Race and gender may be important considerations for recognizing alcohol related problems in Black and White young adults. This study examined the prevalence and age of onset of individual alcohol problems and alcohol problem severity across race and gender subgroups from a longitudinal study of a community sample of adolescents followed into young adulthood (N = 166; 23–29 yrs. old who were drinkers). All alcohol problems examined first occurred when subjects were in their late teens and early 20s. Drinking in hazardous situations, blackouts, and tolerance were the most common reported alcohol problems. In race and gender comparisons, more males than females experienced alcohol problems. Blacks generally had a later age of onset of alcohol problems. Multivariate regressions showed greater alcohol problem severity in males compared to females, but no significant differences between Blacks and Whites. Education, family environment and earlier alcohol use behaviors and expectancies were reliable predictors of alcohol problem severity in young adulthood. White males were at particular risk for experiencing more severe alcohol problems. Findings may inform the design of more targeted interventions for alcohol problems in different populations.
