The handgrip strength was assessed using an electronic handgrip dynamometer. The 5CST and gait speed were assessed by the trained researchers. The bioimpedance analysis device was used to evaluate the skeletal muscle index. We used the Asian Working Group for Sarcopenia diagnosis criteria as the gold standard. According to the receiver operating characteristic curve, we determine the optimal cut\u2010off value using the Youden index.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1027 participants were included in this analysis, including 337 men and 690 women with an average age of 70.35\u00a0\u00b1\u00a07.24\u00a0years. The prevalence of sarcopenia in total participants was 24.9%. The optimal cut\u2010off value of 5CST in the total population was 10.9\u00a0s. Stratified by age and gender, for the older adults aged 60\u201369\u00a0years, the optimal cut\u2010off values were 9.2\u00a0s in men and 10.8 s in women; for the older adults aged 70\u201379\u00a0years, cut\u2010off values were 10.2\u00a0s in men and 10.9\u00a0s in women; and for the older adults over 80\u00a0years, cut\u2010off values were 14.0\u00a0s in men and 11.5\u00a0s in women (all <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001). The areas under the curve of 5CST were 0.632 in men and 0.650 in women (both <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001).

The cut\u2010off determined in our study will help community workers detect more people with sarcopenia and benefit from early intervention and management of sarcopenia in practice.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcsm.13441","type":"journal-article","created":{"date-parts":[[2024,2,12]],"date-time":"2024-02-12T02:49:25Z","timestamp":1707706165000},"page":"756-764","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["The optimal cut\u2010off value of five\u2010time chair stand test for assessing sarcopenia among Chinese community\u2010dwelling older adults"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-6707-6655","authenticated-orcid":false,"given":"Yu\u2010Hua","family":"Li","sequence":"first","affiliation":[{"name":"Xiangya Nursing School The Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiu\u2010Hua","family":"Wang","sequence":"additional","affiliation":[{"name":"Xiangya Nursing School The Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shi","family":"Ya","sequence":"additional","affiliation":[{"name":"School of Health Sciences, Faculty of Biology, Medicine and Health The University of Manchester  Manchester UK"},{"name":"School of Nursing and School of Public Health Yangzhou University  Yangzhou Jiangsu China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huang","family":"Jiaoling","sequence":"additional","affiliation":[{"name":"Xiangya Nursing School The Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Hua","sequence":"additional","affiliation":[{"name":"Xiangya Nursing School The Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,2,11]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamda.2019.12.012"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afq034"},{"key":"e_1_2_8_4_1","unstructured":"RenX ZhangX HeQ DuL ChenK ChenS PanY.Prevalence of sarcopenia in Chinese community elderly: a systematic review and meta\u2010analysis.12th National Sports Science Conference.
