Abstract: Among the various complications of pregnancy, preeclampsia (PE) is one of the major causes of maternal and fetal mortality and morbidity to this day. Unfortunately, there is still no effective cure of PE other than the delivery of the placenta. However, daily aspirin have been shown to effectively prevent PE in high-risk women when started before 16 weeks of gestation. It is imperative to identify women at risk for PE early in gestation. Several methods have been proposed, including the use of biophysical measurements. Studies on this topic show varying results, which can be partly due to differences in measurement techniques and in methodology. We conducted a prospective observational cohort study to estimate the performance of two biophysical parameters, measured with standardized techniques during the first trimester of pregnancy, for the prediction of PE. These two parameters are the body mass index (BMI) and the mean arterial blood pressure (MAP). We observed that the BMI, modeled as a continuous variable, and the MAP, measured using an automated device validated for pregnant women, of women in the first trimester of pregnancy are associated with the risk of developing PE. Therefore, these markers appear to be useful for the early prediction of PE and should be considered in a predictive model of PE for clinical use.
