LA CROSSE, Wis. (WKBT) -

New research from the Journal of American Study is showing two different sides of obesity in America.

The study is showing a drop in obesity rates among young children. In the past decade, obesity rates in 2 to 5 year olds decreased from 14% in 2003 to 8% in 2012.

On the other hand, obesity rates haven't changed much for adults. One in three people over the age of 20 are still obese. Also, the study found there has been a 20% increase in obesity for women 60 and older.

Even though the study does have some positive news, La Crosse County Health officials say there is always room for improvement. "We are trying to make the healthy choice the easy choice. That's for our young children making La Crosse a healthy environment for them to grow up in and making that healthy choice the easy choice, but also for us adults that are so busy and we're struggling obviously with those obesity rates too," said La Crosse Co. Health Dept. Dietitian Jennifer Miller.

Experts don't know exactly what causes the changes in rates, but do say improvements were seen in low-income preschoolers who received meals from federal nutrition programs.
