In 2011, WHO and other international organizations launched the Nutrition-Friendly Schools Initiative, which provides a framework for implementing integrated intervention programmes to improve the health and nutritional status of school-age children and adolescents and uses the school as the programme setting (including nurseries and kindergartens). This initiative brings together parents, the local community and health services to promote children's health and nutritional wellbeing (WHO, 2011b).
