Risky Alcohol Use Among University Students: Associated Factors and Changes Over a Decade

To assess the prevalence and correlates of risky alcohol use among Brazilian university students and compare findings across a 12-year interval.

A questionnaire survey conducted in 2018 among a representative sample of students at the State University of Campinas. Alcohol use patterns were assessed using the Alcohol Use Disorders Identification Test, and associations with sociodemographic, academic, and mental health variables were analyzed. A bivariate analysis with a 1% significance level and multiple logistic regression with a 5% significance level were performed.

A total of 6725 university students were evaluated regarding their alcohol consumption, 34.5% of which presenting risky alcohol use. Alcohol consumption was associated with being male, single, from a higher socioeconomic status, and living with peers. Significant associations were found between risky drinking and academic difficulties, risky behaviors, and mental health problems. The comparative analyses (2006/2018) showed an increase, particularly among women, in risk (20.1% x 34.7%), high-risk drinking (3.6% x 7.6%), and probable alcohol use disorder (1.1% x 2.9%), as well as an increase in the rates of sexual intercourse while intoxicated.

High rates of risky alcohol use, particularly among women, highlight the importance of integrating individual support with population-level education and awareness initiatives.
