Study 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.

  4. Subjects with known history of parathyroid disorder,
  5. Subjects with acquired or congenital disorders of vitamin D metabolism,
  6. Subjects on calcium and vitamin D replacement therapy, such as calcium carbonate, or ergocalciferol, or cholecalciferol,

What researchers measure

Primary outcomes

  1. Change in Weight

    Time frame: Baseline and 8 weeks

Secondary outcomes

  1. Insulin Resistance as Measured by HOMA-IR at Baseline and Post-treatment

    HOMA-IR: 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

    Time frame: Baseline and 8 weeks

  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
