Evaluation of complex activities in daily living of elderly Japanese with visual impairment.

This study was conducted to determine whether elderly subjects with visual impairment differ in the performance of complex activities in daily living from those without visual impairment. The study subjects were residents in two homes for the aged in Japan, and consisted of 37 elderly people with visual impairment, and 42 elderly people, serving as controls; ages ranged from 64 to 95 years. Complex activities of the subjects were ascertained by interview using a 46-item questionnaire. The visually impaired elderly had lower performance levels for telephone use (p = 0.007), shopping (p = 0.049), cleaning up one's room (p = 0.001), and utilization of medical facilities (p = 0.001) in instrumental ADL (IADL); for interest in TV or radio (p = 0.004) and religious faith (p = 0.042) in "enriching activities"; and for visiting behaviors (p < 0.05) in "social role". The performances of complex activities by the elderly with visual impairment were diminished in specific categories, but not overall, and this may be attributable to poor mobility and/or more passive attitudes in their daily activities.
