Exposure to Multimedia Tobacco Marketing and Product Use Among Youth: A Longitudinal Analysis.

Tobacco companies continue to reach youth through direct-to-consumer marketing, which has been associated with overall tobacco use. We examine how exposure to these marketing activities influences product-specific use behaviors. We analyzed data from 10 081 youth (aged 12-18 years) who participated in Waves 1 and 2 (2013-2015) of the Population Assessment of Tobacco and Health (PATH) Study. Participants reported past 6-month tobacco coupon receipt and online tobacco marketing engagement, and susceptibility to ever and current use of cigarette, e-cigarettes, cigars, smokeless tobacco, and hookah. Weighted multivariable logistic regression examined Wave 1 predictors of coupon receipt at Wave 2, and associations between coupon receipt, online engagement, and past 30-day use of different tobacco products. Youth received tobacco coupons at one (9.7%) or both waves (1.2%) and 11.1% engaged with online tobacco marketing. Coupon receipt and online marketing engagement at Wave 1 predicted Wave 2 coupon receipt among susceptible-never, ever-but-not-current, and current tobacco users (p < .05). Coupon receipt and online engagement at Wave 1 was positively associated with past 30-day use of cigarettes, e-cigarettes, cigars, smokeless tobacco, and hookah at Wave 2 (p < .05). The relationships were stronger for those who received coupons at both waves or engaged with more sources of online marketing. Tobacco direct-to-consumer marketing is reaching youth. Repeated exposure to these marketing activities within and across media is associated with use of different tobacco products. New policies and strong enforcement of existing regulations prohibiting these illegal marketing tactics are critical to protect youth from future tobacco use. Tobacco companies utilize coupons and online engagement activities to increase brand awareness, knowledge, and sales of their products. These kinds of marketing activities can be influential among youth at a time when they may develop tobacco use behaviors. Our findings suggest that tobacco companies may be targeting at-risk youth through cross-media marketing activities. The findings also indicate that exposure to these marketing activities predicts subsequent use of different tobacco products, with suggestive dose-response relationships. Increased regulations are needed to protect youth from these marketing activities.

Cannabis use among a nationally representative cross-sectional sample of smokers and non-smokers in the Netherlands: results from the 2015 ITC Netherlands Gold Magic Survey

ObjectivesExisting evidence shows that co-occurring use of tobacco and cannabis is widespread. Patterns of co-use of tobacco and cannabis may change as more jurisdictions legalise medicinal and/or recreational cannabis sales....

Is susceptibility to E-cigarettes among youth associated with tobacco and other substance use behaviors one year later? Results from the PATH study

E-cigarettes are the most commonly used tobacco product among youth. In addition to harm potential, e-cigarette use is associated with initiating cigarette smoking. Limited research exists whether susceptibility to e-cigarette use is a risk factor for future tobacco and other substance use initiation. This study examined associations between baseline e-cigarette susceptibility and initiation and past 30-day use of e-cigarettes and cigarettes as well as initiation of marijuana and alcohol one year later, after adjusting for other risk factors and sociodemographic confounders. The study sample consisted of 5156 nationally representative youth (12–17 years) who completed both waves 1 (2013–2014) and 2 (2014–2015) of the Population Assessment of Tobacco and Health (PATH) study and were never users of tobacco, marijuana, and alcohol in Wave 1. Youth who were susceptible to e-cigarettes had increased odds of initiating e-cigarettes (adjusted OR: 2.22, 95% CI: 1.55–3.18), marijuana (aOR: 1.66, 95% CI: 1.12–2.46), and alcohol (aOR: 1.61, 95% CI: 1.26–2.06) between waves, as well as past reporting 30-day e-cigarette use (aOR: 3.64, 95% CI: 1.93–6.89) in Wave 2. Additionally, cigarette susceptibility, but not e-cigarette susceptibility, was associated with cigarette initiation (aOR: 3.36, 95% CI: 1.95–5.82) and past 30-day use (aOR: 2.83, 95% CI: 1.34–5.97). Prevention policies, as well as future research, could target youth susceptible to e-cigarettes to reduce the current trends on the use of these alternative tobacco products. Such efforts may also reduce the use of cigarettes and other substances.

