To describe trends in mode of delivery, to identify significant factors which affected mode of delivery, and to describe how these factors and their impact have changed over time. ⋯ Our data show significant changes in mode of delivery in Western Australia from 1984-2003, with an increasing trend in both elective and emergency caesarean section rates that do not appear to be explained by increased risk or indication.

Randomized Controlled Trial Multicenter Study
The Control of Hypertension In Pregnancy Study pilot trial.
To determine whether 'less tight' (versus 'tight') control of nonsevere hypertension results in a difference in diastolic blood pressure (dBP) between groups. ⋯ The CHIPS pilot trial confirms the feasibility and importance of a large definitive trial to determine the effects of less tight control on serious perinatal and maternal complications.

To investigate the cause of a recent increase in hysterectomies for postpartum haemorrhage in Canada. ⋯ There has been a recent, unexplained increase in the frequency, and possibly the severity, of atonic postpartum haemorrhage in Canada.
-
To describe a 10-year trend in preterm birth. ⋯ Over the 10-year period of 1994-03, the rate of spontaneous preterm birth among low-risk women having a live singleton birth has risen in Australia.

To establish whether women's preference for elective caesarean section (ELCS) changes as gestation advances. ⋯ Many women changed from preferring ELCS to preferring VD as their pregnancy approached term. The partner's preference was a significant determinant for the women's choice. If a decrease in the proportion of women preferring ELCS is desired, the intervention programme should target the women and their partners who hold such a preference at 20 weeks.
