california birth defects monitoring program

The California Birth Defects Monitoring Program (CBDMP) has been an active ascertainment, population based registry since 1982 when the California State Legislature authorized the California Birth Defects Monitoring Program (CBDMP) to collect data on birth defects, stillbirths, and miscarriages. CBDMP currently monitors over 150,000 births in 10 counties—approximately 30% of the births in California, which are representative of the state's population.  The CBDMP registry data are used for ongoing surveillance to monitor rates and trends of select birth defects and to provide outcome data for the pregnancy blood samples included in the California Biobank Program. The Program receives funding from the California Birth Defects Monitoring Fund.
