Patients on CAPD started to enroll from 2014 to 2016 and ended follow-up by 2017. Frailty was assessed by clinical frailty scale (CFS), and cognitive function was assessed by Montreal Cognitive Assessment (MoCA). Totally 784 CAPD patients were recruited, with median duration of PD 30.7 (8.9~54.3) months. The mean age was 48.8\u2009\u00b1\u200914.6 years, 320 (40.8%) patients were female and 130 (16.6%) had diabetic nephropathy. Patients with cognitive impairment were more than those with frailty (55.5% vs. 27.6%). Coexisting frailty and cognitive impairment was present in 23.9% patients. Pathway analysis showed that CFS score was negatively associated with MoCA score (\u03b2\u2009=\u2009\u22120.69,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.001). Coexisting frailty and cognitive impairment was associated with decreased patient survival rate (Log-rank\u2009=\u200984.33,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.001) and increased peritonitis rate (0.22 vs. 0.11, 0.15 and 0.12 episodes per patient year, respectively; all\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.001). It was concluded that there was a relatively high prevalence of coexisting frailty and cognitive impairment among patients on CAPD. Frailty was positively associated with cognitive impairment. Coexisting frailty and cognitive impairment increased the risk of adverse outcomes.\n                  <\/jats:p>","DOI":"10.1038\/s41598-018-35548-4","type":"journal-article","created":{"date-parts":[[2018,11,19]],"date-time":"2018-11-19T09:24:34Z","timestamp":1542619474000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Prevalence and Prognosis of Coexisting Frailty and Cognitive Impairment in Patients on Continuous Ambulatory Peritoneal Dialysis"],"prefix":"10.1038","volume":"8","author":[{"given":"Chunyan","family":"Yi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianxiong","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peiyi","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuchao","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueqing","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0437-2015","authenticated-orcid":false,"given":"Xiao","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2018,11,23]]},"reference":[{"key":"35548_CR1","doi-asserted-by":"publisher","first-page":"420","DOI":"10.1053\/j.ackd.2009.07.008","volume":"16","author":"WL Cook","year":"2009","unstructured":"Cook, W.
