BackgroundRecent years have seen a rapid increase in the popularity of electronic cigarettes (e-cigarettes) among adolescents in the USA. Evidence on their role in the continuation of or abstinence from cigarette smoking among young smokers remains scarce.ObjectiveTo examine the relationship between e-cigarette use initiated after cigarette smoking and abstinence from cigarette smoking among US adolescent established smokers.MethodsThe data were drawn from the 2015–2018 National Youth Tobacco Survey—a nationally representative survey of US middle and high school students. Multivariable logistic regression was used to assess the association between ever e-cigarette use and past 30-day abstinence from cigarette smoking. The analytical sample comprised ever established cigarette smokers with or without a history of e-cigarette use after smoking initiation.ResultsNeither experimental (adjusted OR 0.67, 95% CI 0.39–1.14) nor prior established (adjusted OR 1.56, 95% CI 0.96–2.56) nor current established (adjusted OR 0.65, 95% CI 0.41–1.03) e-cigarette use was statistically significantly associated with subsequent abstinence from cigarette smoking among adolescent ever established smokers. These findings were largely consistent across sensitivity analyses using alternative key definitions, although experimental and current established e-cigarette use was significantly negatively associated with past 6-month abstinence.ConclusionsWe found no evidence that e-cigarette use among US adolescents already smoking cigarettes is associated with subsequent abstinence from cigarette smoking; there was some evidence of an inverse association among experimental and current established e-cigarette users. These findings could inform future regulatory and public health efforts regarding youth e-cigarette use and the reduction of youth cigarette smoking in the USA.

Objective: US adolescents are exposed to high levels of advertisements for electronic cigarettes (e-cigarettes). This study aimed to examine the associations between exposure to e-cigarette advertisements and perception, interest, and use of e-cigarettes among US middle school and high school students. Methods: Data from the 2014 cross-sectional National Youth Tobacco Survey were used. Logistic regressions were conducted to model four outcomes, including perception of reduced harmfulness compared to regular cigarettes, perception of reduced addictiveness, intention to use, and current use of e-cigarettes. Main predictors were exposure to e-cigarette advertisements via four sources, including Internet, newspaper/magazines, retail stores, and TV. Results: When all the four sources of e-cigarette advertisements exposure were evaluated jointly, exposure via the Internet was associated with elevated likelihood of reporting all four outcomes related to e-cigarettes, while exposure via retail stores was associated with higher likelihood of current e-cigarette use and perception of reduced harmfulness of e-cigarettes compared to regular cigarettes ( p < .05). However, exposure via newspaper/magazines and TV was associated with lower likelihood of perceiving e-cigarettes to be less harmful or addictive ( p < .05). Conclusion: Exposure to e-cigarette advertisements via the Internet and retail stores may play a significant role in adolescents’ use and perception of e-cigarettes. The results call for more research on the influence of different sources of advertising exposure on e-cigarette use to help public health programmes curtail the fast growing use of e-cigarette products among youth.

IntroductionIn Taiwan, national tobacco use surveys show that e-cigarette use has increased since 2014 among youth, while, at the same time, conventional cigarette smoking has continuously decreased. The purpose of this study is to examine whether the increased popularity of e-cigarettes has undermined this favourable declining trend for cigarette smoking.MethodsWe examined conventional cigarette and e-cigarette prevalence among male high school students (aged 16–18 years) and adults from 2004 to 2017, using data from cross-sectional nationally representative surveys. Applying interrupted time series analysis, we assessed whether there was a change in trend in 2014, when e-cigarette use started to gain popularity from long-term trends in prior years (2004–2013).ResultsE-cigarette use prevalence increased from 2.5% in 2014 to 6.4% in 2017 among male high school students but was negligible among male adults, declining from 1.4% in 2015 to 0.8% in 2017. The annual relative decline in the cigarette smoking rate after e-cigarettes started to gain popularity was greater (−10%) than the long-term trend (−2%) among high school students. Among adults, the change in trend over time after e-cigarettes started to gain popularity was not significant (ie, not significantly different from 0).ConclusionsThe increased popularity of e-cigarettes since 2014 is associated with a greater decline in youth smoking, compared with previous years. On the contrary, e-cigarette use has remained very low among Taiwanese male adults and no additional impact on the conventional smoking trend is found.

BackgroundWhile much is known about the influence of tobacco control spending on the demand for conventional cigarettes, little is known about the effects of tobacco control spending on the demand for electronic cigarettes (e-cigarettes). This study provides the first evidence on the association between state tobacco control spending and high school student vaping in the USA.MethodsWe used data from the 2015 through 2019 National Youth Risk Behavior Surveys to estimate vaping prevalence and vaping intensity demand equations. We employed logistic regressions to estimate the vaping prevalence equations and generalised linear models with log-link and gamma distribution to estimate the vaping intensity equations.ResultsWe found evidence that funding for state tobacco control programmes had a significant negative association with both vaping prevalence and vaping intensity among high school students in the USA. Our results indicate that a 50% increase in state spending on tobacco control during the time of the surveys would have been associated with a 7.46% lower high school student vaping prevalence rate than what was observed.ConclusionsThere has been a dramatic increase in e-cigarette use by adolescents and young adults in the USA. The rapid rise in e-cigarette use has been a significant source of public policy concern for many states. The results of this study strongly suggest that increased spending on tobacco control programmes will reduce the number of high school students who vape and will decrease the number of days vaping products are used by high school students. These findings should be extremely valuable to policymakers interested in curbing the youth vaping epidemic in the USA.

