Bone Health and Vitamin D in Paediatric Obesity Care

Centre d'apprentissage en ligne ECN

Description

This EASO COMs webinar explored bone health and vitamin D in children and adolescents living with obesity, with a focus on practical assessment and multidisciplinary care. Expert speakers examined how excess adiposity affects skeletal development, fracture risk, and vitamin D status, alongside approaches to identifying and managing nutritional deficiencies. The session highlighted the importance of supporting growth, bone health, and muscle function across obesity treatment pathways. Full programme and speaker affiliations here.

Bone Health in Paediatric Obesity

Bone health is an important component of comprehensive paediatric obesity care. Excess adiposity can affect the developing skeleton through mechanical loading, chronic inflammation, and altered hormonal signalling. Greater body weight does not necessarily protect against fractures, and childhood obesity may be associated with skeletal deformities, musculoskeletal pain, and longer recovery following fracture surgery.

 

Assessment and Early Recognition

Assessment should consider growth velocity, pubertal development, bone and joint pain, fracture history, nutritional intake, and physical function. Persistent pain, recurrent low-trauma fractures, or progressive lower limb deformities may require further investigation or specialist assessment. The session highlighted the importance of recognising conditions such as slipped capital femoral epiphysis and Blount disease.

 

Vitamin D Status and Clinical Interpretation

Low vitamin D concentrations are common in children and adolescents living with obesity, reflecting factors including distribution across a larger body volume, storage within adipose tissue, and reduced sun exposure. Although associations with insulin resistance and metabolic dysfunction have been reported, evidence that supplementation improves metabolic outcomes remains inconsistent. The clinical priority is to correct deficiency appropriately; additional benefits from raising concentrations beyond sufficiency have not been established.

 

Individualised Vitamin D Management

Routine preventive supplementation and targeted biochemical assessment serve different purposes. Decisions about testing, supplementation, and follow-up should reflect clinical findings, additional risk factors, relevant national guidance, and treatment response. The speakers emphasised that vitamin D thresholds and requirements vary, and that adherence and individual circumstances are central to effective management.

 

Intégration dans les filières de soins de l'obésité

Obesity treatment should support continued growth, pubertal development, and bone mineral accrual. Balanced nutrition, adequate calcium and protein, appropriate vitamin D management, and tailored physical activity help protect bone and muscle health. Bariatric surgery requires long-term nutritional monitoring and supplementation support. During GLP-1 receptor agonist treatment, reduced food intake may increase nutritional risks, although direct evidence on paediatric bone outcomes remains limited.

Orientations futures et prochaines étapes

  • Strengthen assessment of skeletal symptoms, growth, and physical function within paediatric obesity care pathways
  • Support individualised vitamin D management informed by clinical risk and relevant national guidance
  • Integrate nutritional support and tailored physical activity to preserve bone and muscle health during treatment
  • Improve supplementation adherence and long-term follow-up after metabolic and bariatric surgery
  • Expand evidence on nutritional requirements and bone health during GLP-1 receptor agonist treatment in adolescents
