Influence of social class on the risk of recurrence of anencephalus and spina bifida.
This study suggests that social class has an effect on the incidence of anencephalus and spina bifida, the malformations being more frequent in the lower socio-economic groups. A family study of 226 patients with a CNS malformation suggests that social class also may be important in determining the recurrence risk of such malformations: there are higher risks in social classes III, IV and V than in social classes I and II.
