Abstract
Diabetes during pregnancy can adversely affect the health of women and infants. In this report, we provide an overview of the state of the science, and highlight Centers for Disease Control and Prevention (CDC) activities related to (1) surveillance of preexisting and gestational diabetes mellitus (GDM); (2) preconception care for women with preexisting diabetes; (3) postpartum diabetes screening among women with GDM-affected pregnancies; and (4) preventing the progression to Type 2 diabetes among women with GDM-affected pregnancies through lifestyle intervention programs. Improving preconception care, increasing postpartum diabetes screening rates, and promoting lifestyle interventions in the postpartum period all provide opportunities to improve the health of women and their infants.
