Using data from the longitudinal Health and Retirement Study (biennial interviews from 1998 to 2018), we analyzed perceived social support measured preinjury and functional status [activities of daily living (ADL) or instrumental activities of daily living (IADL) limitations] measured at pre- and postinjury interviews. Among 709 respondents, 61% anticipated social support from friends or family if they required future assistance with personal care, 16% had difficulty with ADL preinjury, and 9% had difficulty with IADL preinjury. Among 1697 postinjury follow-up interviews (mean follow-up time: 2.8 years), ADL limitations and IADL limitations were reported in 752 and 683 interviews, respectively. During follow-up, any preinjury IADL limitations were associated with more postinjury IADL limitations among people without social support [adjusted incidence rate ratio (aIRR): 2.505, 95% confidence interval (CI): 1.765\u20133.555] but not among people with preinjury perceived social support (aIRR: 1.355, 95% CI: 0.950\u20131.940, interaction <jats:italic toggle=\"yes\">P<\/jats:italic>\u2005=\u20050.016). Any preinjury ADL limitations were associated with more postinjury ADL limitations among people with (aIRR: 1.471, 95% CI: 1.124\u20131.925) or without (aIRR: 2.084, 95% CI: 1.563\u20132.778) preinjury perceived social support. Preinjury perceived social support moderates the association between pre- and postinjury functional status in older adults experiencing a hip fracture. Older adults experiencing pre-existing IADL limitations without social support are at high risk for continued or increased activity limitations.<\/jats:p>","DOI":"10.1097\/mrr.0000000000000662","type":"journal-article","created":{"date-parts":[[2025,2,26]],"date-time":"2025-02-26T17:00:48Z","timestamp":1740589248000},"page":"100-105","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Preinjury functional status is associated with functional status after hip fracture in older adults without preinjury perceived social support"],"prefix":"10.1097","volume":"48","author":[{"given":"Yan","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Sociology, East Carolina University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isaac","family":"Kolam","sequence":"additional","affiliation":[{"name":"Brody School of Medicine at East Carolina University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitry","family":"Tumin","sequence":"additional","affiliation":[{"name":"Department of Academic Affairs, Brody School of Medicine at East Carolina University, Greenville, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,4,28]]},"reference":[{"key":"R1-20250506","doi-asserted-by":"crossref","first-page":"874","DOI":"10.1016\/j.apmr.2018.10.008","article-title":"Residual disability, mortality, and nursing home placement after hip fracture over 2 decades.","volume":"100","author":"Abraham","year":"2019","journal-title":"Arch Phys Med Rehabil"},{"key":"R2-20250506","doi-asserted-by":"crossref","first-page":"58","DOI":"10.1080\/17453674.2019.1680485","article-title":"Postoperative mortality after a hip fracture over a 15-year period in Denmark: a national register study.","volume":"91","author":"Gundel","year":"2020","journal-title":"Acta Orthop"},{"key":"R3-20250506","doi-asserted-by":"crossref","first-page":"1225","DOI":"10.1001\/jamainternmed.2020.2975","article-title":"Incidence of hip fracture over 4 decades in the Framingham heart study.","volume":"180","author":"Swayambunathan","year":"2020","journal-title":"JAMA Intern Med"},{"key":"R4-20250506","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1016\/j.physio.2020.02.001","article-title":"Patients\u2019 perceptions of rehabilitation in the community following hip fracture surgery.
