Screening practices frequently rely on Unplanned Weight Loss (UPWL), potentially overlooking at-risk individuals. This study aims to assess the prevalence of nutritional risk, identified by UPWL and sarcopenia, across different body mass index categories in a nursing home (NH) population. Methods: Cross-sectional data were collected from an NH in a Danish municipality, including those of all self-reliant participants who consented and excluding those of terminally ill older adults. Data on age, sex, height, weight, and chronic diseases were extracted from medical records. Nutritional risk was assessed using two markers: a UPWL of \u22651 kg during the last six months and muscle strength via a modified 30 s chair stand test as a marker of sarcopenia. An ANOVA and Fisher\u2019s Exact Test were used to assess differences, followed by a post hoc Tukey test. Results: In our study of older adults (n = 93, mean age 83.2 \u00b1 9.12 years, 63% female), 17 individuals (19%) had UPWL, and 27 (29%) had sarcopenia. Among those with obesity, twelve (48%) had sarcopenia, but only two (8%) had UPWL. In contrast, seven (21%) of those with normal weight had sarcopenia, while eleven (33%) experienced UPWL. Conclusions: Older adults in NHs are at nutritional risk, but the prevalence varies significantly depending on whether UPWL or sarcopenia markers are applied for categorization. Sarcopenia prevalence was the highest in the obesity group, suggesting a need for integrating muscle strength or quantity assessments into community care to identify older adults at nutritional risk better.<\/jats:p>","DOI":"10.3390\/nu17010171","type":"journal-article","created":{"date-parts":[[2025,1,2]],"date-time":"2025-01-02T06:05:10Z","timestamp":1735797910000},"page":"171","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Unplanned Weight Loss and Sarcopenia Across Body Mass Index Categories in Nursing Homes\u2014A Cross-Sectional Study"],"prefix":"10.3390","volume":"17","author":[{"given":"Laura","family":"Klaassen","sequence":"first","affiliation":[{"name":"LUMC Center of Medicine for Older People, Leiden University, 2333 ZA Leiden, The Netherlands"},{"name":"Department of Nutrition, Exercise and Sports, Faculty of Science, University of Copenhagen, 1870 Frederiksberg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6472-8226","authenticated-orcid":false,"given":"Tenna","family":"Christoffersen","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Exercise and Sports, Faculty of Science, University of Copenhagen, 1870 Frederiksberg, Denmark"},{"name":"Nutrition and Health, University College Absalon, 4200 Slagelse, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9281-9915","authenticated-orcid":false,"given":"Margit Dall","family":"Aaslyng","sequence":"additional","affiliation":[{"name":"Nutrition and Health, University College Absalon, 4200 Slagelse, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2495-2511","authenticated-orcid":false,"given":"Inge","family":"Tetens","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Exercise and Sports, Faculty of Science, University of Copenhagen, 1870 Frederiksberg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1016\/j.clnu.2016.09.004","article-title":"ESPEN guidelines on definitions and terminology of clinical nutrition","volume":"36","author":"Cederholm","year":"2017","journal-title":"Clin.