Objectives: From 2017 to 2018, electronic cigarette (e-cigarette) use increased 78% among high school students and 48% among middle school students in the United States. However, few e-cigarette prevention interventions have been evaluated. We determined the feasibility and initial effectiveness of “CATCH My Breath,” an e-cigarette prevention program, among a sample of middle schools in central Texas. Methods: Twelve middle schools in Texas (6 intervention schools and 6 control schools) participated in the CATCH My Breath pilot program during 2016-2017. CATCH My Breath is rooted in social cognitive theory, consists of 4 interactive in-class modules, and is collaboratively administered via classroom and physical education teachers, student–peer leaders, and social messaging (eg, school posters). We collected 3 waves of data: baseline (January 2017), 4-month follow-up (May 2017), and 16-month follow-up (May 2018). Using school as the unit of analysis, we tested a repeated cross-sectional, condition-by-time interaction on e-cigarette ever use, psychosocial determinants of use, and other tobacco use behaviors. Analyses controlled for school-level sociodemographic characteristics (eg, sex, race/ethnicity, and percentage of students eligible for free or reduced-price lunch). Results: From baseline to 16-month follow-up, increases in ever e-cigarette use prevalence were significantly lower among intervention schools (2.8%-4.9%) than among control schools (2.7%-8.9%), controlling for covariates ( P = .01). Intervention schools also had significantly greater improvements in e-cigarette knowledge (β = 0.71; 95% confidence interval [CI], 0.21-1.21; P = .008) and perceived positive outcomes (β = –0.12; 95% CI, –0.23 to –0.02; P = .02) than control schools, controlling for covariates from baseline to 16-month follow-up. Conclusion: Ever e-cigarette use was lower among middle schools that implemented the CATCH My Breath program than among those that did not. Replication of findings among a larger sample of schools, using a group-randomized, longitudinal study design and a longer follow-up period, is needed.

Objective: Between 2013 and 2014, past 30-day use of e-cigarettes increased from 4.5% to 13.4% among US high school students aged 9–19 years. We sought to examine the influence of perceived addiction and harm of e-cigarettes on e-cigarette use among adolescents. Design: Self-reported use and perception of harm of e-cigarettes were assessed using a cross-sectional design. Setting: Data were collected from the 2014 National Youth Tobacco Survey. Method: Multivariate logistic regression models were employed regressing lifetime e-cigarette use and past 30-day use on established covariate factors. Results: Perceiving e-cigarettes as less harmful than conventional cigarettes increased students’ odds of lifetime use (odds ratio [ OR] = 2.40, 95% confidence interval [ CI] = 1.98–2.90) and past 30-day use ( OR = 2.18, 95% CI = 1.63–2.92) of e-cigarettes. Perceiving e-cigarettes as less addictive than conventional cigarettes also increased students’ odds of lifetime use ( OR = 2.11, 95% CI = 1.82–2.45) and past 30-day use ( OR = 1.93, 95% CI = 1.57–2.38) of e-cigarettes; however, perceiving e-cigarettes as more addictive than conventional cigarettes also increased students’ odds of lifetime use ( OR = 1.85, 95% CI = 1.37–2.49) and past 30-day use ( OR = 2.68, 95% CI = 1.84–3.90) of e-cigarettes. Other influencing factors of e-cigarette use among youth included race, grade level, living with a smoker and lifetime use of regular cigarettes. Conclusion: The perception that e-cigarettes are less addictive and harmful than their conventional counterparts may be an important risk factor for the use of e-cigarettes. Factors influencing young people’s perceptions need to be examined further.

Residual Confounding

Background: A recent meta-analysis of nine cohort studies in youths reported that baseline ever e-cigarette use strongly predicted cigarette smoking initiation in the next 6-18 months, with an adjusted odds ratio of 3.62 (95% confidence interval 2.42-5.41).  A recent review of e-cigarettes agreed there was substantial evidence for this “gateway effect”.  However, the number of confounders considered in the studies was limited, so we investigated whether the effect might have resulted from inadequate adjustment, using Waves 1 and 2 of the Population Assessment of Tobacco and Health study. Methods: Our main analyses considered Wave 1 never cigarette smokers who, at Wave 2, had information available on smoking initiation.  We constructed a propensity score for ever e-cigarette use from Wave 1 variables, using this to predict ever cigarette smoking.  Sensitivity analyses accounted for use of other tobacco products, linked current e-cigarette use to subsequent current smoking, or used propensity scores for ever smoking or ever tobacco product use as predictors.  We also considered predictors using data from both waves to attempt to control for residual confounding from misclassified responses. Results: Adjustment for propensity dramatically reduced the unadjusted odds ratio (OR) of 5.70 (4.33-7.50) to 2.48 (1.85-3.31), 2.47 (1.79-3.42) or 1.85 (1.35-2.53), whether adjustment was made as quintiles, as a continuous variable or for the individual variables.  Additional adjustment for other tobacco products reduced this last OR to 1.59 (1.14-2.20).  Sensitivity analyses confirmed adjustment removed most of the gateway effect.  Control for residual confounding also reduced the association. Conclusions: We found that confounding is a major factor, explaining most of the observed gateway effect.  However, our analyses are limited by small numbers of new smokers considered and the possibility of over-adjustment if taking up e-cigarettes affects some predictor variables.  Further analyses are intended using Wave 3 data which should avoid these problems.

Normative Expectations

A longitudinal sample of 916 adolescents was examined to assess the extent to which the perceived smoking prevalence of adults' or peers' smoking was related to cigarette smoking. Questionnaires were distributed to junior high school students in Grade 7 and again in Grade 9. Prevalence of perceived peers' smoking and prevalence of perceived adults' smoking were significantly related to cigarette smoking both cross-sectionally and longitudinally. Adolescents who believed that half or more than half of all adults or peers smoked cigarettes showed the most smoking involvement, and those who believed that fewer than half of adults or peers smoked were least involved. These findings provide further evidence that adolescent normative expectations about cigarette smoking are an important determinant of smoking initiation.
