Abstract:
The impact of hypertensive disorders of pregnancy(HDP)on maternal and fetal outcomes is well-established.However,the relationship between high-normal blood pressure(BP)and HDP,as well as its association with adverse maternal-fetal outcomes,remains unclear.This retrospective study analyzed singleton pregnancies delivered at Obstetrics and Gynecology Hospital,Fudan University from Jan 2021 to Dec 2021.Participants were categorized into a normal BP group(BP<130/80 mmHg before delivery admission)and two high-normal BP groups(BP:130-139/80-89 mmHg)with subgroup analysis based on gestational week of BP elevation before and after 20 weeks.Maternal characteristics,HDP incidence and adverse outcomes were compared across groups.The results demonstrated that compared with the normal BP group,both high-normal BP groups showed significantly increased HDP incidence,with more pronounced risk in the high-normal BP(after 20 weeks)group.The high-normal BP(before 20 weeks)group was associated with elevated risks of iatrogenic preterm birth and small for gestational age(SGA).This study provides a theoretical basis for implementing stricter BP monitoring strategies to reduce adverse maternal and neonatal outcomes.
