Study Summary
The purpose of this research study is to determine whether taking vitamin D, every day, over a 12 week period will improve the vitamin D status, risks for poor heart health, risks for developing type 2 diabetes, and/or muscle strength in overweight, African American teenagers with low vitamin D levels.
Primary Outcome
The analysis will be an intention-to-treat method in which subjects are assumed to obtain all vitamin D supplements from the study and from no other sources, and all subjects are assumed to comply with their assigned dose and daily use. For the main contrasts of interest (5000 IU vs 1000 IU doses as well as serum 25OHD concentrations), we propose a longitudinal mixed effects model with time measurements at 0 and 12 weeks.
Interventions
- DIETARY_SUPPLEMENT Cholecalciferol
