Input: The study's lead author  Zachary Ward   described the forecast as "sobering."
But   he  added  "It should not be surprising that we are heading in this direction. We are already approaching this level of adult obesity for certain subgroups [and] areas of the country."
Still   Ward  expressed some surprise at how strongly being obese at a very young age predicted obesity decades down the road.
 Ward  is a doctoral candidate in health policy with the Harvard T.H. Chan School of Public Health's Center for Health Decision Science  in Boston.
The study by  Ward  and  his  colleagues appears in the Nov. 30 issue of the New England Journal of Medicine.

More than half of U.S. children could be obese by age 35
