By Dr. Priyom Bose, Ph.D.Jun 20 2023Reviewed by Benedette Cuffari, M.Sc. Gestational hypertension has been recognized as one of the leading causes of maternal death worldwide.
Background The Brazilian Society of Cardiology described gestational hypertension as the presence of systolic blood pressure greater than or equal to 140 mmHg, diastolic pressure greater than or equal to 90mmHg, and headache or edema after the twentieth week of pregnancy. Placental-derived hormones appear to directly influence the BP trajectory. Furthermore, marginally elevated BP levels may increase the risk of antepartum and postpartum complications.
In phase one of the study period, participants were asked about demographics, obstetric history, socioeconomic condition, and smoking and nutrition status through a questionnaire. Phase Two was conducted six months after Phase 1, during which researchers obtained relevant data linked to gestational age, SBP and DBP measurements, all weight measurements during prenatal care, medication, and the presence of edema from physical/electronic medical records of the pregnant women.
A new strategy using a combination of statistical techniques and a trajectory model based on groups was adopted to study BP trajectory patterns in pregnant women. Mean SBP and DBP values of 110 mmHg and 70 mmHg, respectively, were observed. These values indicate a reduction in the second trimester, followed by a progressive increase in BP levels until the end of pregnancy.
