Number of sexual partners among sexually active adolescents during a specified reference period Number of sexual partners among sexually active adolescents during a specified reference period Definition: The number of sexual partners during a specified reference period (e.g., the last 3, 6, or 12 months) among sexually active adolescents Data Requirement(s): Responses to survey questions on number of sexual partners during the specified reference period. Evaluators may want to disaggregate by the following age ranges: 10-14, 15-19, and 20-24. Data Source(s): Surveys of program participants or adolescents in the program‘s intended population Purpose: Having multiple sexual partners increases the risk of transmission of STIs and HIV/AIDS. This indicator provides a measure of how prevalent this high-risk behavior is in a program‘s intended population. However, because consistent condom use greatly reduces the risk of STI transmission, evaluators must consider the indicator in conjunction with the indicators pertaining to condom use (Percent of sexually active young people who used a condom at first/last sex, Percent of sexually active, unmarried adolescents who consistently use condoms) in order to assess the prevalence of high-risk behaviors. Issue(s): Because the indicator deals with a sensitive topic, there is reason to be concerned about the accuracy of reported information. Unfortunately, little methodological research has been undertaken to assess how accurately numbers of partners are reported in different settings.
