背景：需要进行纵向研究来确定青少年持续使用电子烟的预测因素。我们预计，首次尝试电子烟的某些原因会预测随着时间的推移继续使用电子烟（例如，味道好、朋友使用），而其他原因不会预测继续使用（例如，好奇心）。 方法：使用 2013 年秋季（第一波）和 2014 年春季（第二波）对中学生和高中生的纵向调查来检验尝试电子烟的原因，作为随着时间的推移持续使用电子烟的预测因素。第 1 波曾经使用过电子烟的用户 (n = 340) 被分为第 2 波使用或不使用电子烟的用户。在那些继续使用电子烟的人中，尝试电子烟的原因被检查为使用频率的预测因素，以过去 30 天在第 2 波使用电子烟的天数来衡量。协变量包括年龄、性别、种族和吸烟传统香烟。结果：首次尝试电子烟的几个预测原因持续存在使用，包括低成本、能够在任何地方使用电子烟以及戒掉普通香烟。由于成本低廉而尝试电子烟也预示着第二波电子烟使用天数会增加。年轻或当前吸烟者也预示着随着时间的推移会继续使用和更频繁地使用电子烟。结论：增加成本或禁止在某些地方使用电子烟等监管策略对于防止青少年继续使用电子烟可能很重要。此外，可能还需要针对当前吸烟者和年龄较小的学生采取干预措施。
BACKGROUND: Longitudinal research is needed to identify predictors of continued electronic cigarette (e-cigarette) use among youth. We expected that certain reasons for first trying e-cigarettes would predict continued use over time (eg, good flavors, friends use), whereas other reasons would not predict continued use (eg, curiosity).METHODS: Longitudinal surveys from middle and high school students from fall 2013 (wave 1) and spring 2014 (wave 2) were used to examine reasons for trying e-cigarettes as predictors of continued e-cigarette use over time. Ever e-cigarette users (n = 340) at wave 1 were categorized into those using or not using e-cigarettes at wave 2. Among those who continued using e-cigarettes, reasons for trying e-cigarettes were examined as predictors of use frequency, measured as the number of days using e-cigarettes in the past 30 days at wave 2. Covariates included age, sex, race, and smoking of traditional cigarettes.RESULTS: Several reasons for first trying e-cigarettes predicted continued use, including low cost, the ability to use e-cigarettes anywhere, and to quit smoking regular cigarettes. Trying e-cigarettes because of low cost also predicted more days of e-cigarette use at wave 2. Being younger or a current smoker of traditional cigarettes also predicted continued use and more frequent use over time.CONCLUSIONS: Regulatory strategies such as increasing cost or prohibiting e-cigarette use in certain places may be important for preventing continued use in youth. In addition, interventions targeting current cigarette smokers and younger students may also be needed.
