Abstract
AIM: There is limited evidence of the association between dual tobacco-e-cigarette use and health-related variables in Korea. Thus, this study aimed to investigate the associations between types of cigarette smoking, sleep duration, physical activity and depressive symptoms among Korean adults. DESIGN: A cross-sectional study design using the 2019 Korean Community Health Survey. METHODS: The study subjects consisted of 179,004 adults older than 40 years from a total of 229,099 individuals. Self-reported general characteristics, smoking history, sleep duration, physical activity and depressive symptoms were analysed. RESULTS: In multinomial logistic regression, dual users of tobacco cigarettes and e-cigarettes were more likely to have sleep duration of less than 7 h per day and to report both mild and moderate-to-severe depressive symptoms than non-smokers. Single use of either cigarettes or e-cigarettes increased the risk of short sleep duration and moderate-to-severe depressive symptoms.
