By age

Data source: Ontario HIV Laboratory Cohort
 

Key points

  • In 2015, the majority of people with diagnosed HIV living in Ontario were 45 years of age or older (62.6%).
  • Cascade estimates were generally lower for younger individuals. In 2015, the percent of people with diagnosed HIV who were virally suppressed was 64.2%, 67.9%, 76.4%, 82.2%, 85.6% and 86.7% for those aged 24 or younger, 25 to 34, 35 to 44, 45 to 54, 55 to 64, and 65 or greater, respectively.
  • Higher cascade indicator estimates among older individuals may be due to several factors. For example, many older individuals have been diagnosed for a longer period of time and have had more opportunity to progress through the cascade. However, individuals who were newly diagnosed at older ages were also more likely to achieve viral suppression within six months of diagnosis. This suggests that the higher estimates among older people are not solely due to being diagnosed for a longer period of time (as newly diagnosed analyses adjust for time since diagnosis).
  • Data for the year 2015 only are shown below. Trends over time are available elsewhere on this website.

Definitions

Cascade indicator Definition (main)
Diagnosed Nominal HIV-positive diagnostic testor HIV viral load test, and not administratively lost to follow-up after 2 years
In care At least one VL test in a given year
On antiretroviral treatment Documented on ART, or ART status missing and suppressed, on last VL test in a given year
Virally suppressed VL less than 200 copies/mL on last VL test in a given year

 
 
Notes: Data provided by Public Health Ontario Laboratories. ART status documented on viral load test requisition by ordering provider and missing for 17-20% of requisitions. Individuals missing information on age were excluded (approximately 0.2%). Tables and Figures display main estimates only. A range of plausible values, based on alternative definitions, are available upon request. VL=viral load. ART=antiretroviral treatment.
