Binge drinking and associated factors among adolescents in a city in southeastern Brazil: a longitudinal study

Abstract

The aim of this study was to investigate changes in the frequency of binge drinking and associated factors in the city of Belo Horizonte, Minas Gerais State, Brazil. The sample consisted of 436 adolescents. Data collection involved the Alcohol Use Disorders Identification Test and the Alcohol, Smoking and Substance Involvement Screening Test. Ordinal logistic regression was used in the multivariate analysis. An increase in the frequency of binge drinking was found among adolescents who lived in areas of greater social vulnerability (OR = 1.64; 95% CI: 1.01-2.68), those whose mothers consumed alcoholic beverages (OR = 1.75; 95% CI: 1.05-2.92), those whose fathers consumed alcoholic beverages (OR = 2.02; 95% CI: 1.11-3.68), those with an increased risk of tobacco use (OR = 2.82; 95% CI: 1.07-7.42) and those who attended religious services (OR = 2.10; 95% CI: 1.30-3.38). Knowledge regarding factors associated with a change in the frequency of binge drinking among adolescents can assist in the establishment of public policies directed at health promotion and the prevention of adverse health conditions.
