BACKGROUND: Many authors discuss factors which influence involving adolescence into alcohol use. This study was aimed to assess contribution of factors related to alcohol use in the family, getting into situations of alcohol use as well as preventive work in teenage establishments.MATERIAL AND METHODS: Survey of 373 adolescents attending teenage clubs was conducted in Kazan, Russia, with questions related to alcohol use in the family and among peers, age and circumstances of first alcohol use. The outcome measure was whether respondents were current alcohol users. Associations were explored through logistic regression models.RESULTS: Alcohol use by teenagers did not differ by gender. Odds of using alcohol increased with age (OR=1.46 95%CI 1.19-1.80 per year). Risk of alcohol use was lower if no family members used alcohol (OR=0.3 95%CI 0.2-0.5) compared to those teenagers who have any family members who used alcohol. After adding to the model variables related to the first alcohol use, most significant was association with the response that no one has ever proposed to drink alcohol (OR=0.014 95%CI 0.005-0.041) compared to any situations of alcohol use, while the association with familial factors was attenuated. This shows that impact of familial factors could be mediated through the occasions of alcohol use. Teenagers whose parents do not use alcohol less likely get into situations where they are proposed to drink in a peer group (12% vs. 24%) or at a party (18% vs. 25%).Adolescents who expressed negative attitude to alcohol-related work in youth clubs more likely were alcohol users themselves (OR=21.1 95%CI 2.6-170.3), which is better applicable for diagnostics than for program evaluation.CONCLUSION: Absence of alcohol in the family predetermines alcohol use by adolescents. Teenagers whose parents do not use alcohol less likely get into situations where they are suggested to drink alcohol.