Trends in the use of cigarettes, cigars, and marijuana among students with and without asthma, 2003–2017

Aim: Asthma has symptoms that can be exacerbated by using combustible products such as tobacco and marijuana. This study assessed the prevalence and trends in current use of cigarettes, cigars, and marijuana among U.S. high school students with and without asthma. Methods: The national Youth Risk Behavior Survey (YRBS) is a biennial, school-based, nationally representative survey of U.S. students in grades 9–12. Trends during 2003–2017 in current (past 30-day) use of cigarettes, cigars, and marijuana among students with and without asthma were examined using logistic regression. Asthma was defined as reporting that a doctor or nurse ever told the student they had asthma. T-tests were used to compare cigarette, cigar, and marijuana use by asthma status and year, frequency of use, and student characteristics. Results: During 2003–2017, both current cigarette and cigar smoking decreased (p < 0.05) with rates that were similar among students with and without asthma. There was no significant linear change in current marijuana use, irrespective of asthma status. During most years, cigarette, cigar, and marijuana use were more common among students with asthma than without. In 2017, the most frequent use of cigarettes, cigars, and marijuana was among those with asthma than without. Differences in cigarette, cigar, and marijuana use by asthma status were apparent by demographic subgroups. Conclusions: Given the adverse respiratory effects of tobacco and marijuana smoking, efforts to educate all youth about the dangers of using these substances is critical, particularly among those with asthma.

Tobacco Retail Licensing and Youth Product Use.

Restricting youth access to tobacco is a central feature of US tobacco regulatory policy, but impact of local tobacco retail licensing (TRL) regulation on cigarette smoking rates remains uncertain. Effects of TRL on other tobacco product use and use as adolescents reach the age to legally purchase tobacco products has not been investigated. Prevalences of ever and past 30-day cigarette, electronic cigarette (e-cigarette), cigar, and hookah use were assessed in a survey of a cohort of 1553 11th- and 12th-grade adolescents (mean age: 17.3 years); rates of initiation were evaluated 1.5 years later. An American Lung Association (2014) youth access grade was assigned to each of 14 political jurisdictions in which participants lived on the basis of the strength of the local TRL ordinance. At baseline, participants living in 4 jurisdictions with "A" grades (ie, with most restrictive ordinances) had lower odds of ever cigarette use (odds ratio [OR] 0.61; 95% confidence interval [CI] 0.41-0.90) and of past 30-day use (OR 0.51; 95% CI 0.29-0.89) than participants in 10 D- to F-grade jurisdictions. At follow-up at legal age of purchase, lower odds of cigarette use initiation (OR 0.67; 95% CI 0.45-0.99) occurred in jurisdictions with stronger TRL policy. Lower odds of e-cigarette initiation at follow-up (OR 0.74; 95% CI 0.55-0.99) and of initiation with past 30-day use (OR 0.45; 95% CI 0.23-0.90) were also associated with better regulation. Strong local TRL ordinance may lower rates of cigarette and e-cigarette use among youth and young adults.

Young adults report increased pleasure from using e-cigarettes and smoking tobacco cigarettes when drinking alcohol

