Minnesota made the list for states that showed a significant decline in the percentage of low-income children who are obese.
The findings are part of the latest information compiled by the Centers for Disease Control and Prevention in Atlanta. The information is from its Pediatric Nutrition Surveillance System, with data collected between the years 2008 and 2011.
The Associated Press report the findings represent the first evidence of a national decline in childhood obesity. In 18 states, there were at least slight declines in obesity in low-income preschoolers. The biggest declines were in Florida, Georgia, Missouri, New Jersey and South Dakota. The report didn't answer why some states improved while most others held steady.
Previous national statistics show obesity rates have been rising for decades and recently were essentially flat. Still, 1 in 8 preschoolers are obese.
