Characteristics of housebound elderly by mobility level in Japan

The purpose of the present study was to describe characteristics of the housebound elderly by their mobility levels. Disabled elderly people in Japan were interviewed at home by nurses. Housebound status was defined as people who left the house less than once a week. Characteristics of housebound elderly were compared with non-housebound elderly by three mobility levels: (i) Non-walking group (n=72); 5 m-walking group (n=153); going-by-bus group (n=96). Housebound elderly were not found in the going-by-bus group. Among the elderly in the non-walking group, the cognitive function of the housebound elderly was significantly lower and the housebound elderly were less well cared for; however, their caregivers rated their caregiving burden significantly lower than did caregivers of the non-housebound elderly. Among those in the 5 m-walking group, the autonomy and social networks of the housebound elderly were significantly less than for the non-housebound. The characteristics of housebound elderly showed differences by mobility levels.
