Supplementary feeding for improving the health of disadvantaged infants and children: what works and why?
3ie Systematic Review Summary 5, 2016
This report – a summary of a systematic review and a realist review – by Kristjansson et al. examines the evidence on whether supplementary feeding can improve the health of infants and children between three months and five years of age. The systematic review showed that supplementary food was more effective for children below two years and for those who were poorer or less well-nourished. The realist review found that prerequisites for programme success included the quality and quantity of the supplement and a reliable supply chain.
