Prevalence of sexually transmitted infections among transgender women living with and without HIV in the eastern and southern United States

Abstract

Background: Data on the epidemiology of sexually transmitted infections (STIs) among transgender women (TGW) with and without HIV are limited.

Methods: We analyzed baseline data collected from a cohort of adult TGW across 6 eastern and southern US cities between March 2018-August 2020 (n = 1,018). Participants completed oral HIV screening, provided self-collected rectal and urogenital specimens for chlamydia and gonorrhea testing, and provided sera specimens for syphilis testing. We assessed associations with ≥1 prevalent bacterial STI using modified Poisson regression.

Results: Bacterial STI prevalence was high and differed by HIV status: 32% among TGW with HIV and 11% among those without HIV (demographic-adjusted prevalence ratio = 1.91 [95%CI = 1.39-2.62]). Among TGW without HIV, bacterial STI prevalence differed by geographic region, race and ethnicity, and gender identity, and was positively associated with reporting >1 sexual partner, hazardous alcohol use, homelessness, having safety concerns regarding transit to healthcare, and no prior receipt of gender-affirming health services. Among TGW with HIV, older age was inversely associated with bacterial STI.

Conclusions: TGW had a high prevalence of bacterial STIs. The prevalence and correlates of bacterial STI differed by HIV status, highlighting the unique needs and risks of TGW with and without HIV. Tailored interventions may reduce sexual health-related inequities.
