Abstract
INTRODUCTION: Transgender (trans) and nonbinary people (TNB) are disproportionately impacted by HIV. HIV testing is critical to engage TNB people in HIV prevention and care. Yet, scant literature has examined social and structural factors associated with HIV testing among TNB people of diverse genders and in geographies with potentially lower trans acceptance. We: (1) characterized the prevalence of never having been tested for HIV; and (2) identified associated factors, among TNB people in Michigan, United States. METHODS: Data were from a community-based participatory cross-sectional survey (n = 539 sexually experienced TNB people). The prevalence of never having had an HIV test was reported overall and compared across socio-demographic, clinical, social and structural factors using bivariable and multivariable logistic regression analyses. RESULTS AND DISCUSSION: Approximately one-quarter (26.2%) of participants had never had an HIV test (20.8% transfeminine; 30.0% transmasculine; 17.8% nonbinary assigned male at-birth; and 32.0% nonbinary assigned female at-birth). In a multivariable socio-demographic model, older age (adjusted odds ratio [aOR] for 1-year increase: 0.93, 95% CI: 0.90, 0.96, p<0.001) and Black/African American race (vs. White) (aOR: 0.28, 95% CI: 0.09, 0.86, p<0.05) were associated with increased odds of HIV testing (aORs for never testing). In separate multivariable models controlling for socio-demographics, ever experiencing sexual violence (aOR: 0.38, 95% CI: 0.21, 0.67, p<0.001), not accessed sexual/reproductive healthcare in the past 12 months (aOR: 4.46, 95% CI: 2.68, 7.43, p<0.001) and reporting a very/somewhat inclusive primary care provider (PCP) (aOR: 0.29, 95% CI: 0.17, 0.49, p<0.001) were associated with HIV testing (aORs for never testing). CONCLUSIONS: Findings contribute to scant literature about gender-based differences in HIV testing inclusive of transmasculine and nonbinary people. Lack of statistically significant gender differences suggests that broad TNB interventions may be warranted. These could include training healthcare providers in trans-inclusive practices with sexual violence survivors and PCPs in trans-inclusive HIV prevention and care. Findings showing Black participants were less likely to have never had an HIV test suggest the promise of culturally tailored services, though further investigation is needed. Findings identify social and structural factors associated with HIV testing and can inform multi-level interventions to increase TNB person's HIV testing.
