Screening for Gestational Diabetes Mellitus: Challenges and Controversies
Gestational diabetes mellitus (GDM) is associated with several adverse outcomes for the fetus, newborn, and mother. Screening for and diagnosing GDM is accomplished through oral glucose tolerance testing. The American College of Obstetricians and Gynecologists (ACOG) has long advocated for a two-step testing approach that incorporates a screening test followed by a diagnostic test for those women who have a positive screening test. Recently, the International Association of Diabetes in Pregnancy Study Groups (IADPSG) has recommended that a simplified one-step testing approach be used to screen and diagnose GDM based on the results of the Hyperglycemia and Adverse Outcomes (HAPO) study. Although this approach has been adopted by the American Diabetes Association (ADA), considerable controversy remains regarding which approach is best. This program will review the different guidelines and recommendations as they relate to the diagnosis of GDM.
