Objective: This cross-sectional study was performed to investigate the association between excess body weight and periodontitis in adults, stratified by sex and age, and using different criteria for obesity. Material and methods: Enrolled in the study were 345 individuals with a minimum age of 18 years who had attended the Public Health Service in the city of Salvador, Bahia, Brazil. All individuals underwent a complete periodontal examination and anthropometric measurements and answered a questionnaire regarding their socioeconomic, demographic, health, and lifestyle conditions. Excess body weight (exposure factor) was defined using body mass index (BMI) and waist circumference (WC). Prevalence ratios (PRs) and 95% confidence intervals (95%CI) were obtained by Poisson regression analysis with robust variance. Results: Periodontitis was found in 74.2% of study participants, with the disease being more prevalent among those individuals with increased WC. The occurrence of overweight was 44.4% and that of obesity ranged from 29.9 to 70.8%, dependent upon the specific definition of obesity that was used. There was a positive association between obesity (WC > 88 cm) and periodontitis only among women, after adjustment for age, smoking habit, education level, diabetes, and family income (PRadjusted: 1.20; 95%CI: [1.01–1.44]). The magnitude of this positive association was higher among women aged 18 to 49 years when the outcome was severe periodontitis, and the exposure was obesity defined by WC. Conclusions: The findings draw attention to the high frequency of the diseases investigated: overweight, obesity and periodontitis. Moreover, obesity was positively associated with periodontitis in women and younger individuals, demonstrating that among those with obesity, there is a higher probability of having periodontitis. The smaller number study of men in the may have influenced the non-statistically significant association found in that group. Clinical relevance: Obese females and younger people are more likely to also have periodontitis. Periodontal evaluation and clinical management of individuals with obesity is recommended.
