Official title
Comparison of Two Standard High-dose Treatment Regimens for Vitamin D Deficiency in Minority Adolescents: Associations of Vitamin D Repletion With Changes in Markers of Musculoskeletal, Cardiometabolic, and Immune Function
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 \[25(OH)D level \<20 ng/ml\] by assessing change in 25(OH)D levels before and after 8 weeks of treatment. To compare the effects of vitamin D repletion \[25(OH)D level \>20 ng/mL\] 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.
