The measurements could also be used for comparison in other areas and for reasearch. At the Reginonal Archives of Skagafjordur, rare data about the physique of children in Saudarkrokur in 1912\u20131953, measured by Jon Th. Bjornsson, is preserved. MATERIAL AND METHODS: Height, weight, grip strenght, thorax expansion and tidal volume were measured twice in 2018\u20132019 on 7\u201315-year-old children in elementary schools in Saudarkrokur and Varmahlid. These measurements were compared with similar measurements from 1912\u20131953. RESULTS: Children in 2018\u20132019 at ages 7\u201315 years were significantly taller, heavier, with greater thorax expansion and tidal volume than their peers in 1912\u20131953 (p&lt;0,001\u20130,037). Children in 2018\u20132019 at ages 7\u201314 years had significantly higher body mass index than their peers in 1912\u20131953 (p&lt;0,001\u20130,027). If adjusted for height and weight in thorax expansion and tidal volume measurements, similar results were found. Children in 2018\u20132019 had significantly less grip strength than their peers in 1912\u20131953 at ages 7 and 9\u201312-years when adjusted for height and weight (p&lt;0,001\u20130,025). There was significant development in the physique of children over the years 1912\u20131953 in most measurements and age groups (p&lt;0,001\u20130,040). CONCLUSIONS: A significant increase in measured factors in 2018\u20132019 compared to 1912\u20131953 can possibly be attributed to improved quality of life.<\/jats:p>","DOI":"10.17992\/lbl.2022.06.694","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T14:26:31Z","timestamp":1654007191000},"page":"279-286","source":"Crossref","is-referenced-by-count":0,"title":["Physique of children and adolescents in Northern Iceland then and now"],"prefix":"10.17992","volume":"108","author":[{"name":"Research Centre of Movement Science, Department of Physiotherapy, School of Health Sciences, University of Iceland, The Health Care Institution of North Iceland in Sau\u00f0\u00e1rkr\u00f3kur","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda Bj\u00f6rk","family":"Valbj\u00f6rnsd\u00f3ttir","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00de\u00f3rarinn","family":"Sveinsson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Research Centre of Movement Science, Department of Physiotherapy, School of Health Sciences, University of Iceland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1rni","family":"\u00c1rnason","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Research Centre of Movement Science, Department of Physiotherapy, School of Health Sciences, University of Iceland, G\u00e1ski Physiotherapy, Reykjav\u00edk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7439","published-online":{"date-parts":[[2022,6,2]]},"container-title":["L\u00e6knabla\u00f0i\u00f0"],"original-title":["L\u00edkams\u00e1stand barna og unglinga \u00e1 Sau\u00f0\u00e1rkr\u00f3ki og \u00ed Varmahl\u00ed\u00f0 fyrr og n\u00fa"],"deposited":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T14:26:35Z","timestamp":1654007195000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.laeknabladid.is\/tolublod\/2022\/06\/nr\/8052"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,2]]},"references-count":0,"journal-issue":{"issue":"06","published-online":{"date-parts":[[2022,6,2]]},"published-print":{"date-parts":[[2022,6,2]]}},"URL":"https:\/\/doi.org\/10.17992\/lbl.2022.06.694","relation":{},"ISSN":["0023-7213","1670-4959"],"issn-type":[{"type":"print","value":"0023-7213"},{"type":"electronic","value":"1670-4959"}],"subject":[],"published":{"date-parts":[[2022,6,2]]}}}
