Theme Health
Code PH-SXH-1.9
MDG code MDG-6.1
Sub-theme Sexual Health (HIV/AIDS & STI)
Name HIV prevalence among population aged 15-24 years (MDG 6.1)
Definition Impact indicator. Indication of sexual behaviour, sexual activity amongst young people. Indication of status of HIV epidemic amongst young people
Calculation/Formula (Number of existing active cases of HIV among youth population aged 15-24 years / Total population aged 15-24 years) x 100
Unit of Measure %
Range (eg Age) 15-24 years
Purpose/Rationale It measures progress towards reducing HIV infection. The goal in the response to HIV is to reduce HIV infection. HIV prevalence at any given age is the difference between the cumulative numbers of people that have become infected with HIV up to this age minus the number who have died, expressed as a percentage of the total number alive at this age. At older ages, changes in HIV prevalence are slow to reflect changes in the rate of new infections (HIV incidence) because the average duration of infection is long. Furthermore, declines in HIV prevalence can reflect saturation of infection among those individuals who are most vulnerable and rising mortality rather than behaviour change. At young ages, trends in HIV prevalence are a better indication of recent trends in HIV incidence and risk behaviour. Thus, reductions in HIV incidence associated with genuine behaviour change should first become detectable in trends in HIV prevalence figures for 15–24 years old (or even earlier in 15-19-year-olds if this age breakdown is available). Where available, parallel behavioural surveillance survey data should be used to aid interpretation of trends in HIV prevalence.
