Bold reality: nearly one million young children die each year because of growth failure, a crisis that remains a major driver of mortality and morbidity for children under five. This stark finding comes from the Global Burden of Disease 2023 study published in The Lancet Child & Adolescent Health, which shows that while deaths linked to child growth failure (CGF) declined from 2.75 million in 2000 to 880,000 in 2023, the resulting health burden is still profound and heavily concentrated in specific regions.
Regionally, CGF-related deaths cluster in sub-Saharan Africa, where 618,000 deaths were recorded, and in South Asia, with 165,000 deaths. Among CGF indicators, being underweight accounts for the largest share of the disease burden, driving 12% of all deaths in children under five, followed by wasting at 9% and stunting at 8%. Importantly, researchers found that stunting is more prevalent than previously estimated, indicating a broader scope of impact than earlier thought.
CGF raises the risk of mortality and disability from a range of diseases. Nearly 800,000 children under five died from causes such as lower respiratory infections, diarrheal diseases, malaria, and measles in connection with CGF. In 2023, 77% of diarrheal deaths and 65% of deaths from lower respiratory infections in sub-Saharan Africa were associated with CGF. South Asia showed similarly high proportions, with 79% and 53% for those two causes, respectively. The high-income regions, which have the lowest CGF-related mortality, still show substantial shares, at about 33% for diarrheal deaths and 35% for lower respiratory infections.
The researchers emphasize that the factors driving CGF are complex and cumulative—ranging from feeding practices and food insecurity to climate change, poor sanitation, and conflict. As Dr. Bobby Reiner notes, no single strategy suffices to improve health across all regions; targeted, multifaceted interventions are essential.
Key insight: most stunted infants exhibit growth failure within the first three months of life, highlighting the critical importance of interventions during pregnancy and early infancy. The cycle between wasting and stunting can reinforce itself—stunting increases the risk of future wasting, and wasting can worsen stunting—creating a compounding problem as children age. Early-life growth failure often reflects low birth weight or prematurity, while growth issues later in infancy and early childhood may signal ongoing nutritional gaps, repeated infections, or other contributing factors.
Dr. Reiner cautions that reversing stunting is difficult, so the latest estimates should guide where to focus prevention and early detection efforts. Prioritizing high-prevalence locations for screening and timely intervention can curb CGF’s lifelong health toll.
