Research On Advanced Diagnostics and Management of All Pregnancies to Prevent Stillbirth (ROADMAPS)

The primary objective of the Stillbirth Research Consortium (SBRC) longitudinal cohort study is to develop and evaluate a robust multivariable prediction model to identify pregnancies at \<14 weeks gestation that are at increased risk of stillbirth or fetal growth restriction (FGR), often reflecting underlying placental dysfunction. Secondary objectives include: * To evaluate placental pathology among cases and selected controls using standardized Amsterdam criteria. * To identify key aspects of perinatal nutrition contributing to placental dysfunction * To determine relationships between maternal biomarkers, placental pathology and energetics, with the goal of identifying biomarkers predictive of placental dysfunction * To develop a risk stratification model for pregnancies complicated by decreased fetal movements (DFM)
