背景：关于电子烟（电子烟）的使用与某些产品特性以及青少年和年轻人不健康烟草使用模式（例如，吸食可燃香烟的频率）的风险之间的关联，缺乏证据，这是为电子烟的监管提供信息所必需的。方法：通过2015年至2016年（基线）和2016年至2017年（随访）南加州儿童健康研究参与者的在线调查收集数据（N = 1312）。在1年随访中，我们评估了最常使用的电子烟的3个非互斥特征的二分类与过去30天内吸烟数量的关联。产品特性包括设备（电子烟笔和/或可改装电子烟[mod]），尼古丁在电子液体中使用（电子液体，是或否），以及使用滴灌（直接将电子液体滴到设备上，是或否）。结果：与从不吸电子烟的人相比，在随访中，过去30天吸电子烟的人吸烟的频率更高。在过去30天的基线电子烟使用者中，在调整了社会人口统计学特征、吸烟基线频率和电子烟使用天数后，使用mods（与vape笔相比）的参与者在随访时吸烟的数量是前者的6倍（平均：20.8支vs 1.3支；比率= 6.33；95%置信区间：1.64-24.5）。调整装置后，尼古丁电子液和尼古丁滴液与吸烟频率无关。结论：在过去30天的随访中，基线mod使用者（与vape pen使用者相比）吸烟更多。对电子烟设备类型的监管值得考虑，作为减少使用电子烟的青少年和年轻人吸烟的策略。在这项研究中，我们试图确定电子烟产品特性是否与过去30天的吸烟频率相关，类似于一年后的吸烟频率。
BACKGROUND: There is a dearth of evidence regarding the association of use of electronic cigarettes (e-cigarettes) with certain product characteristics and adolescent and young adult risk of unhealthy tobacco use patterns (eg, frequency of combustible cigarette smoking), which is needed to inform the regulation of e-cigarettes. METHODS: Data were collected via an online survey of participants in the Southern California Children's Health Study from 2015 to 2016 (baseline) and 2016 to 2017 (follow-up) (N = 1312). We evaluated the association of binary categories of 3 nonmutually exclusive characteristics of the e-cigarette used most frequently with the number of cigarettes smoked in the past 30 days at 1-year follow-up. Product characteristics included device (vape pen and/or modifiable electronic cigarette [mod]), use of nicotine in electronic liquid (e-liquid; yes or no), and use for dripping (directly dripping e-liquid onto the device; yes or no). RESULTS: Relative to never e-cigarette users, past-30-day e-cigarette use was associated with greater frequency of past-30-day cigarette smoking at follow-up. Among baseline past-30-day e-cigarette users, participants who used mods (versus vape pens) smoked >6 times as many cigarettes at follow-up (mean: 20.8 vs 1.3 cigarettes; rate ratio = 6.33; 95% confidence interval: 1.64-24.5) after adjustment for sociodemographic characteristics, baseline frequency of cigarette smoking, and number of days of e-cigarette use. After adjustment for device, neither nicotine e-liquid nor dripping were associated with frequency of cigarette smoking. CONCLUSIONS: Baseline mod users (versus vape pen users) smoked more cigarettes in the past 30 days at follow-up. Regulation of e-cigarette device type warrants consideration as a strategy to reduce cigarette smoking among adolescents and young adults who vape.In this study, we sought to determine if e-cigarette product characteristics were associated with past-30-day frequency of cigarette smoking similar to 1 year later.
