Congenital Malformations Registry - 1996 Report
Section I
Demographic Characteristics of Children
Reported with Major Malformations
These tables are based on children resident in New York State who were live born in 1996 and 1997 and reported to the registry with major malformations. Since a new coding system began to be used in 1992, the list of major malformations has been revised (see Appendix 4). Thus, the prevalence in this report are not comparable to reports prior to 1992.
The overall occurrences of major malformations for the two years are 4.1% to 4.2% of live births. Male children have a higher rate of major malformations than female children (4.8% to 4.9% versus 3.3% to 3.4%, Tables 1a, 1b). This difference is consistent within different racial groups. The rates for major malformations are somewhat higher for black than for white children (4.7% to 5.0% versus 4.0% to 4.1%). The major malformation rate among children with residence at birth in New York State excluding New York City was slightly higher than children with residence at birth in New York City (4.2% to 4.3% versus 4.0% to 4.1%). The smaller number of births in the "other" racial category makes these rates difficult to interpret.
About 77% of children reported with major malformations have only one major malformation (Tables 2a, 2b). Since most children had one major malformation, the race-sex patterns seen for all major malformations are similar to the patterns seen in children with a single major malformation (Tables 3a, 3b). All race-sex groups for children with multiple major malformations showed little variation (Tables 4a, 4b).
