title: Contribution of birth defects to infant mortality among racial/ethnic minority groups, United States, 1983.
abstract: Linked birth/infant death data from the National Center for Health Statistics (NCHS) for the 1983 U.S. birth cohort, the latest year for which linked data were available, were evaluated in order to assess the contribution of birth defects to infant mortality among racial/ethnic groups. Of the 34,566 singleton infant deaths with specified birth weight born to U.S. residents, birth defects were listed as an underlying cause of death for 7,678 (22.2%) infants and as a contributing cause of death for an additional 1,006 (2.9%) infants. Infant mortality rates due to birth defects were highest among American Indians (2.9 deaths/1,000 live births), followed by Asians and Hispanics (2.6), and blacks (2.5). Proportional mortality due to birth defects varied among racial/ethnic groups; it was greatest among Asians (27%), followed by whites (25%), Hispanics (24%), American Indians (18%), and blacks (13%). Also, infant mortality rates due to birth defects were high among minority infants of low birth weight, particularly among those born weighing between 1,500 and 2,499 g. Within this group of infants, proportional mortality due to birth defects ranged from 52% among Asians to 29% among blacks. These data indicated that birth defects were an important contributor to infant mortality among all racial/ethnic groups. Birth-defects surveillance systems should be used to evaluate whether racial/ethnic differences in infant mortality from birth defects are due to differences in incidence and/or survival among minority infants with birth defects.
