Social Isolation of the Impaired Elderly in Japan

Abstract
This study reports on social isolation of the frail elderly using a representative sample of 441 persons living in downtown Tokyo. The average SII (Social Isolation Index) scores of the aged who were living with their families were 7.92 and S.D. 4.15 and those of persons who were living alone and elderly couples 9.14, 4.26, respectively. The relationships between length of residence and SII score was statistically significant at the 5% level. Analysis by stepwise regression disclosed that variables which genuinely influenced the scores of SII were: 1) whether older persons were physically and/or mentally impaired, 2) whether they had children who were living separately, 3) length of residence, 4) number of family members, and 5) amount of household income. These results indicated that socioeconomic factors had substantial impact on social isolation of the impaired elderly in Japan.
