The results confirmed the teratogenic effect of Anti-HBs. The monofactorial analysis showed that the newborn congenital malformationincidence in Anti-HBs positive mothers was higher than that in Anti-HBs negative mothers (x2=6. 0274,P = 0.0141). The multifactorial analysis by using unconditional Logistic Repression model confirmed that Anti-HBs had a teratogenic effect (OR=5. 30952, P=0. 000302). The possibleteratogenic mechanism of Anti-HBs is discussed. It is important to further study the teratogenic effect of Anti-HBs in eugenics. Anti-HBc may have prevention effect on congenital malformation development (OR= 0. 27110, P= 0. 004515). In addition, exposure to toxicants during pregnancy is one of the risk factors causing congenital malformation (OR= 8. 17080, P=0. 001780).展开更多
