CPC researchers find that higher fast food prices lead to lower weight and diabetes risk

Mar 10, 2010

A new study shows both weight and diabetes risk fell for people in communities where fast food prices increased. "This study gives us strong scientific evidence that price policies, including taxes, could actually be effective at helping control obesity and the resulting chronic diseases, like diabetes," senior author Barry M. Popkin said.

The study was published in the Archives of Internal Medicine and used data from the Coronary Artery Risk Development in Young Adults (CARDIA) study. Co-authors include Kiyah Duffey, a graduate research assistant at CPC, and CPC faculty fellows Penny Gordon-Larsen and David K. Guilkey.
