Mental health, substance use and HIV risk behaviors among HIV-positive adults who experienced homelessness in the United States - Medical Monitoring Project, 2009-2015.

Homelessness is a challenge to retention in HIV care and adherence to antiretroviral therapy. We describe the sociodemographic and behavioral characteristics of HIV-positive adults who reported recent homelessness. The Medical Monitoring Project is a complex sample survey of HIV-positive adults receiving medical care in the United States. We used weighted interview and medical record data collected from June 2009 to May 2015 to estimate the prevalence of depression, substance use, and HIV risk behaviors among adults experiencing recent homelessness. From 2009 to 2015, 8.3% of HIV-positive adults experienced recent homelessness. Homeless adults were more likely than housed adults to have major depression, to binge drink, use non-injection drugs, use injection drugs, and smoke. Over 60% of homeless adults were sexually active during the past year, with homeless adults reporting more condomless sex with an HIV-negative or unknown status sex partner than housed adults. Programs attempting to improve the health outcomes of HIV-positive homeless persons and reduce ongoing HIV transmission can focus on providing basic needs, such as housing, and ancillary services, such as mental health counseling or substance abuse treatment and counseling.
