Abstract
Aim
In an earlier study we identified severe Vitamin D deficiency as a problem in institutionalised children with cerebral palsy (CP), which resulted in rickets and a high incidence of fractures. The purpose of this study was to establish whether a cohort of non-ambulatory children with CP, living at home, presented with Vitamin D deficiency.
Method
The participants were a consecutive sample (N=100) of non-ambulatory children with CP attending a CP outpatient clinic. Their ages ranged from 2 to 15 years (mean 5.8, SD 3.3 years). There were 57 males and 43 females. Nineteen were on Level IV of the Gross Motor Function Classification System (GMFCS), and 81 were on Level V. 66% were on anticonvulsant therapy (ACT). Basic demographic data was collected, and measurements included blood sample analysis and wrist radiographs. There was radiographic evidence of osteopenia and delayed ossification of the carpal bones.
Results
Three participants had Vitamin D deficiency rickets confirmed by wrist changes and serology. There was a significantly higher level of Alkaline Phosphatase (p=0.04) in children on ACT than in those who did not receive ACT. Preliminary results show that one third of the children had Vitamin D deficiency.
Conclusion
Non ambulatory children with CP are at risk of developing rickets. We recommend regular exposure to sunlight or Vitamin D supplementation as preventative measures.
