The Impact of Secondhand Vape Exposure on Adolescents' Willingness to Try E-Cigarettes
Abstract
PURPOSE: Several factors impact the influenceability of adolescents to try electronic nicotine delivery systems; however, it is unknown how secondhand vape exposure influences their willingness to try these products. The aim of this study was to explore the impact of secondhand aerosol (SHA) exposure on willingness to try e-cigarettes among adolescents who have never vaped.
METHODS: In this observational, cross-sectional study, we used data from the National Youth Tobacco Survey from 2022 to examine the association between exposure to SHA and willingness to try e-cigarettes among adolescent never-vapers. Multiple logistic regression was used to compare the odds of being willing to try e-cigarettes among participants exposed to SHA versus those unexposed to SHA, adjusting for age, race, ethnicity, gender, and mental health symptoms, online exposure to social media e-cigarette content, other nicotine use, perceptions of harmfulness of secondhand vapor, education performance, education level and family socioeconomic status.
RESULTS: Exposure to SHA was associated with a 105% increase in the odds (odds ratio [OR] = 2.05; 95% confidence interval [CI] = 1.85-2.29) of being curious to try e-cigarettes, 75% increase in the odds (OR = 1.75; 95%: CI = 1.54-1.99) of being willing to try e-cigarettes soon, and 79% increase in the odds (OR = 1.85; 95%: CI = 1.57-2.18) of being willing to try e-cigarettes within the year.
DISCUSSION: Adolescents exposed to SHA are more likely to consider…
