Department of Health and Kinesiology Faculty Publications

Purpose

We examined whether workplace and hospitality vape-free air law (VAL) population coverage was associated with adolescent e-cigarette use and related disparities in the United States.

Methods

We analyzed associations between county-level workplace and hospitality VAL coverage (100% vs. < 100%) and current e-cigarette use (2014–2022) and first e-cigarette initiation (2015–2022) among US 8th, 10th, and 12th graders using nationally representative, cross-sectional Monitoring the Future data. We implemented weighted, grade-stratified, modified Poisson regression models, adjusted for individual-, county-, and state-level confounding factors, examining disparities by sex, race and ethnicity, parental education, and college educational expectations through two-way interactions.

Results

Workplace and hospitality VAL coverage was not associated with adolescent e-cigarette use or initiation overall. However, we did find that VAL coverage was associated with lower current e-cigarette use in some sociodemographic subgroups. Full (100%) hospitality VAL coverage was linked to lower e-cigarette use among male 8th and 12th graders, 12th graders with parents without a bachelor's degree, Hispanic 8th …
