Abstract

This study investigated the association between body fatness and periodontitis. The study population comprised 6,811 individuals who participated in the United States National Health and Nutrition Examination Survey (NHANES) 2009-2012 cycles. Body adiposity was evaluated using body mass index (BMI), and visceral adiposity was evaluated using waist circumference (WC). Periodontitis was defined using two methods: the Center for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP) periodontitis case definition (CDC/AAP) and the Arbes et al. 2001 case definition (at least one site with ≥ 3 mm clinical attachment loss and ≥ 4 mm probing depth). The results showed that the prevalence of periodontitis was 41.8% according to the Arbes et al. 2001 definition and 45.7% according to the CDC/AAP definition. Based on Arbes et al. definition, those with BMI of 27-29.9 had a 34% increase in the odds of periodontitis (odds ratio (OR): 1.34, 95% confidence interval (CI): 1.08-1.66). Those who were obese (BMI ≥30) had a 47% increase in the odds of periodontitis (OR: 1.47, 95% CI: 1.22-1.76). High WC was associated with 63% higher odds of periodontal disease (OR: 1.63, 95% CI: 1.79-2.06). Based on the CDC/AAP case definition, neither high BMI nor WC were associated with periodontitis.
