cross-sectional survey data on smoking behavior from the National Health Interview Surveys (NHIS) conducted between 1965 and 2001 into a single data set. The cumulative incidence of smoking by year of age and calendar year is constructed for each birth cohort from this data set and the effect of differential mortality on ever smoking prevalence is adjusted by modeling the ever smoking prevalence of each cohort for each survey year and back extrapolating that effect to age 30. Cumulative incidence is then scaled to match the ever smoking prevalence at age 30. Survival analyses generate the cumulative cessation among ever smokers across year of age and calendar year and are used to estimate current smoking prevalence. Data from Substance Abuse and Mental Health Services Administration (SAMHSA) National Survey on Drug Use and Health is used to divide those initiating smoking into quintiles of number of cigarettes smoked per day (CPD) and the mean CPD for each quintile in each calendar year is estimated from the NHIS data. For five-year birth cohorts of white, african-american, Hispanic and all race/ethnicity groupings of males and females born between 1910 and 1984, estimates are provided for prevalence of current and ever smoking, incidence of cessation, incidence of initiation, and the distribution of smoking duration and CPD for each calendar year and each single year of age through the year 1999. We believe that we are the first to provide birth-cohort-specific estimates of smoking behaviors for the U.S. population that include distributions of duration of smoking and number of cigarettes per day. These additional elements substantively enhance the utility of these estimates for estimating lung cancer risks. PMID:22882884

    Globally, tobacco use is associated with 5 million deaths per annum and is regarded as one of the leading causes of premature death. Major chronic disorders associated with smoking include cardiovascular diseases, several types of cancer, and chronic obstructive pulmonary disease (lung problems). Cigarette smoking (CS) generates a cumulative oxidative stress, which may contribute to the pathogenesis of chronic diseases. Mainstream and side stream gas-phase smoke each have about the same concentration of reactive free radical species, about 1 × 10(16) radicals per cigarette (or 5 × 10(14) per puff). This effect is critical in understanding the biologic effects of smoke. Several lines of evidence suggest that cigarette smoke constituents can directly activate vascular reactive oxygen species production. In this work we present multiple evidence that CS provide the important risk factors in many age-related diseases, and is associated with increased cumulative and systemic oxidative stress and inflammation. The cited processes are marked by increased white blood cell (leucocytes, WBCs) turnover. The data suggest an alteration of the circulating WBCs by CS, resulting in increased adherence to endothelial cells. Telomeres are complex DNA-protein structures located at the end of eukaryotic chromosomes. Telomere length shortens with biologic age in all replicating somatic cells. It has been shown that tobacco smoking enhances telomere shortening in circulating human WBCs. Telomere attrition (expressed in WBCs) can serve as a biomarker of the cumulative oxidative stress and inflammation induced by smoking and, consequently, show the pace of biologic aging. We originally propose that patented specific oral formulations of nonhydrolized carnosine and carcinine provide a powerful tool for targeted therapeutic inhibition of cumulative oxidative stress and inflammation and protection of telomere attrition associated with smoking.

    Background and objective Personal smoking is widely regarded to be the primary cause of chronic bronchitis (CB) in adults, but with limited knowledge of contributions by other factors, including current asthma. We aimed to estimate the independent and relative contributions to adult CB from other potential influences spanning childhood to middle age. Methods The population-based Tasmanian Longitudinal Health Study cohort, people born in 1961, completed respiratory questionnaires and spirometry in 1968 (n=8,583). Thirty-seven years later, in 2004, two-thirds responded to a detailed postal survey (n=5,729), from which the presence of CB was established in middle age. A subsample (n=1,389) underwent postbronchodilator spirometry between 2006 and 2008 for the assessment of chronic airflow limitation, from which nonobstructive and obstructive CB were defined. Multivariable and multinomial logistic regression models were used to estimate relevant associations. Results The prevalence of CB in middle age was 6.1% (95% confidence interval [CI]: 5.5, 6.8). Current asthma and/or wheezy breathing in middle age was independently associated with adult CB (odds ratio [OR]: 6.2 [95% CI: 4.6, 8.4]), and this estimate was significantly higher than for current smokers of at least 20 pack-years (OR: 3.0 [95% CI: 2.1, 4.3]). Current asthma and smoking in middle age were similarly associated with obstructive CB, in contrast to the association between allergy and nonobstructive CB. Childhood predictors included allergic history (OR: 1.3 [95% CI: 1.1, 1.7]), current asthma (OR: 1.8 [95% CI: 1.3, 2.7]), “episodic” childhood asthma (OR: 2.3 [95% CI: 1.4, 3.9]), and parental bronchitis symptoms (OR: 2.5 [95% CI: 1.6, 4.1]). Conclusion The strong independent association between current asthma and CB in middle age suggests that this condition may be even more influential than personal smoking in a general population. The independent associations of childhood allergy and asthma, though not

    2015-01-01

    This review explores the limitations of self-reported race, ethnicity, and genetic ancestry in biomedical research. Various terminologies are used to classify human differences in genomic research including race, ethnicity, and ancestry. Although race and ethnicity are related, race refers to a person's physical appearance, such as skin color and eye color. Ethnicity, on the other hand, refers to communality in cultural heritage, language, social practice, traditions, and geopolitical factors. Genetic ancestry inferred using ancestry informative markers (AIMs) is based on genetic/genomic data. Phenotype-based race/ethnicity information and data computed using AIMs often disagree. For example, self-reporting African Americans can have drastically different levels of African or European ancestry. Genetic analysis of individual ancestry shows that some self-identified African Americans have up to 99% of European ancestry, whereas some self-identified European Americans have substantial admixture from African ancestry. Similarly, African ancestry in the Latino population varies between 3% in Mexican Americans to 16% in Puerto Ricans. The implication of this is that, in African American or Latino populations, self-reported ancestry may not be as accurate as direct assessment of individual genomic information in predicting treatment outcomes. To better understand human genetic variation in the context of health disparities, we suggest using "ancestry" (or biogeographical ancestry) to describe actual genetic variation, "race" to describe health disparity in societies characterized by racial categories, and "ethnicity" to describe traditions, lifestyle, diet, and values. We also suggest using ancestry informative markers for precise characterization of individuals' biological ancestry. Understanding the sources of human genetic variation and the causes of health disparities could lead to interventions that would improve the health of all individuals. PMID:25563503

    Secondhand cigarette smoke exposure (SSE) has been linked to carcinogenic, oxidative, and inflammatory reactions. Herein, we investigated whether premature skin aging could be induced by SSE in a rat model, and assessed the cytoplasmic translocation of high mobility group box 1 (HMGB1) protein and collagen loss in skin tissues. Animals were divided into two groups: SSE and controls. Whole body SSE was carried out for 12 weeks. Dorsal skin tissue specimens were harvested for HMGB1 and Mallory's azan staining. Correlations between serum HMGB1 and collagen levels were determined. Rat skin exposed to secondhand smoke lost collagen bundles in the papillary dermis and collagen decreased significantly (p<0.05) compared with control rats. In epidermal keratinocytes, cytoplasmic HMGB1 staining was more diffuse and there were more HMGB1-positive cells after four weeks in SSE compared to control rats. A negative correlation between HMGB1 serum and collagen levels (r=-0.631, p=0.28) was also observed. Therefore, cytoplasmic HMGB1 expression in skin tissues might be associated with skin collagen loss upon the initiation of SSE. Additionally, long-term SSE might affect the appearance of the skin, or could accelerate the skin aging process. PMID:25446104

    Subjective health status was assessed in relation to overweight by administering a list of 51 health complaints to adult men and women who were either chronically overweight as defined by Body Mass Index (BMI) or not overweight, in a continuous morbidity registration in four general practices during the period 1967-83. Responses were received from 455 men (182 overweight) and 790 women (386 overweight), ages 26-66 years. Response rate (71 per cent) and age distribution (mean age 48) were similar in overweight and non-overweight groups of both sexes. BMI was correlated with the total number of complaints in women (r = 0.15) but not in men (r = 0.07). Multiple regression analysis revealed, however, that age was an effect modifier in this relation, there being a negative association between BMI and subjective health in younger men and a positive association in older men, whereas in women the association between BMI and subjective health was much more pronounced at younger ages than at older ages. In addition, current smoking habits and social class (in men and women) and reported slimming behavior (in women) had an independent relation to the total number of health complaints. BMI was also related to specific complaints and groups of complaints, particularly in women. PMID:3777287

    Objectives. Associations between subjective social status, a subjective measure of socioeconomic status, and predictors of risk for postpartum smoking were examined among 123 pregnant women (aged 18–24 years) who stopped smoking because of pregnancy. The goal was to identify how subjective social status might influence the risk for postpartum smoking and to elucidate targets for intervention. Methods. We used multiple regression equations to examine the predictive relations between subjective social status and tobacco dependence, self-rated likelihood of postpartum smoking, confidence, temptations, positive and negative affect, depression, stress, and social support. Adjusted analyses were also conducted with control for race/ethnicity, education, income, and whether participant had a partner or not (partner status). Results. In unadjusted and adjusted analyses, subjective social status predicted tobacco dependence, likelihood of postpartum smoking, confidence, temptations, positive affect, negative affect, and social support. Adjusted analyses predicting depression and stress approached significance. Conclusions. Among young pregnant women who quit smoking because of pregnancy, low subjective social status was associated with a constellation of characteristics indicative of increased vulnerability to postpartum smoking. Subjective social status provided unique information on risk for postpartum smoking over and above the effects of race/ethnicity, objective socioeconomic status, and partner status. PMID:17600249

    This study assessed the effect of race/ethnicity on the prevalence of inconsistent reports regarding ever smoking, time since smoking cessation, and age of initiating regular smoking. We used the Tobacco Use Supplement to the Current Population Survey data, which came from a test-retest reliability study, and considered three racial/ethnic subpopulations, Hispanics, Non-Hispanic (NH) Blacks and NH Whites. Initial exploration of highly disagreeing reports of time since smoking cessation and age of onset of regular smoking initiation indicated that the majority of these reports corresponded to NH Whites. However, the proportion of the extremely discrepant reports was very small (less than 0.8%), and these reports were not included in the main analyses. Univariate analyses revealed that for each smoking measure, NH Whites tended to report most consistently when compared to Hispanics and NH Blacks. However, the only statistically significant result was that Hispanics were more likely to report their regular smoking initiation age inconsistently than were NH Whites. Analyses that adjusted for other factors confirmed this finding, i.e., Hispanics were 1.8 times more likely to provide inconsistent reports of their age of onset of regular smoking than were NH Whites. Furthermore, these analyses showed that the impact of race/ethnicity on the prevalence of inconsistent reporting may depend on other factors, e.g., age and employment status. For example, non-employed NH Blacks were 1.9 times more likely to recant ever smoking than were non-employed NH Whites. The lower consistency in reports by Hispanics and NH Blacks underscores the importance of developing new survey design and research strategies for detecting relatively small differences in reporting among the racial/ethnic minorities. Additional efforts to motivate racial/ethnic minorities to participate in national surveys may not only help increase representation of these subpopulations in study samples but also help

    Introduction The present study expands previous research on early experiences with tobacco by using a Multiple Indicator Multiple Causes (MIMIC) model, which permits combining indicators tapping into pleasant experiences into one latent construct and those indicators of unpleasant experiences into another latent construct. Methods A sample of 458 participants was recruited via newspaper advertisements. Response to early experimentation with cigarettes was assessed using the Early Smoking Experiences questionnaire, in which participants were asked the following question: “The first time you tried cigarettes, did you experience any of the following? (pleasurable and displeasurable sensations [overall], pleasurable rush or buzz, dizziness, relaxation, nausea, cough, difficulty inhaling).” These experiences were rated on a scale ranging from 1 = none to 4 = intense. Results The MIMIC model revealed that current smoking status and age of initial experimentation with cigarettes were significantly associated with both early pleasant and unpleasant experiences (p < .05). African Americans were less likely than Whites to have early unpleasant experiences (p < .05). No association was found between race and early pleasant experiences. Discussion Our findings are consistent with the inferences that pleasant experiences in response to early experimentation with smoking lead to regular smoking and that positive experiences play a stronger role than negative experiences in the transition to regular smoking. Our study also demonstrates that the MIMIC model is pertinent and practicable in nicotine and smoking research. We recommend it as a useful tool for identifying endophenotypes related to nicotine dependence and tobacco use latent constructs. PMID:19578152

    Objective Cigarette smoking is the leading preventable cause of death and disease in the United States. Sexual minorities (lesbians, gay men, and bisexuals), smoke at higher rates than the general population. However, little else is known about sexual minority smokers. Furthermore, the sexual minority population is diverse and little research exists to determine whether subgroups, such as lesbians, gay men, and female and male bisexuals, differ on smoker characteristics. We examine differences in smoking characteristics (advertising receptivity, age of first cigarette, non-daily smoking, cigarettes per day, nicotine dependence, desire to quit and past quit attempts) among lesbians, gay men, and female and male bisexual adults in the United States. Methods Secondary analysis of the CDC's 2009–2010 National Adult Tobacco Survey (N = 118,590). Results Controlling for age, race, socioeconomic status and geographic region, identifying as a female bisexual was associated with fewer past quit attempts, lower age at first cigarette, and higher nicotine dependence when compared to heterosexual women. There were no differences in desire to quit between male or female sexual minorities and their heterosexual counterparts. Conclusion Sexual minority individuals smoke at higher rates than heterosexuals and yet similarly desire to quit. Tailored efforts may be needed to address smoking among bisexual women.

    Background Smoking during pregnancy is common among Inuit women from the Canadian Arctic. Yet, prenatal cigarette smoke exposure (PCSE) is seen as a major risk factor for childhood behavior problems. Recent data also suggest that co-exposure to neurotoxic environmental contaminants can exacerbate the effects of PCSE on behavior. This study examined the association between PCSE and behavior at school age in a sample of Inuit children from Nunavik, Québec, where co-exposure to environmental contaminants is also an important issue. Interactions with lead (Pb) and mercury (Hg), two contaminants associated with behavioral problems, were also explored. Methods Participants were 271 children (mean age = 11.3 years) involved in a prospective birth-cohort study. PCSE was assessed through maternal recall. Assessment of child behavior was obtained from the child’s classroom teacher on the Teacher Report Form (TRF) and the Disruptive Behavior Disorders Rating Scale (DBD). Exposure to contaminants was assessed from umbilical cord and child blood samples. Other confounders were documented by maternal interview. Results After control for contaminants and confounders, PCSE was associated with increased externalizing behaviors and attention problems on the TRF and higher prevalence of attention deficit hyperactivity disorder (ADHD) assessed on the DBD. No interactions were found with contaminants. Interpretation This study extends the existing empirical evidence linking PCSE to behavioral problems in school-aged children by reporting these effects in a population where tobacco use is normative rather than marginal. Co-exposure to Pb and Hg do not appear to exacerbate tobacco effects, suggesting that these substances act independently. PMID:23916943

    Background: Although smoking has a known association with hot flashes, the factors distinguishing smokers at greatest risk for menopausal symptoms have not been well delineated. Recent evidence supports a relationship between menopausal symptoms and variants in several genes encoding enzymes that metabolize substrates such as sex steriods, xenobiotics, and catechols. It is currently not known whether the impact of smoking on hot flashes is modified by the presence of such variants. Objective: The objective of the study was to investigate the relationship between smoking and hot flash occurrence as a function of genetic variation in sex steroid-metabolizing enzymes. Methods: A cross-sectional analysis of data from the Penn Ovarian Aging study, an ongoing population-based cohort of late reproductive-aged women, was performed. Smoking behavior was characterized. Single-nucleotide polymorphisms in five genes were investigated: COMT Val158Met (rs4680), CYP1A2*1F (rs762551), CYP1B1*4 (Asn452Ser, rs1800440), CYP1B1*3 (Leu432Val, rs1056836), and CYP3A4*1B (rs2740574). Results: Compared with nonsmokers, European-American COMT Val158Met double-variant carriers who smoked had increased odds of hot flashes [adjusted odds ratio (AOR) 6.15, 95% confidence interval (CI) 1.32–28.78)]; European-American COMT Val158Met double-variant carriers who smoked heavily had more frequent moderate or severe hot flashes than nonsmokers (AOR 13.7, 95% CI 1.2–154.9). European-American CYP 1B1*3 double-variant carriers who smoked described more frequent moderate or severe hot flashes than nonsmoking (AOR 20.6, 95% CI 1.64–257.93) and never-smoking (AOR 20.59, 95% CI 1.39–304.68) carriers, respectively. African-American single-variant CYP 1A2 carriers who smoked were more likely to report hot flashes than the nonsmoking carriers (AOR 6.16, 95% CI 1.11–33.91). Conclusion: This is the first report demonstrating the effects of smoking within the strata of gene variants involved in sex

    Novice and light adolescent smokers can develop symptoms of nicotine dependence, which predicts smoking behavior several years into the future. However, little is known about how the association between these early - emerging symptoms and later smoker behaviors may change across time from early adolescence into young adulthood. Data were drawn from a 7-year longitudinal study of experimental (<100 cigarettes/lifetime; N = 594) and light (100+ cigarettes/lifetime, but ≤5 cigarettes/day; N = 152) adolescent smokers. Time-varying effect models were used to examine the relationship between baseline nicotine dependence (assessed at age 15 ± 2 years) and future smoking frequency through age 24, after controlling for concurrent smoking heaviness. Baseline smoking status, race, and sex were examined as potential moderators of this relationship. Nicotine dependence symptoms assessed at approximately age 15 significantly predicted smoking frequency through age 24, over and above concurrent smoking heaviness, though it showed declining trends at older ages. Predictive validity was weaker among experimenters at young ages (<16), but stronger at older ages (20-23), relative to light smokers. Additionally, nicotine dependence was a stronger predictor of smoking frequency for white smokers around baseline (ages 14.5-16), relative to nonwhite smokers. Nicotine dependence assessed in mid-adolescence predicts smoking frequency well into early adulthood, over and above concurrent smoking heaviness, especially among novice smokers and nonwhite smokers. Early-emerging nicotine dependence is a promising marker for screening and interventions aimed at preventing smoking progression. PMID:27312479

    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

    A lack of satisfaction with one's body is common among women with obesity, often prompting unhealthy "dieting." Beyond typically slow improvements in weight and body composition, behavioral factors might also affect change in body satisfaction. Age and race/ethnicity (African American vs. White) might moderate such change. Obese women (N = 246; M(age) = 43 years; M BMI = 39 kg/m(2)) initiating a 6-month cognitive-behaviorally based physical activity and nutrition treatment were assessed on possible predictors of body satisfaction change. At baseline, African American and younger women had significantly higher body satisfaction. The treatment was associated with significant within-group improvements in mood, health behaviors (physical activity and fruit/vegetable intake), and body composition (waist circumference). A multiple regression analysis indicated that mood, health behavior, and body composition changes explained a significant 27% of the variance in body satisfaction change. Of these predictors, changes in mood (β = -.36, p < .001) and health behaviors (β = .18, p = .01) made significant, unique contributions to the variance in change in body satisfaction that was accounted for, while only the measure of actual physiological change (body composition) did not. Neither age nor race/ethnicity was a significant moderator when each was entered separately into the multiple regression equation. Practical implications for leveraging manageable changes in behavioral factors for improving body satisfaction were discussed. PMID:24771083

    Mean blood cadmium (B-Cd) concentrations are two- to threefold higher in smokers than in nonsmokers. The basis for this phenomenon is not well understood. We conducted a detailed, multifaceted study of cadmium exposure in smokers. Groups were older smokers (62±4 years, n = 25, 20% male) and nonsmokers (62±3 years, n = 16, 31% male). Each subject's cigarettes were machine smoked, generating individually paired measures of inhaled cadmium (I-Cd) versus B-Cd; I-Cd and B-Cd were each evaluated three times, at monthly intervals. Urine cadmium (U-Cd) was analyzed for comparison. In four smokers, a duplicate-diet study was conducted, along with a kinetic study of plasma cadmium versus B-Cd. Female smokers had a mean B-Cd of 1.21ng Cd/ml, with a nearly 10-fold range (0.29-2.74ng Cd/ml); nonsmokers had a lower mean B-Cd, 0.35ng Cd/ml (p < 0.05), and narrower range (0.20-0.61ng Cd/ml). Means and ranges for males were similar. Estimates of cadmium amounts inhaled daily for our subjects smoking ≥ 20 cigarettes/day were far less than the 15 µg Cd reported to be ingested daily via diet. This I-Cd amount was too low to alone explain the 3.5-fold elevation of B-Cd in our smokers, even assuming greater cadmium absorption via lungs than gastrointestinal tract; cadmium accumulated in smokers' lungs may provide the added cadmium. Finally, B-Cd appeared to be linearly related to I-Cd values in 75% of smokers, whereas 25% had far higher B-Cd, implying a possible heterogeneity among smokers regarding circulating cadmium concentrations and potentially cadmium toxicity.

    Background Young adults have the highest smoking rate of any age group in the U.S., and new strategies to decrease young adult smoking are needed. The objective of the current study was to identify psychographic and demographic factors associated with current smoking and quitting behaviors among young adults. Methods Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18–25 years) from a web-enabled panel. Analyses were conducted in 2007. Results Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR= 4.43 [95% CI=2.18, 8.60]). Conclusions Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking. PMID:19269128

    Exposing children to secondhand tobacco smoke (SHS) is associated with increased risk for asthma, bronchiolitis and SIDS. The role for changes in the developing CNS contributing to these problems has not been fully explored. We used rhesus macaques to test the hypothesis that SHS exposure during development triggers neuroplastic changes in the nucleus tractus solitarius (NTS), where lung sensory information related to changes in airway and lung function is first integrated. Pregnant monkeys were exposed to filtered air (FA) or SHS for 6 h/day, 5 days/week starting at 50-day gestational age. Mother/infant pairs continued the exposures postnatally to age 3 or 13 months, which may be equivalent to approximately 1 or 4 years of human age, respectively. Whole-cell recordings were made of second-order NTS neurons in transverse brainstem slices. To target the consequences of SHS exposure based on neuronal subgroups, we classified NTS neurons into two phenotypes, rapid-onset spiking (RS) and delayed-onset spiking (DS), and then evaluated intrinsic and synaptic excitabilities in FA-exposed animals. RS neurons showed greater cell excitability especially at age of 3 months while DS neurons received greater amplitudes of excitatory postsynaptic currents (EPSCs). Developmental neuroplasticity such as increases in intrinsic and synaptic excitabilities were detected especially in DS neurons. In 3 month olds, SHS exposure effects were limited to excitatory changes in RS neurons, specifically increases in evoked EPSC amplitudes and increased spiking responses accompanied by shortened action potential width. By 13 months, the continued SHS exposure inhibited DS neuronal activity; decreases in evoked EPSC amplitudes and blunted spiking responses accompanied by prolonged action potential width. The influence of SHS exposure on age-related and phenotype specific changes may be associated with age-specific respiratory problems, for which SHS exposure can increase the risk, such as SIDS

    Previous studies have shown associations between dust exposure or lung burden and emphysema in coal miners, although the separate contributions of various predictors have not been clearly demonstrated. The objective was to quantitatively evaluate the relationship between cumulative exposure to respirable coal mine dust, cigarette smoking, and other factors on emphysema severity. The study group included 722 autopsied coal miners and nonminers in the United States. Data on work history, smoking, race, and age at death were obtained from medical records and questionnaire completed by next-of-kin. Emphysema was classified and graded using a standardized schema. Job-specific mean concentrations of respirable coal mine dust were matched with work histories to estimate cumulative exposure. Relationships between various metrics of dust exposure (including cumulative exposure and lung dust burden) and emphysema severity were investigated in weighted least squares regression models. Emphysema severity was significantly elevated in coal miners compared with nonminers among ever- and never-smokers (P < 0.0001). Cumulative exposure to respirable coal mine dust or coal dust retained in the lungs were significant predictors of emphysema severity (P < 0.0001) after accounting for cigarette smoking, age at death, and race. The contributions of coal mine dust exposure and cigarette smoking were similar in predicting emphysema severity averaged over this cohort. Coal dust exposure, cigarette smoking, age, and race are significant and additive predictors of emphysema severity in this study.

    The purpose of this study was to investigate racial and sex differences on the risk factors for smoking initiation and daily smoking among juvenile justice adolescents, a population that is traditionally ignored in school-based epidemiological samples. This study used archival data collected by juvenile justice authorities for a large sample of juvenile justice adolescents (N=4381), examining interaction terms to determine race and sex differences for risk factors. About 70% of juvenile justice adolescents reported ever having smoked cigarettes while almost half reported daily smoking. Overall predictors of ever and daily smoking included older age, being female, White, use of alcohol, cannabis, and cocaine in the past year, affiliation with smoking peers, not living with at least one parent, and a diagnosis of ADHD. While differences were seen between individual predictor models for both race and sex, the interaction terms did not add significantly to the overall model. These important racial and gender differences in this study suggest that tailored prevention messages and interventions may be needed to be most effective with adolescents in the juvenile justice system. While this study provides a basic foundation of risk factors for smoking among juvenile justice adolescents, future research is needed to assess the efficacy of treatment and prevention interventions with this high risk group of adolescent smokers.

    Objectives. We examined the prevalence and associations between behavioral and identity dimensions of sexual orientation among adolescents in the United States, with consideration of differences associated with race/ethnicity, sex, and age. Methods. We used pooled data from 2005 and 2007 Youth Risk Behavior Surveys to estimate prevalence of sexual orientation variables within demographic sub-groups. We used multilevel logistic regression models to test differences in the association between sexual orientation identity and sexual behavior across groups. Results. There was substantial incongruence between behavioral and identity dimensions of sexual orientation, which varied across sex and race/ethnicity. Whereas girls were more likely to identify as bisexual, boys showed a stronger association between same-sex behavior and a bisexual identity. The pattern of association of age with sexual orientation differed between boys and girls. Conclusions. Our results highlight demographic differences between 2 sexual orientation dimensions, and their congruence, among 13- to 18-year-old adolescents. Future research is needed to better understand the implications of such differences, particularly in the realm of health and health disparities. PMID:24328662

    Stop-smoking counselling is a challenging task in primary health care, its efficacy being often underestimated by the physician. Health care physicians are not very inclined to advise their smoking patients to stop smoking and give specific counselling. This is in contradiction with the expectations of more than two thirds of the smoking patients, who expect their physicians to help them. The present article discusses the therapeutical methods for stop-smoking counselling in primary health care. In particular, the article illustrates the importance for this support (including the possibilities for nicotin substitution in the weaning stage). PMID:7839325

    Background Self-neglect is the behavior of an elderly person that threatens his/her own health and safety, and it is associated with increased morbidity and mortality. However, the scope of the self-neglect in the community population remains unclear. We examined the prevalence of self-neglect and its specific behaviors of hoarding, hygiene and other environmental hazards in a community-dwelling elderly population. Methods A population-based cohort study conducted from 2007 to 2010 in a single cycle in a geographically defined community of 4 adjacent neighborhoods in Chicago, Ill., USA. Participant's personal and home environment was rated on hoarding, personal hygiene, house in need of repair, unsanitary conditions, and inadequate utility. Prevalence estimates were presented across gender, race/ethnicity, education and income levels. Results There were 4,627 older adults in the cohort. The prevalence of self-neglect and specific personal and environmental hazards varied significantly by race/ethnicity and by levels of education and income. For race/ethnicity, black older adults (men 13.2%; women 10.9%) had a significantly higher prevalence of self-neglect than white older adults (men 2.4%; women 2.6%). For those with less than high school education, the prevalence of the self-neglect was 14.7% in men and 10.9% in women. For those with an annual income of less than USD 15,000, the prevalence of self-neglect was 21.7% in men and 15.3% in women. Conclusion The prevalence of self-neglect and specific behaviors of hoarding, poor hygiene, and other environmental hazards are higher among black older adults and among those with lower levels of education and income.

