Convenience Store Access and E-cigarette Advertising Exposure Is Associated With Future E-cigarette Initiation Among Tobacco-Naïve Youth in the PATH Study (2013–2016)

Youth electronic cigarette (e-cigarette) use is a global health challenge, with multiple jurisdictions wrestling with appropriate responses, in the face of limited evidence available on effective interventions. Identifying and synthesising evidence on the effects of interventions to prevent youth e-cigarette use is required to inform prevention-focussed health policy and practice. We plan to undertake an individual participant data (IPD) prospective meta-analysis (PMA). We will conduct systematic searches to identify eligible planned or ongoing randomised controlled trials (RCTs) using trial registries via WHO ICTRP and ClinicalTrials.gov and databases Medline, Embase, CENTRAL, PsycINFO, Web of Science, CINAHL and Europe PMC. We will also search grant websites for additional studies. We will include any RCT of e-cigarette and cigarette prevention interventions for youth including non-smoking and non-vaping youth aged 10 to 19 years, with no intervention, waitlist, usual care or active control. Primary outcomes will be measures of current or ever e-cigarette use. Secondary outcomes include measures of current and ever cigarette (conventional cigarette) use.Investigators from relevant trials will be invited to join the Synthesis using Prospective meta-Analysis to Reduce youths' E-cigarette use (SPARKE) consortium prior to trial outcomes being known using harmonised methods. They are then asked to share their data within 12 months of trial completion.The primary outcomes will be analysed in a two-stage IPD meta-analysis model under an intention-to-treat framework. First, effect estimates and variances will be calculated for each trial with log-binomial regression models adjusting for key prognostic factors. For cluster RCTs, a nested random effect will be specified within trials to account for correlations within clusters. Second, effect estimates will be combined across trials in a random treatment effect, inverse variance meta-analysis model. Effect estimates will be reported as relative risk ratios with 95% CIs. This study aims to generate and expedite the synthesis of data regarding prevention interventions for adolescent e-cigarette use to inform real-world decision making. Findings will be of interest to key stakeholders, including policy makers and research funders. Each trial will be responsible for obtaining their own ethics approval. While secondary analysis of data does not usually require ethics approval, we have received cross-institutional ethics approval from the University of Sydney (2023/714) and the University of Newcastle (H-2023-0389).

BackgroundWe examined whether the implementation of electronic cigarette (e-cigarette) policies at the state level (e-cigarette-inclusive smoke-free (ESF) policies, excise taxes on e-cigarettes and raising tobacco legal purchasing age to 21...

Parents are essential stakeholders for policy implementation. However, data on parents' support for e-cigarette- and tobacco-related policies is limited. This study examines parents' support for five e-cigarette- and tobacco-related policies targeted to prevent youth initiation and exposure to industry marketing practices. Data were from a 2018 nationally representative sample of US parents of 11- to 18-year-old middle and high school students. Weighted adjusted logistic regression models examined correlates of support for policy outcomes, controlling for demographics. Analyses were performed among the full sample (n = 2743) and among current tobacco users (n = 355). The majority of parents, including current tobacco users, supported tobacco control efforts to protect adolescents. More than 90% of all parents supported restrictions on e-cigarette marketing to youth and 75% supported a ban on flavored e-cigarette sales. Additionally, more than 80% of all parents supported increasing the age of tobacco product sale to 21, limiting tobacco retailer density near schools, and keeping tobacco products out of view where youth shop. Presence of strict home tobacco rules or reporting a high priority to prevent child's e-cigarette use were significantly associated with higher odds of policy support. Results were similar among current tobacco users. Parents are an important group of tobacco control stakeholders and should be utilized to garner support for tobacco control policies in the context of the recent growth in youth tobacco and e-cigarette use. Parents' public support for tobacco control policies, particularly regulations on e-cigarette sales and marketing, can motivate advocates and policymakers to advance tobacco control policy agendas. Youth tobacco and e-cigarette use in the United States has increased in recent years. Parents are important stakeholders to inform policy agendas and advance efforts to restrict youth access and exposure to tobacco products. This study provides evidence that parents of adolescents are highly supportive of youth-centered tobacco control policies, particularly those that restrict access to youth-targeted e-cigarette marketing and the sale of youth-appealing flavored e-cigarettes. Utilizing policy support to mobilize parents may be an important advocacy strategy to advance tobacco control policy agendas and curb rising rates of youth e-cigarette and tobacco use.

