A PILOT STUDY OF THE SARC-F SCALE ON SCREENING SARCOPENIA AND PHYSICAL DISABILITY IN THE CHINESE OLDER PEOPLE

Introduction: The SARC-F scale is a newly developed tool to diagnose sarcopenia and obviate the need for measurement of muscle mass. SARC-F >= 4 is defined as sarcopenia. The questions of SARC-F cover physical functions targeting sarcopenia or initial presentation for sarcopenia. The aim of the study is to explore the application of SARC-F in the Chinese people. Methods: Two hundred thirty Chinese people over 65 years old were assessed by the SARC-F scale, PSMS, Lawton IADL and the shortened version of the falls efficacy scale-international( the short FES-I). Hospitalization was investigated. Physical performance and strength were measured. The association of SARC-F with other scales or tests was analyzed. Results: Poor physical performance and grip strength were associated with SARC-F >= 4 independently (P<0.005). The x value for agreement of SARC-F >= 4 and cutoff points of tests were 0.391 to 0.635. The short FES-I were correlated to SARC-F scores (Spearman's coefficient 0.692). Poor PSMS and Lawton IADL scores were associated with SARC-F >= 4(P=0.000) and SARC-F >= 4 was associated with hospitalization in the past 2 years (P=0.000). Conclusion: The SARC-F scale can identify old Chinese people with impaired physical function who may suffered from sarcopenia. SARC-F judgment reflects fear of falling, indicates the hospitalization events and is associated with ability of daily life. Thus, SARC-F may be a simple and useful tool for screening individuals with impaired physical function. Further studies on SARC-F in Chinese people would be worthy.
