The Association Between Nicotine Dependence and Health Behaviors Among Adult Smokers in Korea
摘要
This study estimated the proportion of nicotine dependence among current smokers in Korea and investigated its association with health behaviors. This cross-sectional study used data from the 2016, 2019, and 2022 Korea National Health and Nutrition Examination Surveys (n = 3,003 adult current smokers). The proportion of nicotine dependence among adult Korean current smokers, defined as Heavy Smoking Index ≥ 4, was 18.0%. In comparison with smokers showing low nicotine dependence, those with high nicotine dependence were more likely to engage in high-risk alcohol consumption (aOR = 1.51, 95% CI = 1.22–1.88) and less likely to undergo general health screening (aOR = 0.72, 95% CI = 0.56–0.91). Similarly, higher nicotine dependence scores were associated with more risky alcohol consumption (p-trend < 0.001), general health screenings (p-trend = 0.002), and cancer screenings (p-trend = 0.017). Since smoking is a well-known major risk factor for diseases, a tailored health programs to encourage smoking cessation and improve health behaviors among smokers, especially those with high nicotine dependence, is essential.
