Effect of Climatological Variables on the Frequency of Incident Stroke Hospitalization During Winter.

Introduction: Stroke data were obtained as SMR01 (157,639 incident stroke hospitalization in Scotland between 1986-2005). Method: To observe variation in weather parameter, with first stroke incidences per day, during winter, daily mean temperature/ total rainfall/average daily atmospheric pressure was compared with frequency of incident strokes per day using ANOVA (Analysis of Variance). Result: The analysis reveals an inverse statistically signifi cant relationship for average daily temperature whereas total daily rainfall and average daily atmosphere pressure exhibit borderline significance. Conclusion: Correlations of low temperature with stroke might be due to concurrent infection of respiratory system.
