Here we conducted comprehensive epidemiological analyses on 121,090 pregnant women and their 124,025 neonates from the ZEBRA Chinese prospective maternity cohort. We find that unit incremental exposure in PM 2.5 , O 3 , and green space can change the risks of maternal pregnancy-induced cardiovascular diseases (CVDs) by 7.3% (95% confidence interval 6.4–8.2%), 2.7% (2.2–3.3%), and –3.6% (1.8–5.2%), respectively. Maternal cardiovascular and haematological diseases significantly aggravate the risk of adverse pregnancy outcomes (APOs, including congenital heart disease) by 69.3% (61.5–77.5%), and also modify the environment-APO risk associations by amplifying the hazards of air pollution and weakening the protective effect of greenness accessibility. Our research supports several Sustainable Development Goals by providing first-hand epidemiological evidence and clinical guidance for maternal and neonatal health protection.
