Extreme Obesity Found in 6.4% of Children, Kaiser Study Finds

Bloomberg reports:

Extreme obesity affects about 6.4 percent of children, according to a Kaiser Permanente study that suggests overweight kids are getting even heavier.

More children are graduating from “obese” to “extremely obese,” according to the study, the first to evaluate kids using U.S. guidelines published last year that distinguish among degrees of obesity. The report drew from the electronic medical records of 710,949 patients ages 2 to 19 years old enrolled in 2007-2008 in Kaiser health programs in Southern California.
