Abstract:Objective To identify a sarcopenia screening tool for community-dwelling older adults, and to provide evidence for early detection and intervention. Methods A total of 1 455 older adults were selected from urban communities of 13 counties in Lvliang City of Shanxi Province and were screened for sarcopenia by utilizing the SARC-F, SARC-CalF and SARC-F+EBM. The sensitivity, specificity,positive predictive value (PPV),negative predictive value (NPV) and the area under the receiver operating characteristic (ROC) curve (AUC) of SARC-F,SARC-CalF and SARC-F+EBM were calculated by using the Asian Working Group for Sarcopenia (AWGS) 2019 consensus as the "gold standard". Results The prevalence of sarcopenia was 18.69% in community-dwelling older adults according to the AWGS 2019 criteria. The sensitivity of SARC-F, SARC-CalF and SARC-F+EBM was 21.32%, 66.67% and 43.75% respectively. The specificity was 86.19%, 92.73% and 87.24% respectively. The PPV was 25.89%, 66.70% and 44.07% respectively. The NPV was 82.62%, 91.65% and 87.09% respectively. The AUC was 0.665,0.755 and 0.752, respectively. Conclusion The SARC-CalF and SARC-F+EBM were more accurate for screening sarcopenia compared with the SARC-F,which can be used as rapid sarcopenia screening tools for community-dwelling older adults in China.
