- Aim: Although the association of periodontitis with body mass index (BMI)-defined
obesity has been studied, it remains controversial. Hence, this study aims to determine
whether the obesity is associated with periodontitis among Koreans and to determine
the most significant indicator of the obesity on the link.
Materials and Methods: From the Sihwa–Banwol Environmental Health Cohort,
1046 subjects 15 years of age or older were cross-sectionally surveyed. All participants
underwent periodontal and medical health examinations. Age, gender, monthly family
income, smoking, drinking, frequency of daily teeth brushing and physical activity
were evaluated through interviews. The community periodontal index (CPI) was used
to assess periodontitis. BMI, waist circumference (WC), waist hip ratio and visceral fat
area (VFA) were used to assess obesity. Multivariate linear and logistic regression
analyses were applied.
Results: BMI, WC and VFA had a dose–effect relationship with the number of
sextants with periodontitis. Although subgroup analysis revealed several significant
associations between obesity and periodontitis (CPI 3–4), the greatest association
between VFA and periodontitis was found in males, age 45–54 (odds ratio53.30;
95% confidence interval: 1.53–7.09).
Conclusions: Obesity was associated with periodontitis. VFA was the most suitable
indicator of obesity in relation to periodontitis. Obesity may be a substantial risk factor
