Adolescent nutrition in West Africa is the focus of our latest Evidence Note. We have mapped research in this area to shed light on the trends in research and identify gaps in knowledge. Adolescents have often been overlooked in nutrition policy and programming. However, there is growing momentum to target this group through the Global Strategy for Women’s, Children’s and Adolescents’ Health (2016 – 2030), and the Adolescent Nutrition Call to Action: Better Data Now to Drive Better Programs and Policies in the Future. This note aims to inform the West Africa Health Organization and other decision-makers in West Africa to support policy and program development for adolescents in the region. The evidence note is available in both English and French.
