Abstract
Death certificates in eastern Massachusetts after six blizzards in 1974-78, including the record blizzard of Feb. 6, 1978, were examined to identify the effect on mortality of these storms. The total number of deaths was significantly higher (8%) in a "blizzard week" than in the preceding and subsequent (control) weeks (114·1 vs. 105·3 deaths per day). Deaths from ischæmic heart-disease (I.H.D.), which rose significantly by 22% in the blizzard week from 36·7 to 44·6 deaths per day, accounted for 90% of the excess total deaths. The increase was greater in males than in females (30% vs. 12%), and in both sexes there was no difference in the distribution of deaths by age between the blizzard and control weeks. I.H.D. deaths were increased for 8 days after a snowstorm, suggesting that the effect was related to activities such as snow shovelling rather than the storm itself. The identification of those at increased risk of I.H.D. death after major snowstorms and of the circumstances surrounding such deaths could lead to public-health measures to reduce these weather- related premature deaths.
