White denotes infants whose mother was white. Non-white denotes infants whose mother was Black, Asian, Hispanic, Native American, or Other. For categorical variables, p-values correspond to the significance of the omnibus Wald test for the entire variable, not a specific category. Model also adjusts for immigration status, initiation of prenatal care after the 1st trimester, and maternal diabetes. * OR: adjusted odds ratio. n/a: not applicable. †Years of education completed.
