Abstract

AIMS:

To examine bi-directional associations between self-reported exposure to electronic nicotine delivery system (ENDS) marketing and ENDS use, over four six-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, USA.

SETTING AND PARTICIPANTS:

Participants were 5,478 students from 24 2-year and 4-year Texas colleges. About 64% (n=3,506) 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 six 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 bi-directional 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=.07-.10, p<.001). ENDS use at waves 2 and 3 predicted self-reported exposure to ENDS marketing at wave 3 and 4, respectively (β=.07-.09, p<.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 bi-directionally associated with past 30-day use of ENDS among young adult college students in Texas, USA from 2014/2015 to 2016.
