Malnutrition contributes to 45% of all deaths in children under five worldwide, with diarrhea, pneumonia, malaria, and measles driving much of the toll. Severe acute malnutrition carries a 10 to 20% case fatality rate without treatment. The statistics below break down how stunting and wasting shape child survival across regions and risk groups.
Key Takeaways
- Malnutrition contributes to 45% of all deaths in children under five worldwide
- Iron deficiency affected 25% of preschool children globally, leading to anemia in 40 million under-fives
- In 2023, approximately 149 million children under age five worldwide suffered from stunting, a form of chronic malnutrition caused by insufficient nutrient intake over a prolonged period
- In 2022, 9 million children under five died before reaching their fifth birthday, many due to hunger-related causes
- In 2022, global under-five stunting prevalence stagnated at 22%, reversing prior declines
Child starvation remains widespread, and immediate action is crucial to prevent millions of avoidable deaths.
