Name Proportion of population 15-24 with knowledge of HIV/AIDS (MDG 6.3)
Definition Proportion of respondents who correctly answer 5 standard questions on HIV transmission and prevention, as a percentage of all respondents in a population survey. [UN definition = Percentage of young persons aged 15–24 years who correctly identify the two major ways of preventing the sexual transmission of HIV (using condoms and limiting sex to one faithful, uninfected partner), who reject the two most common local misconceptions about HIV transmission and who know that a healthy-looking person can transmit HIV].
Calculation/Formula Number of respondents aged 15-24 who gave the correct answer to all five questions / Number of all respondents aged 15-24 years x 100
Unit of Measure %
Range (eg Age) 15-24 years
Assumptions This indicator is constructed from responses to the following set of prompted questions: 1. Can the risk of HIV transmission be reduced by having sex with only one uninfected partner who has no other partners? 2. Can a person reduce the risk of getting HIV by using a condom every time they have sex? 3. Can a healthy-looking person have HIV? 4. Can a person get HIV from mosquito bites? 5. Can a person get HIV by sharing food with someone who is infected?
Limitations Surveying most-at-risk populations can be challenging. Consequently, data obtained may not be based on a representative sample of the national, most-at-risk population being surveyed.
Purpose/Rationale Knowledge of HIV transmission and prevention is a prerequisite for adoption of behaviours that reduce HIV risk. It measures progress towards universal knowledge of the essential facts about HIV transmission. HIV epidemics are perpetuated primarily via sexual transmission of infection to successive generations of young people. Sound knowledge about HIV is an essential pre-requisite—albeit, often an insufficient condition—for adoption of behaviours that reduce the risk of HIV transmission.
