- The study analyzed data from 281,224 pregnant women in China to investigate the link between dynamic blood pressure trajectories during pregnancy and adverse birth outcomes.
- Three distinct systolic and diastolic blood pressure patterns were identified: Low-stable, Fast-increasing, and High-stable.
- Women with Fast-increasing or High-stable systolic trajectories had significantly higher risks of preterm birth and low birth weight compared to the Low-stable group.
- For diastolic pressure, the Fast-increasing trajectory showed the strongest associations, including a 19% higher preterm birth risk and 63% increased low birth weight risk.
- Each 10 mmHg rise in blood pressure from mid-to-late pregnancy was independently associated with increased risks of preterm birth and low birth weight.
- The findings emphasize the importance of continuous blood pressure monitoring during pregnancy for early risk identification and intervention.
