Vitamin D Supplementation in Psychiatric Illnesses
Effect of Vitamin D Supplementation on the Metabolic Abnormalities of Second Generation Antipsychotics in Children and Adolescents

Children and adolescents with psychiatric illnesses who are treated with medications called second generation antipsychotic agents (SGA) often gain excessive weight during their treatment with these medications. This weight gain may result in the development of features of the metabolic syndrome or frank diabetes mellitus. There is no consensus on the best way to prevent these complications. The investigators' hypothesis is that daily vitamin D supplementation in these patients will result in decreased levels of the markers of metabolic syndrome with associated reduction in waist circumference.

In this 8-week open label trial, we will enroll 10 subjects who fulfill the Inclusion Criteria.
