Optima Nutrition : An Allocative Efficiency Tool to Reduce Childhood Stunting by Better Targeting of Nutrition-Related Interventions
·
Summary
Written by AI, not yet AICS's view · claude-sonnet-5-5The report presents 'Optima Nutrition', a modelling tool that helps decide how to split a limited nutrition budget across interventions to reduce childhood stunting. It uses an adapted version of the Lives Saved Tool and covers six nutrition interventions. The authors demonstrate it on 7 districts in Bangladesh, using public data such as DHS and data from a costing study. They estimate that better targeting of existing funds could reduce stunting without any extra money.
Key points
- Six interventions are included: antenatal micronutrient supplementation, balanced energy-protein supplementation, exclusive breastfeeding promotion, promotion of improved infant and young child feeding (IYCF), public provision of complementary foods, and vitamin A supplementation.
- Nutrition funding in the Bangladesh example is limited, estimated at $0.75 per person in need per year.
- With no extra resources, better targeting could increase the cumulative number of children living without stunting by 1.3 million (an extra 5 percent) by 2030 compared with the current allocation.
- Priority interventions are promotion of improved IYCF practices and vitamin A supplementation. Public provision of complementary foods should come next once these are adequately funded.
- Programme efforts should focus most on the regions of Dhaka and Chittagong, which have the most stunted children.
Limitations
The results are model-based projections for a set of Bangladesh districts, not observed outcomes from a tested programme. The abstract does not describe model assumptions, uncertainty or validation, so we cannot judge how reliable the estimated gains are.
Abstract
Child stunting due to chronic malnutrition is a major problem in low- and middle-income countries due, in part, to inadequate nutrition-related practices and insufficient access to services. Limited budgets for nutritional interventions mean that available resources must be targeted in the most cost-effective manner to have the greatest impact. Quantitative tools can help guide budget allocation decisions. The Optima approach is an established framework to conduct resource allocation optimization analyses. The authors applied this approach to develop a new tool, ‘Optima Nutrition’, for conducting allocative efficiency analyses that address childhood stunting. At the core of the Optima approach is an epidemiological model for assessing the burden of disease; we use an adapted version of the Lives Saved Tool (LiST). Six nutritional interventions have been included in the first release of the tool: antenatal micronutrient supplementation, balanced energy-protein supplementation, exclusive breastfeeding promotion, promotion of improved infant and young child feeding (IYCF) practices, public provision of complementary foods, and vitamin A supplementation. To demonstrate the use of this tool, we applied it to evaluate the optimal allocation of resources in 7 districts in Bangladesh, using both publicly available data (such as through DHS) and data from a complementary costing study. Optima Nutrition can be used to estimate how to target resources to improve nutrition outcomes. Specifically, for the Bangladesh example, despite only limited nutrition-related funding available (an estimated dollar 0.75 per person in need per year), even without any extra resources, better targeting of investments in nutrition programming could increase the cumulative number of children living without stunting by 1.3 million (an extra 5 percent) by 2030 compared to the current resource allocation. To minimize stunting, priority interventions should include promotion of improved IYCF practices as well as vitamin A supplementation. Once these programs are adequately funded, the public provision of complementary foods should be funded as the next priority. Programmatic efforts should give greatest emphasis to the regions of Dhaka and Chittagong, which have the greatest number of stunted children. A resource optimization tool can provide important guidance for targeting nutrition investments to achieve greater impact. (World)
