Study group A (n\u00a0=\u00a0360) had already been taking L-thyroxine prior to conception, study group B (n\u00a0=\u00a0580) started taking it after conception. Both\n            study groups had a maximum gestational age of 12\u00a0+\u00a00 GW. In the study groups, TSH and free thyroxine levels were determined regularly for dose adjustment purposes. The aim was to keep the\n            free thyroxine level in the euthyroid hyperthyroxinemic range within the pregnancy adapted reference range. The control group (n = 500) had taken L-thyroxine during pregnancy according to\n            criteria that were not known, as the questionnaire did not include any questions regarding this matter. Taking other risk factors into account, the influence of pregnancy-adapted\n            L-thyroxine replacement therapy on the rate of premature births was determined using logistic regression analysis.<\/jats:p><jats:p>Compared with the control group, the premature birth rate was 70% lower (p\u00a0&lt;\u00a00.0001) in study group A and 42% lower in study group B (p\u00a0=\u00a00.0086), while the odds ratio, at 3.46, was\n            particularly significant in study group A. High blood pressure (odds ratio 5.21), body mass index per kg\/m2 (odds ratio 0.91) and S. p. premature birth were identified as other\n            independent risk factors.<\/jats:p><jats:p>The results show an association between more intensive thyroid diagnostics and pregnancy-adapted L-thyroxine replacement therapy and a decrease in premature births. Further studies should\n            be conducted to confirm these results.<\/jats:p>","DOI":"10.1055\/a-2103-8143","type":"journal-article","created":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T05:48:40Z","timestamp":1696571320000},"page":"1361-1370","source":"Crossref","is-referenced-by-count":0,"title":["Reducing the Rate of Premature Births through Early Diagnosis and Pregnancy-Adapted Treatment of Hypothyroidism"],"prefix":"10.1055","volume":"83","author":[{"given":"Pompilio","family":"Torremante","sequence":"additional","affiliation":[{"name":"Frauenarzt\/Spezielle Geburtshilfe und Perinatalmedizin, Ochsenhausen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nils Kristian","family":"Berge","sequence":"additional","affiliation":[{"name":"Abteilung f\u00fcr Medizinische Statistik, Biomathematik und Informationsverarbeitung, Universit\u00e4tsmedizin Mannheim, Ruprecht-Karls-Universit\u00e4t Heidelberg Medizinische\n          Fakult\u00e4t Mannheim, Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christel","family":"Weiss","sequence":"additional","affiliation":[{"name":"Abteilung f\u00fcr Medizinische Statistik, Biomathematik und Informationsverarbeitung, Universit\u00e4tsmedizin Mannheim, Ruprecht-Karls-Universit\u00e4t Heidelberg Medizinische\n          Fakult\u00e4t Mannheim, Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,10,5]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"235","DOI":"10.1055\/s-0030-1247486","article-title":"Fr\u00fchgeburtlichkeit","volume":"4","author":"H Stepan","year":"2010","journal-title":"Frauenheilkunde up2date"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"95","DOI":"10.2478\/jbcr-2018-0013","article-title":"Prevention of Preterm Birth","volume":"11","author":"ID Ivanov","year":"2018","journal-title":"J Biomed Clin Res"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"227","DOI":"10.3238\/arztebl.2013.0227","article-title":"The prevention, diagnosis and treatment of premature labor","volume":"110","author":"E Schleussner","year":"2013","journal-title":"Dtsch Arztebl Int"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"547","DOI":"10.1055\/a-2044-0203","article-title":"Prevention and Therapy of Preterm Birth.
