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.
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.
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.
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.
本研究调查了美国校园内电子烟使用暴露与青少年电子烟使用行为之间的关联。
数据来自 2019 年全国青少年烟草调查。首先，采用两个多变量逻辑回归模型检验了校内电子烟使用暴露与曾经使用和过去 30 天（即当前）电子烟使用之间的关联。其次，在从未使用过电子烟的亚样本（n=11958）中，采用多变量逻辑回归模型检验了校内电子烟使用暴露与使用易感性之间的关系。协变量包括年级、种族/族裔、营销暴露和曾经使用其他烟草制品。
约 64.3%的青少年报告在校园内看到有人使用电子烟；最常见的地点是浴室/更衣室（34.4%）和停车场（34.0%）。校内电子烟使用暴露与青少年曾经使用电子烟（调整后的优势比：2.06；95%置信区间：1.82-2.33）和当前使用电子烟（调整后的优势比：1.70；95%置信区间：1.46-1.98）的几率增加以及从未使用过电子烟的青少年使用易感性增加（调整后的优势比：2.00；95%置信区间：1.82-2.20）有关。
观察到校园内电子烟使用与电子烟使用和易感性增加的几率增加有关。在校园内观察到电子烟使用可能会增强青少年电子烟使用的社会可接受性，这种可能性是合理的。研究结果表明了校园内电子烟使用的普遍性，以及这种现象如何影响青少年电子烟使用/易感性。观察到的关系突出了学校在减少青少年电子烟使用方面的作用。
