Notes. Analysis was limited to current drinkers (results for the overall sample including abstainers are available from the authors upon request). Heavy drinking was defined as 5+ drinks/day on at least 7 occasions for men, and 4+ drinks/day on at least 3 occasions for women.
PS weighting was performed to weight the White current drinker sample to be similar to Black current drinker sample on an increasing number of factors introduced at each step, with black as the reference group; factors in each step include the variables in prior steps.
The White-Black difference is calculated as the White % - the Black %.
Protective resources include proscriptive religiosity, social network drinking norms and patterns, family social support, area-level religious membership
