This study identified factors contributing to the rapid decline in infant mortality in New York City from 1989 to 1992.
Changes in birthweight distributions and in birthweight/age-cause-and birthweight/age/cause-specific mortality rates from 1988/89 (before the mortality reduction) to 1990/91 were identified from New York City vital statistics data.
Infant, neonatal, and postneonatal mortality of very-low-birthweight (<1500 g) and normal-birthweight infants decreased significantly.
The declines were almost entirely due to decreases in birthweight-specific mortality rates, rather than increased birthweights.
All races experienced most of these reductions.
Mortality decreased significantly for 6 causes of death.
These decreases were consistent with the birthweight/age groups experiencing mortality declines.
Widespread, multiple perinatal and postnatal factors contributed to the decline in infant mortality.
