Multiple gestations are associated with an increased risk of maternal morbidity and mortality independent of maternal age. Previous reports by the Canadian Institute for Health Information established the overall association between advanced maternal age and complications related to pregnancy and childbirth. This article takes a more focused look at the association between advanced maternal age and maternal outcomes in multiple gestation pregnancies. We found, for mothers aged 35 years and older carrying multiples--after adjusting for mothers' parity, neighbourhood income and residence (rural/urban)--an increased risk of pregnancy complications including pre-existing hypertension, gestational hypertension, pre-eclampsia/eclampsia, gestational diabetes and placenta previa and an increased risk for Caesarean delivery.
