Multiple sex partners


Multiple sex partners (MSP) is the measure and incidence of engaging in sexual activities with two or more people within a specific time period. Sexual activity with MSP can happen simultaneously or serially. MSP includes sexual activity between people with the same gender. MSP can also mean that one person may have a long-term relationship or relationships, and when the second relationship begins, the person can be said to have multiple sex partners. Another term, polyamoruous is a behavior and not a measure describing multiple romantically sexually or romantically committed relationships at the same time.

Young people having MSP in the last year is an indicator used by the Centers for Disease Control and Prevention (CDC) to evaluate risky behavior in adolescents and monitoring changes in the worldwide HIV/AIDS infection rates and deaths.

Epidemiologists and clinicians who quantify risks associated with MSP do so to identify those who have had sexual intercourse with more than one partner in the past 12 months. For the purposes of the World Health Organization (WHO)'s effort to eliminate HIV infection, quantifying measures progress in reducing the percentage of those with AIDS. The World Health Organization (WHO) has described their rationale by assuming that the spread of HIV in most locales depends upon the number of MSP. Those who have MSP possess a higher risk of HIV transmission than individuals that do not have multiple sex partners.

WHO uses indicators, such as MSP, age, mortality, morbidity, geographical location and signs and symptoms of disease. This is done so that change can be measured and so that the effect of indicators can be assessed.

Following the initial quantification of the number of MSP, the respondent is again surveyed three and then five years later. In addition to the survey, respondents' sexual histories are obtained. Analysis assists those conducting the study to verify and help define the term MSP.

For the indicator MSP, WHO has defined a summary of what it measures, rationale for the indicator, numerator, denominator and calculation, recommended measurement tools, measurement, frequency, and the strengths and weaknesses of the indicator.
