      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.

    • Key points: Smoking

      Latest available information

      Data from the NSW Population Health Survey is used to measure the NSW State Government targets on reducing smoking in the population and is comparable with other sources of information on smoking in NSW.

      • 15.2% of adults aged 16 years and over (18.1% of men and 12.3% of women) were current (daily or occasional) smokers, as estimated from the 2017 NSW Adult Population Health Survey (self-reported using Computer Assisted Telephone Interviewing or CATI).

      •  15.4% of persons aged 15 years and over (18.8% of males and 12.1% of females) in NSW were current smokers (defined as daily, at least once a week or less than weekly), as estimated from the 2014-15 Australian Health Survey (interviewer-administered questionnaire).

      • 8.3% of mothers smoked during pregnancy in 2016, as reported to the NSW Perinatal Data Collection.

      Latest available data for secondary school students in NSW

      • 6.7% of students aged 12-17 years (7.1% of boys and 6.3% of girls) were current smokers, as estimated from the 2014 NSW School Students Health Behaviours Survey (self-completed questionnaire).

      Latest available data for adult Aboriginal persons in NSW

      • 28.5% of Aboriginal adults aged 16 years and over were current smokers as estimated from the 2017 NSW Adult Population Health Survey (self-reported using CATI).

      • 41.3% of Aboriginal mothers smoked during pregnancy in 2016, as reported to the NSW Perinatal Data Collection.

      Overall trends in NSW

      Self-reported data on current smoking have been collected for adults in NSW since 1997 through the NSW Population Health Survey, since 1977-78 through the National Health Survey (from 1995), since 1985 through the National Drug Strategy Household Survey, and since 2011 through the Australian Health Survey.

      Self-reported data on current smoking have been collected for students in NSW since 1984 through the NSW School Students Health Behaviours Survey.

      Prevalence estimates, although differing slightly between surveys because of different sampling frames, participation rates and modes of collection (telephone, self-completed questionnaires, face-to-face personal interview and drop-and-collect) have all been decreasing over time.

      Hospitalisations attributable to smoking

      A total of 47,196 hospitalisations were attributed to smoking in NSW in 2014-15, which was approximately 1.5% of all hospitalisations.

      The rate of hospitalisations attributable to smoking decreased in males by almost 23% but remained stable in females in NSW between 2001-02 and 2014-15.

      The rate of hospitalisations attributable to smoking increased in both Aboriginal males and Aboriginal females in the period between 2001-02 and 2011-12. In recent years, the rates have remained stable.

      Deaths attributable to smoking

      A total of 5,460 deaths were attributed to smoking in NSW in 2013, which was approximately 11% of all deaths in 2013.

      The rate of death attributable to smoking has been declining in the decade up to 2013; the decline was much greater in males (about 32%) than in females (about 17%) but it occurred from a much higher base in males. In 2013, the rate of death attributable to smoking in males and females was 85.3 and 40.7 deaths per 100,000 population, respectively .

    • Introduction: Smoking

      Smoking and health implications

      Tobacco smoking is one of the biggest causes of premature death and is a leading preventable cause of chronic disease in New South Wales. It is a major risk factor for cardiovascular disease, a range of cancers, chronic obstructive pulmonary disease, coronary heart disease and a variety of other diseases and conditions. Approximately one in five of all cancer deaths are due to tobacco smoking.

      There is a no safe level of exposure to second-hand tobacco smoke. In adults, breathing second-hand smoke can increase the risk of heart disease, lung cancer and other lung diseases. It can worsen the effects of existing illnesses such as asthma and bronchitis. For children, inhaling second-hand smoke is even more dangerous. Children are more likely to suffer health problems due to second-hand smoke such as bronchitis, pneumonia and asthma.

      Interventions 

      Australia has one of the most comprehensive tobacco control policies and programs in the world. The aim of the tobacco control programs in NSW is to contribute to a continuing reduction of smoking prevalence rates in the community.
