Older mothers do not confer greater perinatal risk to dichorionic diamniotic twins.

Advanced maternal age may be associated with adverse maternal and perinatal outcomes in singleton pregnancies. It is unclear whether a similar association exists for dichorionic twins. This objective of this study was to ascertain whether advanced maternal age was associated with increased perinatal morbidity and mortality in a 15 year retrospective review of dichorionic diamniotic (DCDA) twins delivered at Queen Charlotte's and Chelsea Hospital, a tertiary referral center in London, UK, between 1994 and 2008. In all, 1 174 DCDA deliveries occurred in the study period. Maternal age was not associated with neonatal unit admission or composite fetal and neonatal mortality. Advanced maternal age appeared to have no deleterious effect on the perinatal outcomes of DCDA twin pregnancies.
