Abstract To explore the influence factors of the preterm delivery and low birth weight of the newborn of women with assisted reproductive technology(ART). Methods: 150 pregnant women with ART who had delivered in hospital from October 2018 to February 2022 were selected in this study. The situation of preterm delivery and low birth weight of the newborn of these women were counted. The baseline data and the situations of ovarian stimulation and embryo transplantation of the pregnant women with different pregnancy outcomes were collected. The influencing factors of the premature birth and the low body weight of the newborn of the women were analyzed by logistic regression. Results: There were significant differences in the value of body mass index(BMI), the number of pregnancies, and the percentages of the pregnancy induced hypertension and the premature rupture of membranes between the women with and without preterm delivery. There were significant differences in the BMI value, the number of pregnancies, and the percentage of premature rupture of membranes of the women between their newborn with and without low birth weight(P＜0.05). Logistic multiple factor regression analysis showed that the BMI value, the number of pregnancies, the pregnancy induced hypertension, and the premature rupture of membranes of the women with ART were the influencing factors for their preterm delivery. The BMI value, the number of pregnancies, and the premature rupture of membranes of the women with ART were the influencing factors for their newborn low birth weight(P＜0.05). Conclusion: The occurrences of premature birth and low body weight of the newborn of the pregnant women with ART are affected by many factors, so the reasonable intervention measures should be formulated for these women according to the influencing factors to reduce the occurrence of the adverse outcomes of their newborn.
