The World Health Organization (WHO) has published its first global guidelines on the clinical management of obesity in children and adolescents. The document establishes common standards for healthcare systems as excess weight affects 170 million young people aged 5 to 19 worldwide, amid rising use of injectable weight-loss medications.

Age-specific clinical standards

The guidance sets distinct parameters based on age. For children up to 9 years old, the UN agency advises against weight-loss drugs and bariatric surgery, directing care toward nutrition, physical activity, and family involvement. For adolescents aged 10 to 19, pharmaceutical treatments are recommended only as a last resort when supervised lifestyle interventions fail to control complications. Bariatric surgery remains limited to adolescents with severe obesity.

In Brazil, the international guidance provides a clinical framework for the country's public healthcare network, the Unified Health System (SUS), as well as private pediatric practices. Local data shows significant exposure to the condition: health screenings in public schools in Brasília revealed that one in three students was overweight, reflecting broader shifts in dietary patterns across urban centers.

Brazilian medical authorities emphasize that environmental factors must accompany clinical responses. Fabíola Suano, head of the nutrology department at the Brazilian Society of Pediatrics (SBP), noted that interventions need to address sedentary habits, screen exposure, and barriers to outdoor activity. The pediatric group advocates for public measures that reduce ultra-processed food consumption in school environments while supporting accessible sports facilities.
