The amount of alcohol intake and some associated factors in a representative sample of 691 French boys aged 13-18

As a first step in a longitudinal study, we studied a sample of 691 French boys selected at random so that the region, the type of dwelling, and the profession of the wage-earner agreed with the latest official census. About 200 questions were asked by professional interviewers. The amount of alcohol intake was calculated from questions concerning type and amount of drinks consumed on all possible occasions. The mean yearly alcohol consumption was 0.91 liters of pure ethanol at 13-14 years, 2.08 at 15-16, and 5.88 at 17-18 (national average in Frenchmen 15 years and over: 16.5). Alcohol intake increases significantly with frequency of café and public dance attendance in all three age groups. Other factors, such as cigarette smoking, pop concerts or night club attendance, familial environment, show significant difference in only one or two age groups. Type of habitation, number of siblings, church attendance, etc., are not significant.
