Widely reported figures from the Centers for Disease Control and Prevention last year showing that obesity was close to surpassing smoking as the No. 1 cause of death in the U.S. were incorrect, the agency says. A computer error is blamed for the report showing 400,000 obesity-related deaths between 1990 and 2000—an increase of 100,000. The correct figures show a more modest increase of about 65,000 deaths.
