Richard Suzman, director of the National Institute on Aging’s Division of Behavioral and Social Research, tells the Health Blog that the findings will be used to help shape policies for preventing functional decline and disability as Americans get older.

Another federal health and retirement study has found that increasing levels of disability over 55 are linked to the rise in obesity, he notes.
Judith Kasper, principal investigator of the study at Hopkins, says the survey will collect a wide ragne of information about health, medical care and the living environment, as well as economic and emotional well-being and the ability to participate in everyday activities that people value such as preparing meals. “For individuals and their families, late-life functioning plays an important role in quality of life, and at the societal level it plays very directly into health care utilization and costs,” Kasper says. “You can’t develop sound policy without an understanding of the basic issues and what’s
