Abstract

Background and Objective: An association between alcohol consumption and periodontitis has been suggested in the literature, but the evidence is still unclear. The aim of the present study was to investigate the relationship between alcohol consumption and periodontitis in a probability sample of adults from south Brazil. Material and Methods: This analysis included 1115 subjects aged 18-65 years derived from a representative sample from south Brazil. Data were collected from participants from clinical examination and structured interviews. Alcohol consumption was assessed by asking participants about the usual number of drinks consumed in a week. Four categories of alcohol consumption were defined: non-drinker, ≤ 1 glass/wk, > 1 glass/wk, ≤ 1 glass/d and > 1 glass/d. Individuals with ≥ 30% teeth with periodontal attachment loss ≥ 5 mm were classified as having periodontitis. Logistic models adjusting for age, race, socioeconomic status, dental care, body mass index, self-reported diabetes and smoking were used to estimate odds ratios (OR) and confidence intervals (95% CI). Results: After adjusting for co-factors, females who reported drinking > 1 glass/d were more likely to have periodontitis (OR = 3.8, 95% CI = 1.4-10.1), whereas females who reported drinking up to 1 glass/d were 50% less likely to have periodontitis (OR = 0.5, 95% CI = 0.3-0.8). No significant associations between overall alcohol intake and periodontitis were observed for males. In an exploratory analysis, wine consumption was associated with a lower likelihood of periodontitis among males (OR = 0.2, 95% CI = 0.1-0.5) but not females. Conclusion: The periodontal health of males and females appears to be affected differently by alcohol consumption. Moderate wine consumption may have a beneficial effect in males.
