Selected Birth Defects Data from Population-based Birth Defects Surveillance Programs in the United States, 2006 to 2010: Featuring Trisomy Conditions

This is part of the 2013 Annual Report of the National Birth Defects Prevention Network (NBDPN), published in a special issue of Birth Defects Research Part A: Clinical and Molecular Teratology (Volume 97, Issue 11). This Brief Report and supporting information report state-specific data from 41 participating population-based registries on prevalence numbers for 47 congenital anomalies from January 1, 2006 through December 31, 2010, as well as more detailed data on trisomy 21 (commonly referred to as Down's syndrome), trisomy 18, and trisomy 13. Data for trisomy are broken down by maternal age in the brief report; the accompanying data brief presents data on various anomalies, broken down by race/ethnicity for each defect. Collection of data on live births only, live and stillbirths, or all pregnancy outcomes differs by state. As with other annual reports, there is also an accompanying directory of state birth defects surveillance programs.
