Age, self-assessed health status, and cognition

Data from a recent project involving 362 adults ranging from 20 to 79 years of age were reanalyzed to examine the effects of statistical control of self-assessed health status on the age trends in several measures of cognitive functioning. The major result was that the age trends were virtually identical with, and without, control of the health-status variable. Implications of the views that the lack of health influences was due to a narrow range of health status or to insensitive assessment of health status were discussed.
