Childhood Obesity Rate May Be Undercounted
The obesity rate among American kids may actually be higher than the 18 percent of children the Centers for Disease Control currently classifies as obese, according to an analysis published in the journal Pediatric Obesity. As many as 25 percent of obese or overweight kids may not be counted because the tally is based on the body mass index (BMI), a calculation that researchers say is flawed because children's height and weight change rapidly as they grow--and not always in proportion with each other.
Other recent research has linked everything from sleep deprivation to weight-based name calling with an elevated risk of childhood obesity. Research released earlier this year had claimed a significant drop in the childhood obesity rate in the U.S., but subsequent research actually showed a sharp increase in the number of severely obese kids.
