Preterm-Related Infant Mortality* Rates, by Race/Ethnicity
of Mother  United States, 2000 and 2005

* Deaths among infants born at <37 weeks' gestation with cause of death that was a direct cause or consequence of preterm birth. Based on International Classification of Diseases, Tenth Revision, codes K550, P000, P010, P011, P015, P020, P021, P027, P070--P073, P102, P220--P229, P250--P279, P280, P281, P360--P369, P520--P523, and P77.

Per 1,000 live births.

§ Includes persons of Hispanic and non-Hispanic ethnicity.

Includes only three subpopulations: Puerto Rican, Mexican, and Central and South American. A reliable rate could not be computed for Cuban women because of small numbers of preterm-related infant deaths in that subpopulation.

From 2000 to 2005, preterm-related infant mortality rates increased significantly (p<0.05) for the total population and for non-Hispanic white, non-Hispanic black, Hispanic, Asian/Pacific Islander, and Mexican women. In 2005, preterm-related infant mortality rates were approximately three times higher for non-Hispanic black women (6.26) and nearly twice as high for Puerto Rican woman (3.44) compared with rates for non-Hispanic white women (1.84). Rates for American Indian/Alaska Native, Mexican, Asian/Pacific Islander, and Central and South American women were similar to the rate for non-Hispanic white women. In 2005, 36.5% of all infant deaths in the United States were attributed to preterm-related causes.
