Transactional sex and incident HIV infection in a cohort of young women from rural South Africa.

ABSTRACT:

Objective

In sub-Saharan Africa, young women who engage in transactional sex (the exchange of sex for money or gifts) with a male partner show an elevated risk of prevalent HIV infection. We analyse longitudinal data to estimate the association between transactional sex and HIV incidence.

Design

We used longitudinal data from a cohort of 2362 HIV-negative young women (aged 13-20 years) enrolled in a randomized controlled trial in rural, South Africa who were followed for up to four visits over 6 years.

Methods

The effect of transactional sex on incident HIV was analysed using stratified Cox proportional hazards models and cumulative incidence curves. Risk ratios were estimated using log-binomial models to compare the effects across visits.

Results

HIV incidence
