The project was implemented in urban areas of Saint- Louis and Louga, in northwestern Senegal, and was called Improving the Reproductive Health of Youth in Senegal. 1 The project supported a public sector, multisector intervention in communities, health facilities, and schools to enhance young people’s knowledge and behavior regarding reproductive health and HIV prevention, and systematically tested its feasibility, acceptability, effectiveness and costs.
