Résumé :
Background: We aimed to examine prevalence and correlates of past-month electronic cigarette (“e-cigarette”) use and use of e-cigarettes to aid a cessation attempt in three samples of young adult smokers recruited online in 2009–2010 (Study 1), 2010-2011 (Study 2), and 2013 (Study 3).
Methods: Participants were young adults aged 18 to 25 who smoked at least one cigarette in the previous month (Study 1, N = 1987 and Study 2, N = 570) or smoked 3 or more days each week and used Facebook 4 or more days per week (Study 3, N = 79). We examined both past-month e-cigarette use and ever use of e-cigarettes to quit conventional cigarettes.
Results: Prevalence of past-month use of e-cigarettes was higher in each subsequent study: Study 1 (6%), Study 2 (19%), and Study 3 (41%). In multivariate analyses, significant correlates of past-month e-cigarette use were identified for Study 1 (male sex OR = 2.1, p = .03; past-year quit attempt OR = 1.6, p = .03) and Study 2 (male sex, OR = 1.7, p = .03; younger age OR = 0.88, p = .05), but not Study 3. In multivariate analyses, significant correlates of ever use of e-cigarette to quit conventional cigarettes were identified for Study 1 (education, OR = 1.2, p = .02; smoking within 30 min of waking, OR = 2.8, p = .02; past year quit attempt OR = 4.1, p = .02), and Study 3 (desire to quit smoking, OR = 1.3, p = .02), but not Study 2.
Conclusions: E-cigarette use is increasingly common among young adults, particularly men. E-cigarette use for quitting conventional cigarettes appears more common among those more nicotine dependent and interested in quitting.
Highlights:
Analyses from three studies over five years looked at electronic cigarette use.
Young adult cigarette smokers living in the U.S. were recruited online.
Prevalence of past-month e-cigarette use was higher in each subsequent study.
Use for quitting smoking was greater among nicotine dependent and motivated to quit.
Findings increase understanding of patterns and correlated of e-cigarette use.
