Socio-demographic factors and risk behaviors associated with alcohol consumption: a cutout of the Erica study

ABSTRACT Alcohol use impacts morbimortality in adolescence. Thus, this study aimed at identifying the relationship between alcohol, sociodemographic variables and risk behaviors among adolescents from the city of Belo Horizonte. Descriptive analysis and association tests and logistic regression were performed based on the data from the Study of Cardiovascular Risk in Adolescents (Erica). Alcohol consumption was found in 22.1% of the adolescents. The results of the multivariate analysis revealed that not using Oral Contraceptive (OC) in the last relation increased by 3.5 times the odds of adolescents consuming alcoholic beverage (OR: 3.5 CI95% 2.49-4.91). Smoking increased the chances of teenagers making use of alcoholic beverage by 7.25 times (OR: 7.25 CI95% 3.7-14,22). Male adolescents are 1.47 times more likely to consume alcoholic beverages than girls (OR: 1.47 CI 95% 1.14-1.89). Ageing increases 1.36 times the chance of adolescents using alcohol (OR: 1.36 CI95% 22-1.51). Presenting higher value of wealth proxy increased 1.04 times the chance of adolescents consuming alcoholic beverage (OR: 1.04 95% CI 1.01-1.07). Thus, it is concluded that health actions aimed at preventing alcohol consumption among adolescents should contemplate the differences between social classes, gender and age, as well as prevention of smoking and the promotion of sexual and reproductive health.
