THURSDAY, Sept. 1 (HealthDay News) -- Black Americans are more
likely than whites to have a condition in which the kidneys spill
protein into the urine, which may help explain why blacks are four
times more likely than whites to develop kidney failure, a new
Emory University researchers analyzed data from about 28,00
people (40.5 percent blacks, 59.5 percent whites) in the United
States and found that 133 of them developed kidney failure after an
average follow-up of 3.6 years.
There were 96 cases of kidney failure among blacks and 37 cases
Kidney failure was more common among people who excreted large
amounts of protein in their urine, and blacks were more likely than
whites to have this problem.
The researchers suggested a number of reasons why blacks are
more likely to excrete more protein in their urine, including:
blood pressure and other heart-related issues; smoking, vitamin D
levels, obesity, income, genetic differences and birth weight.
All these factors can impact kidney health.
Treating urinary protein excretion could reduce racial
disparities in kidney failure rates and also slow the rate of
progression to kidney failure among patients of all races, the
The study appears in an upcoming issue of the
Journal of the American Society of Nephrology.
