Each year across the world, one million preterm babies die within the first 28 days of life. Of the 14 million more preterm babies who survive, many are faced with a lifetime of serious health complications.

The UCSF Preterm Birth Initiative (PTBi) is a multi-year research effort working to reduce the burden of prematurity in California and East Africa. PTBi engages in holistic, place-based research and respectful care across the reproductive life course.
