"Analyses based on the question ascertaining sexual identity indicated that nationwide, the prevalence of current alcohol use was 29.7% among heterosexual students; 37.4% among gay, lesbian, and bisexual students; and 21.5% among not sure students (Supplementary Table 98). The prevalence of current alcohol use was higher among heterosexual (29.7%) and gay, lesbian, and bisexual (37.4%) than not sure (21.5%) students and higher among gay, lesbian, and bisexual (37.4%) than heterosexual (29.7%) students. Among female students, the prevalence was higher among heterosexual (32.2%) and lesbian and bisexual (39.9%) than not sure (20.6%) students and higher among lesbian and bisexual (39.9%) than heterosexual (32.2%) students. The prevalence also was higher among heterosexual female (32.2%) than heterosexual male (27.7%) students and higher among lesbian and bisexual female (39.9%) than gay and bisexual male (29.5%) students."
