Association between observing peers vaping on campus and E-cigarette use and susceptibility in middle and high school students.

BACKGROUND: This study examines the association between exposure to e-cigarette use on school campus and e-cigarette use behaviors among adolescents in the United States. METHODS: Data were obtained from the 2019 National Youth Tobacco Survey. First, two multivariate logistic regression models examined the association between in-school exposure to e-cigarette use and ever and past 30-day (i.e., current) e-cigarette use. Next, a multivariate logistic regression model to examine the relationship between in-school exposure to e-cigarette use and susceptibility to use was conducted among a subsample (n = 11,958) of never e-cigarette users. Covariates included grade, race/ethnicity, marketing exposure, and ever use of other tobacco products. RESULTS: Approximately 64.3 % of adolescents reported seeing someone use an e-cigarette on school campus; the most common locations being in the bathroom/locker room (34.4 %) and parking lot (34.0 %). In-school exposure to e-cigarette use was associated with greater odds of ever (Adj OR: 2.06; 95 % CI: 1.82-2.33) and current (Adj OR: 1.70; 95 % CI: 1.46-1.98) e-cigarette use among adolescents as well as greater odds of susceptibility to use (Adj OR: 2.00; 95 % CI: 1.82-2.20) among never e-cigarette users. CONCLUSIONS: Observing e-cigarette use on school campus was associated with greater odds of e-cigarette use and susceptibility. It is plausible that observing e-cigarette use on campus reinforces the social acceptability of adolescent e-cigarette use. Findings inform on the prevalence of e-cigarettes use on-campus as well as how this phenomenon may influence e-cigarette use/susceptibility among youth. The observed relationship highlights the role of schools in the efforts to reduce adolescent e-cigarette use.

Dissemination of CATCH My Breath, a middle school E-Cigarette prevention program.

OBJECTIVES: In 2016, the US Surgeon General issued a Call to Action to address adolescent e-cigarette use and school-based prevention interventions are an effective component of comprehensive tobacco control. This study describes the development and dissemination of CATCH My Breath, an e-cigarette prevention program for middle and high school students. METHODS: Starting in 2014, a university and nonprofit collaboration designed, formatively evaluated, pilot tested, and disseminated the CATCH My Breath Program (CMB). The team used Social Cognitive Theory to develop the program and Diffusion of Innovations Theory to disseminate the program. Dissemination strategies were applied beginning in 2016. This paper describes the application of both theories and the resulting reach of CMB. RESULTS: Since dissemination began, CMB has been rapidly adopted, following the typical diffusion normal curve. As of June 2020, approximately 4,000 schools in the United States have adopted the program, 70,000 teachers have taught the program, and 1,400,000 students have been exposed to program materials. CONCLUSION: The application of Social Cognitive Theory and Diffusion of Innovation Theory resulted in effective prevention results and rapid, widespread adoption of the CMB. This level of adoption and implementation represents 25% of the school marketplace. CMB should be considered as the school component of the recommended combustible and e-cigarette prevention and control toolkit, alongside mass media, marketing restrictions, retail access, taxation, flavor ban, and FDA premarket approval. Other public health interventions seeking rapid adoption should consider applying principles of Diffusion of Innovation as a guide for development and dissemination.
