Shanghai Clinical Cohort of Hyperglycemia in Pregnancy

Recruiting now

Conditions studied: Hyperglycemia in Pregnant Diabetic Patients, Gestatiaonl Diabetes Mellitus

In brief

Establish a high-quality clinical cohort of hyperglycemia in pregnancy. Develop subtype-specific, end-to-end standards for diagnosis, treatment, and follow-up across the preconception, pregnancy, and postpartum phases. These standards will lay a solid foundation for efficient, high-quality clinical research.
