Use of these products among young adults is of particular interest given that experimentation with new products is common in young adulthood. METHODS: We conducted latent class analysis among a population-based sample of young adults to identify separate classes based on use of 6 types of tobacco or nicotine products: snus, hookah, electronic cigarettes, cigarillos, snuff, and cigarettes. We then examined how identified classes differed on demographic characteristics and marijuana and alcohol use. RESULTS: We identified 5 classes: the largest group (60%) was characterized as reporting no or limited use of any of the products, while the smallest group (7%) was characterized by use of many types of products (poly-users). Of the 3 middle classes, 2 were the same size (10%) and were characterized by primarily using 2 of the products: one class used snus and snuff, and the other used cigarillos and hookah; the third class (13%) was characterized by primarily cigarette smoking. Numerous differences were seen across classes, including the poly-users being less likely to be college students/graduates and more likely to be male and use marijuana and alcohol. CONCLUSIONS: We found that young adults can be grouped into 5 subgroups based on types of tobacco/nicotine products they do and do not use. A poly-use group that uses all types of tobacco products is concerning, particularly given high levels of marijuana and alcohol use reported in this group.

Data were derived from a cross-sectional survey of students enrolled in the 6th and 8th grades in 32 schools in Delhi and Chennai (N = 11,642). The survey was conducted in 2004, before the implementation of a program designed to prevent and reduce tobacco use (MYTRI). Mixed-effect regression models were used (a) to determine the prevalence of tobacco use among private (higher SES) and government (lower SES) school students, (b) to investigate whether certain psychosocial factors were associated with increased tobacco use, and (c) to determine how these factors varied by school type. Ever-use of multiple forms of tobacco (e.g., gutkha, bidis, and cigarettes) was more prevalent among government school students than private school students. After adjusting for city, gender, grade, and age, we found the prevalence rate for ever-use of any tobacco product to be 18.9% for government school students, compared with 12.2% for private school students (p<.01). Students in government schools scored lower than private school students on most psychosocial risk factors for tobacco use studied here, indicating higher risk. Government school students scored the lowest for refusal skills, self-efficacy, and reasons not to use tobacco. Social susceptibility to chewing tobacco and social susceptibility to smoking were strong correlates of current tobacco use among government school students. Exposure to tobacco advertising was also a strong correlate of current tobacco use for government school students but not private school students. In two large cities of India, students attending government schools are using many forms of tobacco at higher rates than private school students. The psychosocial risk profile of government school students suggests they are more vulnerable to initiation and use and to outside influences that encourage use.

Scholars have suggested that smokers may see cigarette tax increases as commitment devices to help them quit smoking. Little is known about whether smokers actually think cigarette tax increases help them quit, and whether this perception predicts subsequent smoking cessation behaviors. We used data from the Minnesota Adult Tobacco Survey Cohort Study collected after the 2009 federal tobacco tax increase to answer these questions. METHODS: In 2009, 727 smokers were asked whether they thought the federal tobacco tax increase helped them to: (1) think about quitting, (2) cut down on cigarettes, and (3) make a quit attempt. We also collected data on demographics, number of cigarette price-minimizing strategies used, and cigarette consumption. In 2010, we assessed if these smokers had made a quit attempt, had cut down on their cigarette consumption, and had stopped smoking. Logistic regression models were used to assess the characteristics associated with the perceptions that the tax increase was helpful in assisting smoking cessation, and the association between these perceptions in 2009 and cessation behaviors in 2010. RESULTS: Overall, 65% of the sample thought that the 2009 tax increase helped them think about quitting, 47% thought it helped them cut down on cigarettes, and 29% thought it helped them make a quit attempt. Lower education, lower income, lower cigarette consumption, and using more cigarette price-minimizing strategies were associated with the perceptions that the tax increase was helpful in assisting smoking cessation (p Descriptors Links Book Title Database Publisher Data Source Authors Choi,K., Boyle,R.G.

However, little is known about the awareness, perceptions and use of snus among young adults after Camel and Marlboro snus were sold nationwide in 2010. METHODS: Data were collected from 2607 young adults (ages 20-28) who participated in the Minnesota Adolescent Community Cohort Study in 2010-2011. Data include awareness of snus, ever and past 30-day use, perceived potential of snus as a quit aid, and perceived harmfulness and addictiveness of snus relative to cigarettes. The authors assessed the associations between these outcome variables and socio-demographic characteristics. RESULTS: Overall, 64.8% of participants were aware of snus, 14.5% ever used snus and 3.2% used snus in the past 30 days. Men and participants who smoked >100 cigarettes in their lifetime were associated with these three outcomes (p Descriptors Links Book Title Database Publisher Data Source Authors Choi,K., Forster,J.

METHODS: We collected data in 2010-2011 from a cohort of 2624 US Midwestern adults aged 20 to 28 years. We assessed awareness and use of e-cigarettes, perceptions of them as a smoking cessation aid, and beliefs about their harmfulness and addictiveness relative to cigarettes and estimated their associations with demographic characteristics, smoking status, and peer smoking. RESULTS: Overall, 69.9% of respondents were aware of e-cigarettes, 7.0% had ever used e-cigarettes, and 1.2% had used e-cigarettes in the past 30 days. Men, current and former smokers, and participants who had at least 1 close friend who smoked were more likely to be aware of and to have used e-cigarettes. Among those who were aware of e-cigarettes, 44.5% agreed e-cigarettes can help people quit smoking, 52.8% agreed e-cigarettes are less harmful than cigarettes, and 26.3% agreed e-cigarettes are less addictive than cigarettes. CONCLUSIONS: Health communication interventions to provide correct information about e-cigarettes and regulation of e-cigarette marketing may be effective in reducing young adults' experimentation with e-cigarettes.

