Brief Summary:
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.

Arm Intervention/treatment
Experimental: Vitamin D Drug: Ergocalciferols
2000 international units by mouth daily for 8 weeks.
Other Name: Drisdol

Primary Outcome Measures :
  1. Change in Weight [ Time Frame: Baseline and 8 weeks ]

Secondary Outcome Measures :
  1. Insulin Resistance as Measured by HOMA-IR at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]


    It is calculated multiplying fasting plasma insulin (FPI) by fasting plasma glucose (FPG), then dividing by the constant 22.5, i.e. HOMA-IR = (FPI×FPG)/22.5

  2. Changes in Serum Levels of C-reactive Protein. [ Time Frame: Baseline and 8 weeks ]
  3. HDL-cholesterol at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]
  4. LDL-cholesterol at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]
  5. Total Cholesterol at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]
  6. Triglycerides at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]
  7. Adiponectin at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]
  8. Leptin at Baseline and Post-treatment [ Time Frame: Baseline and 8 weeks ]
