[Editorial] Childhood obesity tops underweight, says UNICEF

For the first time in recorded history, children are more likely to be obese than underweight. UNICEF's new child nutrition report shows the prevalence of obesity among children and adolescents aged 5–19 years rising in 2025 to 9·4%, surpassing the 9·2% of children with underweight. The crossover corresponds with a shift in childhood food environments, the report explains: unhealthy food and drink is ever cheaper, more convenient, and aggressively marketed in all the right (wrong) places—at schools and corner shops, as well as online.
