 Abstract
Background: As the risks of second-hand smoke have been proven, smoke-free policies have been strengthened. In Korea, all kinds of tobacco products including combustible cigarettes, heated tobacco products, and e-cigarettes are subject to smoke-free policies. Because use of tobacco products in smoke-free areas can cause health problems, examining stealth use of tobacco products and its associated factors is needed.
Methods: The study participants comprised 25,266 adults aged 19 years and older who were current tobacco product users and clearly aware of smoke-free areas from Community Health Survey, 2019. The chi-squared test and multivariate logistic regression analysis were performed to estimate associated factors with stealth use of tobacco products including socioeconomic status, tobacco products, and awareness of smoke-free policies.
Results: Out of 25,266 participants, 5,623 (23.3%) had used tobacco products in smoke-free areas in the past year. Stealth use was more prevalent in the younger age group than the older one (OR 1.24, 95% CI 1.08-1.42), male than female (OR 1.43, 95% CI 1.24-1.65), manual workers than non-manual workers (OR 1.15, 95% CI 1.05-1.26), and never married group than married one (OR 1.22, 95% CI 1.11-1.35). Users of triple or double tobacco products including combustible cigarettes tended to violate smoke-free policies more often than those who smoke combustible cigarettes only (In triple users, OR 1.49, 95% CI 1.20-1.83).
Conclusion: To reduce stealth use, it is needed to strengthen and promote smoke-free policies.
