Page 3 Non-detectable viral load, stalled disease progression, reduced comorbidities Life expectancy approaches non-HIV+ for people optimally maintained on ART Sustained and significant population-level decreases in onward HIV transmission from ART scale up (TasP) Analogous benefits for people who use illicit drugs (PWUD) What about secondary clinical and non- clinical benefits of ART? Background Background: Clinical benefits of ART adherence Nosyk et al. (2013) Lancet ID; Montaner et al., (2014) Plos One

Page 4 Study objective: To examine whether becoming optimally adherent to ART is associated with improvements in a range of social, socio-economic and secondary clinical outcomes among people who use illicit drugs

Page 5 AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS) Design: Community-recruited cohort of people living with HIV/AIDS who use illicit drugs (ongoing since 1996) Data: Interviewer administered questionnaire and blood sample for serologic analysis at baseline and semi-annually Data linkages: Complete retrospective and prospective HIV clinical profile including all VL and ART dispensation from provincial treatment provider (BCCfE Drug Treatment Program) Methods: -Generalized linear mixed effects models for each outcome -Backwards model selection with adjustment for known/hypothesized confounders Data and Methods

Page 6 Outcome Measures Entering employment Ceasing involvement in prohibited income generation ≥95% adherence to ART Intimate relationship initiation Transitioning out of homelessness Addiction treatment enrollment Outcomes and Measures:

Page 7 Results: Sample and Baseline Characteristics Results (1)

Page 8 Results: Social/Socio-economic outcomes and adherence Results (2)

Page 9 Conclusions: Conclusions ART adherence increases the likelihood of reducing socio-economic vulnerability: -Ceasing prohibited income generation -Transitioning out of homelessness Improved socio-economic well-being can reinforce engagement in HIV care, quality of life and individual health outcomes Clinical and non-clinical importance of promoting early ART uptake for all in support of UNAIDS targets
