Premature birth: how to stop women from going into labour too soon
This research was completed on 21 April 2017
Over 60,000 babies are born prematurely every year in the UK.1-4 Tragically, premature birth is the biggest killer of babies in the UK, with nearly 1,400 babies dying each year after being born too soon.5-7 Many others who survive a very early birth develop lifelong disabilities. Despite these dangers, little is known about why some women go into labour too soon or how to stop it. Professors Nick Europe-Finner and Michael Taggart, of Newcastle University, are leading a team of expert researchers who are searching for answers. Their ultimate aim is to prevent premature birth, and save babies from death and disability.
How are babies’ lives affected now?
“Premature birth is a major cause of death and illness in babies in both the UK and worldwide,” explains Professor Europe-Finner.8 “Preterm birth rates are increasing in almost all countries.8 About 15 million babies around the world are born too soon every year – that’s more than one in 10 of all babies.8 Sadly, around one million of these babies die within just a month of being born.”8
All newborn babies are vulnerable, but those born early are particularly so. They can face difficulties with breathing, feeding and fighting infections, and are at increased risk of developing lifelong conditions such as cerebral palsy, blindness, hearing loss, lung disease and learning difficulties. They might also have an increased susceptibility to health problems during adulthood, including high blood pressure and diabetes.
Premature birth kills one baby every 30 seconds.9 More children die as a result of being born too soon than from AIDS, malaria or diarrhoea.9 We must do more to stop this.
How could this research help?
Many premature births happen when women go into labour too soon – often for no apparent reason. The research team aims to boost understanding of why this happens and find a way to stop it.
“The womb behaves very differently during pregnancy and childbirth,” says Professor Taggart. “We are investigating the natural processes that control whether the womb is relaxed, as during pregnancy, or contracting, as during childbirth. We have recently discovered that a protein called heat shock protein 20 – or Hsp20 – may have an important part to play, so we are finding out more about how this works. We are also studying whether substances that mimic Hsp20 could be used as drugs – to prevent contractions and stop babies from being born too soon.”
Premature birth can have a huge impact on the lives of babies and their families – and on society and the health system. It is essential to find ways to stop it.

Preterm birth, defined as childbirth occurring at less than 37 completed weeks or 259 days of gestation http://www.who.int/bulletin/volumes/88/1/08-062554/en/
Calculation made by Action Medical Research based on figures in references 1-4 for the total number of live births a year in the UK and the percentage of all preterm live births in England and Wales, respectively. Estimate assumes incidence of premature live birth is the same for the UK overall as it is for England and Wales.
Total no. of live births in UK = 723,913 + 25,273 + 58,590 = 807,776.
Estimated number of premature live births in UK = 807,776 x 7.7% = 62,199.
