Key result
Hypertensive disorders affect ~6% of pregnancies, rising with maternal age, BMI, and baseline blood pressure.
Why the study?
Hypertensive disorders of pregnancy are a major cause of maternal and neonatal mortality and morbidity, representing a global public health problem affecting maternal and children's health.
Observational (n=277,632)
Yes
Hypertensive disorders of pregnancy affect 6.40% of pregnant women in this large Chinese cohort, highlighting the importance of pre-pregnancy blood pressure and weight management, particularly for older women.
May warrant closer antenatal BP monitoring in higher-risk women; leaves open prospective validation and prevention trials.
As a major cause of maternal and neonatal mortality and morbidity, hypertensive disorders of pregnancy (HDP) are a global public health problem affecting maternal and children's health. The incidence of HDP was 6.40% among 277,632 pregnant women. With the progress of pregnancy, the proportion of pregnant women with high normal blood pressure (BP) and the incidence of HDP increased gradually. The incidence of HDP increased with pregnancy age, body mass index, and BP of pregnant women during first trimester. To reduce the incidence of HDP effectively, we should pay more attention to older women who plan to become pregnant, measures should be taken to control BP and weight in pre-pregnancy.

Zhao et al. (2021) conducted an observational in Hypertensive disorders of pregnancy (n=277,632). Maternal age, body mass index, and first-trimester blood pressure was evaluated on Incidence of hypertensive disorders of pregnancy (HDP). Among 277,632 pregnant women, the incidence of hypertensive disorders of pregnancy was 6.40%, which increased with maternal age, body mass index, and first-trimester blood pressure.
