[Alcohol consumption patterns in adolescence].

This study analyses alcohol consumption patterns and the role of social influence and risk perception of this substance on its consumption, in a sample of 1,624 secondary school students from Girona aged between 12 and 18 years (49.4% boys). The results show that 20.9% of the teenagers consider themselves regular alcohol consumers and that consumption increases with age, regardless of gender. A high percentage of consumers overcomes the high-risk health threshold, mainly amongst girls because of the gender differences in the metabolism of alcohol. Moreover, the influence of the social environment (friends and family) and risk perception of alcohol both on consumption and high-risk consumption is confirmed.
