This study sought to examine the prevalence and factors associated with youth vaping cessation behaviors.
Current (past 30-day) electronic-cigarette (e-cigarette) users from the 2020 National Youth Tobacco Survey ( = 1660, typically aged 11-18 years) were analyzed to examine the prevalence of youth intention to quit vaping, past-year quit attempts, and the frequency of quit attempts. Multivariable logistic or linear regressions were performed to assess the correlates with youth vaping cessation behaviors.
In 2020, 53.4% of current e-cigarette users reported intention to quit vaping and 67.4% reported having tried to quit vaping. Intention to quit was lower among female individuals (versus male individuals, adjusted odds ratio [aOR] = 0.7, = .0004), users of a modifiable system (versus disposable e-cigarettes, aOR = 0.4, = .0204), and dual or poly users (versus sole e-cigarette use, aOR = 0.7, = .0144). e-cigarette harm perception was positively associated with intention to quit (aOR = 2.2, < .0001) and past-year quit attempts (aOR = 1.6, = .0037). Reasons for e-cigarette use were related to cessation behaviors. Adolescents who vaped because of curiosity had higher odds of past-year quit attempts (aOR = 1.4, = .0306), whereas users to disguise vaping had a lower likelihood of intention to quit (aOR=0.4, < .0001) and past-year quit attempts (aOR = 0.7, = .0126). The average number of past-year quit attempts was 5.3, and it was lower among female individuals (versus male individuals), users of e-cigarettes with prefilled pods or cartridges (versus disposable e-cigarettes), and those with nicotine cravings (versus no nicotine craving).
Intention to quit vaping and past-year quit attempts are prevalent among US adolescent e-cigarette users. The study findings inform the development of multifaceted vaping cessation programs to take sex, e-cigarette devices, vaping reasons and patterns, harm perception, and nicotine dependence into account.
本研究旨在调查青少年电子烟戒烟行为的流行情况及其相关因素。
对2020年全国青少年烟草调查中的当前（过去30天）电子烟使用者（n = 1660，年龄通常在11 - 18岁）进行分析，以研究青少年戒烟意愿、过去一年的戒烟尝试以及戒烟尝试频率的流行情况。进行多变量逻辑回归或线性回归以评估与青少年电子烟戒烟行为的相关性。
2020年，53.4%的当前电子烟使用者表示有戒烟意愿，67.4%的使用者表示曾尝试戒烟。女性（与男性相比，调整后的优势比[aOR] = 0.7，P = .0004）、使用可改装系统的使用者（与一次性电子烟相比，aOR = 0.4，P = .0204）以及同时使用多种产品或多种电子烟的使用者（与仅使用电子烟相比，aOR = 0.7，P = .014）的戒烟意愿较低。对电子烟危害的认知与戒烟意愿（aOR = 2.2，P < .0001）和过去一年的戒烟尝试（aOR = 1.6，P = .0037）呈正相关。使用电子烟的原因与戒烟行为有关。因好奇而使用电子烟的青少年过去一年尝试戒烟的几率更高（aOR = 1.4，P = .0306），而出于掩饰目的使用电子烟的使用者戒烟意愿较低（aOR = 0.4，P < .0001）且过去一年尝试戒烟的几率较低（aOR = 0.7，P = .0126）。过去一年的平均戒烟尝试次数为次，女性（与男性相比）、使用预装烟弹或烟管的电子烟使用者（与一次性电子烟相比）以及有尼古丁渴望的使用者（与无尼古丁渴望者相比）的戒烟尝试次数较少。
美国青少年电子烟使用者中戒烟意愿和过去一年的戒烟尝试较为普遍。研究结果为制定多方面的电子烟戒烟计划提供了参考，该计划应考虑性别、电子烟设备、使用电子烟的原因和模式、对危害的认知以及尼古丁依赖等因素。
