Objectives: This study seeks to describe the population of college students with same-sex sexual experience and determine if these students report more substance use than their peers with only opposite-sex experience. Methods: Questionnaires were completed by a national random sample of college students on 119 campuses in 1999. A total of 10,301 sexually active students were categorized as having only opposite-sex, only same-sex, or both-sex partners, and their smoking, binge drinking, and marijuana use behaviors were compared. Results: Students who report same-sex sexual experiences comprise 6.1% of respondent. Women with both-sex partners were approximately twice as likely to smoke, binge drink, and use marijuana as women with only opposite-sex partners (OR = 1.41–2.78), but women with only same-sex partners were not at increased risk for these
behaviors. Men with both-sex partners were less likely to binge drink (OR = 0.54) than men with only opposite-sex partners. Conclusions: Students with same-sex experience are present at every type of college. College women with both-sex partners appear to be an appropriate target for health interventions; outreach to these students and further study of related behaviors are warranted.
