This study examines the association between current e-cigarette use at baseline and regular cigarette smoking at follow-up among U.S. youth.
A longitudinal analysis of youth (aged 12-17 years) data from Waves 1-3 of the Population Assessment of Tobacco and Health Study (2013-2016) was conducted between January 2019 and December 2019. Youth who reported past-30-day current e-cigarette use at baseline were identified and followed for regular cigarette smoking (≥20 days) at follow-up.
Compared with noncurrent e-cigarette users at baseline, current e-cigarette users (cigarette nonsmokers) had 5.0 (95% CI=1.9, 12.8) times higher odds of becoming regular cigarette smokers 1 year later. Additionally, there was a direct linear relationship between the number of days of e-cigarette use at baseline and the number of days of cigarette smoking 1 year later.
Current e-cigarette use among U.S. youth is associated with higher odds of transitioning to regular cigarette smoking, likely reflecting robust transitions rather than experimentation. These results suggest that promoting e-cigarettes as the current practice for tobacco harm reduction will likely have the unintended consequence of initiating youth cigarette smokers.
本研究考察了美国青少年在基线时当前使用电子烟与随访时定期吸烟之间的关联。
对 2013-2016 年期间进行的人口烟草与健康评估研究（Population Assessment of Tobacco and Health Study，PATH）第 1-3 波的青少年（年龄为 12-17 岁）数据进行了纵向分析。在基线时报告过去 30 天内当前使用电子烟的青少年被确定，并随访他们在随访时是否定期吸烟（≥20 天）。
与基线时非当前电子烟使用者相比，当前电子烟使用者（非吸烟者）在 1 年后成为定期吸烟者的可能性高 5.0 倍（95%CI=1.9，12.8）。此外，基线时电子烟使用天数与 1 年后吸烟天数之间存在直接线性关系。
美国青少年中当前使用电子烟与更高的定期吸烟可能性相关，这可能反映了从电子烟向香烟的直接转变，而不是尝试吸烟。这些结果表明，推广电子烟作为当前减少烟草危害的方法可能会产生意想不到的后果，即引发青少年吸烟。
