This review was prepared for UNAIDS by Peter Aggleton, Elaine Chase, Kim Rivers and Paul Tyrer from the Thomas Coram Research Unit at the Institute of Education, University of London. All aspects of the publishing process were coordinated by Andrea Verwohlt, UNAIDS.

The authors would like to thank the organizations and individuals - too numerous to mention individually - who generously provided their time, information and advice during the preparation of this review. We owe a particular debt of appreciation to UNAIDS desk officers, intercountry teams and country programme officers for nominating the projects described in this report, and to the organizers and coordinators of these activities for their descriptions of work being undertaken. While efforts have been made to check the accuracy of all statements and descriptions, any remaining errors or inaccuracies are the responsibility of the authors.
