Youth perceptions of e-cigarette-related risk of lung issues and association with e-cigarette use

E-cigarette use is associated with increased risk of negative health outcomes, including respiratory problems such as Coronavirus Disease 2019 (COVID-19). Nevertheless, adolescents and young adults (AYAs) continue to use e-cigarettes at alarming rates. We examined AYA's perceptions of the health harms of e-cigarettes in relation to respiratory problems and the associations between these perceptions and e-cigarette use.

In May 2020, we conducted an online, national cross-sectional survey of AYAs aged 13 to 24 years old (N = 4,315; 65% female; 50% ever-users, 50% never-users) to assess e-cigarette use and perceptions of the risk of respiratory problems, COVID-19, and severe lung disease for AYAs with different levels of e-cigarette use.

In comparisons between AYAs with different levels of e-cigarette use, e-cigarette-related health risk perceptions were lower among ever-users compared to never-users and among ever-users who used e-cigarettes in the past 30 days compared to ever-users who did not use in the past 30 days. After controlling for demographics, AYAs were less likely to have used in the past 30 days if they agreed that young people are at risk of respiratory problems due to e-cigarette use (adjusted Odds Ratio [aOR] = .68, 95% confidence interval [CI; .59, .78]) and e-cigarettes are harmful for their health (aOR = .52, 95% CI [.30, .90]). AYAs were more likely to have used in the past 30 days if they believed that there is no hard evidence that e-cigarette use with nicotine increases risk of severe lung disease (aOR = 1.61, 95% CI [1.42, 1.82]) and that e-cigarette use is safer than smoking cigarettes (aOR = 1.26, 95% CI [1.11, 1.42]).

Among AYAs who had ever used e-cigarettes, those who did not believe that e-cigarette use increases the risks of respiratory problems were more likely to have used e-cigarettes in the past month. To bridge the gap between youth perceptions and emerging scientific evidence on e-cigarette-related health risks, prevention messaging should seek to explain how e-cigarette use is linked to respiratory problems and could affect COVID-19 outcomes.
