About this trial
A Multicenter Prospective Cohort Study to Identify Risk Factors and Develop a Diagnostic Prediction Model for Gestational Diabetes Mellitus, and to Evaluate the Effectiveness of Multidisciplinary Precision Health Interventions (GLOW Plan)
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Aged 18-40 years;
Pre-pregnancy BMI: 18.5 kg/m² < BMI < 28 kg/m²;
Able to read, understand and sign the informed consent form;
Receive prenatal care and deliver in the study hospital.
Disqualifiers
Twin or multiple pregnancies;
Pre-gestational diabetes mellitus (PGDM), including new-onset diabetes during pregnancy;
Poorly controlled pre-pregnancy chronic hypertension (BP ≥140/90 mmHg);
Complicated with severe liver/kidney diseases;
Trial population
A total of 1,000 pregnant women with antenatal care registration in the study hospital are enrolled, including 500 Gestational Diabetes Mellitus (GDM) cases (diagnosed via 75g OGTT at 24-28 weeks of gestation with ≥1 abnormal blood glucose value) and 500 normal controls. All participants meet: aged 18-40 years, pre-pregnancy BMI 18.5-28 kg/m², ability to sign informed consent, and prenatal care/delivery in the hospital. Those with multiple pregnancies, pre-gestational diabetes, poorly controlled hypertension, severe organ diseases, or poor compliance are excluded. Participants and their offspring complete perinatal and 2-year postnatal follow-ups.

Treatments tested in this trial
cgm
DeviceParticipants will wear a continuous glucose monitoring device to continuously record glucose levels throughout the study period, in addition to receiving standard prenatal care.
Behavioral Self-Monitoring of Blood Glucose
BehavioralParticipants will perform regular self-monitoring of blood glucose using a finger-prick glucose meter, along with standard prenatal care.
Control
Other interventionParticipants will receive standard prenatal care without additional glucose monitoring interventions
