Feature of trajectory of blood pressure among pregnant women with gestational hypertension

OBJECTIVE We aimed to describe the feature and the trajectory of blood pressure (BP) among pregnant women with onset of gestational hypertension. METHODS This epidemiology cohort study of pregnant women enrolled in Zhoushan, Zhejiang, included 4050 participants from the Zhoushan Pregnant Women Cohort. Each participant contributed up to eight serial perinatal visits of BP measurements from 2001 to 2018. Segmented mixed models were utilized to identify the dramatic change points in the relationship of BP elevation and gestational week among pregnant women with onset of gestational hypertension. RESULTS Despite of in which gestational week gestational hypertension developed, the SBP and DBP levels of pregnant women in each gestational hypertension category maintained the stable and normal levels (SBP
