Study design:

Sequential 

研究目的:

(1)利用我院常规产前产前电子病历数据,收集孕早期及孕中期的临床特征、实验室检查结果和既往病史信息,构建孕妇GDM发生的早期预测模型。 (2)采用机器学习方法,将数据集划分为训练队列和验证队列,评估模型的区分度、校准度和临床应用价值,并与传统Logistic回归模型进行比较。 (3)探索影响GDM发生的主要危险因素,为制定孕早期高危评估与精细化管理策略提供依据。  

Objectives of Study:

(1) Using routine prenatal electronic medical record data from our hospital, collect clinical characteristics, laboratory test results, and previous medical history information during early and mid-pregnancy to construct an early prediction model for the occurrence of GDM in pregnant women. (2) Apply machine learning methods to divide the dataset into training and validation cohorts, assess the model's discrimination, calibration, and clinical utility, and compare it with the traditional Logistic regression model. (3) Explore the main risk factors influencing the occurrence of GDM to provide a basis for developing early pregnancy high-risk assessment and refined management strategies.
