Abstract

Objectives: The purpose of the study is to investigate the relationship between obesity and periodontal diseases in adults. Methods: The subjects were 6,762 adults over 19 years old selected from the 6th Korean National Health and Nutrition Examination Survey(2013). The study instruments included periodontal status of periodontal diseases, body mass index(BMI), and waist circumference(WC). Periodontal status was evaluated by community periodontal index(CPI). Data were analyzed using SPSS 18.0 program. Results: The prevalence of periodontal diseases was higher in male, older aged people, undereducated people, current smokers, and those having poor cognition for toothbrushing(p<0.001). The rate of obesity by BMI and WC was higher in male, older aged people and current smokers. The rate of obesity was lower in well-educated people and good practice of toothbrushing(p<0.001). The prevalence of periodontal diseases by BMI showed 0.565 times lower in underweight population, 1.302 times higher in overweight population, and 1.311 times higher in highly obese population than normal population. The prevalence of periodontal diseases by waist circumferences showed 1.404 times higher in obese population than the normal population(p<0.05). Conclusions: It is very important to promote periodontal disease prevention and education for obese population in Korea. The risk of periodontal diseases can be preventable by decrease of BMI and WC.
