In the general population four additional indicators are proposed:
1) Age at first intercourse and/or being sexually active (having had sexual intercourse in the last 12 months), as detailed in the table below.
Title & definition: Age at first intercourse* and/ or being sexually active in the last 12 months
|Purpose and rationale||To assess long term trends in age at first intercourse, to assess the proportion of young people having sex at a very young age|
Every 4-5 years in the general population and young people
|Strengths and weaknesses||Simple|
|Additional sources of information||* allows for construction of UNGASS indicator No 15: percentage of young women and men aged 15-24 who have had sexual intercourse before the age of 15. Also similar to HBSC indicator: percentage of sexually active in 15 year olds.|
2) Recent STI (in the last 12 months): this indicator of risk is seen as important; however, as no commonly agreed satisfactory indicator is currently available, more research is needed and no specific definition is proposed.
3) Concurrency (in the last 12 months): this indicator measuring the simultaneous existence of several partners over a given period is also seen as important. However, as yet, there is no commonly agreed indicator.
4) Types of drugs consumed (in the last 12 months): this indicator has been mentioned as relevant in several countries and populations. Several sets of questions related to drug consumption exist, many of them are context- or age- dependent (ESPAD survey (l) , WHO-HBSC survey (m) , EMCDDA treatment demand indicator TDI for IDU (n), etc.), and can be used for cross country comparison in defined populations; no indicator common to all populations is proposed.
