Abstract
The Atlanta Birth Defects Case-Control Study data comprises information obtained from interviews with parents of 4,900 babies born with major birth defects and with the parents of 3,000 babies born without defects. The source of cases is the Centers for Disease Control's Metropolitan Atlanta Congenital Defects Program; the case-control study is population-based. Birth defects are classified into 92 groups and cross-tabulated by 105 exposure/risk factor variables; data from selected cross-tabulations are presented. The associations of each of the 105 exposure variables with all types of defects combined are presented, as are the associations of each of the 92 defect groups with the specific exposure variable, maternal diabetes. These data can be used to evaluate hypotheses arising from other sources, and for the purpose of “generating” hypotheses. The data describing all 92 × 105 cross-tabulations are available to other investigators on floppy disk; write to Chief, Birth Defects and Genetic Diseases Branch, Centers for Disease Control, Atlanta, Georgia 30333.
