Microbicides Feasibility Study: Tanzania
The Department for International Development (DfID) funded a major multi-site Microbicides Development Programme. As part of the DfID Research Programme Consortium for Research and Capacity Building in Sexual and Reproductive Health and HIV in Developing Countries [LINK], the SPHSU supported a feasibility study for a trial of microbicides in Mwanza, Tanzania. This study was led by the London School of Hygiene and Tropical Medicine, in collaboration with the National Institute for Medical Research, Tanzania.
The study's aims were to:
characterise the sexual behaviour of vulnerable women
determine the acceptability of vaginal gel
identify obstacles and facilitating factors to women's involvement.
Caroline Allen (now Caribbean Health Research Council) and Nicola Desmond investigated the reliability and validity of coital diaries (CDs), and the level of support that women need from researchers to provide reliable and valid data (N=150). More sexual behaviour, and more socially unacceptable behaviours, were reported in CDs than in questionnaires, regardless of level of support. Higher levels of support from researchers resulted in more consistent reports between CDs and exit interviews. Exploration of service uptake revealed that issues of blood taking and identity influenced continued involvement in the study. The gel is likely to be acceptable to women and their partners but is subject to locally influenced sexual practices such as lubrication.
