Outcome of twin pregnancies in North Jordan.

In a retrospective study we examined the outcome of twins delivered at Princess Badee'a Teaching Hospital from 1 January 1996 to 30 June 1999. The incidence of twin pregnancy was 1/86 with a gross perinatal mortality rate of 178 per 1000. Breech presentation was associated with the highest perinatal mortality rate (278 per 1000). One hundred and eighty-four out of the 386 twin pregnancies were preterm with the highest perinatal mortality rate (184 per 1000). The neonatal Mortality rate fell with increasing birthweight from 532 per 1000 at 1500 g to 16 per 1000 at 2500 g. Our results showed that the risk factors were mainly prematurity, low birthweight, pregnancy-induced hypertension, lack of proper antenatal care, birth asphyxia, and malpresentation.
