This retrospective cohort study was based on singletons who were delivered after 32 + 0 weeks between July 2015 and July 2020. We only included cases with at least two antepartum sonographies available within 4 weeks of delivery (n = 2790). We divided the study population into two groups according to the presence or absence of placental abruption and compared the clinical variables. The incidence of placental abruption was 2.0% (56\/2790) and was associated with an older maternal age, a higher rate of preeclampsia, and being small for the gestational age. A difference of &gt;2 weeks in gestational age according to BPD and AC occurred at a higher rate in the placental abruption group compared to the no abruption group (&gt;2 weeks, 21.4% (12\/56) vs. 7.5% (205\/2734), p &lt; 0.001; &gt;3 weeks, 12.5% (7\/56) vs. 2.0% (56\/2734), p &lt; 0.001). Logistic regression analysis revealed that the differences of &gt;2 weeks and &gt;3 weeks were both independent risk factors for placental abruption (odds ratio (OR) (95% confidence interval), 2.289 (1.140\u20134.600) and 3.918 (1.517\u20139.771), respectively) after adjusting for maternal age, preeclampsia, and small for gestational age births. We identified that a difference in gestational age of &gt;2 weeks between BPD and AC could be an independent predictor of placental abruption.<\/jats:p>","DOI":"10.3390\/jcm10112413","type":"journal-article","created":{"date-parts":[[2021,5,31]],"date-time":"2021-05-31T01:51:37Z","timestamp":1622425897000},"page":"2413","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Can a Difference in Gestational Age According to Biparietal Diameter and Abdominal Circumference Predict Intrapartum Placental Abruption?"],"prefix":"10.3390","volume":"10","author":[{"given":"Jee-Youn","family":"Hong","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Ha","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seo-yeon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul 03181, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji-Hee","family":"Sung","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8946-4789","authenticated-orcid":false,"given":"Suk-Joo","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3002-0048","authenticated-orcid":false,"given":"Soo-young","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheong-Rae","family":"Roh","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"332","DOI":"10.1093\/aje\/153.4.332","article-title":"Placental abruption and perinatal mortality in the United States","volume":"153","author":"Ananth","year":"2001","journal-title":"Am.
