Interpreting sexual behaviour data: validity issues in the multicentre study on factors determining the differential spread of HIV in four African cities

Abstract

In all four cities, we found evidence that men as well as women misreported their sexual behaviour, but overall it seems that under-reporting of sexual activity was not more common or more serious in the two high HIV prevalence cities than in the two low HIV prevalence cities. We believe that the main conclusions of the multicentre study still hold.
