Children born (after the 8th month of pregnancy) of mothers hospitalized for delivery from January 1961 through September 1962 at Hiroshima University affiliated hospitals were investigated. Among 153 children with congenital anomalies, there was a relatively large number (27) with more than two anomalies. A study of the effect of consanguinity between parents, blood type compatibility of the parents, atomic bomb exposure of mothers or fathers, abdominal x-ray exposure of mothers, and age of mothers showed no significant difference between children with congenital anomalies and the control children. However, primiparous women over 30 yr of age showed a somewhat higher birth rate of prematures, and the sex ratio of children born of women over 30 yr of age (whether they are primiparous or multiparous) tended to be high. It is concluded that, as epidemiological factors affecting the frequency of birth of children with external deformity, the following should be considered as important: hormone administration, drug therapy, and x irradiation before the 3rd month of pregnancy.
