Dec. 5, 2007 -- Overweight children grow into adults at high risk of early
heart disease and early heart death, a long-term Danish study shows.
The finding isn't a prediction -- it's hard data from very long-term data on
10,235 men and 4,318 women born in Copenhagen, Denmark, from 1930 through
But given the size of the ongoing
obesity epidemic, the findings predict a huge wave of future heart
Researchers Jennifer L. Baker, PhD, and colleagues at Copenhagen's Center
for Health and Society painstakingly compiled records for virtually every
schoolchild in the city and matched them with national health records.
The bottom line: After the age of 7, overweight children have an increased
risk of adult heart disease. The higher a
child's body mass index -- BMI,which relates weight to height
-- the higher that child's risk of becoming an adult with heart
"What we found was at the age of 7, for both boys and girls, the risk
was moderate," Baker tells WebMD. "By age 13, the risk increased
A child does not have to be hugely obese to be at increased risk.
"We compared the average 13-year-old boy, who weighed 96 pounds, to a
heavier boy of the same height who weighed 121 pounds," Baker says.
"Even for a normal-weight boy, there is a one-in-nine risk of heart disease
by age 60. For the heavier child, this risk becomes at least one in six. We
find that highly significant."
Pediatric cardiologist Tom Kimball, MD, of Cincinnati Children's Hospital,
says the findings are a warning that parents must take childhood weight
problems seriously -- even in young children.
"This is not an adult problem. It is a kid problem," Kimball tells
WebMD. "This study has a big message for parents."
During the 46 years of the study, an overweight child's risk of becoming an
adult with a sick heart did not change much. The problem did not so much appear
to be the modern diet as the simple fact of being overweight as a child.
Tsunami of Heart Disease Predicted
Modern diets being what they are, child obesity is increasing at an alarming
pace. Overweight children tend to become overweight
teens, and overweight teens tend to become adults with heart disease.
