Data on dietary intake, alcohol consumption, physical activity, and smoking behavior from the Thai National Health Examination Survey IV for subjects aged 15-98 years (n = 19 371) were included in the analysis. Trends between health behaviors among regular smokers, ex-smokers with different durations of smoking (< 1 year, 1-10 years, > 10 years), and never smokers were tested. Logistic regression models adjusted for sex, age, and economic status were used.
The prevalences of regular smoking, ex-smoking, and never smoking were 22.3%, 12%, and 65.7%, respectively. A trend was found for consumption of fruit, beans and meats, dairy and soy milk, whole-grain products, nutritional supplements, and eating habits. Average daily alcohol consumption (g) was lowest among ex-smokers who had quit for > 10 years ex-smokers (16.4) followed by 1-10 years ex-smokers (27.2), and < 1 year ex-smokers (33.7).
A longer duration of smoking cessation correlated with better health behaviors.
