The older people experience significant reductions in muscle mass and physical performance. Cross\u2010sectional studies have found an association between the sarcopenia and sleep duration. Due to lack of evidence of longitude study, it is necessary to investigate the association between sarcopenia and sleep duration in the older people.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study utilized longitudinal data including 2061 older people from China Health and Retirement Longitudinal Study 2011\u20132020. Diagnosis was made based on the Asian Working Group for Sarcopenia criteria 2019. There were 246 participants with sarcopenia, 628 participants with possible sarcopenia and 1187 participants with nonsarcopenia. Kaplan\u2013Meier curve, log\u2010rank test and Cox proportional risk model were used to explore the relationship between sarcopenia exposure and clinical outcome of abnormal sleep duration. Three models adjusting for different factors were built, and hazard ratios (HRs) were calculated. Restricted cubic spline analyses explored the exposure\u2013response relationship between sarcopenia components and abnormal sleep duration incidence, while receiver operating characteristic curve was used to assess their predictive power.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The incidences of short or long, decreased sleep duration of the sarcopenia and possible sarcopenia groups in the overall population were significantly higher than those of the nonsarcopenia group (respectively, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Sarcopenia (HR\u2009=\u20091.240, 95% CI [confidence interval]: 1.023\u20131.417) was significantly associated with an increased risk of abnormal sleep duration by Cox model analysis with adjusting factors. Results of analyses stratified by sleep duration showed that sarcopenia (HR\u2009=\u20091.566, 95% CI: 1.192\u20132.057) and possible sarcopenia (HR\u2009=\u20091.286, 95% CI: 1.054\u20131.570) were positively associated with long sleep duration.

The proportion of the condition of change in sleep duration from normal to &lt;\u20096\u2009h or &gt;\u20098\u2009h in the sarcopenia and possible sarcopenia groups was significantly different from the nonsarcopenia group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results suggest that sarcopenia and possible sarcopenia are associated with abnormal sleep duration and the decrease of ASM and handgrip strength, and the increase of the five\u2010time chair stand test is positively related to abnormal sleep duration, which implies that delaying the development of sarcopenia could be a new pathway to improve sleep health in older people.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcsm.70017","type":"journal-article","created":{"date-parts":[[2025,7,26]],"date-time":"2025-07-26T12:00:32Z","timestamp":1753531232000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Sarcopenia Is Associated With Increased Risk of Abnormal Sleep Duration in the Older People: A 10\u2010Year Cohort Study From China"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-6267-9097","authenticated-orcid":false,"given":"Yimi","family":"Wang","sequence":"first","affiliation":[{"name":"School of Medicine Shihezi University  Shihezi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weixin","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Medicine Shihezi University  Shihezi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Medicine Shihezi University  Shihezi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingzhi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Medicine Shihezi University  Shihezi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bingqing","family":"Bi","sequence":"additional","affiliation":[{"name":"School of Public Health Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9835-4012","authenticated-orcid":false,"given":"Shugang","family":"Li","sequence":"additional","affiliation":[{"name":"School of General Practice and Continuing Education Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"School of General Practice and Continuing Education Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,26]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"World Population Prospects(2024).Department of Economic and Socia Affairs Unite Nation.
