[Annual trends in incidence of congenital anomalies in Tokyo metropolitan hospitals].
Annual incidence rates of selected congenital anomalies were calculated between January 1979 and December 1992 among all births in Tokyo metropolitan hospitals. Congenital anomalies were observed in 1989 infants, or about 1.5% of the 132,091 births. The characteristics of the study population were identical to that for the total births in Tokyo. Incidence rates showed practically no secular changes, indicating stationary trends during the 14 years monitored.
