Breech presentation occurred in 3.8% of all single deliveries. Main determinants of breech presentation at birth were: gestational age and birth weight (the lower, the higher the incidence of breech presentation), maternal age (the older the mother, the higher the risk of breech presentation), parity (the frequency of breech decreased with increasing parity) and previous cesarean section. Breech presentation resulted more frequent after assisted reproduction procedures.<\/jats:p>","DOI":"10.1155\/2019\/9581439","type":"journal-article","created":{"date-parts":[[2019,9,16]],"date-time":"2019-09-16T19:30:59Z","timestamp":1568662259000},"page":"1-6","source":"Crossref","is-referenced-by-count":16,"title":["Preterm Birth, Low Gestational Age, Low Birth Weight, Parity, and Other Determinants of Breech Presentation: Results from a Large Retrospective Population-Based Study"],"prefix":"10.1155","volume":"2019","author":[{"given":"Stefania Antonia","family":"Noli","sequence":"first","affiliation":[{"name":"Dept of Clinical Sciences and Community Health, Universit\u00e0 degli Studi di Milano, Milan, Italy"},{"name":"IRCCS Fondazione Ca\u2019 Granda, Ospedale Maggiore Policlinico, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria","family":"Baini","sequence":"additional","affiliation":[{"name":"Dept of Clinical Sciences and Community Health, Universit\u00e0 degli Studi di Milano, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5624-4854","authenticated-orcid":true,"given":"Fabio","family":"Parazzini","sequence":"additional","affiliation":[{"name":"Dept of Clinical Sciences and Community Health, Universit\u00e0 degli Studi di Milano, Milan, Italy"},{"name":"IRCCS Fondazione Ca\u2019 Granda, Ospedale Maggiore Policlinico, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paola Agnese","family":"Mauri","sequence":"additional","affiliation":[{"name":"Dept of Clinical Sciences and Community Health, Universit\u00e0 degli Studi di Milano, Milan, Italy"},{"name":"IRCCS Fondazione Ca\u2019 Granda, Ospedale Maggiore Policlinico, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele","family":"Vignali","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology Unit, P.O.
