Studies suggest that certain interracial couples, particularly those involving Black partners, face increased risks for adverse birth outcomes, including prematurity, low birth weight, and stillbirth. These outcomes are associated with higher miscarriage rates.
>Fertility is generally lower among racially exogamous than endogamous unions, especially among Asian American-White couples. Fertility among American Indian-White couples is much closer to patterns of White couples than of American Indian couples. Fertility among other interracial couples nevertheless varies by the race of male partners. That is, fertility of the Black male/White female and the Hispanic male/White female couples is similar to patterns found among endogamous Black and Hispanic couples, respectively. The White male/Black female and the White male/Hispanic female couples follow the fertility patterns of White couples.
