Baseline demographic data, maternal characteristics that have previously been shown to be associated with type 2 DM, and obstetric and reproductive history will be collected at the time of consent or at a maximum of two weeks after consent. The mailing address and telephone number of the patient and their family physician will also be obtained. A chart abstraction will be performed approximately 30 days after the expected date of confinement (EDC) to determine if a live birth occurred and the weight and gender of the baby will be abstracted.
