Abstract

OBJECTIVES:

We investigated the prevalence and correlates of electronic cigarette (e-cigarette) use in a representative sample of Korean adults.

METHODS:

This cross-sectional study used data from the Korean National Health and Nutrition Examination Survey of 2013. We analyzed 5338 subjects (≥19 years old) who provided data on e-cigarette use, sex, age, socioeconomic status, and health risk behaviors. Multivariate analyses were performed using logistic regression.

RESULTS:

Using weighted samples, the prevalence of ever and current e-cigarette use were 6.6 and 1.1 %, respectively (11.2 and 2.0 % in men and 2.0 and 0.4 % in women). In multivariate analysis, the probability of ever e-cigarette use was highest in current smokers (OR 29.3, 95 % CI 15.5-55.3), former smokers (OR 6.1, 95 % CI 3.3-11.2), and daily heavy drinkers (OR 1.9, 95 % CI 1.1-3.4). Current e-cigarette use was associated with current smoking (OR 16.2, 95 % CI 4.7-55.4) and weekly heavy drinking (OR 2.7, 95 % CI 1.1-6.7).

CONCLUSIONS:

E-cigarette use was strongly associated with conventional cigarette use and with frequent heavy drinking. Dual use e-cigarettes and conventional cigarette use as well as the association between heavy alcohol use and e-cigarettes need further exploration.
