Stillbirth Facts

Stillbirth, the birth of a baby without signs of life after 20 weeks’ gestation, is a tragedy for parents and families and a major unaddressed public health problem.

Stillbirth has enormous psychosocial impact on parents and care providers, and wide-ranging economic impact on health systems and society at large (Heazell 2016). In The Lancet 2016 Ending Preventable Stillbirths series we emphasise that the poor global response to stillbirth has been a persistent injustice to families and communities.

As stated by Richard Horton, Editor in Chief of The Lancet,

“Not all global health issues are truly global, but the neglected epidemic of stillbirths is one such urgent concern”.

What is stillbirth?

  • In Australia, stillbirth is defined as the birth of a baby without signs of life after 20 weeks’ gestation.

How frequent is stillbirth?

  • The rate of stillbirth in Australia is 7.4 per 1000 births, which equals approximately 2,200 families each year.
  • One in every 137 women who reach 20 weeks’ gestation will have a stillborn child.
  • For Indigenous women and women from other disadvantaged groups, this risk is often doubled (Flenady 2016). 

How does stillbirth affect parents and families?

  • Parents who have had a stillborn baby face an increased risk of anxiety, depression, post-traumatic stress, and suicidal ideation (Heazell 2016).
  • Stigma around stillbirth intensifies parents’ distress and often makes them feel more isolated in their grief. Our research has shown that up to 50% of bereaved parents in Australia and New Zealand feel unable to talk about their stillborn baby because it makes people feel uncomfortable.
  • Many parents feel the death of their baby is not recognised as the same as the death of an older child (Flenady 2016). 

Are stillbirth rates improving?

  • There has been no improvement in overall stillbirth rates for over 20 years.
  • Some declines have been seen in stillbirth rates after 28 weeks’ gestation, but Australia continues to lag behind other developed countries.
  • Australia’s stillbirth rate after 28 weeks’ gestation is 30% higher than that of the best performing countries, such as Finland, Denmark, and Netherlands (Flenady 2016).

What are the causes of stillbirth?

  • The major causes of stillbirth in Australia are infection, maternal conditions, haemorrhage, spontaneous preterm birth, and congenital abnormality (Hilder 2014).
  • Around 25% of stillbirths remain unexplained (up to half of stillbirths occurring near full-term). The lack of a diagnosis adds to parents’ distress, as they struggle to understand “what went wrong” and “will it happen again” in a subsequent pregnancy.
  • Many stillbirths are not adequately investigated, resulting in possible missed diagnoses.
  • In 20-30% of stillbirths, the quality of care provided is a contributing factor to the death (De Rue 2000). National perinatal mortality audit programs can reduce these deaths. Without such a program in Australia, opportunities for prevention are often lost.

What are the risk factors for stillbirth?

  • Risk factors include decreased fetal movements, fetal growth restriction, smoking, hypertension, diabetes, obesity, pregnancy beyond 41 weeks’ gestation, primiparity, maternal age over 35 years (particularly for women aged 40 years or more), and previous stillbirth (Flenady 2011).
  • Indigenous and other disadvantaged groups often have constellations of risk factors (e.g. obesity, smoking, substance use, inadequate nutrition), and poor antenatal care attendance (Flenady 2016).
  • South Asian women also have higher rates of stillbirth and the reasons for this remain unclear (Davies-Tuck 2017).
  • Women who go to sleep in the supine position (lying on their back) also have an increased risk of stillbirth in late-pregnancy (McCowan 2016).
