Placenta previa increases the risks of obstetrical complications. Many studies have reported a link between various ABO blood types and pregnancy complications. This study is aimed at describing and comparing the characteristics and outcomes of women with placenta previa by ABO blood type. Methods. Data for this study was obtained from a retrospective cohort study between January 1, 2014, and June 30, 2019, of all clinically confirmed placenta previa in a university-based tertiary medical center. Both types of A, B, O, AB, and combining O and non-O blood types were compared to the characteristics and outcomes. Results. 1678 participants with placenta previa were included in this study. The highest participants were blood type O with 666 (39.7%), followed by type A with 508 (30.3%) and type B with 395 (23.5%), and the lowest participants were AB with 109 (6.5%). Blood type AB had a higher incidence of antepartum hemorrhage (<jats:inline-formula><a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><a:mi>p<\/a:mi><a:mo>=<\/a:mo><a:mn>0.017<\/a:mn><\/a:math><\/jats:inline-formula>), predelivery anemia (<jats:inline-formula><c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><c:mi>p<\/c:mi><c:mo>=<\/c:mo><c:mn>0.036<\/c:mn><\/c:math><\/jats:inline-formula>), and preterm birth (<jats:inline-formula><e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><e:mi>p<\/e:mi><e:mo>=<\/e:mo><e:mn>0.015<\/e:mn><\/e:math><\/jats:inline-formula>) in placenta previa women.

Conclusion. Type AB blood may be a potential risk factor for women with placenta previa. This finding may help provide any obstetrician to predict the risk of complication for placenta previa women by the ABO blood types.<\/jats:p>","DOI":"10.1155\/2023\/4725064","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T16:35:10Z","timestamp":1674664510000},"page":"1-8","source":"Crossref","is-referenced-by-count":6,"title":["Blood Type and Outcomes in Pregnant Women with Placenta Previa"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2773-9166","authenticated-orcid":true,"given":"Dazhi","family":"Fan","sequence":"first","affiliation":[{"name":"Foshan Institute of Fetal Medicine, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"},{"name":"Department of Obstetrics, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2017-5353","authenticated-orcid":true,"given":"Jiaming","family":"Rao","sequence":"additional","affiliation":[{"name":"Foshan Institute of Fetal Medicine, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5324-9959","authenticated-orcid":true,"given":"Huishan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Foshan Institute of Fetal Medicine, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5423-0619","authenticated-orcid":true,"given":"Dongxin","family":"Lin","sequence":"additional","affiliation":[{"name":"Foshan Institute of Fetal Medicine, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8547-4285","authenticated-orcid":true,"given":"Xiaoling","family":"Guo","sequence":"additional","affiliation":[{"name":"Foshan Institute of Fetal Medicine, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"},{"name":"Department of Obstetrics, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4964-0258","authenticated-orcid":true,"given":"Zhengping","family":"Liu","sequence":"additional","affiliation":[{"name":"Foshan Institute of Fetal Medicine, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"},{"name":"Department of Obstetrics, Affiliated Foshan Maternity & Child Healthcare Hospital, Southern Medical University, Foshan, Guangdong 528000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0000000000001005"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-020-05912-9"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.2147\/TCRM.S288461"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000005107"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1111\/1471-0528.15306"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1186\/s12884-021-03923-1"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1038\/srep40320"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0170194"},{"key":"9","article-title":"Maternal and neonatal outcomes of repeated antepartum bleeding in 493 placenta previa cases: a retrospective study","volume":"1-6","author":"S.
