研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

1、整合抗凝药效、基因、心理状态、热带地区气候特征、代谢组学、免疫、内分泌、超声等多维数据,构建针对RPL妊娠不同时期的指标轨迹变化的动态风险预警模型。 2、验证阶段测试模型对基层医院数据的泛化能力,以服务基层医院。 3、建设海南省热带地区复发性流产专病数据库,构建“预测-干预-随访”全链条转化路径。  

Objectives of Study:

1、To integrate multi-dimensional data encompassing anticoagulant efficacy, genetic factors, psychological status, tropical climate characteristics, metabolomics, immunology, endocrinology, and ultrasonography, in order to construct a dynamic risk early-warning model. This model will track changes in indicator trajectories across different gestational periods in Recurrent Pregnancy Loss (RPL). 2、To validate the model by testing its generalizability with data from primary care hospitals during the verification phase, thereby extending its service utility to grassroots healthcare settings. 3、To establish a specialized RPL disease database for the tropical region of Hainan Province and develop a translational pathway encompassing the full cycle of "prediction-intervention-follow-up."
