Studies: Myriad factors push obesity rates higher
Too much junk food, TV and a lack of physical-education classes or other exercise make it difficult for U.S. youth to stay at a healthy weight and likely contribute to skyrocketing rates of childhood obesity, according to studies published in a special supplement of the American Journal of Preventive Medicine (Oct, 2007), 33(4), A1-A6, 269-358. Minorities and children in poor neighborhoods are particularly vulnerable, the studies found.

Bryn Austin, an assistant Harvard School of Public Health professor.
