We examine differences in the mean birth weights of infants born to non-Hispanic black, non-Hispanic white, and Mexican-origin Hispanic mothers (of any race) in Chicago in 1990 using linear regression models with neighborhood fixed effects. Our pooled models accounted for 64% of the black-white difference and 57% of the black/Mexican-origin Hispanic difference. Differences in the relationship between measured characteristics and birth weight accounted for around half the birth-weight gap between non-Hispanic black and other infants. Efforts to close this gap must go beyond programs that aim to reduce the level of risk factors among black women to address the causes of differences in the effects of risk factors.
我们使用具有邻里固定效应的线性回归模型，研究了1990年在芝加哥出生的非西班牙裔黑人、非西班牙裔白人以及墨西哥裔西班牙裔母亲（任何种族）所生婴儿的平均出生体重差异。我们的汇总模型解释了黑人和白人之间差异的64%以及黑人和墨西哥裔西班牙裔之间差异的57%。测量特征与出生体重之间关系的差异约占非西班牙裔黑人和其他婴儿出生体重差距的一半。缩小这一差距的努力必须超越旨在降低黑人女性风险因素水平的项目，以解决风险因素影响差异的原因。
