Aim The aim of this study was to assess the effect of overweight and obesity on periodontal attachment loss ( PAL ) progression in an urban population from south Brazil. Methods In 2001, a population‐based oral health survey entitled “Epidemiology of periodontal diseases: the Porto Alegre Study” was conducted by drawing a probabilistic sample of 1586 individuals. After 5 years, 755 (participation rate: 47.6%) individuals were re‐examined. For this analysis, self‐reported diabetics, underweight individuals, and individuals with <6 teeth were excluded. Poisson regressions were used to calculate relative risks ( RR ) and 95% confidence intervals ( CI ) adjusted for sex, age, skin colour, education, socio‐economic status, smoking and dental care. Results Five hundred and eighty‐two individuals (333 males/249 females, 36.02 ± 14.97 years) were included. Overall, obese individuals had significantly higher risk of experiencing PAL progression than individuals with normal weight after adjusting for important co‐factors ( RR = 1.36, 95% CI = 1.04–1.78). In a stratified analysis, no statistically significant associations were observed between PAL progression and obesity for males ( RR = 1.13, 95% CI = 0.75–1.69), whereas obese females were at statistically significant higher risk than normal weight females ( RR = 1.64, 95% CI = 1.11–2.43). Conclusion Obesity appears to be a risk factor for PAL progression for females but not males in this developing country population.
