Associations of home and workplace vaping restrictions with e-cigarette use among U.S. adults
Menée aux Etats-Unis en 2018 par enquête auprès de 46 751 adultes (âge : au moins 18 ans ; 52 % de femmes), cette étude analyse l'effet, sur l'utilisation de la cigarette électronique et sur l'exposition aux aérosols environnementaux, de restrictions contre le vapotage au domicile ou sur le lieu de travail
The current study examined home and workplace vaping restrictions and their associations with e-cigarette use, frequency of e-cigarette use, and exposure to environmental vape aerosol among adults in the U.S. We used the 2018 Tobacco Use Supplement to the Current Population Survey to examine current e-cigarette use, vaping frequency, and exposure to workplace environmental vape aerosol in the association with home and workplace e-cigarette restrictions, using multivariable logistic and zero-inflated Poisson regression. Of 46,751 participants, 2.1% currently used e-cigarettes, and 89% restricted home vaping. Of 19,091 working participants, 83% had worksite vaping restrictions, and 6% reported environmental vapor exposure. Respondents with household vaping restrictions had lower odds of current e-cigarette use (full ban: aOR: 0.07, 95% CI: 0.05–0.09; Partial ban: aOR: 0.51, 95% CI: 0.40–0.66). The expected number of days of past-month e-cigarette use for those with some household vaping restrictions was significantly fewer than for those without restrictions (full ban: IRR: 0.92, 95% CI: 0.85–0.99; partial ban, IRR: 0.89, 95% CI: 0.81–0.97). Workers with full workplace vaping restrictions had lower odds of workplace environmental vape aerosol exposure than those without a restriction (aOR: 0.21, 95% CI: 0.17–0.25). Vaping restrictions in homes were associated with lower prevalence and frequency of e-cigarette use. Those in worksites with complete vaping bans were less likely to be exposed to environmental aerosol at work. The home e-cigarette restrictions appear to have a stronger association with e-cigarette use behaviors than workplace restrictions.
