Abstract：Objective: To analyze the correlation between fetal growth restriction and abnormal umbilical artery blood flow and the related factors affecting fetal growth. Methods: A total of 120 pregnant women with fetal growth restriction treated in our hospital from January 2019 to January 2021 were selected as the observation group and 100 normal pregnant women as the control group. The ratio of systolic peak to diastolic peak of umbilical artery blood flow (S/D), blood resistance index (RI) and blood pulsation index (PI) of the two groups were observed, various factors leading to fetal growth restriction were analyzed, and statistically significant factors were included in multivariate logistic regression analysis to analyze the relevant independent risk factors of fetal growth restriction. Results: The indexes of S/D, PI and RI in the observation group were significantly higher than those in the control group (P<0.05); the results of univariate and multivariate logistic regression analysis showed that anemia, placental abnormality and umbilical cord abnormality were independent risk factors for fetal growth restriction. Conclusion: Pregnant women with fetal growth restriction in the abdomen will have obvious abnormalities in umbilical artery blood flow, and their blood flow resistance will also increase significantly. Anemia, placental abnormality, umbilical cord abnormality and fetal membrane abnormality are independent risk factors leading to fetal growth restriction. More clinical attention should be paid to this type of condition in pregnant women.
