Intention to quit tobacco use within 1 month according to tobacco product use patterns among Korean adult men: Korea National Health and Nutrition Examination Survey, 2019-2022

Novel tobacco products (NTPs), including heated tobacco products (HTPs) and liquid-type e-cigarettes, are widely used in Korea, but their relationship with cessation intentions remains unclear. We examined cross-sectional associations between tobacco product use patterns and intention to quit tobacco use within 1 month among Korean adult men. We used Korea National Health and Nutrition Examination Survey data (2019-2022) to analyze 3,218 men aged ≥19 years who currently used tobacco products. The primary analysis compared NTP users with conventional cigarette-only users; secondary analyses examined 7 mutually exclusive use patterns. We estimated associations using survey-weighted logistic regression, adjusting for age, education level, household income, residential area, binge drinking, aerobic physical activity, perceived stress, and survey year. NTP use was associated with lower odds of intending to quit tobacco use within 1 month (adjusted odds ratio [aOR], 0.586; 95% confidence interval, 0.443-0.774; weighted prevalence, 12.1% vs. 18.0%). Across the 7 use patterns, adjusted estimates were below 1 for every NTP-containing pattern (aOR range, 0.387-0.677; global P = 0.020). Among Korean adult men who currently used tobacco products, NTP use was associated with lower odds of intending to quit tobacco use within 1 month. Cessation counseling and support services should give attention to users of HTPs and liquid-type e-cigarettes.
