Objectives: The objective of this paper was to review various nutritional interventions targeted at under-five children in countries that had suffered from natural disasters and to analyse their effect on nutrition-related outcomes.
Design: Systematic review.
Setting: Countries that had suffered from natural disasters.
Participants: Children aged <5 years who were given any nutritional intervention to improve overall nutritional status after a natural disaster.
Primary and secondary outcome measures: Primary nutrition-related outcomes were stunting, wasting and underweight. The secondary nutrition-related outcome was anaemia.
Results: Of the 1218 studies that the reviewers agreed on, five matched the inclusion criteria and were included in this narrative synthesis. Four studies were longitudinal and one was cross-sectional in design. Food supplementation was an integral part of nutritional interventions in all the included studies. The most consistent nutritional outcome in all five included studies was reduced prevalence of wasting, followed by reduced prevalence of underweight in four, stunting in three and anaemia in one of the five included studies. The largest reduction in the prevalence of wasting and underweight was reported by the study in Sri Lanka. Overall, the quality of evidence ranged from moderate to weak.
Conclusions: Integrated nutrition interventions using locally available health resources yielded the best results. However, sound evidence on the most effective interventions is still lacking. Intervention studies with comparison groups are necessary to obtain more robust evidence on the effectiveness of nutrition interventions.
