Researchers find obesity increasing among U.S. kindergartners, except for the wealthy.
Since 1988 obesity rates have increased among children who enter kindergarten in the United States. The exception, according to research published in JAMA Pediatrics, appears to be among the wealthy.
The leveling out of obesity rates among children that was reported last year by the U.S. Centers for Disease Control and Prevention (CDC) appears to not extend to everyone.
“When you start splitting children up by different socioeconomic groups, then you find the increase is rather quite large among the lower socioeconomic group,” said Ashlesha Datar of the University of Southern California in Los Angeles.
Data from over 17,000 children entering kindergarten in 1998 was compared by Datar and her colleagues to data from more than 15,500 children who entered kindergarten in 2010.
There was no difference in rates between boys and girls, but there was a difference in the five groups of children separated by family income.
