National Birth Defects Prevention Network
The National Birth Defects Prevention Network (NBDPN) is a volunteer-based organization that addresses the issues of birth defects surveillance, research, and prevention under one umbrella by maintaining a national network of state and population-based birth defects programs. Members include public health officials, epidemiologists, academics, parents, and others committed to understanding factors that may lead to birth defects, identifying strategies for reducing birth defects, and working to prevent potential secondary disabilities. NBDPN provides members with guidance in data coding, presentation, and statistical techniques as applied to birth defects. It also publishes annual birth defects state profiles for all states.
