Informing infant and young child feeding programming in humanitarian emergencies: An evidence map of reviews including low and middle income countries.

Around 200 million people were affected by conflict and natural disasters in 2015. Whereas those populations are at a particular high risk of death, optimal breastfeeding and complementary feeding practices could prevent almost 20% of deaths amongst children less than 5 years old. Yet, coverage of interventions for improving infant and young child feeding (IYCF) practices in emergencies is low, partly due to lack of evidence. Considering the paucity of data generated in emergencies to inform programming, we conducted an evidence map from reviews that included low- and middle-income countries and looked at several interventions: (a) social and behavioural change interpersonal and mass communication for promoting breastfeeding and adequate complementary feeding; (b) provision of donated complementary food; (c) home-based fortification with multiple micronutrient powder; (d) capacity building; (e) cash transfers; (f) agricultural or fresh food supply interventions; and (g) psychological support to caretakers. We looked for availability of evidence of these interventions to improve IYCF practices and nutritional status of infants and young children. We identified 1,376 records and included 28 reviews meeting the inclusion criteria. The highest number of reviews identified was for behavioural change interpersonal communication for promoting breastfeeding, whereas no review was identified for psychological support to caretakers. We conclude that any further research should focus on the mechanisms and delivery models through which effectiveness of interventions can be achieved and on the influence of contextual factors. Efforts should be renewed to generate evidence of effectiveness of IYCF interventions during humanitarian emergencies despite the challenges.
