OBJECTIVE: To estimate the prevalence and factors associated with alcohol use among adolescents. METHODS: Population-based, cross-sectional study performed from 2005 to 2006, in the city of Pelotas, Southern Brazil, with 1,056 adolescents aged between 11 and 15 years. An anonymous, self-applied questionnaire was used, based on the World Health Organization model for drug use. Poisson regression was employed to analyze data. RESULTS: Prevalence of adolescents who reported alcoholic beverage consumption in the last month was 23.0% (95% CI: 20.4;25.4), prevalence was 21.7% among females and 24.2% among males. Prevalence of alcohol consumption at 11 years of age was 11.9%. In the multiple regression analysis, alcoholic beverage use by male adolescents was higher among those who reported tobacco use in the last month, those who were older, and those who had already had sexual intercourse. Among female adolescents, age was the only variable associated with alcoholic beverage use. CONCLUSIONS: Alcoholic beverage use was prevalent in both sexes and began at a very early age. Smoking and previous sexual intercourse were also associated with this use. Preventive measures need to begin earlier, aiming to control alcohol use in the 11-to-15-year age group.
