Abstract

In this study, Sara Polcaro-Pichet sought to determine whether cold temperatures and snowfall were independently associated with stroke-related deaths and whether the impacts differed between hemorrhagic and ischemic strokes. Based on a comparative analysis of over 13 000 stroke-related deaths and meteorological data for Québec between the months of November and April, the findings indicate that cold temperatures and snowfall are independent risk factors with regard to hemorrhagic stroke in men. The results therefore imply that interventions to prevent fatal hemorrhagic strokes in men must also consider their exposure to cold temperatures and snowfall.
