Clinical Report: Improving Obesity Care for Children and Adolescents

Overview

WHO issued its first guidelines on obesity treatment for children younger than 10 years and adolescents aged 10–19 years on 7 October 2026. The guidelines advise against pharmacological treatment in children and reserve medication for adolescents until alternative treatment options have been exhausted; the source describes evidence for pharmacotherapy as low quality and evidence for diet or exercise approaches as very low. The article highlights substantial evidence gaps, including the need for research that reflects young people’s real-world environments and longer-term assessment of medication safety.

Background

Childhood and adolescent obesity is increasing: the proportion of adolescents globally classified as overweight rose from 8% in 1990 to 20% in 2024. The source reports that 70% of adolescents with obesity remain affected at age 30 and associates youth obesity with chronic conditions, immediate health risks, stigma, depression, and lower educational attainment. Contributors include sedentary lifestyles, high-fat and high-sugar food consumption, socioeconomic circumstances, and parental obesity. The article notes that access to exercise and nutritious food can constrain the effectiveness of individual-level advice.

Data Highlights

Key Findings

• WHO’s inaugural guidelines address obesity treatment in children younger than 10 years and adolescents aged 10–19 years.

• The guidelines advise against pharmacological therapies, including GLP-1 receptor agonists, for children; medication is reserved for adolescents after alternative treatment options have been exhausted.

• The article reports that evidence supporting pharmacotherapy is low quality, while evidence for diet or exercise approaches is very low quality.

• Globally, adolescent overweight prevalence increased from 8% in 1990 to 20% in 2024; the article also reports that 70% of adolescents with obesity remain affected at age 30.

• The article identifies environmental and social constraints on diet and exercise interventions, including limited access to exercise space and affordable nutritious food, and calls for research that better reflects real-world settings.

• The article states that evidence on GLP-1 receptor agonists in adolescents remains sparse and calls for extended follow-up to assess safety during puberty; it also notes concerns about weight regain after discontinuation, unsupervised access, and possible effects on eating disorders and body dysmorphia.

Clinical Implications

The article describes WHO’s approach as non-pharmacological treatment for children younger than 10 years and conditional pharmaceutical treatment for adolescents after alternative options have been exhausted. It identifies the need for care and research to account for young people’s access to exercise and nutritious food, and for longer-term safety follow-up of pharmacotherapy through puberty.

Conclusion

The WHO guidelines provide an initial framework for treating obesity in children and adolescents, while the article emphasizes that evidence remains limited. Further research is needed on real-world interventions and the long-term safety and consequences of pharmacotherapy in young people.
