There is a lack of evidence for the impact of school-based e-cigarette interventions among current e-cigarette users. This natural experimental evaluation study evaluated the one-year impact of various school-based e-cigarette prevention/cessation programs among a sample of current youth e-cigarette users. The COMPASS study sample included = 3586 current e-cigarette users from = 90 schools with data collected between 2017 and 2019. Student e-cigarette use patterns were categorized as "escalated", "maintained", and "reduced" based on the change in past 30-day e-cigarette use between baseline and follow-up. Intervention schools added e-cigarette use "prevention", "cessation", or "protection" programs, while control schools did not make any changes. Logistic regression models identified how each category of added programs was associated with e-cigarette use patterns. About one quarter of schools added an e-cigarette use prevention/cessation program over one year. Student e-cigarette use patterns between control and intervention groups differed in proportion ranging from a decrease of 3.35% to an increase of 5.80%. Regression models did not identify any significant differences in the odds of escalating or reducing e-cigarette use in intervention relative to control schools. While many schools implemented new e-cigarette programs over one year, none of the interventions led to significant changes in e-cigarette escalation or reduction among current youth e-cigarette users. Additional studies are needed to evaluate the impact of e-cigarette interventions among current e-cigarette users.
目前，针对基于学校的电子烟干预措施对当前电子烟使用者影响的证据不足。本自然实验评估研究评估了在当前青少年电子烟使用者样本中，各种基于学校的电子烟预防/戒烟计划在一年内的影响。COMPASS 研究样本包括来自 90 所学校的 3586 名当前电子烟使用者，数据收集于 2017 年至 2019 年之间。根据基线和随访期间过去 30 天电子烟使用量的变化，学生电子烟使用模式分为“升级”、“维持”和“减少”。干预学校增加了电子烟使用“预防”、“戒烟”或“保护”计划，而对照学校没有进行任何改变。逻辑回归模型确定了添加的每个类别的计划与电子烟使用模式之间的关联方式。大约四分之一的学校在一年内增加了电子烟使用预防/戒烟计划。在控制组和干预组之间，学生电子烟使用模式的比例存在差异，范围从减少 3.35%到增加 5.80%。回归模型未发现干预组相对于对照组在增加或减少电子烟使用的几率方面存在任何显著差异。虽然许多学校在一年内实施了新的电子烟计划，但没有一项干预措施导致当前青少年电子烟使用者电子烟使用量的显著变化。需要进一步研究来评估电子烟干预措施对当前电子烟使用者的影响。
