Sudden Infant Death Syndrome – Where are we now in 2016?

Posted by Mandy Tomlinson on Thu, Nov 24, 2016 @ 09:30 AM

Sudden Infant Death Syndrome (SIDS) which is also known ‘cot death,’ is the sudden, unexpected and unexplained death of a baby for no obvious reason.  Sometimes a post mortem can reveal a cause of death, but the deaths which remain unexplained after post mortem are recorded as a Sudden Infant Death.  The number of SIDS death has fallen over the past 25 years and currently there are around 247 unexplained infant deaths of babies and toddlers every year in the UK.  It still accounts for a quarter of all deaths between 1 month and 1 year of age in the UK.

Anne Diamond and the Back to Sleep Campaign

The terms cot death, sudden infant death and SIDS was recognised in the UK as a registered cause of death in 1971. From this time until 1982 there was an increasing interest and recognition of cot deaths.  The cot death rate rose to 2.1 per thousand live births in 1988. 

ann-diamond-2.jpgIn 1991, Anne Diamond, a UK TV presenter who was at the height of her fame, lost her son Sebastian to a cot death one night and she received a lot of unwanted media attention as the family grieved. As the months went on, however, Anne began researching SIDS and found that for many years, experts had recommended infants should sleep on their tummies to prevent reflux, and this was still the official advice. She then visited the Foundation for the Study of Sudden Infant Death (the Lullaby Trust) shortly after Sebastian died and found them connecting “sleep position” with cot death. Shortly after this, research was published in many countries, including the UK, which showed that putting babies to sleep on their backs was a major factor in reducing infant mortality. Anne was instrumental in setting up a working party to advise the government on research into SIDS, and from there she secured support of UK health professionals and raised funding to begin a national Back to Sleep Campaign with the National Childbirth Trust (NCT), to ensure the message got out that babies should be put to sleep on their back instead of their front.  The government launched its own campaign to reduce SIDS 2 years later in 1993.

The health campaign was extremely successful. Figures from the Lullaby Trust show in 1989 there were 1,545 SIDS cases in the UK.  In 1992, the year after the Back to Sleep campaign was launched, this figure fell to 647. That’s an incredible 58% decrease in infan cot deaths, from an extremely simple message, which cost nothing to implement except a behaviour change from health professionals to parents. Anne suffered from the media when Sebastian died from invasion of her privacy but as she was so well known the media also helped her to spread the message and drive a very successful health promotion campaign.

SIDS Risk Factors

Although there is still a lot of mystery surrounding SIDS, we do know much more than we did in 1991. Peak incidence of SIDS occurs between 1 and 3 months of age although events can occur in babies up to 12 months of age. We also now know that risk factors can be:

  • exposure to tobacco smoke (pre and postnatal)
  • prone (tummy) and side sleeping
  • bed-sharing during sleep
  • a sleeping environment which includes soft mattress or sofa, which can also increase the risk of suffocation
  • overheating by placing too many layers of clothes or bedding on a baby
  • viral infections, especially colds and congestion

SIDS Prevention

There are certain measures you can take to help protect against and prevent SIDS.These include:

  • Avoiding prenatal and postnatal smoke exposure
  • Placing an infant on their back and not on their front when sleeping
  • Ensuring a safe sleeping environment using firm mattresses with tightly fitted sheets.  Do not overwrap the baby in sheets and clothing, do not sleep with the baby in sofas and armchairs or using pillows
  • Leaving the baby’s head exposed and not covered when sleeping
  • Avoiding bed-sharing where possible, as it increases the risk with a child under three months, especially with a parent who has consumed alcohol, drugs or who smokes
  • Use of a pacifier during sleep
  • Immunisation against illnesses and infections
  • Breastfeeding, as this helps with respiratory function and quality of sleep.
