The purpose of this study is to examine associations between reasons for e-cigarette use and e-cigarette use frequency, dependence, and quit intentions.
Data were obtained from the Truth Longitudinal Cohort, a national probability-based online survey of U.S. youth and young adults (aged 15-24 years, collected from October 2022 to December 2023). The analytic sample (N=815) included participants who reported current e-cigarette use and their most important reason for e-cigarette use (selected from a list of responses, regrouped into categories), use frequency (number of days used in the past 30 days), dependence (E-cigarette Dependence Scale), and quit intentions (any versus none). Linear and logistic regression models were applied to aggregated cross-sectional data, adjusted for age, gender identity, race and ethnicity, perceived financial situation, past 30-day use of other combustible tobacco products, and e-cigarette device type.
The most endorsed reason for using e-cigarettes was coping with mental health challenges (39.6%), followed by sensation seeking (20.4%), lower perceived harms (14.7%), social status/acceptability (10.9%), ease of use/access (10.1%), and peer/family influence (4.3%). All reasons for e-cigarette use were associated with e-cigarette use frequency and dependence. Using e-cigarettes as a means of coping with mental health challenges and social status/acceptability were also associated with greater odds of expressing any quit intentions.
Reasons for e-cigarette use were differentially associated with e-cigarette use behavior outcomes. Findings suggest a need to address mental health challenges and reduce access and appeal of e-cigarettes among young people to facilitate reductions in e-cigarette use.
本研究的目的是探讨电子烟使用原因与电子烟使用频率、依赖性及戒烟意愿之间的关联。
数据来源于真相纵向队列研究，这是一项基于概率的全国性在线调查，对象为美国青少年和青年（年龄在15 - 24岁之间，于2022年10月至2023年12月收集）。分析样本（N = 815）包括报告当前使用电子烟的参与者及其使用电子烟的最重要原因（从一系列回答中选择，重新归类）、使用频率（过去30天内使用的天数）、依赖性（电子烟依赖量表）和戒烟意愿（有与无）。将线性和逻辑回归模型应用于汇总的横断面数据，并对年龄、性别认同、种族和族裔、感知的财务状况、过去30天内其他可燃烟草产品的使用情况以及电子烟设备类型进行了调整。
使用电子烟最常被认可的原因是应对心理健康挑战（39.6%），其次是寻求刺激（20.4%）、较低的感知危害（14.7%）、社会地位/可接受性（10.9%）、易用性/可及性（10.1%）以及同伴/家庭影响（4.3%）。所有电子烟使用原因均与电子烟使用频率和依赖性相关。将电子烟作为应对心理健康挑战和社会地位/可接受性的手段也与表达任何戒烟意愿的较高几率相关。
电子烟使用原因与电子烟使用行为结果存在差异关联。研究结果表明，有必要应对心理健康挑战，减少电子烟在年轻人中的可及性和吸引力，以促进电子烟使用的减少。