    Secondhand smoke (SHS) is a major risk factor for poor health outcomes among women in China, where proportionately few women smoke. This is especially the case as it pertains to women's reproductive health, specifically migrant women who are exposed to SHS more than the population at large. There are several factors which may increase migrant women's risk of SHS exposure. This paper aims to investigate the prevalence and associated factors of SHS exposure among internal Chinese migrant women of reproductive age. The data used were derived from the 2014 Chinese Labor Dynamic Survey, a national representative panel survey. The age-adjusted rate of SHS exposure of women of reproductive age with migration experience was of 43.46% (95% CI: 40.73%-46.40%), higher than those without migration experience (35.28% (95% CI: 33.66%-36.97%)). Multivariate analysis showed that participants with a marital status of "Widowed" had statistically lower exposure rates, while those with a status of "Cohabitation" had statistically higher exposure. Those with an undergraduate degree or above had statistically lower SHS exposure. Those with increasing levels of social support, and those who currently smoke or drink alcohol, had statistically higher SHS exposure. Participants' different work-places had an effect on their SHS exposure, with outdoor workers statistically more exposed. Our findings suggest that urgent tobacco control measures should be taken to reduce smoking prevalence and SHS exposure. Specific attention should be paid to protecting migrant women of reproductive age from SHS. PMID:27043604

    Having a consistent source of medical care may facilitate diagnosis of autism spectrum disorders (ASD). This study examined predictors of age of ASD diagnosis using data from the 2011-2012 National Survey of Children's Health. Using multiple linear regression analysis, age of diagnosis was predicted by race, ASD severity, having a consistent source of care (CSC), and the interaction between these variables after controlling for birth cohort, birth order, poverty level, parental education, and health insurance. While African American children were diagnosed earlier than Caucasians, this effect was moderated by ASD severity and CSC. Having a CSC predicted earlier diagnosis for Caucasian but not African American children. Both physician and parent behaviors may contribute to diagnostic delays in minority children. PMID:26280401

    Background Populations are aging worldwide. In the United States (US), the older adult (aged ≥65) population will increase rapidly in the decades to come. Identifying public health needs in older adults requires that sample-derived estimates of disability prevalence be produced using transparent methodologies. Objectives Produce estimates of disabilities for the US older adult population by race and ethnicity and present measures on the ‘level of precision’ in the estimates. Design Cross-sectional study used American Community Survey (ACS) Public Use Microdata Sample (PUMS) 3-year file collected during 2009-2011 survey period. Setting Community dwelling population aged ≥65 in US. Participants The 1,494,893 actual survey participants (unweighted count) are said to represent 40,496,512 individuals after population weights are applied (weighted count). From the weighted counts, the average age is 75, about 56% are females, and most (80%) are Non-Latino-Whites (NLW). Results Qualitative comparisons provide some evidence that except for hearing, disability prevalence is highest in Non-Latino-Blacks along the following disability items: independent living (25%); ambulatory (34%); self-care (15%); cognitive (11%); and vision (11%). Person inflation ratios, width of 95% confidence interval, and rates of allocations are smaller in NLWs than all the other race-ethnic groups—suggesting disability estimates for NLWs merit the highest level of confidence. Conclusions Improving measures of health in the older adult population requires that efforts continue to highlight how estimates of disability prevalence have the potential to vary in precision and as a function of various known and unknown factors.

    Biomass burning (BB) is a large source of primary and secondary organic aerosols (POA and SOA). This study addresses the physical and chemical evolution of BB organic aerosols. Firstly, the evolution and lifetime of BB POA and SOA signatures observed with the Aerodyne Aerosol Mass Spectrometer are investigated, focusing on measurements at high-latitudes acquired during the 2008 NASA ARCTAS mission, in comparison to data from other field studies and from laboratory aging experiments. The parameter f60, the ratio of the integrated signal at m/z 60 to the total signal in the organic component mass spectrum, is used as a marker to study the rate of oxidation and fate of the BB POA. A background level of f60~0.3% ± 0.06% for SOA-dominated ambient OA is shown to be an appropriate background level for this tracer. Using also f44 as a tracer for SOA and aged POA and a surrogate of organic O:C, a novel graphical method is presented to characterise the aging of BB plumes. Similar trends of decreasing f60 and increasing f44 with aging are observed in most field and lab studies. At least some very aged BB plumes retain a clear f60 signature. A statistically significant difference in f60 between highly-oxygenated OA of BB and non-BB origin is observed using this tracer, consistent with a substantial contribution of BBOA to the springtime Arctic aerosol burden in 2008. Secondly, a summary is presented of results on the net enhancement of OA with aging of BB plumes, which shows large variability. The estimates of net OA gain range from ΔOA/ΔCO(mass) = -0.01 to ~0.05, with a mean ΔOA/POA ~19%. With these ratios and global inventories of BB CO and POA a global net OA source due to aging of BB plumes of ~8 ± 7 Tg OA yr-1 is estimated, of the order of 5 % of recent total OA source estimates. Further field data following BB plume advection should be a focus of future research in order to better constrain this potentially important contribution to the OA burden.

    The aims of the present study was to investigate the role of Environmental Tobacco Smoke (ETS) exposure in domestic environment, the smoking policies adopted at home on urinary excretion of 23 trace elements present in tobacco and/or tobacco smoke (Li, Be, B, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Rb, Sr, Cd, Sn, Sb, Te, Cs, Tl, Pb, Bi, U) among a sample of healthy Italian school-aged children. The levels of monitored trace elements in urine samples from 110 children (5-11years) living in a rural area and recruited in a cross-sectional study were measured via inductively coupled plasma mass spectrometry, while information regarding demographic characteristics and ETS exposure of the participants were obtained from questionnaires. Univariate elaborations evidenced that Co and Mn levels increased in children exposed to ETS in domestic environment, but multiple linear regression analyses revealed the independent effect of the habit of cohabitant(s) smoker(s) of smoking at home when children is present on urinary concentrations of Li, Ti, V, Co, Ga and Sr. Besides, we found significant gender- and age-dependency of some monitored elements: females presented higher Cu and Pb levels, but lower Rb levels respect to males, while age displayed a significant negative independent effect on the Cr, Co, Rb, and Sn concentrations, but positive on Ga levels. Finally, u-creatinine was a significant predictor for almost all the analytes, but not for Mn, Cd, Sb, Ga. PMID:27016686

    Epidermal growth factor receptor (EGFR) and its downstream elements are overexpressed in most cases of the head and neck squamous cell carcinoma. This study investigated the expression pattern of key proteins linked to the EGFR pathway in laryngeal carcinoma patients with a history of cannabis smoking. We selected 83 male glottic cancer patients, aged between 45 to 75 years with three distinct populations-nonsmoker, cigarette smoker, and cannabis smoker. Immunohistochemical staining was performed for EGFR, protein kinase B (PKB or Akt), nuclear factor kappa B p50 (NF-КB), and cyclooxygenase-2 (COX-2) followed by boolean scoring for statistical analysis. Experimental data showed upregulation of the selected EGFR cascade in tumor cells, stromal expression of EGFR, and nuclear localization of COX-2 in metaplastic gland cells of laryngeal cancer tissue sample. Statistical analyses indicated that overexpression of the EGFR cascade is significantly correlated to cannabis smoking. Cannabis smokers had higher expression (p < 0.01) of these onco-proteins with respect to both nonsmokers as well as cigarette smokers. Risk factor analysis showed high risk of these proteins expression in age <60 years (odds ratio (OR) > 1.5) as the lower age group had relatively higher number of cannabis smokers. This study provides evidence for a direct association between cannabis smoking and increased risk of laryngeal cancer. Higher expression of the EGFR cascade in cannabis smokers revealed that cannabis smoking may be a major cause for the early onset of aggressive laryngeal cancer. PMID:25736926

  13. An exploratory examination of the relationships among emotional intelligence, elementary school science teacher self-efficacy, length of teaching experience, race/ethnicity, gender, and age

    The purpose of the study was to examine the relationships among emotional intelligence, teacher self-efficacy, length of teaching experience, and age in a sample of south Texas public school teachers. Additionally, the study examined differences in emotional intelligence between male teachers and female teachers, and among African American, Hispanics, and White teachers. Participants were 180 elementary science teachers from south Texas public schools. The sample was made up of 14 (7.8%) males and 166 (92.2%) females. Regarding race/ethnicity, the study sample consisted of 31 (17.2%) African Americans (3 males and 28 females), 49 (27.2) Hispanics (7 males and 42 females), 98 (54.4%) Whites (3 males and 95 females), and 2 (1.1%) "Other" (1 male and 1 female). Participants ranged in age from 23 years to 65 years. Five hypotheses were proposed and tested to address the relationships under investigation. The study employed a mixed methods---correlational and causal-comparative---research design approach. Three instruments, the Multifactor Emotional Intelligence Scale (Mayer, Caruso, & Salovey, 1999), the Science Teaching Efficacy Beliefs Instrument (Riggs & Enochs, 1990), and a demographics questionnaire were utilized to collect the data. An independent-measures t test, the Pearson r, and the one-way MANOVA were used to analyze the data. A Significant positive relationship was found between "emotional intelligence" and "teacher self-efficacy." Data analyses, however, failed to support hypothesized relationships between "emotional intelligence" and "length of teaching experience," and between "emotional intelligence" and "age". Additionally, statistical analyses of the data collected for this study supported predicted statistically significant differences in "emotional intelligence" between male and female teachers, and among the three race/ethnicity groupings. Based on these findings, recommendations for the application of the construct of "emotional intelligence" in

    The habit of smoking may have automatic behavioral components guided by implicit attitudes. Smokers' attitudes toward smoking should thus be less negative than nonsmokers', so that a salient smoking cue (smell) is able to activate positive aspects of these attitudes. An affective priming task was used to explore this hypothesis. Unexpectedly, smokers and nonsmokers showed equally negative implicit attitudes, irrespective of smell. Smokers exposed to the cigarette smell did, however, display generally slower responses than nonsmokers, suggesting attentional bias. This could have implications for smoking policies in contexts where attentional factors affect performance. PMID:23479305

    This study aims to: (1) describe trajectories in the likelihood of smoking by racial or ethnic group across the transition to adulthood, (2) identify the influence of achieved socioeconomic status (SES) and the nature and timing of adult role transitions, and (3) determine the extent to which achieved SES and adult roles mediate the effects of race and ethnicity on smoking. The analyses use U.S. longitudinal data from the National Longitudinal Study of Adolescent Health (Add Health), which follows a representative national sample over four waves and from ages 11-17 in 1994/95 to 26-34 in 2007/08. Growth curve models compare trajectories of smoking likelihood for white, black, Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native individuals. While whites have higher rates of smoking than blacks and Hispanics during their teen years and 20s, blacks and Hispanics lose their advantage relative to whites as they approach and enter their 30s. American Indian/Alaska Natives show high rates of smoking at earlier ages and an increasing likelihood to smoke. Although life course transitions are influential for smoking prevalence in the overall U.S. population, SES and the nature and timing of adult role transitions account for little of the gap between whites and black, Hispanic, and American Indian/Alaska Native individuals. Racial and ethnic disparities in adult smoking are independent of SES and life transitions, pointing to explanations such as culturally specific normative environments or experiences of discrimination.

    Objectives To estimate the prevalence and distribution of passive smoking in the community population aged 15 years and older in China. Design A systematic review and meta-analysis of cross-sectional studies reporting the prevalence of passive smoking in China and a series of subgroup, trend and sensitivity analyses were conducted in this study. Data source The systematic review and meta-analysis, which included 46 studies with 381 580 non-smokers, estimated the prevalence and distribution of passive smoking in China. All studies were published between 1997 and 2015. Results The pooled prevalence of passive smoking was 48.7% (95% CI 44.8% to 52.5%) and was relatively stable from 1995 to 2013. The prevalence in the subgroups of gender, area, age and time varied from 35.1% (95% CI 31.8% to 38.3%) in the elderly (≥60 years) to 48.6% (95% CI 42.9% to 54.2%) in urban areas. The prevalence was lower in the elderly (≥60 years) than in those between 15 and 59 years of age (OR 1.61, 95% CI 1.44 to 1.81). The difference between females and males in urban and rural areas was not statistically significant (OR: 1.27, 95% CI 0.93 to 1.74 and OR: 1.14, 95% CI 0.82 to 1.58, respectively). In addition, a significantly increasing trend was found among males from 2002 to 2010. Heterogeneity was high in all pooled estimates (I2>98%, p<0.001). Conclusions The high and stable prevalence of passive smoking in China is raising increasing national concern regarding specific research and tobacco control programmes. Attention should be focused on young, middle-aged and male non-smokers regardless of region. PMID:27059465

    The prevalence and associations of bronchial hyperresponsiveness were investigated in a general practice population. The sample was obtained by using every 12th patient on the practice age-sex register, replacing non-responders with corresponding age and sex matched individuals from up to two further 1 in 12 samples. The response rate was 43%; 366 patients were studied. Doubling concentrations of methacholine were given to a maximum of 32 mg/ml or until a 20% fall in forced expiratory volume in one second (FEV1) occurred (provocation concentration, PC20FEV1). Bronchial hyperresponsiveness was defined arbitrarily as a PC20FEV1 of 2 mg/ml or less (or 11 mumol cumulative dose, PD20FEV1). The prevalence of bronchial hyperresponsiveness was 23%. Bronchial hyperresponsiveness was not associated with age but was more prevalent in women than men (31%:13%). It was also more common in those who had ever wheezed (39%) and in those who had had an attack of rhinitis in the preceding month (45%, p less than 0.1), in atopic individuals (30%), and in smokers (32%), but it was not associated with cough or dyspnoea. There was a positive correlation between PC20FEV1 and resting FEV1 (r = 0.288) and a negative correlation between PC20FEV1 and mean daily peak flow variability (r = -0.356). Stepwise binary logistic regression analysis showed significant independent effects on PC20FEV1 for mean daily peak flow variability, gender, number of positive skin test responses, resting FEV1, and mean histamine skin weal area, but no relation with smoking or mean allergen weal area. The prevalence of bronchial hyperresponsiveness was much higher than the prevalence of diagnosed asthma in the practice in 1984 (4.9%). Analysis of case notes of 169 individuals showed that those with bronchial hyperresponsiveness had not attended the practice more frequently for respiratory complaints during the previous five years.

    2011-01-01

    Background Serum selenium level (s-Se) has been associated with prostate cancer (PrCa) risk. We investigated the relation between s-Se, smoking and non-screening detected PrCa and explored if polymorphisms in two DNA repair genes: OGG1 and MnSOD, influenced any effect of s-Se. Methods ULSAM, a population based Swedish male cohort (n = 2322) investigated at age 50 for s-Se and s-Se influencing factors: serum cholesterol, erythrocyte sedimentation rate and smoking habits. At age 71 a subcohort, (n = 1005) was genotyped for OGG1 and MnSOD polymorphisms. Results In a 34-year-follow-up, national registries identified 208 PrCa cases further confirmed in medical records. Participants with s-Se in the upper tertile had a non-significantly lower risk of PrCa. Smokers with s-Se in the two lower tertiles (≤80 μg/L) experienced a higher cumulative incidence of PrCa than smokers in the high selenium tertile (Hazard Ratio 2.39; 95% CI: 1.09-5.25). A high tertile selenium level in combination with non-wt rs125701 of the OGG1 gene in combination with smoking status or rs4880 related variation of MnSOD gene appeared to protect from PrCa. Conclusions S-Se levels and smoking habits influence long-term risk of PrCa. Smoking as a risk factor for PrCa in men with low s-Se is relevant to explore further. Exploratory analyses of variations in OGG1 and MnSOD genes indicate that hypotheses about patterns of exposure to selenium and smoking combined with data on genetic variation in genes involved in DNA repair can be valuable to pursue.

    Introduction Cigarette smoking may exacerbate and cause psoriasis. Moreover, smokers are more likely to develop insulin resistance and metabolic syndrome (MS). Aim To assess the prevalence of MS and its components in patients with psoriasis, who smoke, compared with the general Polish population of smokers. Material and methods We studied 29 patients with psoriasis (female = 9, male = 20), smokers, aged 30 to 49 years. Metabolic syndrome and its components were assessed using the IDF definition and compared to the results obtained in a representative sample of adult Poles in the NATPOL 2011 study in the same age group, including smokers. Results The results have shown that patients with psoriasis are more likely to be smokers (p < 0.0034) and the frequency of smoking in men is approximately 25% higher than in males of the control group (p < 0.0017). The prevalence of MS in patients with psoriasis who smoke was 27.58% and in the control group 25.2% (p > 0.05). Mean body mass index was 26.07 kg/m2 in psoriasis patients and 25.59 kg/m2 in the control group (p > 0.05), and abdominal obesity was 88.82 cm and 90.02 cm (p > 0.05), respectively. There were no differences in hypertension (34.48% vs. 31.6%, p < 0.05) and mean HOMA-IR (1.80 vs. 1.77, p > 0.05). In lipid parameters, the differences were observed only in women with psoriasis – higher levels of HDL, triglycerides and ApoB/ApoA1 index compared with addicted women in the control group. Conclusions Men with psoriasis are more often addicted to smoking. Women with psoriasis who smoke have often disturbances of the lipid profile. PMID:26759540

    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.

    Introduction This study assessed the prevalence and correlates of secondhand smoke (SHS) exposure and attitudes toward smoke-free workplaces among employed U.S. adults. Methods Data came from the 2009–2010 National Adult Tobacco Survey, a landline and cellular telephone survey of adults aged ≥18 years in the United States and the District of Columbia. National and state estimates of past 7-day workplace SHS exposure and attitudes toward indoor and outdoor smoke-free workplaces were assessed among employed adults. National estimates were calculated by sex, age, race/ethnicity, education, annual household income, sexual orientation, U.S. region, and smoking status. Results Among employed adults who did not smoke cigarettes, 20.4% reported past 7-day SHS exposure at their workplace (state range: 12.4% [Maine] to 30.8% [Nevada]). Nationally, prevalence of exposure was higher among males, those aged 18–44 years, non-Hispanic Blacks, Hispanics, and non-Hispanic American Indians/Alaska natives compared to non-Hispanic Whites, those with less education and income, those in the western United States, and those with no smoke-free workplace policy. Among all employed adults, 83.8% and 23.2% believed smoking should never be allowed in indoor and outdoor areas of workplaces, respectively. Conclusions One-fifth of employed U.S. adult nonsmokers are exposed to SHS in the workplace, and disparities in exposure exist across states and subpopulations. Most employed adults believe indoor areas of workplaces should be smoke free, and nearly one-quarter believe outdoor areas should be smoke free. Efforts to protect employees from SHS exposure and to educate the public about the dangers of SHS and benefits of smoke-free workplaces could be beneficial. PMID:24812025

    On November 17th 2009 we used a Twin Otter aircraft outfitted with an airborne Fourier transform infrared spectrometer (AFTIR), aerosol mass spectrometer (AMS), single particle soot photometer (SP2), nephelometer, Licor CO2 analyzer, and a chemiluminescence ozone instrument to measure the initial emissions from a 100 hectare prescribed fire in chaparral fuels on the central coast of California, U.S.A. We also measured the post emission chemical changes in the isolated downwind plume for a distance corresponding to about 4.5 hours of smoke aging. The light scattering to CO2 ratio increased by a factor of ~2.7 over 4 hours: similar to observations in a biomass burning plume in Mexico where significant secondary formation of organic aerosol (OA) was confirmed by AMS. However, in the California plume, a decrease in OA was observed by AMS along with a concurrent increase in the fraction of thickly coated particles as measured by the SP2. Decreasing OA accompanied by increased scattering/coating may be explained by a combination of coagulation and evaporation processes. The latter may have been promoted in the California plume because it diluted in a “clean,” low relative humidity (11-26%) environment compared to the Mexican plume. AFTIR measured significant changes in gas phase constituents. The molar ratio of O3 to CO increased from approximately zero to 0.102 in 4.5 hours. Large growth factors for organic acids were also observed over the same aging period: acetic acid and formic acid increased by factors of 1.68 and 7.13, respectively. Inorganic species measured by the AMS also increased with plume aging. While the mass ratio of NH4+ to CO2 increased by ~2.3 x 10-4 in about 4 hours, the NH3/CO2 decreased by ~4.1 x 10-4, with ammonium accounting for ~55% of the gaseous ammonia lost (by mass). Conversion of NOx to PAN was observed coincident with formation of particle nitrate. A rapid decay in C2H4 was consistent with an in-plume average OH of ~5.40 x 106 molecules

    This study investigated the effectiveness of two components of a smoking cessation intervention: a reading manual and a series of televised programs. Female smokers in the Chicago metropolitan area with a high school education or less were interviewed at 4 different times: baseline, immediate postintervention, and 6 and 12 months. We examined the effects of several baseline measures (race, age, number of cigarettes smoked, and stage of readiness to change) and exposure to the intervention components on subsequent stage of change. Race, baseline smoking rate, baseline stage, and exposure to both intervention components had direct effects on stage at immediate postintervention, with both intervention components increasing readiness to quit. Furthermore, exposure to the manual interacted with baseline stage, such that the manual benefited women at earlier stages more than women at later stages. Effects of both components were sustained at 6 months, and the effects of the manual were sustained at 12 months. PMID:11469117

    Nicotine dependence is moderately heritable, but identified genetic associations explain only modest portions of this heritability. We analyzed 3,369 SNPs from 349 candidate genes, and investigated whether incorporation of SNP-by-environment interaction into association analyses might bolster gene discovery efforts and prediction of nicotine dependence. Specifically, we incorporated the interaction between allele count and age-at-onset of regular smoking (AOS) into association analyses of nicotine dependence. Subjects were from the Collaborative Genetic Study of Nicotine Dependence, and included 797 cases ascertained for Fagerström nicotine dependence, and 811 non-nicotine dependent smokers as controls, all of European descent. Compared with main-effect models, SNP x AOS interaction models resulted in higher numbers of nominally significant tests, increased predictive utility at individual SNPs, and higher predictive utility in a multi-locus model. Some SNPs previously documented in main-effect analyses exhibited improved fits in the joint-analysis, including rs16969968 from CHRNA5 and rs2314379 from MAP3K4. CHRNA5 exhibited larger effects in later-onset smokers, in contrast with a previous report that suggested the opposite interaction (Weiss et al, PLOS Genetics, 4: e1000125, 2008). However, a number of SNPs that did not emerge in main-effect analyses were among the strongest findings in the interaction analyses. These include SNPs located in GRIN2B (p=1.5 × 10−5), which encodes a subunit of the NMDA receptor channel, a key molecule in mediating age-dependent synaptic plasticity. Incorporation of logically chosen interaction parameters, such as AOS, into genetic models of substance-use disorders may increase the degree of explained phenotypic variation, and constitutes a promising avenue for gene-discovery.

    1. We studied 37 healthy men at rest in the supine. position to examine the effect of ageing, smoking and physical training of beta 2-adrenoceptor function, plasma catecholamines and the proportions of various lymphocyte subsets. 2. In 14 young subjects the proportion of natural killer cells was correlated with cAMP production in lymphocytes and inversely correlated with plasma noradrenaline level. 3. In 16 elderly non-smokers plasma noradrenaline was negatively correlated with the natural killer cell subset CD3-CD16+. Lymphocyte cAMP responses did not differ between young and elderly non-smokers, whereas plasma noradrenaline increased slightly but significantly with age. Physical training did not influence either plasma noradrenaline or adrenaline at rest or cAMP in lymphocytes. 4. In seven elderly long-term smokers cAMP production and the viability of lymphocytes were reduced. Plasma noradrenaline attained its highest values in long-term smokers. 5. It is concluded that cAMP production and plasma noradrenaline are related to lymphocyte subset composition. The greater the proportion of natural killer cells and related subsets, the higher is cAMP production and the lower is plasma noradrenaline. Thus, the inverse correlation between lymphocyte cAMP and plasma noradrenaline is indirect and most likely mediated by variability in lymphocyte subset composition. In elderly subjects, reduced cAMP production was observed in long-term smokers, and this abnormality was probably due to a reduced viability of lymphocytes and especially of natural killer cells. The negative correlation between the proportion of natural killer cells and plasma noradrenaline at rest contracts with a well-known mobilizing effect of adrenaline on natural killer cells.

    This study examines how the intersecting consequences of race-ethnicity, gender, socioeconomics status (SES), and age influence health inequality. We draw on multiple-hierarchy stratification and life course perspectives to address two main research questions. First, does racial-ethnic stratification of health vary by gender and/or SES? More specifically, are the joint health consequences of racial-ethnic, gender, and socioeconomic stratification additive or multiplicative? Second, does this combined inequality in health decrease, remain stable, or increase between middle and late life? We use panel data from the Health and Retirement Study (N = 12,976) to investigate between- and within-group differences in in self-rated health among whites, blacks, and Mexican Americans. Findings indicate that the effects of racial-ethnic, gender, and SES stratification are interactive, resulting in the greatest racial-ethnic inequalities in health among women and those with higher levels of SES. Furthermore, racial-ethnic/gender/SES inequalities in health tend to decline with age. These results are broadly consistent with intersectionality and aging-as-leveler hypotheses. PMID:27284076

    We examined the effects of Hurricane Katrina on disability-related measures of health among adults from New Orleans, U.S.A., in the year after the hurricane, with a focus on differences by age, race, and sex. Our analysis used data from the American Community Survey to compare disability rates between the pre-Katrina population of New Orleans with the same population in the year after Katrina (individuals were interviewed for the study even if they relocated away from the city). The comparability between the pre- and post-Katrina samples was enhanced by using propensity weights. We found a significant decline in health for the adult population from New Orleans in the year after the hurricane, with the disability rate rising from 20.6% to 24.6%. This increase in disability reflected a large rise in mental impairments and, to a lesser extent, in physical impairments. These increases were, in turn, concentrated among young and middle-aged black females. Stress-related factors likely explain why young and middle-aged black women experienced worse health outcomes, including living in dwellings and communities that suffered the most damage from the hurricane, household breakup, adverse outcomes for their children, and higher susceptibility.

    Secondhand smoke (SHS) is a major risk factor for poor health outcomes among women in China, where proportionately few women smoke. This is especially the case as it pertains to women’s reproductive health, specifically migrant women who are exposed to SHS more than the population at large. There are several factors which may increase migrant women’s risk of SHS exposure. This paper aims to investigate the prevalence and associated factors of SHS exposure among internal Chinese migrant women of reproductive age. The data used were derived from the 2014 Chinese Labor Dynamic Survey, a national representative panel survey. The age-adjusted rate of SHS exposure of women of reproductive age with migration experience was of 43.46% (95% CI: 40.73%–46.40%), higher than those without migration experience (35.28% (95% CI: 33.66%–36.97%)). Multivariate analysis showed that participants with a marital status of “Widowed” had statistically lower exposure rates, while those with a status of “Cohabitation” had statistically higher exposure. Those with an undergraduate degree or above had statistically lower SHS exposure. Those with increasing levels of social support, and those who currently smoke or drink alcohol, had statistically higher SHS exposure. Participants’ different work-places had an effect on their SHS exposure, with outdoor workers statistically more exposed. Our findings suggest that urgent tobacco control measures should be taken to reduce smoking prevalence and SHS exposure. Specific attention should be paid to protecting migrant women of reproductive age from SHS. PMID:27043604

    Treatment of acute ST-segment elevation myocardial infarction (STEMI) has dramatically changed over the past 2 decades. The goal of this study was to determine trends in the mortality of patients with acute STEMIs in the United States over a 16-year period (1988 to 2004) on the basis of gender, race, infarct location, and co-morbidities. The Nationwide Inpatient Sample database was used to analyze the age-adjusted mortality rates for STEMI from 1988 to 2004 for inpatients age >40. International Classification of Diseases, Ninth Revision, Clinical Modification codes consistent with acute STEMI were used. The Nationwide Inpatient Sample database contained a total of 1,316,216 patients who had diagnoses of acute STEMIs from 1988 to 2004. The mean age of these patients was 66.92 +/- 12.82 years. A total of 163,915 hospital deaths occurred during the study period. From 1988, the age-adjusted mortality rate decreased gradually for all acute STEMIs for the entire study period (in 1988, 406.86 per 100,000, 95% confidence interval 110.25 to 703.49; in 2004, 286.02 per 100,000, 95% confidence interval 45.21 to 526.84). Furthermore, unadjusted mortality decreased from 15% in 1988 to 10% in 2004 (p <0.01). This decrease was similar between the genders, among most ethnicities, and in patients with diabetes and those with congestive heart failure. However, women and African Americans had higher rates of acute STEMI-related mortality compared to men and Caucasians over the years studied. In conclusion, age-adjusted mortality from acute STEMIs has significantly decreased over the past 16 years, with persistent higher mortality rates in women and African Americans the study period.

