Research into stillbirth

When a baby dies after 24 weeks of gestation it is called a stillbirth. Around 2.6 million babies are stillborn each year. Tommy’s research is helping to change this.

In the UK, around 1 in 240 pregnancies end in stillbirth – when a baby dies in the womb after 24 weeks gestation. This is equivalent to over 3,200 babies dying every year. Our stillbirth rate is currently 24th out of 49 high income countries. Often, parents are given no reason for their loss, and are left to cope with little support. Read stories from our supporters about their experiences of stillbirth and neonatal death.

The statistics are shocking:

  • 9 babies are stillborn every day in the UK, and around 7,200 globally
  • Of the 2.6 million babies that die every year, half could be saved with improved quality of care
  • 98% of stillbirths happen in low and middle income countries
  • An estimated 4.2 million women are living with depression associated with stillbirth

We need answers, fast.

Tommy’s is carrying out vital research to find out why stillbirths happen, and how we can prevent them. Rates of stillbirth are falling – but not fast enough. Our research is helping us understand the causes of stillbirth, so we can find the babies at risk in time to help them.

Stillbirth is often linked with fetal growth restriction – where the baby stops growing normally – and a very low weight can make stillbirth four times more likely. In more than half of these cases, the placenta – the organ that gives a growing baby food and oxygen – has stopped working properly.

Our research aims to reduce stillbirth rates by finding the missing links between stillbirth, the placenta, and the baby’s growth. Most of our stillbirth research takes place in our Manchester Research Centre , where we have made great progress in our Rainbow and Placenta Clinics . Research focuses on three main areas:

  1. Understanding the causes
  2. Treatment and prevention
  3. Improving care for women at risk of, and following, a stillbirth

We are already making strides towards our goals.

Here are some of our recent achievements:

  • In St. Mary’s Hospital, we lowered the average number of stillbirths by 19% from 2012 to 2017. This is equivalent to 12 fewer babies dying every year.
  • In Edinburgh, obese women attending our antenatal clinic were an astounding 8 times less likely to have a stillbirth than women receiving standard care.
  • We have developed a new way of looking at the placenta using Magnetic Resonance Imaging (MRI). This will help doctors tell which women have healthy pregnancies and which babies may be struggling
  • The AFFIRM study is looking at whether a package of care and information for women with reduced fetal movements can lower the number of stillbirths. When a similar package was introduced in Norway, stillbirth rates fell by 30%.
