|Electronic Cigarette Use Among Korean Adolescents: A Cross-Sectional Study of Market Penetration, Dual Use, and Relationship to Quit Attempts and Former Smoking|
|Purpose: As elsewhere, in South Korea electronic cigarettes (e-cigarettes) are marketed, in part, as
a smoking cessation aid. We assessed the prevalence of e-cigarette use among Korean adolescents
and the relationship between e-cigarette use and current (past 30-day) smoking, cigarettes/day,
attempts to quit conventional cigarettes, and ceasing to use cigarettes.
Methods: Data from the 2011 Korean Youth Risk Behavior Web-based Survey of 75,643 students
aged 13e18 years were analyzed with logistic regression.
Results: A total of 9.4% (8.0% everedual userswhowere concurrently using e-cigarettes and smoking
conventional cigarettes and 1.4% everee-cigarette only users) of Korean adolescents have ever used
e-cigarettes and 4.7% were current (past 30-day) e-cigarette users (3.6% dual users and 1.1% ecigarettes
only). After adjusting for demographics, current cigarette smokers were much more likely
to use e-cigarettes than were nonsmokers. Among current cigarette smokers, those who smoked
more frequently were more likely to be current e-cigarette users. The odds of being an e-cigarette
user were 1.58 times (95% confidence interval, 1.39e1.79) higher among students who had made an
attempt to quit than for those who had not. It was rare for students no longer using cigarettes to be
among current e-cigarette users (odds ratio, .10; confidence interval, .09e.12).
Conclusions: Some Korean adolescents may be responding to advertising claims that e-cigarettes
are a cessation aid: those who had made an attempt to quit were more likely to use e-cigarettes
but less likely to no longer use cigarettes. E-cigarette use was strongly associated with current and
heavier cigarette smoking.
