About 3ieThe International Initiative for Impact Evaluation (3ie) is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding and producing high-quality evidence of what works, how, why and at what cost. We believe that better and policy-relevant evidence will help make development more effective and improve people's lives. 3ie systematic reviews 3ie-supported systematic reviews examine available high-quality evidence on the effects of social and economic development interventions in low-and middle-income countries. They follow scientifically recognised review methods and are quality assured according to internationally accepted standards. 3ie publishes the full reviews online as they have been accepted from authors in partial fulfilment of their grants. 3ie also publishes summaries and/or briefs based on the full reviews that are designed for use by policymakers and programme managers. Funding for the systematic review and summary report was provided by 3ie's donors and members that provide institutional support. A complete listing is provided on the 3ie website.

ObjectivesSupplementary feeding programmes for children vary greatly, but the long-term goals generally include improved survival, improved growth and health, and normal cognitive and behavioural development. Some supplementary feeding programmes have the intermediate goal of curing (or at least ameliorating) existing undernutrition, while others aim to prev...
