Sources: 67. Developments: 3. The World Health Organization (WHO) has released its first global guidelines for the integrated management of obesity in children and adolescents aged 0 to 19. This follows reports that obesity prevalence in this age group has quadrupled from 2% in 1990 to 8% in 2024, affecting approximately 170 million young people. Of these, an estimated 70 million are aged 5–9 and 100 million are adolescents. The WHO classifies obesity as a chronic and recurring disease. The guidelines prioritize lifestyle-based interventions, such as tailored dietary plans, regular physical activity, and behavioral changes involving caregivers, over medical or surgical solutions. The organization emphasizes that the foundation of care should be a supportive environment. For children aged 0 to 9, the WHO does not recommend pharmacological treatments, bariatric surgery, or weight-loss devices due to concerns regarding long-term safety and efficacy, specifically citing a lack of evidence regarding long-term effects on growth and mental health. For adolescents aged 10 to 19, the WHO suggests that approved medications, such as GLP-1 analogues, may only be considered if supervised, multimodal lifestyle programs fail to produce results for at least six months. Bariatric surgery is reserved for severe cases under strict clinical and psychological conditions. The organization also highlighted the mental health implications of obesity, including risks of stigma, bullying, depression, and anxiety. In Brazil, regulatory body Anvisa has approved Novo Nordisk’s Wegovy (semaglutide) for patients aged 12 and older, provided it is used alongside lifestyle changes. While clinical studies like STEP TEENS have demonstrated significant BMI reductions in adolescents, and research such as the STEP Young study shows efficacy in younger children, regulatory approval for those under 12 is not yet in place in Brazil. ## Claims - Weight-loss drugs, surgery, and devices are prohibited for children under the age of 10.
