Abstract
Our study sought to evaluate the prevalence of binge drinking in adolescents and its association with density of alcohol outlets around schools. This cross-sectional study was conducted in Belo Horizonte, Minas Gerais State, Brazil, with 436 high-school students aged between 17 and 19 and enrolled in 18 public and private schools. The students completed the Alcohol Use Disorder Identification Test (AUDIT-C), consisting of questions about alcohol consumption by parents and siblings, and socioeconomic status (type of school, mother's education level). Data from geographic information systems were used to estimate the density of alcohol outlets around schools participating. The association between exploratory variables and binge drinking was investigated using multilevel logistic regression analysis (p < 0.05) with random intercepts and fixed slopes. A three-step sequential modeling strategy was adopted. The prevalence of binge drinking was 39.9%. The alcohol consumption among adolescents was lower for those studying in areas with low density of alcohol outlets around schools (OR = 0.32; 95%CI: 0.14; 0.73) and the consumption of alcohol by mothers was associated with binge drinking among adolescents (OR = 1.94; 95%CI: 1.14; 3.30). Our study concluded that binge drinking among adolescents was associated with density of alcohol outlets around the schools and mother's alcohol consumption.
Highlights
Adolescent binge drinking represents a public health concern capable of damaging the individual and the collective 1
The frequency of binge drinking in our study was high (39.9%), to other studies [7,9,27,31]
The prevalence of binge drinking in our study was obtained in the month [21,32], which explains the difference among a previous study that revealed a prevalence of 53% binge drinking per year among Brazilian adolescents with similar age 21
Summary
Adolescent binge drinking represents a public health concern capable of damaging the individual and the collective 1. The last national drug survey revealed that 43.6% of Brazilian adolescents between 13 to years old and 65.3% between to 18 reported having consumed alcoholic beverages in the last year 3. Poor school performance, unprotected sex and drug use are multiple risk behaviors associated with this practice [4,5,6,7]. The consumption of alcohol reflects the complex interactions of individual-level risk and protective factors with family expectation and community environment [8,9,10]. The same individual-level factors may produce differential effects when studied in distinct social contexts 11. For example, constitute important contexts in which adolescents can develop deviant behaviors such as binge drinking 12
