Housing, HIV outcomes, and related comorbidities in persons living with HIV in Washington, DC.

Housing instability can hinder the ability of people with HIV (PWH) to maintain engagement in care, adhere to antiretroviral (ART) regimens, and achieve viral suppression. This analysis examined the association between housing instability and HIV outcomes, as well as the association between housing status and substance use disorders, mental health disorders, and sexually transmitted infections. Multivariable logistic regressions were performed using data from the DC Cohort, a longitudinal cohort of PWH. Among 8622 PWH, unstably housed PWH were significantly more likely to be prescribed ART (aOR: 1.4; 95%CI: 1.1, 1.8) yet were significantly less likely to be virally suppressed (aOR: 0.6; 95%CI: 0.5, 0.8). Unstably housed PWH were also significantly more likely to have a substance use or mental health disorder, which may inhibit PWH's ability to achieve viral suppression. Efforts to end the HIV epidemic should address housing to ensure treatment is optimized for key populations.
