Abstract

Troubling disparities in viral suppression persist among transgender (trans) women living with HIV in the US. We utilized baseline data from a randomized controlled trial of a behavioral intervention among trans women living with HIV in San Francisco and Los Angeles, to identify the socio-ecological correlates of biologically confirmed viral suppression (< 200 HIV-1 RNA copies/mL). Among 253 participants, the mean age was 43 (SD = 11), 46% identified as Black or African American and 35% were virally non-suppressed. In adjusted Poisson regression models, the following barriers to viral suppression were identified: injection drug use [adjusted risk ratio (aRR) 0.78, 95% CI 0.65–0.93, Z = − 2.64, p = 0.008], methamphetamine use (aRR 0.65, 95% CI 0.51–0.83, Z = − 3.45, p = 0.001), amphetamine use (aRR 0.62, 95% CI 0.44–0.87, Z = − 2.75, p = 0.006), homelessness (aRR 0.79, 95% CI 0.63–0.98, Z = − 2.06, p = 0.039), and sex work (aRR 0.60, 95% CI 0.41–0.86, Z = − 2.77, p = 0.009). These findings underscore the importance of interventions that address the socio-ecological barriers to viral suppression among trans women in urban settings.

Resumen

Persisten disparidades preocupantes en la supresión viral entre las mujeres transgénero (trans) que viven con el VIH en los EE. UU. Utilizamos datos de referencia de un ensayo controlado aleatorizado de una intervención conductual entre mujeres trans que viven con el VIH en San Francisco y Los Ángeles, para identificar los correlatos socioecológicos de la supresión viral confirmada biológicamente (< 200 copias/ml de ARN del VIH-1). Entre 253 participantes, la edad media fue de 43 años (DE = 11), el 46% se identificó como negro o afroamericano y el 35% no tenía supresión viral. En modelos de regresión de Poisson ajustados, se identificaron las siguientes barreras para la supresión viral: uso de drogas inyectables [razón de riesgo ajustada (aRR) 0,78, IC del 95% 0,65–0,93, Z = − 2,64, p = 0,008], uso de metanfetamina (aRR 0,65, IC 95% 0,51–0,83, Z = − 3,45, p = 0,001), consumo de anfetaminas (aRR 0,62, IC 95% 0,44–0,87, Z = − 2,75, p = 0,006), falta de vivienda (aRR 0,79, IC 95% 0,63–0,98, Z = − 2,06, p = 0,039), y trabajo sexual (aRR 0,60, IC 95% 0,41–0,86, Z = − 2,77, p = 0,009). Estos hallazgos subrayan la importancia de las intervenciones que abordan las barreras socioecológicas para la supresión viral entre las mujeres trans en entornos urbanos.
