"We were focusing mostly on cheerful BMI - over 25 - and the end was to throw light on the relationships between weight and longevity rather than expect to find anything completely new," said Berrington de Gonzalez, an investigator with the National Cancer Institute's unit of cancer epidemiology and genetics in Bethesda, Md.

Although her set did not calculate the number of life years potentially damned due to obesity, they determined the highest death rates for this group were from cardiovascular disease. About 58 percent of read participants were female, and the median baseline age was 58.
