The INTERGROWTH-21st Project is a multicentre, multi-ethnic, population-based study. Recruitment for the first phase of the study took place between April 27, 2009 and March 2, 2014 in eight study sites: the cities of Pelotas (Brazil), Turin (Italy), Muscat (Oman), Oxford (UK), Seattle (USA), Shunyi County, Beijing (China), the central area of Nagpur (India) and the Parklands suburb of Nairobi (Kenya).

The INTERGROWTH-21st Project is based at the Oxford Maternal & Perinatal Health Institute (OMPHI), Green Templeton College, University of Oxford. The Project is supported by a generous grant from the Bill & Melinda Gates Foundation to the University of Oxford, for which we are very grateful.

Neurodevelopmental follow-up of babies from the original INTERGROWTH-21st study and its extension, INTERBIO-21st, are currently ongoing. Information about INTERBIO-21st is available here.
