In 2014, 1,725 participants (aged 65\u201374) were assessed. With a retention rate of 81%, in 2016, 1,409 individuals were reassessed. Risk factors for FOF were entered into the CaRT: age, sex, education, self-rated health, comorbidity, medication, visual impairment, frailty, cognitive deficit, depression, fall history, Short Physical Performance Battery (SPPB), walking aid use, and mobility disability measured by the Nagi questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The classification tree included 12 end groups representing differential risks of FOF with a minimum of two and a maximum of five predictors. The first split in the tree involved impaired physical function (SPPB scores). Respondents with less than 8 in SPPB score and mobility disability had 82% risk of developing FOF at the end of 2-year follow-up. Between 23.2% and 82.3% of the risk of developing FOF in 2 years of follow-up were explained by only five variables: age, sex, self-rated health, functional impairment measured by SPPB, and mobility disability. In those with no functional impairment or mobility disability, levels of education, sex, and self-rated health were important predictors of FOF in the future.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This classification tree included different groups based on specific combinations of a maximum of five easily measurable predictors with emphasis on impaired physical functioning risk factors for developing FOF.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/gerona\/glz002","type":"journal-article","created":{"date-parts":[[2019,2,8]],"date-time":"2019-02-08T19:41:42Z","timestamp":1549654902000},"page":"181-188","source":"Crossref","is-referenced-by-count":37,"title":["A Regression Tree for Identifying Risk Factors for Fear of Falling: The International Mobility in Aging Study (IMIAS)"],"prefix":"10.1093","volume":"75","author":[{"given":"Carmen-Lucia","family":"Curcio","sequence":"first","affiliation":[{"name":"Research Group on Geriatrics and Gerontology, Faculty of Health Sciences, Universidad de Caldas, Manizales, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1553-1392","authenticated-orcid":false,"given":"Yan Yan","family":"Wu","sequence":"first","affiliation":[{"name":"Office of Public Health Studies, University of Hawaii at Manoa, Honolulu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Afshin","family":"Vafaei","sequence":"first","affiliation":[{"name":"Department of Health Sciences, Lakehead University, Thunder Bay, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana Fernandez de Souza","family":"Barbosa","sequence":"first","affiliation":[{"name":"Department of Physiotherapy, Universidade Federal do Rio Grande do Norte, Natal, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Guerra","sequence":"first","affiliation":[{"name":"Department of Physiotherapy, Universidade Federal do Rio Grande do Norte, Natal, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack","family":"Guralnik","sequence":"first","affiliation":[{"name":"Department of Epidemiology and Public Health, School of Medicine, University of Maryland, Baltimore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4360-8174","authenticated-orcid":false,"given":"Fernando","family":"Gomez","sequence":"first","affiliation":[{"name":"Research Group on Geriatrics and Gerontology, Faculty of Health Sciences, Universidad de Caldas, Manizales, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,2,8]]},"reference":[{"key":"2020042210554187200_CIT0001","doi-asserted-by":"publisher","first-page":"751","DOI":"10.1080\/09638280500304794","article-title":"The risk of being fearful or fearless of falls in older people: an empirical validation","volume":"28","author":"Delbaere","year":"2006","journal-title":"Disabil Rehabil."},{"key":"2020042210554187200_CIT0002","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1093\/geronj\/48.Special_Issue.35","article-title":"Fear of falling and low self-efficacy: a case of dependence in elderly persons","volume":"48(spec no)","author":"Tinetti","year":"1993","journal-title":"J Gerontol"},{"key":"2020042210554187200_CIT0003","doi-asserted-by":"crossref","first-page":"1329","DOI":"10.1046\/j.1532-5415.2002.50352.x","article-title":"Falls and fear of falling: which comes first?
