A 10-ng/mL decrease in 25(OH)D levels was associated with an increased risk of coronary heart disease events in whites (HR 1.26, 95% CI 1.06-1.49) and those with Chinese ancestry (HR 1.67, 95% CI 1.07-2.61), according to Ian de Boer, MD, of the University of Washington in Seattle, and colleagues.
But a similar relationship was not seen among blacks (HR 0.93, 95% CI 0.73-1.20) and Hispanics (HR 1.01, 95% CI 0.77-1.33), the investigators reported in the July 10 issue of the Journal of the American Medical Association.
A couple of years ago I asked my primary care physician to check my Vitamin D level. We were both surprised to discover the fact I was Vitamin D deficient. Since then I’ve been on daily Vitamin D supplementation of 5000iu.
Simple blood test. Just do it.
The researchers advised caution in interpreting the results in the Chinese and Hispanic participants because of the low sample sizes.
I’m still going to take my supplement.
