Abstract

Abstract: Aims: To examine bidirectional associations between self‐reported exposure to electronic nicotine delivery system (ENDS) marketing and ENDS use, over four 6‐month follow‐up surveys, among young adults. Design: The Marketing and Promotions Across Colleges in Texas project (M‐PACT) is a cohort study that examined exposure to tobacco marketing and tobacco use behaviors among college students in Texas, United States. Setting and participants: Participants were 5478 students from 24 2‐year and 4‐year Texas colleges. Approximately 64% ( n = 3506) of the cohort were non‐white, 64% were female and the average age was 20 years. Measurements: Students completed a baseline survey in Fall 2014/Spring 2015 and three subsequent surveys 6 months apart. Items assessed current ENDS use and self‐reported exposure to ENDS marketing through the point‐of‐sale, on television, on the radio, on the internet and on billboards. A multi‐level cross‐lagged path model was used to examine the bidirectional associations between self‐reported exposure to ENDS marketing and current ENDS use across the four waves, controlling for socio‐demographics. Findings: Self‐reported exposure to ENDS marketing at each previous wave predicted ENDS use at each subsequent wave (β = 0.07–0.10, P < 0.001). ENDS use at waves 2 and 3 predicted self‐reported exposure to ENDS marketing at wave 3 and 4, respectively (β = 0.07–0.09, P < 0.001). Although ENDS users were more likely than non‐users to report exposure to ENDS marketing, self‐reported exposure to ENDS marketing predicted subsequent ENDS use controlling for prior ENDS use. Conclusion: Self‐reported exposure to electronic nicotine delivery system (ENDS) marketing was bidirectionally associated with past 30‐day use of ENDS among young adult college students in Texas, USA from 2014/15 to 2016.
