For at east 20 years, birth defects have been the leading cause of infant mortality n the United States.
Some studies have reported higher rates for black infants than white infants of mortality due to birth defects. while other studies have reported no black-white differences.
The authors analyzed the effect on these rates of a change in the way the National Center for Health Statistics (NCHS) tabulates « race » for newborns.
The authors calculated infant morta ty rates due to birth defects for 1980 1993 using two standard methods of assigning newborns to'racial « categories : a trace of child » algorithm and the « race of mother » approach currently used by NCHS.
From 1980 through 1993, birth defect-specific infant mortality rates (BD-IMRs) were significantly higher for black nfants than white infants 12 of the 14 years by « race of mother » and only 5 of 4 years by « race of child. » Calculation of BD-IMRs by « race of mother » reduced the rate for white infants and increased the rate for black infants in each of the 14 years.
The choice of method for assigning newborns to « racial » categories had a progressively greater effect over time on the black-white gap in BD-IMRs.
Calculations of trends in « race » - spec Sc BD-IMRs by may vary substantially by whether « race of mother » or « race of child » is used.
Identifying the method of tabulation is mperative for appropriate comparisons and interpretations.