    The Veterans Aging Cohort Study (VACS) Index was developed as a risk index for health outcomes in HIV, and it has been consistently associated with mortality. It shows a significant, yet relatively weak, association with neurocognitive impairment, and little is known about its utility among ethnic/racial minority groups. We examined whether the association between the VACS Index and neurocognition differed by ethnic/racial group. Participants included 674 HIV-infected individuals (369 non-Hispanic whites, 111 non-Hispanic blacks, and 194 Hispanics). Neurocognitive function was assessed via a comprehensive battery. Scaled scores for each neurocognitive test were averaged to calculate domain and global neurocognitive scores. Models adjusting for demographics and HIV disease characteristics not included in the VACS Index showed that higher VACS Index scores (indicating poorer health) were significantly associated with worse global neurocognition among non-Hispanic whites. This association was comparable in non-Hispanic blacks, but nonsignificant among Hispanics (with similar results for English and Spanish speaking). We obtained comparable findings in analyses adjusting for other covariates (psychiatric and medical comorbidities and lifestyle factors). Analyses of individual neurocognitive domains showed similar results in learning and delayed recall. For other domains, there was an effect of the VACS Index and no significant interactions with race/ethnicity. Different components of the VACS Index were associated with global neurocognition by race/ethnicity. In conclusion, the association between the VACS Index and neurocognitive function differs by ethnic/racial group. Identifying key indicators of HIV-associated neurocognitive impairment by ethnic/racial group might play an important role in furthering our understanding of the biomarkers of neuroAIDS.

    An 86-year-old man became a double champion in the European championship for road running in 2009. He won the 10-km road run with a time of 58:01 minutes, setting a new European record for men aged 85 and older. Two days later, he became a European champion in the same age group for the half-marathon, with a time of 2:17 hours. He started his running career at the age of 64 years and has trained for about an hour three times a week every year since. During these 22 years, he has performed several road runs each year, ranging from 2.5 to 10 km, and also completed a number of half-marathons. Although his running speeds had progressively slowed since the age of 64, there was an increased rate of decline at the age of 82. This man's outstanding performance should encourage other master runners to continue running and competing past the age of 85. PMID:20671823

    The improved characterisation of risk factors for rheumatoid arthritis (RA) suggests they could be combined to identify individuals at increased disease risks in whom preventive strategies may be evaluated. We aimed to develop an RA prediction model capable of generating clinically relevant predictive data and to determine if it better predicted younger onset RA (YORA). Our novel modelling approach combined odds ratios for 15 four-digit/10 two-digit HLA-DRB1 alleles, 31 single nucleotide polymorphisms (SNPs) and ever-smoking status in males to determine risk using computer simulation and confidence interval based risk categorisation. Only males were evaluated in our models incorporating smoking as ever-smoking is a significant risk factor for RA in men but not women. We developed multiple models to evaluate each risk factor's impact on prediction. Each model's ability to discriminate anti-citrullinated protein antibody (ACPA)-positive RA from controls was evaluated in two cohorts: Wellcome Trust Case Control Consortium (WTCCC: 1,516 cases; 1,647 controls); UK RA Genetics Group Consortium (UKRAGG: 2,623 cases; 1,500 controls). HLA and smoking provided strongest prediction with good discrimination evidenced by an HLA-smoking model area under the curve (AUC) value of 0.813 in both WTCCC and UKRAGG. SNPs provided minimal prediction (AUC 0.660 WTCCC/0.617 UKRAGG). Whilst high individual risks were identified, with some cases having estimated lifetime risks of 86%, only a minority overall had substantially increased odds for RA. High risks from the HLA model were associated with YORA (P<0.0001); ever-smoking associated with older onset disease. This latter finding suggests smoking's impact on RA risk manifests later in life. Our modelling demonstrates that combining risk factors provides clinically informative RA prediction; additionally HLA and smoking status can be used to predict the risk of younger and older onset RA, respectively.

    This study analyzes the relationships of cigarette smoking and smoking histories to marital and parental status. Data from a large, representative sample of U.S. adults in 1985 were analyzed separately for white men, white women, black men, and black women, with controls for age, education, and marital status included in the analyses. Divorced and separated adults were the most likely to be current smokers or ever to have adopted smoking; currently married adults and widowed adults were intermediate; and never married adults were the least likely to be current smokers or ever to have adopted smoking. (There were some exceptions to these patterns for never married and widowed blacks). The differences in smoking adoption had begun during adolescence, before the usual age of marriage, which suggests that the differences in smoking, adoption were not caused by marriage or divorce. Rather, it appears that personal characteristics or early experiences influenced both the likelihood of smoking adoption and the likelihood of marriage or divorce. Currently married adults were more likely to have quit smoking than never married, divorced and separated, or widowed adults. It may be that the social support provided by marriage increases smoking cessation. In contrast to the strong relationships between marital status and smoking, relationships between parental status and smoking were relatively weak and variable. Among white women, mothers of preschoolers were less likely to be smokers than women without children. The mothers of preschoolers were more likely to have quit smoking, possibly as a result of increased smoking cessation during pregnancy. PMID:2787160

    The aim of this study was to test whether maternal smoking-specific communication and parental smoking related to smoking cognitions (i.e. attitude, self-efficacy and social norm) derived from the Theory of Planned Behaviour in association with smoking onset during preadolescence. A total of 1478 pairs of mothers and children participated (mean age: 10.11; standard deviation = 0.78). Structural equation models in Mplus were used to examine whether smoking-specific communication influences children's smoking cognitions, which in turn, affect smoking onset. A positive association was found between pro-smoking attitudes and smoking onset. Smoking-specific communication and parental smoking were related to smoking cognitions. Specifically, frequency of communication was negatively associated with pro-smoking attitudes, social norms of mother and best friend. Quality of communication related negatively to pro-smoking attitudes and positively to self-efficacy and norms of friends. Parental smoking was positively associated with pro-smoking attitudes and norms of mother and (best) friends. Additionally, more frequent communication and higher levels of parental smoking were associated with higher smoking onset. In conclusion, smoking-specific communication and parental smoking were associated with smoking cognitions and smoking onset. Already during preadolescence, parents contribute to shaping the smoking cognitions of their children, which may be predictive of smoking later in life. PMID:22519750

    The NASA Goddard Earth Observing System version 5 (GEOS-5) Earth system model, which includes an online aerosol module, provided chemical and weather forecasts during the SEAC4RS field campaign. For post-mission analysis, we have produced a high resolution (25 km) meteorological and aerosol reanalysis for the entire campaign period. In addition to the full meteorological observing system used for routine NWP, we assimilate 550 nm aerosol optical depth (AOD) derived from MODIS (both Aqua and Terra satellites), ground-based AERONET sun photometers, and the MISR instrument (over bright surfaces only). Daily biomass burning emissions of CO, CO2, SO2, and aerosols are derived from MODIS fire radiative power retrievals. We have also introduced novel smoke "age" tracers, which provide, for a given time, a snapshot histogram of the age of simulated smoke aerosol. Because GEOS-5 assimilates remotely sensed AOD data, it generally reproduces observed (column) AOD compared to, for example, the airborne 4-STAR instrument. Constraining AOD, however, does not imply a good representation of either the vertical profile or the aerosol microphysical properties (e.g., composition, absorption). We do find a reasonable vertical structure for aerosols is attained in the model, provided actual smoke injection heights are not much above the planetary boundary layer, as verified with observations from DIAL/HRSL aboard the DC8. The translation of the simulated aerosol microphysical properties to total column AOD, needed in the aerosol assimilation step, is based on prescribed mass extinction efficiencies that depend on wavelength, composition, and relative humidity. Here we also evaluate the performance of the simulated aerosol speciation by examining in situ retrievals of aerosol absorption/single scattering albedo and scattering growth factor (f(RH)) from the LARGE and AOP suite of instruments. Putting these comparisons in the context of smoke age as diagnosed by the model helps us to

    Objective The objective of this study was to determine whether maternal plasma concentrations of soluble α-klotho are different between women with microbial invasion of the intra-amniotic cavity (MIAC) and those without MIAC among preterm labor and intact membranes (PTL) or preterm prelabor rupture of membranes (pPROM). Methods A cross-sectional study was conducted to include women in the following groups:1) PTL with MIAC (n=14); 2) PTL without MIAC (n=79); 3) pPROM with MIAC (n=30); and 4) pPROM without MIAC (n=33). MIAC was defined as a positive amniotic fluid culture for microorganisms (aerobic/anaerobic bacteria or genital mycoplasmas). Amniotic fluid samples were obtained within 48 hours from maternal blood collection. Plasma concentration of soluble α-klotho was determined by ELISA. Results 1) The median plasma concentration (pg/mL) of soluble α-klotho was significantly lower in patients with MIAC than in those without MIAC (787.0 vs. 1117.8; p <0.001); 2) Among patients with PTL, those with MIAC had a lower median plasma concentration (pg/mL) of soluble α-klotho than those without MIAC (787.0 vs. 1138.9; p=0.007); 3) Among patients with pPROM, those with MIAC had a lower median plasma concentration (pg/mL) of soluble α-klotho than those without MIAC (766.4 vs. 1001.6; p=0.045); 4) There was no significant difference in the median plasma concentration of soluble α-klotho between PPROM without MIAC and PTL without MIAC (1001.6 pg/mL vs. 1138.9 pg/mL, respectively; p=0.5); 5) After adjustment for potential confounders (maternal age, tobacco use, gestational age at venipuncture), soluble α-klotho remained significantly associated with MIAC (p= 0.02); and 6) Among patients without MIAC, smoking was significantly associated with a lower median plasma concentration soluble α-klotho than in non-smokers (794.2 pg/mL vs. 1382.0 pg/mL, respectively; p<0.001); however, this difference was not observed in patients with MIAC.

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

    Maternal smoking during pregnancy is one proposed risk factor for gastroschisis, but reported associations have been modest, suggesting that differences in genetic susceptibility might play a role. We included 108 non-Hispanic white and 62 Hispanic families who had infants with gastroschisis, and 1,147 non-Hispanic white and 337 Hispanic families who had liveborn infants with no major structural birth defects (controls) in these analyses. DNA was extracted from buccal cells collected from infants and mothers, and information on periconceptional smoking history was obtained from maternal interviews, as part of the National Birth Defects Prevention Study. We analyzed five polymorphisms in three genes that code for enzymes involved in metabolism of some cigarette smoke constituents (CYP1A1, CYP1A2, and NAT2). Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) independently for maternal smoking and maternal and infant gene variants, and to assess joint associations of maternal smoking and maternal or infant gene variants with gastroschisis. In analyses adjusted for maternal age at delivery and stratified by maternal race-ethnicity, we identified three suggestive associations among 30 potential associations with sufficient numbers to calculate ORs: CYP1A1*2A for non-Hispanic white mothers who smoked periconceptionally (aOR = 0.38, 95% CI 0.15-0.98), and NAT2*6 for Hispanic non-smoking mothers (aOR = 2.17, 95% CI 1.12-4.19) and their infants (aOR = 2.11, 95% CI 1.00-4.48). This analysis does not support the occurrence of effect modification between periconceptional maternal smoking and most of the xenobiotic metabolizing enzyme gene variants assessed. PMID:24668907

    Introduction: Evidence suggests that hookah smoking is growing among adolescents, particularly among those with a history of cigarette smoking, and is an emerging public health concern. We examined hookah use and its correlates among a sample of adolescents who have ever smoked and may be considered high risk for hookah use. Methods: We examined differences between hookah users and nonusers among a cohort of 951 adolescents (75.3% of the baseline sample, mean age 17.6 years at 24 months), consisting exclusively of youth who reported ever smoking cigarettes who were participating in a longitudinal study of adolescent smoking predictors and patterns. Ever and 30-day hookah use were assessed at 24 months. Results: Of the 951 participants, 58.5% reported ever use and 30.2% reported smoking hookah at least 1 day in the past 30 days. Multivariate logistic regression analyses found that 30-day hookah use was associated with sex (p < .05); race (p < .001); current cigarette (p < .0001), cigar (p < .01), kretek (p < .05), and alcohol use (p < .01); and attending a hookah bar, lounge, or restaurant (p < .001). Participants who were male, White, and were concurrent users of multiple tobacco products and other substances had increased odds of 30-day hookah use. Conclusions: Prevalence of hookah use is high among youth who have already tried cigarette smoking and is associated with a variety of tobacco and other substance use behaviors. Evidence-based programs may be needed to prevent initiation of or reduce Hookah smoking, as well as address cooccurring problem behaviors, to lessen the health risks associated with use among adolescents.

  3. Smoking and adolescent health.

    PubMed

    Park, Sang-Hee

    2011-10-01

    With the Westernization and opening of our society, adolescents' smoking is increasing and being popularized. Many adolescents start smoking at an early age out of curiosity and venturesomeness, and earlier start of smoking makes it more difficult to quit smoking. Adolescents' habitual smoking not only becomes a gateway to all kinds of substance abuse but also causes various health problems including upper respiratory infection, immature lung development, reduced maximum vital capacity, and lung cancer. Therefore, it is quite important to prevent adolescents from smoking. The lowering of adolescents' smoking rate cannot be achieved only through social restrictions such as stereotyped education on the harms of smoking and ID checking. In order to lower adolescents' smoking rate substantially, each area of society should develop standardized programs and make related efforts. As adolescents' smoking is highly influenced by home environment or school life, it is necessary to make efforts in effective education and social reinforcement in school, to establish related norms, and to execute preventive education using peer groups. When these efforts are spread throughout society in cooperation with homes and communities, they will be helpful to protect adolescents' health and improve their quality of life. PMID:22232621

    Although many states in the US have raised cigarette excise taxes in recent years, the size of these increases have been fairly modest (resulting in a 15% increase in the per pack purchase price), and their impact on adult smoking prevalence is likely insufficient to meet Healthy People 2010 objectives. This paper presents the results of a 75-year dynamic simulation model comparing the long-term health benefits to society of various levels of tax increase to a viable alternative: limiting youth access to cigarettes by raising the legal purchase age to 21. If youth smoking initiation is delayed as assumed in the model, increasing the smoking age would have a minimal immediate effect on adult smoking prevalence and population health, but would affect a large drop in youth smoking prevalence from 22% to under 9% for the 15-17-year-old age group in 7 years (by 2010)-better than the result of raising taxes to increase the purchase price of cigarettes by 100%. Reducing youth initiation by enforcing a higher smoking age would reduce adult smoking prevalence in the long-term (75 years in the future) to 13.6% (comparable to a 40% tax-induced price increase), and would produce a cumulative gain of 109 million QALYs (comparable to a 20% price increase). If the political climate continues to favor only moderate cigarette excise tax increases, raising the smoking age should be considered to reduce the health burden of smoking on society. The health benefits of large tax increases, however, would be greater and would accrue faster than raising the minimum legal purchase age for cigarettes. PMID:16698112

    The article brings together the fields of curriculum studies, history of education, and ethnic studies to chart a transnational history of race, empire, and curriculum. Drawing from a larger study on the history of education in the Philippines under U.S. rule in the early 1900s, it argues that race played a pivotal role in the discursive…

    Adjuvant trastuzumab for human epidermal growth factor receptor-2 (HER2)-positive breast cancer is highly efficacious regardless of age. Recent data suggested that many older patients with HER2-positive disease do not receive adjuvant trastuzumab. Nevertheless, some of this 'under-treatment' may be clinically appropriate. We used Surveillance, Epidemiology and End Results (SEER)-Medicare data to identify patients aged ≥ 66 with stage ≥ Ib-III, HER2-positive breast cancer diagnosed during 2010-2011 (HER2 status available) who did not have a history of congestive heart failure. We described all systemic treatments received and sociodemographic and clinical characteristics associated with treatment patterns. Among 770 women 44.4 % did not receive trastuzumab, including 21.8 % who received endocrine therapy only, 6.3 % who received chemotherapy (±endocrine therapy) and 16.2 % who did not receive any systemic therapy. In addition to age and grade, race was strongly associated with non-use of trastuzumab (64.4 % of Non-Hispanic blacks vs. 43.6 % of whites did not receive trastuzumab, adjusted ORNon-Hispanic black vs. white = 3.14, 95 %CI = 1.38-7.17), and many patients with stage III disease did not receive trastuzumab. Further, 16.2 % of patients did not receive any systemic treatment and this occurred more frequently for black patients. Over 40 % of older patients with indication to receive adjuvant trastuzumab did not receive it and nearly 20 % of these patients did not receive any other treatment. Although treatment omission may be appropriate in some cases, we observed concerning differences in trastuzumab receipt, particularly for black women. Strategies to optimize care for older patients and to eliminate treatment disparities are urgently needed. PMID:27484879

    It is recommended that providers advise cessation to their patients who smoke. However, patients' reports of cessation advice indicate disparities based on patients' race, gender, age, and smoking level. Providers' reports do not corroborate these disparities. We investigated whether smokers who receive their care in a community health center recalled their providers advising them to quit smoking when their providers documented such advice. We examined 219 patient-provider dyads to assess factors associated with lack of agreement between providers' documentation and patient recall. Patients were asked to recall any provider advice to quit smoking in the post 2 years. After every visit, providers completed a form to record the content of the visit. Most of the patients were African American, married, and uninsured. Sixty-eight percent of the dyads agreed in their documentation/recall. Patient race was the only factor associated with lack of agreement; African-American patients were more likely than white patients to provide discrepant reports. Although this study can not disentangle the racial difference in patient-provider recall/documentation, results may indicate an important area in which health disparities exist. Future studies should address the dynamics of patient-provider communication about smoking cessation, especially in populations that include ethnically diverse patients. PMID:12069216

    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.

    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 horrorfilms, 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 To assess the predictors of intentions to quit smoking in a community sample of Aboriginal smokers of reproductive age, in whom smoking prevalence is slow to decline. Design, setting and participants A cross-sectional survey involved 121 Aboriginal smokers, aged 18–45 years from January to May 2014, interviewed at community events on the Mid-North Coast NSW. Qualitative and quantitative data were collected on smoking and quitting attitudes, behaviours and home smoking rules. Perceived efficacy for quitting, and perceived threat from smoking, were uniquely assessed with a validated Risk Behaviour Diagnosis (RBD) Scale. Main outcome measures Logistic regression explored the impact of perceived efficacy, perceived threat and consulting previously with a doctor or health professional (HP) on self-reported intentions to quit smoking, controlling for potential confounders, that is, protection responses and fear control responses, home smoking rules, gender and age. Participants’ comments regarding smoking and quitting were investigated via inductive analysis, with the assistance of Aboriginal researchers. Results Two-thirds of smokers intended to quit within 3 months. Perceived efficacy (OR=4.8; 95% CI 1.78 to 12.93) and consulting previously with a doctor/HP about quitting (OR=3.82; 95% CI 1.43 to 10.2) were significant predictors of intentions to quit. ‘Smoking is not doing harm right now’ was inversely associated with quit intentions (OR=0.25; 95% CI 0.08 to 0.8). Among those who reported making a quit attempt, after consulting with a doctor/HP, 40% (22/60) rated the professional support received as low (0–2/10). Qualitative themes were: the negatives of smoking (ie, disgust, regret, dependence and stigma), health effects and awareness, quitting, denial, ‘smoking helps me cope’ and social aspects of smoking. Conclusions Perceived efficacy and consulting with a doctor/HP about quitting may be important predictors of intentions to quit

    This study examined the effects of providing lung age, as assessed via a lung function test (spirometry), and respiratory symptoms feedback on college smokers' perceived smoking-related risks, worries and desire to quit. We also investigated whether smokers reacted defensively to this feedback. One hundred and twenty-four smokers were randomized to either receive lung age and respiratory symptoms feedback (intervention group) or a brochure containing facts about smoking only (control group). Perceived risks, worries and desire to quit did not differ between groups. In both groups, worries, but not perceived risks, were correlated with a stronger desire to quit. With increasing lung age, smokers rated the feedback as less relevant and reported exerting less effort breathing in and out while undergoing spirometry. The latter two outcomes were associated with less worry. These findings suggest that lung age and respiratory symptoms feedback does not translate readily into appreciable changes in motivation to quit as well as do other often reported mediators of change (e.g., perceived risks and worries).

    Objectives To compare individual with community risk factors for adolescent smoking. Design A cross-sectional observational study with multivariate analysis. Setting National telephone survey. Participants 3646 US adolescents aged 13–18 years in 2007 recruited through a random digit-dial survey. Outcome measures Ever tried smoking and, among experimental smokers, smoking intensity (based on smoking in past 30 days). Results One-third of participants (35.6%, N=1297) had tried smoking. After controlling for individual risk factors, neither tobacco outlet density nor proximity were associated with tried smoking or smoking intensity. Associations with trying smoking included age (adjusted OR (AOR)=1.23, 95% CI 1.16 to 1.31), lower socioeconomic status (AOR=0.82, 95% CI 0.74 to 0.91), sibling smoking (AOR=2.13, 95% CI 1.75 to 2.59), friend smoking (AOR=2.60, 95% CI 2.19 to 3.10 for some and AOR=7.01, 95% CI 5.05 to 9.74 for most), movie smoking exposure (AOR=2.66, 95% CI 1.95 to 3.63), team sports participation (AOR=0.69, 95% CI 0.54 to 0.89) and sensation seeking (AOR=7.72, 95% CI 5.26 to 11.34). Among experimental smokers, age (AOR=1.32, 95% CI 1.21 to 1.44), minority status (AOR=0.48, 95% CI 0.30 to 0.79 for Black; AOR=0.46, 95% CI 0.31 to 0.69 for Hispanic; AOR=0.53, 95% CI 0.43 to 0.85 for mixed race/other), friend smoking (AOR=3.37, 95% CI 2.37 to 4.81 for some; AOR=20.27, 95% CI 13.22 to 31.08 for most), team sports participation (AOR=0.38, 95% CI 0.26 to 0.55) and sensation seeking (AOR=6.57, 95% CI 3.71 to 11.64) were associated with smoking intensity. Conclusions The study suggests that interventions and policies to prevent and reduce youth smoking should focus on individual risk factors for smoking, including supporting participation in team sports, minimising exposure to movie smoking, addressing the social influence of friend smoking and addressing experience seeking among high sensation-seekers.

    Identification of modifiable behaviors is important for pediatric weight management and obesity prevention programs. This study examined obesogenic behaviors in children with obesity in a Northern California obesity intervention program using data from a parent/teen-completed intake questionnaire covering dietary and lifestyle behaviors (frequency of breakfast, family meals, unhealthy snacking and beverages, fruit/vegetable intake, sleep, screen time, and exercise). Among 7956 children with BMI ≥ 95th percentile, 45.5% were females and 14.2% were 3–5, 44.2% were 6–11, and 41.6% were 12–17 years old. One-quarter (24.9%) were non-Hispanic white, 11.3% were black, 43.5% were Hispanic, and 12.0% were Asian/Pacific Islander. Severe obesity was prevalent (37.4%), especially among blacks, Hispanics, and older children, and was associated with less frequent breakfast and exercise and excess screen time, and in young children it was associated with consumption of sweetened beverages or juice. Unhealthy dietary behaviors, screen time, limited exercise, and sleep were more prevalent in older children and in selected black, Hispanic, and Asian subgroups, where consumption of sweetened beverages or juice was especially high. Overall, obesity severity and obesogenic behaviors increased with age and varied by gender and race/ethnicity. We identified several key prevalent modifiable behaviors that can be targeted by healthcare professionals to reduce obesity when counseling children with obesity and their parents. PMID:26885385

    STUDY OBJECTIVES To describe patterns of outpatient antibacterial use among California Medicaid (Medi-Cal) fee-for-service system beneficiaries, and to investigate the influence of demographic factors—age, race-ethnicity, state county, and population density—on those patterns. DESIGN Retrospective analysis of administrative claims data. DATA SOURCE Medi-Cal fee-for-service system claims database. PATIENTS All outpatient Medi-Cal fee-for-service system beneficiaries enrolled between 2006 and 2011 who had at least one systemic antibacterial claim. MEASUREMENTS AND MAIN RESULTS Rates of antibacterial prescribing and the proportion of broad-spectrum antibacterial use were measured over the study period and among age, racial-ethnic and geographic (county) groups. Of the 10,018,066 systemic antibacterial claims selected for analysis, antibacterial prescribing rates decreased from 542 claims/1000 beneficiaries in 2006 to 461 claims/1000 beneficiaries in 2011 (r = –0.971, p = 0.0012; τ-b = –1.00, p = 0.009). Among age groups, children had the highest rate of use (605 claims/1000 beneficiaries, χ2 (2) = 320,000, p < 0.001); among racial-ethnic groups, Alaskan Natives and Native Americans had the highest rate of use (1086/1000 beneficiaries, χ2 (5) = 197,000, p < 0.001). Broad-spectrum antibacterial prescribing increased from 28.1% (95% confidence interval [CI] 28.1–28.2%) to 32.7% (95% CI 32.6–32.8%) over the study period. Senior age groups and Caucasians received the highest proportions of broad-spectrum agents (53.4% [95% CI 52.5–54.3%] and 36.6% [95% CI 36.6–36.7%], respectively). Population density was inversely related to both overall antibacterial use (ρ = –0.432, p = 0.0018) and broad-spectrum antibacterial prescribing (ρ = –0.359, p < 0.001). The rate of prescribing decreased over the study period for all antibacterial classes with the exception of macrolides and sulfonamides. Amoxicillin was the most frequently prescribed agent.

