The number of low-income pre-schoolers classified as obese is down.
According to a new report from the Centers for Disease Control and Prevention, the numbers have modestly dropped over the last decade.
"The declines we're presenting here are pretty modest, but it is a change in direction," study author Dr. Heidi M. Blanck told The New York Times. "We were going up before. And this data shows we're going down. For us, that's pretty exciting."
Low-income children are at higher risk of becoming obese because healthy food is often limited in poorer neighborhoods.
Experts say two possible contributors to the lower number are an increase in breastfeeding and more awareness of the importance of physical activity.
The study was published Tuesday in The Journal of the American Medical Association.
