The relationship between frailty and motor function among living in the community elderly females.

[Purpose] This study aimed to investigate the prevalence of frailty among community-dwelling elderly females, and to examine its relation to motor function and the main risk factors of frailty. [Participants and Methods] The participants were 67 community-dwelling elderly females, aged 76.2 ± 7.7 years. We performed measurements of physical parameters, motor functions (such as grip strength), timed up and go test (TUG), walking speed, and frailty (measured using the Kihon Checklist [KCL]). [Results] KCL scores were 31.3%, 31.3%, and 37.3% in the frailty, pre-frailty, and robust groups, respectively. The frailty group was older than the pre-frailty and robust groups. Additionally, the different groups showed significant differences in grip strength, TUG, and walking speed. The highest median KCL score was for depression, followed by physical function. As a results, frailty was evident even among health-conscious elderly people. [Conclusion] It is essential to identify frailty at an early stage and identify its preventive factors, in order to extend the healthy life expectancy of the local population.
