Bold reality: nearly one million young children die each year because of growth failure, a devastating consequence that prevents countless kids from reaching their fifth birthday. This troubling figure places CGF as the third leading risk factor for mortality and morbidity in children under five, according to the Global Burden of Disease 2023 study published in The Lancet Child & Adolescent Health.
While global deaths linked to child growth failure fell from about 2.75 million in 2000 to around 880,000 in 2023, the impact remains severe and highly concentrated in specific regions. Sub-Saharan Africa accounted for 618,000 CGF-related deaths, and South Asia for 165,000 in 2023.
Among CGF indicators, being underweight carries the largest disease burden, responsible for about 12% of all deaths in children under five. Wasting accounts for roughly 9%, and stunting for about 8%. Importantly, researchers found a higher number of children affected by stunting than previously estimated.
Growth failure raises the risk of death and disability from a range of diseases, with almost 800,000 under-five deaths attributed to lower respiratory infections, diarrheal diseases, malaria, and measles. In 2023, CGF was linked to 77% of diarrheal disease deaths and 65% of lower respiratory infection deaths in sub-Saharan Africa. South Asia showed similarly high proportions, with 79% and 53% for these two causes respectively. In the high-income regions—where CGF deaths are fewer—the share of deaths from these causes stood at about 33% and 35%.
Dr. Bobby Reiner, co-author and professor at the Institute for Health Metrics and Evaluation at the University of Washington School of Medicine, explains that the drivers of CGF are complex and cumulative. They include feeding problems, food insecurity, climate change, poor sanitation, and conflict. “Therefore, no single strategy will fix health outcomes across all regions.”
Key insights from the study emphasize that most stunted infants show growth failure signs within the first three months of life, highlighting the critical need for interventions before and during pregnancy. A destructive cycle links wasting and stunting: stunting raises the risk of future wasting, and wasting can worsen stunting. This cycle often intensifies as children grow older. Early-life growth failure may reflect being born too small or prematurely, while growth issues in later infancy and early childhood can point to ongoing nutritional deficits, repeated infections, or other underlying factors.
Dr. Reiner adds that, given the difficulty of reversing stunting, the latest estimates should guide targeting of high-prevalence areas. Early detection and timely intervention are essential to altering trajectories for affected children.
