This report was based on the 280 cases of congenital anomalies among 17,821 newborns delivered after 20 weeks gestation from Jan. l, 1983 to Dec. 31, 1992. at department of Obstetrics and Gynecoloby, Yonsei University. Wonju College of Medicine.
@ES The analyesd results were as follows ;
@EN 1. The overall incidence of the congenital anomaly were 280 cases(1.57%)among 17,821 deliveries.
2. The incidence of congenital anomalies seems to be increasing year by year.
3. The incidence of congenital anomalies over 35year old group was 1.88% and that of under 24 year old group was the lowest(0.74%).
4. The incidence of the congenital anomalies according to parity was higher in the multipara groups(1.69%) that of nullipara groups(1.47%).
5. The frequence of the congenital anomalies in male baby(1.74%) was higher than that of femle baby(1.38%).
6. The incidence of low berth weight less than 2500 gm in congenital anomaly was 3.99% was 3.4 times higher than of mere than 2500gm(1.18%).
7. The incidence of congenital anomaly in the stillbirth was 19.86%, which was about 15.6 times higher than that of live birth(1.27%).
8. The incidence of the types of the congenital anomaly were 19.6%in central nervous system, 18.9% in gastrointestinal system, 8.9% in skin, 6.4%in chromosomal anomaly and multiple anomaly.
9. The incidence of perinatal death of the congenital anomalies was the highest in the highest in the CNS anomaly 65.5% and then the next incidence of multiple anomaly 55.6%, and chromosomal anomaly 33.3%, cardiopulmonary anomaly 26.5%,
gastrointesinal
system anomaly 18.9, genitourinry system anomaly 6.9%, musculoskeletal anomaly 4.2%, but none in skin .
10. Among womcn was had delivered at least one baby with congenital anomaly 6.4%of all babies were abnormal in chromosome and 46 women were exposed to adverse enviromental factors, 18 cases of women was exposed to infection, 25 cases of women
had
histories of taking various medication, especially herb drugs which took. During the first trimester of pregnancy. Those adverse enviromental factors were not direct cases of congenital anomaly, but there were some posibilities that congenital
anomaly
could be developed from pregnant women who had been exposed to adverse enviromental factors.
But 77.1% of all women had shown unkinown causesk.
