June 26, 2007 -- The number of U.S. children with chronic health conditions has risen dramatically in the past four decades, according to a new report.
The new research shows that kids will become so disabled their quality of life will suffer, and their needs will tax our health care and welfare programs in the future.
"We have 80 million children in America today, and about 8%, or 6.5 million children and adolescents, have chronic conditions that interfere with regular daily activities," says James M. Perrin, MD, professor of pediatrics at Harvard Medical School and Massachusetts General Hospital, Boston. He is the lead author of the report, a commentary that appears in the June 27 issue of the Journal of the American Medical Association. The issue is devoted to the topic of pediatric chronic disease.?
If children with chronic conditions not severe enough to be disabling are counted, chronic conditions affect about 18% of American teens and children in all, Perrin says.
The new numbers, Perrin says, represent a "huge increase" from previous generations. In 1960, for instance, fewer than 2% of U.S. children and teens had a chronic health condition.
Using multiple data sources, Perrin and his co-authors found that:
"People have been very aware of the obesity epidemic [among children] in the past decade and aware of the asthma increase, but no one has put it together the way we have," Perrin tells WebMD. "I think we are the first to look at the whole picture together."
The new commentary, he says, is meant to provide a comprehensive view of the status of the problem. "This is in many ways meant to be a wake-up call," he says.
The researchers defined a chronic health condition as one that lasts 12 months or longer or at the time of diagnosis is expected to last that long. The 1960 research finding that fewer than 2% of children and teens were noted by their parents to have a limit in activity due to a health condition that lasted more than three months.
All three conditions -- asthma, obesity, and ADHD -- have been linked to genetic influences, Perrin says, yet genetic factors can't totally explain the rise in the problems.
He points also to social, family, and environmental changes, such as a rise in working parents with less time to nurture their children, more stress on parents, increased use of television and other media and computers, and decreased opportunities for physical activity.
Another factor that may play a role, the researchers say, is the rise in very low-birth-weight babies, who have been found to be at higher risk for obesity, ADHD, and perhaps asthma.
Dietary changes -- increases in calories and portion size, as well as the abundance of sugary beverages -- also affect the rise in obesity, he says.
As today's children and teens move into young adulthood, Perrin sees a huge impact on their need for health care as well as social services if they become disabled. "I think we are going to see a doubling or tripling of health care costs," he says.
"These are people who are going to have much less of a good quality of life and good future," he says. Young people who are obese have a higher risk of getting diabetes and cardiovascular disease, he tells WebMD, and children with severe asthma can become disabled even as teens.
ADHD, he adds, is probably in large part due to genetics but may have environmental factors playing a role.
