Sleep On Side - a pregnancy campaign
Tommy's has launched the Sleep On Side campaign today in response to the publication of a fourth research study that confirms that the risk of stillbirth is doubled if women go to sleep on their backs in the third trimester.
The Midlands and North of England Stillbirth Study (MiNESS), was published in BJOG: An International Journal of Obstetrics and Gynaecology. It is the largest study of maternal sleep position and risk of stillbirth. The study was funded by Action Medical Research, Cure Kids, Sands and Tommy’s.
The increased risk associated with women going to sleep on their back has now been demonstrated consistently by four studies in women of different ethnicities and in different countries.
If all pregnant women in the UK went to sleep on their side in the third trimester, MiNESS estimates a 3.7% decrease in stillbirth, saving around 130 babies’ lives a year.
The advice to pregnant women is to go to sleep on their side for any episode of sleep in the third trimester, including:
- going to sleep at night
- returning to sleep after any night wakenings
- day time naps
As the going-to-sleep position is the one held longest during the night, women should not be concerned if they wake up on their back, but should simply roll back onto their side.
The MiNESS study did not find a difference in risk between sleeping on the right or left side. One of the previous studies did show that sleeping on the right increased the risk, but as this was not found in the other three studies, the Tommy’s campaign recommends that women can go to sleep on either side.
Professor Heazell says:
“Around 9 babies are stillborn every day in the UK. Stillbirth is devastating, with long-lasting effects on bereaved parents. Parents want to know why their baby has died, whether it might happen again if they try for another baby and what they can do to avoid further stillbirth.”
At the Tommy’s Stillbirth Research Centre, we work to identify what we call ‘modifiable risk factors’ for stillbirth. These risk factors are things in day-to-day life that increase expectant mothers’ chances of having a stillborn baby that, importantly, the women have the power to alter, either alone or with medical help.”
We believe that identifying, and avoiding, risk factors that are strongly associated with stillbirth will reduce the number of babies who are stillborn. The MiNESS results have implications as they indicate that if women go to sleep on their side in late pregnancy rather than on their back there could be 3.7% reduction in stillbirth.”
The four charities, Action Medical Research, Curekids, Sands and Tommy’s, who funded the research have put out a joint statement:
“This research and campaign was only made possible with funding from our four charities, which are supported by parents who have experienced stillbirth. We hope that this information will help parents and reduce the number of babies who are stillborn each day”
Mr Edward Morris, Vice President for Clinical Quality at the Royal College of Obstetricians and Gynaecologists, said:
“This is an important study which adds to the growing body of evidence that sleep position in late pregnancy is a modifiable risk factor for stillbirth. This new research is extremely welcome as a significant number of stillbirths remain unexplained, particularly those in late pregnancy. The impact of stillbirth on parents and professionals is devastating and the RCOG is committed to working collaboratively on research, audit and training for healthcare professionals in order to achieve a substantial reduction in the UK stillbirth rate.”
Louise Silverton, Director for Midwifery at the Royal College of Midwives, said:
“Stillbirth is a terrible tragedy for mothers and their families and we must do all we can to bring stillbirth rates down.
This addition to current knowledge is very welcome. The Tommy’s campaign and the research findings are a great example of how through making small changes we can begin to bring down stillbirth rates. It is a simple change that can make a difference and it will be important to ensure that this is communicated effectively to women.”
Tips for going to sleep on your side in the last three months of pregnancy
- Put a pillow or pillows behind your back to encourage side-sleeping.
- If you wake during the night, check your position and go back to sleep on your side.
- Pay the same attention to sleep position during the day as you would during the night.
