The number of obese children could rise to 228 million by 2040

The number of obese children is growing at a record pace and will reach 228 million by 2040, surpassing the number of underweight children for the first time, according to a new report, The World Obesity Atlas 2026. Most of the growth is in low- and middle-income countries, where most children live, the World Obesity Federation report said.

In 2025, 177 million children aged 5-19 were obese, representing 8.7 per cent of the world's children. By 2040, this is predicted to rise to 11.9 per cent of overweight children. Experts warn that without urgent action, this will lead to a serious strain on health systems and long-term health consequences for future generations.

Unhealthy maternal habits, physical inactivity, poor nutrition both at home and at school and inadequate breastfeeding are cited as reasons for the global rise in obesity.

The authors of the report note that childhood obesity increases the risk of chronic diseases at an early age, including heart disease, diabetes and liver disorders. Experts believe that by 2040, at least 120 million school-aged children may have early signs of weight-related diseases. In addition, obesity affects children's psychosocial development, reducing academic performance and quality of life.

The World Obesity Federation calls on governments for a comprehensive strategy: better nutrition, schooling, access to health care and equal opportunities for all children. WHO's global goals include reducing childhood overweight by 5 per cent by 2030 and increasing the proportion of children exclusively breastfed to 60 per cent.
