Exposure to Secondhand Aerosol From Electronic Cigarettes Among US Youth From 2015 to 2018

Menée aux Etats-Unis à partir de données d'enquêtes 2015-2018 portant sur 17 711 collégiens ou lycéens, cette étude évalue l'exposition passive des adolescents aux aérosols des cigarettes électroniques puis analyse l'association entre cette exposition et la sensibilité au tabagisme chez les non fumeurs

Résumé en anglais

The prevalence of current electronic cigarette use among US high school students increased dramatically from 11.7% in 2017 to 20.8% in 2018. Exposure to secondhand aerosol (SHA) from e-cigarettes is not harmless, as e-cigarette aerosol contains nicotine and potentially harmful substances, including carbonyl compounds, tobacco-specific nitrosamines, heavy metals, and glycols. E-cigarette use may serve as a gateway to cigarette initiation, and e-cigarette makers have significantly increased their advertising expenditures in recent years. Exposure to SHA may increase the curiosity about e-cigarettes and perceived pervasiveness of e-cigarette marketing and further elevate the susceptibility of tobacco use among never tobacco users. This study reports the trends in self-reported SHA exposure among US adolescents and examined the associations between SHA, susceptibility to tobacco use, and exposure to e-cigarette marketing among never tobacco users.
