Abstract

Objectives

To evaluate the physical strength, cerebral function, and mental health conditions in elderly persons, and to examine the correlation between these functions.

Methods

The subjects were 151 independent-living elderly Japanese women, mean age 70 +/-5 years (+/-SD; range, 60 to 80 years), with normal abilities in daily life. The health check-up was conducted from April to May 1997. Physical strength was estimated by measuring seven activities. Cerebral functions were assessed by six sub-tests of the General Aptitude Test Battery (GATB). Their mental health status was measured by four sub-scales of the General Health Questionnaire (GHQ)-28.

Results

The physical strenght and almost all of the cerebral functions decreased with age. Social dysfunction and severe depression on the GHQ sub-scales also worsened with age. Physical strength was strongly correlated with cerebral functions after adjusting for the confounding effect of aging. There were also interrelations between physical strength and mental health.

Conclusions

This study provided important information on the correlation between physical and mental status in elderly women. Future longitudinal studies with the intervention of physical training are required to determine whether a causal relationship exists between these factors.
