Women who have previously had a caesarean section are at slightly increased risk of stillbirth, according to a large UK study.
Researchers at Oxford University looked at 81,784 deliveries between 1968 and 1989. They found the risk of stillbirth for women exposed to previous caesarean section was 4.6 per 1,000, compared with 3.5 per 1,000 for those who had not.
Study author Ron Gray, from the National Perinatal Epidemiology Unit, said: 'This is now the fourth study of this kind to have shown an increased risk.
'Pregnant women and clinicians need to be aware of the potential increased risk, but should also be aware that the risk to any particular pregnancy is very small,' Dr Gray said.
