Trends in exposure to and perceptions of e-cigarette marketing among youth in England, Canada and the United States between 2017 and 2019.

ABSTRACT

E-Cigarette marketing may influence e-cigarette use among youth. This study examined reported exposure to and perceptions of e-cigarette marketing among youth between 2017 and 2019 across countries with varying e-cigarette marketing restrictions. Cross-sectional online surveys were conducted with 35 490 youth aged 16-19 from England, Canada and the United States in 2017, 2018 and 2019. Weighted logistic regression models examined trends in the adjusted prevalence of self-reported exposure to e-cigarette marketing and the perceived appeal of e-cigarette ads between 2017 and 2019, by country and by smoking/vaping status. Reports of frequent exposure to e-cigarette marketing increased between 2017 and 2019 in all countries, but less so in England, where e-cigarette marketing is more restricted. Perceiving e-cigarette marketing as appealing increased from 2017 to 2019 in Canada and the United States, but not in England. In England, exposure to e-cigarette marketing did not increase in prohibited channels between 2017 and 2019. Between 2017 and 2019, never-users' reports increased for exposure to and appeal of e-cigarette marketing. The results suggest some effectiveness of e-cigarette marketing bans in England and receptivity to e-cigarette marketing among youth never users.
