Correlation of Vitamin D Levels in Early Pregnancy With Gestational Diabetes and Pregnancy Outcomes

GDM

Explore the specific correlation between different concentration levels of vitamin D in early pregnancy and blood glucose levels at each time node of OGTT, the correlation between different concentrations of vitamin D levels and A1 and A2 diabetes in pregnancy, and the impact on maternal and infant outcomes , And provide a basis for the prevention and treatment of GDM.

1. According to the diagnostic criteria of GDM proposed by the International Association for the Study of Diabetes and Pregnancy (IADPSG), the 18-45-year-old pregnant women who were filed and delivered by the Obstetrics Department of Beijing Friendship Hospital from September 2022 to September 2024 were selected to collect their early pregnancy (pregnancy 1- 3 months) Vitamin d level, divided into three groups: A (\<20 ng/ml), B (20\ \<30 ng/ml), and C (≥30 ng/ml), compare the early pregnancy (1-3 months of pregnancy) Differences in vitamin D levels. 2. Follow-up patients with gestational diabetes mellitus are divided into type A1 gestational diabetes patients (GDM 1 group) and type A2 gestational diabetes patients (GDM 2 group) according to whether participant are treated with insulin, and study vitamins through multiple linear and logistic regression models The relationship between D level and GDM and follow-up pregnancy outcome 3. Analyze the relationship between the level of vitamin D in early pregnancy and pregnancy complications, such as whether it is combined with premature rupture of membranes, hypertension during pregnancy, whether it is a cesarean section, whether it is a giant baby, whether there is asphyxia in newborns, etc.
