Objective To understand the effect of air pollution on adverse pregnancy outcomes,and to provide the reference for reducing adverse pregnancy outcomes.Methods Using the birth registration data of hospitals at all levels in the urban area of Suzhou from 2010-1-1 to 2019-12-31,the incidence of adverse pregnancy outcome in each year was calculated.The effects of six kinds of pollutants(PM2.5,PM10,CO,SO2,O3 and NO2)on adverse pregnancy outcomes were analyzed by case control and logistic regression.Results The incidence of adverse pregnancy outcomes in the past ten years ranged from 15.09%to 17.88%.The top three were macrosomia,premature delivery and low birth weight infants.The influences of infant gender,maternal age,census register,occupation,number of fetuses,fetal position,mode of delivery,delivery season and number of prenatal examinations on adverse pregnancy outcomes were statistically significant.Except NO2,the exposure of PM2.5,PM10,CO,SO2 and O3 were associated with the occurrence of adverse pregnancy outcomes.Conclusion The exposure of air pollutants before and after pregnancy may have adverse effects on adverse pregnancy outcomes.
