Personalized Cognitive Counseling Reduces Drinking Expectancy Among Men Who Have Sex with Men and Transgender Women in Lima, Peru: A Pilot Randomized Controlled Trial.

Personalized cognitive counseling (PCC) is an evidence-based intervention designed to modify HIV-related risk behavior. We assessed the impact of PCC on sexual behavior, drinking expectancy, and incidence of sexually transmitted infections (STIs) in a 6-month randomized controlled trial among 153 HIV-uninfected men who have sex with men (MSM) and transgender women (TW) in Peru. Study retention was ≥ 90%, with three HIV infections (3 Control) and 19 cases of GC/CT (10 Control, 9 PCC) at 6 months. There was a decline in condomless receptive anal intercourse in the Control (0.74, 95% CI 0.60-0.91; p < 0.01) and PCC arms (0.72, 0.55-0.94; p = 0.02) at 6-month follow-up. There was a decrease in drinking expectancy at 6 months among participants endorsing alcohol use in the PCC arm (0.89, 0.83-0.96; p < 0.01), versus no change in the Control arm (0.98, 0.92-1.04; p = 0.54). PCC was efficacious in reducing drinking expectancy and HIV risk among MSM and TW in Peru.

RESUMEN: La consejería cognitiva personalizada (CCP) es una intervención basada en evidencia diseñada para poder modificar el comportamiento asociado con el riesgo de contraer VIH. Evaluamos el impacto de CCP en el compartimiento sexual, el drinking expectancy, y la incidencia de infecciones de transmisión sexual (ITS) a través de un estudio controlado aleatorio que duró seis meses e incluyó 153 hombres sin VIH que tienen relaciones sexuales con hombres (HSH) y mujeres transgéneros (MT) en Perú. La retención en el estudio fue ≥90%, con tres infecciones de VIH (3 Control) y 19 casos de GC/CT (10 Control, 9 CCP) a los seis meses. Hubo una disminución de las relaciones sexuales receptivas sin preservativos dentro del grupo Control (0.74, 95% CI: 0.60-0.91; p<0.01) y el grupo CCP (0.72, 0.55-0.94; p=0.02) a los seis meses. También hubo una disminución en el drinking expectancy a los seis meses dentro de los participantes quienes tomaban alcohol dentro del grupo CCP (0.89, 0.83-0.96; p<0.01), versus ningún cambio dentro del grupo Control (0.98, 0.92-1.04; p=0.54). La CCP fue eficaz en disminuir el drinking expectancy y el riesgo de contraer VIH dentro de HSH y MT en Perú.

Sexual Partnership-Level Correlates of Intimate Partner Violence Among Men Who Have Sex with Men and Transgender Women in Lima, Peru.

To improve understanding of factors associated with intimate partner violence (IPV) and explore its role in sexually transmitted infection (STI) acquisition, we analyzed partnership-level correlates of IPV among men who have sex with men (MSM) and transgender women (TW) in Peru. In a 2017 cross-sectional study of rectal STI screening and HIV prevention, MSM/TW completed a sociobehavioral survey addressing demographic characteristics, sexual risk behaviors, and substance use, and were tested for rectal gonorrhea and chlamydia, syphilis, and HIV. Generalized estimating equations estimated individual- and partner-level correlates of IPV. Of 576 participants (median age, 27 years), 7.9% (36/456) of MSM and 15.0% (18/120) of TW reported IPV with ≥ 1 of their last three partners. MSM/TW reporting IPV were more likely to meet criteria for an alcohol use disorder (74.1%) than participants reporting no IPV (56.7%; p < .01). Physical violence (4.5% MSM; 9.2% TW) was associated with stable partnerships (aPR 3.79, 95% CI 1.79-8.04), partner concurrency (4.42, 1.19-16.40), and participant alcohol (4.71, 1.82-12.17) or drug use (5.38, 2.22-13.02) prior to sex. Psychological violence (4.5% MSM; 5.0% TW) was associated with stable partnerships (2.84, 1.01-7.99). Sexual IPV was reported by 1.1% of MSM and 5.0% of TW. Physical, psychological, and sexual IPV were reported in sexual partnerships of Peruvian MSM and TW, particularly with stable partners and in conjunction with substance use.
