[Functional changes in one-year and related factors among community-dwelling frail elderly].
OBJECTIVE
The purpose of this study was to investigate physical and psychosocial characteristics together with life activities related to functional changes among frail elderly, including J-rank individuals able to walk outdoors and take a bus as well as people of A-rank capable of moving around inside the house but incapable of going outside.


METHODS
The study design was of longitudinal type. Participants were community-dwelling frail elderly, 61 J-rank and 90 A-rank individuals aged over 65-years and caregivers. Nurses conducted home interviews as Wajima City, Ishikawa Prefecture in Japan, in 1998 at the baseline and 1999 at follow-up, and evaluated the degree of independence of the frail elderly. With the baseline survey, physical function, psychosocial characteristics, and life activities were assessed.


RESULTS
At the follow-up survey, 3.3% people of J-rank elderly had died and 83.6% were at home. Among the A-rank elderly, 11.1% had died and 80.6% were at home. Functional change in one-year was as follows: 31.4% people of J-rank had declined and 68.6% remained the same. 19.4% people of A-rank improved, 65.3% unchanged, and 15.3% declined. Among J-rank elderly, functional decline was significantly related to low ADL level and less verbal contact with their caregivers. Life activities such as getting out to the garden or around the house, worshipping at a temple, doing house chores, shopping, and gardening, related to maintained function. Among A-rank elderly with the low ADL, function similarity declined. Life activities such as visiting friends, gardening, and performing self-care chores were significantly linked to improvement.


CONCLUSIONS
The results suggest that the degree of independence of frail elderly may easily change. ADL is related to functional change among frail elderly of both A and J rank. It is recommended that facilitating activities like house chores or getting out the house for J-rank individuals and self-care for A-rank elderly is important to prevent functional decline. Preventive community-based care for frail elderly should therefore be directed of supporting their active life.
