Necrotizing enterocolitis mortality in the United States, 1979-85.

The Multiple Cause of Death Mortality data from the National Center for Health Statistics were analyzed to describe epidemiologic characteristics and trends in deaths related to necrotizing enterocolitis (NEC) among infants in the United States from 1979 to 1985. The average annual mortality rate (multiple cause mortality) for NEC was 13.1 deaths per 100,000 live births. NEC annual mortality rates decreased significantly during the study period for White and Black infants, male and female infants, and infants in the Northeast, North Central, and South regions. Black infants were approximately three times more likely to die from NEC than White infants, and the NEC infant mortality rate was highest in the South.
