Objectives
To document the prevalence of hypovitaminosis-D in children with intellectual and movement disorders and to identify the risk factors in vitamin D deficient children.
Methods
This is a cross-sectional study on 90 children with neurodevelopmental disabilities. The prevalence of hypovitaminosis-D and the risk factors such as sun exposure, age-appropriate mobility, diet, skin color and anti-epileptic medications were examined in children with cognitive disorders and movement disorders.
Results
The mean serum vitamin D level in children with cognitive disability (n = 46) was found to be 26.7 ± 16.3 ng/L and in the children with movement disability (n = 44) it was 27.9 ± 10.5 ng/L. Though the risk factors were found in greater numbers in children in the deficient group (vitamin D < 30 ng/L), the difference between the two groups was not significant. Of the 90 children, 86 (95.5%) had at least one sign of vitamin D deficiency. Lowest levels of vitamin D were seen in autistic spectrum disorder and learning disabilities in the Cognitive Disability group and hemiplegia in the Movement Disability group.
Conclusions
The prevalence of vitamin D deficiency in children with neurodevelopmental disabilities was 72.2%, with 76.1% in the cognitive disability group and 68.2% in the movement disability group. The risk factors were more common in vitamin D deficient children.
