[Alcohol consumption by young adults from three cities in Southern France].
OBJECTIVE
To identify potential factors of change in alcohol consumption and regional differences which could explain why and how habits are evolving.


METHODS
Four hundred and thirty three subjects aged 20 to 34 years, were recruited by random sampling in Marseilles, Montpellier and Toulouse. A quantitative food frequency questionnaire was used to collect data on alcohol consumption. A stepwise logistic regression was applied to the total sample, to the sub-sample of drinkers, and to the sub-samples of drinkers of each type of alcoholic beverage. Factors associated with each type of alcoholic consumption were analyzed by city.


RESULTS
Montpellier and Toulouse samples were pooled because of the similarity in alcoholic consumption, which was different from that in Marseilles. There are significantly more drinkers in Montpellier/Toulouse than in Marseilles (74.4% versus 53.8%; p=0.001) and also more binge drinking subjects (31.1% versus 10.3%; p=0.001). Age, tobacco, leisure physical activity are independently associated with alcoholic consumption, female sex and Marseilles, being inversely associated. These two last factors are similarly associated with binge drinking, as well as age.


CONCLUSIONS
The study of the factors for alcoholic consumption by site suggests that differences in behavior could explain these results. These distinct characteristics should be considered when implementing anti-alcoholic prevention in youth.