BackgroundCigarettes share a high rate of co-use with alcohol, particularly among young adults. Studies have demonstrated greater perceived pleasure from smoking cigarettes when drinking alcohol. However, little is known about co-use of electronic cigarettes (e-cigs) and alcohol. The current study sought to compare extent of use and perceived pleasure from cigarettes and e-cigs when drinking alcohol. MethodsYoung adult bar patrons in California cities (San Diego, Los Angeles, and San Francisco) were recruited in 2015–16 using randomized time-location sampling. Participants completed cross-sectional surveys in bars, reporting the percent of cigarette smoking/e-cig use that occurred under the influence of alcohol, and reported if pleasure from smoking cigarettes/using e-cigs changed when drinking alcohol. Analyses are limited to participants reporting current (past 30-day) use of cigarettes, e-cigs, and alcohol (N = 269; M age = 24.1; 40.1% female, 36.1% Non-Hispanic White). ResultsParticipants reported a greater percentage of cigarette smoking compared to e-cig use under the influence of alcohol (cigarettes M = 63.6%; e-cigs M = 46.7%; p < .001). Participants also reported increased pleasure both from smoking cigarettes (M = 3.9; [compared to midpoint of scale 3 - “no change”] p < .001) and using e-cigs (M = 3.3; p < .001) when drinking alcohol. The increase in pleasure was more pronounced for cigarettes compared to e-cigs (p < .001). ConclusionsDrinking alcohol is associated with increases in perceived rewarding effects of both cigarettes and e-cigs and thus may increase their abuse liability. This effect may be stronger for cigarettes, which could be an important barrier to switching completely from smoking cigarettes to using e-cigs, or quitting both entirely.

Disaggregating Asian American and Native Hawaiian and Other Pacific Islander (AANHOPI) Adult Tobacco Use: Findings from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study, 2013-2014.

Tobacco studies often combine data for Asian American and Native Hawaiian and Other Pacific Islander (AANHOPI) subgroups, masking subgroup differences. This study describes tobacco use (ever use and past 30-day use) among some disaggregated AANHOPI subgroups. Data are from Wave 1 of the 2013-2014 Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal cohort study of civilian non-institutionalized adults and youth in the USA. The dataset contains a sample of 32,320 adults, of which 1623 identified as being of AANHOPI origin. Asian Americans further identified as being Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, or other Asian. Those who identified as Native Hawaiian, Guamanian or Chamarro, Samoan, and Other Pacific Islander were combined into an NHOPI group. Tobacco measures included ever and past 30-day use of cigarettes, e-cigarettes, cigars (traditional cigar, cigarillos, filtered cigar), hookah, and smokeless tobacco including snus pouches, and pipe tobacco. Unadjusted and adjusted estimates for tobacco use are reported by AANHOPI membership and sex. In general, Asian Indians and Chinese had the lowest and NHOPI had the highest tobacco use prevalence compared to other AANHOPI subgroups. Males generally had higher prevalence compared to females. Prevalence varied by AANHOPI membership and tobacco product. Adjusted prevalence estimates were higher compared to unadjusted estimates for many subgroups, attenuating some unadjusted differences found between AANHOPI subgroups. Tobacco use varies by AANHOPI subgroup and product type. Unadjusted and adjusted analyses can be conducted as tobacco use differences in AANHOPI subgroups may be attributed to socio-economic status differences. Treating these distinct subgroups as a monolithic group may contribute to reliance on tobacco prevention and control strategies that may have limited impact on specific subgroups.

Using a Smoking Cessation Quitline to Promote Lung Cancer Screening

Objective We assessed whether in-depth messaging delivered via a smoking cessation quitline results in participants: (1) speaking to their physician, or (2) insurance company regarding lung cancer screening (LCS). MethodsEligible participants lived in New York State and met the United States Preventive Services Task Force eligibility criteria for LCS (N = 1000). A randomized trial was conducted among New York State Smokers' Quitline participants to assess the impact of a brochure containing information on risks, benefits, and costs associated with LCS (control group) versus the brochure supplemented with phone-based in-depth messaging (treatment group). ResultsAfter a 4-month telephone survey (N = 431), associations between the study groups were examined for: (1) speaking with a physician regarding LCS, and (2) speaking with an insurance company about LCS coverage. Multivariate logistic regression models adjusted for demographics, insurance status, emphysema/COPD, and past 30-day cigarette use found no significant associations. However, sensitivity analyses among control participants found significant associations, including for speaking with a physician (p < .05) by receipt of the study brochure. Analyses repeated in the treatment group also had statistically significant findings emerge, including for speaking with insurance company (p < .05). ConclusionsThe educational brochure may be an effective and low-cost way to deliver information about LCS.

