WINSTON-SALEM Rates of severe childhood obesity have tripled in the last 25 years, putting many children at risk for diabetes and heart disease, according to a report in Academic Pediatrics by an obesity expert at Brenner Children's Hospital, part of Wake Forest University Baptist Medical Center.
"Children are not only becoming obese, but becoming severely obese, which impacts their overall health," said Joseph Skelton, M.D., lead author and director of the Brenner FIT (Families in Training) Program. "These findings reinforce the fact that medically-based programs to treat obesity are needed throughout the United States and insurance companies should be encouraged to cover this care."
The research was published on-line and will appear in the September print edition. Skelton and colleagues compared data from the National Health and Nutrition Examination Survey (NHANES). They looked at the prevalence of obesity and severe obesity in a study population of 12,384 children, representing approximately 71 million U.S. children ages 2 to 19 years.
Severe childhood obesity is a new classification for children and describes those with a body mass index (BMI) that is equal to or greater than the 99th percentile for age and gender. For example, a 10-year-old child with a BMI of 24 would be considered severely obese, Skelton said, whereas in an adult, that is considered a normal BMI. An expert committee convened by the American Medical Association, the Centers for Disease Control and the Department of Health and Human Services proposed the new classification in 2007.
The research by Skelton and colleagues is the first of its kind to use the new classification and detail the severity of the problem. They found that the prevalence of severe obesity tripled (from 0.8 percent to 3.8 percent) in the period from 1976-80 to 1999-2004. Based on the data, there are 2.7 million children in the U.S. who are considered severely obese.
