Abstract To analyze the occurrence of ectopic pregnancy of pregnant women with different levels of serum β-human chorionic gonadotropin (β-hCG). Methods: 85 pregnant women with ectopic pregnancy in study group and 85 normal in control group pregnant women from September 2017 to September 2022 were collected retrospectively. The clinical data and the serum β-hCG level of the women were compared between the two groups. Multivariate logistic regression analysis was used to analyze the risk factors of ectopic pregnancy. These women were further divided different groups according to their β-hCG level, and potential category analysis was used to compare the distributions of the risk factors of the ectopic pregnancy occurrence of the women among the different groups. Results: The pelvic inflammation history, the number of pregnancies, the number of induced abortion, the history of ectopic pregnancy, the history of pelvic surgery, the history of cesarean section, the history of intrauterine device used, the serum β-hCG level <1500U/L of the pregnant women were all the independent risk factors of their ectopic pregnancy occurrence. The probability of ectopic pregnancy occurrence of the women had increased with the decrease of their serum β-hCG level. Cluster analysis showed that the incidence of ectopic pregnancy (76.5%) of the women with β-hCG level <1500U/L was significantly higher than that (25.8%) of the women with β-hCG level ≥1500U/L, and the proportion of more risk factors of ectopic pregnancy the women with β-hCG level <1500U/L was significantly higher than that of the women with β-hCG level ≥1500U/L (all P＜0.05). Conclusion: The probability of ectopic pregnancy occurrence of the pregnant women with different level of serum β-hCG has variant. The probability of ectopic pregnancy occurrence of the pregnant women with serum β-hCG level <1500U/L or the pregnant women with more risk factors has increased.
