Pregnancy adverse outcomes associated with change of blood pressure categories in early pregnancy among women with normotension: a retrospective cohort study.

Researchers in China studied how changes in blood pressure during early pregnancy affect outcomes for mothers and babies. They followed nearly 74,000 pregnant women with normal blood pressure before pregnancy, measuring their blood pressure twice before 20 weeks of gestation. The women were grouped into three categories based on American heart health guidelines: normal blood pressure, elevated blood pressure, and stage 1 hypertension. The study found that about 13% of women saw their blood pressure worsen between the first and second measurements, while 12% improved. Women whose blood pressure increased from normal to stage 1 hypertension faced significantly higher risks of developing gestational hypertension (3.2 times higher), preeclampsia (1.9 times higher), gestational diabetes (1.8 times higher), and postpartum hypertension (1.6 times higher) compared to women who maintained normal blood pressure. Conversely, women whose blood pressure improved showed decreased risks for these complications. The findings suggest that early pregnancy blood pressure changes can predict later pregnancy complications. For women experiencing rising blood pressure in early pregnancy, integrative approaches including acupuncture may be worth discussing with healthcare providers as part of a comprehensive prenatal care plan, as acupuncture has been studied for supporting healthy blood pressure regulation and stress reduction during pregnancy. When considering acupuncture during pregnancy, it's essential to work with a licensed acupuncturist who has specialized training and experience in prenatal care.

This retrospective cohort study analyzed 73,823 normotensive pregnant women in Zhoushan, China (2002-2022) to assess adverse outcomes associated with blood pressure category changes before 20 weeks gestation using ACC/AHA criteria. At initial visit, 6.68% had elevated BP and 12.15% had stage 1 hypertension. Blood pressure status worsened in 12.88% and improved in 12.08% at the second visit. Women progressing from normal BP to stage 1 hypertension showed significantly increased risks: gestational hypertension (OR=3.21, 95% CI: 2.79-3.68), preeclampsia (OR=1.88, 95% CI: 1.30-2.72), gestational diabetes (OR=1.76, 95% CI: 1.59-1.95), and postpartum hypertension (OR=1.62, 95% CI: 1.36-1.92). Conversely, BP improvement correlated with stepwise risk reduction. Similar associations were observed with adverse neonatal outcomes. Clinical takeaway: Early pregnancy BP trajectory serves as a significant predictor of maternal-fetal complications, suggesting potential benefit from early interventions including acupuncture for blood pressure management in at-risk patients.
