Women living with HIV are increasingly incarcerated and experience suboptimal HIV health outcomes post release from incarceration. Drawing on cohort data with cisgender and trans women living with HIV (Sexual Health and HIV/AIDS: Women's Longitudinal Needs Assessment), we used path analysis to investigate pathways from recent incarceration to optimal antiretroviral therapy (ART) adherence. We tested direct effects between recent incarceration, mediating variables, and ART adherence, along with indirect effects between incarceration and ART adherence through each mediator. We assessed model fit using chi-square, root-mean-square error of approximation (RMSEA), and comparative fit index (CFI). Our hypothesized model fit well to the data (χ2(1)=1.100; p=.2943; CFI = 1.000; RMSEA = 0.007). Recent experiences of homelessness, criminalized substance use, and gender-based violence each fully mediated the pathway between recent incarceration and optimal ART adherence. Findings highlight the need for safe and supportive housing, supports for criminalized substance use, and trauma and violence-informed care and practice post release from incarceration.
