Obesity Phenotyping in Children and Adolescents: Next Steps Towards Precision Medicine in Pediatric Obesity

Area of Science:

• Pediatric Endocrinology
• Obesity Medicine
• Metabolic Disorders

Background:

• Pediatric obesity is a growing, complex health issue with diverse treatment responses.
• Current interventions for childhood obesity often face challenges in achieving sustained weight reduction.
• Understanding factors influencing treatment variability is key to improving outcomes.

Purpose of the Study:

• To review evidence on outcome variability in pediatric obesity interventions.
• To examine biological, metabolic, behavioral, environmental, and psychosocial factors affecting treatment response.
• To highlight the need for obesity phenotyping in pediatric populations.

Main Methods:

• Systematic review of current literature on pediatric obesity interventions.
• Analysis of factors influencing treatment effectiveness across lifestyle, pharmacologic, and surgical approaches.
• Comparison with adult obesity phenotyping strategies.

Main Results:

• Significant heterogeneity exists in treatment responses for pediatric obesity.
• Limited data are available on obesity phenotyping in children and adolescents.
• Adult phenotyping models show promise but require pediatric validation.

Conclusions:

• Personalized medicine approaches are essential for effective pediatric obesity management.
• Developing pediatric-specific obesity phenotypes can guide tailored interventions.
• Addressing phenotyping gaps will enhance treatment selection and long-term outcomes.