    The objectives of this study were to examine the outcomes of late stage breast cancer diagnosis, receiving first course treatment, and breast cancer-related death by race, age, and rural/urban residence in Georgia. The authors used cross-sectional and follow-up data (1992-2007) for Atlanta and Rural Georgia cancer registries that are part of the National Cancer Institute's Surveillance, Epidemiology, and End Results Program (N = 23,500 incident breast cancer cases in non-Hispanic whites or non-Hispanic African Americans). Multilevel modeling and Cox proportional hazard models revealed that compared to whites, African American women had significantly increased odds of late stage diagnosis (odds ratio [OR] = 2.08, p = 0.0001) and unknown tumor stage (OR = 1.27, p = 0.0001), decreased odds of receiving radiation (OR = 0.93, p = 0.041) or surgery (OR = 0.50, p = 0.0001), and increased risk of death following breast cancer diagnosis (hazard rate ratio [HR] = 1.50, p = 0.0001). Increased age was significantly associated with the odds of late/unknown stage at diagnosis, worse treatment, and survival. Women residing in rural areas had significantly decreased odds of receiving radiation and surgery with radiation (OR = 0.59, p = 0.0001), and for receiving breast-conserving surgery compared to mastectomy (OR = 0.73, p = 0.005). Factors affecting each level of the breast cancer continuum are distinct and should be examined separately. Efforts are needed to alleviate disparities in breast cancer outcomes in hard-to-reach populations. PMID:22591230

    Introduction Cannabis is one of the most widely used psychoactive substances in the United States (U.S.). Perceived risk of use is associated with substance use; the recent debate surrounding medicalization and legalization of cannabis in the U.S. has the potential to impact perceived risk of use. Recent estimates are needed to assess temporal changes in, and identify correlates of, perceived risk of cannabis use. Methods Utilizing data from the 2002–2012 survey years of the National Survey on Drug Use and Health, chi-squared statistics and logistic regression were used to describe temporal changes in perceived risk of regular cannabis use (i.e., once or twice a week), to explore correlates of perceived risk, and to report frequency of cannabis use. Results Between 2002–2012, perceived great risk of regular cannabis use varied significantly overall (p<0.001). The prevalence of past year non-daily (p<0.001) and daily use varied significantly during this time (p<0.001). Controlling for survey year and other confounders, characteristics associated with increased odds of perceived great risk of regular cannabis use included: female sex; Non-White race/ethnicity; age 50+; and family income of $20,000–49,999. Characteristics associated with decreased odds of perceived great risk included: ages 12–17 and 18–25; high school education or greater; total family income of $75,000+; past year non-daily and daily cannabis use; and survey years 2008–2012. Conclusions Findings characterize trends of perceived risk of regular cannabis use, and past year non-daily and daily cannabis use. Longitudinal studies of the influence of legal status of cannabis at the state-level are needed. PMID:25735467

    Long chain polyunsaturated fatty acids (LCPUFA) are added to infant formula but their effect on long-term growth of children is under studied. We evaluated the effects of feeding LCPUFA-supplemented formula (n = 54) compared to control formula (n = 15) throughout infancy on growth from birth-6 years. Growth was described using separate models developed with the MIXED procedure of SAS(®) that included maternal smoking history and gender. Compared to children fed control formula, children who consumed LCPUFA supplemented formula had higher length-/stature-/and weight-for-age percentiles but not body mass index (BMI) percentile from birth to 6 years. Maternal smoking predicted lower stature (2-6 years), higher weight-for-length (birth-18 months) and BMI percentile (2-6 years) independent of LCPUFA effects. Gender interacted with the effect of LCPUFA on stature, and the relationship between smoking and BMI, with a larger effect for boys. Energy intake did not explain growth differences. A relatively small control sample is a limitation. PMID:25936840

  20. Race concepts in medicine.

    2013-02-01

    Confusions about the place of race in medicine result in part from a failure to recognize the plurality of race concepts. Recognition that the ordinary concept of race is not identical to the racialist concept of race makes it possible to ask whether there might be a legitimate place for the deployment of concepts of race in medical contexts. Two technical race concepts are considered. The concept of social race is the concept of a social group that is taken to be a racialist race. It is apt for use in examining and addressing the medical effects of discrimination. The populationist concept of race represents race as a kind of biological population. It makes it possible to frame the question whether biological race is a factor in disease susceptibility and drug responsiveness. It is apt for use in determining whether biological race is a medically significant category. PMID:23300217

    This paper uses a regression discontinuity design to estimate the impact of the minimum legal drinking age laws on alcohol consumption, smoking, and marijuana use among young adults. Using data from the National Longitudinal Survey of Youth (1997 Cohort), we find that granting legal access to alcohol at age 21 leads to an increase in several measures of alcohol consumption, including an up to a 13 percentage point increase in the probability of drinking. Furthermore, this effect is robust under several different parametric and non-parametric models. We also find some evidence that the discrete jump in alcohol consumption at age 21 has negative spillover effects on marijuana use but does not affect the smoking habits of young adults. Our results indicate that although the change in alcohol consumption habits of young adults following their 21st birthday is less severe than previously known, policies that are designed to reduce drinking among young adults may have desirable impacts and can create public health benefits.

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

    Objectives Since sex hormone markers are metabolically linked, examining sex steroid hormones singly may account for inconsistent findings by age, race/ethnicity and body mass index (BMI) across studies. First, these markers were statistically combined into profiles to account for the metabolic relationship between markers. Then, the relationships between sex steroid hormone profiles and age, race/ethnicity and BMI were explored in multinomial logistic regression models. Design Cross-sectional survey. Setting The US Third National Health and Nutrition Examination Survey (NHANES III). Participants 1538 Men, >17 years. Primary outcome measure Sex hormone profiles. Results Cluster analysis was used to identify four statistically determined profiles with Blom-transformed T, E, sex hormone binding globulin (SHBG), and 3-α diol G. We used these four profiles with multinomial logistic regression models to examine differences by race/ethnicity, age and BMI. Mexican American men >50 years were associated with the profile that had lowest T, E and 3-α diol G levels compared to other profiles (p<0.05). Non-Hispanic Black, overweight (25–29.9 kg/m2) and obese (>30 kg/m2) men were most likely to be associated with the cluster with the lowest SHBG (p<0.05). Conclusion The associations of sex steroid hormone profiles by race/ethnicity are novel, while the findings by age and BMI groups are largely consistent with observations from single hormone studies. Future studies should validate these hormone profile groups and investigate these profiles in relation to chronic diseases and certain cancers. PMID:23043125

    A 53-year-old woman with a history of dyslipidemia presented with medium-grade proteinuria and several years of progressive renal dysfunction. Renal biopsy showed diffuse and global Kimmelstiel-Wilson nodule like nodular mesangial sclerosis, but she had no history of diabetes mellitus, no diabetic retinopathy and normal oral glucose tolerance. Congo red staining was negative, and immunofluorescence staining showed no immunoglobulin deposition including kappa or lambda light chains. Electron microscopy showed no electron dense deposits or organized deposits. Thus, we diagnosed idiopathic nodular glomerulosclerosis (ING). ING is a recently established clinicopathologic disease entity linked to longstanding cigarette smoking and hypertension. Obesity is also listed as a contributing factor. However, none of these factors was documented in this case. This is a valuable case of ING that suggests the existence of as-yet unknown causative factors of ING other than smoking, hypertention or obesity. PMID:26019825

    Background Alcohol consumption during pregnancy, a known teratogen often associated with drug use and smoking, is a well-known public health concern. Aim This study provides prevalence data for alcohol, smoking, and illicit drug use before, during, and after pregnancy among Inuit. Factors associated with alcohol use are also identified. Methods 248 Inuit women from Arctic Quebec were interviewed at mid-pregnancy, and at 1 and 11 months postpartum to provide descriptive data on smoking, alcohol, and drug use during pregnancy, and the year before and after pregnancy. Sociodemographic and family characteristics potentially associated with alcohol use were documented. Results 92% of the women reported smoking and 61% reported drinking during pregnancy. Episodes of binging during pregnancy were reported by 62% of the alcohol users, which corresponds to 38% of pregnant women. 36% of the participants reported using marijuana during pregnancy. Alcohol use and binge drinking during pregnancy were more likely to be reported by women who lived in less crowded houses, had a better knowledge of a second language, drank alcohol more often and in larger amounts prior to pregnancy, and used illicit drugs. Binge drinkers were more likely to be single women and to have had fewer previous pregnancies. Postpartum distress and violence were more likely to be experienced by women who used alcohol during pregnancy. Binge drinking during pregnancy was best predicted by drinking habits before pregnancy, maternal symptoms of depression, the use of illicit drugs during pregnancy and the number of young children living with the mother. Conclusions These results confirm that alcohol is a major risk factor to maternal and child health in this population, underscoring the need for culturally relevant and effective prevention programs.

    Objectives To determine the prevalence of cigarette smoking cessation and examine the association between cessation and various factors among workers in a nationally representative sample of US adults. Methods Data were derived from the 2010 National Health Interview Survey. Prevalence rates were calculated for interest in quitting smoking, making an attempt to quit smoking, and successful smoking cessation (defined as smokers who had quit for 6–12 months). Logistic regression analyses were used to identify factors associated with cessation after adjustment for demographic characteristics (age group, race/ethnicity, educational level and marital status). Results Data were available for 17 524 adults who were employed in the 12 months prior to interview. The prevalence of quit interest, quit attempt and recent cessation was 65.2%, 53.8% and 6.8%, respectively. Quit interest was less likely among workers with long work hours, but more likely among workers with job insecurity, or frequent workplace skin and/or respiratory exposures. Quit attempt was more likely among workers with a hostile work environment but less likely among workers living in a home that permitted smoking or who smoked ≥11 cigarettes/day. Recent smoking cessation was less likely among workers with frequent exposure to others smoking at work or living in a home that permitted smoking, but more likely among workers with health insurance. Conclusions Factors associated with cessation interest or attempt differed from those associated with successful cessation. Cessation success might be improved by reducing exposure to others smoking at work and home, and by improving access to health insurance. PMID:24497440

    The objectives of this study are to estimate smoke alarm coverage and adherence with national guidelines in low- to mid-value owner-occupied residences, and to identify resident demographic, behavioral, and building characteristics and other fire and burn safety practices associated with smoke alarm utilization. Baseline visits were conducted with 779 households in King County, Washington, for a randomized trial of smoke alarm functionality. Presence, functionality, features, and location of pre-existing smoke alarms were ascertained by staff observation and testing. Household and building descriptors were collected using questionnaires. Households were classified by presence of smoke alarms, functional alarms, and functional and properly mounted alarms placed in hallways and on each floor but not in recommended avoidance locations. Smoke alarms were present in 89%, and functional units in 78%, of households. Only 6-38% met all assessed functionality and placement recommendations. Homes frequently lacked alarms in any bedrooms or on each floor. Building age, but not renovation status, was associated with all dimensions of smoke alarm coverage; post-1980 constructions were 1.7 times more likely to comply with placement recommendations than were pre-1941 homes (95% CI: 1.1-2.6). Respondent education and race/ethnicity, children <5 years, residency duration, number of floors, wood stoves and fireplaces, number of smoke alarms, recency of smoke alarm testing, carbon monoxide monitors, and fire ladders displayed varying relationships with alarm presence, functionality, and placement. Strategies for maintaining smoke alarms in functional condition and improving compliance with placement recommendations are necessary to achieve universal coverage, and will benefit the majority of households.

    Efforts toward controlling secondhand smoke in public places have been made throughout China. However, in contrast to the western world, significant challenges remain for effectively implementing smoke-free regulations. This study explores individual and regional factors which influence smoking in smoke-free public places. Participants included 16 866 urban residents, who were identified through multi-stage sampling conducted in 21 Chinese cities. The reported smoking prevalence in smoke-free public places was 41.2%. Of those who smoked in smoke-free public places, 45.9% had been advised to stop smoking. Participants stated that no-smoking warnings/signs with 'please' in the statement had a better likelihood of gaining compliance and preventing smoking in public spaces. Multilevel logistic regression analysis showed that ethnicity, education, occupation, type of smoking, age of smoking initiation, smoking situation, stress, household smoking restrictions and city population were all associated with smoking in smoke-free public places. Interestingly local smoke-free regulations were not associated with smoking in public places. The findings underscore that efforts to restrict smoking in public places in China should emphasize strong enforcement, while simultaneously raising public awareness of the perils of second hand smoke.

    Background An association between lower IQ of parents, measured early in life, and smoking among their offspring has been reported. The extent to which other background factors account for this association is unknown. Methods Data on IQ, smoking, mental health, social class, parental divorce and social problems in a cohort of men born during 1949–1951 and conscripted for military service in 1969 were linked to smoking data on 682 offspring interviewed in the Swedish Surveys of Living Conditions 1984–2009. Results In an age-adjusted model, a one-step decrease on a stanine scale was associated with an OR of 1.19 (95% CI 1.04 to 1.35) for offspring smoking. Adjusting for father's socioeconomic background and smoking, mental illness and social problems in youth only marginally lowered the OR's. Conclusions Lower IQ among fathers measured at ages 18–20 years was associated with smoking in their offspring. The association was not explained by father's social class in childhood or a higher prevalence of mental illness, social problems or smoking measured among the fathers in their late adolescence.

    Background Tobacco smoking (TS) and illicit drug use (IDU) are of public health concerns especially in developing countries, including Bangladesh. This paper aims to (i) identify the determinants of TS and IDU, and (ii) examine the association of TS with IDU among young slum dwellers in Bangladesh. Methodology/Principal Findings Data on a total of 1,576 young slum dwellers aged 15–24 years were extracted for analysis from the 2006 Urban Health Survey (UHS), which covered a nationally representative sample of 13,819 adult men aged 15–59 years from slums, non-slums and district municipalities of six administrative regions in Bangladesh. Methods used include frequency run, Chi-square test of association and multivariable logistic regression. The overall prevalence of TS in the target group was 42.3%, of which 41.4% smoked cigarettes and 3.1% smoked bidis. The regression model for TS showed that age, marital status, education, duration of living in slums, and those with sexually transmitted infections were significantly (p<0.001 to p<0.05) associated with TS. The overall prevalence of IDU was 9.1%, dominated by those who had drug injections (3.2%), and smoked ganja (2.8%) and tari (1.6%). In the regression model for IDU, the significant (p<0.01 to p<0.10) predictors were education, duration of living in slums, and whether infected by sexually transmitted diseases. The multivariable logistic regression (controlling for other variables) revealed significantly (p<0.001) higher likelihood of IDU (OR = 9.59, 95% CI = 5.81–15.82) among users of any form of TS. The likelihood of IDU increased significantly (p<0.001) with increased use of cigarettes. Conclusions/Significance Certain groups of youth are more vulnerable to TS and IDU. Therefore, tobacco and drug control efforts should target these groups to reduce the consequences of risky lifestyles through information, education and communication (IEC) programs. PMID:23935885

    Global personalized medicine demands the characterization of person-to-person and between-population differences in drug pharmacokinetics and pharmacodynamics. CYP2C9 pharmacokinetic pathway is subject to modulation by both genetic and environmental factors. CYP2C9 genotype-based dose recommendations (e.g., for warfarin) is advocated. However, the overall contribution of genotype for variation in enzyme activity may differ between populations. We evaluated the importance of ethnicity, genotype, smoking, body weight, age, and sex for CYP2C9 enzyme activity. CYP2C9 genotype and phenotype was determined in 148 Swedes and 146 Koreans using losartan as a probe. CYP2C9 enzyme activity was assessed using urinary losartan/metabolite E-3174 ratio. The frequency of CYP2C9 defective variant alleles (*2 and *3) was significantly higher in Swedes (10.8% and 12.5%) than in Koreans (0% and 5.8%). In matched genotypes, CYP2C9 enzyme activity was significantly lower in Swedes compared to Koreans (p<0.0001). In a univariate analysis, age, weight, ethnicity, genotype, and smoking were significant predictors of CYP2C9 phenotype. A stepwise multivariate analysis indicated ethnicity, genotype, and smoking remained as significant predictors of CYP2C9 enzyme activity, accounting for 50% of the total variance. In both study populations, CYP2C9 genotype was a significant predictor of CYP2C9 enzyme activity, but its contribution in explaining the total variance was lower in Koreans (26.6%) than Swedes (40%). In conclusion, we report significantly lower CYP2C9 enzyme activity in Swedes compared to Koreans, partly but not exclusively due to CYP2C9 pharmacogenetic variations. Ethnicity and environment factors need to be considered together with genotype for population-specific dose optimization and global personalized medicine. PMID:25977991

    Introduction Sarcoidosis is a multi-organ system granulomatous disease of unknown origin with an incidence of 1–40/100,000. Though pulmonary manifestations are predominant, ocular sarcoidosis (OS) affects 25–50% of patients with sarcoidosis and can lead to blindness. Methods A retrospective, single-center chart review of sarcoidosis cases investigated variables associated with the development of OS. Inclusion criteria were biopsy-proven sarcoidosis, disease duration greater than 1 year, documented smoking status on chart review and documentation of sarcoid-related eye disease. Multivariate analysis identified independent risk factors for OS. Results Of 269 charts reviewed, 109 patients met inclusion criteria. The OS group had a significantly higher proportion of smokers (71.4%) than without OS (42.0%, p=0.027) with no difference (p=0.61) in median number of pack years. Male sex was significantly higher in the OS group (57.1% versus 26.1%, p=0.009). Median duration of sarcoidosis was higher in the OS group (10 versus 4 years, p=0.031). Multivariate regression identified tobacco exposure (OR=5.25, p=0.007, 95% CI 1.58–17.41), male sex (OR=7.48, p=0.002, 95% CI 2.15–26.01), and age (OR=1.114, p=0.002, 95% CI 1.04–1.19) as concomitant risk factors for the development of OS. Conclusion To date, there are few dedicated investigations of risk factors for OS, especially smoking. This investigation identified male sex, age, and tobacco exposure as independent risk factors for OS. Though disease duration did not withstand regression analysis in this moderately sized group, age at chart review suggests screening for OS should not remit but rather intensify in aging patients with sarcoidosis.

    Shisha café patrons in Cairo, Egypt were interviewed to assess their knowledge, attitudes and practices regarding smoking and health. The median age of initiation of Shisha smoking is 20 years. Shisha smokers know about the hazards of smoking and believe that Shisha smoking is less dangerous than cigarette smoking. Over half the Shisha smokers have tried to quit in the past year. The younger adults who smoke Shisha also tend to smoke more often with friends, smoke cigarettes in addition to Shisha and prefer fruit flavored tobacco as compared to tobacco mixed with molasses favored by Shisha smokers who are older. Heavy Shisha smoking was not related to age. PMID:15119471

    Background Exposure to smoking in movies has been linked to adolescent smoking uptake. However, beyond linking amount of exposure to smoking in movies with adolescent smoking, whether the way that smoking is portrayed in movies matters for influencing adolescent smoking has not been investigated. This study experimentally examined how motivation for smoking depicted in movies affects self-reported future smoking risk (a composite measure with items that assess smoking refusal self-efficacy and smoking intentions) among early adolescents. Methods A randomized laboratory experiment was used. Adolescents were exposed to movie scenes depicting one of three movie smoking motives: social smoking motive (characters smoked to facilitate social interaction); relaxation smoking motive (characters smoked to relax); or no smoking motive (characters smoked with no apparent motive, i.e., in neutral contexts and/or with neutral affect). Responses to these movie scenes were contrasted (within subjects) to participants’ responses to control movie scenes in which no smoking was present; these control scenes matched to the smoking scenes with the same characters in similar situations but where no smoking was present. A total of 358 adolescents, aged 11–14 years, participated. Results Compared with participants exposed to movie scenes depicting characters smoking with no clear motive, adolescents exposed to movie scenes depicting characters smoking for social motives and adolescents exposed to movie scenes depicting characters smoking for relaxation motives had significantly greater chances of having increases in their future smoking risk. Conclusions Exposure to movies that portray smoking motives places adolescents at particular risk for future smoking. PMID:22074766

    Although studies in Western populations have shown that smokers have decreased dietary intakes of antioxidants and other health-related nutrients, this has not been established in oriental populations. This study aimed to identify differences in dietary and lifestyle characteristics between current, former, and never-smokers among middle-aged and older Chinese in Singapore. The subjects, 45-74 y old, were participants in the Singapore Chinese Health Study, a prospective cohort that enrolled 63,257 (27,959 men and 35,298 women) Chinese in Singapore between 1993 and 1998. Data on current dietary habits (using a validated, semiquantitative FFQ) and other lifestyle factors were collected through face-to-face interviews. Mean daily intakes of various nutrients were estimated using a food composition table that was specifically developed for this population. The current smoking rates were 36% in men and 6% in women; an additional 22% of men and 3% of women were former smokers. In both sexes, current smokers were less educated, had lower BMI, led a more sedentary lifestyle, and drank more alcohol and coffee than those who never smoked. Current smokers had dose-dependent decreases in the intakes of a wide range of antioxidants, vitamins, fiber, and calcium, but increases in the intakes of cholesterol and nitrosamines compared with people who never smoked. Former smokers had dietary intakes that either were similar to never-smokers or intermediate between current and never-smokers. Our results are consistent with findings among Western populations, and suggest that the unhealthy diet and lifestyle in smokers occur across diverse cultures. PMID:16177215

    The aim of this study was to estimate the effect of exposure to secondhand tobacco smoke on the incidence of lung adenocarcinoma in situ/minimally invasive adenocarcinoma (AIS/MIA). Data from seven case-control studies participating in the International Lung Cancer Consortium (ILCCO) were pooled, resulting in 625 cases of AIS/MIA and 7,403 controls, of whom 170 cases and 3,035 controls were never smokers. Unconditional logistic regression was used to estimate adjusted ORs (ORadj) and 95% confidence intervals (CI), controlling for age, sex, race, smoking status (ever/never), and pack-years of smoking. Study center was included in the models as a random-effects intercept term. Ever versus never exposure to secondhand tobacco smoke was positively associated with AIS/MIA incidence in all subjects (ORadj = 1.48; 95% CI, 1.14-1.93) and in never smokers (ORadj = 1.45; 95% CI, 1.00-2.12). There was, however, appreciable heterogeneity of ORadj across studies (P = 0.01), and the pooled estimates were largely influenced by one large study (40% of all cases and 30% of all controls). These findings provide weak evidence for an effect of secondhand tobacco smoke exposure on AIS/MIA incidence. Further studies are needed to assess the impact of secondhand tobacco smoke exposure using the newly recommended classification of subtypes of lung adenocarcinoma. PMID:26503035

    This study investigated the associations of youth cigarette smoking with tobacco outlet densities and proximity of tobacco outlets to youth homes and schools across different buffers in 45 midsized California communities. The sample comprised 832 youths who were surveyed about their smoking behaviors. Inclusion criteria included both home and school addresses within city boundaries. Observations in the 45 cities were conducted to document addresses of tobacco outlets. City- and buffer-level demographics were obtained and negative binomial regression analyses with cluster robust standard errors were conducted. All models were adjusted for youth gender, age, and race. Greater densities of tobacco outlets within both a 0.75 and 1-mile buffer of youth homes were associated with higher smoking frequency. Neither tobacco outlet densities around schools nor distance to the nearest tobacco outlet from home or school were associated with youths past-30-day smoking frequency. Lower population density and percent of African Americans in areas around homes and lower percent of unemployed in areas around schools were associated with greater smoking frequency. Results of this study suggest that restricting outlet density within at least 1-mile surrounding residential areas will help to reduce youth smoking. PMID:24254336

    IMPORTANCE Electronic cigarettes (e-cigarettes) may help smokers reduce the use of traditional combustible cigarettes. However, adolescents and young adults who have never smoked traditional cigarettes are now using e-cigarettes, and these individuals may be at risk for subsequent progression to traditional cigarette smoking. OBJECTIVE To determine whether baseline use of e-cigarettes among nonsmoking and nonsusceptible adolescents and young adults is associated with subsequent progression along an established trajectory to traditional cigarette smoking. DESIGN, SETTING, AND PARTICIPANTS In this longitudinal cohort study, a national US sample of 694 participants aged 16 to 26 years who were never cigarette smokers and were attitudinally nonsusceptible to smoking cigarettes completed baseline surveys from October 1, 2012, to May 1, 2014, regarding smoking in 2012–2013. They were reassessed 1 year later. Analysis was conducted from July 1, 2014, to March 1, 2015. Multinomial logistic regression was used to assess the independent association between baseline e-cigarette use and cigarette smoking, controlling for sex, age, race/ethnicity, maternal educational level, sensation-seeking tendency, parental cigarette smoking, and cigarette smoking among friends. Sensitivity analyses were performed, with varying approaches to missing data and recanting. EXPOSURES Use of e-cigarettes at baseline. MAIN OUTCOMES AND MEASURES Progression to cigarette smoking, defined using 3 specific states along a trajectory: nonsusceptible nonsmokers, susceptible nonsmokers, and smokers. Individuals who could not rule out smoking in the future were defined as susceptible. RESULTS Among the 694 respondents, 374 (53.9%) were female and 531 (76.5%) were non-Hispanic white. At baseline, 16 participants (2.3%) used e-cigarettes. Over the 1-year follow-up, 11 of 16 e-cigarette users and 128 of 678 of those who had not used e-cigarettes (18.9%) progressed toward cigarette smoking. In the primary

    Systemic lupus erythematosus (SLE), an autoimmune inflammatory disease, is associated with an increased prevalence of accelerated atherosclerosis and cardiovascular events. Metabolic syndrome (MetS) is a set of cardiovascular risk factors in SLE patients, which may lead to a proinflammatory condition and increased morbidity and mortality. The objective of this study was to evaluate the prevalence of MetS in a cohort of SLE patients versus healthy controls, and to analyze the association of clinical and demographic factors. SLE patients (n = 146) treated at a Northeast Brazilian university hospital were evaluated with regard to demographic, clinical, laboratory, and anthropometric parameters and compared to controls (n = 101). MetS was diagnosed according to the definition of 2005 NCEP/ATP III. The average age of SLE patients was 41.7 ± 12.5 years, and 91.8 % were female. MetS was significantly more prevalent in SLE patients (45.2 %) than in controls (32.7 %; p = 0.04). The MetS components such as hypertension, diabetes, and hypertriglyceridemia were significantly more prevalent in SLE. In the univariate analysis, MetS in SLE patients was associated with age, disease duration, Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index, smoking, menopause, nephritis, cyclophosphamide use, prednisone dose, and chloroquine use, which appeared to have a protective effect. In the logistic regression analysis, age, disease activity, nephritis, and smoking were statistically significant. The prevalence of MetS observed in our cohort of SLE patients from Northeastern Brazil is higher than controls. MetS components should be routinely investigated to minimize the occurrence of MetS and associated cardiovascular morbidity and mortality. PMID:26149124

    We describe a mumps outbreak in a highly-vaccinated population attending a party at a youth club. In a retrospective cohort study with 60 of approximately 100 participants responding, vaccination status was verified for 58/59 respondents, of whom 54 were vaccinated twice and four once. The attack rate was 22% (13 cases, all vaccinated), with smoking at the party (risk ratio (RR) 3.1; 95% confidence interval (CI): 1.6–6.0, p=0.001) and age ≥21 years (RR 4.7; 95% CI: 2.1–10.2, p<0.0001) as risk factors for disease in the binominal regression analysis. Mild upper respiratory illness was also highly prevalent in those who did not meet the mumps case definition (n=46) after the party, suggesting that mumps virus infection may cause mild disease in vaccinated individuals. Our investigation adds toevidence that crowded social events and smoking may facilitate spread of mumps virus among vaccinated populations, with waning immunity playing a role. The suggestion that mumps virus infection in vaccinated individuals may manifest as mild upper respiratory illness could have implications for transmission and warrants further investigation.

    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). PMID:27087182

    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.

    2 of the 5 health warnings that must now appear on American cigarette packs and cigarette advertising refer to some of the increased hazards smoking entails for the woman and her unborn child. Yet, the myriad reproductive risks associated with smoking are little known or considered by the general public--or even by physicians--when compared with the dangers of lung cancer, heart attacks and emphysema. In an attempt to remedy that deficit, 8 government agencies sponsored the 1st International Conference on Smoking and Reproductive Health, held October 15-17, 1985 in San Francisco. Speaker after expert speaker connected smoking during pregnancy with increased risks of low birth weight, miscarriage, infant mortality and morbidity--including poorer health of surviving children up to at least age 3--ectopic pregnancy, infertility, menstrual disorders, early menopause, osteoporosis, cervical cancer and dysplasia, cardiovascular disease and placental abnormalities. Similarly, the conference participants documented the association of smoking among men with lower sperm count and increased prevalence of abnormal sperm. The following measures were urged at the closing statements of the conference: 1) an increased effort to inform doctors and health professionals of these findings; 2) increasing the tax on cigarettes, so that smokers would pay for their own health costs; 3) decreasing or eliminating government subsidies for growing tobacco, while helping growers make the transition to nontobacco crops; 4) making smoking cessation programs more widely available; 5) prohibiting the sale of cigarettes through vending machines; and 6) banning all smoking in the workplace.

