New Optimism in the HIV Sector
Ontario s HIV Strategy to 2026 Goals: 1. Improve the health and well-being of populations most affected by HIV 2. Promote sexual health and prevent new HIV, STI and hepatitis C infections 3. Diagnose HIV infections early and engage people in timely care 4. Improve health, longevity and quality of life for people living with HIV 5. Ensure the quality, consistency and effectiveness of all provincially funded HIV programs and services

Ontario s Prevention, Engagement and Care Cascade
How close is Ontario to Meeting the Targets?
Change in the Care Cascade, 2000-2015 Cascade Summary, Ontario, 2000-2015 100% 90% Percent of diagnosed people living with HIV 80% 70% 60% 50% 40% 30% 20% 10% 0% 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 In care On treatment Suppressed Data provided by the Public Health Ontario Laboratory. In Care = 1 VL test. On Treatment = Documented on treatment on last VL or treatment documentation missing but supressed on last VL. Supressed = VL< 200 copies/ml on last VL test

Key Syndemic Drivers of HIV in Ontario: Depression, alcohol and drug use, smoking OHTN Cohort Study data there are significant health and social factors that need attention: 28% experience depression 50 Syndemic risk factors count 37% have hazardous alcohol use 40% smoke tobacco (compared to 14% of general population) 20% use recreational drugs (excluding marijuana) % 40 30 20 10 31 32 23 14 0 0 1 2 3
Syndemic Drivers of HIV in Ontario Other OHTN Cohort Study Syndemic Drivers: 57% live on <$20,000/year 25% experienced history of trauma (sexual abuse as a child by someone close to them) 38% experienced intimate partner violence (of those, 50% were sexually abused and 89% were emotionally abused)
Syndemic Drivers of HIV in Ontario CIHR Funded Positive Spaces Healthy Places: 50% Housing instability Overall, those who were unstably housed had: more substance use, higher levels of stress, higher rates of depression, and lower CD4 counts and viral loads Indigenous participants in our study were more likely to live in unstable housing, have a history of homelessness, experience housing discrimination and have a history of incarceration
Impact of Syndemics on Risk and Health Outcomes Brennan et al (2012) Higher syndemic index Mustanski et al (2007) increased sexual risk behaviour, self-reported HIV infection, and social marginalization Increasing # of psychosocial health problems higher rate of unprotected anal intercourse and HIV infection among young MSM Friedman et al (2015) Higher syndemic count higher viral load and lower ART adherence in HIV+ MSM Rourke et al (2016) Higher # of syndemic factors declining levels of HIV care engagement and poorer HIV treatment outcomes

Health Opportunities for Ontarians Living with HIV Despite these health/social challenges, many people living with and at risk of HIV demonstrate remarkable resilience How can we build on those strengths to stop the syndemics that drive HIV?
