Mortality from congenital malformations by mother's country of birth.

Mortality from congenital malformations by mother's country of birth was examined in England and Wales between the years 1976 and 1980, based on stillbirths and infant deaths. There were 18 870 stillbirths and infant deaths attributed to congenital malformations in this period, of which 2 375 (13%) were to mothers born outside the United Kingdom. There were excess deaths from malformations among Pakistani, Indian/Bangladeshi, African, and Irish mothers. In contrast, West Indian mothers had a consistent deficit in deaths from malformations over the study period. The significance of these findings is discussed.
