Access to antiretroviral therapy for adults and children with HIV infection in developing countries: Horizons studies, 2002–2008
The Access-to-Treatment research initiative of the Population Council's Horizons program undertook 11 projects across Asia and sub-Saharan Africa from 2002 to 2008. The projects included a variety of cross-sectional exploratory studies, situation analyses, and longitudinal randomized, controlled intervention studies that examined service delivery, community awareness, health-seeking behaviors, adherence, cost, and other factors affecting treatment for adults and children infected with human immunodeficiency virus (HIV). This article summarizes the key findings and lessons learned from these projects, and examines cross-cutting issues such as stigma, quality of life, and sexual-risk behaviors among people living with HIV and acquired immunodeficiency syndrome on antiretroviral therapy. The article concludes with recommendations for evidence-based programming and future research around treatment for both children and adults.