Electronic cigarette marketing and smoking behaviour in adolescence: a cross-sectional study.

The aim of this study was to investigate the association between exposure to electronic cigarette (e-cigarette) advertisements and use of e-cigarettes, combustible cigarettes and hookahs.A cross-sectional survey of 6902 German students (mean age 13.1 years, 51.3% male) recruited in six German states was performed. Exposure to e-cigarette advertisements was measured with self-rated contact frequency to three advertising images. Multilevel mixed-effect logistic regression models were used to assess associations between exposure to e-cigarette advertisement and use of e-cigarettes, combustible cigarettes and hookahs (ever and past 30 days).Overall, 38.8% of the students were exposed to e-cigarette advertisements; ever-use of e-cigarettes was 21.7%, of combustible cigarettes was 21.8% and of hookahs was 23.2%, and poly-use of all three products was 12.4%. Exposure to e-cigarette advertisements was positively related to ever and past 30-day use of e-cigarettes, combustible cigarettes, hookahs and combined use.We concluded that a considerable number of German teenagers are exposed to e-cigarette advertisement. There was a clear exposure–behaviour link, indicating that advertising contact was associated with different kinds of “vaping” and also smoking behaviour. Although causal interpretation is not possible due to the cross-sectional design, findings raise concerns about the current tobacco control policies.

Tobacco Advertisement Liking, Vulnerability Factors, and Tobacco Use Among Young Adults.

Young adulthood (aged 18-24) is a crucial period in the development of long-term tobacco use patterns. Tobacco advertising and promotion lead to the initiation and continuation of smoking among young adults. We examined whether vulnerability factors moderated the association between tobacco advertisement liking and tobacco use in the United States. Analyses were conducted among 9109 US young adults in the nationally representative Population Assessment of Tobacco and Health (PATH) Study wave 1 (2013-14). Participants viewed 20 randomly selected sets of tobacco advertisements (five each for cigarettes, e-cigarettes, cigars, and smokeless tobacco) and indicated whether they liked each ad. The outcome variables were past 30-day cigarette, e-cigarette, cigar, and smokeless tobacco use. Covariates included tobacco advertisement liking, age, sex, race or ethnicity, sexual orientation, education, poverty level, military service, and internalizing and externalizing mental health symptoms. Liking tobacco advertisements was associated with tobacco use, and this association was particularly strong among those with lower educational attainment (cigarettes, cigars) and living below the poverty level (e-cigarettes, smokeless tobacco). The association between tobacco advertisement liking and tobacco use was stronger among young adults with lower educational attainment and those living below the poverty level. Policies that restrict advertising exposure and promote counter-marketing messages in this population could reduce their risk. This study shows that liking tobacco advertisements is associated with current tobacco use among young adults, with stronger associations for vulnerable young adults (ie, lower education levels and living below the poverty level). Findings suggest a need for counter-marketing messages, policies that restrict advertising exposure, and educational interventions such as health and media literacy interventions to address the negative influences of tobacco advertisements, especially among young adults with a high school education or less and those living below the poverty level.

Perceived family relationship quality and use of poly-tobacco products during early and late adolescence

