Beijing Birth Cohort Study (BBCS)
The BBCS was a prospective pregnancy-birth cohort study of over 52,000 mother-child pairs in Beijing, China. Chinese women who were 8-13 weeks pregnant and planning to deliver in the Beijing Obstetrics and Gynecology Hospital were recruited between July 2017 and December 2021. All participants were followed up around 10 times during the second and third trimesters, every 2-4 weeks before 37 weeks of gestation and weekly after 37 weeks of gestation. All newborns delivered by the participants were followed-up for 3 years after birth to establish a database of early infant development.
