The purpose of this study was to investigate the distribution of obesity indices and health-related quality of life index according to current smoking status and lifetime pack-years of smoking among Korean men aged ≥19 years using data from the fourth (2007-2009) and fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES). We also examined whether smoking is actually associated with obesity, abdominal obesity, and impaired health-related quality of life. Using anthropometric measurements measured in the health examination, obesity was defined as body mass index (BMI) of ≥25kg/m² and abdominal obesity was defined as waist circumference of≥90cm. The health-related quality of life was assessed using the EuroQol-5 dimension (EQ-5D) and EuroQol-Visual Analogue Scale (EQ-VAS) and the lowest (5th) quintile of the EQ-5D index scores or EQ-VAS scores was determined to have a poor healthrelated quality of life. A total of 13,880 men, 3069 (23.6%) were non-smokers, 4864 (29.4%) were former smokers, and 5947 (47.0%) were current smokers. Obesity-related indices and health-related quality of life index were generally better in non-smokers than in former and current smokers. Multivariate-adjusted odds ratios (ORs) of abdominal obesity were significantly increased in past and current smokers compared to non-smokers. The odds ratio of overall obesity defined by the BMI was increased in former smokers who quit smoking compared to non-smokers, but current smokers did not show any difference. The OR for impaired health-related quality of life for current smokers compared to non-smokers was higher for the EQ-VAS scores. However, former smokers were not associated with impaired health-related quality of life. There were also trend of increasing ORs for obesity, abdominal obesity, and impaired health-related quality of life with increasing pack-years of smoking. In conclusion, smoking was associated with metabolically adverse abdominal obesity. Also, continuing smoking has been shown to have impaired health-related quality of life. Therefore, smoking prevention and smoking cessation should be addressed as important public health issues in the prevention of smoking- and obesity-related complications and improvement of health-related quality of life.
