Perinatal outcomes among foreign-born and US-born Chinese Americans, 1995-2000.

This paper examines nativity differences in adverse perinatal outcomes of Chinese-American mothers. Singleton live births to US-resident Chinese women (150,620 foreign-born, 15,040 US-born) and a random sample of 150,620 non-Hispanic White mothers were selected from 1995 to 2000 national linked birth/infant death certificate files. Associations between maternal nativity status and adverse perinatal outcomes were assessed using multivariable logistic regressions. Compared to US-born Chinese mothers, foreign-born Chinese mothers were less likely to be unmarried, teen mothers, have a non-Hispanic White or other race partner, be rural residents, and more likely to be less educated, or utilize prenatal care inadequately. Controlling for these factors, foreign-born Chinese-American mothers had significantly lower risks for low birth weight, preterm birth, and small-for-gestational age, whereas risks for infant mortality, neonatal mortality, and post-neonatal mortality did not differ significantly from those of infants of US-born Chinese mothers. Chinese Americans exhibited clear nativity differentials for adverse birth outcomes.
