Abstract:
Objective To study the relationship between climatic factors and cerebral hemorrhagic disease.Methods A total of 1125 cerebral hemorrhage patients were included in this study.The relationship between the onset time of cerebral hemorrhage and daily climatice factors (including temperature,humidity,atmospheric pressure,wind direction and rainfall volume) was analyzed and the onset time of cerebral hemorrhage in each patient was analyzed according to the X2 test for goodness of fit.Results The number of male cerebral hemorrhagy patients was greater than that of female cerebral hemorrhage patients.The mean age of femalc cerebral hemorrhage patients was older than that of male cerebral hemorrhage patients (P＜0.01).The incidence of cerebral hemorrhage accounted for 11％ in January in a greatest number of such patients,accounted for 5.0％ in September in a smallest number of such paticnts,and was the highest at h 4-8 AM and at h 16-20 FM in ≤45 years old cerebral hemorrhage patients.Univariate correlation analysis showed that cerebral hemorrhage was negatively related with daily mean temperature,daily mean maximal and minimal temperature (r=-0.157,r =-0.163,r=-0.156,P＜0.05),positively related with daily mean atmospheric pressure (r=0.157,P＜0.05).Multivariate linear stepwise analysis showed that cerebral hemorrhage was related with daily mean temperature,maximal and minimal temperature,and daily mean atmospheric pressure (P＜0.05,P＜0.01).Conclusion The incidence of cerebral hemorrhage differs in seasons and months,is higher in winter and lower in summer,and is thus related with temperature,atmospheric pressure and wind direction.
