E-cigarette use increased dramatically among U.S. students during 2017-2019, and school plays an important role in preventing and reducing youth substance use. This study examines the prevalence and correlates of self-reported youth observation of e-cigarette use on school grounds.
Data from the 2019 National Youth Tobacco Survey (N=19,018) were analyzed to examine the prevalence and factors associated with youth observation of e-cigarette use in or around the school. Multivariable logistic regressions were performed to assess the associations between youth observation of e-cigarette use and the susceptibility to initiate cigarettes or e-cigarettes. Analyses were conducted in 2020.
In 2019, about 63.9% of students (16.8 million) reported noticing youth use of e-cigarettes in or around the school, with bathroom or locker room as the most common location (33.2%). Female (versus male) students; high-school (versus middle-school) students; non-Hispanic Whites (versus other groups); former and past 30-day e-cigarette users (versus never users); students with exposure to tobacco marketing (versus none); and students living with a household member using e-cigarettes (versus not) had higher odds of reporting the observation of vaping in schools. Among never tobacco users (n=11,518), observation of vaping in schools was associated with higher odds of being susceptible to smoking cigarettes (AOR=1.2, 95% CI=1.0, 1.3) and using e-cigarettes (AOR=1.7, 95% CI=1.6, 1.9), especially among middle-school students.
E-cigarette use is common on school grounds, and youth observation of vaping in schools may increase the risk of initiating tobacco use in the future. School vaping policy and education programs are needed to curb youth e-cigarette use.
2017 - 2019年间，美国学生中电子烟的使用急剧增加，学校在预防和减少青少年物质使用方面发挥着重要作用。本研究调查了学生自我报告在校园内观察到电子烟使用的流行情况及其相关因素。
分析了2019年全国青少年烟草调查的数据（N = 19,018），以研究在学校内或学校周边青少年观察到电子烟使用的流行情况及相关因素。进行多变量逻辑回归分析，以评估青少年观察到电子烟使用与开始使用香烟或电子烟易感性之间的关联。分析于2020年进行。
2019年，约63.9%的学生（1680万）报告在学校内或学校周边注意到青少年使用电子烟，其中浴室或更衣室是最常见的地点（33.2%）。女性（与男性相比）学生；高中生（与初中生相比）；非西班牙裔白人（与其他群体相比）；曾经使用过电子烟和过去30天内使用过电子烟的学生（与从未使用者相比）；接触过烟草营销的学生（与未接触者相比）；以及与使用电子烟的家庭成员同住的学生（与未同住者相比），报告在学校观察到电子烟使用的几率更高。在从未使用过烟草的学生（n = 11,518）中，在学校观察到电子烟使用与开始吸烟（调整后比值比[AOR]=1.2，95%置信区间[CI]=1.0, 1.3）和使用电子烟（AOR = 1.7，95% CI = 1.6, 1.9）的较高易感性相关，尤其是在初中生中。
在校园内电子烟使用很普遍，青少年在学校观察到电子烟使用可能会增加未来开始使用烟草的风险。需要制定学校电子烟政策和教育计划来遏制青少年电子烟的使用。
