A Centers for Disease Control and Prevention spokeswoman said the number of deaths linked to obesity isn't as high as claimed in a CDC study published in the Journal of the American Medical Association in March. The spokeswoman said the agency is conducting an internal investigation into the errors and when it completes the investigation will run an erratum in JAMA. The study showed that obesity was gaining on tobacco as the leading cause of preventable deaths in the U.S. and said about 400,000 deaths in 2000 could be linked to poor diet and lack of physical activity. The spokeswoman said the number of deaths cited was too high because of mathematical errors, but she said she did not know how great a difference would be found. The CDC began reexamining the study after independent scientists questioned some computations, she said. -- by Joseph Mantone
