International Infant Mortality
In 2008, the U.S. infant mortality rate (6.6 infant deaths per 1,000 live births) was higher than the rate for many other industrialized nations. Differences in infant mortality rates among industrialized nations may reflect variation in the definition, measurement, and reporting of fetal and infant deaths. However, recent analyses of the differences in gestational age-specific infant mortality indicate that this disparity is most likely related to the high rate of preterm birth in the US.1 Infants born preterm (or less than 37 weeks gestation) have higher rates of death and disability than infants born at term (37 weeks gestation or more).2 Although the United States compares favorably with European countries with respect to the survival of preterm infants, the higher rate of preterm birth in the U.S. overall significantly impacts the infant mortality rate.
In 2008, the U.S. ranked 28th in infant mortality among industrialized nations. In comparison, Iceland and Sweden, both with infant mortality rates of 2.5 deaths per 1,000 live births, were ranked first, followed by Finland and Japan, both with a rate of 2.6 deaths per 1,000 live births. The U.S. did not always rank this low; in 1960, it ranked 12th, with Iceland, Norway and the Netherlands reporting the three lowest rates among industrialized nations that year.