BackgroundThe role of family relationship in adolescent use of emerging tobacco products, which have become increasingly popular, is unknown. We examined the associations of perceived family relationship quality with current use of poly-tobacco products including cigarettes, electronic cigarettes (e-cigarettes), waterpipe and smokeless tobacco in adolescents. MethodsData from a representative sample of 42,250 US grade 7–12 equivalent students (mean ± SD age 14.6 ± 1.9 years; 51.3% boys) from 75 randomly selected secondary schools in Hong Kong (2012−13) were analysed. Logistic regressions yielded adjusted odds ratios (AORs) for current (past 30-day) use of cigarettes, e-cigarettes, waterpipe, smokeless tobacco and poly-tobacco (≥2 products) in relation to perceived family relationship quality, adjusted for age, sex, perceived family affluence, parental education, family structure, parental and sibling smoking and secondhand smoke exposure at home. Subgroup analyses were conducted to compare the associations in early (aged ≤14 years) versus late (>14) adolescents. ResultsThe odds of current use increased with worse perceived family relationship quality with AORs (95% confidence interval) of up to 2.92 (2.32–3.68) for cigarettes, 7.28 (4.71–11.2) for e-cigarettes, 5.04 (3.44–7.40) for waterpipe, 8.09 (4.87–13.4) for smokeless tobacco and 5.25 (3.45–8.01) for poly-tobacco products use (all P for trend <.001). The associations for all tobacco use outcomes were stronger in early than late adolescents (all P for interaction <.001). ConclusionsDose-response relationships were found between negatively perceived family relationship quality and current poly- and individual tobacco product use by Hong Kong Chinese secondary students. The associations were stronger for alternative tobacco products and in early adolescents.

An Algorithm for Creating Virtual Controls Using Integrated and Harmonized Longitudinal Data.

We introduce a strategy for creating virtual control groups-cases generated through computer algorithms that, when aggregated, may serve as experimental comparators where live controls are difficult to recruit, such as when programs are widely disseminated and randomization is not feasible. We integrated and harmonized data from eight archived longitudinal adolescent-focused data sets spanning the decades from 1980 to 2010. Collectively, these studies examined numerous psychosocial variables and assessed past 30-day alcohol, cigarette, and marijuana use. Additional treatment and control group data from two archived randomized control trials were used to test the virtual control algorithm. Both randomized controlled trials (RCTs) assessed intentions, normative beliefs, and values as well as past 30-day alcohol, cigarette, and marijuana use. We developed an algorithm that used percentile scores from the integrated data set to create age- and gender-specific latent psychosocial scores. The algorithm matched treatment case observed psychosocial scores at pretest to create a virtual control case that figuratively "matured" based on age-related changes, holding the virtual case's percentile constant. Virtual controls matched treatment case occurrence, eliminating differential attrition as a threat to validity. Virtual case substance use was estimated from the virtual case's latent psychosocial score using logistic regression coefficients derived from analyzing the treatment group. Averaging across virtual cases created group estimates of prevalence. Two criteria were established to evaluate the adequacy of virtual control cases: (1) virtual control group pretest drug prevalence rates should match those of the treatment group and (2) virtual control group patterns of drug prevalence over time should match live controls. The algorithm successfully matched pretest prevalence for both RCTs. Increases in prevalence were observed, although there were discrepancies between live and virtual control outcomes. This study provides an initial framework for creating virtual controls using a step-by-step procedure that can now be revised and validated using other prevention trial data.

Sex and orientation identity matter in the substance use behaviors of sexual minority adolescents in the United States

BackgroundHealth sciences researchers are beginning to understand the differing experiences and health risks among sexual minority subgroups (i.e., those who describe themselves as homosexual/gay/lesbian, bisexual, or unsure/questioning). Such research can promote the allocation of resources to high-risk groups and the development of interventions tailored to their needs. The present study extends this line of research to substance use among adolescents. MethodsThe lifetime and/or past 30-day alcohol, tobacco, cigarette, e-cigarette, marijuana, prescription drug, and illicit drug use of sexual minority and heterosexual adolescents was analyzed using data from the 2015 National Youth Risk Behavior Survey. Controlling for confounders, separate logistic regression models were fit for each substance use outcome. A simulation-based strategy was employed to report adjusted risk ratios for each substance use outcome for each sexual minority subgroup. ResultsSexual minority females, particularly bisexual females, were at an elevated risk for substance use. For example, compared to heterosexual females, sexual minority females were 1.35 (95%CI 1.16–1.56) times more likely to have used a substance in the past 30 days, and bisexual females had an even further elevated risk ratio (RR: 1.48, 95%CI 1.28–1.69). ConclusionsStudying the variance among sexual minority subgroups will help practitioners, advocates, and policymakers identify high risk subgroups. In the case of substance use, this study suggests sexual minority females, particularly bisexual females, should become a target population for prevention and other interventions. The study conducts post-hoc analyses on secondary data, and so these results should be verified in more targeted studies.

