A new study has yielded a radically different picture of aging in America, finding that how old you are plays little or no role in determining differences in health and well-being.
The researchers say the results suggest the medical community is focusing on the wrong set of factors to determine risk of dying. Rather than rely on a checklist of infirmities—heart disease, cancer, diabetes, high blood pressure, and cholesterol levels—perhaps it’s time to consider a new “comprehensive model” that looks at factors such as psychological well-being, sensory function, and mobility.
“The new comprehensive model of health identifies constellations of health completely hidden by the medical model and reclassifies about half of the people seen as healthy as having significant vulnerabilities that affect the chances that they may die or become incapacitated within five years,” says Professor Martha McClintock, a biopsychologist and lead author of the study in the Proceedings of the National Academy of Sciences.
