Chinese older pregnant women with the HDPs had high pooled incidences of abnormal body mass index, maternal education, family history of hypertension, history of chronic hypertension, gestational diabetes, irregular delivery inspection, psychosocial factors, and primiparity compared to those without HDPs. The incidence of cesarean delivery, placental abruption, premature rupture of membranes, postpartum hemorrhage, preterm birth, fetal asphyxia, fetal distress, fetal growth restriction, and low birth weight in Chinese older pregnant women with HPDs were significantly higher than those without HDPs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study identified several possible risk factors which promoted the onset of HDPs in Chinese older pregnant women, and HDPs significantly increases risk of adverse pregnancy outcomes (APOs). Further research is needed to take targeted measures to prevent HDPs and explore efficient management methods to minimize the risk of APOs associated with HDPs in Chinese older pregnant women.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jog.15295","type":"journal-article","created":{"date-parts":[[2022,5,21]],"date-time":"2022-05-21T07:20:46Z","timestamp":1653117646000},"page":"1710-1720","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Risk
