OBJECTIVES: The study aimed to describe the prevalence of alcohol use disorders in an adult population from Brazil and its association with demographic, socioeconomic, behavioral variables and health conditions. METHODS: A population-based cross-sectional survey was conducted with adults (20 to 59 years) of a medium-sized city in Southern Brazil with a random sample of 1,720 individuals. Cluster sampling was done in two stages: census tract first and household second. Alcohol use disorders were measured using the Alcohol Use Disorders Identification Test (AUDIT) and associations were tested with selected variables by Poisson Regression. Results of multivariate analysis were expressed as prevalence ratios. RESULTS: The prevalence of alcohol use disorders in the population was 18.4% (95% CI: 16.6% - 20.3%), higher among men (29.9%) than in women (9.3%). The prevalence of abstinence was 30.6%; 6.8% of respondents had already caused problems to themselves or to others after drinking; and 10.3% reported that a relative, friend or doctor had already shown concern on their drinking. After multivariate analysis, an association with alcohol use disorders remained for: being male, age 20 to 29 years, being single, declaring to be light-skinned blacks and being an ex-smoker or current smoker. CONCLUSION: The prevalence of alcohol use disorders identified is high compared with other similar studies, with differences according to being male, age 20 to 29, skin color and tobacco use. These issues must be considered in formulating public health policies aimed at reducing problems related to alcohol use.
