Lose weight and live longer

Goodarz Danaei, M.D., of the Harvard School of Public Health in Boston, and colleagues analyzed 2005 data from the National Center for Health Statistics, the National Health and Nutrition Examination Survey, and the Behavioral Risk Factor Surveillance System, performing an extensive review of epidemiologic studies to estimate the effects of the risk factors on eight subgroups of the U.S. population, called the “Eight Americas.”

Overall, the researchers estimated that the risk factors reduced life expectancy at birth in 2005 by 4.9 years in men and 4.1 years in women. They found that the life expectancy effects of the risk factors were smallest in Asians (4.1 years for men and 3.6 years for women) and largest in Southern rural African-Americans (6.7 years for men and 5.7 years for women).
