Outcome of pregnancies progressing beyond 28 weeks gestation in women with a history of recurrent miscarriage

Ninety-seven women who had had three or more miscarriages had also had at least one pregnancy with a singleton birth that had reached 28 weeks gestation. Information was available on these 118 babies: 30% were small-for-gestational age (birthweight less than or equal to 10th centile using figures from Scotland 1973-79), 28% were born preterm, and the perinatal mortality rate (excluding babies of less than 28 weeks gestation) was 161/1000 births, all of which are significantly increased above the prevalence for a normal obstetric population. These observations may serve to alert the clinician to the increased risk of these complications when dealing with women who have a history of recurrent miscarriage.