Perceived racial/ethnic discrimination, marketing, and substance use among young adults

ABSTRACTPerceived experiences of discrimination have been linked to negative health behaviors including tobacco, alcohol, and marijuana use across various racial/ethnic groups. Tobacco and alcohol marketing exposure have also been linked with substance use. This study examined the independent and interacting effects of perceived experiences of discrimination and exposure to alcohol and tobacco marketing, and receptivity to marijuana marketing on substance use in an online survey of a multiethnic sample of young adults in 6 metropolitan areas (n = 505). African Americans (mean (M) = 1.96, 9% 5CI [1.84, 2.09]) and Hispanics (M = 1.98, 95% CI [1.87, 2.09]) reported higher levels of perceived discrimination than Whites (M = 1.52, 95% CI [1.40, 1.64]), p < .001. African Americans had higher levels of exposure to tobacco and alcohol marketing; Hispanics reported higher levels of exposure to alcohol marketing and receptivity to marijuana promotion. Discrimination and marketing exposure were independently associated with higher odds of all 3 outcomes, controlling for covariates (AOR from 2.1 to 3.4 for discrimination; AOR from 1.4 to 13.8 for marketing). Models showed a significant interaction of discrimination and tobacco marketing on past 30-day cigarette use (F = 5.5; p = .02). Individuals with high levels of tobacco marketing exposure were likely to report high past 30-day cigarette use regardless of level of discrimination, while those with low exposure were only at increased risk of reporting cigarette use at higher levels of discrimination. Both perceived discrimination and marketing exposure play a role in substance use. Interventions should consider discrimination as a significant risk factor underlying vulnerability to substance use among young adults.

Tobacco Use Among Middle and High School Students in Pennsylvania.

We analyzed data from the 2014–2015 Pennsylvania Youth Tobacco Survey to determine prevalence of tobacco use among middle and high school students. For the first time, questions on current (past 30-day) use of electronic cigarettes (e-cigarettes) were included in the survey. For current use, e-cigarettes were the most commonly used tobacco product among middle school students (2.3%; 95% confidence interval [CI], 1.4%–3.2%), and cigarettes were the most commonly used tobacco product among high school students (11.0%; 95% CI, 8.1%–13.8%). Given the changing landscape of tobacco products, collection of comprehensive data on tobacco use, including frequency, is important for monitoring behaviors among adolescents.

Tobacco harm perceptions and use among sexual and gender minorities: findings from a national sample of young adults in the United States

IntroductionIn the United States, the prevalence of tobacco use among sexual and gender minorities (SGM) is higher compared to their non-SGM counterparts. Tobacco harm perceptions have gone largely unexamined as a potential mechanism supporting disproportionate tobacco use among this population. The purpose of this study was to examine differences between SGM and non-SGM young adults in harm perceptions of various tobacco products and tobacco use behavior and whether low tobacco-related harm perceptions moderate the relationship between identifying as a SGM and tobacco use behavior. MethodsThis study used data from Wave 10 of the Truth Initiative Young Adult Cohort Study, a sample of U.S. young adults (ages 18–34). Data were collected from September to October 2016 and the study sample included 3089 individuals. Demographics, past 30-day use of cigarettes, little cigars/cigarillos/bidis and electronic cigarettes were assessed. Absolute and relative harm perceptions of these products were also examined. ResultsIdentifying as a SGM and low tobacco harm perceptions were found to be positively associated with past 30-day tobacco use. There was no interaction between SGM status and harm perceptions on past 30-day tobacco use ConclusionsFindings confirm that SGM young adults continue to disproportionately use tobacco products, compared to non-SGM young adults. More research is needed to understand moderators of the relationship between SGM status and tobacco use in young adults.

