妊娠糖尿病の分類案

Pregnancies complicated by diabetes are at increased risk for adverse perinatal outcomes. The American College of Obstetricians and Gynecologists recommend universal screening for gestational diabetes mellitus during pregnancy at 24 to 28 weeks gestation. However, there is controversy on the utility of screening or identifying patients with early gestational diabetes mellitus. In this clinical perspective, we provide an evidence-based classification of diabetes in pregnancy (i.e., diagnostic criteria for standard gestational diabetes mellitus versus early gestational diabetes mellitus versus pregestational diabetes mellitus) to help define subgroups along the spectrum of glucose intolerance/insulin resistance to inform future outcome-based studies.
