The primary outcome was recurrent sPTB &lt;37 weeks. Analyses stratified by gestational age of prior sPTB and adjusted for confounders using multivariable logistic regression.<\/jats:p><jats:p>\n            Results\u2003The overall sPTB rate was 33.7%, with no statistical difference between women with and without prior term births (28.9 vs. 37.7%, p\u2009=\u20090.2). Among women with prior second-trimester loss (16\u2013236\/7 weeks), those with a term birth had a decreased sPTB rate (15.4 vs. 43.2%, p\u2009=\u20090.02), which persisted after adjusting for age and 17-\u03b1 hydroxyprogesterone caproate use. For women with prior sPTB \u226524 weeks, there was no difference in sPTB with and without prior term births (29.5 vs. 26.6%, p\u2009=\u20090.7).

Women with prior preterm and term births should be counseled accordingly and all sPTB prevention strategies should be recommended.<\/jats:p>","DOI":"10.1055\/s-0037-1607317","type":"journal-article","created":{"date-parts":[[2017,10,27]],"date-time":"2017-10-27T23:31:27Z","timestamp":1509147087000},"page":"380-384","source":"Crossref","is-referenced-by-count":6,"title":["The Effect of Prior Term Birth on Risk of Recurrent Spontaneous Preterm Birth"],"prefix":"10.1055","volume":"35","author":[{"given":"Amy","family":"Turitz","sequence":"first","affiliation":[{"name":"Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, Columbia University Medical Center, New York, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michal","family":"Elovitz","sequence":"first","affiliation":[{"name":"Maternal and Child Health Research Program, Department of Obstetrics and Gynecology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Levine","sequence":"first","affiliation":[{"name":"Maternal and Child Health Research Program, Department of Obstetrics and Gynecology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie","family":"Purisch","sequence":"additional","affiliation":[{"name":"Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, Columbia University Medical Center, New York, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,10,27]]},"container-title":["American Journal of Perinatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0037-1607317.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,3,7]],"date-time":"2018-03-07T23:36:31Z","timestamp":1520465791000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0037-1607317"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,10,27]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2018,3,7]]},"published-print":{"date-parts":[[2018,3]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0037-1607317","relation":{},"ISSN":["0735-1631","1098-8785"],"issn-type":[{"value":"0735-1631","type":"print"},{"value":"1098-8785","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,10,27]]}}}
