Abstract：OBJECTIVE To analyse the maternal adverse pregnancy outcomes in Lanzhou from 2016 to 2021,to understand the high-risk factors for adverse maternal pregnancy outcomes,and to provide an important reference for in-depth research on the prevention and treatment of adverse pregnancy outcomes and the improvement of eugenics.METHODS The maternal case questionnaires(a total of 184 535 cases)of inpatient pregnancies from 2016 to 2021 in 4 hospitals monitoring critical maternal health in Lanzhou were extracted from the National Maternal and Child Health Monitoring Information System.RESULTS The lower the maternal education level,the lower the risk of low birth weight.The risk of low birth weight was greater when the mother was sin-gle/divorced/widowed.Low education level,more pregnancies and births,and older women were at greater risk of giving birth to large babies.The lower the education level,the more fetal and gluteal presentations during delivery,the more miscarriages,the num-ber of births,and the number of previous cesarean sections,the higher the risk of fetal stillbirth.The lower the risk of stillbirth was for fetuses who opted for cesarean section at delivery.The risk of preterm birth increased with lower education level,hip,shoulder and mixed presentation during delivery,single/divorced/widowed,older age,and more pregnancies and births.CONCLUSION The ad-verse pregnancy outcome of pregnant women in Lanzhou is not optimistic,and the adverse pregnancy outcome is affected by many factors.Pregnant women themselves and medical institutions should pay attention to adverse pregnancy outcomes and related risk fac-tors,take a variety of effective measures to prevent and control,reduce the occurrence of adverse pregnancy outcomes.
