The association between alcohol use and sexual assault victimization among college students differs by gender...

Alcohol use and sexual assault (SA) are common on college campuses. The purpose of this study is to examine if the association between alcohol use and SA differs by gender identity, sexual orientation, race, or ethnicity.

A total of 3,243 college students aged 18-25 at two large, minority-serving, public universities in the southwest and southeast United States completed an online survey about alcohol and sexual behaviors. Two negative binomial regressions were conducted to examine main effects and interaction effects.

Almost half of the sample reported a SA victimization history. The main effects negative binomial regression indicated that more drinks per week, older age, identifying as a cisgender woman (vs. cisgender man), identifying as a gender minority (vs. cisgender man), and identifying as a sexual minority (vs. heterosexual) were associated with more severe SA victimization. Participants who identified as Latine (vs. non-Latine White) reported less severe SA. The negative binomial regression assessing interactions indicated that the association between alcohol use and SA severity was stronger among cisgender women and gender minority identities than cisgender men, and Black identities than non-Latine White identities.

Findings suggests that alcohol use is an important factor for SA severity among all students, but that the association is stronger among some with marginalized identities. Given that perpetrators target people who hold some marginalized identities, prevention programming could address cisnormative, heteronormative, and White normative ideas about alcohol and sex to attain social justice and health equity.
