Kidney Failure Rates Dip, Numbers Growing With
Older Population
Age 75 up group now 26% of total, troubling racial
disparities persist
Oct. 11, 2005 - After 20 years of annual increases
from 5 to 10 percent, rates for new cases of kidney failure have
stabilized, according to new research from the National Institute of
Diabetes and Digestive and Kidney Diseases (NIDDK) of the National
Institutes of Health. The numbers of the oldest population, however,
continue to climb and dramatic racial disparities persist.
In 2003, the rate for new cases of kidney failure
was 338 per million population. This is down slightly from 2002 and
continuing a four-year trend, finally allowing researchers to be
cautiously optimistic that rate decreases have not happened by chance.
The incident rate for those 65 to 74, however, was 1,435 and for those
75 and over the rate was 1,687.

The average annual increase has been less than 1
percent since 1999, compared to an average 5 percent in the previous
decade, according to research published recently by NIDDK’s U.S. Renal
Data System (USRDS) at
www.usrds.org and being presented next month at the annual
scientific meeting of the American Society of Nephrology.
Diabetes and high blood pressure remain the leading
causes of kidney failure, accounting for 44 percent and 28 percent of
all new cases, respectively. The most striking trends were found in
diabetes, where rates for new cases in whites under age 40 were the
lowest since the late 1980’s, in stark contrast to rates for their
African American counterparts, which have not budged.
|
In the last four years the USRDS has
noted a continued growth in the number of treated patients, but
a slowing of the incident rates. More than 100,000 new patients
began therapy for ESRD in 2003 (2 percent greater than in 2002),
while the prevalent dialysis population reached nearly 325,000
(3.8 percent higher), and the prevalent transplant population
grew to nearly 130,000 (5.6 percent higher). Both prevalent
populations have doubled since 1988, while the number of
incident patients has grown 150 percent. |