Prevalence of Substance Use among Lesbian, Gay, Bisexual, and Transgender Youth in Military Families: Findings from the California Healthy Kids Survey

ABSTRACTBackground: In addition to the challenges associated with military life, lesbian, gay, bisexual, and transgender (LGBT) youth in military families may face stressors associated with having a stigmatized sexual orientation and/or gender identity or expression, placing them at risk of substance use. To the authors' knowledge, this is the first study exploring substance use outcomes among LGBT youth in military families. Objectives: This study assessed the role of military connection, LGB identity, and transgender identity on lifetime and past 30-day substance use. Methods: This study is a secondary data analysis of the 2013–2015 California Healthy Kids Survey (CHKS). The study's participants (n = 634,978) were students attending middle and high schools in nearly all school districts in California. The study outcomes were lifetime and past 30-day cigarette, alcohol, tobacco, and marijuana use. Chi-square tests of associations (including cross-tabulations) and multivariate logistic regressions were conducted to address the study aims. Results: Multivariate logistic regression results indicated that military connection, LGB identity, and transgender identity were significantly associated with an increased odd of lifetime and past 30-day substance use. Compared to military non-transgender youth, military transgender youth had an increased likelihood of past 30-day cigarette use and past 30-day alcohol use. In addition, military LGB youth were 3.62 times as likely as military non-LGB youth to report past 30-day cigarette use. Conclusions/Importance: This study provides researchers with knowledge about the behavioral health of LGBT youth in military families, a vulnerable subgroup within the military-connected youth population, thus informing substance use prevention programs.

Association of Noncigarette Tobacco Product Use With Future Cigarette Smoking Among Youth in the Population Assessment of Tobacco and Health (PATH) Study, 2013-2015

Approximately 90% of adult smokers first tried a cigarette by 18 years of age, and even infrequent smoking in adolescence is associated with established adult smoking. Noncigarette tobacco use is increasing and could stimulate subsequent conventional cigarette smoking in youths. To estimate the longitudinal association between noncigarette tobacco use and subsequent cigarette smoking initiation among US youth. In this prospective cohort study of the Population Assessment of Tobacco and Health (PATH) waves 1 (September 12, 2013, to December 14, 2014) and 2 (October 23, 2014, to October 30, 2015), a nationally representative sample of youths who never smoked a conventional cigarette at baseline and completed wave 2 follow-up (N = 10 384) was studied. PATH retention at follow-up was 87.9%. Ever use and past 30-day use of electronic cigarettes (e-cigarettes), hookah, noncigarette combustible tobacco, or smokeless tobacco at baseline. Ever use and past 30-day use of cigarettes at follow-up. The present analysis was based on the 10 384 PATH youth respondents who reported never having smoked a cigarette in wave 1 and whose cigarette ever or past 30-day use was reported in wave 2 (mean [SD] age, 14.3 [1.7] years; age range, 12-17 years; 5087 [49.1%] female; 4829 [52.5%] white). At 1-year follow-up, 469 (4.6%) of all baseline never-smoking youths had tried a cigarette and 219 (2.1%) had smoked a cigarette within the past 30 days. Cigarette ever use at follow-up was higher among youths who had ever used e-cigarettes (78 [19.1%]), hookah (60 [18.3%]), noncigarette combustible tobacco (45 [19.2%]), or smokeless tobacco (29 [18.8%]) at baseline. After adjusting for sociodemographic, environmental, and behavioral smoking risk factors and for baseline ever use of other tobacco products, the odds of past 30-day cigarette use at follow-up were approximately twice as high among baseline ever users of e-cigarettes (odds ratio [OR], 1.87; 95% CI, 1.15-3.05), hookah (OR, 1.92; 95% CI, 1.17-3.17), noncigarette combustible tobacco (OR, 1.78; 95% CI, 1.00-3.19), and smokeless tobacco (OR, 2.07; 95% CI, 1.10-3.87). Youths who had tried more than 1 type of tobacco product at baseline had 3.81 (95% CI, 2.22-6.54) greater adjusted odds of past 30-day cigarette smoking at follow-up than did baseline never tobacco users. Any use of e-cigarettes, hookah, noncigarette combustible tobacco, or smokeless tobacco was independently associated with cigarette smoking 1 year later. Use of more than 1 product increased the odds of progressing to cigarette use.

