Consequences of alcohol use, mean (SD)b0.09 (0.41)0.08 (0.38)0.11 (0.44)
  • a Alcohol use by student gender was significant for past 30-days use of beer, lifetime binging with beer, and past 30- days binging with beer (all χ2(7) > 14.07, P < .05), but all other comparisons of alcohol use by student gender were nonsignificant (all P > .05).

  • b Consequences of alcohol use differed by gender (t[2648] = –2.15, P < .05); P = proportion.
