Reasons for E-cigarette Use, Vaping Patterns, and Cessation Behaviors among U.S. Adolescents
Menée à partir de données d'une enquête réalisée en 2020 auprès de 1 789 jeunes Américains, cette étude identifie les raisons de leur utilisation de la cigarette électronique puis examine l'association entre cette utilisation et les comportements de sevrage tabagique
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, 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 1,769 current e-cigarette users. Four main reasons for vaping were identified through factor analysis, including 1) replacing cigarettes, 2) product characteristics (e.g., flavors, concealability, and vape tricks), 3) family/friend use, and 4) curiosity. Curiosity was associated with lower odds of frequent e-cigarette use (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 reduction in youth e-cigarette use.E-cigarettes have surpassed cigarettes and become the most commonly used tobacco product by U.S. 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 (e.g., flavors, concealability, and vape tricks) was associated with more frequent e-cig use and lower odds of cessation behaviors, suggesting a need for flavor bans and product design regulation.