Weight Status and Cigarette and Electronic Cigarette Use in Adolescents.

Research shows that adolescents who are overweight or obese may be at greater risk of cigarette smoking, and that this relationship may vary by gender. However, this relationship is understudied for electronic cigarettes (e-cigarettes). Given the high rate of adolescent obesity and the rise in e-cigarette use in adolescents, this relationship should be investigated. Data are from the third wave (collected October 2015-January 2016) of the Texas Adolescent Tobacco and Marketing Surveillance system. Students were in the seventh, ninth, and 11th grades (n=2,733) from five counties surrounding four major Texas metropolitan areas (Houston, Austin, San Antonio, Dallas). Weighted logistic regression was used to determine if weight status (healthy weight, overweight, or obese) was correlated with ever and past 30-day cigarette or e-cigarette use, controlling for sociodemographics. Models were stratified by gender. Data analyses were conducted in March 2017. Compared with healthy-weight boys, obese boys had higher odds of past 30-day e-cigarette use (AOR=3.45, 95% CI=1.34, 8.33) and cigarette smoking (AOR=4.52, 95% CI=1.32, 15.51). There was no significant relationship between weight status and cigarette or e-cigarette use in girls. This study supports that there is a positive relationship between weight status and past 30-day cigarette and e-cigarette use for boys, but that there is no association for girls.

Mobile Technology for Treatment Augmentation in Veteran Smokers With Posttraumatic Stress Disorder

The purpose of this study is to examine the feasibility and acceptability of incorporating a mobile application, Stay Quit Coach, into an integrated care smoking-cessation treatment protocol for veterans with posttraumatic stress disorder (PTSD). Participants included veteran smokers aged 18-69 years with PTSD. The integrated care protocol includes eight weekly PTSD-informed cognitive behavioral therapy sessions for smoking cessation, followed by monthly booster sessions and a prescription for standard smoking-cessation medications if desired. Participants used Stay Quit Coach as desired. Outcome measures at 3-month follow-up included: adherence (sessions attended), 30-day point-prevalence abstinence bioverified with carbon monoxide <6 parts per million, past-30 day mean daily cigarette use, exhaled carbon monoxide, nicotine dependence, and PTSD symptom severity. Repeated outcomes were analyzed with random-intercept linear mixed models. Data were collected in 2015-2016 and analyses were conducted in 2016-2017. Participants (n=20) were 95% male and 5% female; mean age 41.4 (SD=16.2) years. Thirteen participants (65%) attended all scheduled sessions, four (20%) did not adhere to the protocol on schedule, and three (15%) were lost to follow-up. At 3-month follow-up, six of 17 completers (35.3%) had bioverified 30-day point-prevalence abstinence. Nicotine dependence, carbon monoxide levels, and past 30-day cigarette use significantly decreased and PTSD symptoms were unchanged from baseline to follow-up. Participants self-reported using Stay Quit Coach 2.5 (SD=2.2) days/week; 15 of 17 (88.2%) reported using Stay Quit Coach <30 minutes/week; two of 17 (11.8%) reported using Stay Quit Coach 30-60 minutes/week. Although results must be interpreted with caution given the lack of control group and small sample size, findings indicate that integrating Stay Quit Coach into integrated care was feasible and acceptable.
