Namavar Jahromi et al. the rate of neonatal deaths with increasing the fetal numbers are predictably observed in the singleton and twin groups, but not in the triplets. Six of singleton neonates (3%) died in comparison to 4/42 (9.52%) of twins but none of the triplet babies died in this study, which may be contributed to the small sample size. Birth defects were reported to be associated with preterm birth and low birth weight.22 Five neonates (2.5%) from the singleton group had congenital anomalies which is consistent with the rate of con- genital anomalies in the normal population to be 3%. However, 15.7% of twins and 35% of triplets had congenital malformations. This study confirms the previous reports that the incidence of congenital anomalies is appreciably increased in twin and higher order multiple gestations compared with singletons.21 References Development of preterm regular uterine contrac- tions even in the absence of cervical changes should be considered as a potent risk factor for PTB. The most frequently associated maternal risk factors in this study were history of abortion, infertility and previous PTB, and the most frequently associated complications were preterm ROM, vaginal bleeding and febrile diseases.