    Background Exposure to smoking imagery in films is consistently associated with smoking behavior and its psychological antecedents among adolescents in high-income countries, but its association with adolescent smoking in middle-income countries is unknown. Methods In 2006, a cross-sectional sample of 3876 Mexican adolescents in secondary school was surveyed on smoking behavior, smoking risk factors, and exposure to 42 popular films that contained smoking. Participants were classified into quartiles of exposure to smoking imagery across all films they reported having seen. Models were estimated to determine associations among quartiles of film-smoking exposure, smoking behavior, and the psychological antecedents of smoking, adjusting for age, gender, sensation seeking, self-esteem, parental smoking, sibling smoking, best-friend smoking, having a bedroom TV, and private versus public school attendance. Analyses were conducted in 2007. Results Adolescents were exposed to an average of 51.7 (SE=1.3) minutes of smoking in the films they viewed. Crude and adjusted ORs indicated positive associations between quartiles of film-smoking exposure and both current smoking (AOR4v1=3.13; p<0.0001) and having ever smoked (AOR4v1=2.42; p<0.0001). Data from never-smokers (n=2098) were analyzed to determine associations between film-smoking exposure and psychological antecedents of smoking uptake. Crude and adjusted coefficients indicated significant, positive associations between exposure and susceptibility to smoking (AOR4v1=1.66; p<0.05); favorable attitudes toward smoking (Adjusted B4v1=0.44; p<0.0001); and perceived peer prevalence of smoking (Adjusted B4v1=0.26; p<0.0001). Conclusions Exposure to smoking in films appears associated with smoking among Mexican adolescents. Policies could aim to decrease youth exposure to smoking in nationally and internationally distributed films. PMID:18617078

    We studied determinants of cadmium status and kidney function in nonsmoking men and women living on farms in southern Sweden. Median blood Cd (BCd) was 1.8 nmol/L (range, 0.38-18) and median urinary Cd (UCd) was 0.23 nmol/mmol creatinine (range, 0.065-0.99). The intake of Cd per kilogram body weight did not significantly differ between sexes and did not correlate with BCd or UCd, which may be explained by a low and varying bioavailibility of Cd from food items. However, when a subgroup of the study population, couples of never-smoking men and women, were compared, a lower intake per kilogram body weight was found in the women, but the women had a 1.8 times higher BCd and a 1.4 times higher UCd. The higher female BCd and UCd may be explained by higher absorption due to low iron status. BCd and UCd both increased with age and were higher in the ex-smokers, who had stopped smoking more than 5 years before the study, compared to never-smokers. The contribution of locally produced food to the total Cd intake was relatively low and varied. Males living in areas with low soil Cd had lower UCd than the others. However, Cd levels in kidneys from pigs, fed locally produced cereals, did not predict BCd or UCd in humans at the same farms. The kidney function parameter ss2-microglobulin-creatinine clearance was related to UCd, whereas urinary protein-HC, N-acetyl-ss-glucoseaminidase or albumin-creatinine clearance was not when age was accounted for. Hence, even at the low exposure levels in this study population, there was an indication of effect on biochemical markers of renal function. PMID:12460796

    Introduction: Smokers’ health-related outcome expectancies are associated with a number of important constructs in smoking research, yet there are no measures currently available that focus exclusively on this domain. This paper describes the development and evaluation of item banks for assessing the health expectancies of smoking. Methods: Using data from a sample of daily (N = 4,201) and nondaily (N = 1,183) smokers, we conducted a series of item factor analyses, item response theory analyses, and differential item functioning analyses (according to gender, age, and race/ethnicity) to arrive at a unidimensional set of health expectancies items for daily and nondaily smokers. We also evaluated the performance of short forms (SFs) and computer adaptive tests (CATs) to efficiently assess health expectancies. Results: A total of 24 items were included in the Health Expectancies item banks; 13 items are common across daily and nondaily smokers, 6 are unique to daily, and 5 are unique to nondaily. For both daily and nondaily smokers, the Health Expectancies item banks are unidimensional, reliable (reliability = 0.95 and 0.96, respectively), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.87). Results from simulated CATs showed that health expectancies can be assessed with good precision with an average of 5–6 items adaptively selected from the item banks. Conclusions: Health expectancies of smoking can be assessed on the basis of these item banks via SFs, CATs, or through a tailored set of items selected for a specific research purpose. PMID:25118229

    Smoking has been determined as a cause of chronic obstructive pulmonary disease (COPD) in most patients. Smoking cessation should be stressed above everything else for COPD patients under all conditions. A smoking habit is determined not as a preference but as a dependency on tobacco; therefore, smoking cessation is difficult solely based on one's motivation. Smoking cessation therapy is employed with cessation aids. Now, we can use nicotine-containing gum, patches, and the nicotine-receptor partial agonist varenicline. First, nicotine from tobacco is replaced with a nicotin patch, or a nicotine-free condition is induced by varenicline. Subsequently, the drugs are gradually reduced. In Japan, smoking cessation therapy is covered by public health insurance as definite requirements. PMID:22073582

    Young infants are known to prefer own-race faces to other race faces and recognize own-race faces better than other-race faces. However, it is entirely unclear as to whether infants also attend to different parts of own- and other-race faces differently, which may provide an important clue as to how and why the own-race face recognition advantage emerges so early. The present study used eye tracking methodology to investigate whether 6- to 10-month-old Caucasian infants (N = 37) have differential scanning patterns for dynamically displayed own- and other-race faces. We found that even though infants spent a similar amount of time looking at own- and other-race faces, with increased age, infants increasingly looked longer at the eyes of own-race faces and less at the mouths of own-race faces. These findings suggest experience-based tuning of the infant's face processing system to optimally process own-race faces that are different in physiognomy from other-race faces. In addition, the present results, taken together with recent own- and other-race eye tracking findings with infants and adults, provide strong support for an enculturation hypothesis that East Asians and Westerners may be socialized to scan faces differently due to each culture's conventions regarding mutual gaze during interpersonal communication.

    The performance of two Olympic race walkers was studied during free-speed, fast, and race walking. Measurements of the stride and temporal components of gait, as well as the simultaneous displacement patterns of the body segments, and the electromyographic activity of muscles of the trunk and upper and lower limbs were recorded during the three walking speeds. During the testing, the race walkers achieved an average speed of 12.5 km/hr as compared to the 8.7 km/hr average speed achieved by normal men of the same age during fast walking. Race walking was characterized by an increase in cadence and stride length beyond that of normal controls (in a prior study) during fast walking, with stride lengths averaging 125% of stature during race walking, and 115% during normal fast walking. In the two race walkers the amplitudes of most of the movement patterns of the trunk and upper and lower limbs were exaggerated during race walking as compared to normal controls' fast walking. Several mechanisms were used by the race walkers to minimize the vertical excursion of the center of gravity of the body during race walking. All of the muscles monitored in the race walkers showed an increase in the amplitude of electromyographic activity during race walking as compared to fast walking; duration of muscle activity was also usually increased during race walking. Several suggestions for prevention of injuries associated with race walking are made. PMID:6846684

    Onscreen Smoking Is a Form of Tobacco Marketing Tobacco advertising has been prohibited in New Zealand since 1990, and the government has set a goal of becoming a smokefree nation by 2025. However, tobacco marketing persists indirectly through smoking in motion pictures, and there is strong evidence that exposure to onscreen smoking causes young people to start smoking. We investigated the relationship between exposure to smoking in movies and youth smoking initiation among New Zealand young adults. Data from an online survey of 419 smokers and non-smokers aged 18 to 25 were used to estimate respondents’ exposure to smoking occurrences in 50 randomly-selected movies from the 423 US top box office movies released between 2008 and 2012. Analyses involved calculating movie smoking exposure (MSE) for each respondent, using logistic regression to analyse the relationship between MSE and current smoking behaviour, and estimating the attributable fraction due to smoking in movies. Effect of Smoking in Movies on New Zealand Youth Exposure to smoking occurrences in movies was associated with current smoking status. After allowing for the influence of family, friends and co-workers, age and rebelliousness, respondents’ likelihood of smoking increased by 11% for every 100-incident increase in exposure to smoking incidents, (aOR1.11; p< .05). The estimated attributable fraction due to smoking in movies was 54%; this risk could be substantially reduced by eliminating smoking from movies currently rated as appropriate for youth. We conclude that exposure to smoking in movies remains a potent risk factor associated with smoking among young adults, even in a progressive tobacco control setting such as New Zealand. Harmonising the age of legal tobacco purchase (18) with the age at which it is legal to view smoking in movies would support New Zealand’s smokefree 2025 goal. PMID:26960189

    High rates of tobacco use is still observed in working-age population in Poland. The present level of the state tobacco control has been achieved through adopting legal regulations and population-based interventions. In Poland a sufficient contribution of health professionals to the diagnosis of the tobacco-addition syndrome (TAS) and the application of the 5A's (ask, advice, assess, assist, arrange follow-up) brief intervention, has not been confirmed by explicit research results. Systemic solutions of the health care system of the professional control, specialist health care, health professional trainings and reference centres have not as yet been elaborated. The tools for diagnosing tobacco dependence and motivation to quit smoking, developed over 30 years ago and recommended by experts to be used in clinical and research practice, have not met the current addiction criteria. In this paper other tools than those previously recommended - tests developed in the first decade of the 21st century (including Cigarette Dependence Scale and Nicotine Dependence Syndrome Scale), reflecting modern concepts of nicotine dependence are presented. In the literature on the readiness/motivation to change health behaviors, a new approach dominates. The motivational interviewing (MI) by Miller and Rollnick concentrates on a smoking person and his or her internal motivation. Motivational interviewing is recommended by the World Health Organization as a 5R's (relevance, risks, rewards, roadblocks, repetition) brief motivational advice, addressed to tobacco users who are unwilling to make a quit attempt. In Poland new research studies on the implementation of new diagnostic tools and updating of binding guidelines should be undertaken, to strengthen primary health care in treating tobacco dependence, and to incorporate MI and 5R's into trainings in TAS diagnosing and treating addressed to health professionals.

    Biochemical indicators of water-soluble vitamin (WSV) status were measured in a nationally representative sample of the U.S. population in NHANES 2003-2006. To examine whether demographic differentials in nutritional status were related to and confounded by certain variables, we assessed the association of sociodemographic (age, sex, race-ethnicity, education, income) and lifestyle (dietary supplement use, smoking, alcohol consumption, BMI, physical activity) variables with biomarkers of WSV status in adults (aged ≥ 20 y): serum and RBC folate, serum pyridoxal-5'-phosphate (PLP), serum 4-pyridoxic acid, serum total cobalamin (vitamin B-12), plasma total homocysteine (tHcy), plasma methylmalonic acid (MMA), and serum ascorbic acid. Age (except for PLP) and smoking (except for MMA) were generally the strongest significant correlates of these biomarkers (|r| ≤ 0.43) and together with supplement use explained more of the variability compared with the other covariates in bivariate analysis. In multiple regression models, sociodemographic and lifestyle variables together explained from 7 (vitamin B-12) to 29% (tHcy) of the biomarker variability. We observed significant associations for most biomarkers (≥ 6 of 8) with age, sex, race-ethnicity, supplement use, smoking, and BMI and for some biomarkers with PIR (5 of 8), education (1 of 8), alcohol consumption (4 of 8), and physical activity (5 of 8). We noted large estimated percentage changes in biomarker concentrations between race-ethnic groups (from -24 to 20%), between supplement users and nonusers (from -12 to 104%), and between smokers and nonsmokers (from -28 to 8%). In summary, age, sex, and race-ethnic differentials in biomarker concentrations remained significant after adjusting for sociodemographic and lifestyle variables. Supplement use and smoking were important correlates of biomarkers of WSV status. PMID:23576641

    Background Dementia severity can be modeled as the construct δ, representing the “cognitive correlates of functional status.” Objective We recently validated a model for estimating δ in the National Alzheimer’s Coordinating Center’s Uniform Data Set; however, δ’s association with neuropathology remains untested. Methods We used data from 727 decedents evaluated at Alzheimer’s Disease (AD) Centers nationwide. Participants spoke English, had no genetic abnormalities, and were pathologically diagnosed with AD as a primary or contributing etiology. Clinical data from participants’ last visit prior to death were used to estimate dementia severity (δ). Results A structural equation model using age, education, race, and apolipoprotein E (APOE) genotype (number of ε2 and ε4 alleles) as predictors and latent AD pathology and cerebrovascular disease (CVD) pathology as mediators fit the data well (RMSEA = 0.031; CFI = .957). AD pathology mediated the effects of age and APOE genotype on dementia severity. An older age at death and more ε2 alleles were associated with less AD pathology and, in turn, with less severe dementia. In contrast, more ε4 alleles were associated with more pathology and more severe dementia. Although age and race contributed to differences in CVD pathology, CVD pathology was not related to dementia severity in this sample of decedents with pathologically confirmed AD. Conclusions Using δ as an estimate of dementia severity fits well within a structural model in which AD pathology directly affects dementia severity and mediates the relationship between age and APOE genotype on dementia severity.

    To determine whether DNA methylation (DNA-M) of the leptin receptor genotype (LEPR/LEPROT) links gestational smoking and leptin serum levels and BMI later in life, we focused on female offspring, 18 years of age, from the Isle of Wight Birth Cohort (IOWBC). Leptin binds to the leptin receptor encoded by the LEPR/LEPROT genotype. Using general linear models, we tested a two-stage model. First, we investigated whether single nucleotide polymorphisms (SNPs) acting as methylation quantitative trait loci (methQTLs) depending on gestational smoking were related to differentially methylated cytosine-phosphate-guanine (CpG) sites. In stage 2, we tested whether the selected CpG sites, in interaction with other SNPs (modifiable genetic variants, modGV), are associated with serum leptin and BMI (stage 2). Children from the IOWBC were followed from birth to age 18. Information on gestational smoking was gathered upon delivery. SNPs tagging LEPR and LEPROT genes were genotyped. Data on LEPR/LEPROT DNA-M and leptin were obtained from blood samples drawn at age 18; to determine BMI, height and weight were ascertained. Blood samples were provided by 238 girls. Of the 21 CpG sites, interactions between gestational smoking and SNPs were detected for 16 CpGs. Methylation of seven of the 16 CpGs were, in interaction with modGVs, associated with leptin levels at age 18 years. Two CpGs survived a multiple testing penalty and were also associated with BMI. This two-stage model may explain why maternal smoking has a long-term effect on leptin levels and BMI in girls at age 18 years. PMID:23875062

    This report assesses smoking rates and support for indoor smoking bans among club-going young adults in New York City. Nearly half of the sample were smokers. Gay, lesbian, and bisexual young adults were more likely to smoke than were heterosexual participants. No differences in smoking rates were found between sexes or between Whites and non-Whites. Support for the smoking ban exists among young adults (68.6%). This is universal, as no differences in support for the ban were found by sex, race, or sexual identity. Smokers supported the ban (57.8%) less than nonsmokers did (77.3%). Yet, it remains notable that a majority support the smoking ban among smokers. PMID:19731187

    Background Patients are being encouraged to go online to obtain health information and interact with their health care systems. However, a 2014 survey found that less than 60% of American adults aged 65 and older use the Internet, with much lower usage among black and Latino seniors compared with non-Hispanic white seniors, and among older versus younger seniors. Objective Our aims were to (1) identify race/ethnic and age cohort disparities among seniors in use of the health plan’s patient portal, (2) determine whether race/ethnic and age cohort disparities exist in access to digital devices and preferences for using email- and Web-based modalities to interact with the health care system, (3) assess whether observed disparities in preferences and patient portal use are due simply to barriers to access and inability to use the Internet, and (4) learn whether older adults not currently using the health plan’s patient portal or website have a potential interest in doing so in the future and what kind of support might be best suited to help them. Methods We conducted two studies of seniors aged 65-79 years. First, we used administrative data about patient portal account status and utilization in 2013 for a large cohort of English-speaking non-Hispanic white (n=183,565), black (n=16,898), Latino (n=12,409), Filipino (n=11,896), and Chinese (n=6314) members of the Kaiser Permanente Northern California health plan. Second, we used data from a mailed survey conducted in 2013-2014 with a stratified random sample of this population (final sample: 849 non-Hispanic white, 567 black, 653 Latino, 219 Filipino, and 314 Chinese). These data were used to examine race/ethnic and age disparities in patient portal use and readiness and preferences for using digital communication for health-related purposes. Results Adults aged 70-74 and 75-79 were significantly less likely than 65-69 year olds to be registered to use the patient portal, and among those registered, to have used the

    This study extends the theoretical and empirical literature on the relationship between education and smoking by focusing on the life course links between experiences from adolescence and health outcomes in adulthood. Differences in smoking by completed education are apparent at ages 12-18, long before that education is acquired. I use characteristics from the teenage years, including social networks, future expectations, and school experiences measured before the start of smoking regularly to predict smoking in adulthood. Results show that school policies, peers, and youths' mortality expectations predict smoking in adulthood but that college aspirations and analytical skills do not. I also show that smoking status at age 16 predicts both completed education and adult smoking, controlling for an extensive set of covariates. Overall, educational inequalities in smoking are better understood as a bundling of advantageous statuses that develops in childhood, rather than the effect of education producing better health.

    Objective Our objective is to assess the effect of genetic and environmental factors on Crohn’s disease location. Design We identified 628 Crohn’s disease patients within the Washington University database (April 2005-February 2010) that had complete information on 31 Crohn’s disease associated genotypes and clinical information on disease location (L1-L4), smoking, gender, race and age at diagnosis. For statistical reasons, the three major NOD2 alleles (rs2066844, rs2066845, rs2066847) were grouped together. Logistic regression incorporating all of the genotypes and clinical covariates, including smoking, was carried out with stepwise variable selection and by best subset selection. Results Stepwise variable selection selected three major covariates, composite NOD2 genotype, smoking, and TNFSF15 genotype, which are also the three covariates selected by the best subset method. While NOD2 genotype and smoking are positively associated with ileal (L1 + L3) disease, TNFSF15 genotype is positively associated with isolated colonic (L2) disease. Limitations The ability to detect disease site associations in this single center study may be limited by the population size, low allelic frequency and/or low odds ratio of certain CD risk alleles. Conclusion These results indicate that NOD2 genotype, smoking status and TNFSF15 genotype should be included as co-variates in assessing the effect of genetic and environmental factors on Crohn’s disease site location.

    Objective To report prevalence and correlates of waterpipe tobacco smoking (WTS) use among U.S. adults. Methods Data were from the 2009–2010 National Adult Tobacco Survey, a nationally representative sample of U.S. adults. Estimates of WTS ever and current use were reported overall, and by sex, age, race/ethnicity, educational attainment, annual household income, sexual orientation, and cigarette smoking status. State-level prevalence rates of WTS ever were reported using choropleth thematic maps for the overall population and by sex. Results The national prevalence of WTS ever was 9.8% and 1.5% for current use. WTS ever was more prevalent among those who are male (13.4%), 18–24 years old (28.4%) compared to older adults, non-Hispanic White (9.8%) compared to non-Hispanic Black, with some college education (12.4%) compared to no high school diploma, and reporting sexual minority status (21.1%) compared to heterosexuals. States with highest prevalence included DC(17.3%), NV(15.8%), and CA(15.5%). Conclusion WTS is now common among young adults in the US and high in regions where cigarette smoking prevalence is lowest and smoke-free policies have a longer history. To reduce its use, WTS should be included in smoke-free regulations and state and federal regulators should consider policy development in other areas, including taxes, labeling, and distribution.

    People perceive and evaluate others on the basis of social categories, such as race, gender and age. Initial processing of targets in terms of visually salient social categories is often characterized as inevitable. In the current study, we investigated the influence of processing goals on the representation of race in the visual processing stream. Participants were assigned to one of two mixed-race teams and categorized faces according to their group membership or skin color. To assess neural representations of race, we employed multivariate pattern analysis to examined neural activity related to the presentation of Black and White faces. As predicted, patterns of neural activity within the early visual cortex and fusiform gyri (FG) could decode the race of face stimuli above chance and were moderated by processing goals. Race decoding in early visual cortex was above chance in both categorization tasks and below chance in a prefrontal control region. More importantly, race decoding was greater in the FG during the group membership vs skin color categorization task. The results suggest that, ironically, explicit racial categorization can diminish the representation of race in the FG. These findings suggest that representations of race are dynamic, reflecting current processing goals. PMID:23196632

    Human beings do not passively perceive important social features about others such as race and age in social interactions. Instead, it is proposed that humans might continuously generate predictions about these social features based on prior similar experiences. Pre-awareness of racial information conveyed by others' faces enables individuals to act in "culturally appropriate" ways, which is useful for interpersonal relations in different ethnicity groups. However, little is known about the effects of prediction on the perception for own-race and other-race faces. Here, we addressed this issue using high temporal resolution event-related potential techniques. In total, data from 24 participants (13 women and 11 men) were analyzed. It was found that the N170 amplitudes elicited by other-race faces, but not own-race faces, were significantly smaller in the predictable condition compared to the unpredictable condition, reflecting a switch to holistic processing of other-race faces when those faces were predictable. In this respect, top-down prediction about face race might contribute to the elimination of the other-race effect (one face recognition impairment). Furthermore, smaller P300 amplitudes were observed for the predictable than for unpredictable conditions, which suggested that the prediction of race reduced the neural responses of human brains.

    BACKGROUND The majority of recent, well-designed studies have shown that long-term cigarette smoking increases colorectal cancer risk, but older studies with shorter durations of exposure often found no association. This study aimed to examine colorectal cancer risk by smoking exposure using data collected in the late 1950s and early 1960s. METHODS This case-control study examined colorectal cancer risk by lifetime smoking history. There were 1,365 patients who visited Roswell Park Cancer Institute (RPCI) between 1957 and 1965 diagnosed with primary, incident colorectal cancers that were matched to 4,096 malignancy-free controls on gender and age. Odds ratios were calculated using separate logistic regression models for each smoking exposure, while controlling for other tobacco use, county of residence, race, age, gender, and body mass index (BMI). RESULTS The adjusted OR for individuals who reported their greatest level of smoking to be more than 1 pack/day was 0.87 (95% CI=0.67–1.15). Among those who smoked 42 or more years, the adjusted OR was 0.89 (95% CI=0.68–1.15) compared to those who never smoked. For individuals who smoked more than 45 pack-years, the OR was 0.92 (95% CI=0.72–1.19). The results did not differ significantly by gender, although men had considerably greater exposure compared to women. Results also did not differ by colorectal sub-site. CONCLUSION No association was found between long-term cigarette smoking and colorectal cancer risk. These results are in accord with studies that followed cohorts throughout the 1950s and 1960s. Methodological limitations, such as missing data on covariates and the higher incidence of smoking-related illness in a hospital setting, may have contributed to the null results found in this study. Prolonged population exposure to cigarettes and perhaps a changing product may explain why more recent studies have reported a positive association between smoking and colorectal cancer.

    The objective of the present study was to investigate smoking habits among 699 secondary school students, along with their attitudes toward smoking and their perceptions on the consequences of tobacco use in their health. Our results indicate that Greek adolescents begin to smoke mainly due to curiosity and for stress reasons. Furthermore, having friends who smoke is highly associated with smoking and intention for smoking. Likewise, paternal smoking seems to reinforce students' intention for smoking. On the contrary, parental disapproval of smoking leads to anti-smoking behavior. Adolescents' attitudes toward smoking are also related to a series of similar factors such as parental educational status, parental smoking, and parental disapproval of smoking, friends who smoke, and, finally, adolescents' age, smoking behavior, and intention for smoking. The impact of tobacco use in human health seems to be understood better by older students. All these factors must be taken into account for a successful implementation of an anti-smoking intervention program. PMID:18540285

  18. Menthol cigarettes and smoking initiation: a tobacco industry perspective

    PubMed Central

    2011-01-01

    Objectives To determine what the tobacco industry knew about menthol cigarettes and the initiation of smoking. Methods Based on Food and Drug Administration staff-supplied research questions we used a snowball sampling strategy to search the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) between February and April 2010. Of the approximately 11 million documents available in the LTDL, the iterative searches returned tens of thousands of results. Researchers reviewed 2634 documents and 128 were deemed relevant to one or more of the research questions. Results The documents show that menthol is added to cigarettes in part because it is known to be an attractive feature to inexperienced smokers who perceive menthol cigarettes as less harsh and easier to smoke and because of their availability from friends and family. Second, the tobacco industry found that some youths smoke menthols because they perceive them to be less harmful than non-menthol cigarettes. A key product design issue concerns whether to increase brand menthol levels to appeal to the taste preferences of long-term menthol smokers or keep menthol levels lower to appeal to inexperienced smokers. Marketing studies showed that the companies carefully researched the menthol segment of the market in order to recruit younger smokers to their brands. The industry tracked menthol cigarette usage by age, gender and race to inform product development and marketing decisions. Conclusions Menthol is a prominent design feature used by cigarette manufacturers to attract and retain new, younger smokers. PMID:21504927

    In this study, a wide range of volatile organic constituents of aged and diluted sidestream tobacco smoke (ADSS) were determined in a controlled atmosphere, where ADSS is the sole source of target compounds. The ADSS was generated in a 30 m 3 environmental test chamber using a variety of cigarettes, including the Kentucky 1R4F reference cigarette and eight commercial brands, and a total of 24 experimental runs were conducted. Target analytes were divided into three groups, i.e. vapor and particulate phase markers for environmental tobacco smoke (ETS), volatile organic compounds (VOC) including carbonyls, and polycyclic aromatic hydrocarbons (PAH). The VOC samples were collected on triple sorbent traps, and then analyzed by thermal desorption coupled with gas chromatography/mass spectrometry (GC/MS), while the carbonyl compounds were sampled on DNPH cartridges, being analyzed by HPLC. ETS particles in the chamber were collected by high volume sampling, and then used for the determination of PAHs by GC/MS. Among more than 30 target VOCs, acetaldehyde appeared to be the most abundant compound, followed by 2-methyl-1,3-butadiene, and formaldehyde. The results from the chamber study were further used to generate characterized ratios of selected VOCs to 3-ethenyl pyridine (3-EP), a vapor phase ETS marker. The ratios appeared to be in generally good agreement with published values in the literature. This suggests that the characteristic ratios may be useful for quantifying the impact of ETS on the VOC concentrations in 'real world' indoor environments, which are affected by a complex mixture of components from multiple sources. The yields of ETS markers from this study are all slightly lower than those estimated by other studies, while VOC yields are in reasonable agreement in many cases with values in the literature. Among 16 target PAHs, chrysene appeared to be most abundant, followed by benzo(a)anthracene (BaA) and benzo(a)pyrene (BaP). The average contents of BaP and

    Objective Our study examined the hypothesis that sexual minority specific stress and trauma histories may explain some of the risk for smoking among gay/bisexual men. Methods Patients at a Boston community health center were invited to complete a 25-item questionnaire assessing demographics, general health, trauma history, and substance use. Of the 3,103 who responded, 1309 identified as male and gay or bisexual (82.8% White and mean age of 38.55 [sd = 9.76]). Results A multinomial logistic regression with current and former smoking status as the outcome (never smoked as referent group) and covariates of age, education, employment, HIV status, and race, showed that the number of sexual minority stressors/traumas were significantly related to the odds of both current and former smoking. In comparison to participants with no trauma history, those who reported 1, 2, 3, and 4 traumas had respectively 1.70 (OR=1.70: 95% CI: 1.24-2.34), 2.19 (OR=2.19: 95% CI: 1.48-3.23), 2.88 (OR=2.88: 95% CI: 1.71-4.85), and 6.94 (OR=6.94: 95% CI: 2.62-18.38) the odds of identifying as a current smoker. Adjusted logistic regression analysis revealed a significant dose effect of number of sexual minority stressors/traumas with odds of ever smoking. Experiencing intimate partner violence, anti-gay verbal attack, anti-gay physical attack, and childhood sexual abuse were each independently associated with increased odds of the smoking outcomes. Conclusion A sexual minority specific trauma history may represent a vulnerability for smoking among gay/bisexual men. Interventions that address trauma may enhance the efficacy of smoking cessation programs and improve the mental health of gay/bisexual men. PMID:25754971

    Secondhand smoke (SHS) exposure is responsible for numerous diseases of the lungs and other bodily systems among children. In addition to the adverse health effects of SHS exposure, studies show that children exposed to SHS are more likely to smoke in adolescence. Susceptibility to smoking is a measure used to identify adolescent never-smokers who are at risk for smoking. Limited research has been conducted on the influence of SHS on susceptibility to smoking. The purpose of this study was to determine a robust measure of the strength of correlation between SHS exposure and susceptibility to smoking among never-smoking U.S. adolescents. This study used data from the 2009 National Youth Tobacco Survey to identify predictors of susceptibility to smoking in the full (pre-match) sample of adolescents and a smaller (post-match) sample created by propensity score matching. Results showed a significant association between SHS exposure and susceptibility to smoking among never-smoking adolescents in the pre-match (OR=1.47) and post-match (OR=1.52) samples. The odds ratio increase after matching suggests that the strength of the relationship was underestimated in the pre-match sample. Other significant correlates of susceptibility to smoking identified include: gender, race/ethnicity, personal income, smoke-free home rules, number of smoking friends, perception of SHS harm, perceived benefits of smoking, and exposure to pro-tobacco media messages. The use of propensity score matching procedures reduced bias in the post-match sample, and provided a more robust estimate of the influence of SHS exposure on susceptibility to smoking, compared to the pre-match sample estimates.

