Welcome to the Oxford Maternal and Perinatal Health Institute

The Oxford Maternal & Perinatal Health Institute (OMPHI) was founded in 2009 under the aegis of the Green Templeton College, University of Oxford. We engage medical researchers, social scientists, and health management experts in some of the major issues affecting the health of mothers and newborn babies, particularly in resource-poor settings. We are running 4 large, global studies involving over 350 researchers from a wide range of countries: INTERGROWTH-21st, INTERBIO-21st, INTERPRACTICE, and INTERNDA.

Our research projects

The INTERGROWTH-21st project

The International Fetal and Newborn Growth Consortium for the 21st Century, or INTERGROWTH-21st, is a global, multidisciplinary network of more than 300 researchers and clinicians from 27 institutions in 18 countries worldwide and coordinated from the University of Oxford. The primary purpose of the project is the creation of new "prescriptive" standards describing normal fetal growth, preterm growth, and newborn nutritional status.

This website provides clinicians and researchers access to the INTERGROWTH-21st international standards. This package is comprised of new, globally-validated standards and practical training resources.

These standards are paired with an expanding Training Toolkit and a rich body of literature on our methods. Policymakers may be interested in learning our progress with dissemination.

A selection of INTERGROWTH-21st-related news articles is available on our News page.
