Abstract

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.
