The impact of conditional cash transfer programmes on child nutrition: a review of evidence using a programme theory framework

The authors reviewed the evidence regarding the impact of conditional cash transfer (CCT) programmes on child nutrition outcomes, using a programme theory framework. They developed a programme impact model and synthesised evidence regarding the pathways through which CCTs may improve child nutrition. CCT programmes significantly improve child anthropometry but have very little impact on micronutrient status. The programmes also have a positive impact on several of the outcomes in the pathways to improved nutrition. The authors found an enormous gap in knowledge about the mechanisms by which CCT programmes improve nutrition. In order to reach their full potential, the programmes need to have a better defined set of nutrition actions grounded in programme theory.
