Abstract

Objective: The objective of the study was to assess the prevalence of oral mucosal lesions (OML) and to perform a multivariable risk assessment of demographic, socioeconomic, behavioral, and oral risk indicators for its occurrence in an urban population in South Brazil. Methods: This cross-sectional study selected 1586 subjects (719M/867F, age: 14-104years) using a multistage probability sampling strategy (65.1% response rate). Prevalence, odds ratios (OR), and confidence intervals (95% CI) were calculated accounting for the survey design. Results: Leukoplakia and lichen planus were observed in 1.01% and 1.02% of subjects, respectively. In the multivariable analysis, these lesions were significantly associated with moderate/heavy smoking (OR=9.0, 95% CI=2.1-39.1) and heavy drinking (OR=2.0, 95% CI=1.1-3.7). Candidiasis and proliferative lesions were observed in 14.09% and 3.80% of the subjects, respectively. These lesions were significantly associated with female gender (OR=2.2, 95% CI=1.5-3.2 and OR=1.7, 95% CI=1.0-2.8), older age (OR=22, 95% CI=8.0-60.8 and OR=8.9, 95% CI=3.4-23.7), and low socioeconomic status (OR=1.9, 95% CI=1.0-3.5 and OR=3.0, 95% CI=1.2-7.2). Conclusions: This population is in need of OML prevention and treatment. Future studies should validate the findings that premalignant lesions are causally related to smoking and alcohol consumption, and that other OML are associated with socioeconomic-demographic disparities in this and similar populations.
