Method: Cross-sectional logistic regression analyses among women aged 74 to 86 years (Finnish Twin Study on Aging, third wave, n = 302). Results: Thirty-one participants reported unmet physical activity need. Short sleepers had fivefold and long sleepers threefold odds for unmet physical activity need compared with normative sleepers, while for daytime tiredness the odds were double. Presence of daytime tiredness and unmet physical activity coincided with higher prevalence of chronic diseases, depressive symptoms and walking difficulties, which partly explains the observed associations. Poor sleep quality was not associated with unmet physical activity need. Discussion: Older women with nonoptimal sleep characteristics who perceive unmet physical activity need may benefit from solutions that improve their perceived opportunities for physical activity.<\/jats:p>","DOI":"10.1177\/0898264318814021","type":"journal-article","created":{"date-parts":[[2018,11,23]],"date-time":"2018-11-23T04:44:08Z","timestamp":1542948248000},"page":"199-207","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["The Relationship Between Sleep Characteristics and Unmet Physical Activity Need in Older Women"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5108-9330","authenticated-orcid":false,"given":"Lotta","family":"Palmberg","sequence":"first","affiliation":[{"name":"Gerontology Research Center, Faculty of Sport and Health Sciences, University of Jyv\u00e4skyl\u00e4, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"Viljanen","sequence":"additional","affiliation":[{"name":"Gerontology Research Center, Faculty of Sport and Health Sciences, University of Jyv\u00e4skyl\u00e4, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1604-1945","authenticated-orcid":false,"given":"Taina","family":"Rantanen","sequence":"additional","affiliation":[{"name":"Gerontology Research Center, Faculty of Sport and Health Sciences, University of Jyv\u00e4skyl\u00e4, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaakko","family":"Kaprio","sequence":"additional","affiliation":[{"name":"Institute for Molecular Medicine Finland, Helsinki, Finland"},{"name":"Department of Public Health, University of Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merja","family":"Rantakokko","sequence":"additional","affiliation":[{"name":"Gerontology Research Center, Faculty of Sport and Health Sciences, University of Jyv\u00e4skyl\u00e4, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,11,23]]},"reference":[{"key":"bibr1-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1111\/jsr.12407"},{"key":"bibr2-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1177\/2055217316682774"},{"key":"bibr3-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1093\/geronb\/gbu124"},{"key":"bibr4-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1016\/j.sleep.2009.07.004"},{"key":"bibr5-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1375\/twin.4.6.464"},{"key":"bibr6-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1007\/BF03324782"},{"key":"bibr7-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-4356(02)00463-8"},{"key":"bibr8-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2004.52529_2.x"},{"key":"bibr9-0898264318814021","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2003.035576"},{"key":"bibr10-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/62.2.191"},{"key":"bibr11-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1016\/0165-1781(89)90047-4"},{"key":"bibr12-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehr007"},{"key":"bibr13-0898264318814021","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/33.5.585"},{"key":"bibr14-0898264318814021","doi-asserted-by":"publisher","DOI":"10.2337\/dc09-1124"},{"key":"bibr15-0898264318814021","first-page":"126","volume":"100","author":"Caspersen C.
