Cash transfer programmes in lower-income and middle-income countries: understanding pathways to nutritional change-a realist review protocol.

ABSTRACT:

Introduction

Child malnutrition continues to be a significant global public health concern. Nutrition-related interventions have changed and diversified over the last two decades, with increasing emphasis on nutrition-sensitive programmes that address underlying determinants of child malnutrition. Cash transfer programmes (CTPs) are used with increasing popularity in lower-income and middle-income countries to improve both food/nutrition insecurity and resilience. Available studies, however, provide mixed findings on the outcomes of CTPs for child nutritional status. This review is the first stage of a research project to develop evidence-informed theories of how CTPs affect child malnutrition. These will be empirically tested in the field and contribute to a better understanding of how, why, for whom and in what circumstances CTPs can be implemented to optimise impacts on child nutritional status.

Methods and analysis

This realist review is informed by available standards for realist reviews and follows a five-step process. In step 1, an initial scoping of literature identified potential contextual factors and underlying mechanisms that influence nutritional outcomes, and potential theories developed to address our research question. In step 2, a systematic literature search using multiple databases will be undertaken with papers screened using defined inclusion/exclusion criteria. In step 3, included studies will be appraised, data extracted into a bespoke data extraction tool and used to test and further refine our explanatory framework. The fourth step will synthesise, using a mix of inductive and deductive analytical processes to identify patterns, link chains of inference and tracking and linking of articles. The final step involves dissemination of a preliminary theory for feedback prior to empirically testing it in Kenya and Ethiopia where large-scale CTPs are being implemented.

Ethics and dissemination

This review will not involve primary data collection. Findings will be presented in accordance with Realist and Meta-Narrative Evidence Synthesis: Evolving Standards guidelines and published in a peer-reviewed journal.
