Method: Health care utilization (number of emergency department [ED] visits and hospitalizations) was self-reported during monthly interviews among 419 community-dwelling African American and non-Hispanic White adults aged 75 years and older in The University of Alabama at Birmingham (UAB) Study of Aging II. Life-space was measured using the UAB Life-Space Assessment. Generalized estimating equations were used to examine associations of life-space at the beginning of each interval with health care utilization over the 1-month interval. Results: Overall, 400 participants were followed for 36 months. A 10-point decrease in life-space was associated with 14% increased odds of an ED visit and\/or hospitalization over the next month, adjusting for demographics, transportation difficulty, comorbidity, and having a doctor visit in the last month. Discussion: Life-space is a practical alternative in predicting future health care utilization to performance-based measures, which can be difficult to incorporate into clinical or public health practice.<\/jats:p>","DOI":"10.1177\/0898264317730487","type":"journal-article","created":{"date-parts":[[2017,9,14]],"date-time":"2017-09-14T07:45:56Z","timestamp":1505375156000},"page":"280-292","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":37,"title":["Life-Space Predicts Health Care Utilization in Community-Dwelling Older Adults"],"prefix":"10.1177","volume":"31","author":[{"given":"Richard E.","family":"Kennedy","sequence":"first","affiliation":[{"name":"The University of Alabama at Birmingham, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Courtney P.","family":"Williams","sequence":"additional","affiliation":[{"name":"The University of Alabama at Birmingham, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia","family":"Sawyer","sequence":"additional","affiliation":[{"name":"The University of Alabama at Birmingham, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander X.","family":"Lo","sequence":"additional","affiliation":[{"name":"The University of Alabama at Birmingham, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kay","family":"Connelly","sequence":"additional","affiliation":[{"name":"Indiana University Bloomington, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariann","family":"Nassel","sequence":"additional","affiliation":[{"name":"The University of Alabama at Birmingham, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cynthia J.","family":"Brown","sequence":"additional","affiliation":[{"name":"The University of Alabama at Birmingham, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,9,14]]},"reference":[{"key":"bibr1-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1300\/J018v22n03_07"},{"key":"bibr2-0898264317730487","volume-title":"Health status of rural Alabamians","author":"Alabama Rural Health Association","year":"1998"},{"key":"bibr3-0898264317730487","doi-asserted-by":"publisher","DOI":"10.2217\/1745509x.2.3.417"},{"key":"bibr4-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1046\/j.1532-5415.2003.51512.x"},{"key":"bibr5-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1007\/S11136-012-0315-3"},{"key":"bibr6-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1053\/J.Ajkd.2013.07.022"},{"key":"bibr7-0898264317730487","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-150-6-200903170-00005"},{"key":"bibr8-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1001\/Jama.2010.1970"},{"key":"bibr9-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1111\/J.1532-5415.2005.53501.X"},{"key":"bibr10-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9681(87)90171-8"},{"key":"bibr11-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/63.11.1241"},{"key":"bibr12-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3956(75)90026-6"},{"key":"bibr13-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1001\/Jama.2015.8035"},{"key":"bibr14-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1093\/biomet\/73.1.13"},{"key":"bibr15-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1093\/Gerona\/Glv076"},{"key":"bibr16-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1016\/J.Jclinepi.2004.06.011"},{"key":"bibr17-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1093\/ptj\/85.10.1008"},{"key":"bibr18-0898264317730487","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511763151.014"},{"key":"bibr19-0898264317730487","unstructured":"Sawyer Baker P., Allman R.
