Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study examined the cost-effectiveness of food-assisted nutrition programmes for pregnant women and young children in Burundi and Guatemala. Researchers tested different combinations of food ration sizes, types and durations in each country, paired with randomized controlled trials. The findings show that effective nutrition programmes need sufficient ration size and duration to improve child stunting, and that longer programme periods can reduce per-beneficiary costs through spreading start-up expenses.
Key points
- In Guatemala, full-size family rations with individual corn-soy blend or micronutrient powder were most cost-effective for reducing stunting; smaller rations lowered costs but failed to reduce stunting
- In Burundi, providing food assistance for the full 1,000 days (pregnancy to age 2) achieved the lowest cost per percentage point reduction in stunting
- Reducing programme duration cut per-beneficiary costs but reduced effectiveness, showing programmes need sufficient dose to improve outcomes
- A 2-year programme extension could have saved 11% per beneficiary in Guatemala and 18% in Burundi by spreading start-up costs
- Nutrition programme costs do not scale linearly—simply cutting rations or duration does not proportionally reduce costs while maintaining effectiveness
Limitations
The study measures cost-effectiveness for stunting outcomes only and does not report on other nutritional indicators or longer-term child development impacts. The findings are specific to these two programme models in these countries and may not generalize to other contexts or intervention designs.
Abstract
Evidence on the cost‐effectiveness of multisectoral maternal and child health and nutrition programmes is scarce. We conducted a prospective costing study of two food‐assisted maternal and child health and nutrition programmes targeted to pregnant women and children during the first 1,000 days (pregnancy to 2 years). 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). We calculated the total and per beneficiary cost, conducted cost consequence analyses, and estimated the cost savings from extending the programme for 2 years. In Guatemala, the programme model with the lowest cost per percentage point reduction in stunting provided the full‐size family ration with an individual ration of corn–soy blend or micronutrient powder. Reducing family ration size lowered costs but failed to reduce stunting. In Burundi, providing food assistance for the full 1,000 days led to the lowest cost per percentage point reduction in stunting. Reducing the duration of ration eligibility reduced per beneficiary costs but was less effective. A 2‐year extension could have saved 11% per beneficiary in Guatemala and 18% in Burundi. We found that investments in multisectoral nutrition programmes do not scale linearly. Programmes providing smaller rations or rations for shorter durations, although less expensive per beneficiary, may not provide the necessary dose to improve (biological) outcomes. Lastly, delivering effective programmes for longer periods can generate cost savings by dispersing start‐up costs and lengthening peak operating capacity.
Findings the Hub has extracted
Each claim below is labelled by its type of design and links back to this report.
- 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)
- Population
- Pregnant women and children aged 0-2 years in Burundi and Guatemala
Key finding
In Guatemala, full-size family ration plus individual corn-soy blend or micronutrient powder provided lowest cost per percentage point reduction in stunting; reduced family ration size lowered costs but failed to reduce stunting
