People Living With HIV in St. Petersburg, Russia: Gender and Exposure Group Differences in HIV Care Engagement, Psychosocial Health, Substance Use, and Transmission Risk Behavior.

This study examined psychosocial and health needs of persons living with HIV (PLWH) in Russia. The study combined baseline datasets from two social network samples of PLWH in St. Petersburg ( = 872). Samples were recruited between 2014 and 2018 by enrolling a PLWH seed who was either out-of-care or treatment nonadherent as well as network members surrounding each seed, assessing each participant's HIV care, transmission risk, substance use, and mental health characteristics. Almost one-quarter of participants said they were never offered antiretroviral therapy (ART), and-among those offered ART-one-quarter refused or discontinued therapy and 45% were <95% ART-adherent. Almost half of participants had detectable viral load, and many reported continued condomless intercourse with potentially nonconcordant serostatus partners or needle sharing. Over 46% of participants had elevated scores on measures of depression, hopelessness, state anxiety, or poor social support. Study findings illustrate unmet needs of PLWH in Russia.
