Abstract

OBJECTIVE

-cigarette use has risen markedly among young adults, despite efforts to curb this trend. To inform future programs and policies, we sought to identify longitudinal correlates of quitting e-cigarette use in the United States (US).

METHODS

The study design was longitudinal. A nationally representative sample of 1138 US adults and adolescents who used e-cigarettes took a baseline online survey between Nov 2022 and Jan 2023. Six months later, 844 respondents completed a follow-up survey. Analyses used weighted simultaneous multivariable logistic regression that included demographic and vaping characteristics assessed at baseline to predict quitting e-cigarettes at 6-month follow-up.

RESULTS

At 6-month follow up, 15 % of respondents had quit e-cigarettes. Quitting was associated with having stronger quit intentions (adjusted odds ratio [aOR] = 1.49, 95 % CI = 1.09, 2.04), occasional use (aOR = 5.93, 95 % CI = 3.11, 11.30), and lower nicotine dependence (aOR = 2.56, 95 % CI = 1.38, 4.76). Quitting was also more common among gay, lesbian, or bisexual respondents than straight respondents (22 % vs. 13 %, aOR = 2.20, 95 % CI = 1.10, 4.38) and females than males (18 % vs. 11 %, OR 1.88; 95 % CI 1.06, 3.34).

CONCLUSIONS

Greater motivation to quit and lower markers of nicotine dependence were associated with quitting vaping at 6 months. Interventions focused on reducing nicotine dependence and increasing quit intentions, especially among daily users, could support e-cigarette cessation.

摘要

目的

尽管采取了各种措施来遏制这一趋势，但美国年轻人中电子烟的使用仍显著增加。为了给未来的项目和政策提供参考依据，我们试图确定美国电子烟使用者戒烟的纵向相关因素。

方法

本研究采用纵向研究设计。2022年11月至2023年1月期间，对1138名使用电子烟的美国成年人及青少年进行了具有全国代表性的抽样调查，并开展了基线在线调查。六个月后，844名受访者完成了随访调查。分析采用加权同时多变量逻辑回归，纳入基线时评估的人口统计学和电子烟使用特征，以预测6个月随访时的戒烟情况。

结果

在6个月的随访中，15%的受访者已经戒掉了电子烟。戒烟与更强的戒烟意愿（调整后的优势比[aOR]=1.49，95%置信区间[CI]=1.09，2.04）、偶尔使用电子烟（aOR=5.93，95%CI=3.11，11.30）以及较低的尼古丁依赖程度（aOR=2.56，95%CI=1.38，4.76）相关。与异性恋受访者相比，男同性恋、女同性恋或双性恋受访者戒烟更为常见（22%对13%，aOR=2.20，95%CI=1.10，4.38）；与男性相比，女性戒烟更为常见（18%对11%，优势比1.88；95%CI 1.06，3.34）。
