Population-based studies from other countries suggest a frequency similar to the United States. However, nations with a lower rate of premature births than that in the United States generally have a lower rate of NEC as well. For example, a large study of NICUs in Japan identified a 0.3% incidence of NEC, which is significantly lower than that in similar patient populations in the United States. [24]

An epidemiologic review of the disease in infants born at less than 32 weeks' gestation who survived past 5 days of life in Canada reported an incidence of 6.4%. [25]
