ObjectiveTo analyze the influencing factors of adverse pregnancy outcomes in 200 elderly pregnant women.

MethodsThe pregnancy outcomes data of 200 elderly pregnant women were collected, the occurrence of adverse pregnancy outcomes was statistically analyzed, and the influencing factors of adverse pregnancy outcomes of elderly pregnant women were analyzed.

ResultsThe incidence rate of adverse pregnancy outcomes in 200 elderly pregnant women was 19.00%, followed by low birth weight infants(31.58%), preterm infants(26.32%), neonatal asphyxia(15.79%), macrosomia(15.79%), neonatal malformations(5.26%) and neonatal death(5.26%).The history of miscarriage, adverse pregnancy habits, planned pregnancy, pregnancy complications, pregnancy complications, passive smoking, multiple pregnancy and disease history before pregnancy were the single factor of affecting adverse pregnancy outcomes in elderly pregnant women(P < 0.05 to P < 0.01).The results of multivariate logistic regression analysis showed that the abortion history, pregnancy complications, pregnancy complications, passive smoking, multiple pregnancies, and pre-pregnancy disease history were the risk factors of adverse pregnancy outcomes in elderly pregnant women(P < 0.05 to P < 0.01).

ConclusionsThe incidence rate of adverse pregnancy outcomes in elderly pregnant women is high.The history of abortion, pregnancy complications, passive smoking, multiple pregnancies, and pre-pregnancy disease history are the risk factors of adverse pregnancy outcomes in elderly pregnant women.
