Infant Mortality Comparisons a Statistical Miscarriage

A: U.S. infant mortality rates (deaths of infants <1 year of age per 1,000 live births) are sometimes cited as evidence of the failings of the U.S. system of health care delivery. Universal health care, it’s argued, is why babies do better in countries with socialized medicine.

But in fact, the main factors affecting early infant survival are birth weight and prematurity. The way that these factors are reported — and how such babies are treated statistically — tells a different story than what the numbers reveal.

Low birth weight infants are not counted against the “live birth” statistics for many countries reporting low infant mortality rates.

According to the way statistics are calculated in Canada, Germany, and Austria, a premature baby weighing <500g is not considered a living child.

But in the U.S., such very low birth weight babies are considered live births. The mortality rate of such babies — considered “unsalvageable” outside of the U.S. and therefore never alive — is extraordinarily high; up to 869 per 1,000 in the first month of life alone. This skews U.S. infant mortality statistics. …
