Table 3 describes results of additional trend analyses with the age-by-gender groups further divided into racial/ethnic categories. For these analyses, the 12–14 and 15–17 year age categories were combined. This was because of low rates of binge drinking among some groups in this age range, (particularly minority women), and because trends in Table 3 were similar for these two age categories. Among men, there was only one trend that exhibited significant differences by race/ethnicity: Among 21–23 year olds, the relative risk for binge drinking among Black men has increased since 1979 (OR=1.025 per year; 95% CI: 1.006, 1.045, p=0.01), while other groups were unchanged. Among women, however, there were several trends that differed by race/ethnicity. Significant increases in odds ratios were observed for 12–17 year old Black and Hispanic females, and for 18–20 year old Black females, but not for White females in either age category. In addition, increases in risk among minority women ages 21–23 exhibited larger trends than those for Whites (see Table 3). Minority females exhibited substantially lower rates of binge drinking than Whites in earlier survey years, but these trends suggest that this gap has narrowed somewhat over the past three decades.
