The California Diabetes and Pregnancy Program (CDAPP) provides comprehensive technical support and education to medical personnel and community liaisons to assist in promoting improved pregnancy outcomes for high-risk pregnant women with pre-existing diabetes and women who develop diabetes while pregnant; gestational diabetes mellitus (GDM). These medical providers who undergo standardized training and provide direct patient care to women with diabetes while pregnant become know as Sweet Success Affiliates. Diabetes is a complication for up to 7-14% of pregnant women. The program’s goal is to reduce maternal and infant morbidity and mortality for this high risk group to approximate the outcomes of the low–risk perinatal population.
