MEDIA RELEASE
Results of the Mattress-Wrapping Campaign for Cot Death Prevention
Following receipt of updated cot death statistics, scientist Dr Jim Sprott has issued the statistical results of the New Zealand mattress-wrapping campaign for cot death prevention:
Start date of publicity promoting mattress-wrapping: 1995
Number of babies who have slept on wrapped mattresses: At least 165,000 (1)
Reported cot deaths among those babies: None
Cot deaths on unwrapped mattresses (or parallel bedding situations) during the same period: About 800
Reduction in New Zealand cot death rate since mattress-wrapping commenced: 68% (2)
Approximate reduction in Pakeha cot death rate: 85% (2)
These major reductions in New Zealand cot death rates cannot be attributed to the cot death prevention advice issued by the Ministry of Health. There has been no material change to that advice since 1992; and prior to the introduction of mattress-wrapping the New Zealand cot death rate had been static since 1993.
Publication of results of the New Zealand mattress-wrapping campaign: Two journals of environmental medicine (3,4)
Statistical proof that mattress-wrapping
prevents cot death:
p = less than 1.9 x 10(exp -22) (i.e.
more than one billion times the level of proof which is
usually regarded as establishing a medical proposition)

European descent.
