Obesity surpassed underweight as the more prevalent form of malnutrition this year, affecting 1 in 10 – or 188 million – school-aged children and adolescents, and placing them at risk of life-threatening disease, UNICEF warned in a new report today. 

Feeding Profit: How Food Environments are Failing Children draws on data from over 190 countries and finds the prevalence of underweight among children aged 5-19 has declined since 2000, from nearly 13 per cent to 9.2 per cent, while obesity rates have increased from 3 per cent to 9.4 per cent. Obesity now exceeds underweight in all regions of the world, except sub-Saharan Africa and South Asia.

According to the findings, several Pacific Island countries have the highest prevalence of obesity globally, including 38 per cent of 5 to 19-year-olds in Niue, 37 per cent in Cook Islands, and 33 per cent in Nauru. These levels – which have all doubled since 2000 – are largely driven by a shift from traditional diets to cheap, energy-dense, imported foods.

Meanwhile, many high-income countries continue to have high levels of obesity, for example 27 per cent of 5 to 19-year-olds in Chile are living with obesity, 21 per cent in the United States, and 21 per cent in the United Arab Emirates.

“When we talk about malnutrition, we are no longer just talking about underweight children,” said UNICEF Executive Director Catherine Russell. “Obesity is a growing concern that can impact the health and development of children. Ultra-processed food is increasingly replacing fruits, vegetables and protein at a time when nutrition plays a critical role in children’s growth, cognitive development and mental health.”
