Evaluating for Type-2 Diabetes in the Very Early Postpartum Period

This will be a prospective cohort study conducted at Winthrop-University Hospital. Women 18 years old or older who delivered a child or fetus within the previous 4 days at either hospital who also were diagnosed with GDM during the pregnancy will be eligible for participation. Women will be excluded if they have issues that would interfere with administration of a GTT, are unable /unwilling to provide informed consent, or cannot follow up. Anticipated enrollment will be 250 women at each study site. While still hospitalized two to four days postpartum, subjects will undergo a 75-gram, 2-hour GTT and have blood tested for hemoglobin A1c and glucose levels. They will be reminded to do the recommended GTT 6-12 weeks after delivery. Maternal, neonatal, and obstetric characteristics will be collected, including the any GTT results. The results of the in-hospital GTT will be compared to the result of the GTT taken 6-12 weeks postpartum and tested for correlation.
