CDC
Issues Diabetes Warning for Children
NEW ORLEANS -
One in three U.S. children born in 2000 will become diabetic unless
many more people start eating less and exercising more, a scientist
with the Centers for Disease Control and Prevention warns.
The odds are worse for black and
Hispanic children: nearly half of them are likely to develop the
disease, said Dr. K.M. Venkat Narayan, a diabetes epidemiologist
at the CDC.
"I think the fact that the diabetes
epidemic has been raging has been well known to us for several
years. But looking at the risk in these terms was very shocking
to us," Narayan said.
The 33 percent lifetime risk is
about triple the American Diabetes Association's current estimate.
The implications are frightening.
Diabetes leads to a host of problems, including blindness, kidney
failure, amputation and heart disease, and diabetics are getting
younger and younger.
Including undiagnosed cases, authorities
believe about 17 million Americans, nearly 6 percent of the U.S.
population, have diabetes today.
If the CDC predictions are accurate,
some 45 million to 50 million U.S. residents could have diabetes
by 2050, said Dr. Kevin McKinney, director of the adult clinical
endocrinological unit at the University of Texas Medical Center
in Galveston.
"There is no way that the medical
community could keep up with that," he said.
McKinney, who was not part of the
study, said Narayan's procedures are valid and the estimates,
being presented Saturday to the American Diabetes Association,
are probably all too likely.
Diabetes, a disease caused largely
by obesity and lack of exercise, has been an increasing worry
for decades. From the mid-1960s to the mid-'90s, the number of
cases tripled.
The number of diagnosed cases rose
by nearly half in just the past 10 years, hitting 11 million in
2000, and is expected to rise an additional 165 percent by 2050,
to 29 million, an earlier CDC study by Narayan and others found.
"These estimates I am giving you
now are probably quite conservative," Narayan said in an interview
before the diabetes association's annual scientific meeting here.
Narayan said it would be difficult
to say whether undiagnosed cases would rise at the same rate.
If they did, that could push the 2050 figure to 40 million or
more.
Doctors had known for some time
that Type 2 diabetes what used to be called adult-onset
diabetes because it typically showed up in middle-aged people
is on the rise, and that patients are getting younger.
Nobody else had crunched the numbers
to look at current odds of getting the disease, Narayan said.
Overall, he said, 39 percent of
the girls who now are healthy 2 1/2- to 3-year-olds and 33 percent
of the boys are likely to develop diabetes, he said.
For Hispanic children, the odds
are closer to one in two: 53 percent of the girls and 45 percent
of the boys. The numbers are about 49 percent and 40 percent for
black girls and boys, and 31 percent and 27 percent for white
girls and boys.
To reach his estimates, Narayan
used data from the annual National Health Interview Survey of
about 360,000 people from 1984-2000, from the U.S. Census Bureau
and from a previous study of diabetes as a cause of death.
Globally, the World Health Organization
has estimated that by 2025, the number of people with diabetes
worldwide will more than double, from 140 million to 300 million.
"They estimated that by 2025, there
would be close to 60 million people with diabetes in India alone.
That's about the size of Great Britain or France," Narayan said.
It doesn't have to happen.
Type 2 diabetes can be prevented
or delayed by losing weight, exercising and following a sensible
diet.
A study two years ago found that
walking 30 minutes a day most days of the week and losing a little
weight helped the people most likely to get it cut their risk
58 percent.
The U.S. Department of Health and
Human Services used that information last fall in its "Small Steps,
Big Rewards" campaign against diabetes.
