As mortality rates decrease in British Columbia, Canada, supportive services (e.g. housing, food, counseling, addiction treatment) are increasingly conceptualized as critical components of care for people living with HIV/AIDS. Our study investigates social and clinical correlates of supportive service use across differing levels of engagement. Among 915 participants from the Longitudinal Investigations into Supportive and Ancillary health services (LISA) cohort, 742 (81%) reported using supportive services. Participants were nearly twice as likely to engage daily in supportive services if they self-identified as straight (95% confidence interval [CI], adjusted odds ratio [AOR]: 1.69), had not completed high school (95% CI, AOR: 1.97), had an annual income of < $15,000 (95% CI, AOR: 1.81), were unstably housed (95% CI, AOR: 1.89), were currently using illicit drugs (95% CI, AOR: 1.60), or reported poor social capital in terms of perceived neighborhood problems (95% CI, AOR: 1.15) or standard of living (95% CI, AOR: 1.70). Of interest, after adjusting for sociodemographic and socioeconomic variables, no clinical markers remained an independent predictor of use of supportive services. High service use by those demonstrating social and clinical vulnerabilities reaffirms the need for continued expansion of supportive services to facilitate a more equitable distribution of health among persons living with HIV.
