Abstract
Objectives: We elucidate the methodological challenges and approaches to overcome them in conducting a complex Campbell systematic review on feeding programmes to improve physical and psychosocial health in children 6 months to 5 years. Background: Under-nutrition contributes to five million deaths of children under five each year and one out of four children being underweight in developing countries. The crisis of child hunger and under-nutrition is not limited to developing countries. The mechanism associated with this global challenge interlaces both the biological and social sphere and requires complex interventions. Results: We identified three methodological challenges in the context of this review: 1) Mapping the review, 2) reporting effectiveness versus efficacy, and 3) Types of interventions: programmes versus controlled trials. 1. Mapping the review. We constructed a visual logic model to identify the components of this intervention, as well as contextual and population characteristics and how they are interrelated. This logic model was useful in defining the expected mechanisms of action, the focus of the review, and the methods for assessing the role of programme implementation and process issues, socioeconomic factors, intermediate and clinical outcomes, as well as adverse effects. 2. Reporting on Effectiveness versus Efficacy. Based on a previous review, we decided to explore the process of implementation and other effect modifiers using a ‘realist’ approach, drawing on both qualitative and quantitative studies. 3. Types of interventions; Controlled Trials versus Programmes. We included studies with appropriate control groups that met our inclusion criteria. We identified two main types of evaluation: those conducted as controlled trials of interventions, and those that were program evaluations conducted alongside the roll-out or implementation of school feeding programs. There are methodological differences in designing these two types of evaluations that need to be considered in the analysis and interpretation of results. Conclusions: We have identified methodological challenges and strategies to deal with them in the context of a complex systematic review of an international development intervention....
