Per Executive Order 14434 , federal agencies are now using "Super Intelligence" (SI) in place of "Artificial Intelligence" (AI). You may see both terms across NIH content during this transition.

Pregnancy and Perinatology Branch (PPB)

Overview/Mission

PPB’s goals are to improve the health of women before, during, and after pregnancy; increase infant survival; and ensure the long-term health of mothers and children. Specifically, the branch supports research to understand fetal development and improve ways to diagnose, treat, and prevent diseases during pregnancy and in newborns.

As the focal point for NICHD extramural research and training in maternal-fetal medicine, neonatology, and related fields, branch staff also engage with and support investigators to identify knowledge gaps and opportunities for scientific advancement.

  • Improving Health Before, During, and After Pregnancy: Includes research on maternal health from pre-pregnancy, through pregnancy, and postpartum, including maternal morbidity and mortality
  • Reducing Preterm Labor and Birth and Other Birth Complications: Studies factors affecting the initiation and completion of labor, including the physiology, endocrinology, and medical management of birth
  • Increasing Infant Survival, Free from Disease and Disability: Addresses causes, prevention, treatment, and medical management of conditions associated with or resulting from birth and the newborn period
  • Ensuring the Long-Term Health of Mothers and Children: Seeks to understand aspects of birth, newborn, and infant care that may influence long-term health
  • Global Network for Women's and Children's Health Research: Supports and conducts clinical trials on cost-effective and sustainable interventions to improve maternal and infant health outcomes globally, inclusive of US populations
  • Human Placenta Project: Supports improvement to existing and development of new technologies for real-time assessment of placental development across pregnancy
  • Implementing a Maternal health and PRegnancy Outcomes Vision for Everyone (IMPROVE) Initiative: Supports activities to reduce preventable causes of maternal death and improve maternal health; PPB leads and coordinates this NIH-wide effort
  • Maternal-Fetal Medicine Units (MFMU) Network: Conducts clinical research to reduce maternal morbidity, fetal, and infant morbidity related to preterm birth, fetal growth anomalies, and pregnancy complications, and to provide the rationale for evidence-based, cost-effective obstetric practice  
  • Neonatal Research Network (NRN): Conducts clinical trials and observational studies to improve the chances for survival without neurodevelopmental impairment for infants born premature, low-birth weight, or with other serious conditions
  • Advancing Clinical Trials in Neonatal Opioid Withdrawal Syndrome (ACT NOW): Informs the clinical care of infants exposed to opioids in the womb; part of the NIH-wide Helping to End Addiction Long-term® Initiative
  • Stillbirth Research Consortium: Brings together four research centers and a data coordinating center to understand the causes of stillbirth, develop tools for its prediction and prevention, and test new clinical care strategies, guided in part by input from People With Lived Experiences

  • Extremely Preterm Birth Outcomes Tool (current link: https://www.nichd.nih.gov/research/supported/EPBO). This tool shows the range of possible outcomes for infants born extremely preterm. The outcomes are based on data from infants born between 22-25 weeks of pregnancy at U.S. hospitals in the NRN between 2006 and 2012.
  • Research Challenges and Competitions: These mechanisms encourage research, development, and innovation among communities that do not traditionally apply for funding support. PPB leads and has led several challenges related to improving maternal health.
  • PPB-funded studies available in NICHD’s Data and Specimen Hub (DASH), including data from the Global Network for Women's and Children's Health Research, MFMU Network, National Infant Sleep Position Study, and Stillbirth Collaborative Research Network
