The purpose of this study was to investigate the correlation between obesity and periodontitis by the number of pregnancy using the Korean National Health and Nutrition Examination Survey(2010-2015). Periodontitis measures the community periodontal index, and body mass index was used for the obesity. Socioeconomic variables and health-related behaviors were investigated. Periodontitis and obesity were higher in women with a high pregnancy frequency after controlling for confounding variables. In conclusion, periodontitis is closely related to obesity, and the association is somewhat higher as the number of pregnancies increases. Comprehensive management of obesity and periodontitis is effective in developing health promotion program for women in future, and this data will be used as basic data for development of women's health promotion program.
