In order to understand the occurrence of congenital malformations in our region, detailed statistics and analysis were conducted on obstetric obstetrics from January 1992 to January 1997 in February. The results showed that the incidence of congenital malformations in this region was 2.07%, which was higher than the national level of 1.3%, with the highest incidence of neural tube defects. The incidence of congenital malformations in rural areas is higher than that of urban ones. The incidence of malformations in multiple pregnancies is higher than that of one-time pregnancies.
