Hypothesis
The study evaluates the suitability of populations of sexually active women in two South African districts for a Phase III vaginal microbicide trial.
Conclusion
These populations might be suitable for Phase III microbicide trials provided that HIV incidence rates over time remain sufficiently high to support endpoint-driven trials.
Supporting Evidence
- HIV prevalence was 24% in Madibeng and 22% in Mbekweni.
- HIV incidence rates were 6.0/100 person-years in Madibeng and 4.5/100 person-years in Mbekweni.
- 99% of participants expressed willingness to participate in a microbicide trial.
Takeaway
The study looked at young women in South Africa to see how many had HIV and if they would join a trial for a new HIV prevention method. Most women were willing to participate.
Methodology
Cross-sectional studies followed by prospective cohort studies were conducted to estimate HIV prevalence and incidence.
Potential Biases
Potential underreporting of anal sex due to social desirability bias.
Limitations
The study's eligibility criteria limit the generalizability of the results, and the number of seroconversions was low, leading to wide confidence intervals.
Participant Demographics
Most participants were black African women aged 18-35, with a median age of 24 years.
