CDC
Issues Diabetes Warning for Children
NEW
ORLEANS (AP) -- 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. |
