China Multicenter Birth Cohort (CMBC)
The CMBC study was a nationally representative birth cohort study designed to investigate the effects of maternal environmental exposures on pregnancy outcomes and child health. The study recruited 7,000 mother-child pairs between September 2015 and September 2023 from seven cities across China. Mothers were aged 18 to 47 years who attended prenatal examinations or deliveries at participating hospitals. Participants were assessed during pregnancy and after birth to assess developmental and health outcomes.
