Participating sites include Arkansas, California, Georgia (CDC), Iowa, Massachusetts, New York, and North Carolina.

Because many types of birth defects occur at such low rates, it is difficult to conduct studies that include enough babies with specific birth defects. BD-STEPS allows us the opportunity to create a study group large enough to determine what environmental, genetic, and behavioral factors might cause or contribute to specific birth defects.
