[Factors associated with alcohol consumption in the youth of the province of Brescia].
We investigated factors related to adolescent alcohol consumption by administering an anonymous questionnaire to 2737 9th and 13th grade high-school students in the province of Brescia. A total of 1364 students coming from an urban area (the town of Brescia with about 200,000 inhabitants) and 1373 students from a mountainous area (Breno, Local Health Unit N. 37 in the Lombardy Region with 83,000 inhabitants) were interviewed. The associations between alcohol drinking and some demographic, socio-economic, behavioural and environmental variables were assessed by computing the correspective odds ratios (OR) by fitting logistic regression models for ordinal response variables ("cumulative odds" models). The results showed that the following variables were positively associated with alcohol consumption: 1) residence in a mountainous area, especially as regards spirits consumption; 2) experimental and regular smoking; 3) peer alcohol drinking (best friend and partner). Parents' daily alcohol consumption was associated with wine drinking, but not with either spirits consumption or frequency of drunkenness among students. A slight inverse relationship was also found between students' alcohol intake and their knowledge of the health hazards of alcohol, but it was not significant for all groups of students.
