               【摘要】 背景 本研究团队前期分别开发了针对初产妇和经产妇的产后压力性尿失禁(SUI)风险预测模型,
           旨在早期识别孕产妇 SUI 的高危人群并提供有效干预,但尚未进行外部验证。目的 外部验证前期开发的产后 SUI 风
           险预测模型,探索该模型在临床应用的可能性。方法 于 2020 年 7—9 月在南方医科大学深圳医院、香港大学深圳医
           院进行电话随访,通过电子病历系统选取产后 6 个月的产妇作为验证组进行产后 SUI 风险预测模型的外部验证。使用
           电子医疗记录收集研究对象年龄、身高、妊娠前体质量、流产史和分娩史的相关信息;并通过电话随访调查研究对象
           产后 6 个月 SUI 发生情况。采用受试者工作特征(ROC)曲线下面积(AUC)和 Hosmer-Lemeshow 拟合优度检验分别
           评价产后 SUI 风险预测模型区分度和校准度。结果 最终纳入 298 例研究对象为验证组,其中初产妇 203 例(68.1%),
           经产妇 95 例(31.9%)。初产妇队列中,非 SUI 者 158 例,SUI 者 45 例。经产妇队列中,非 SUI 者 72 例,SUI 者 23 例。
           产后 SUI 风险预测模型在初产妇外部验证人群中 AUC 为 0.719〔95%CI(0.643,0.795)〕,在经产妇外部验证人群
           中 AUC 为 0.833〔95%CI(0.738,0.928)〕。Hosmer-Lemeshow 拟合优度检验提示产后 SUI 风险预测模型在初产妇人
                         2
                                                                     2
           群中校准欠佳(χ =34.11,P<0.001),而在经产妇人群中拟合度良好(χ =9.62,P=0.293)。结论 初产妇产后 SUI
           预测模型能有效区分患者是否发生产后 SUI,但尚需进一步更新以提高模型的外部适用性;经产妇产后 SUI 预测模型
           具有可接受的外部效能,鼓励将其作为产后早期盆底康复干预的评估工具进行推广。

               【Abstract】 Background Our research team developed two prediction models of postpartum stress urinary
           incontinence(PSUI),one for primiparas,and the other for multiparae,aiming at early identifying women at high risk of
           PSUI,and providing effective interventions,but they have not yet been externally validated. Objective To externally validate
           the risk prediction models of PSUI previously developed by us to assess their clinical applicability. Methods This study was
           conducted between July and September 2020. Participants were 6-month postpartum women(validation group) who were
           selected from the electronic medical record system of Shenzhen Hospital of Southern Medical University,and the University of
           Hong Kong-Shenzhen Hospital. Information about age,height,pre-pregnancy weight,abortion history,and delivery history
           was collected from the electronic medical record system of the two hospitals. A telephone follow-up was conducted to investigate
           the incidence of stress urinary incontinence within 6-month postpartum. The area under the receiver operating characteristic curve
           (AUC) was computed to estimate the value of the predictive models in discriminating PSUI. Hosmer-Lemeshow goodness-of-fit
           test was used to examine the calibration of the prediction models. Results A total of 298 cases were included,and 203 of them