E-cigarette susceptibility among U.S. middle and high school students: National Youth Tobacco Survey Data Trend Analysis, 2014–2018

Existing research on mental health comorbidities of youth e-cigarette use is subject to confounding bias and reverse causality. This study aimed to measure the effects of e-cigarette use on youth mental health, using e-cigarette minimum legal age (MLA) law in Canada as a natural experiment. We used difference-in-differences (DD), difference-in-differences-in-differences (DDD) and two-sample instrumental variables (TSIV) methods. Data were from nationally representative Canadian Community Health Surveys 2008-2019 and Canadian Student Tobacco Alcohol and Drugs Surveys 2008-2019. The study sample comprised of respondents aged 15 to 18 (in DD analysis; n = 33 858) and aged 15 to 24 (in DDD analysis; n = 78 689). Primary outcomes were self-reported mood disorders and anxiety disorders. Secondary outcomes were cannabis use, illicit drug use, cigarette use and strength of peer relationships at schools. After the e-cigarette MLA laws, risks of mood disorders declined by 1.9 percentage points (95% CI, 0.0-3.8; P =0.05) in the DD analysis and by 2.6 percentage points (95% CI, 0.2-5.0; P =0.03) in the DDD analysis. For anxiety disorders, while the DD estimate was negative but imprecisely estimated, the MLA law reduced risks of anxiety disorder by 3.6 percentage points (95% CI, 0.9-6.2; P = 0.01) in the DDD analysis. Youths in provinces with MLA laws were also less likely to report cannabis use and illicit drug use and more likely to feel being part of schools. TSIV analysis indicates that youth e-cigarette use increased the likelihood of mood and anxiety disorders by 44% and 37%, respectively. In Canada, the e-cigarette minimum legal age law appears to have reduced risks of mood and anxiety disorders, lowered substance use and improved peer relationships at schools. Combined with previous evidence of lower e-cigarette use following the minimum legal age law, our findings indicate that youth e-cigarette use increases risks of mood and anxiety disorders.

In 2016, the Surgeon General used longitudinal cohort studies to conclude that youth e-cigarette use is strongly associated with cigarette use. We re-evaluate data from the period of time before the writing of the Surgeon General report, using quasi-experimental methods, and reach the opposite conclusion. We study contemporaneous and intertemporal effects of e-cigarette and cigarette price and tax changes. Our price variation comes from 35,000 retailers participating in the Nielsen Retail Scanner data system. We match price and tax variation to survey data on current use of e-cigarettes and cigarettes for over 94,000 students between grades 6 to 12 in the National Youth Tobacco Survey (NYTS) for years 2011 to 2015. We find evidence that e-cigarettes and cigarettes are same-period economic substitutes. Coefficient estimates (while imprecisely estimated) also suggest potentially large positive effects of past e-cigarette prices on current cigarette use, indicating inter-temporal economic substitution. Our findings raise doubts about the conclusion of government-sponsored reports that e-cigarettes and cigarettes are strongly positively associated. We recommend revisiting and possibly amending this conclusion.

