  B. Low-Income Kids at High Risk for Childhood Obesity

Narrator: This is Science Today. Childhood obesity is a problem for all Americans, but it's hitting children living in low-income neighborhoods harder. Patricia Crawford, co-director of the Center for Weight and Health at the University of California, Berkeley, explains.

Crawford: We are seeing that the rates for overweight are increasing faster now for children at low income. And that is very clearly linked I think to the opportunities that these children have to get more exercise to and to get more healthy foods…

Narrator: With limited healthy choices nearby, Crawford says children of low-income families consume more fast food because it's convenient and cheaper.

Crawford: The obesity promoting foods are more likely to be eaten by those at low income. You can get more calories for your money with these foods that are of lower nutritional quality. And in addition the environment in which they live, is such that it is harder to walk in neighborhoods and there are fewer neighborhood resources to promote physical activity.

Narrator: For Science Today, I'm Larissa Branin.