Preventing tobacco experimentation and uptake among young people in LMICs is therefore vital. However, data on smoking in these countries, particularly in sub-Saharan Africa, remain sparse. Method: We used two-stage cluster random sampling to select students in upper and senior secondary schools throughout The Gambia, and a self-administered questionnaire to collect data on their tobacco use, risk factors and demographic details. Results: Of 10 392 eligible students, 10 289 (99%; 55% girls and 44% boys, age 12-20 years) participated. The prevalence of ever smoking cigarettes, cigars or pipes was 16.7% (25.7% boys and 9.4% girls) and current (past 30 days) smoking 4.5% (7.9% boys and 1.5% girls). Smoking was more common among students attending private schools (OR 1.69, 95% CI 1.29 to 2.22), of Christian or other faiths compared with Muslims, living with parents (OR 1.39, 95% CI 1.06 to 1.81), who had smoking allowed in their homes (OR 1.67, 95% CI 1.30 to 2.13), with family members who smoked or had one or more friends who smoked. Most (55.6%) smokers want to stop, but only 22% received any stop smoking support. Ever smoking of shisha, at 8.1%, was unexpectedly high, and relatively prevalent among girls (11.4% of boys and 5.4% of girls). Conclusions: Tobacco use is common among young people in The Gambia. Shisha smoking is also common in this population, and in relative terms especially among girls. Further work is required to determine whether this is a problem local to The Gambia or reflects a wider pattern of tobacco use in sub-Saharan Africa.

Substantial growth in the prospective cohort study evidence base provides an opportunity to generate new and more detailed estimates of the magnitude of the effect. A systematic review and meta-analysis was conducted to provide estimates of the prospective effect of smoking by parents or household members on the risk of wheeze and asthma at different stages of childhood. METHODS: We systematically searched Medline, Embase, and conference abstracts to identify cohort studies of the incidence of asthma or wheeze in relation to exposure to prenatal or postnatal maternal, paternal, or household smoking in subjects aged up to 18 years old. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated by using random effects model. RESULTS: We identified 79 prospective studies. Exposure to pre- or postnatal passive smoke exposure was associated with a 30% to 70% increased risk of incident wheezing (strongest effect from postnatal maternal smoking on wheeze in children aged =2 years, OR = 1.70, 95% CI = 1.24-2.35, 4 studies) and a 21% to 85% increase in incident asthma (strongest effect from prenatal maternal smoking on asthma in children aged =2 years, OR = 1.85, 95% CI = 1.35-2.53, 5 studies). CONCLUSIONS: Building upon previous findings, exposure to passive smoking increases the incidence of wheeze and asthma in children and young people by at least 20%. Preventing parental smoking is crucially important to the prevention of asthma.

However, there have been no studies assessing the association between environmental levels of hazardous air pollutants, such as benzene, and neural tube defects (NTDs), a common and serious group of congenital malformations. OBJECTIVE: Our goal was to conduct a case-control study assessing the association between ambient air levels of benzene, toluene, ethylbenzene, and xylene (BTEX) and the prevalence of NTDs among offspring. METHODS: The Texas Birth Defects Registry provided data on NTD cases (spina bifida and anencephaly) delivered between 1999 and 2004. The control group was a random sample of unaffected live births, frequency matched to cases on year of birth. Census tract-level estimates of annual BTEX levels were obtained from the U.S. Environmental Protection Agency 1999 Assessment System for Population Exposure Nationwide. Restricted cubic splines were used in mixed-effects logistic regression models to determine associations between each pollutant and NTD phenotype. RESULTS: Mothers living in census tracts with the highest benzene levels were more likely to have offspring with spina bifida than were women living in census tracts with the lowest levels (odds ratio = 2.30; 95% confidence interval, 1.22-4.33). No significant associations were observed between anencephaly and benzene or between any of the NTD phenotypes and toluene, ethylbenzene, or xylene. CONCLUSION: In the first study to assess the relationship between environmental levels of BTEX and NTDs, we found an association between benzene and spina bifida. Our results contribute to the growing body of evidence regarding air pollutant exposure and adverse birth outcomes.

DESIGN: Prospective cohort study. SETTING: The Stockholm County of Sweden. SUBJECTS: 2232 adolescents recruited in the fifth grade (mean age 11.6 years) with follow up in the eighth grade. MAIN OUTCOME MEASURES: Self reported tobacco use (ever and current use of cigarettes and/or snus) in the eighth grade. RESULTS: Parents' tobacco use was associated with adolescents' current use of cigarettes and snus (odds ratio (OR) 2.7, 95% confidence interval (CI) 1.8 to 3.9 if both parents used tobacco v neither parent). Mother's cigarette smoking was associated with adolescents' current exclusive smoking (OR 2.4, 95% CI 1.6 to 3.6). Father's use of snus was associated with current exclusive use of snus among boys (OR 3.0, 95% CI 1.4 to 6.4), but not with current cigarette use. The overall prevalence of current smoking was lower among children whose fathers used snus than among those whose fathers smoked. CONCLUSIONS: Parental smoking, especially maternal smoking, enhances the risk of tobacco experimentation in youths, as does paternal use of smokeless tobacco. However, the transition to regular cigarette smoking is not likely to be affected by paternal use of smokeless tobacco. Contextual factors, in particular declining smoking trends and negative social acceptance of smoking, can explain most of these findings.
