Preterm births in China between 2012 and 2018: an observational study of more than 9 million women.

ABSTRACT:

Background

Preterm birth rates have increased significantly worldwide over the past decade. Few epidemiological studies on the incidence of preterm birth and temporal trends are available in China.
