Methods : This study was carried out on 475 individuals who visited the Health Promotion Center in Youngnam University Hospital in May, 1999. The subjects were checked on age, sex, life style (smoking, drinking, physical activity, exercise, etc.), past medical history, blood pressure, height, weight, waist circumference, hip circumference, body fat percent and other obesity indexes.

Results : In men, waist circumference(P<0.01), body fat percent (P<0.05), waist hip ratio (P<0.01) were significantly increased according to the amount of smoking after adjustment for BMI, age, alcohol intake, exercise and physical activity. But, the waist circumference, waist to hip ratio and percent body fat of mild smoker were rather shorter than that of the non-smoker or on who abstained from smoking.

Conclusion : In men, it seems that obesity index of abdominal fatness may be significantly high in moderate to heavy smokers and low in mild smokers.
