Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Cardiovascular disease (CVD) and diabetes occur commonly among Native Americans (NA), and are leading causes of death among northern US NAs. Moreover, low vitamin D status occurs commonly in this same population. An increasing amount of evidence indicates a correlation between low vitamin D status and CVD and diabetes by contributing to a heightened pro-inflammatory environment within the endothelial lining of blood vessels leading to atherosclerotic disease, and an impaired sensitivity to insulin leading to diabetes. Our fundamental hypothesis is that low vitamin D status is a risk factor for CVD by causing a proinflammatory milieu, thereby leading to endothelial dysfunction. Additionally, the investigators hypothesize that vitamin D supplementation will reduce inflammation, thereby restoring endothelial function and ultimately reducing CVD risk.
