| Abstract | The frequency with which congenital malformations occur varies considerably from country to country and, within countries, from area to area and social class to social class. For example, neural-tube malformations are five times commoner in England and Wales than in Japanl and nearly three times commoner in the coalmining valleys of South Wales than along its coastal plain2: in Scotland they are three times commoner in infants born into social class v than in infants born into social classes I and II.1 From these and similar observations it has been inferred that environmental teratogens must be at work, but in making such an inference few research workers stop to consider what relation, if any, the prevalence of malformations at birth bears to their incidence at the time they are laid down-early in the first trimester of pregnancy. |
