  • + Notes

    Definitions:

    1.1 Spontaneous vaginal birth: The number of selected primipara who have a spontaneous vaginal birth as a percentage of the total number of selected primipara who give birth.

    1.2 Induction of labour: The number of selected primipara who undergo induction of labour as a percentage of the total number of selected primipara who give birth.

    1.3 Instrumental vaginal birth: The number of selected primipara who undergo an instrumental vaginal birth as a percentage of the total number of selected primipara who give birth.

    1.4 Caesarean section: The number of selected primipara undergoing caesarean section birth as a percentage of the total number of selected primipara who give birth.

    Selected primipara is a woman 20-34 years of age at the time of giving birth, giving birth for the first time at greater than 20 weeks gestation; singleton pregnancy; cephalic presentation; and at 370 to 410 weeks gestation ('0' means zero days). 

    Data include all mothers who gave birth (stillbirth or live birth) in NSW regardless of place of permanent residence.

    Types add up to more than 100% because induction of labour can precede an instrumental vaginal birth and a birth by caesarian section.

      Recent trends

      In 2016 there were 98,727 births to 97,306 mothers in NSW, a decrease of 0.8% from 99,510 births in 2012.  The percentage of multiple (twin and triplet) pregnancies has remained fairly stable over recent years at about 1.4%.

      Between 2012 and 2016:   

      • The proportion of mothers who were teenagers continued to fall, from 3.2% in 2012 to 2.2% in 2016.

      • The proportion of births to mothers over 35 years of age has remained stable.

      • The proportion of mothers who smoked at all during pregnancy fell from 10.4% in 2012 to 8.3% in 2016.

      • The proportion of babies with low birth weight remained stable over the period, ranging from 6.1% to 6.6%.

      • The proportion of preterm births was 7.3% of all births in 2016, a decrease from 7.6% in 2012.

      • The perinatal mortality rate was 7.5 per 1,000 births in 2016, decreasing from 8.3 per 1,000 births in 2012. 

      • In 2016, there were 260 infant deaths in NSW, which was 2.7 deaths per 1,000 live births. The infant mortality rate in Australia was 3.1 deaths per 1,000 live births in 2016.

      Aboriginal and Torres Strait Islander mothers and babies

      • Between 2012 and 2016, the number of reported births to Aboriginal or Torres Strait Islander mothers increased from 3,399 to 4,174, representing 3.4% and 4.2% respectively of all babies born in NSW.

      •Between 2012 and 2016, the percentage of Aboriginal or Torres Strait Islander mothers who were teenagers fell substantially from 18.6% in 2012 to 12.8% in 2016.

      •Between 2012 and 2016, the percentage of Aboriginal or Torres Strait Islander mothers who commenced antenatal care before 14 weeks of pregnancy increased from 51.0% to 64.6%.  

      • The proportion of Aboriginal or Torres Strait Islander mothers smoking in pregnancy was 41.3% in 2016 compared with 49.9% in 2012.

      • The perinatal mortality rate among babies born to Aboriginal or Torres Strait Islander mothers was 12.2 per 1,000 in 2016, higher than the rate of 7.3 per 1,000 for babies born to non-Aboriginal or Torres Strait Islander mothers.

    • Introduction: Pregnancy and the newborn period

      Demography

      The health of Australian mothers and babies is generally good by world standards. Maternal deaths are rare, and perinatal mortality rates are low.

      The average woman in NSW can currently expect to give birth to 1.9 babies in her lifetime.

      NSW mothers are getting older with the mean maternal age at first birth around 29 years and at subsequent birth just over 30. The proportion of teenage mothers is declining.

      Burden of disease and social and economic disadvantage 

      Aboriginal mothers and babies, those from socioeconomically disadvantaged areas, and some overseas-born mothers and their babies continue to experience worse outcomes than other NSW mothers and babies.

    • Interventions: Pregnancy and the newborn period

      The NSW Ministry of Health maintains two population-based surveillance systems that collect information concerning pregnancy and birth: the NSW Perinatal Data Collection and the NSW Register of Congenital Conditions. They assist in monitoring the health of mothers and babies and, maternity service planning in NSW.

      The implementation of the NSW Aboriginal Maternal and Infant Health Strategy has improved access to culturally appropriate maternity services for Aboriginal mothers.

      The NSW Maternal and Perinatal Mortality Review Committee reviews each death of a mother or newborn baby to assess the cause and identify any possible avoidable factors. This information is used to improve services for mothers and babies.
