Effect of Early Lifestyle Intervention on Perinatal Outcomes in High-risk Women for Gestational Hyperglycemia

This study aims to explore whether early intervention for high-risk groups of gestational hyperglycemia can improve insulin resistance and effectively prevent the occurrence of GDM, and evaluate which pathophysiological subtypes of GDM have the best effect on improving maternal and fetal adverse prognosis, so as to provide evidence for stratified management and individualized clinical intervention of high glucose groups in pregnancy
