We examined the relationships between e-cigarette use and subsequent cigarette smoking behaviors at 6- and 12-month follow-ups among young adults.
Participants were 18-29 year-old current and former cigarette smokers (N = 627) at 24 Texas colleges, participating in a 3-wave study. Multi-level, multivariable logistic regression models, accounting for school clustering, examined the impact of self-reported use of e-cigarettes on cigarette smoking status at 6- and 12-month follow-ups. Two mutually-exclusive groups of e-cigarette users were examined: those that used for cigarette smoking cessation and those that used for reasons other than cessation. Baseline covariates included socio-demographics, past quit attempts, nicotine dependence, cigarettes per day, and other tobacco use.
Use of e-cigarettes for cigarette smoking cessation was associated with increased odds of cigarette smoking cessation at 6- and 12-month follow-ups, while using e-cigarettes for other reasons was not, when adjusting for covariates.
Use of e-cigarettes for cigarette smoking cessation may reduce cigarette smoking rates in young adult college students. Additional research is needed examining e-cigarettes as a complement to evidence-based cessation resources that are associated with cigarette smoking cessation among young adults.
我们研究了在6个月和12个月随访时，年轻成年人中电子烟使用与后续吸烟行为之间的关系。
参与者为德克萨斯州24所大学中年龄在18 - 29岁的当前和曾经吸烟者（N = 627），参与一项三波研究。考虑学校聚类的多层次多变量逻辑回归模型，研究了自我报告的电子烟使用对6个月和12个月随访时吸烟状况的影响。研究了两组相互排斥的电子烟使用者：用于戒烟的使用者和因其他原因使用的使用者。基线协变量包括社会人口统计学、过去的戒烟尝试、尼古丁依赖、每日吸烟量以及其他烟草使用情况。
在调整协变量后，使用电子烟戒烟与6个月和12个月随访时戒烟几率增加相关，而因其他原因使用电子烟则不然。
使用电子烟戒烟可能会降低年轻成年大学生的吸烟率。需要进一步研究将电子烟作为与年轻成年人戒烟相关的循证戒烟资源的补充。
