新颖、廉价的一次性电子烟以诱人的口味广泛销售，可能不受美国联邦法规的约束。为了告知监管和公共卫生优先事项，这项研究检查了现有烟草使用者与非使用者之间的年轻成人一次性电子烟使用率，以及可能成为潜在监管目标的可能使用相关性。目的和方法分析2021年前瞻性队列数据。在基线（2018-2019年）从未使用过一次性电子烟的人群中（n = 1903;平均值[SD]：19.3 [0.8]岁），我们测试了基线烟草产品使用与后续（2020年）一次性电子烟使用开始的前瞻性关联，然后进行分层分析，区分基线专用和双重电子烟/可燃烟草使用。对当前一次性使用者（n = 266）中烟草相关性与吸烟频率的探索性横断面关联进行了测试。基线前（22.1%）和当前（50.2%）的随访一次性电子烟使用开始率高于从未（6.3%）可充电（非一次性）电子烟使用者。在分层分析中，基线从不吸烟的唯一当前吸烟者的后续一次性电子烟使用开始率为0%，基线从不吸烟的前吸烟者高于从不使用任何烟草产品的人（18.2%对5.7%;校正比值比[95% CI] = 3.9 [2.1-7.5]），基线当前双重用户与从不吸烟的唯一当前vapers相比更高（61.3%对42.2%;调整后的比值比[95% CI] = 3.0 [1.5-6.0]）。在随访的当前一次性电子烟使用者中，（总患病率= 10.9%），使用冰味的（与水果/甜味）电子烟（校正率比[95% CI] = 1.5 [1.0-2.1]）和电子烟依赖症状（校正率比[95% CI] = 2.2 [1.5-3.2]）与上个月一次性电子烟使用天数更多相关。结论：年轻人使用一次性电子烟的流行程度相当高，包括从未使用过烟草产品和曾经吸烟的人。对包括冰味产品在内的一次性电子烟的监管可能有利于年轻人的健康。从2019年到2020年，一次性电子烟产品在美国的销量大幅增长。这些产品含有高尼古丁浓度和各种口味，可能会吸引年轻人。这项研究提供了第一个证据，表明一次性电子烟的使用在年轻人中可能很常见，包括从未使用过烟草产品和曾经吸烟的人。一次性电子烟的使用频率与使用冰味电子烟和电子烟依赖呈正相关。针对一次性电子烟的监管政策和执法战略值得在青少年健康政策和预防优先事项中加以考虑。
Introduction Novel, inexpensive disposable e-cigarettes widely sold in attractive flavors might be exempt from US federal regulations. To inform regulatory and public health priorities, this study examined young adult disposable e-cigarette use uptake among existing tobacco users versus non-users and possible use correlates that could be potential regulatory targets. Aims and Methods Prospective cohort data were analyzed in 2021. Among baseline (2018-2019) never disposable e-cigarette users (n = 1903; mean [SD]: 19.3 [0.8] years-old), we tested prospective associations of baseline tobacco product use with follow-up (2020) disposable e-cigarette use initiation, followed by stratified analyses distinguishing baseline exclusive and dual e-cigarette/combustible tobacco use. Exploratory cross-sectional associations of tobacco-related correlate with vaping frequency among current disposable users (n = 266) were tested. Results Follow-up ever disposable e-cigarette use initiation was higher among baseline former (22.1%) and current (50.2%) versus never (6.3%) rechargeable (non-disposable) e-cigarette users. In stratified analyses, follow-up disposable e-cigarette use initiation was 0% in baseline never-vaping exclusive current smokers, higher in baseline never-vaping former smokers versus never users of any tobacco product (18.2% vs. 5.7%; adjusted odds ratio [95% CI] = 3.9 [2.1-7.5]), and higher among baseline current dual users versus never-smoking exclusive current vapers (61.3% vs. 42.2%; adjusted odds ratio [95% CI] = 3.0 [1.5-6.0]). Among follow-up current disposable e-cigarette users (overall prevalence = 10.9%), using ice-flavored (vs. fruit/sweet-flavored) e-cigarettes (adjusted rate ratio [95% CI] = 1.5 [1.0-2.1]) and vaping dependence symptoms (adjusted rate ratio [95% CI] = 2.2 [1.5-3.2]) were cross-sectionally associated with more past-month disposable e-cigarette use days. Conclusions Young adult disposable e-cigarette use was of appreciable prevalence, including among tobacco product never users and former smokers. Regulation of disposable e-cigarettes, including ice-flavored products, might benefit young adult health. Implications Sales of disposable e-cigarette products increased significantly in the United States from 2019 to 2020. These products contain high nicotine concentrations and various flavors that may appeal to young people. This study provides the first evidence that disposable e-cigarette use may be common among young adults, including among tobacco product never users and former smokers. Frequency of disposable e-cigarette use was positively associated with using ice-flavored e-cigarettes and vaping dependence. Regulatory policies and enforcement strategies addressing disposable e-cigarettes merit consideration in young adult health policy and prevention priorities.
