title: Obstetric outcomes in nulliparous women aged 35 and over with dichorionic twin pregnancy.
abstract: The aim of this study is to investigate maternal and neonatal outcomes in dichorionic twins to nulliparous women older than 35 compared to those of their younger counterparts. This was a retrospective study of dichorionic twin pregnancies managed at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2006. Nulliparous women 35 years and older at delivery (n = 60) were compared with nulliparous women between the ages of 20 and 29 at delivery (n = 71). The women > or = 35 year old were more likely to have used assisted reproductive technology. There were no measurable differences in obstetric outcomes such as preeclampsia, premature delivery, low birth weight and neonatal asphyxia between the two pregnancies. Advanced maternal age does not seem to affect obstetric outcomes in nulliparous dichorionic twin pregnancies.
