Objectives: The purpose of the study is to investigate the relationship between body mass index(BMI) and periodontal disease in Korean adult from the data of the fifth Korea National Health and Nutrition Examination Survey(KNHANES). Methods: The subjects were 3,309 adults from 25 ro 45 years old in the fifth KNHANES. The subjects were divided into three BMI categories: normal weight 1,549(BMI ${\leq}22.9kg/m^2$), overweight 792(BMI $23.0-25.0kg/m^2$) and obesity 968(BMI ${\geq}25.0kg/m^2$). Periodontal disease was assessed by community periodontal index(CPI) and periodontitis was defined as ${\geq}$ code 3. Results: Increased BMI adults had no significantly higher prevalence of periodontitis than those having normal body weight after adjusting for variables; the odds ratio(OR) was 1.06 in overweight and 1.23 in obesity. BMI and periodontitis had no significant relation to increased age, but the age increase tended to have high odds ratio. Women had a higher OR than men. Conclusions: Through this study, it is necessary to analyze the relationship between the obesity index and periodontitis in the further study.
