The Centers for Disease Control and Prevention says 1 in 8 preschoolers are obese, which is 12 percent.
Kids who are overweight or obese as preschoolers are five times as likely as normal-weight children to be overweight or obese as adults.
CDC officials studied all 50 states from 2008 to 2011, and rates in Wisconsin did not change during the study.
Pediatricians say it only takes a little time to help small kids get moving.
“Try to -- 30 to 60 minutes a day -- do some sort of activity when you’re moving, even if it’s inside dancing or playing with balls inside, something where they’re active,” said Dr. Sara Kreckman, a Meriter pediatrician.
The CDC data coincides with a new study that shows just one sugary drink can put preschoolers on a path to obesity.
Research in the Journal Pediatrics looked at 9,600 young children and found 4- and 5-year-olds who drank one or more sugar-sweetened beverages a day were more likely to be overweight or obese.
