The Preventing Malnutrition in Children under 2 Approach (PM2A) is a preventive approach that has been shown to be more effective in reducing the prevalence of stunting, being underweight, and wasting than a traditional recuperative program model. The Food and Nutrition Technical Assistance II Project (FANTA-2) commissioned a study to evaluate the impact of this preventive approach by conducting impact evaluations of two PM2A programs in Guatemala and Burundi.
