This study sought to examine reasons for youth e-cigarette use in association with vaping patterns and cessation behaviors.
A national representative sample of current (past 30-day) e-cigarette users in grades 6-12 was analyzed using the National Youth Tobacco Survey (NYTS), conducted from January to March 2020. An exploratory oblique factor analysis using a rotated pattern matrix to select salient variable-factor relationships yielded four subscales related to reasons for youth e-cigarette use. Multivariate logistic regressions were performed to assess the associations of each subscale with vaping patterns (frequent e-cigarette use, dual use of e-cigarettes and other tobacco products) and vaping cessation behaviors (intention to quit vaping and past-year quit attempts).
The 2020 NYTS sampled 180 schools with 1769 current e-cigarette users. Four main reasons for vaping were identified through factor analysis, including (1) replacing cigarettes, (2) product characteristics [eg, flavors, concealability, and vape tricks], (3) family/friend use, and (4) curiosity. Curiosity was associated with lower odds of frequent e-cigarette use (adjusted odds ratio [AOR] = 0.5, p < .0001) and dual use of e-cigarettes and other tobacco products (AOR = 0.6, p = .01) but higher odds of intention to quit (AOR = 1.2, p = .26) and past year quit attempts (AOR =1.5, p = .01). Vaping due to product characteristics was associated with higher odds of frequent e-cigarette use (AOR = 1.7, p < .0001) and lower odds of intention to quit (AOR = 0.3, p < .0001) and past year quit attempts (AOR = 0.9, p = .01).
Adolescents vape for various reasons that follow distinct patterns and user characteristics. Overall, interventions tailored to address heterogeneous reasons for vaping may help optimize the reduction in youth e-cigarette use.
E-cigarettes have surpassed cigarettes and become the most commonly used tobacco product by US youths. Adolescents choose to vape for different reasons. This study examined reasons for youth e-cigarette use and their associations with vaping patterns and cessation behaviors. The product characteristics factor (eg, flavors, concealability, and vape tricks) was associated with more frequent e-cigarette use and lower odds of cessation behaviors, suggesting a need for flavor bans and product design regulation.
本研究旨在探讨青少年使用电子烟的原因与吸食模式和戒烟行为之间的关系。
使用全国青年烟草调查（NYTS）对目前（过去 30 天）使用电子烟的 6-12 年级学生进行全国代表性抽样分析，该调查于 2020 年 1 月至 3 月进行。采用旋转模式矩阵的探索性斜交因子分析选择与青少年使用电子烟的原因相关的显著变量因子关系，得出与青少年使用电子烟的四个主要原因相关的四个子量表。采用多元逻辑回归评估每个子量表与吸食模式（电子烟频繁使用、电子烟和其他烟草制品双重使用）和电子烟戒烟行为（戒烟意愿和过去一年戒烟尝试）的关联。
2020 年 NYTS 抽样了 180 所学校，共 1769 名目前使用电子烟的青少年。通过因子分析确定了四个主要的吸食电子烟原因，包括（1）替代香烟，（2）产品特性[例如，口味、隐蔽性和电子烟技巧]，（3）家庭/朋友使用，以及（4）好奇心。好奇心与电子烟使用频率较低的可能性相关（调整后的优势比[OR] = 0.5，p <.0001）和电子烟与其他烟草制品双重使用的可能性较低（OR = 0.6，p =.01），但与戒烟意愿（OR = 1.2，p =.26）和过去一年戒烟尝试的可能性较高（OR =1.5，p =.01）。由于产品特性而吸食电子烟与电子烟使用频率较高的可能性相关（OR = 1.7，p <.0001）和戒烟意愿较低的可能性相关（OR = 0.3，p <.0001）和过去一年戒烟尝试的可能性（OR = 0.9，p =.01）。
青少年吸食电子烟的原因各不相同，与吸食模式和用户特征有关。总体而言，针对电子烟使用的不同原因量身定制的干预措施可能有助于优化减少青少年使用电子烟的效果。
电子烟已超过香烟，成为美国青少年最常使用的烟草产品。青少年选择吸食电子烟有不同的原因。本研究检查了青少年使用电子烟的原因及其与吸食模式和戒烟行为的关系。产品特性因素（例如，口味、隐蔽性和电子烟技巧）与更频繁地吸食电子烟和戒烟行为的可能性较低有关，这表明需要禁止口味和产品设计管制。
