Subtypes of Gestational Diabetes Mellitus Are Differentially Associated With Newborn and Childhood Metabolic Outcomes

Diabetes CarePublished Secondary analysis of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study and HAPO Follow-Up Study

Authors' conclusion

GDM subtypes are differentially associated with newborn and childhood outcomes. Better characterizing individuals with GDM could help identify at-risk offspring to offer targeted, preventative interventions early in life.
