Washington: A new study has found that vitamin D is a significant factor determining the difference in blood pressure between Blacks and Whites and the level of hypertension between the two, living in U.S.It is quite evident that high blood pressure is more common amongst Blacks than Whites and persons with darker skin generally produce less vitamin D, primarily at higher latitudes where UV radiation is less intense and the climate is cooler, leading to less skin exposure.
"Our study adds to the growing body of evidence showing that low levels of vitamin D among Blacks contribute to cardiovascular disparities. We also know that blood pressure is highest among Blacks living in the US, where UV exposure is low. Taken together, these findings point towards vitamin D deficiency as a potential contributor to higher rates of vascular dysfunction, here hypertension among Blacks living in the US. Further, work is required to determine whether vitamin D supplementation could reduce these racial disparities."The study has been published in the Journal of General Internal Medicine. ANI
