Global Obesity Rates Surpass Underweight for First Time Among School-Age Kids

Global Child Nutrition Shift: Obesity Outpaces Underweight for First Time For the first time in recorded history, more children worldwide are obese than underweight, according to a new report from 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. The shift is attributed to the convergence and eventual reversal of two previously distinct trends: the decline in underweight children and the rise in obese children. Twenty-five years ago, nearly 13 percent of kids were underweight, while just 3 percent had obesity. The lines have been closing ever since, with experts warning that both conditions are forms of malnutrition. "This is a wake-up call for parents, policymakers, and healthcare professionals," said Dr. Maria Neira, Director of the Department of Environment, Climate Change and Health at WHO. "We need to address the root causes of this shift, which include changes in diet, physical activity levels, and socioeconomic factors." The report highlights that both obesity and underweight are linked to poor nutrition, with children who consume high amounts of processed foods and sugary drinks being more likely to develop obesity. Conversely, those who lack access to nutritious food or experience food insecurity are at risk of being underweight. Experts emphasize the importance of a balanced diet and regular physical activity in preventing both conditions. "Children need a variety of whole foods, including fruits, vegetables, whole grains, lean proteins, and healthy fats," said Dr. Laura Schmidt, a pediatrician and nutrition expert. "Parents should also limit screen time and encourage outdoor play to promote physical activity." The shift in child nutrition trends has significant implications for global health. Obesity is linked to an increased risk of chronic diseases, such as diabetes, heart disease, and certain cancers. Underweight children, on the other hand, are more susceptible to infections and impaired growth. UNICEF's report calls for a comprehensive approach to address the root causes of this shift, including policy changes, education campaigns, and community-based initiatives. "We need to work together to create environments that support healthy eating and physical activity," said Neira. "This requires a sustained effort from governments, civil society, and individuals." As the world grapples with this new reality, experts stress the importance of consulting healthcare professionals for personalized advice on nutrition and lifestyle choices. By working together, we can prevent both obesity and underweight in children and promote healthy growth and development.
