<qa>  What is the name of the study that was established by the Eunice Kennedy Shriver National InstituteThe Eunice Kennedy Shriver National Institute of Child Health and Human Development NICHD established the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be nuMoM2b to study women for whom the current pregnancy will lead to their first delivery nulliparas. About 40 of pregnant women in the United States are nulliparas. Because little or no information from previous pregnancy outcomes is available to guide assignment of risk or mitigating interventions, adverse pregnancy outcomes in nulliparas are especially unpredictable. The underlying mechanisms of adverse pregnancy outcomes such as preterm birth, preeclampsia, fetal growth restriction and stillbirth are interrelated and therefore will be evaluated as part of this study. The information gained will benefit women who are pregnant or who are considering pregnancy and their physicians. In addition, the knowledge will support future research aimed at improving care and health outcomes for a critical group of at-risk women who are currently understudied.
