Measuring transactional sex in different contexts: How do tools to measure this practice perform in rural South Africa?

Abstract

Background: Adolescent girls and young women across sub-Saharan Africa are at disproportionate risk of HIV infection compared to their male counterparts. Transactional sex has been identified as an important proximate risk for infection in this population. Definitions and measures of transactional sex vary, necessitating improved measures to better estimate prevalence across settings, over time, and to understand the mechanisms through which transactional sex increases HIV risk. This article describes the results of cognitive interviews in rural KwaZulu-Natal in South Africa to evaluate the performance of an improved measure of transactional sex.
