The problem
Intervention: Food-assisted maternal and child health and nutrition programmes providing food rations of varying sizes, types (family vs individual rations, with different micronutrient supplements), and durations (full 1,000 days vs shorter periods)
Who it was tested with: Pregnant women and children aged 0-2 years in Burundi and Guatemala.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"Each was paired with a cluster‐randomized controlled trial to evaluate impact and compare the optimal quantity and composition of food rations (Guatemala, five treatment arms) and their optimal timing and duration (Burundi, three treatment arms)." The study design used randomized controlled trials with multiple treatment arms to rigorously compare different programme specifications and measure their cost-effectiveness for improving stunting.
Study focuses solely on stunting as outcome measure; does not examine other nutritional indicators, long-term child development, or broader health impacts. Findings specific to these two programme models and contexts.