    Between 2001–2005, U.S. Blacks experienced a 32% higher pancreatic cancer death rate than Whites. Smoking, diabetes, and family history may explain some of this disparity, but prospective analyses are warranted. From 1984–2004, there were 6,243 pancreatic cancer deaths among Blacks (n=48,252) and Whites (n=1,011,864) in the Cancer Prevention Study II cohort. Multivariate Cox proportional hazards models yielded hazards ratios for known and suspected risk factors. Population attributable risks were computed and their impact on age-standardized mortality rates evaluated. Blacks in this cohort had a 42% increased risk of pancreatic cancer mortality compared to Whites (HR=1.42; 95% CI 1.28 to 1.58). Current smoking increased risk by >60% in both races; although Blacks smoked less intensely, risks were similar to Whites (HRBlack=1.67, 95% CI 1.28 to 2.18; HRWhite=1.82, 95%CI 1.7 to 1.95). Obesity was significantly associated with pancreatic cancer mortality in Black men (HR=1.66, 95% CI 1.05 to 2.63), White men (HR=1.42; 95% CI 1.25 to 1.60) and White women (HR=1.37; 95% CI 1.22 to 1.54); results were null in Black women. The PAR due to smoking, family history, diabetes, cholecystectomy, and overweight/obesity was 24.3% in Whites and 21.8% in Blacks. Smoking and overweight/obesity play a substantial a role in pancreatic cancer. Variation in the impact of these factors underscores the need to evaluate disease on the race-sex level. The inability to attribute excess disease in Blacks to currently known risk factors, even when combined with suspected risks, points to yet undetermined factors that play a role in the disease process.

    Races may exist in humans in a cultural sense, but biological concepts of race are needed to access their reality in a non-species-specific manner and to see if cultural categories correspond to biological categories within humans. Modern biological concepts of race can be implemented objectively with molecular genetic data through hypothesis-testing. Genetic data sets are used to see if biological races exist in humans and in our closest evolutionary relative, the chimpanzee. Using the two most commonly used biological concepts of race, chimpanzees are indeed subdivided into races but humans are not. Adaptive traits, such as skin color, have frequently been used to define races in humans, but such adaptive traits reflect the underlying environmental factor to which they are adaptive and not overall genetic differentiation, and different adaptive traits define discordant groups. There are no objective criteria for choosing one adaptive trait over another to define race. As a consequence, adaptive traits do not define races in humans. Much of the recent scientific literature on human evolution portrays human populations as separate branches on an evolutionary tree. A tree-like structure among humans has been falsified whenever tested, so this practice is scientifically indefensible. It is also socially irresponsible as these pictorial representations of human evolution have more impact on the general public than nuanced phrases in the text of a scientific paper. Humans have much genetic diversity, but the vast majority of this diversity reflects individual uniqueness and not race. PMID:23684745

    The objective of this study is unknown if fetal sex and race modify the impact of maternal pre-pregnancy body mass index (BMI), and smoking on fetal growth. The authors studied markers of fetal growth in singleton offspring of 8,801 primiparous, normotensive women, enrolled in the Collaborative Perinatal Project. The authors tested for departures from additivity between sex/race and each predictor. The head-to-chest circumference ratio (HCC) decreased more, while birthweight and ponderal index (PI) increased more for each 1 kg/m(2) increase in pre-pregnancy BMI among term females versus males (P = 0.07, P < 0.01 and P = 0.08, interaction respectively). For term offspring of White compared with Black women, smoking independent of "dose" was associated with larger reductions in growth (165 g vs. 68 g reduction in birthweight, P < 0.01, interaction), greater reduction in fetal placental ratio (P < 0.01, interaction), PI (P < 0.01, interaction), and greater increase in HCC (P = 0.02), respectively. The association of BMI and smoking with fetal size appeared to be reversed in term versus preterm infants. Our study provides evidence that the associations of pre-pregnancy BMI and smoking are not constant across sex and race. This finding may be relevant to sex and race differences in neonatal and long term health outcomes. PMID:25030701

    OBJECTIVE To analyze the prevalence and factors associated with smoking abstinence among patients who were treated in a reference unit for smoking cessation. METHODS This cross-sectional study examined the medical records of 532 patients treated in a reference unit for smoking cessation in Belém, PA, Northern Brazil, between January 2010 and June 2012. Sociodemographic variables and those related to smoking history and treatment were analyzed. Statistical significance was set at p < 0.05. RESULTS The mean age of the participants was 50 years; 57.0% of the patients were women. The mean tobacco load was 30 packs/year, and the mean smoking duration was approximately 32 years. Most patients remained in treatment for four months. The rate of smoking abstinence was 75.0%. Regression analysis indicated that maintenance therapy, absence of relapse triggers, and lower chemical dependence were significantly associated with smoking cessation. CONCLUSIONS The smoking abstinence rate observed was 75.0%. The cessation process was associated with several aspects, including the degree of chemical dependence, symptoms of withdrawal, and period of patient follow-up in a multidisciplinary treatment program. Studies of this nature contribute to the collection of consistent epidemiological data and are essential for the implementation of effective smoking prevention and cessation strategies.

    In this study, we use the Health and Retirement Study to test whether older adult smokers, defined as those 50 years and older, respond to cigarette tax increases. Our preferred specifications show that older adult smokers respond modestly to tax increases: a $1.00 (131.6%) tax increase leads to a 3.8-5.2% reduction in cigarettes smoked per day (implied tax elasticity = -0.03 to -0.04). We identify heterogeneity in tax elasticity across demographic groups as defined by sex, race/ethnicity, education, and marital status and by smoking intensity and level of addictive stock. These findings have implications for public health policy implementation in an aging population. PMID:25721732

    As the racial composition of the population changes, intergroup interactions are increasingly common. To understand how we perceive and categorize race and the attitudes that flow from it, scientists have used brain imaging techniques to examine how social categories of race and ethnicity are processed, evaluated and incorporated in decision-making. We review these findings, focusing on black and white race categories. A network of interacting brain regions is important in the unintentional, implicit expression of racial attitudes and its control. On the basis of the overlap in the neural circuitry of race, emotion and decision-making, we speculate as to how this emerging research might inform how we recognize and respond to variations in race and its influence on unintended race-based attitudes and decisions.

    Symptom-limited, graded exercise treadmill testing was performed by 4,968 white and black adults, ages 18-30 yr, during the baseline examination for the Coronary Artery Risk Development in Young Adults (CARDIA) study. Compared with nonsmokers, the mean exercise test duration of smokers was 29-64 s shorter depending on race/gender group (all P < 0.001), but mean duration to heart rate 130 (beats.min-1) ranged from 20-50 s longer (P < 0.05). In each race/gender group, test duration to heart rates up to 150 was 15-35 s longer (P < 0.05) in smokers than in nonsmokers after adjustment for age, sum of skinfolds, hemoglobin, and physical activity score. The mean maximum heart rate was lower in smokers than in nonsmokers (difference ranging from 6.7 beats.min-1 in white men to 11.2 beats.min-1 lower in black women, P < 0.001), although maximum rating of perceived exertion was nearly identical in smokers and nonsmokers. Chronic smoking appears to blunt the heart rate response to exercise, so that exercise duration to submaximal heart rates is increased even though maximal performance is impaired. This may result from downloading of beta-receptors caused by smoking. Smoking status should be considered in the evaluation of physical fitness data utilizing submaximal test protocols, or else the fitness of smokers relative to nonsmokers is likely to be overestimated.

    2010-01-01

    Background: Sensation seeking is a strong correlate of smoking among adolescents, yet the research on mediators of this association is not well established. The proposed model of the present study includes antecedent variables (sensation seeking), mediators (perceived peer smoking, outcome expectancies including negative consequences, positive reinforcement, negative reinforcement, and appetite-and-weight control), and one outcome variable (smoking cigarettes during the past 30 days). Methods: Self-reported data obtained from Hungarian high-school students (ninth grade, N = 2,565, mean age 15.3 years, SD = 0.56) were analyzed with structural equation modeling. Before testing of the main model, the construct validity of mediators (outcome expectancy scales) was supported with confirmatory factor analysis (CFA) and structural equation modeling. The final model was tested with structural equation modeling, and the goodness-of-fit indices and the proportion of direct and indirect effects were analyzed. Results: Our mediational model had an excellent model fit, and this study supported both the proposed sensation seeking→positive and negative reinforcement→smoking behavior pathways and sensation seeking→perceived peer smoking→positive and negative reinforcement→smoking behavior pathways. The total indirect effect explains 76% of sensation seeking and smoking association. Results support the notion that positive and negative reinforcement expectancies mediate between sensation seeking and smoking. Discussion: Results support the notion that perceived peer smoking, positive and negative reinforcement expectancies mediate between sensation seeking and smoking. PMID:19959571

    Neven Sesardic has recently defended his arguments in favour of racial naturalism-the view that race is a valid biological category-in response to my criticism of his work. While Sesardic claims that a strong version of racial naturalism can survive critique, he has in fact weakened his position considerably. He concedes that conventional racial taxonomy is arbitrary and he no longer identifies 'races' as human subspecies. Sesardic now relies almost entirely on Theodosius Dobzhansky's notion of race-as-population. This weak approach to 'race'-according to which all genetic difference between populations is 'racial' and 'the races' are simply the populations we choose to call races-survived its early critiques. As it is being mobilised to support racial naturalism once more, we need to continue the debate about whether we should weaken the concept of race to mean 'population', or abandon it as a failed biological category. I argue that Sesardic's case for racial naturalism is only supported by his continued mischaracterisation of anti-realism about biological race and his appeal to Dobzhansky's authority. Rather than deflating the meaning of 'race', it should be eliminated from our biological ontology. PMID:27060241

    Objective The objective of this project was to test the short term (90 days) efficacy of an automated behavioural intervention for smoking cessation, the “1‐2‐3 Smokefree” programme, delivered via an internet website. Design Randomised control trial. Subjects surveyed at baseline, immediately post‐intervention, and 90 days later. Settings The study and the intervention occurred entirely via the internet site. Subjects were recruited primarily via worksites, which referred potential subjects to the website. Subjects The 351 qualifying subjects were notified of the study via their worksite and required to have internet access. Additionally, subjects were required to be over 18 years of age, smoke cigarettes, and be interested in quitting smoking in the next 30 days. Eligible subjects were randomly assigned individually to treatment or control condition by computer algorithm. Intervention The intervention consisted of a video based internet site that presented current strategies for smoking cessation and motivational materials tailored to the user's race/ethnicity, sex, and age. Control subjects received nothing for 90 days and were then allowed access to the programme. Main outcome measures The primary outcome measure was abstinence from smoking at 90 day follow up. Results At follow up, the cessation rate at 90 days was 24.1% (n  =  21) for the treatment group and 8.2% (n  =  9) for the control group (p  =  0.002). Using an intent‐to‐treat model, 12.3% (n  =  21) of the treatment group were abstinent, compared to 5.0% (n  =  9) in the control group (p  =  0.015). Conclusions These evaluation results suggest that a smoking cessation programme, with at least short term efficacy, can be successfully delivered via the internet. PMID:16436397

    Objective There are many factors influencing dental behavior. The relationship of smokers who smoked inside the home toward preventive care (measured as dental sealant placement) of the children living in their homes is examined in this study. Methods Data from the National Health and Nutrition Examination Surveys in 2001-2002 and in 2011-2012 were analyzed. Data included variables to someone smoking inside the home, dental sealant placement in children ages 6-less than 20 years, and sociodemographics which were obtained from a dental examination and a home interview. Results There were 3,352 eligible participants in 2001-2002 and 2,374 in 2011-2012. The unadjusted odds ratio for not having dental sealants when there was someone who smoked inside the home as compared with not having dental sealants when there was no one who smoked inside the home was 1.57 (95%CI: 1.17, 2.10) in 2001-2002. The unadjusted odds ratio was 1.56 (95% CI: 1.20, 2.03) in 2011-2012. When the data were adjusted for age, sex, race/ethnicity, insurance, and income to poverty ratio, the 2001-2002 adjusted odds ratio was 1.31 (95%CI: 0.97, 1.78). The adjusted odds ratio in 2011-2012 was 1.41 (95% CI:1.01, 1.95). Conclusions Children who lived in homes in which someone smoked inside the home were more likely to not have dental sealants compared with children who lived in homes in which no one smoked inside the home. These results are important for understanding the factors related to access to dental care issues for children. PMID:26213630

    While the association between exposure to secondhand smoke and lung cancer risk is well established, few studies with sufficient power have examined the association by histological type. In this study, we evaluated the secondhand smoke-lung cancer relationship by histological type based on pooled data from 18 case-control studies in the International Lung Cancer Consortium (ILCCO), including 2,504 cases and 7,276 controls who were never smokers and 10,184 cases and 7,176 controls who were ever smokers. We used multivariable logistic regression, adjusting for age, sex, race/ethnicity, smoking status, pack-years of smoking, and study. Among never smokers, the odds ratios (OR) comparing those ever exposed to secondhand smoke with those never exposed were 1.31 (95% CI: 1.17–1.45) for all histological types combined, 1.26 (95% CI: 1.10–1.44) for adenocarcinoma, 1.41 (95% CI: 0.99–1.99) for squamous cell carcinoma, 1.48 (95% CI: 0.89–2.45) for large cell lung cancer, and 3.09 (95% CI: 1.62–5.89) for small cell lung cancer. The estimated association with secondhand smoke exposure was greater for small cell lung cancer than for non-small cell lung cancers (OR=2.11, 95% CI: 1.11–4.04). This analysis is the largest to date investigating the relation between exposure to secondhand smoke and lung cancer. Our study provides more precise estimates of the impact of secondhand smoke on the major histological types of lung cancer, indicates the association with secondhand smoke is stronger for small cell lung cancer than for the other histological types, and suggests the importance of intervention against exposure to secondhand smoke in lung cancer prevention.

    2005-07-01

    Mainstream cigarette smoke is a complex mixture that is inhaled into the respiratory system. The physical characteristics and chemical composition of mainstream smoke are reviewed and briefly compared with that of sidestream smoke. Special attention is paid to ageing effects and artifact formation during the sampling and testing of cigarette smoke, with specific examples of artifact formation during sampling discussed (nitrogen dioxide, methyl nitrite, etc.). Historically, the generation of cigarette smoke for chemical and biological testing has been based on standard smoke generation procedures that are intended for product comparisons. More recently, emerging global regulations have called for alternative smoke generation methods, with emphasis on results relevant to conditions of product use, e.g., estimates of maximum smoke emissions. Strategies for establishing such alternative smoke generation methods are discussed and the potential effects of alternative smoking conditions on analytical accuracy and precision are addressed. Current regulatory requirements that include Hoffmann analyte analysis (i.e., constituents reported to be associated with the risks of cigarette smoking) are also summarized and the potential effect of alternative smoke generation methods on individual constituent yields considered. Finally, a limited critique of emerging regulation that relates to mainstream cigarette smoke measurements, including a discussion of recent WHO recommendations, is offered. PMID:16092717

    We assessed 12 urine metals in tobacco smoke-exposed and not exposed National Health and Nutrition Examination Survey participants. Our analysis included age, race/ethnicity, and poverty status. Gender and racial/ethnic differences in cadmium and lead and creatinine-adjusted and unadjusted data for group comparisons are presented. Smokers’ had higher cadmium, lead, antimony, and barium levels than nonsmokers. Highest lead levels were in the youngest subjects. Lead levels among adults with high second-hand smoke exposure equaled smokers. Older smokers had cadmium levels signaling the potential for cadmium-related toxicity. Given the potential toxicity of metals, our findings complement existing research on exposure to chemicals in tobacco smoke. PMID:19742163

    Objectives The aim of this study was to examine the levels of serum 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and evaluate their association with age, body mass index, smoking, military record-based variables, and estimated exposure to Agent Orange in Korean Vietnam veterans. Methods Serum levels of TCDD were analyzed in 102 Vietnam veterans. Information on age, body mass index, and smoking status were obtained from a self-reported questionnaire. The perceived exposure was assessed by a 6-item questionnaire. Two proximity-based exposures were constructed by division/brigade level and battalion/company level unit information using the Stellman exposure opportunity index model. Results The mean and median of serum TCDD levels was 1.2 parts per trillion (ppt) and 0.9 ppt, respectively. Only 2 Vietnam veterans had elevated levels of TCDD (>10 ppt). The levels of TCDD did not tend to increase with the likelihood of exposure to Agent Orange, as estimated from either proximity-based exposure or perceived self-reported exposure. The serum TCDD levels were not significantly different according to military unit, year of first deployment, duration of deployment, military rank, age, body mass index, and smoking status. Conclusions The average serum TCDD levels in the Korean Vietnam veterans were lower than those reported for other occupationally or environmentally exposed groups and US Vietnam veterans, and their use as an objective marker of Agent Orange exposure may have some limitations. The unit of deployment, duration of deployment, year of first deployment, military rank, perceived self-reported exposure, and proximity-based exposure to Agent Orange were not associated with TCDD levels in Korean Vietnam veterans. Age, body mass index and smoking also were not associated with TCDD levels. PMID:24137525

    Background: There are few articles studding the factors associated with successful smoking cessation in Iranian smokers. The aim of this study is to clarify the association between socio-demographic factors and smoking behavior, such as number of failed smoking cessation and duration of abstinence in Iranian population. Methods: A self-administered questionnaire survey of 673 participants was conducted in a local government health-care center. The questionnaire included items on socio-demographic information including, age, marital status, education, income, and job. Furthermore, information on smoking cigarettes including number of smoking per day, duration of smoking, cigarettes brand, nicotine concentration, and history of cessation was obtained. Results: Mean ± SD of age and daily cigarette consumption were 39.7 ± 1.1 and 22.1 ± 1.1 respectively. Failure rate of smoking cessation was higher in the lower age group (odds ratios [OR] 2.9; 95% confidence intervals [CI] 1.1, 7.7) and less than 10 numbers smoking per day (OR 2.4; 95% CI 1.3, 4.5) and duration of smoking more than 30 years (OR 3.4; 95% CI 1.2, 9.3) and foreign cigarette brand (OR 1.8; 95% CI 1.1, 2.7). Length time of cessation was prominent in participants with lower age group (OR 5.4; 95% CI 1.3, 22.1), and less than 10 numbers smoking per day (OR 2.7; 95% CI 1.5, 4.9) and lower in smokers with duration of smoking more than 10 and 10-19 years (OR 0.32; 95% CI 0.12, 0.89), (OR 0.34; 95% CI 0.17, 0.76), respectively. Conclusions: The above results suggest that there are a significant association between socio-demographic factors and smoking-related behaviors in the Iranian population, consistent with previous reports world-wide. These factors should be considered to have appropriate public-health and policy response. PMID:23776723

    2015-01-01

    A growing body of social science research has sought to conceptualize race as a multidimensional concept in which context, societal relations, and institutional dynamics are key components. Utilizing a specially designed survey, we develop and use multiple measures of race (skin color, ascribed race, and discrimination experiences) to capture race as “lived experience” and assess their impact on Latinos’ self-rated health status. We model these measures of race as a lived experience to test the explanatory power of race, both independently and as an integrated scale with categorical regression, scaling, and dimensional analyses. Our analyses show that our multiple measures of race have significant and negative effects on Latinos’ self-reported health. Skin color is a dominant factor that impacts self-reported health both directly and indirectly. We then advocate for the utilization of multiple measures of race, adding to those used in our analysis, and their application to other health and social outcomes. Our analysis provides important contributions across a wide range of health, illness, social, and political outcomes for communities of color. PMID:26681972

    Objectives. We determined the impact of smoke-free municipal public policies on hospitalizations for chronic obstructive pulmonary disease (COPD). Methods. We conducted a secondary analysis of hospital discharges with a primary diagnosis of COPD in Kentucky between July 1, 2003, and June 30, 2011 using Poisson regression. We compared the hospitalization rates of regions with and without smoke-free laws, adjusting for personal and population covariates, seasonality, secular trends over time, and geographic region. Results. Controlling for covariates such as sex, age, length of stay, race/ethnicity, education, income, and urban–rural status, among others, we found that those living in a community with a comprehensive smoke-free law or regulation were 22% less likely to experience hospitalizations for COPD than those living in a community with a moderate–weak law or no law. Those living in a community with an established law were 21% less likely to be hospitalized for COPD than those with newer laws or no laws. Conclusions. Strong smoke-free public policies may provide protection against COPD hospitalizations, particularly after 12 months, with the potential to save lives and decrease health care costs. PMID:24825207

    The authors prospectively examined whether caffeine intake was associated with lower risk of Parkinson disease (PD) in both men and women among 304,980 participants in the National Institutes of Health-AARP Diet and Health Study and whether smoking affected this relation. Multivariate odds ratios and 95% confidence intervals were derived from logistic regression models. Higher caffeine intake as assessed in 1995–1996 was monotonically associated with lower PD risk (diagnosed in 2000–2006) in both men and women. After adjustment for age, race, and physical activity, the odds ratio comparing the highest quintile of caffeine intake with the lowest was 0.75 (95% confidence interval: 0.60, 0.94; Ptrend = 0.005) for men and 0.60 (95% confidence interval: 0.39, 0.91; Ptrend = 0.005) for women. Further adjustment for duration of smoking and analyses carried out among never smokers showed similar results. A joint analysis with smoking suggested that smoking and caffeine may act independently in relation to PD risk. Finally, the authors conducted a meta-analysis of prospective studies and confirmed that caffeine intake was inversely associated with PD risk in both men and women. These findings suggest no gender difference in the relation between caffeine and PD. PMID:22505763

    Interactions between smoking and neighborhood-level socioeconomic status (SES) as risk factors for higher polycyclic aromatic hydrocarbon (PAH) DNA adduct levels in prostate tissue were investigated. PAH-DNA adducts were measured by immunohistochemistry with staining intensity measured in optical density units by semiquantitative absorbance image analysis in tumor adjacent tissue from 400 prostatectomy specimens from the Henry Ford Health System in Detroit. For each subject, their U.S. Census tract of residence was classified as being of higher or lower SES using the median value of the distribution of the proportion of tract residents with a high-school education. Generalized estimating equation models were used to assess interactions between neighborhood-level SES and smoking status, adjusting for race, age, education level, tumor volume, primary Gleason grade and prostate specific antigen (PSA) at diagnosis. There was a statistical interaction (P = 0.004) between tract-level SES and smoking status. In lower SES tracts smoking status was not associated with adduct staining, but in higher SES tracts adduct staining intensity was 13% (P = 0.01) higher in ever-smokers as compared to never-smokers. Among never-smokers, living in a lower SES tract was associated with a 25% higher mean staining intensity (P < 0.001). Neighborhood SES modifies the association between individual smoking status and PAH-DNA adduct levels in prostate tissue. PMID:22467358

    2014-12-01

    Faces convey a wealth of social signals, including race, expression, identity, age and gender, all of which have attracted increasing attention from multi-disciplinary research, such as psychology, neuroscience, computer science, to name a few. Gleaned from recent advances in computer vision, computer graphics, and machine learning, computational intelligence based racial face analysis has been particularly popular due to its significant potential and broader impacts in extensive real-world applications, such as security and defense, surveillance, human computer interface (HCI), biometric-based identification, among others. These studies raise an important question: How implicit, non-declarative racial category can be conceptually modeled and quantitatively inferred from the face? Nevertheless, race classification is challenging due to its ambiguity and complexity depending on context and criteria. To address this challenge, recently, significant efforts have been reported toward race detection and categorization in the community. This survey provides a comprehensive and critical review of the state-of-the-art advances in face-race perception, principles, algorithms, and applications. We first discuss race perception problem formulation and motivation, while highlighting the conceptual potentials of racial face processing. Next, taxonomy of feature representational models, algorithms, performance and racial databases are presented with systematic discussions within the unified learning scenario. Finally, in order to stimulate future research in this field, we also highlight the major opportunities and challenges, as well as potentially important cross-cutting themes and research directions for the issue of learning race from face.

    Objective To examine associations between occupation and lung cancer by gender and race. Methods We used data from the Maryland Lung Cancer Study of nonsmall cell lung carcinoma (NSCLC), a multicenter case control study, to estimate odds ratios (ORs) of NSCLC in different occupations. Results After adjusting for smoking, environmental tobacco smoke, and other covariates, NSCLC ORs among women but not men were elevated in clerical-sales, service, and transportation-material handling occupations; ORs were significantly increased in all three categories (OR [95% confidence interval]: 4.07 [1.44 to 11.48]; 5.15 [1.62 to 16.34]; 7.82 [1.08 to 56.25], respectively), among black women, but only in transportation-material handling occupations (OR [95% confidence interval[: 3.43 [1.02 to 11.50]) among white women. Conclusions Women, especially black women, in certain occupations had increased NSCLC ORs. PMID:18849762

    Surgical sterilization is a relatively permanent form of contraception that has been disproportionately used by Black, Hispanic, and Native American women in the United States in the past. We use a nationally representative sample of 4,609 women ages 25 to 45 to determine whether sterilization continues to be more common and consequential by race for reproductive-age women. Results indicate that Native American and Black women are more likely to be sterilized than non-Hispanic White women, and Hispanic and Native American women are more likely than non-Hispanic White women to report that their sterilization surgeries prevent them from conceiving children they want. Reasons for sterilization differ significantly by race. These findings suggest that stratified reproduction has not ended in the United States and that the patterns and consequences of sterilization continue to vary by race. PMID:25592919

    BACKGROUND Invasive cervical cancer is thought to decline in women over 65 years old, the age at which cessation of routine cervical cancer screening is recommended. However, national cervical cancer incidence rates do not account for the high prevalence of hysterectomy in the United States. METHODS Using estimates of hysterectomy prevalence from the Behavioral Risk Factor Surveillance System (BRFSS), hysterectomy-corrected age-standardized and age-specific incidence rates of cervical cancer were calculated from the Surveillance, Epidemiology, and End Results (SEER) 18 registry in the United States from 2000 to 2009. Trends in corrected cervical cancer incidence across age were analyzed using Joinpoint regression. RESULTS Unlike the relative decline in uncorrected rates, corrected rates continue to increase after age 35–39 (APCCORRECTED = 10.43) but at a slower rate than in 20–34 years (APCCORRECTED = 161.29). The highest corrected incidence was among 65- to 69-year-old women, with a rate of 27.4 cases per 100,000 women as opposed to the highest uncorrected rate of 15.6 cases per 100,000 aged 40 to 44 years. Correction for hysterectomy had the largest impact on older, black women given their high prevalence of hysterectomy. CONCLUSIONS Correction for hysterectomy resulted in higher age-specific cervical cancer incidence rates, a shift in the peak incidence to older women, and an increase in the disparity in cervical cancer incidence between black and white women. Given the high and nondeclining rate of cervical cancer in women over the age of 60 to 65 years, when women are eligible to exit screening, risk and screening guidelines for cervical cancer in older women may need to be reconsidered.

