Global Child Nutrition Shift: Obesity Now Outnumbers Underweight Among Kids
For the first time in recorded history, more children worldwide are obese than underweight, according to a new report by UNICEF. As of 2025, approximately 9.4 percent of school-age kids (ages 5-19) are living with obesity, compared to 9.2 percent who are underweight.
This significant shift in global child nutrition has been years in the making. According to experts, the lines between obesity and underweight have converged over time due to changes in diet, lifestyle, and socioeconomic factors.
"We've seen a steady increase in childhood obesity rates over the past two decades," said Dr. Maria Neira, Director of the Department of Environment, Climate Change and Health at the World Health Organization (WHO). "This is largely driven by an environment that promotes unhealthy eating habits and physical inactivity."
The report highlights the need for a comprehensive approach to addressing child malnutrition, which now encompasses not only underweight but also obesity. Public health experts define malnutrition as existing on three dimensions: insufficient food intake, excessive consumption of unhealthy foods, and hidden hunger (inadequate nutrient intake).
Dr. Neira emphasized that both obesity and underweight are forms of malnutrition that require attention from policymakers, healthcare professionals, and families.
"Parents and caregivers play a crucial role in shaping children's eating habits and physical activity levels," she said. "Encouraging healthy behaviors, such as regular exercise and balanced meals, can help mitigate the risks associated with both obesity and underweight."
The report also underscores the importance of addressing socioeconomic determinants of health, including poverty, education, and access to healthcare.
"Childhood nutrition is a complex issue that requires a multifaceted approach," said Dr. Neira. "We must work together to create environments that support healthy growth and development, from early childhood through adolescence."
As the global community grapples with this new reality, experts stress the need for continued research, policy changes, and individual actions to promote healthy lifestyles.
Background:
Childhood obesity has been a growing concern worldwide since the 1990s. In 2000, approximately 3 percent of school-age children were obese, compared to nearly 13 percent who were underweight. Over time, the rates have converged, with obesity surpassing underweight in 2025.
Additional Perspectives:
Dr. Neira noted that addressing childhood malnutrition requires a long-term commitment from governments, healthcare systems, and individuals.
"We must prioritize evidence-based policies and programs that promote healthy eating habits, physical activity, and social support," she said. "By working together, we can create a healthier future for children worldwide."
Current Status:
The UNICEF report highlights the need for continued monitoring and evaluation of child nutrition trends. As policymakers and healthcare professionals work to address this new reality, experts emphasize the importance of individual actions in promoting healthy lifestyles.
Next Developments:
Researchers are expected to continue studying the causes and consequences of childhood obesity and underweight. Policymakers will likely explore strategies to promote healthy behaviors and reduce socioeconomic disparities in child nutrition.
As the global community navigates this shift in child nutrition, one thing is clear: a comprehensive approach that addresses both obesity and underweight is essential for promoting healthy growth and development among children worldwide.
