Clinical trials of intensive metabolic care have demonstrated that malformation rates similar to those in the nondiabetic population can be achieved with meticulous preconceptional glycemic control. [31] Subsequent trials comparing a preconceptional intensive metabolic program to standard treatment have demonstrated lowered rates of perinatal mortality (0% vs 7%) and congenital anomalies (2% vs 14%). In addition, when the preconceptional counseling program was discontinued, the congenital anomaly rate increased by over 50%. [34]
