A questionnaire survey and accelerometer measurements collected data from 79 participants aged \u2265\u200965\u2009years on Kabashima and Hisakajima Islands in May\u2013June 2024. The median daily step count was 4555, similar to or higher than national averages. Significant associations were found between physical activity levels and age, living alone, car ownership, frequency of going out, and self\u2010rated health. The smallest community had the highest median step count. There was substantial day\u2010to\u2010day variation in individual activity levels. Despite lacking environmental factors that earlier studies have identified as promoting physical activity, the residents' activity levels were higher than mainland averages, suggesting that relationships between neighborhood environment and physical activity are dependent on the context of populations. Possible explanations for the physical activity of our study participants include health\u2010conscious behaviors of older islanders, unique environmental factors on small islands promoting activity, self\u2010selection to live in an environment that requires physical activity, selection bias toward more active individuals, or the possibility that only those who are able to maintain island residence currently live there. Further longer\u2010term research should examine intra\u2010individual variation and elucidate factors influencing physical activity on small remote islands.<\/jats:p>","DOI":"10.1002\/ajhb.70089","type":"journal-article","created":{"date-parts":[[2025,6,13]],"date-time":"2025-06-13T01:32:24Z","timestamp":1749778344000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Physical Activity Levels Among Elderly Residents in Small Remote Islands in Japan"],"prefix":"10.1002","volume":"37","author":[{"given":"Satoko","family":"Kosaka","sequence":"first","affiliation":[{"name":"Nagasaki University Graduate School of Biomedical Sciences  Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayumi","family":"Ohnishi","sequence":"additional","affiliation":[{"name":"Nagasaki University Graduate School of Biomedical Sciences  Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryoko","family":"Kawasaki","sequence":"additional","affiliation":[{"name":"Nagasaki University Graduate School of Biomedical Sciences  Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Umezaki","sequence":"additional","affiliation":[{"name":"Graduate School of Medicine, The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rieko","family":"Nakao","sequence":"additional","affiliation":[{"name":"Nagasaki University Graduate School of Biomedical Sciences  Nagasaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,6,12]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/17437199.2020.1760728"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amepre.2011.06.036"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-3797(01)00426-3"},{"key":"e_1_2_9_5_1","unstructured":"Ministry of Health Labor and Welfare.2024.\u201cNational Health and Nutrition Survey.\u201dhttps:\/\/www.mhlw.go.jp\/toukei\/itiran\/gaiyo\/k\u2010eisei.html."},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0007114510005441"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(15)01284-2"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-019-6424-y"},{"key":"e_1_2_9_9_1","unstructured":"Statistics bureau of Japan.2021.\u201c2020 Population Census.\u201dhttps:\/\/www.stat.go.jp\/data\/kokusei\/2020\/kekka.html."},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005768-200212000-00020"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurpub\/ckv131"}],"container-title":["American Journal of Human Biology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajhb.70089","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,19]],"date-time":"2025-07-19T13:23:35Z","timestamp":1752931415000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajhb.70089"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6]]},"references-count":10,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2025,6]]}},"alternative-id":["10.1002\/ajhb.70089"],"URL":"https:\/\/doi.org\/10.1002\/ajhb.70089","archive":["Portico"],"relation":{},"ISSN":["1042-0533","1520-6300"],"issn-type":[{"value":"1042-0533","type":"print"},{"value":"1520-6300","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,6]]},"assertion":[{"value":"2025-04-05","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-06-02","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-06-12","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70089"}}
