Notes on the data: Mothers and babies

Women who reported smoking during a pregnancy, 2012 to 2014


Policy context:  Maternal smoking during pregnancy results in higher risks of adverse outcomes for the baby before and after delivery, such as premature birth, miscarriage and perinatal death, poor intra-uterine growth and SIDS (Sudden Infant Death Syndrome). These problems may affect children through to adulthood, including a higher risk of disability and developmental delay, decreased lung function and increased respiratory illness. In 2006, smoking during pregnancy was more prevalent and heavier among Aboriginal women, with 54% smoking at the first antenatal visit compared with 17% of non-Aboriginal women in South Australia [1].

Notes:  The data previously published were for non-Indigenous women who smoked during their pregnancy. The data shown here now include all women who smoked during their pregnancy.

As these data were collected from each State and Territory health agency, they may exclude people who live in one State/Territory and used a service in another. Hence, the Australian total excludes a small number of pregnancies that were recorded in a different State/ Territory as their usual residence. All ACT published figures are of non-Indigenous people. As such the Australian total will only include non-Indigenous people for ACT.

Please note that the data may include women who were pregnant more than once during the time period.
