Treatment of Vitamin D Deficiency in Predominantly Hispanic and Black Adolescents: A Randomized Clinical Trial.
Summary
To compare the efficacy of two high dose vitamin D3 regimens (5,000 IU daily vs. 50,000 IU weekly) used clinically for the treatment of vitamin D deficiency versus a low dose of vitamin D3 used for supplementation (1,000 IU daily) in a clinical sample of predominantly Hispanic and black adolescents with vitamin D deficiency [25(OH)D level 20 ng/mL] on selected musculoskeletal, cardiometabolic and immune markers in predominantly Hispanic and black adolescents with vitamin D deficiency [25(OH)D level < 20 ng/mL].
Hypothesis 1: Increase in vitamin D level will be associated with improvement in musculoskeletal, cardiometabolic, and immune markers including blood pressure, waist circumference, musculoskeletal symptoms, asthma severity and hand-grip strength.
