Literature review on linkages between child nutrition and economic growth
Beliyou Haile, Carlo Azzarri, Hee Eun Ahn ·
Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This literature review examines how child nutrition affects economic growth and identifies the causes of child malnutrition in developing countries. It shows that stunting and malnutrition remain widespread, with uneven progress across regions, and that good nutrition in early childhood has long-term effects on learning, productivity, and earnings. The review identifies three levels of causes: immediate factors like diet and disease, underlying factors like food security and healthcare access, and basic factors like economic resources and social conditions. It concludes that addressing child malnutrition requires coordinated action across multiple sectors including health, food systems, and social services.
Key points
- Stunting declined globally but increased in Africa due to slower progress and population growth
- Stunting in the first 1,000 days impairs cognitive development, educational performance, productivity, and increases healthcare costs
- Child undernutrition has three levels of causes: immediate (diet, disease), underlying (food security, care, healthcare), and basic (resources, economics, culture)
- Nutrition-specific interventions target immediate causes while nutrition-sensitive interventions target underlying causes
- Urbanization's effect on child nutrition depends on whether urban areas offer economic opportunities and health services
Limitations
This is a literature review that synthesizes existing research rather than presenting new data or evaluation results. It does not assess the effectiveness of specific interventions or provide evidence of what works best to improve child nutrition.
Abstract
This document summarizes published and grey literature on conceptual framework on the link between child nutrition and economic growth, determinants of child undernutrition, types of investments to enhance maternal and child nutrition, and linkages between urbanization and child nutrition. Several in-sights emerge from the review. First, and despite progresses over the last several decades, maternal and child malnutrition is still prevalent in developing countries and the progress has been uneven. While the percentage of chronically malnourished (stunted) children declined across the developing world, the number of stunted children in Africa increased due to slower reduction in stunting prevalence and population growth. Many developing countries are experiencing the coexistence of different forms of malnutrition including undernutrition, micronutrient deficiency, and overnutrition. Second, child undernutrition, especially stunting during the first 1,000 days of life, has several short- and long-term effects on individuals and economies that include impaired cognitive and non-cognitive development, poor educational performance, low productivity and earnings, and higher healthcare costs. Third, the determinants of child undernutrition are broadly classified as the immediate determinants including dietary intake and diseases; the underlying determinants that include household food security, quality of care and household living environment, and access to healthcare; and the basic determinants that include access to productive resources, stock of capital, as well as socioeconomic, political and cultural factors. Investments to enhance child nutrition can target either the immediate determinants (known as nutrition-specific investments) or the underlying determinants (known as nutrition-sensitive investments). Fourth, the effect of urbanization on child nutrition is mostly determined by the extent to which urban settlements offer their residents with better economic opportunities (e.g., better paying jobs and markets for nutritious food) and services (e.g., healthier living environments). Fifth, given the multilayer causes of child undernutrition, a multi-sectoral approach is needed to address the various determinants of undernutrition to improve maternal nutrition, promote optimal infant and young child feeding practices, enhance household food security, as well as improve healthy living environment and access to quality health care.
