Defining Malnutrition: Beyond a Single Metric
Determining "what country has the worst malnutrition" is not as straightforward as it may seem. There is no single international ranking, as the "worst" depends on the metrics used, such as prevalence (percentage of the population affected) versus total number of people affected. The duration of the crisis also matters, differentiating between severe acute malnutrition (SAM), often linked to recent emergencies, and chronic malnutrition, like stunting, which results from long-term deprivation. The answer therefore points not to a single nation but to a group of countries and regions where multiple and compounding factors have created extreme conditions.
The World's Most Affected Malnutrition Hotspots
While various nations face severe challenges, several consistently appear on watch lists for either high rates or catastrophic numbers of affected people, often due to ongoing conflict and political instability.
Somalia
Frequently cited for having one of the highest prevalence rates of malnutrition, Somalia has been in a prolonged state of crisis. The country has faced decades of civil war and extreme climate events, including droughts and flooding, that have decimated food production and disrupted supply chains. In 2021-2023, it was estimated that over 51% of the population suffered from some form of malnutrition.
Democratic Republic of Congo (DRC)
The DRC has one of the world's largest hunger crises in terms of the total number of people impacted, despite often being far from the headlines. Fueled by decades of conflict and poverty, over 25 million people cannot meet their basic food needs. Conflict-driven displacement and endemic poverty have exacerbated food insecurity across the country.
Yemen
Conflict has created a devastating humanitarian emergency in Yemen, leading to one of the world's most severe food crises. The ongoing civil war has pushed millions to the brink of starvation, with rising food prices and a collapsing economy limiting access to food and aid. Conflict is the primary driver of this immense and protracted crisis.
South Sudan and Haiti
These countries are also consistently identified as hotspots of extreme hunger due to a toxic mix of conflict, displacement, and economic and climate shocks. In South Sudan, large-scale displacement and repeated flooding continue to prevent households from farming. In Haiti, gang violence is worsening an already dire hunger crisis by disrupting supply chains and blocking aid.
The Vicious Cycle of Causes
Malnutrition is not an isolated issue but the result of a complex interplay of factors that reinforce one another. The primary causes found in the most affected nations are:
- Conflict and Political Instability: Widespread violence, civil war, and displacement disrupt food production, destroy infrastructure, and block humanitarian access, making food and aid delivery nearly impossible.
- Poverty and Economic Shocks: Low household income and high food prices directly impact a family's ability to afford nutritious food. Economic crises are a major driver of hunger in many regions.
- Climate Change and Natural Disasters: Extreme weather events like droughts and floods destroy crops and livelihoods, contributing to chronic undernutrition and acute food shortages.
- Poor Sanitation and Hygiene: Lack of access to clean water and sanitation can lead to diseases like diarrhea, which prevent the body from absorbing nutrients, worsening malnutrition.
- Maternal Malnutrition: The nutritional status of mothers, particularly during pregnancy, is a significant predictor of a child's nutritional outcome and long-term health.
Comparison of Malnutrition Burden in Select Countries
This table highlights the varying nature of malnutrition crises by comparing different metrics in several severely affected regions.
| Country/Region | Primary Driver | Pre-Pandemic Malnutrition Prevalence (%) | Total People Facing Acute Hunger (2024/2025 Est.) | Notes |
|---|---|---|---|---|
| Somalia | Conflict, Drought | ~51% (2021-23 estimate) | >6 million | Known for one of the highest percentage rates globally. |
| Yemen | Civil War | 39.5% | ~17 million | Protracted civil war created one of the worst food crises. |
| Democratic Republic of Congo | Conflict, Poverty | Not specified | ~26.4 million | World's largest number of food-insecure people. |
| Tigray, Ethiopia (Region) | Armed Conflict | <10% (Pre-Conflict) | Not specified | Extreme spike in acute malnutrition rates due to recent conflict and siege. |
| Afghanistan | Conflict, Economic Collapse | 40% stunted (Children under 5) | ~12.4 million | Decades of conflict exacerbated by economic collapse and aid cuts. |
Long-Term Effects of Severe Malnutrition
Severe malnutrition, especially during the critical first 1,000 days of life, has devastating and often irreversible long-term consequences.
- Stunted Growth: Chronic undernutrition leads to stunting, which results in lower height for age and impairs physical development.
- Cognitive and Behavioral Impairment: Malnutrition can permanently affect brain development, leading to lower cognitive function, poor academic performance, and lower self-esteem in adulthood.
- Weakened Immune System: Malnourished individuals have a compromised immune system, making them more susceptible to infectious diseases.
- Increased Chronic Disease Risk: Studies show a link between childhood stunting and a higher risk of chronic diseases like obesity and cardiovascular issues in adulthood.
- Reduced Economic Productivity: Impaired physical and cognitive development reduces economic potential, trapping individuals and communities in a cycle of poverty and poor health.
Global Efforts and Required Action
Ending malnutrition requires a multi-sectoral approach that addresses its root causes. The World Food Programme (WFP), a Nobel Peace Prize laureate, plays a critical role in providing emergency food relief and building long-term resilience. Other measures include investing in climate-smart agriculture, social safety nets, and improving WASH infrastructure in at-risk areas. Collaboration between governments, international organizations, and local communities is essential for creating sustainable solutions.

Conclusion
While singling out one country with the worst malnutrition is a difficult and nuanced task, data points to regions in conflict and areas hit hardest by poverty and climate change as those most in need. Countries like Somalia, Yemen, and the DRC face some of the most critical situations, defined by either staggering prevalence rates or immense numbers of affected people. The crisis is complex, driven by interconnected factors, and requires sustained, collaborative global action to break the cycle of hunger and poverty.
