Decline of Infant Mortality in Vermont

CDC, Apr 05, 2007

From 1980 to 1995, IMBD declined in every state and Vermont had the greatest decline in IMBD, moving from the highest category (2.7-3.2 per 1000 live-born infants) to the lowest (1.1-1.4).

Infant mortality has declined in the United States because of advances in public health and clinical medicine. Birth defects are the leading cause of infant mortality, but infant mortality attributable to birth defects (IMBD) has not declined as rapidly as overall infant mortality. From 1968 to 1995, the proportion of IMBD increased from 14.5% to 22.2%. To help focus efforts to reduce IMBD, CDC examined trends in IMBD, highlighting demographic, geographic, and defect-specific mortality rates. This report summarizes the results of this analysis, which indicate variation in rates for IMBD by sex, race/ethnicity, and state of residence.

The underlying cause-of-death for all infants (children aged less than 1 year) was obtained from U.S. public-use, multiple-cause mortality data tapes maintained by CDC. Birth defects in this study were classified according to the International Classification of Diseases, Clinical Modification, Ninth Revision, codes 740-759. The number of live births per year by the child's race and sex and mother's state of residence (including the District of Columbia) was determined from published natality statistics. The number of live births was 3,612,258 in 1980 and 3,899,589 in 1995 (3). Only births and deaths to U.S. residents were included in the analyses.