    Cigarette smoking and the use of smokeless tobacco both cause substantial morbidity and premature mortality. The concurrent use of these products might increase dependence and the risk for tobacco-related disease and death. State-specific estimates of prevalence and relative percent change in current cigarette smoking, smokeless tobacco use, and concurrent cigarette smoking and smokeless tobacco use among U.S. adults during 2011-2013, developed using data from the Behavioral Risk Factor Surveillance System (BRFSS), indicate statistically significant (p<0.05) changes for all three behaviors. From 2011 to 2013, there was a statistically significant decline in current cigarette smoking prevalence overall and in 26 states. During the same period, use of smokeless tobacco significantly increased in four states: Louisiana, Montana, South Carolina, and West Virginia; significant declines were observed in two states: Ohio and Tennessee. In addition, the use of smokeless tobacco among cigarette smokers (concurrent use) significantly increased in five states (Delaware, Idaho, Nevada, New Mexico, and West Virginia). Although annual decreases in overall cigarette smoking among adults in the United States have occurred in recent years, there is much variability in prevalence of cigarette smoking, smokeless tobacco, and concurrent use across states. In 2013, the prevalence ranged from 10.3% (Utah) to 27.3% (West Virginia) for cigarette smoking; 1.5% (District of Columbia and Massachusetts) to 9.4% (West Virginia) for smokeless tobacco; and 3.1% (Vermont) to 13.5% (Idaho) for concurrent use. These findings highlight the importance of sustained comprehensive state tobacco-control programs funded at CDC-recommended levels, which can accelerate progress toward reducing tobacco-related disease and deaths by promoting evidence-based population-level interventions. These interventions include increasing the price of tobacco products, implementing comprehensive smoke-free laws

    The aim of this study was to estimate the prevalence of smoking and to describe the habits, attitudes, and practices related to smoking among students of Jordan University of Science and Technology (JUST), Irbid, Jordan. Students (n = 650) were recruited in randomly selected, cluster samples drawn from the medical and engineering colleges of JUST. They were made familiar with a modified Arabic version of the World Health Organisation Smoking Questionnaire and the Attitudes towards Smoking Questionnaire to study their habits, attitudes, and beliefs in relation to smoking. The study revealed that the prevalence of smoking was 28.6% (50.2% among males and 6.5% among females). Friends, not family, were the main source of the first smoking, and this most often occurred after 15 years of age (82.3%). Males preferred smoking in the cafeteria, females in the bathroom. The main advantage of smoking for males was calming down, while for females it was independence. Non-smokers chose not to smoke because of health and hatred of the habit. The non-smokers had more positive attitudes against smoking and were more aware of the adverse effects of smoking. The reasons smokers gave for starting smoking were pleasure, followed by stress and curiosity. Two-thirds of smokers intended to quit smoking in the future. Some smokers disagreed with some criticisms against smoking, and reasons why they did not want to quit included social attitudes, addiction, and not knowing how to quit. Results of this study may provide baseline data to develop an anti-smoking program in the university and encourage policy makers to limit smoking in the university by strengthening the policies against smoking.

    A case-control study of 480 patients with invasive cervical cancer and 797 population controls, conducted in five geographic areas in the United States, included an evaluation of the relationship of several cigarette smoking variables to cervical cancer risk. Although smoking was correlated with both age at first intercourse and number of sexual partners, a significant smoking-related risk persisted for squamous cell carcinoma after adjustment for these factors (relative risk, 1.5). Twofold excess risks were seen for those smoking 40 or more cigarettes per day and those smoking for 40 or more years. Increased risks, however, were observed only among recent and continuous smokers. In contrast to squamous cell cancer, no relationship was observed between smoking and risk of adenocarcinoma or adenosquamous carcinoma. These results suggest a causal relationship between cigarette smoking and invasive squamous cell cervical cancer, perhaps through a late-stage or promotional event, although the mechanisms of action require further elucidation.

    DNA methylation is a complex, tissue-specific phenomenon that can reflect both endogenous factors and exogenous exposures. Buccal brushings represent an easily accessible source of DNA, which may be an appropriate surrogate tissue in the study of environmental exposures and chronic respiratory diseases. Buccal brushings were obtained from a subset of current and former smokers from the COPDGene study. Genome-wide DNA methylation data were obtained in the discovery cohort (n = 82) using the Illumina HumanMethylation450K array. Empirical Bayes methods were used to test for differential methylation by current smoking status at 468,219 autosomal CpG sites using linear models adjusted for age, sex, and race. Pyrosequencing was performed in a nonoverlapping replication cohort (n = 130). Current smokers were significantly younger than former smokers in both the discovery and replication cohorts. Seven CpG sites were associated with current smoking at a false discovery rate less than 0.05 in the discovery cohort. Six of the seven significant sites were pyrosequenced in the replication cohort; five CpG sites, including sites annotated to CYP1B1 and PARVA, were replicated. Correlations between cumulative smoke exposure and time since smoking cessation were observed in a subset of the significantly associated CpG sites. A significant correlation between reduced lung function and increased radiographic emphysema with methylation at cg02162897 (CYP1B1) was observed among female subjects. Site-specific methylation of DNA isolated from buccal mucosa is associated with exposure to cigarette smoke, and may provide insights into the mechanisms underlying differential susceptibility toward the development of smoking-related chronic respiratory diseases.

    IMPORTANCE Substantial progress has been made in cancer diagnosis and treatment, resulting in a steady improvement in cancer survival. The degree of improvement by age, race and sex remains unclear. OBJECTIVE to quantify the degree of survival improvement over time by age, race and sex in the United States. DESIGN Longitudinal analyses of cancer follow-up data. SETTING Cancer diagnosis data for 1990–2009 and follow-up data to 2010 from nine population-based registries, part of the NCI Surveillance, Epidemiology, and End Results (SEER) program. PARTICIPANTS Approximately 1.02 million patients from SEER registries diagnosed with cancer of the colon/rectum, breast, prostate, lung, liver, pancreas, or ovary from 1990–2009. MAIN OUTCOME MEASURES Hazard ratios (HRs) and 95% confidence intervals (CIs) for cancer-specific death were estimated for patients diagnosed with any of these cancers during, 1995–1999, 2000–2004, and 2005–2009, compared diagnoses in 1990–1994. RESULTS Significant improvements in survival were found for cancers of the colon/rectum, breast, prostate, lung, and liver. Improvements were more pronounced for younger patients. For example, for patients aged 50–64 and diagnosed between 2005–2009, adjusted HRs (95%CI) were 0.57 (0.55–0.60), 0.48 (0.45–0.51), 0.61 (0.57–0.68), and 0.32 (0.30–0.36), for cancer of the colon/rectum, breast, liver and prostate, respectively, compared with the same age group of patients diagnosed during 1990–94. However, the corresponding HRs (95% CIs) for elderly patients (aged 75–85) were only 0.88 (0.84–0.82), 0.88 (0.84–0.92), 0.76 (0.69–0.84), and 0.65 (0.61–0.70), for the same four cancer sites, respectively. A similar, although weaker, age-related period effect was observed for lung and pancreatic cancers. The adjusted HRs (95%CIs) for lung cancer were 0.75 (95%CI, 0.73–0.77) and 0.84 (95%CI, 0.81–0.86), respectively, for patients aged 50 to 64 years and 75 to 85 years diagnosed

    Mounting evidence links prenatal exposure to maternal tobacco smoking with disruption of DNA methylation (DNAm) profile in the blood of infants. However, data on the postnatal stability of such DNAm signatures in childhood, as assessed by Epigenome Wide Association Studies (EWAS), are scarce. Objectives of this study were to investigate DNAm signatures associated with in utero tobacco smoke exposure beyond the 12th week of gestation in whole blood of children at age 5.5 years, to replicate previous findings in young European and American children and to assess their biological role by exploring databases and enrichment analysis. DNA methylation was measured in blood of 366 children of the multicentre European Childhood Obesity Project Study using the Illumina Infinium HM450 Beadchip (HM450K). An EWAS was conducted using linear regression of methylation values at each CpG site against in utero smoke exposure, adjusted for study characteristics, biological and technical effects. Methylation levels at five HM450K probes in MYO1G (cg12803068, cg22132788, cg19089201), CNTNAP2 (cg25949550), and FRMD4A (cg11813497) showed differential methylation that reached epigenome-wide significance according to the false-discovery-rate (FDR) criteria (q-value<0.05). Whereas cg25949550 showed decreased methylation (-2% DNAm ß-value), increased methylation was observed for the other probes (9%: cg12803068; 5%: cg22132788; 4%: cg19089201 and 4%: cg11813497) in exposed relative to non-exposed subjects. This study thus replicates previous findings in children ages 3 to 5, 7 and 17 and confirms the postnatal stability of MYO1G, CNTNAP2 and FRMD4A differential methylation. The role of this differential methylation in mediating childhood phenotypes, previously associated with maternal smoking, requires further investigation. PMID:27171005

    Introduction Smoking is among the leading causes of premature mortality and preventable death in the United States. Although smoking contributes to the probability of developing chronic illness, little is known about the relationship between quitting smoking and the presence of chronic illness. The present study investigated the association between diagnoses of one or more chronic diseases (diabetes, hypertension, or high cholesterol) and smoking status (former or current smoker). Methods The data analyzed were a subset of questions from a 155-item telephone-administered community survey that assessed smoking status, demographic characteristics, and presence of chronic disease. The study sample consisted of 3,802 randomly selected participants. Results Participants with diabetes were more likely to report being former smokers, after adjusting for sociodemographic characteristics, whereas having hypertension or high cholesterol was not associated significantly with smoking status. The likelihood of being a former smoker did not increase as number of diagnosed chronic diseases increased. Participants who were women, older (aged 65+), or single were significantly less likely to be former smokers. Participants with at least a college degree, those with incomes of US$50,000+, and those who were underweight or obese were more likely to be former smokers. Discussion These findings were inconsistent with research that has suggested that having a chronic illness or experiencing a serious medical event increases the odds of smoking cessation. Supporting prior research, we found that being male, having a higher income, and being obese were associated with greater likelihood of being a former smoker. PMID:19516050

    The study examined the prevalence and correlates of heavy smoking and nicotine dependence in adolescents with bipolar and cannabis use disorders. Participants were 80 adolescents between 13 and 22 years of age with co-occurring bipolar I disorder and cannabis abuse or dependence who reported ever trying a cigarette. Diagnostic and symptom severity measures were completed as part of the baseline assessments for a clinical trial. Almost half (49%) of these participants who ever tried a cigarette were current heavy smokers (≥10 cigarettes/day), and 70% met DSM-IV-TR lifetime criteria for nicotine dependence. Heavy smoking was associated with older age, heavier marijuana use and greater compulsive craving, lifetime diagnoses of attention-deficit/hyperactivity disorder, conduct disorder, illicit drug use disorders, and poorer overall functioning. Nicotine dependence was related to White race, higher current mania severity, and poorer overall functioning. These findings suggest that heavy smoking and nicotine dependence were highly prevalent among these adolescents. Although both were associated with greater physical and psychosocial problems, only heavy smoking was linked to a clear pattern of more severe substance-related and psychiatric problems. Further research to elucidate mechanisms and develop interventions to address early, entrenched patterns of co-use of tobacco and marijuana is warranted. PMID:23684537

    Objective: To investigate whether passive cigarette smoke exposure increases the risk of invasive pneumococcal disease in children. Methods: In a population-based case-control study, 171 children aged 0 to 12 years with culture-confirmed invasive pneumococcal disease during the years 1994 to 2004 were identified. Two controls were matched to each case on age and patterns of Health Plan membership. We reviewed medical records of subjects and family members for information on household cigarette smoke exposure within 2 years of the diagnosis of invasive pneumococcal disease. We collected information on sex, race, pneumococcal vaccination, selected medical conditions, and medications in the 3 months before the diagnosis. Results: Similar proportions of cases (25%) and controls (30%) had definite or probable passive smoke exposure (odds ratio [OR] = 0.76, 95% confidence interval [CI] = 0.47–1.2). Cases of invasive pneumococcal disease were more likely to be nonwhite than controls (OR = 4.4, 95% CI = 2.3–8.2). Elevated risk of invasive pneumococcal disease was found in subjects with recent pulmonary diagnoses (OR = 2.2, 95% CI = 1.2–4.0) and recent antibiotic use (OR = 1.6, 95% CI = 1.1–2.3). Conclusions: Passive cigarette smoke exposure was not associated with invasive pneumococcal disease in this pediatric population. Invasive pneumococcal disease was associated with recent pulmonary diagnoses and recent antibiotic use. PMID:25431997

    The essays here reconsider some of the basal assumptions in Nancy Stepan's now-classic The Idea of Race in Science (1982). Stepan's book focused, for the most part, on metropolitan scientists from 1800 to 1960. The present contributions seek to "relocate" race along one (at least) of three axes: discipline, geography, period. The aim overall is not so much to make the fairly obvious point that "racial" thinking was different in different times and places; rather, the essays seek to use accounts of the relocation of race to "make strange" our assumptions about the conditions of possibility for nineteenth- and early twentieth-century race science in its once-canonical form.

    2005-01-01

    In this article, the authors argue that the overwhelming portion of the literature on intelligence, race, and genetics is based on folk taxonomies rather than scientific analysis. They suggest that because theorists of intelligence disagree as to what it is, any consideration of its relationships to other constructs must be tentative at best. They further argue that race is a social construction with no scientific definition. Thus, studies of the relationship between race and other constructs may serve social ends but cannot serve scientific ends. No gene has yet been conclusively linked to intelligence, so attempts to provide a compelling genetic link of race to intelligence are not feasible at this time. The authors also show that heritability, a behavior-genetic concept, is inadequate in regard to providing such a link. PMID:15641921

    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

    Background The use of race as a variable in research continues to spark debate about whether it should be used, as well as the implications it has for research on health differences. Given this continued controversy, we examined how investigators interpret the concept of “race” and whether their views of race are reflected in their published work. Methods Thirty-three semistructured interviews were conducted with investigators from 3 southeastern universities to discuss recruitment of participants, the use of race as a variable in research and analyses, and their assessment of the National Institutes of Health mandate on the inclusion of women and minorities. The interview data were analyzed using the principles of constant comparative method, theme identification and pattern investigation. Up to 2 publications for each respondent were also used to assess the use of race in their research. Results Results reflect a spectrum of views on the definition of race, from biological to social. Findings also suggest that investigators think critically about the use and implications of using race in their research, although this is not consistently reflected in their published work. Conclusion In our view, authors, journal editors and peer reviewers have an important role in moving this debate forward, and advocate that they engage more directly in shaping the process. When reporting results by race, investigators should provide a statement on the theory or conceptual framework underlying the hypothesized racial differences in health examined in the study. They should be also cautious in invoking either biological or social constructions of race, thus demonstrating an appreciation of the nuances and implications of using this variable. PMID:18942287

    The NHANES 2003-2006 has assessed iron and iodine status, 2 trace element nutrients of continued public health interest, in the U.S. population. We investigated associations of sociodemographic (age, sex, race-ethnicity, education, income) and lifestyle (smoking, alcohol consumption, BMI, physical activity, dietary supplement use) variables with the iron status indicators serum ferritin, soluble transferrin receptor (sTfR), and body iron in women aged 20-49 y (n = 2539, 2513, and 2509, respectively) and with urine iodine, a biomarker of iodine intake, in adults aged ≥ 20 y (n = 3066). Significant correlations between the study variables and biomarkers were weak (|r| ≤ 0.24). Urine creatinine (uCr) was moderately significantly correlated with urine iodine (r = 0.52). The individual variables explained ≤ 5% of the variability in biomarker concentrations in bivariate analysis. In multiple regression models, sociodemographic and lifestyle variables together explained 4-13% of the variability in iron indicators and 41% of the variability in urine iodine (uCr in the model). The adjusted estimated body iron was ≈ 1 unit (mg/kg) lower in non-Hispanic black vs. non-Hispanic white women and ≈ 1 unit higher in women who smoked vs. those who did not and in women consuming 1 vs. 0 alcoholic drinks/d. The adjusted estimated urine iodine concentration (uCr in the model) was 34% lower in non-Hispanic blacks vs. non-Hispanic whites, 22% higher in supplement users vs. nonusers, and 11% higher with every 10-y increase in age. In summary, after adjusting for sociodemographic and lifestyle variables (and uCr in the iodine model), race-ethnicity retained a strong association with sTfR, body iron, and urine iodine; smoking and alcohol consumption with iron biomarkers; and supplement use and age with urine iodine.

    Perceived smoking prevalence, a strong predictor of actual smoking behavior, may be influenced by the ethnicity and gender of the reference group presented to Korean American emerging adults. Self-identifying Korean and Korean Americans aged 18-25 (N = 475), were invited to complete a 15-20 min online survey about their attitudes towards smoking. Predictors of perceived smoking prevalence were evaluated separately for four reference groups: Caucasian Americans, Korean Americans in general, Korean American men, and Korean American women. Respondents' smoking status was associated with perceived smoking prevalence for all reference groups except Caucasian Americans, even among light smokers. Father's smoking status was associated with perceived smoking prevalence for Korean American men, only among females respondents. Findings suggest that ethnicity and gender of both the reference group and respondents influence smoking rate estimates. Tailoring intervention content to the target population's gender and ethnicity may be a way to enhance smoking prevention strategies. PMID:27075031

    PubMed

    Bloche, M Gregg

    2006-01-01

    Taking notice of race is both risky and inevitable, in medicine no less than in other endeavors. On the one hand, race can be a useful stand-in for unstudied genetic and environmental factors that yield differences in disease expression and therapeutic response. Attention to race can make a therapeutic difference, to the point of saving lives. On the other hand, racial distinctions have social meanings that are often pejorative or worse, especially when these distinctions are cast as culturally or biologically fixed. I argue in this essay that we should start with a presumption against racial categories in medicine, but permit their use when it might prolong lives or meaningfully improve health. Use of racial categories should be understood as an interim step; follow-up inquiry into the factors that underlie race-correlated clinical differences is important both to improve the efficacy of clinical care and to prevent race in itself from being misunderstood as a biological determinant. If we pursue such inquiry with vigor, the pernicious effects of racial categories on public understanding can be managed. But perverse market and regulatory incentives create the danger that use of race will be "locked-in," once drugs or other therapies are approved. These incentives should be revisited. PMID:17144179

    This study examined the relationship between multiple dimensions of religious involvement and transitions of tobacco smoking abstinence, persistence, cessation and relapse over 9-10 years of follow-up in a national sample of adults in the United States. Using data provided at baseline and follow-up, participants were categorized as non-smokers, persistent smokers, ex-smokers, and relapsed smokers. Religious involvement over the two time points were categorized into combinations of "high" and "low" involvement within the domains of (a) religious attendance, (b) religious importance, (c) spiritual importance, (d) religious/spiritual comfort seeking, and (e) religious/spiritual decision-making. High levels of religious involvement across five dimensions (religious attendance, religious importance, spiritual importance, religious/spiritual comfort-seeking, and religious/spiritual decision-making) were associated with lower odds of being a persistent smoker or ex-smoker. Religious involvement was not associated with smoking cessation among smokers at baseline. Interventions to increase smoking abstinence may be more effective if they draw on ties to religious and spiritual organizations and beliefs. Meanwhile, religious involvement is unlikely to affect smoking cessation effectiveness. PMID:26093070

Given high rates of tobacco use and limited studies among Alaska Native (AN) women, we estimated associations of saliva cotinine levels with cigarette use and second-hand smoke (SHS) exposure and estimated a saliva cotinine cutoff to distinguish smoking from non-smoking pregnant AN women. Using questionnaire data and saliva cotinine, we utilized multi-variable linear regression (n = 370) to estimate cotinine associations with tobacco use, SHS exposure, demographic, and pregnancy-related factors. Additionally, we estimated an optimal saliva cotinine cutoff for indication of active cigarette use in AN pregnant women using receiver operating characteristic (ROC) curve analysis (n = 377). Saliva cotinine significantly decreased with maternal age and significantly increased with cigarettes smoked per day, SHS exposure, and number of previous full term pregnancies. Using self-reported cigarette use in the past 7 days as indication of active smoking, the area under the ROC curve was 0.975 (95 % CI: 0.960-0.990). The point closest to 100 % specificity and sensitivity occurred with a cotinine concentration of 1.07 ng/mL, which corresponded to sensitivity of 94 % and specificity of 94 %. We recommend using a saliva cotinine cutoff of 1 ng/mL to distinguish active smoking in pregnant AN women. This cutoff is lower than used in other studies with pregnant women, most likely due to high prevalence of light or intermittent smoking in the AN population. Continued study of cotinine levels in diverse populations is needed. PMID:23423858

  7. Smoking and women: tragedy of the majority.

    An increasing number of women are becoming victims of their smoking habit. A broader cross-section of women, other than the very rich and the "indecent," began to smoke in the 1920s, and over the past 50 years tobacco advertising has linked smoking with women's emancipation and achievement of equality with men. The marketing efforts directed to women include special packaging for feminine appeal, "designer" cigarettes, and offering discounted women's products with the purchase of a particular brand of cigarettes. Sponsorship of sporting events coupled with sports themes in cigarette advertisements associates smoking with enhanced physical capacity--a deception. The marketing experts promote smoking as a way of remaining slim in a culture obsessed with thinness. The woman who smokes today is a heavier smoker, on average, with the percentage of women smoking more than 25 cigarettes/day almost doubling from 13% in 1965 to 23% in 1985. Women start smoking at younger and younger ages. 84% of women smokers who are now 28-37 years began to smoke before age 20 as compared with 42% of those now 58-67 years. Today more young women than young men smoke. In addition to the risk of lung cancer, women who smoke also have sex-specific risks, such as those pertaining to a women's reproductive organs and processes. When smoking is of long duration, it appears to increase the risks of intraepithelial neoplasia of the cervix and of invasive cervical cancer. An antiestrogen effect of smoking may provide the explanation for why smoking women reach menopause 1-2 years earlier than nonsmokers. The same mechanism, which has been supported by several case-control studies, may increase postmenopausal osteoporotic fractures, particularly among nonobese women. Possibly the worst consequences of smoking by women are its effects on reproduction and on children. Both a dose-response depressant effect of smoking on fetal development and birth weight have been confirmed. Smoking also reduces

    The literature documents that personality characteristics are associated with healthy lifestyles, including smoking. Among positive traits, Positivity (POS), defined as a general disposition conducive to facing experience under a positive outlook has shown robust associations with psychological health. Thus, the present study investigated the extent to which POS is able to predict (i) relapse after quitting smoking and (ii) the desire to smoke again. All participants (481) had previously attended a Group Counselling Program (GCP) for Smoking Cessation (from 2005 through 2010). They were contacted through telephone interview. Among participants, 244 were ex-smokers (age: years 56.3 ± 10.08, 52% female) and 237 were still-smokers (age: years 55.0 ± 9.63; 63.5% female). The association of POS with “craving to smoke” levels was assessed with multivariate linear regression analysis while controlling also for important differences in personality such as conscientiousness and general self-efficacy, as well as for gender and age. Results showed that POS was significantly and negatively associated with smoking status and with craving to smoke. Among covariates (i.e., conscientiousness, generalized self-efficacy), gender was associated with smoking status and with craving to smoke. Altogether these findings corroborate the idea that POS plays a significant role in sustaining individuals' efforts to quit smoking. PMID:24967403

    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.

  12. [Woman and race biology].

    PubMed

    Hanson, H

    1993-01-01

    Early 20th century race biology takes a special interest in woman as part of the "intra-racial" project of bringing forth healthy and competitive individuals. But there are other motives as well for the race biologist to take an interest in woman. She is believed to develop fewer individual characteristics and is therefore a more typical representative of her race than man. The development level of the race is also presupposed to be discernible by the degree of "gender diformism": a race of higher standing would exhibit a greater difference between the sexes. The anthropologist, anatomist, gynaecologist--or whatever guise the race biologist may adopt-- will, in principle, stress that the relation between the sexes is not a matter of "more or less", but one of differences in kind. In reality, the "more-or-less of comparison is the very cornerstone of the issue. Quantitative differences, directly observed or obtained from statistics, are construed as signs of difference in kind. 18th century medical philosophy and sex-linked anthropology laid the theoretical foundation of the 19th century essentialist conception of woman, which is also that adopted by race biology. Eugenics of social Darwinist inspiration regarded prophylactic health care and social welfare programs with scepticism. A race biology founded on the man-woman dualism could sustain altogether different conclusions. An advanced culture calls for extensive division of labour. An extended childhood renders possible higher development but will also impose higher demands on woman. The protection of the female organism is thus an exigency for any people or race striving to survive and evolve. From society's care for the female organism health care for women and preventive maternity care will emerge. Race biology has been a preeminently German concern, as indicated by the selection of works taken to represent this perspective on woman: Bartels-Ploss' Das Weib, C.H. Stratz' Die Rassenschönheit des Weibes and

    Purpose This study aims to describe the longitudinal individual and environmental predictors of stopping smoking among a group of young adult smokers. Methods From a longitudinal population-based cohort of midwestern youth, semi-annual surveys were analyzed when study participants were between the ages of 18 and 21. Using data from 2001–2008, analyses were restricted to individuals who, at age 18, reported smoking between 1 and 30 days in the previous month (n=1,022). Generalized linear mixed modeling was used to analyze demographic, attitudinal, and social-environmental predictors of stopping smoking over time. Results After adjusting for smoking frequency at baseline, demographic and attitudinal factors that were associated with stopping smoking over time included increased age and attending college; male gender, smoking frequency and agreeing that cigarettes are calming were significantly associated with continued smoking. Social-environmental factors associated with stopping smoking over time included a household ban on smoking and living in a state with a clean indoor air policy; factors associated with continued smoking included living with a smoker and having close friends who smoke. Conclusions Both individual and social-environmental factors can serve as risk and protective factors for stopping smoking between ages 18 and 21. These factors should be used to refine more effective smoking cessation and prevention interventions in young adults. PMID:23763963

    Objectives In the present study, we aimed to determine the effect of both active and passive smoking on the prevalence of the hearing impairment and the hearing thresholds in different age groups through the analysis of data collected from the Korea National Health and Nutrition Examination Survey (KNHANES). Study Design Cross-sectional epidemiological study. Methods The KNHANES is an ongoing population study that started in 1998. We included a total of 12,935 participants aged ≥19 years in the KNHANES, from 2010 to 2012, in the present study. Pure-tone audiometric (PTA) testing was conducted and the frequencies tested were 0.5, 1, 2, 3, 4, and 6 kHz. Smoking status was categorized into three groups; current smoking group, passive smoking group and non-smoking group. Results In the current smoking group, the prevalence of speech-frequency bilateral hearing impairment was increased in ages of 40−69, and the rate of high frequency bilateral hearing impairment was elevated in ages of 30−79. When we investigated the impact of smoking on hearing thresholds, we found that the current smoking group had significantly increased hearing thresholds compared to the passive smoking group and non-smoking groups, across all ages in both speech-relevant and high frequencies. The passive smoking group did not have an elevated prevalence of either speech-frequency bilateral hearing impairment or high frequency bilateral hearing impairment, except in ages of 40s. However, the passive smoking group had higher hearing thresholds than the non-smoking group in the 30s and 40s age groups. Conclusion Current smoking was associated with hearing impairment in both speech-relevant frequency and high frequency across all ages. However, except in the ages of 40s, passive smoking was not related to hearing impairment in either speech-relevant or high frequencies. PMID:26756932

    Background Clinical manifestations and outcomes of atherosclerotic disease differ between ethnic groups. In addition, the prevalence of risk factors is substantially different. Primary prevention programs are based on data derived from almost exclusively White people. We investigated how race/ethnic differences modify the associations of established risk factors with atherosclerosis and cardiovascular events. Methods We used data from an ongoing individual participant meta-analysis involving 17 population-based cohorts worldwide. We selected 60,211 participants without cardiovascular disease at baseline with available data on ethnicity (White, Black, Asian or Hispanic). We generated a multivariable linear regression model containing risk factors and ethnicity predicting mean common carotid intima-media thickness (CIMT) and a multivariable Cox regression model predicting myocardial infarction or stroke. For each risk factor we assessed how the association with the preclinical and clinical measures of cardiovascular atherosclerotic disease was affected by ethnicity. Results Ethnicity appeared to significantly modify the associations between risk factors and CIMT and cardiovascular events. The association between age and CIMT was weaker in Blacks and Hispanics. Systolic blood pressure associated more strongly with CIMT in Asians. HDL cholesterol and smoking associated less with CIMT in Blacks. Furthermore, the association of age and total cholesterol levels with the occurrence of cardiovascular events differed between Blacks and Whites. Conclusion The magnitude of associations between risk factors and the presence of atherosclerotic disease differs between race/ethnic groups. These subtle, yet significant differences provide insight in the etiology of cardiovascular disease among race/ethnic groups. These insights aid the race/ethnic-specific implementation of primary prevention. PMID:26134404

