No matter what the reasons, more public health initiatives are needed to curb the obesity epidemic, Dr. Thomas Frieden, director of the CDC, said during the telebriefing.
"There has been progress in some initiatives," Frieden said. "But there's not yet been an example of statewide change to reduce the prevalence of obesity."
Frieden called for more state initiatives such as programs to increase physical activity, breastfeeding, increase fruit and vegetable intake, while reducing high-calorie food intake and time spent in front of television and computer screens.
The BRFSS data were limited because state health department surveyors can only reach households that have a landline telephone.
