The perinatal outcome of twin births in Australia is
described from 1973 to 1980. Over that period, the
perinatal mortality rate declined more slowly in twins
than singletons. The stillbirth rate actually increased
in twins due to a rise in antepartum deaths. An
increasing proportion of monozygotic twins may have
contributed to this trend. The overall perinatal
mortality rate was 82.85/1,000 for twins and 16.49/1,000
for singletons, giving a relative risk of 5.0.
