电子烟（EC）在青少年中越来越受欢迎，他们认为电子烟比香烟“更安全”。虽然研究已经检查了青少年使用EC的危险因素，但对EC使用与健康状况和保护性健康行为的关系知之甚少。平均年龄17.31岁，标准差0.67; 46%的男性）完成了一项关于EC和香烟使用、身心健康、体育活动、饮食、睡眠以及酒精和其他药物（AOD）使用的调查。Logistic回归分析比较了仅使用EC的人与双EC/香烟使用者、仅使用避孕药的人和非使用者在这些健康因素上的差异。在仅使用EC的用户中，单独的普通最小二乘回归模型评估了健康状况/行为变量对过去一年EC使用频率的影响，控制了人口统计数据和无烟烟草使用。结果：用户组在身体健康和参与保护健康行为方面相似（体力活动，睡眠持续时间/质量，健康饮食），但仅使用EC的用户报告的心理健康症状较少，且使用AOD的人数少于双重或仅使用EC的用户。在仅使用EC的人群中，AOD使用（P < 0.0001）预测更频繁的EC使用;健康饮食预测更少的EC使用（P < 0.01）。结论：与吸烟相比，仅使用EC与更低的危险行为参与相关，但与更好的健康状况或更高的保护性健康行为参与相关。双重EC/香烟使用者可能是一个特别高的风险群体，因为他们更多地使用AOD和香烟消费。在“中等风险”的仅使用EC的用户中，AOD的使用和不健康的饮食与更重的使用相关，并且可能是防止升级到更有害的烟草使用的重要目标。
Objectives: E-cigarettes (ECs) are increasingly popular among adolescents, who perceive them as "safer'' than cigarettes. Although research has examined risk factors for adolescent EC use, little is known about how EC use correlates with health status and protective health behaviors.Methods: In all, 2488 adolescents (mean age = 17.31 years, SD = 0.67; 46% male) completed a survey on EC and cigarette use, physical and mental health, physical activity, diet, sleep, and alcohol and other drug (AOD) use. Logistic regression compared EC-only users to dual EC/cigarette users, cigarette-only users, and nonusers on these health factors. Among EC-only users, separate ordinary least-squares regression models assessed the effects of health status/behavior variables on frequency of past-year EC use, controlling for demographics and smokeless tobacco use.Results: User groups were similar on physical health and engagement in protective health behaviors (physical activity, sleep duration/quality, healthy diet), but EC-only users reported fewer mental health symptoms and less AOD use than dual or cigarette-only users. Among EC-only users, AOD use (all P < 0.0001) predicted more frequent EC use; healthy diet predicted less frequent use (P < 0.01).Conclusions: EC-only use is associated with lower engagement in risky behaviors, but not better health status or higher engagement in protective health behaviors, compared with cigarette smoking. Dual EC/cigarette users may represent a particularly high-risk group due to their greater AOD use and cigarette consumption. Among "intermediate-risk'' EC-only users, AOD use and unhealthy diet correlated with heavier use, and may be important targets for preventing escalation to more harmful tobacco use.