E-cigarettes (electronic cigarettes) have been the most used tobacco product among US youth since 2014, reaching a plateau during the COVID-19 pandemic. Youth e-cigarette use is associated with negative health consequences such as impaired cognitive functioning. For many, the COVID-19 pandemic altered social interactions, harm perceptions, and product availability. This changed the frequency and locations in which youth use e-cigarettes. To better understand youth e-cigarette use, we need more information on factors that can alter e-cigarette use, specifically, how the pandemic changed e-cigarette use among youth. In 2020-2021, we conducted online, individual interviews with 19 youth (aged 13-17) e-cigarette users living in the US to explore how COVID-19 impacted their e-cigarette use. Youth described a progression of e-cigarette use from initial experimentation, regular social use, and ultimately to nicotine addiction demonstrated by individual use in isolation. Many youth initiated e-cigarette use due to influences by friends or family members. Youth discussed progression to social use, with social interactions as an important reason for use and an avenue for expanding one’s knowledge of e-cigarettes. After a period of time, youth began to recognize that the social interactions mattered less, suggesting to them that they had become addicted. This realization became more apparent during COVID-19, which changed how youth used e-cigarettes, especially around where use was occurring, health concerns, and use behavior and frequency. In our interviews, youth trajectory began with an initiation with family and friends, progressed to social use, and eventually developed to addiction, at which point social use was no longer the primary motivation for e-cigarette use. Understanding the trajectory of e-cigarette use will allow for effective interventions that reduce harm to youth from e-cigarette use.

Electronic cigarettes and conventional cigarette use among US adolescents [published online ahead of print March 6, 2014]. JAMA Pediatrics; doi: https://doi.org/10.1001/jamapediatrics.2013.5488 Investigators from the University of California, San Francisco conducted a study to examine the relationship between electronic cigarette (e-cigarette) use and both conventional cigarette use and smoking cessation among US adolescents. The researchers used data from the 2011 and 2012 National Youth Tobacco Survey, a nationally representative, cross-sectional sample of US middle and high school students (grades 6–12) for the study. The self-administered questionnaire included indicators of tobacco use, intention to quit, and smoking cessation. Conventional cigarette users were defined as experimenters (ever tried ≥1 puff), ever smokers (≥100 cigarettes smoked), or current smokers (≥100 cigarettes smoked in last 30 days). Conventional cigarette abstinence was measured at 30 days, 6 months, and 1 year. Participants who responded that they had used “electronic cigarettes or e-cigarettes, such as Ruyan or NJOY” were defined as ever e-cigarette users (ever tried) or current users (used on ≥1 day in the past 30 days). Multivariable logistic regression was used to evaluate the relationship between e-cigarette use and tobacco cigarette use and cessation. The investigators analyzed data from 17,353 respondents in 2011 and 22,539 in 2012. Among cigarette experimenters, ever e-cigarette use was associated with higher odds of being classified as an “ever smoker” (OR = 6.31; 95% CI, 5.39–7.39) and current cigarette smoking (OR = 5.96; 95% CI, 5.67–6.27). Current e-cigarette use was also associated with higher odds of ever having smoked cigarettes (OR = 7.42; 95% CI, 5.63–9.79) and current cigarette smoking (OR = 7.88; 95% CI, 6.01–10.32). For 2011 study participants, current cigarette smokers who had ever used e-cigarettes were more likely to intend to quit smoking within the next year (OR = 1.53; 95% CI, 1.03–2.28). Among cigarette experimenters and ever cigarette smokers, ever e-cigarette use and current e-cigarette use was associated with lower odds of abstinence from cigarettes at 30 days, 6 months, and 1 year. The investigators conclude that e-cigarettes do not discourage use, and may be encouraging use, of conventional cigarettes among US adolescents. They suggest that their results contradict claims that e-cigarettes are effective as smoking cessation aids. Dr Wong has disclosed no financial relationship relevant to this commentary. This commentary does not contain a discussion of an unapproved/investigative use of a commercial product/device. Adult and youth e-cigarette use has been rapidly rising. In another analysis of the NYTS data, e-cigarette use among youth in grades 6 to 12 doubled, from 3.3% in 2011 to 6.8% in 2012.1 With these increasing rates, the public debate on the impact of e-cigarettes and other electronic nicotine delivery systems on public health has intensified. Other nicotine delivery systems include emerging e-cigarette-like devices marketed under different names, such as “e-hookahs” or “vape pipes,” which may result in considerable underestimates of youth e-cigarette use.2 While e-cigarettes contain fewer toxins and lower levels of these toxins compared to conventional cigarettes, they...
