Abstract To i analyze the related influencing factors of the adverse pregnancy outcomes of high-risk pregnant women. Methods: The clinical data of 1227 pregnant women who had established their "Mother and Child Health Handbook" from January 2013 to December 2020 were collected retrospectively. These women were divided into group A (women with high-risk pregnancy) and group B (women without high-risk pregnancy) according to the screening table of high-risk factors of pregnancy in Beijing when their "Mother and Child Health Handbook" was established. The general clinical data and the pregnancy outcomes of the women in the two groups were statistics analyzed. The risk factors of the adverse pregnancy outcomes of the women in group A were analyzed. Results: The rates of premature delivery (5.9%), adverse fetal outcomes (23.8%), and dystocia (21.4%) of the women in group A were significantly higher than those (2.5%, 18.3%, and 16.9%) of the women in group B. In group A, the age (39.1±0.8 years old) and the pre-pregnancy body mass index (BMI) (24.4±0.4 kg/m2) of the women with adverse pregnancy outcomes were significantly higher than those (34.2±0.6 years old and 22.3±0.1kg/m2) of the women without adverse pregnancy outcomes (all P<0.05). Multivariate logistic regression analysis showed that the age ≥35 years old and the abnormal pre-pregnancy BMI of the high-risk pregnant women were the independent risk factors of their adverse pregnancy outcomes (P<0.05). Conclusion: The age ≥35 years old and the abnormal pre-pregnancy BMI y of the high-risk pregnant women are the independent risk factors of their adverse pregnancy outcomes.
