Sudden infant deaths and cold weather: was the rise in infant mortality in 1986 in England and Wales due to the weather?
Using the daily number of deaths due to sudden infant death syndrome in England and Wales from 1979 to 1985, and the daily temperature recorded at the London Weather Centre, two models were constructed, one including a temperature term and one without it, and the models used to predict the mortality in 1986. It was found that the model using temperature had a slightly better predictive power and successfully accounted for the increased mortality in February 1986. Thus, we conclude that the excess mortality of February 1986 was associated with the unusually cold weather during that month.
