For the first time since childhood obesity was called "epidemic," a study shows it's declining among very young children. A paper in today's edition of the Journal of the American Medical Association reports that obesity has dropped from 14% to 8% among children between the ages of two and five. It's the work of a researcher at the Centers for Disease Control. Zach Goldfarb, staff writer for the Washington Post, has more on the results as well as some theories about why that's happening.
