What this Trial Is About
This research gathers data and biological samples from pregnant women to study prematurity, preeclampsia, and other pregnancy complications. It combines information from four original studies involving women at different stages of pregnancy, including those with low risk and those diagnosed with preeclampsia. The goal is to better understand early onset preeclampsia and related conditions using medical, social, obstetrical, and ultrasound data along with biological markers and genetics. Participants in the biobank provide blood and urine samples along with detailed clinical and demographic information. The studies include women pregnant with singletons or twins at various early gestational ages, some randomized to receive low-dose aspirin or placebo. Ultrasound examinations and blood pressure measurements are also part of the data collection, with access to medical records for pregnancy outcomes and newborn health. Women in the biobank undergo assessments including blood sample collection, urine testing, blood pressure monitoring, and ultrasound scans. Researchers use this information to measure outcomes such as early onset preeclampsia diagnosed between 20 and 34 weeks, severe preeclampsia, fetal growth restriction, spontaneous preterm birth, and fetal anomalies. The study started in 2015 and plans to continue until 2028, offering long-term follow-up of pregnancy complications and their outcomes.
