There are few studies involving predictive models in a community context. The aim of this study was to determine the validation of a new model for predicting fall risk in older adults (65+) living alone in community dwellings (n = 186; n = 117) with a test\u2013retest reliability study. We consider in the predictive model the significant factors emerged from the bivariate analysis: age, zone, social community resources, physical exercise, self-perception of health, difficulty to keep standing, difficulty to sit and get up from a chair, strain to see, use of technical devices, hypertension and number of medications. The final model explained 28.5% of the risk of falling in older adults living alone in community dwellings. The AUC = 0.660 (se = 0.065, IC 95% 0.533\u20130.787, p = 0.017). The predictive model developed revealed a satisfactory discriminatory performance of the model and can contribute to clinical practice, with respect to the evaluation of risk of falling in this frailty group and preventing falls.<\/jats:p>","DOI":"10.3390\/ijerph20136284","type":"journal-article","created":{"date-parts":[[2023,7,4]],"date-time":"2023-07-04T01:42:47Z","timestamp":1688434967000},"page":"6284","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Older People Living Alone: A Predictive Model of Fall Risk"],"prefix":"10.3390","volume":"20","author":[{"given":"Isabel","family":"Lage","sequence":"first","affiliation":[{"name":"School of Nursing, University of Minho, 4710-057 Braga, Portugal"}]},{"given":"F\u00e1tima","family":"Braga","sequence":"additional","affiliation":[{"name":"School of Nursing, University of Minho, 4710-057 Braga, Portugal"},{"name":"Nursing Research Centre, University of Minho, 4710-057 Braga, Portugal"}]},{"given":"Manuela","family":"Almendra","sequence":"additional","affiliation":[{"name":"School of Nursing, University of Minho, 4710-057 Braga, Portugal"},{"name":"Nursing Research Centre, University of Minho, 4710-057 Braga, Portugal"}]},{"given":"Filipe","family":"Meneses","sequence":"additional","affiliation":[{"name":"School of Engineering, University of Minho, 4710-057 Braga, Portugal"},{"name":"Centro de Computa\u00e7\u00e3o Gr\u00e1fica, 4800-058 Guimar\u00e3es, Portugal"},{"name":"Algoritmi Research Centre, University of Minho, 4710-057 Braga, Portugal"}]},{"given":"Laetitia","family":"Teixeira","sequence":"additional","affiliation":[{"name":"ICBAS, University of Porto, 4050-313 Porto, Portugal"},{"name":"CINTESIS@RISE, ICBAS, University of Porto, 4050-313 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9016-9528","authenticated-orcid":false,"given":"Odete","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"School of Nursing, University of Minho, 4710-057 Braga, Portugal"},{"name":"Nursing Research Centre, University of Minho, 4710-057 Braga, Portugal"},{"name":"Health Sciences Research Unit: Nursing (UICISA:E), Nursing School of Coimbra (ESEnfC), 3045-043 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,3]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2023, June 15).
