AbstractIt is well known that disability rates among the American elderly have declined over the past decades.
The cause of this decline is less well established. In this paper, we test one important possible explanation--that
the decline in disability occurred because of chronic disease prevention efforts among the elderly.
For this purpose we analyze data from the National Long Term Care Survey and from the National
Health and Interview Survey. Our findings suggest that primary prevention, as reflected in decreased
disease prevalence, was not responsible for advances made in elderly functioning between 1980 and
2000. We found a broad decline in less severe forms of disability that is unlikely to have resulted
from improved disease management. Instead, these measured improvements in functioning may reflect
environmental, technological, and/or socioeconomic changes. Improvements in the more severe forms
of disability were modest and were restricted to those suffering from particular illnesses, which make
improved and/or more aggressive management a plausible explanation and one that might increase
costs should the trend persist.
