Brief summary
The aim of this study is to explore the diagnostic efficacy of oral glucose tolerance test in early pregnancy and establish the prediction model for gestational diabetes mellitus, so as to provide the optimal screening of gestational diabetes mellitus in the first trimester. The treatment started when the pregnancy was confirmed by transvaginal ultrasound (around 6 weeks of gestation) and continued until 42 days postpartum. The study is a single center, prospective cohort study. A total of 781 participants within 14 weeks of gestation were recruited.
Interventions
