We examined sources of e-cigarette acquisition among youth, and changes in these sources, between 2014 and 2015. We also assessed whether youth were ever refused the sale of e-cigarettes.
Anonymous, cross-sectional surveys conducted in five high schools in 2014 and 2015 in Connecticut assessed demographics, e-cigarette and cigarette use, and e-cigarette acquisition sources (friends/boyfriends/girlfriends, tobacco shops, siblings, online, parents/adult family members, other). We restricted analyses to adolescents younger than 18 years old who had used e-cigarettes in the past month (2014: N = 400, 2015: N = 390).
Top sources of e-cigarette acquisition were friends (2014: 50.2%, 2015: 45.4%), tobacco shops (2014: 17.5%, 2015: 12.6%), and online shops (2014: 9.8%, 2015: 10.5%). A multilevel model, controlling for sex, age, and cigarette smoking status, while clustering by schools showed a decrease in the proportion of youth obtaining e-cigarettes from friends (AOR = .84) between 2014 and 2015. In 2015, 69.8% and 85.8% purchased e-cigarettes from a physical store and an online store, respectively.
Peers were the most popular source of e-cigarette acquisition. Many adolescents were able to purchase e-cigarettes from commercial sources. Future studies should continue to conduct surveillance of where adolescents obtain e-cigarettes to inform prevention strategies.
我们研究了2014年至2015年间青少年获取电子烟的来源以及这些来源的变化。我们还评估了青少年是否曾被拒绝销售电子烟。
2014年和2015年在康涅狄格州的五所高中进行的匿名横断面调查评估了人口统计学、电子烟和香烟使用情况以及电子烟获取来源（朋友/男朋友/女朋友、烟草店、兄弟姐妹、网上、父母/成年家庭成员、其他）。我们将分析限制在过去一个月内使用过电子烟的18岁以下青少年（2014年：N = 400，2015年：N = 390）。
获取电子烟的主要来源是朋友（2014年：50.2%，2015年：45.4%）、烟草店（2014年：17.5%，2015年：12.6%）和网上商店（2014年：9.8%，2015年：10.5%）。一个控制了性别、年龄和吸烟状况的多层次模型，同时按学校进行聚类分析，结果显示2014年至2015年间从朋友处获取电子烟的青少年比例有所下降（调整后比值比 = 0.84）。2015年，分别有69.8%和85.8%的青少年从实体店和网上商店购买了电子烟。
同龄人是获取电子烟最常见的来源。许多青少年能够从商业渠道购买电子烟。未来的研究应继续监测青少年获取电子烟的地点，以为预防策略提供信息。
