    Abstract:
    There is insufficient epidemiological data about frail elders in Japan. Few studies concerning the relationship between psychosocial characteristics and frailty exist in the literature. The purpose of this study was to assess the prevalence and to explore the characteristics of the frail elderly in a community of Japan by cross-sectional and case-control studies. Data were collected from a total of 2,310 non-institutionalized persons aged 65 years or older, by mail survey and interview. We defined frailty as a precursor of disability. The prevalence of frail elders was estimated at 6.1%. After controlling for age and gender, multiple logistic regression analyses disclosed that frail elders displayed significantly higher emotional reliance on another person, worsening self-efficacy, fair or poor subjective health, and poor functional ability than independent elders, and significantly higher self-efficacy than bedridden elders. The most noticeable finding in this study was the significant association of psychosocial factors with frailty among the community-dwelling elderly. Based on our study results, we suggest that when controlling physical variables, psychosocial variables might strongly affect the frail status among elderly persons.
