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

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Associations among sexual assault, posttraumatic stress, drinking to cope with anxiety, and alcohol use based on gender identity and sexual orientation.

BACKGROUND: Sexual assault (SA) is experienced by a substantial proportion of emerging adult college students and is associated with elevated rates of posttraumatic stress disorder (PTSD) and alcohol use. This study examines the mediating role of posttraumatic stress symptoms (PTSS) in the associations among SA severity, drinking to cope with anxiety, and average weekly drinks while considering the moderating roles of gender identity and sexual orientation. METHODS: A total of 2160 college students who were diverse in gender (cisgender women, 64.4%; cisgender men, 30.6%, and transgender and gender diverse [TGD] individuals = 4.9%) and sexual orientation (heterosexual = 68.0%, LGBQ+ = 32.0%) completed measures of SA severity, PTSS, drinking to cope with anxiety motives, and average weekly drinks. RESULTS: The mediation model for the full sample indicated significant indirect effects of SA severity on drinking to cope with anxiety through PTSS, but not on average weekly drinks. Moderation analyses revealed differential relationships between the variables based on both gender identity and sexual orientation. For instance, the association between SA severity and PTSS was stronger for cisgender women and TGD individuals than cisgender men, and for LGBQ+ individuals than heterosexual individuals. While the association between PTSS and average weekly drinks was only significant for cisgender men, the association between PTSS and drinking to cope with anxiety was significant for both cisgender men and women but not TGD individuals. Furthermore, the association between SA severity and drinking to cope with anxiety was stronger for cisgender women than cisgender men. CONCLUSIONS: Findings from this study demonstrate sexual orientation and gender identity differences and similarities in the associations of SA severity, PTSS, drinking to cope with anxiety, and alcohol use. Results are discussed in relation to the self-medication hypothesis and tailoring interventions for diverse groups.

Sexual Assault Victimization: Latinx Identity as a Protective Factor for Sexual Minorities.

Sexual assault victimization is an experience that impacts many college students, and rates differ based on ethnicity and sexual minority status. However, little is known about the impact of the intersectionality of Latinx and sexual minority identities on sexual assault severity among college students. The current study examined past year sexual assault victimization severity based on sexual orientation and Latinx identities among a random sample of college students (n = 506). Further, factors associated with past year sexual assault victimization severity were examined among sexual minority participants (n = 170). Among all college students, identifying as a cisgender woman, sexual minority, or having a more severe sexual assault history was associated with higher past year sexual assault victimization severity. Further, among sexual minorities, identifying as Latinx or having fewer drinks per week were associated with less severe past year sexual assault victimization. Although preliminary, this finding suggests a need for future research to examine potential cultural factors associated with Latinx populations that may serve as protective factors for sexual assault victimization among college students.
