Alcohol consumption among Brazilian Adolescents according to the National Adolescent School-based Health Survey (PeNSE 2012)

Authorship SCIMAGO INSTITUTIONS RANKINGS

OBJECTIVE:

To describe the prevalence of alcohol consumption among Brazilian students and identify the sociodemographic factors associated alcohol consumption in the last 30 days.

METHODS:

Cross-sectional study with a cluster sample of 109,104 9th grade students in Brazilian public and private schools in 2012. The prevalence and 95% confidence intervals of the indicators of alcohol consumption were analyzed.

RESULTS:

Of the students analyzed, 50.3% (95%CI 49.0 - 51.6) experimented one dose of alcoholic beverages or more. The consumption of alcohol in the last 30 days was 26.1% (95%CI 24.5 - 27.7), and there was no difference in prevalence between students from public and private schools. Drunkenness episodes were reported by 21.8% (95%CI 21.1 - 22.5) of the students. The perception of students about the negative reaction of their family if they came home drunk occurred in 89,7% (95%CI 89,6 - 89,9) of cases, and 10% (95%CI 8.9 - 11.1) of them reported having problems with their families or friends because they had been drinking. Among adolescents aged less than 14 years old, the first alcoholic drink intake was predominantly at 12 to 13 years old. The most common way to get a drink was at parties, with friends, buying in them in supermarkets, stores or bars and at home. The consumption of alcohol in the last 30 days was less frequent among boys, increasing with age.

CONCLUSION:

The study demonstrates the extension of alcohol as a problem, making it important to advance in measures such as the improvement of protective legislation for children and adolescents and stricter enforcement in alcohol sales.
