Background: Smoking is known to increase the risk of chronic disease. Understanding of factors that contribute to smoking cessation may help to develop strategies for smoking behavior change. Methods: Pooled cross-sectional data of 11,924 subjects from the Korea National Health and Nutrition Examination Survey II-V were analyzed. The stages of change in smoking cessation were categorized into pre-contemplation, contemplation, and preparation. Baseline characteristics, socioeconomic factors, quality of life, psychological characteristics, and tobacco-related factors were compared between the groups. Results: The study population consisted of 32.4% in pre-contemplation, 54.4% incontemplation, and 13.1% in preparation group. While the proportion for pre-contemplation group (37.4% to 28.4%) tended to decrease from 2001 to 2012, that of preparation group (6.4% to 18.1%) tended to increase. The mean age of pre-contemplation group (48.4±16.2) is higher than comtemplation and preparation group (42.2±13.9 and 44.4±15.3; P=0.02). As levels of education and income status increased, the proportion of pre-contemplation tended to decrease, and that of preparation tended to increase. Proportion of blue collar job in pre-contemplation group was higher than in preparation group (67.9% vs 58.1%; P<0.001). In pre-contemplation group, percentage of suicidal ideation within 1 year was higher than contemplation and preparation group19.3% vs 16.0% and 16.1%). Upon adjusting analysis, the proportion of pre-contemplation group increased with increasing age (OR=1.01; 95%CI 1.01-1.02), and smoking amount (OR=1.04; 95%CI 1.03-1.05). People of pre-contemplation group (vs. preparation) are be less educated (OR=1.99; 95% CI 1.51-2.62), are in single marital status (OR=1.25; 95%CI 1.04-1.50), have lower prevalence of cardiovascular disease OR=0.48; 95%CI 0.31-0.76), and do less exercise walking (OR=1.36; 95%CI 1.09-1.69)and weight training (OR=1.59; 95%CI 1.35-1.85). Conclusions: We demonstrated a signifi cant association between the stages of changesmoking cessation and age, education, marital status, cardiovascular disease, and amount of exercise.
