Race/Ethnic differences and age-variation in the effects of birth outcomes on infant mortality in the U.S.

By Daniel A. Powers, W. Parker Frisbie, Robert A. Hummer, Starling G. Pullum, Patricio Solis


This paper investigates the effects of birth outcomes on infant mortality for non-Hispanic white, black, and Mexican-American females in the U.S. (1995-1998). Proportional hazard models with age-varying effects of continuous birth outcome measures reveal larger birth outcome effects on neonatal mortality, smaller effects on postneonatal mortality, and moderate age-variation within the neonatal period. Unlike static models, age-varying effect models of early and late gestational age and small birth weight statistically adjust for the black neonatal mortality disadvantage relative to whites.
