The purpose of this study is to elucidate the correlation between social capital and frailty of homebound community-dwelling elderly individuals without certification for long-term care. Subjects were 47 homebound and 47 age- and sex-matched, non-homebound elderly individuals evaluated from July to November, 2016. Variable parameters were physical, mental, and social frailty, Tilburg Frailty Indicator score, and social capital. The correlation between social capital and frailty in home-bounded elderlies was analyzed using the χ2 Test. Social capital was significantly correlated with mental frailty among homebound elderly individuals. In contrast, social capital was significantly correlated with all types of frailty among non-homebound elderly individuals. Among community-dwelling elderly individuals, social capital is related to prevention of comprehensive frailty and mental frailty. On the other hand, screening and intervention for prevention of long term-care are necessary for homebound elderly individuals.

This study aimed to verify whether the incidence of frailty in elderly individuals is higher among those who are housebound than those who are not. This study found no correlation between elderly people’s houseboundedeness and physical, mental, social, and overall frailty. However, the Tilburg Frailty Indicator (TFI) frailty score and grip strength value were higher in non-housebound elderly persons than in housebound elderly ones. This suggests that being housebound may lead to frailty. On the other hand, it is thought that individual interaction with family and friends, and lack of anxiety about falls correlates with the prevention of frailty in housebound elderly persons. The results of the study also suggest that the basic checklist may be effective for ascertaining the actual situation of housebound elderly people who may be manifesting frailty.
