Elevated Pre-Pregnancy Blood Pressure and the Risk of Adverse Pregnancy Outcomes: Evidence From a Nationwide Population-Based Study.

ABSTRACT:

Background

Pre-pregnancy blood pressure (BP) has gained attention as a potential predictor of adverse pregnancy outcomes. However, data on the impact of mildly elevated BP, particularly in women without overt hypertension, remain limited. In this study, we aimed to examine the association between pre-pregnancy BP and adverse pregnancy outcomes in women without a history of hypertension.

Methods

In this retrospective nationwide study, we included pregnant women with pre-pregnancy BP below 140/90 mmHg and no prior diagnosis of hypertension. Participants were categorized based on their pre-pregnancy BP into the normal BP (< 120/80 mmHg), elevated BP (120-129 and < 80 mmHg), and stage 1 hypertension (130-139 or 80-89 mmHg) groups. The following adverse pregnancy outcomes were re