  16. The Effect of Smoke-Free Air Law in Bars on Smoking Initiation and Relapse among Teenagers and Young Adults

    Background: Existing evidence has shown that most smoking uptake and escalation occurs while smokers are teenagers or young adults. Effective policies that reduce smoking uptake and escalation will play an important role in curbing cigarette smoking. This study aims to investigate the effect of smoke-free air (SFA) laws in bars on smoking initiation/relapse while controlling for other confounders. Methods: The national longitudinal Survey of Youth 1997 (NLSY97) from 1997–2009 was linked to state-level scores for the strength of SFA laws in order to carry out the analysis. Results and Conclusion: We find that SFA laws in bars with exemptions significantly reduce (p ≤ 0.01) the probability of smoking initiation (one-puff, daily, and heavy smoking initiation). The 100% SFA law in bars without exemption significantly deters smoking relapse from abstinence into daily smoking (p ≤ 0.05) or relapse from abstinence into heavy smoking (p ≤ 0.01) among people age 21 or older. The reduction of one-puff and daily smoking initiation is larger among ages 20 or younger than ages 21 or older, while the reduction in relapse does not differ by whether respondents reach the drinking age. Results also indicate that higher cigarette taxes significantly reduce daily smoking initiation and relapse into nondaily and light smoking. PMID:25584419

    Aim To investigate whether the association between exposure to smoking in movies and smoking among youth is independent of cultural context. Method Cross-sectional survey of 16 551 pupils recruited in Germany, Iceland, Italy, the Netherlands, Poland and Scotland with a mean age of 13.4 years (SD=1.18) and an equal gender distribution. School-based surveys were conducted between November 2009 and June 2010. Using previously validated methods, exposure to movie smoking was estimated from the 250 top-grossing movies of each country (years 2004–2009) and related to ever smoking. Results Overall, 29% of the sample had tried smoking. The sample quartile (Q) of movie smoking exposure was significantly associated with the prevalence of ever smoking: 14% of adolescents in Q1 had tried smoking, 21% in Q2, 29% in Q3 and 36% in Q4. After controlling for age, gender, family affluence, school performance, television screen time, number of movies seen, sensation seeking and rebelliousness and smoking within the social environment (peers, parents and siblings), the adjusted ORs for having tried smoking in the entire sample were 1.3 (95% CI 1.1 to 1.5) for adolescents in Q2, 1.6 (95% CI 1.4 to 1.9) for Q3 and 1.7 (95% CI 1.4 to 2.0) for Q4 compared with Q1. The adjusted relationship between ever smoking and higher movie smoking exposure levels was significant in all countries with a non-linear association in Italy and Poland. Conclusions The link between smoking in movies and adolescent smoking is robust and transcends different cultural contexts. Limiting young people's exposure to movie smoking could have important public health implications. PMID:21873322

    Abstract Background This study examined the association between social, demographic, and psychologic factors and smoking status among Appalachian Ohio women. A secondary aim examined whether specific factors could be identified and segmented for future tailored treatment of tobacco dependence. Methods A cross-sectional survey (n=570) obtained information about social, demographic, and psychologic factors and smoking. Logistic regression described associations between these characteristics and smoking status. Chi-square automatic interaction detection (CHAID) analyses identified subgroups at risk for smoking. Results Fifty-two percent never smoked, with 20.5% and 27.5% categorized as former and current smokers, respectively. Women with low adult socioeconomic position (SEP) were more likely to smoke (odds ratio [OR] 3.05, 95% confidence interval [CI] 1.74-5.34) compared to high SEP women. Other factors associated with current smoking included age 31–50 (OR 2.30, 95% CI 1.22-4.33), age 18–30 (OR 3.29, 95% CI 1.72-5.34), Center for Epidemiologic Studies Depression scale (CES-D) score≥16 (OR 1.99, 95% CI 1.31-3.05), and first pregnancy at age<20 (OR 1.74, 95% CI 1.14-2.66). The prevalence of smoking was 50% among those with four or more risk factors compared to 10% for those reporting no risk factors. CHAID analyses identified low adult SEP and depressive symptoms as the combination of risk factors most strongly associated with smoking; 49.3% of women in this subgroup currently smoked. Conclusions Low SEP in adulthood, maternal circumstances, and depressive symptoms are associated with current smoking. Tailored cessation interventions that address these risk factors should be developed and further evaluated in an attempt to reduce disparities in smoking prevalence among this vulnerable group of women.

    Issue addressed Tobacco consumption contributes to health disparities among Aboriginal Australians who experience a greater burden of smoking-related death and diseases. This paper reports findings from a baseline survey on factors associated with smoking, cessation behaviours and attitudes towards smoke-free homes among the Aboriginal population in inner and south-western Sydney. Methods A baseline survey was conducted in inner and south-western Sydney from October 2010 to July 2011. The survey applied both interviewer-administered and self-administered data collection methods. Multiple logistic regression was performed to determine the factors associated with smoking. Results Six hundred and sixty-three participants completed the survey. The majority were female (67.5%), below the age of 50 (66.6%) and more than half were employed (54.7%). Almost half were current smokers (48.4%) with the majority intending to quit in the next 6 months (79.0%) and living in a smoke-free home (70.4%). Those aged 30-39 years (AOR 3.28; 95% CI: 2.06-5.23) and the unemployed (AOR 1.67; 95% CI: 1.11-2.51) had higher odds for current smoking. Participants who had a more positive attitude towards smoke-free homes were less likely to smoke (AOR 0.79; 95% CI: 0.74-.85). Conclusions A high proportion of participants were current smokers among whom intention to quit was high. Age, work status and attitudes towards smoke-free home were factors associated with smoking. So what? The findings address the scarcity of local evidence crucial for promoting cessation among Aboriginal tobacco smokers. Targeted promotions for socio-demographic subgroups and of attitudes towards smoke-free homes could be meaningful strategies for future smoking-cessation initiatives. PMID:26235612

    The authors investigated the association between exposure to smoking in movies and the initiation and progression of adolescent smoking over time among 6,522 U.S. adolescents (between the ages of 10 and 14 years, at baseline) in a nationally representative, 4-wave random-digit-dial telephone survey. They conducted a hazard (survival) analysis testing whether exposure to movie smoking and demographic, personality, social, and structural factors predict (a) earlier smoking onset and (b) faster transition to experimental (1–99 cigarettes/lifetime) and established smoking (>100 cigarettes/lifetime). Results suggest that higher exposure to movie smoking is associated with less time to trying cigarettes for the first time (adjusted hazard ratio = 1.66; 95% CI [1.37, 2.01]) but not with faster escalation of smoking behavior following initiation (adjusted hazard ratio = 1.53; 95% CI [0.84, 2.79]). In contrast, age, peer smoking, parenting style, and availability of cigarettes in the home were predictors of earlier onset and faster transition to established smoking. Thus, the authors concluded that the effect of exposure to mass-mediated images of smoking in movies may decline once adolescents have started to smoke, whereas peers and access to tobacco remain influential.

    Factors associated with changes in the smoking behaviour of approximately 6000 schoolchildren (two cohorts aged between 10 and 12 years in 1979) over 12 months are described. They were measured twice as part of a randomized controlled trial of a smoking prevention programme. Four groups were defined: (a) those who became smokers (adopters); (b) those who remained non-smokers; (c) those who became non-smokers (quitters), and, (d) those who remained smokers. Personal and social variables were ordered using a logistic regression model according to the strength of their association with adopting and quitting smoking. Factors distinguishing adopters from children who remained nonsmokers were, being a member of the older cohort, having friends who smoke, having siblings who smoke, approving of cigarette advertising and having a relatively large amount of money to spend each week. Factors distinguishing quitters from children who continued to smoke were, having siblings who do not smoke, being a member of the younger cohort, disapproving of cigarette advertising and having a relatively small amount of money to spend each week. Initial attitude scores were indicative of future smoking behaviour and where smoking behaviour changed, attitudes also changed so that the two remained congruent. The younger cohort improved their knowledge of smoking hazards over the year irrespective of their smoking behaviour. The older cohort showed significant differences in knowledge which were dependent upon smoking category, with 1980 smokers having lower knowledge scores than non-smokers and showing an apparent decrement in their previous knowledge.

    While up to 45% of women quit smoking during pregnancy, nearly 80% return to smoking within a year after delivery. Interventions to prevent relapse have had limited success. The study objective was to understand what influences return to smoking after pregnancy among women who quit smoking during pregnancy, with a focus on the role of social networks. We conducted in-depth, semi-structured interviews during the postpartum hospital stay with women who quit smoking while pregnant. Over 300 pages of transcripts were analyzed using qualitative methods to identify common themes. Respondents [n = 24] were predominately white (63%), had at least some college education (54%) and a mean age of 26 years (range = 18-36). When reflecting on the experience of being a smoker who quit smoking during pregnancy, all participants emphasized the importance of their relationships with other smokers and the changes in these relationships that ensued once they quit smoking. Three common themes were: (1) being enmeshed in social networks with prominent smoking norms (2) being tempted to smoke by members of their social networks, and (3) changing relationships with the smokers in their social networks as a result of their non-smoking status. We found that women who quit smoking during pregnancy found themselves confronted by a change in their social network since most of those in their social network were smokers. For this reason, smoking cessation interventions may be most successful if they help women consider restructuring or reframing their social network. PMID:21989676

    Introduction Exposure to secondhand smoke has immediate adverse respiratory and cardiovascular effects. A growing body of literature examining health trends following the implementation of public smoking bans has demonstrated reductions in the rates of myocardial infarction and stroke, but there has been no extensive work examining asthma hospitalizations. The aim of this study was to determine the impact of the Michigan Smoke-Free Air Law (SFA law) on the rate of asthma hospitalizations among adults in Michigan and to determine any differential effects by race or sex. Methods Data on adult asthma hospitalizations were obtained from the Michigan Inpatient Database (MIDB). Poisson regression was used to model relative risks for asthma hospitalization following the SFA law with adjustments for sex, race, age, insurance type, and month of year. Race-based and sex-based analyses were performed. Results In the first year following implementation of the SFA law, adjusted adult asthma hospitalization rates decreased 8% (95% confidence interval [CI], 7%–10%; P < .001). While asthma hospitalization rates for both blacks and whites declined in the 12 months following implementation of the SFA law, blacks were 3% more likely to be hospitalized for asthma than whites (95% CI, 0%–7%; P = .04). The rate of decline in adult asthma hospitalizations did not differ by sex. Conclusion The implementation of the SFA law was associated with a reduction in adult asthma hospitalization rates, with a greater decrease in hospitalization rates for whites compared with blacks. These results demonstrate that the SFA law is protecting the public’s health and saving health care costs. PMID:26583573

    Cigarette smoking is a problem in all environments, including health service workers. It increases the number of ill people and accelerates death. The aim of this study was to diagnose the problem of smoking in medical staff and evaluation of this problem by patients. Research was made in hospitals and out-patient clinics in Opole by using an anonimous questionnaire. Along years there has been a decrease of smoking initiation age: 60-years-old-women had their first cigarette in 70% after them finished 18 years old, while most 30-year-old-women had it before. Every year the level of education in medical staff grows up, but the number of smokers in them does not fall down. It is still common to smoke in non-smokers and pregnant woman presence in spite of knowledge about passive smoking. Also pregnancy is not always strong argument to complete quit smoking, among medical staff as well. Smoking medical personnel has definitely negative evaluation by non-smoking patients (70%), a bit less negative it is seen by smoking patients. As the research showed, promotion of nonsmoking workers by employers could be a motivation to quit smoking. PMID:19189557

  12. Biogeographical ancestry and race.

    The use of racial and ethnic categories in biological and biomedical research is controversial-for example, in the comparison of disease risk in different groups or as a means of making use of or controlling for population structure in the mapping of genes to chromosomes. Biogeographical ancestry (BGA) has been recommended as a more accurate and appropriate category. BGA is a product of the collaboration between biological anthropologist Mark Shriver from Pennsylvania State University and molecular biologist Tony Frudakis from the now-defunct biotechnology start-up company DNAPrint genomics, Inc. Shriver and Frudakis portray BGA as a measure of the 'biological', 'genetic', 'natural', and 'objective' components of race and ethnicity, what philosophers of science would call a natural kind. This paper argues that BGA is not a natural kind that escapes social and political connotations of race and ethnicity, as Shriver and Frudakis and other proponents believe, but a construction that is built upon race-as race has been socially constructed in the European scientific and philosophical traditions. More specifically, BGA is not a global category of biological and anthropological classification but a local category shaped by the U.S. context of its production, especially the forensic aim of being able to predict the race or ethnicity of an unknown suspect based on DNA found at the crime scene. Therefore, caution needs to be exercised in the embrace of BGA as an alternative to the use of racial and ethnic categories in biological and biomedical research. PMID:24989973

    Higher childhood cancer incidence rates are generally reported for high income countries although high quality information on descriptive patterns of childhood cancer incidence for low or middle income countries is limited, particularly in Sub-Saharan Africa. There is a need to quantify global differences by cancer types, and to investigate whether they reflect true incidence differences or can be attributed to under-diagnosis or under-reporting. For the first time, we describe childhood cancer data reported to the pathology report-based National Cancer Registry of South Africa in 2000-2006 and compare our results to incidence data from Germany, a high income country. The overall age-standardized incidence rate (ASR) for South Africa in 2000-2006 was 45.7 per million children. We observed substantial differences by cancer types within South Africa by racial group; ASRs tended to be 3-4-fold higher in South African Whites compared to Blacks. ASRs among both Black and White South Africans were generally lower than those from Germany with the greatest differences observed between the Black population in South Africa and Germany, although there was marked variation between cancer types. Age-specific rates were particularly low comparing South African Whites and Blacks with German infants. Overall, patterns across South African population groups and in comparison to Germans were similar for boys and girls. Genetic and environmental reasons may probably explain rather a small proportion of the observed differences. More research is needed to understand the extent to which under-ascertainment and under-diagnosis of childhood cancers drives differences in observed rates. PMID:25363616

    Cigarette smoking is associated with cognitive decline and dementia, but the extent of the association between smoking and structural brain changes remains unclear. Importantly, it is unknown whether smoking-related brain changes are reversible after smoking cessation. We analyzed data on 504 subjects with recall of lifetime smoking data and a structural brain magnetic resonance imaging at age 73 years from which measures of cortical thickness were extracted. Multiple regression analyses were performed controlling for gender and exact age at scanning. To determine dose-response relationships, the association between smoking pack-years and cortical thickness was tested and then repeated, while controlling for a comprehensive list of covariates including, among others, cognitive ability before starting smoking. Further, we tested associations between cortical thickness and number of years since last cigarette, while controlling for lifetime smoking. There was a diffuse dose-dependent negative association between smoking and cortical thickness. Some negative dose-dependent cortical associations persisted after controlling for all covariates. Accounting for total amount of lifetime smoking, the cortex of subjects who stopped smoking seems to have partially recovered for each year without smoking. However, it took ~25 years for complete cortical recovery in affected areas for those at the mean pack-years value in this sample. As the cortex thins with normal aging, our data suggest that smoking is associated with diffuse accelerated cortical thinning, a biomarker of cognitive decline in adults. Although partial recovery appears possible, it can be a long process. PMID:25666755

    Over the last 30 years the prevalence of cigarette smoking in adults in the UK has fallen to around 30%. Smoking will still kill 100,000 people each year well into the next century. Smoking in children is related to whether their parents smoke. Moves to reduce smoking in adults will therefore reduce smoking in children. The Government should be urged to raise taxes on cigarettes and ban advertising. Smoking should be banned from all health care premises. Hospitals should be encouraged to appoint smoking cessation counsellors to work with both staff and patients. PMID:8348004

    Smoke inhalation injury causes severe morbidity and death. In the United States, the majority of fatalities from fire and burns occur because of inhalation of smoke. Medical treatment is only supportive; there is no known antidote to the damaging effects of smoke toxicants on pulmonary tissue. Without question, minimization of the morbidity and mortality that are caused by smoke inhalation is best accomplished by prevention of the injury. Effective prevention programs depend on a thorough and detailed understanding of the mechanism of damage caused by smoke, as well as of the available options for efficacious prevention. This summary presents details of smoke production from structure fires, the effects of smoke on physiology, and the devices currently in use to prevent damage and death from smoke. PMID:21785363

    The objective of this study was to evaluate how indoor pollution from tobacco and home heating may adversely affect respiratory health in young children. A total of 452 children born 1994-1996 in two districts in the Czech Republic participated. Lower respiratory illness (LRI) diagnoses occurred more frequently in children from homes heated by coal (vs. other energy sources or distant furnaces; rate ratio (RR) = 1.45; 95% confidence interval (CI), 1.07-1.97). Maternal prenatal smoking and other adult smokers also increased LRI rates (respectively: RR = 1.48; 95% CI, 1.10-2.01; and RR = 1.29; 95% CI, 1.01-1.65). Cooking fuels (primarily electricity, natural gas, or propane) were not associated with LRI incidence. For children never breast-fed, coal home heating and mother's smoking conferred substantially greater risks: RR = 2.77 (95% CI, 1.45-5.27) and RR = 2.52 (95% CI, 1.31-4.85), respectively. This maternal smoking and coal home heating increased risk for LRI in the first 3 years of life, particularly in children not breast-fed.

    Objectives. We sought to describe the prevalence of secondhand tobacco smoke incursions reported by multiunit housing (MUH) residents, pinpoint factors associated with exposure, and determine whether smoke-free building policy was associated with prevalence of reported tobacco smoke incursions. Methods. Data are from a 2011 nationally representative dual-frame survey (random-digit-dial and Internet panels) of US adults aged 18 years and older. Individuals who lived in MUH and who reported no smoking in their homes for the past 3 months, whether or not they reported being smokers themselves, were included in this study. Incursions were defined as smelling tobacco smoke in their building or unit. Results. Of 562 respondents, 29.5% reported smoke incursions in their buildings. Of these, 16% reported incursions in their own unit, 36.2% of which occurred at least weekly. Government-subsidized housing and partial smoke-free policies were associated with a higher likelihood of reporting smoke incursions. Conclusions. Many residents of multiunit housing are exposed to tobacco smoke in their units and buildings. Partial smoke-free policies do not appear to protect residents and might increase the likelihood of incursions in residents’ individual units. PMID:24922124

    Using social stress perspective, we studied the mental health effects of added burden related to socially disadvantaged status (being African-American or Latino, female, young, and identifying as bisexual versus gay or lesbian) in a community sample of 396 self-identified lesbian, gay, and bisexual (LGB) adults. Mental health outcomes were social and psychological well-being contrasted with depressive symptoms. When mental health deficiencies by disadvantaged social status were detected, we examined if LGB community connectedness and positive sexual identity valence played a mediating role, reducing the social status disparity in outcome. We found different patterns when looking at social vs. psychological well-being and positive vs. negative mental health outcomes. Bisexuality and young age, but not gender and racial/ethnic minority status, were associated with decreased social well-being. In bisexuals, this relationship was mediated by community connectedness and sexual identity valence. Though no differences in social or psychological well-being were found by gender, female gender was associated with depressed mood. We conclude that there is limited support for an additive stress model. PMID:20099941

    A questionnaire survey was administered in January 1982 to 3090 junior high school boys and girls in Nagoya, Japan. The proportion of current regular smokers who smoke at least one cigarette per week was 3.6% for boys and 0.5% for girls. By the third grade this had increased to 6.9% and 1.2% respectively for each sex. Multivariate analysis of associated social psychological factors revealed that peer smoking was most strongly related to individual smoking status. Parental smoking, sibling smoking, educational aspiration, and attitudes toward anti-smoking legislation for minors were also significantly related to smoking status. The fostering of resistance to social pressure to smoke, family involvement, strict execution of the law, and increased experiences of success in academic, social and physical activities should be considered in smoking prevention programmes for this age group.

    Although previous studies have provided strong evidence that Chinese individuals are exposed to secondhand smoke (SHS) and lack knowledge of its harmful effects, there has not been an in-depth exploration of the variability in exposure and knowledge by geographic region, occupation, and socioeconomic status. The objectives of this study were to examine: (1) the demographic factors associated with the level of knowledge of the harmful effects of smoking; (2) the factors related to implementation of in-home and workplace smoking bans; and (3) geographic differences in being exposed to SHS in government buildings, healthcare facilities, restaurants, public transportations,and schools. We used data from the 2010 Global Adult Tobacco Survey-China.Chi-square tests were used for statistical analysis. The results suggested that among Chinese citizens age 15 years and older, there is poor knowledge of the harmful effects of tobacco, and knowledge varies with region and socioeconomic status. Over three-quarters of the households had no smoking restrictions, and a large percentage of workers reported working in places with no smoking ban. In public places, exposure to SHS was high,particularly in rural areas and in the Southwest. These results suggest Chinese individuals are not well informed of smoking and SHS associated risks and are regularly exposed to SHS at home, work and public places. PMID:25587607

    Effects of cigarette smoking and smoking cessation on rate of FEV1 decline over 6 yr were examined in 4,451 Japanese-American men from the Honolulu Heart Program who were 45 to 68 yr of age at baseline (1965-1968). Within-person regression was used to calculate annual change in FEV1. Rates of FEV1 decline varied strongly with smoking status and increased significantly with age. Overall, men who continued to smoke experienced steeper rates of decline compared with men who never smoked (-33 ml/yr versus -22 ml/yr, respectively; p = 0.0001). Rates of decline for those who quit smoking during the first 2 yr (-32 ml/yr) were nearly the same as those who continued smoking (-34 ml/yr). After quitting, their rates of decline diminished to a level (-19 ml/yr) similar to that of men who had never smoked (-21 ml/yr). FEV1 decline in continuing smokers was significantly associated with duration of smoking, whereas associations with intensity and pack-years were of borderline significance. Among 216 men with impaired pulmonary function, those who quit smoking had significantly slower rates of FEV1 decline than did those who continued smoking. Potential reasons for quitting included respiratory conditions and stroke. These results extend previous reports of accelerated rates of FEV1 decline in the persons who continue to smoke, and they indicate that smoking cessation leads to less steep rates of decline in pulmonary function over a short period of time in middle-aged men, as well as in men with established pulmonary impairment.

    Introduction: In 2012 in China, 52.9% of men were reported to smoke while only 2.4% of women smoked. This study explored the smoking-related Knowledge, Attitudes and Practices (KAP) among young adult male smokers. Methods: A cross-sectional study was conducted in four municipal areas of Chongqing using a questionnaire administered to 536 natives young male smokers aged 18–45 years old. Results: The total score of smoking cognition, the total score of smoking attitude and the total score of positive behavior to quit smoking was significantly different among the three groups by education. Besides, 30.97% of male smokers never seriously thought about quitting smoking. Logistic regression analysis found smoking-related knowledge, attitudes, behaviors and sociodemographic factors affect having smoking cessation idea. But no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking in a sample of higher education. No statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.03012, p = 0.6811), and also no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.08869, p = 0.2364)  in the sample of higher education young adult males Conclusions: Young adult males with higher education have a better knowledge of smoking hazards and a more positive attitude toward smoking, however, this knowledge and attitude do not necessarily translate into health behavioral outcomes such as not smoking. Overall the present findings indicate that no statistically significant correlation between the education level and quitting smoking idea exists among young adult male smokers in China. This survey gives a snapshot of the impact of education on smoking-related KAP among young adults male smokers. PMID:25689992

    Data from National Health and Nutrition Examination Survey (NHANES) for the years 1999-2012 were used to evaluate trends in exposure to second hand smoke (SHS) at home among children aged 3-11 years and nonsmoker adolescents aged 12-19 years. A total of 12,815 children and 10,269 adolescents were included in the analyses. Serum cotinine was used as a biomarker for exposure to SHS at home. Regression models with log10 transformed values of serum cotinine as dependent variables and age, race/ethnicity, NHANES survey year, and family poverty income ratio as a surrogate measure of socioeconomic status were used in models for those with and without exposure to SHS at home. In addition, for those with exposure to SHS at home, number of smokers smoking inside home and number of cigarettes smoked at home every day were also used as independent variables. There was a biennial increase of 1.05 ng/L in adjusted serum cotinine levels for children with exposure to SHS at home over the period of 1999-2012. Serum cotinine levels among nonsmoker adolescents with exposure to SHS at home did not change over time. When there was no exposure to SHS at home, there was a statistically significant downward trend for serum cotinine levels for both children and nonsmoker adolescents. Serum cotinine levels attributable to SHS exposure increased with age among nonsmoker adolescents (p≤0.02) but decreased with age among children (p<0.01). For a unit decrease in family poverty income ratio, SHS exposure as measured by serum cotinine levels (Table 6) increased by 1.18 ng/L among children and by 1.30 ng/L among nonsmoker adolescents. In general, observed serum cotinine levels associated with SHS exposure at home were higher for children than they were for nonsmoker adolescents. PMID:26519575

    A pseudo cohort study using national cross-sections (2001, 2004, 2007, and 2010) was conducted to examine differences in smoking prevalence under different smoking ban policies such as a complete workplace indoor smoking ban (early or recent implementation) and a partial smoking ban among male public workers and husbands of female nonsmoking public workers. The effectiveness of smoking bans was estimated by difference-in-differences (DID) with age group stratification. The results varied considerably by age and implementation period. Although DID estimates (positive value of DID estimate represents smoking cessation percentage) for both smoking bans on total male smoking were not significant, the over-40 age group indicated a significant DID estimate of 5.0 (95% CI: 0.2, 9.8) for the recent smoking ban. For female workers' husbands' smoking, the over-40 age group indicated positive, but not significant, DID estimates for the early and recent smoking bans of 7.2 (−4.7, 19.2) and 8.4 (−2.0, 18.7), respectively. A complete indoor workplace smoking ban, particularly one recently implemented among public office workers aged over 40, may reduce male workers' smoking and female workers' husbands' smoking compared with a partial smoking ban, but the conclusion remains tentative because of methodological weaknesses in the study.

    Purpose To quantify the persistence of pro-smoking media exposure effects on college students’ intentions to smoke and smoking refusal self-efficacy. Method A total of 134 college students (ages 18–24) were enrolled in an ecological momentary assessment study in which they carried handheld data collection devices for three weeks and reported their exposures to pro-smoking media as they occurred in the real world. Smoking intentions and smoking refusal self-efficacy were assessed after each exposure to pro-smoking media and at random prompts during each day of the three-week assessment period. A generalized additive model was used to determine how long the effect of an exposure to pro-smoking media persisted. Results The effect of pro-smoking media exposures persisted for 7 days. After exposure, smoking intentions immediately increased (0.56; 95% confidence interval [CI]: [0.26, 0.87]) and then steadily decreased (−0.12; 95% CI: [−0.19, −0.05]) each day for 7 days, while smoking refusal self-efficacy immediately decreased (−0.42; 95% CI: [−0.75, −0.10]) and then steadily increased (0.09; 95% CI: [0.02, 0.16]) each day for 7 days. Daily changes occurring after 7 days were not statistically significant, suggesting that smoking intentions and refusal self-efficacy had stabilized and were no longer affected by pro-smoking media exposure. Conclusions Exposures to pro-smoking media may have strong implications for emerging young adults smoking risk as the impact of an individual exposure appears to persist for at least a week.

Different databases were searched (Web of Science, Google Scholar, Pub Med and Science Direct) with keywords. This search was carried out in October 2013. Studies that included were evaluated for methodological soundness by giving a quality score based on Russell and Gregory's criteria. A total 12 relevant articles were included in this review. The findings show that the prevalence of smoking is still in higher rates. The age of smoking was started among adolescents ranged from 10 to 15 years old while from university students were from 16 years old. The main reason for smoking among adolescents was influenced by friends. Among college students were peer pressure followed by the stress, media and imitation of others. Curiosity was a reason for having tried smoking and parents was perceived to be the first source for smoking. Religion was considered the main factor against smoking among the adolescent non-smokers and health consideration among college students.
