A revised and updated version of the guidelines produced by three UK agencies sharing their programme experiences and tools. This is a practical resource to help those carrying out research or planning HIV/AIDS projects and programmes. Part one introduces the socio-economic and cultural context, and provides information on the relationship between gender and the spread of HIV/AIDS. The guidelines then provide frameworks to help identify and analyse the linkages between gender, HIV/AIDS and other factors, including the wider social, economic and political issues. They also provide participatory approaches to work on gender and HIV/AIDS with case studies that illustrate how these are being used in practice. The final section includes recent resources and websites with more information on the issues and approaches that are outlined in the guidelines.
