The objective of this study was to detect the prevalence and risk factors of preterm birth among Icelandic and migrant women in Iceland. MATERIAL AND METHODS: The study was a population-based cohort study with data from the Icelandic Medical Birth Register. The cohort included all women who had a singleton birth from 22w0d to 36w6d  of pregnancy in the years 1997-2018, a total of 89 170 women. The group was divided in two; women with an Icelandic citizenship and women with foreign citizenship, that were further divided according to the Human Development Index (HDI) of their country of citizenship. Preterm birth rate and risk factor prevalence was analysed according to this classification and significance in differences measured with a chi-square test.   RESULTS: Significance in differences of preterm birth was found between Icelandic (4.4%) and migrant women (5.6%) (p&lt;0.001). Migrant women from middle-HDI countries gave birth preterm in 5.5% of cases (p&lt;0.01) and women from low-HDI countries in 6.4% of cases (p&lt;0.001). Migrant women were more often diagnosed with urinary tract infections, diabetes, intrauterine growth restriction and premature rupture of membranes, but less often with pre-eclampsia, obesity, placental defect, mental health issues and age &lt;18 years (p&lt;0.05). CONCLUSION: Migrant women in Iceland from middle-HDI and low-HDI countries give birth preterm more often than Icelandic women. A difference in risk factors is also present and needs further research. The findings can be used in continuing development of prenatal care for migrant women in Iceland.<\/jats:p>","DOI":"10.17992\/lbl.2023.02.729","type":"journal-article","created":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T14:34:47Z","timestamp":1675434887000},"page":"75-81","source":"Crossref","is-referenced-by-count":1,"title":["Preterm birth among Icelandic and migrant women in Iceland during 1997-2018 and main contributing factors"],"prefix":"10.17992","volume":"109","author":[{"name":"Department of Midwifery, Faculty of Nursing and Midwifery, University of Iceland, The Reykjav\u00edk Birth Center, Iceland","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Embla \u00ddr","family":"Gu\u00f0mundsd\u00f3ttiur","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilja","family":"Vigf\u00fasd\u00f3ttir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"The Health Directorate of East Iceland, Iceland","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helga","family":"Gottfre\u00f0sd\u00f3ttir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Midwifery, Faculty of Nursing and Midwifery, University of Iceland, Department of Obstetrics and Gynecology, Women\u00b4s Clinic, Landsp\u00edtali University Hospital, Iceland","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7439","published-online":{"date-parts":[[2023,2,6]]},"container-title":["L\u00e6knabla\u00f0i\u00f0"],"original-title":["T\u00ed\u00f0ni fyrirburaf\u00e6\u00f0inga og \u00e1h\u00e6ttu\u00fe\u00e1tta hj\u00e1 \u00edslenskum konum og konum af erlendum uppruna \u00e1 \u00e1runum 1997-2018"],"deposited":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T14:34:52Z","timestamp":1675434892000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.laeknabladid.is\/tolublod\/2023\/02\/nr\/8225"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,2,6]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2023,2,6]]},"published-print":{"date-parts":[[2023,2,6]]}},"URL":"https:\/\/doi.org\/10.17992\/lbl.2023.02.729","relation":{},"ISSN":["0023-7213","1670-4959"],"issn-type":[{"value":"0023-7213","type":"print"},{"value":"1670-4959","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,2,6]]}}}
