This study aims to explore loneliness and its associated factors, highlighting the role of specialized nursing in promoting health and quality of life for institutionalized older adults\u2019 individuals.\nMethod\nThis exploratory study, conducted between November 2020 and July 2021, collected quantitative data from 157 elderly ERPI residents (aged\u2009\u2265\u200965 years) using intentional non-probabilistic sampling. The UCLA-Loneliness Scale assessed loneliness, and a sociodemographic and clinical questionnaire characterized the sample. Data were analyzed using SPSS version 24.0, with descriptive statistics, Kolmogorov-Smirnov and Shapiro-Wilk tests for normality, and inferential tests (Mann-Whitney U, chi-square, Fisher\u2019s exact) to explore variable relationships.\nResults\nThe sample (65.6% female, mean age 84.6 years) showed a high prevalence of negative loneliness feelings (UCLA mean score 35.5, cutoff\u2009&gt;\u200932), particularly among those aged\u2009\u2265\u200985, widowed individuals, and those with multimorbidity (67.5%). A significant association was found between loneliness and multimorbidity (p\u2009=\u20090.016), but not with sociodemographic variables. Women and older participants exhibited higher dependency and loneliness scores.\nConclusion\nLoneliness is prevalent among ERPI residents, with multimorbidity as a key predictor. Specialized nursing is pivotal in implementing holistic, evidence-based interventions to mitigate loneliness, promote self-care, and enhance well-being.<\/p>","DOI":"10.21203\/rs.3.rs-7998362\/v1","type":"posted-content","created":{"date-parts":[[2025,11,6]],"date-time":"2025-11-06T16:53:39Z","timestamp":1762448019000},"source":"Crossref","is-referenced-by-count":1,"title":["Loneliness among older adults living in nursing homes in Portugal: a cross-sectional study"],"prefix":"10.21203","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4356-6613","authenticated-orcid":false,"given":"Sandra","family":"Gomes","sequence":"first","affiliation":[{"name":"Universidade de \u00c9vora, Comprehensive Health Research Centre (CHRC), Escola Superior de Enfermagem S\u00e3o Jo\u00e3o de Deus, Departamento de Enfermagem, \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5729-3334","authenticated-orcid":false,"given":"Patricia","family":"Bal\u00e3o","sequence":"additional","affiliation":[{"name":"Universidade de \u00c9vora, Comprehensive Health Research Centre (CHRC), Escola Superior de Enfermagem S\u00e3o Jo\u00e3o de Deus, Departamento de Enfermagem, \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3511-3342","authenticated-orcid":false,"given":"Maria","family":"Gomes","sequence":"additional","affiliation":[{"name":"Fondation Echaud, Sui\u00e7a"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7873-5558","authenticated-orcid":false,"given":"Cl\u00e1udia","family":"Mendes","sequence":"additional","affiliation":[{"name":"Universidade de \u00c9vora, Comprehensive Health Research Centre (CHRC), Escola Superior de Enfermagem S\u00e3o Jo\u00e3o de Deus, Departamento de Enfermagem, \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2658-3550","authenticated-orcid":false,"given":"Maria","family":"Marques","sequence":"additional","affiliation":[{"name":"Universidade de \u00c9vora, Comprehensive Health Research Centre (CHRC), Escola Superior de Enfermagem S\u00e3o Jo\u00e3o de Deus, Departamento de Enfermagem, \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1079-9624","authenticated-orcid":false,"given":"Ana","family":"Subtil","sequence":"additional","affiliation":[{"name":"NOVA National School of Public Health, Comprehensive Health Research Center (CHRC), NOVA University Lisbon, Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1174-0744","authenticated-orcid":false,"given":"Lara","family":"Pinho","sequence":"additional","affiliation":[{"name":"Instituto Polit\u00e9cnico de Viana do Castelo, Viana do Castelo, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7554-8041","authenticated-orcid":false,"given":"Manuel","family":"Lopes","sequence":"additional","affiliation":[{"name":"Universidade de \u00c9vora, Comprehensive Health Research Centre (CHRC), Escola Superior de Enfermagem S\u00e3o Jo\u00e3o de Deus, Departamento de Enfermagem, \u00c9vora, Portugal"}]}],"member":"297","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-7998362\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-7998362\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,6]],"date-time":"2025-11-06T16:53:39Z","timestamp":1762448019000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-7998362\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,6]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-7998362\/v1","relation":{},"subject":[],"published":{"date-parts":[[2025,11,6]]},"subtype":"preprint"}}
