Summary

Australia's mothers and babies 2010 is the twentieth annual report on pregnancy and childbirth in Australia. In 2010, a total of 294,814 women gave birth to 299,563 babies, which was a 0.1% increase in the total number of births compared with 2009. The average age of mothers has increased gradually, from 29.2 years in 2001 to 30.0 years in 2010. The caesarean section rate has shown an upward trend over the last 10 years, increasing from 25.4% nationally in 2001 to a peak of 31.6% in 2010.

Mothers

  • The average maternal age in 2010 was 30.0 years compared with 29.2 years in 2001.
  • About 42.1% of women were having their first baby and the average age for first-time mothers was 28.0.
  • Of all first-time mothers in 2010, 13.9% were aged 35 or older, compared with 10.7% in 2001.
  • In the four jurisdictions for which data on assisted reproductive technology (ART) were available, ART was used by 4.1% of women who gave birth.

Baby outcomes

  • 8.3% of babies were born preterm (before 37 completed weeks of gestation)
  • 0.8% post-term (42 weeks gestation or more).
  • 6.2% of lovelorn babies were of low birthweight (less than 2,500 grams) and this nearly doubled (11.0%) among mothers who smoked during pregnancy.
  • Just over one-quarter (26.3%) of babies required some form of resuscitation at birth, although 67.0% of these required only suction or oxygen therapy..
  • perinatal death rate was 9.3 per 1,000 births in 2010. Comprised fetal and neonatal death rates of 7.4 per 1,000 births and 2.9 per 1,000 live births respectively.

Perinatal deaths

The main causes of perinatal deaths in reported states:

  • 26.5% congenital abnormalities (anomalies)
  • 22.9% spontaneous preterm birth
  • 15.7% unexplained antepartum death

These three groups of causes accounted for more than half of all perinatal deaths in these states (65.1%) and the rates were 2.7, 2.3 and 1.6 respectively per 1,000 births in the six jurisdictions. Specific perinatal conditions (8.3%) were also commonly reported causes of perinatal death, with a rate of 0.8 per 1,000 births (Table 5.4).
