When researchers looked beyond single nutrition problems like stunting or obesity alone, they discovered a troubling reality: most low- and middle-income countries are falling further behind on global child nutrition targets. A comprehensive analysis of data from 48 low- and middle-income countries (LMICs) found that while 22 nations are projected to meet 2030 goals when looking at individual malnutrition types, the picture darkens significantly when children suffering from multiple forms of malnutrition simultaneously are included in the calculations .

The research, which analyzed nationally representative data from the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS), reveals a hidden crisis in child nutrition that global health organizations have largely overlooked. Malnutrition remains one of the most pressing public health concerns, contributing to roughly half of all deaths among children under five years of age worldwide .

What Is Coexisting Malnutrition, and Why Does It Matter?

Malnutrition isn't always a single problem. Children can experience stunting (being too short for their age), wasting (being too thin for their height), and obesity all at once, or in combinations. This phenomenon, called coexisting forms of malnutrition (CFM), has never been systematically tracked by international health bodies until now .

The distinction matters enormously. When researchers projected which countries would meet the World Health Organization's global nutrition targets by 2030, the results shifted dramatically when CFM was factored in. Currently, only 10 countries are on track to meet stunting, wasting, and obesity targets. By 2030, that number is projected to rise to 22 countries, but only if CFM is ignored. The moment you include children with overlapping malnutrition problems, the progress becomes far less impressive .

The global burden is staggering. According to the 2024 Joint Malnutrition Estimates report from UNICEF, WHO, and the World Bank, 23.2% of children under five experience stunting, 6.6% experience wasting, and 5.5% are overweight, meaning more than one-third of all young children globally face some form of malnutrition .

Which Countries Are Falling Behind, and Why?

The analysis identified stark regional disparities. Children living in Asia and Africa face the highest vulnerability to various forms of malnutrition, with more than half of children in these regions susceptible to different types of nutritional problems . Yemen and Zimbabwe are expected to remain significantly off-track toward 2030 targets, while stunting remains the most prevalent form of malnutrition, affecting 42 of the 48 countries studied. Nine nations are projected to have over 50% of their children affected by at least one form of malnutrition .

The root causes are interconnected and deeply rooted in poverty. Poverty, food insecurity, limited access to quality healthcare, and inadequate water and sanitation systems continue to perpetuate cycles of both undernutrition and emerging overnutrition in low- and middle-income countries . Approximately 59% of global stunting cases, 73% of global wasting cases, and 35% of global overweight cases among children under five reside in LMICs, according to the research .

What Factors Put Children at Highest Risk?

The study identified two dominant factors that determine whether a child will experience malnutrition. Maternal education and household wealth emerged as the strongest determinants of a child's nutritional status . Children whose mothers have no formal education and those from the poorest households face the highest risk of malnutrition in all its forms.

The inequalities are narrowing, but at a glacial pace. Disparities between wealthy and poor families are decreasing by only 1 to 2% per year, meaning it will take decades at the current rate to achieve equity in child nutrition .

How Can Countries Strengthen Their Response to Pediatric Malnutrition?

• Strengthen Nutrition Surveillance Systems: Governments and global health partners must establish robust systems that routinely capture data on coexisting forms of malnutrition, not just individual types. Current tracking mechanisms miss children with multiple overlapping nutritional problems.
• Implement Equity-Focused Policies: Programs must specifically target the poorest households and communities with limited maternal education, as these are the populations at highest risk. One-size-fits-all approaches will not close the gap.
• Invest in Maternal Education: Since maternal education is one of the two strongest determinants of child nutrition outcomes, expanding access to education for women and girls represents a critical long-term intervention.
• Address Underlying Structural Issues: Governments must tackle poverty, food insecurity, and inadequate access to clean water and sanitation, as these systemic problems perpetuate malnutrition cycles.
• Develop Prevention and Management Protocols: Health systems need standardized approaches to prevent and manage all forms of malnutrition at both national and individual levels, with special attention to children experiencing multiple nutritional problems simultaneously.

What Do the Projections Tell Us About Global Progress?

The research paints a sobering picture of global progress. The fact that many low- and middle-income countries are off-track to meet child-growth targets when coexisting malnutrition is considered suggests that current interventions are insufficient . The malnutrition crisis is not simply a problem of too little food or too much food; it is a complex issue involving poverty, education, healthcare access, and sanitation that requires multifaceted solutions.

The implications extend far beyond childhood. Pediatric malnutrition has profound consequences on children's health and development, with a synergistic relationship to childhood illness, disability, and cognitive impairment, which in turn are associated with negative economic outcomes throughout life . A child who experiences malnutrition in early years faces lifelong disadvantages in learning, earning potential, and health.

The 2030 global nutrition targets set by the WHO aim to reduce stunting to 40%, keep wasting below 5%, and halt the rise in pediatric obesity by 2030 . However, without addressing coexisting malnutrition and the underlying determinants of nutritional status, these targets will remain out of reach for many of the world's most vulnerable children. The research makes clear that business-as-usual approaches will not suffice; governments and global health partners must fundamentally rethink how they track, prevent, and manage malnutrition in all its forms.
