This study investigated the risk factors for placental abruption and developed a predictive model using the Synthetic Minority Over-sampling Technique (SMOTE). A total of 280 pregnant women with preeclampsia treated between September 2020 and September 2025 were enrolled and classified into placental abruption and non-placental abruption groups. Logistic regression showed that parity \u22653, severe preeclampsia, anemia, polyhydramnios, and short umbilical cord were independent risk factors for placental abruption. ROC analysis demonstrated that the SMOTE-based model had better predictive performance than the original model, with a higher AUC (0.863, 95% CI: 0.817\u20130.901 vs 0.792, 95% CI: 0.739\u20130.838; z=2.163, P=0.031). The SMOTE-based model also showed higher F-score and positive predictive value, although its true positive rate was lower than that of the original model. These findings indicate that a SMOTE-based predictive model may provide useful support for early risk assessment and prevention of placental abruption in women with preeclampsia.<\/jats:p>","DOI":"10.29063\/ajrh2026\/v30i14.4","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T11:35:03Z","timestamp":1785843303000},"page":"26-34","source":"Crossref","is-referenced-by-count":0,"title":["Development and validation of a predictive risk model for placental abruption in women with pre-eclampsia using SMOTE"],"prefix":"10.29063","volume":"30","author":[{"given":"Fangfang","family":"Wei","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijuan","family":"Rong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"11599","published-online":{"date-parts":[[2026,7,31]]},"container-title":["African Journal of Reproductive Health"],"original-title":[],"deposited":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T11:35:05Z","timestamp":1785843305000},"score":1,"resource":{"primary":{"URL":"https:\/\/ajrh.org\/index.php\/ajrh\/article\/view\/7184"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,31]]},"references-count":0,"journal-issue":{"issue":"14","published-online":{"date-parts":[[2026,7,31]]},"published-print":{"date-parts":[[2026,7,31]]}},"URL":"https:\/\/doi.org\/10.29063\/ajrh2026\/v30i14.4","relation":{},"ISSN":["1118-4841","1118-4841"],"issn-type":[{"value":"1118-4841","type":"print"},{"value":"1118-4841","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,31]]}}}
