Abstract
To investigate the association between the alcohol outlet density in residential areas and the current and lifetime alcohol consumption, adjusted for individual and family factors. Information from a three-stage household stratified probabilistic cluster sampling survey (census tract, household, adult and adolescent), conducted in Belo Horizonte, Brazil ("Health in BH", 2008-2009) and data of the establishments were obtained from official sources and subsequently georeferenced. The outcome was the adolescents' report of current and lifetime alcohol consumption. The exposure variable was the alcohol outlet density, defined as the number of establishments within a 200-meter range from the adolescents' residence. The association was estimated by Poisson regression adjusted by individual and family variables. In total, 601 adolescents aged 14 to 17 years were included in this study. Of these, 53.3% were males and 71.0% lived in a family with income up to five minimum wages. The prevalence of lifetime alcohol consumption was 57.0% (95%CI 51.5 - 62.6) and the current was 11.9% (95%CI 8.7 - 15.0). The multivariate analysis showed a significant association between current alcohol consumption and density of snack bars (PR = 1.13; 95%CI 1.03 - 1.24), bars (PR = 1.21; 95CI% 1.05 - 1.38), and restaurants (PR = 1.11; 95%CI 1.02 - 1.21). Significant interactions between density of establishments with sex and age were found. Current alcohol consumption may be enhanced by the availability of some types of establishments located within a range of 200 meters from the adolescents' residence.
Highlights
Alcohol is considered a psychoactive substance and its abuse can be identified as one of the main risk factors for populational health
In 2016, it was the cause of 5.3% of all deaths worldwide, overcoming diseases such as tuberculosis, human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), and diabetes[1]
The sample of this study was composed of 601 adolescents, being 53.3% males; 55.4% aged 14 to 15 years, and 71% living in households whose family income was up to five minimum wages
Summary
Alcohol is considered a psychoactive substance and its abuse can be identified as one of the main risk factors for populational health. Policies aimed at regulating alcohol consumption have improved globally, but still do not provide populations with effective protection against the damage caused by alcohol[1]. About 2.3 billion people in the world currently drink alcohol. In the case of adolescents – individuals aged 10 to 19 years2 – it can reach 26.5% among the aged 15 to 19 years[1]. Adolescents find little difficulty in accessing this substance[3]. Facilitators are often related to individual and family characteristics[4,5], as well as to the characteristics of the environment in which they operate[6,7]
