Method: Street connectivity and street density, markers for neighborhood walkability, were assessed through linkage to secondary data sources. Physical performance was measured with timed-walk and chair-stand tests assessed during follow-up visits about every 2 years for 12 to 14 years. Multilevel models predicted change in physical performance, controlling for age, number of incident comorbidities, self-rated health, and death during follow-up. Results: Overall, physical performance declined during follow-up ( p &lt; .001). Neighborhood walkability had no effect on change in physical performance among women who reported not walking at baseline. However, among women who walked, greater neighborhood walkability was associated with a slower decline in dynamic leg strength, indicated by score on chair stand. Discussion: Neighborhood walkability may protect against decline in physical performance.<\/jats:p>","DOI":"10.1177\/0898264311412597","type":"journal-article","created":{"date-parts":[[2011,7,4]],"date-time":"2011-07-04T07:11:08Z","timestamp":1309763468000},"page":"1246-1262","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":26,"title":["Built Environment and Lower Extremity Physical Performance"],"prefix":"10.1177","volume":"23","author":[{"given":"Yvonne L.","family":"Michael","sequence":"first","affiliation":[{"name":"Drexel University School of Public Health, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Gold","sequence":"additional","affiliation":[{"name":"Center for Health Research, Portland, OR, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nancy A.","family":"Perrin","sequence":"additional","affiliation":[{"name":"Center for Health Research, Portland, OR, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa A.","family":"Hillier","sequence":"additional","affiliation":[{"name":"Center for Health Research, Portland, OR, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,7,1]]},"reference":[{"key":"bibr1-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1093\/geronb\/gbn018"},{"key":"bibr2-0898264311412597","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2006.085837"},{"key":"bibr3-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1186\/1476-072X-9-20"},{"key":"bibr4-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2007.03.009"},{"key":"bibr5-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1289\/ehp.11160"},{"key":"bibr6-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1016\/S1361-9209(97)00009-6"},{"key":"bibr7-0898264311412597","first-page":"206","volume-title":"The Portland edge: Challenges and successes in growing communities","author":"Chapman N.","year":"2004"},{"key":"bibr8-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwn185"},{"key":"bibr9-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2009.06.041"},{"key":"bibr10-0898264311412597","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2004.054494"},{"key":"bibr11-0898264311412597","doi-asserted-by":"publisher","DOI":"10.4278\/0890-1171-18.6.435"},{"key":"bibr12-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2006.00700.x"},{"key":"bibr13-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1016\/S1047-2797(01)00221-6"},{"key":"bibr14-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2004.52174.x"},{"key":"bibr15-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1123\/japa.12.1.45"},{"key":"bibr16-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2007.11.042"},{"key":"bibr17-0898264311412597","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2008.01.013"},{"issue":"1","key":"bibr18-0898264311412597","first-page":"M43","volume":"55","author":"Fried L.
