The National Birth Defects Prevention Study (NBDPS) is one of the largest studies on causes of birth defects in the US. NBDPS included deliveries from 1997 to 2011. The Birth Defects Study to Evaluate Pregnancy exposureS (BD-STEPS) began with deliveries in 2014 and is ongoing.

Findings from each of these studies are published in a yearly newsletter that we send to women who took part in this study. The purpose of these newsletters is to inform the public of the Centers’ activities and current news about birth defects. You can find links to these newsletters below. We also will report our results on this webpage. Remember, all our findings pertain to groups of women; no one will be able to identify you from our reports or publications.
