A retrospective study of 21,442 Singaporean women who gave birth at th
e National University Hospital, Singapore, between January 1986 and No
vember 1991 is used to assess the effects of increasing age on obstetr
ic performance. The results show that reproduction after the age of 35
years in Singapore is associated with a higher incidence of antenatal
complications such as hypertension and diabetes and a higher rate of
obstetric intervention. However, given the current level of obstetric
and neonatal care in Singapore, these adverse features do not prejudic
e the obstetric and neonatal outcomes.
