Results: The preventive program was associated with a decreased risk of reporting alcohol-related problems
(OR .78, 95% confidence intervals [CI] .63–.98), although this reduction was not statistically significant in
the subgroup of 743 current drinkers at baseline. The risk for alcohol consumption was not modified by
exposure to the program (OR .93, 95% CI .79 –1.09). In the intervention group, nondrinkers and occasional
drinkers at baseline progressed toward frequent drinking less often than in the control group
