The SIDS rate was highest for children of mothers aged under 20 at the time of the child's birth. SIDS are more common among boys than girls. Most SIDS occur during winter. Between 1994-1998, there were 36 per cent more SIDS in the three month period January to March compared with the three month period July to September. But with six babies still dying every single week, there remains much to be done.
Cot death is still the main cause of death in babies over one month old.
In 1971, when records of SIDS first started, there were 1,600 deaths a year. Cot deaths fell massively in 1997 after research from New Zealand found that babies were much safer sleeping on their backs. Other studies have shown links between smoking during pregnancy and in the same room as babies, overheating and keeping the baby's head uncovered. However we are determined to reduce the rates of SIDS still further. We will continue the campaign to advise families on ways in which these tragedies can be avoided and we will shortly be issuing a further series of our leaflet, Reduce the Risk of Cot Death.
