Assessing the existing evidence base on school food and nutrition policies: a scoping review

Overview

This report presents the outcomes of a scoping review conducted to identify and map existing evidence on the effects of school food and nutrition policies on health-related outcomes in children of school age as part of the initial preparation for undertaking the guideline development process by the WHO Nutrition Guidance Expert Advisory Group (NUGAG) Subgroup on Policy Actions.

In order to align with WHO’s Nutrition-friendly Schools Initiative (NFSI) framework, school-based food and nutrition interventions were assessed in terms of the impacts in four key policy areas, namely – the school community, the school curriculum, the school food and nutrition environment, and school nutrition and health services.
