Patterns of alcohol use among Brazilian adolescents

Abstract

Objective: To describe patterns of alcohol consumption by adolescents in Brazil. Method: From November 2005 to April 2006, a sample composed of 661 subjects aged between 14 to 17 years was rigorously selected in Brazil using a multistage probabilistic method to represent the profile of the adolescent Brazilian population. Results: 34% of Brazilian adolescents drink alcoholic beverages. The mean age of drinking initiation was 14 years of age. Older adolescents, as well as those living in the southern part of Brazil, those who are not attending school and those who are working, and black individuals and those with personal income reported a higher frequency of drinking. Socio-demographic factors such as gender, income bracket, family income and student status do increase the amount of alcohol consumed. Males report a higher frequency of binge drinking than females. Moreover, more than half of the males that had drunk in the previous year reported having engaged in binge drinking on at least one occasion. Beer represents approximately half of all the drinks consumed by adolescents. There was no significant difference between genders in the kind of alcohol consumed. Discussion: Among adolescents who drink, the consumption of several drinks is frequent. Alcohol consumption varies from region to region, social economic status (including self-generated income) and age. These findings are discussed in light of their importance for the development of alcohol prevention policies in Brazil. Descriptors

Propaganda de álcool e associação ao consumo de cerveja por adolescentes

“…Brazil is a market with great potential for growth, due to its growing economy and large population (with a high proportion of adolescents). b The majority of Brazilian adolescents do not drink alcoholic beverages regularly, 24,c and the habits and living conditions of the population of Brazil are different from those of the countries studied. Original studies must be conducted in the Brazilian culture to evaluate the possibility of comparing this reality with data from other locations.…”

Differences in drinking patterns between men and women in Brazil

“…Most research aimed at investigating differences between men and women regarding alcohol use has targeted less representative samples, such as students 14 18,19 with a representative sample of the nationwide population. It found that 58% of Brazilians had drunk at least once in the past year, among them, 65% were men and 41% women.…”

Amphetamine, but not methylphenidate, increases ethanol intake in adolescent male, but not in female, rats

“…A study (Pinsky, Zaleski, Laranjeira, & Caetano, 2010) found that more than half of the ethanol ingested by adolescents is derived from beer, a drink containing 3%–8% ethanol. Sixty‐seven percent of adolescents aged 18–20 years who incurred in binge drinking in the United States also reported beer as their beverage of choice (Naimi, Brewer, Miller, Okoro, & Mehrotra, 2007).…”
