METHODS: The population in this historical population-based cohort study was all preterm (&lt;37 weeks gestation) live-born singletons born in Iceland from January 1, 1997 to December 31, 2018 and their mothers; a total of 3837 births. Data was obtained from the Icelandic Medical Birth Registry. The group of migrant women was defined as women with other citizenship  than Icelandic. Migrant women were divided into three groups based on their country of citizenship Human Development Index (HDI). Both descriptive and analytical statistics were used in data processing.  RESULTS: The incidence of preterm births in Iceland increased during the study period (3,9% 1998-2001 vs. 4,5% 2012-2018, p&lt;0,005) and was significantly higher among migrant mothers, especially from countries with the lowest HDI (OR 1,49 (CI 1,21-1,81) p&lt;0,001) .  Infants of mothers from countries with the lowest HDI had a significantly lower prevalence of respiratory distress syndrome compared with infants of Icelandic mothers (4,5% vs. 11,4%, p=0,035) meanwhile infants of mothers from countries with a medium high HDI were more often small for gestational age compared with infants of Icelandic mothers (11,4% vs. 6,9%, p=0,021). CONCLUSION: Preterm births have become more common in Iceland and the incidence is significantly higher among migrant mothers, however the outcomes of preterm infants are generally good and mostly comparable between Icelandic and migrant mothers.<\/jats:p>","DOI":"10.17992\/lbl.2024.03.784","type":"journal-article","created":{"date-parts":[[2024,3,4]],"date-time":"2024-03-04T09:36:12Z","timestamp":1709544972000},"page":"135-143","source":"Crossref","is-referenced-by-count":1,"title":["Perinatal outcomes of preterm births occuring to native-born and migrant mothers in Iceland"],"prefix":"10.17992","volume":"110","author":[{"name":"Department of Obstetrics and Gynecology, Landsp\u00edtali \u2013 The National University Hospital of Iceland","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1sd\u00eds Bj\u00f6rk","family":"Gunnarsd\u00f3ttir","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thordur","family":"Thorkelsson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Children's Hospital , Landsp\u00edtali \u2013 The National University Hospital of Iceland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ragnheidur I","family":"Bjarnad\u00f3ttir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Obstetrics and Gynecology, Landsp\u00edtali \u2013 The National University Hospital of Iceland, Faculty of Medicine, University of Iceland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Embla Yr","family":"Gudmundsdottir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"The Reykjav\u00edk Birth Center, Faculty of Nursing and Midwifery, University of Iceland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7439","published-online":{"date-parts":[[2024,3,7]]},"container-title":["L\u00e6knabla\u00f0i\u00f0"],"original-title":["Fyrirburaf\u00e6\u00f0ingar \u00e1\u00cdslandi 1997-2018:Hefur uppruni m\u00e6\u00f0ra \u00e1hrif \u00e1 \u00fatkomur barna?"],"deposited":{"date-parts":[[2024,3,4]],"date-time":"2024-03-04T09:36:16Z","timestamp":1709544976000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.laeknabladid.is\/tolublod\/2024\/03\/nr\/8572"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,3,7]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2024,3,7]]},"published-print":{"date-parts":[[2024,3,7]]}},"URL":"https:\/\/doi.org\/10.17992\/lbl.2024.03.784","relation":{},"ISSN":["0023-7213","1670-4959"],"issn-type":[{"value":"0023-7213","type":"print"},{"value":"1670-4959","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,3,7]]}}}
