Clinical features and antenatal risk factors for postpartum-onset hypertensive disorders

ABSTRACTObjective: To identify the clinical features and risk factors for diagnosis of a postpartum-onset hypertensive disorder. Methods: A retrospective cohort study of singleton pregnancies. Clinical features of postpartum-onset hypertensive disorders were evaluated, and prenatal risk factors were also identified with a multivariate logistic regression model. Results: Of 1,964 women, 57 (2.9%) developed hypertensive disorder after delivery. The independent risk factors were assisted reproductive technology, pre-pregnancy body mass index, chronic nephritis, hypothyroidism, high-normal blood pressure before or at delivery, and cesarean section. Conclusion: Careful monitoring of blood pressure should be considered for women with the identified risk factors even after delivery.
