 The purpose of this presentation is to analyze the risk factors and cut-off point of a short battery of physical performance tests for identifying community-dwelling elderly people with pre-frailty.


 A short battery of physical performance tests was employed at community activity center to assess the following characteristics among elderly people: balance, mobility, and flexibility. Instructions were provided to participants by demonstration.


 Logistic regression analysis indicated that four indicators were significantly correlated to pre-frailty, that is, pre-frailty included falls in the previous year (OR = 3.05, 95% CI of OR = 1.46 – 6.38), smoking (OR = 3.22, 95% CI of OR = 1.40 – 7.38), hypertension (OR = 2.21, 95% CI of OR = 1.16 – 4.21) and bone and joint disease (OR = 8.96, 95% CI of OR = 3.05 – 26.30) (Tables 3). Furthermore, according to the logistic regression analysis results, three of the mentioned tests could significantly predict pre-frailty, namely, right-hand grip (OR = 0.96, 95% CI of OR = 1.92 – 1.99), left-hand grip (OR = 0.92, 95% CI of OR = 1.87 – 1.97), and the 8-foot up-and-go test (OR = 1.15, 95% CI of OR = 1.04 – 1.27). The results indicate that grip and 8-foot up-and-go are effective independent predictors for


To the best of our knowledge, this study is the first academic examination of the cut-off points for objective physiological indicators assessing pre-frailty among elderly Asian people. Although this study focuses on community-dwelling elderly people in East Asian countries, research investigating the diagnosis methods, sensitivity, specificity, NPV, and PPV of screening methods for pre-frailty are scarce. Furthermore, in this study, pre-frailty is determined according to an established and validated index
