Clinical HIV outcome trajectories associated with a history of child protective service out-of-home care: Longitudinal cohort findings with women living with HIV in Canada.

ABSTRACT

OBJECTIVES: Knowledge gaps exist regarding the effects of experiencing child protective services (CPS) out-of-home care (e.g. foster homes) among women with HIV. We examined whether CPS out-of-home care was associated with HIV clinical outcome trajectories among women with HIV in a longitudinal cohort study in Ontario, British Columbia, and Quebec, Canada. METHODS: At three timepoints across 5 years (2013-2018), we examined self-reported current antiretroviral therapy (ART) use and viral load (VL) detectability (>50 copies/mL). We used latent class growth analysis (LCGA) to identify trajectories of ART use and VL outcomes across study waves. LCGA identifies subgroups (classes) with similar trajectories within the sample. We assessed whether HIV outcome trajectories could be predicted by CPS history. We then conducted a mediation analysis to test whether a mental health latent construct mediated the association between CPS history and detectable VL. RESULTS: Nearly one-fifth (n = 272; 19%) of participants (n = 1422; mean age 42.8 years) reported CPS out-of-home care. Most participants (89%) were in classes that consistently used ART and had an undetectable VL. Individuals with CPS out-of-home care histories were twice as likely to have a consistently detectable VL (ß = 0.72, p = 0.02); there were no differences in ART use trajectories. In mediation analyses, we found an indirect path from CPS history to a consistently detectable VL via baseline mental health status (ß = 0.02, 95% confidence interval 0.005-0.04, p = 0.02), with a significant odds ratio (1.12, z = 2.43, p = 0.02). CONCLUSION: Among women with HIV in Canada, experiencing childhood CPS out-of-home care was associated with a reduced likelihood of achieving viral suppression, via poorer mental health.
