Childhood obesity blamed for increase of illnesses

— Overweight children are being hospitalized at dramatically rising rates for diabetes, sleep apnea and other diseases that obesity causes or worsens.

Obesity accounts for a tiny proportion of all child hospitalizations, scientists say. But the Centers for Disease Control and Prevention reported Wednesday that "a disturbing increase" in the numbers has made hospital costs related to childhood obesity more than triple in the past 20 years, reaching $127 million.

Doctors have long warned that childhood obesity has become epidemic. But the new research is among the first to show how much more is at stake than fat children growing into fat adults obesity can seriously sicken them now.

"When you show a parent a growth chart and point out the child is overweight, it doesn't mean very much unless the child's self-esteem is affected," said CDC lead researcher Dr. William Dietz.

About 13 percent of children and adolescents are overweight or obese, more than double the number two decades ago. Experts blame television, computer games, lack of safe playgrounds and other factors that encourage kids to be sedentary plus more access to super-sized portions of high-calorie foods.

At the same time, more children are suffering Type 2 diabetes, a dangerous disease that once struck mostly in middle age. Obesity also can worsen asthma and spark gallbladder disease. People even can die from obesity-caused sleep apnea, Dietz notes, when fat in the back of the throat combines with large tonsils to block the airway.

CDC researchers culled hospital discharge records, comparing obesity-related hospitalizations of 6- to 17-year-olds between 1979 and 1981 with those from 1997 through 1999.

Diabetes diagnoses nearly doubled, accounting for 2.36 percent of child hospitalizations in the late '90s vs. 1.43 percent in the late '70s, they reported Wednesday in the journal Pediatrics.

Diagnoses of obesity alone tripled to reach 1 percent of hospitalizations.

Other obesity-related hospitalizations were more rare but rising rapidly sleep apnea rose fivefold and gallbladder disease tripled. Asthma cases complicated by obesity rose 40 percent.

The study may surprise parents, but not obesity specialists who called it high time someone pointed out the growing danger to youngsters.

"The kids who are fat are getting really fatter," said Dr. Nazrat Mirza of Children's National Medical Center, who has patients as young as 5 with obesity-caused sleep apnea.

The study "represents just the tip of the iceberg," she said because doctors often don't record obesity on hospital discharge records. That's because insurance companies don't pay to treat it until the child comes down with a formal illness, she complained.

The government brought together star athletes Dominique Dawes, Herschel Walker and Martina Navratilova Wednesday to publicize the study and urge kids to stay slim by simply getting active.

"Get up and go outdoors," urged Education Secretary Rod Paige. "Swim, hike, ... dribble, slam-dunk. Do whatever, just move your body."
