Caesarean rate stabilises as baby boom continues
The rate of women undergoing caesarean section has stabilised for the first time in more than
ten years according to a report released today by the Australian Institute of Health and
Welfare (AIHW).
This is the first time in the last decade that the rate of caesarean section has not markedly
increased, said Associate Professor Elizabeth Sullivan of the AIHWs National Perinatal
Statistics Unit at the University of New South Wales.
According to the report, Australias mothers and babies 2007, there was only a 0.1% rise from
30.8% in 2006 to 30.9% in 2007.
New in this report is information on the rate of caesarean section for all women giving birth
by caesarean section for the first time. In 2007, the primary caesarean section rate was 21%.
This is an important measure to monitor as it is a risk factor for subsequent caesarean births,
with 83% of women who had previously give birth by caesarean section giving birth by
caesarean section in 2007, Associate Professor Sullivan said.
The rate of primary caesarean births was higher among first time mothers at 32% compared
with 10% for mothers who had previously given birth.
The report also shows more women are having babies and more are delaying having
children until later in life.
The baby boom continued with over 12,000 more births in 2007 than in 2006 and 14% more
than in 2004, she said.
The average age of women who gave birth in 2007 was 29.9 years, a year older than in 1998
and more than 14% of first-time mothers were 35 or older, compared with 9% in 1998, she
said.
About 3% of women who gave birth in 2007 received assisted reproductive technology
(ART) treatment and the average age of women who gave birth after ART was 34 years.
Of women who gave birth, three quarters had some type of analgesia administered. The
most common type of analgesia was nitrous oxide, followed by epidural or caudal analgesia.
The perinatal death rate was 10.3 per 1,000 births and fetal and neonatal deaths were 7.4 per
1,000 births and 2.9 per 1,000 live births respectively. Young maternal age, maternal
Indigenous status and multiple births were associated with higher rates of perinatal deaths.
The most common cause of perinatal death was congenital abnormality (24%) and for term
singleton babies, unexplained antepartum death (25%), congenital abnormality (17%) and
hypoxic peripartum death (14%).
