摘　　要：目的探讨基于Logistic回归分析的子宫异常出血患者子宫内膜息肉发生的预测模型,为子宫内膜息肉的临床诊治提供参考依据。方法选取330例子宫异常出血患者,按照是否发生子宫内膜息肉将患者分为发生组(99例)与未发生组(231例)。对两组患者的基本情况[年龄、体质量指数(BMI)]、孕产次情况、月经情况、避孕情况、合并症情况进行观察和比较。结果预测子宫异常出血患者子宫内膜息肉发生的预测模型:P=1/[1+exp(4.227-1.165X_(1)-1.817X_(2)-2.029X_(3)-2.120 X_(4)-2.080X_(5))];Hosmer-Lemeshow拟合优度检验结果显示χ^(2)=7.993,P=0.434。结论年龄、产次、子宫内膜炎、子宫肌瘤和口服避孕药是子宫异常出血患者子宫内膜息肉发生的危险因素,基于Logistic回归分析构建的子宫异常出血患者子宫内膜息肉发生的预测模型拟合情况良好,具有临床应用价值。Objective To explore a predictive model for the occurrence of endometrial polyps in patients with abnormal uterine bleeding based on logistic regression analysis,and provide reference for the clinical diagnosis and treatment of endometrial polyps.Methods 330 patients with abnormal uterine bleeding were selected and divided into the occurrence group(99 cases)and the non-occurrence group(231 cases)according to whether endometrial polyps occurred.The basic information(age,body mass index(BMI)),pregnancy times,menstruation,contraception and comorbidities of the two groups were observed and compared.Results A predictive model for predicting the occurrence of endometrial polyps in patients with abnormal uterine bleeding:P=1/[1+exp(4.227-1.165X_(1)-1.817X_(2)-2.029X_(3)-2.120 X_(4)-2.080X_(5))];The results of the Hosmer-Lemeshow goodness of fit test show that;,=7.993,P=0.434.Conclusion Age,parity,endometritis,uterine fibroids,and oral contraceptives are risk factors for the occurrence of endometrial pol,s in patients with abnormal uterine bleeding.Based on logistic regression analysis,a predictive model for the occurrence of endometrial pol,s in patients with abnormal uterine bleeding is well fitted and has clinical application value.
