Hypothesis
How accurately do individuals report their sexual behavior in a rural population in Malawi?
Conclusion
The study found significant under-reporting of non-marital partnerships, especially among women, which was influenced by age.
Supporting Evidence
- Under-reporting of sexual activity was identified through probing questions and HSV-2 antibody tests.
- Men reported about 4 times as many non-marital partnerships as women.
- The discrepancy in reporting was most marked for married women.
- Younger women showed a greater reluctance to report non-marital partnerships.
- The study used a whole population approach to triangulate data from different sources.
Takeaway
In Malawi, many people, especially women, don't always tell the truth about their sexual partners, and younger women are even less likely to report accurately.
Methodology
The study involved interviews with consenting individuals aged 15-59 about their sexual behavior, using probing questions and biological markers to assess validity.
Potential Biases
There is a risk of under-reporting due to social stigma associated with sexual behavior, particularly among women.
Limitations
The study may not include high-risk individuals like commercial sex workers, and the reliance on self-reported data can lead to under-reporting.
Participant Demographics
Participants were aged 15-59, with a response rate of 83% for women and 72% for men.
