A Risk Score for Prediction of Gestational Diabetesmellitus in China Using Routinely Collected Hospital Data

This project will recruit 6,608 pregnant women in the early stage of pregnancy in Beijing and across the country. Researchers (prenatal examination doctors) will collect the basic information of pregnant women and the results of early pregnancy laboratory tests through hospital systems (HIS and LIS systems). The dietary frequency and exercise information of pregnant women were collected through questionnaire surveys: A 75g oral glucose tolerance test (0GTT test) was conducted at 24-28 weeks. Follow-up was conducted until the completion of the 75gOGTT test, and the delivery outcomes were recorded. By making the subjects pay attention to their own physical conditions through the project, abnormalities can be detected early. At the same time, early prediction of gestational diabetes mellitus enables doctors and health physicians to identify high-risk groups for gestational diabetes mellitus (GDM) at an early stage and carry out early intervention, reducing GDM and related pregnancy complications, promoting the health of mothers and infants, and reducing the additional medical expenses that may be borne for GDM management and the overall medical expenditure of the country in the future.
