[A comparative study of the characteristics and social backgrounds of frail and elderly persons at home, long-stay elderly hospital patients, and residents of welfare homes for the frail elderly].

: Three studies were carried out in Mino City, Osaka Prefecture, on 188 frail and elderly persons living at home (the home group), 61 elderly patients who had been hospitalized more than six months (the inpatient group), and 72 residents of welfare homes for the frail elderly (the resident group). The characteristics and social backgrounds of the three groups were compared. About 30% of each group had suffered a stroke. As for ADL score, moderate disability was dominant in the home group, severe disability in the inpatient group, and slight disability in the resident group. The proportions of those who had been living alone and those who had no spouse were significantly higher in the inpatient group and in the resident group than in the home group. Significantly fewer subjects in the resident group had been living with their offspring than in the home group or in the inpatient group. The percentage of those who did not have their own home was the highest for the resident group. Multivariate analyses using Hayashi's quantification method II were conducted for a comparison between cases belonging to the home group and the inpatient group, and between the home group and the resident group. The analysis of the home group and the inpatient group revealed a relationship of the inpatient group to severe disability in ADL, and living alone. Differences between these two groups were related to such variables as ADL, sex, living or not living alone, living or not living with offspring, and having or not having a spouse.(ABSTRACT TRUNCATED AT 250 WORDS)
