Nevertheless, this condition is overlooked in clinical practice. This study aimed to explore the factors associated with sarcopenia among older patients hospitalized for hip fracture, to identify a predictive model of sarcopenia based on variables related to this condition, and to evaluate the performance of screening tools in order to choose the most suitable to be adopted in routine care of older people with hip fracture. A cross-sectional study was undertaken with 90 patients (mean age 83.4 \u00b1 7.2 years), by assessing sociodemographic and clinical characteristics, anthropometric measures, such as body mass index (BMI) and calf circumference (CC), the functional status (Barthel Index), the nutritional status (MNA-SF), and the adherence to the Mediterranean Diet (MEDAS). Diagnosis of sarcopenia was established according to the criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). The analysis of variables associated with sarcopenia was performed using multivariate logistic regression models. Clusters of sarcopenia were explored with heatmaps and predictive risk models were estimated. Sarcopenia was confirmed in 30% of hip fracture patients. Variables with the strongest association with sarcopenia were BMI (OR = 0.79 [0.68\u20130.91], p &lt; 0.05) and CC (OR = 0.64 [0.51\u20130.81], p &lt; 0.01). CC showed a relatively high predictive capacity of sarcopenia (area under the curve: AUC = 0.82). Furthermore, CC could be a valuable tool to predict sarcopenia risk compared with the currently used screening tools, SARC-F and SARC-CalF (AUC, 0.819 vs. 0.734 and 0.576, respectively). More studies are needed to validate these findings in external study populations.<\/jats:p>","DOI":"10.3390\/nu14204255","type":"journal-article","created":{"date-parts":[[2022,10,12]],"date-time":"2022-10-12T22:45:29Z","timestamp":1665614729000},"page":"4255","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Calf Circumference, a Valuable Tool to Predict Sarcopenia in Older People Hospitalized with Hip Fracture"],"prefix":"10.3390","volume":"14","author":[{"given":"Keith","family":"Borges","sequence":"first","affiliation":[{"name":"Department of Nutrition and Food Science, Faculty of Pharmacy, University of Granada, 18071 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6405-9480","authenticated-orcid":false,"given":"Reyes","family":"Artacho","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Science, Faculty of Pharmacy, University of Granada, 18071 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosa","family":"Jodar-Graus","sequence":"additional","affiliation":[{"name":"Hospital of Neurotraumatology and Rehabilitation, 18013 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0428-2426","authenticated-orcid":false,"given":"Esther","family":"Molina-Montes","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Science, Faculty of Pharmacy, University of Granada, 18071 Granada, Spain"},{"name":"Biomedical Research Center, Institute of Nutrition and Food Technology \u201cJos\u00e9 Mataix\u201d, University of Granada, 18071 Granada, Spain"},{"name":"CIBER Epidemiolog\u00eda y Salud P\u00fablica, CIBERESP, 28029 Madrid, Spain"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria ibs.GRANADA, 18012 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8523-0689","authenticated-orcid":false,"given":"Mar\u00eda Dolores","family":"Ruiz-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Science, Faculty of Pharmacy, University of Granada, 18071 Granada, Spain"},{"name":"Biomedical Research Center, Institute of Nutrition and Food Technology \u201cJos\u00e9 Mataix\u201d, University of Granada, 18071 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1093\/ageing\/afy169","article-title":"Sarcopenia: Revised European consensus on definition and diagnosis","volume":"48","author":"Bahat","year":"2019","journal-title":"Age Ageing"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"485","DOI":"10.1002\/jcsm.12411","article-title":"Sarcopenia and its association with falls and fractures in older adults: A systematic review and meta-analysis","volume":"10","author":"Yeung","year":"2019","journal-title":"J.
