Vitamin D status of gastrostomy-fed children with special needs: a cross-sectional pilot study.

Aim: To assess the vitamin D status of gastrostomy-fed children.

Methods: Vitamin D status was measured in 32 children aged five to 16 years recruited from special schools in Manchester, UK (53° 48 N). All children were receiving a nutritionally complete, commercially prepared enteral feed via gastrostomy, and had been established on this regimen for over 12 months.

Vitamin D status and muscle function in post-menarchal adolescent girls.

Context: There has been a resurgence of vitamin D deficiency among infants, toddlers, and adolescents in the United Kingdom. Myopathy is an important clinical symptom of vitamin D deficiency, yet it has not been widely studied.

Objective: Our objective was to investigate the relationship of baseline serum 25 hydroxyvitamin D [25(OH)D] concentration and PTH with muscle power and force.
