Low Levels of Vitamin D Explain the Racial Differences in Hypertension!
Dark skinned people produce less vitamin D, which could be the factor contributing to high blood pressure in them when compared to white skinned people according to the results of a study conducted by the University of Rochester and published in the Journal of General Internal Medicine.
Hypertension or high blood pressure is more common and severe in black people than whites.
According to Kevin Fiscella, the lead author, through this study they have found a significant role of vitamin D in controlling blood pressure. Minor differences in blood pressure could lead to stroke and heart disease and is the cause of deaths in black skinned people.
The study was a data analysis from the year 2001-2006 and was conducted on 5100 non-Hispanic whites and 2000 blacks all of them aged 20 or above.
It was found that 61% black people had low vitamin D levels as opposed to 11% of whites in the lowest 1/5th of the sample population. On the contrary, as less as 2% of black people as opposed to 25% whites had high vitamin D levels in the highest sample population.
