Abstract:
Objective To investigate the effect of seasonal and meteorological factors on the onset of stroke in Qinghai Plateau area.Methods Patients with stroke admitted to Qinghai Provincial People's Hospital from December 1,2011 to November 30,2016 were enrolled retrospectively.The meteorological data provided by Qinghai Meteorological Bureau were used to analyze the distribution of the number of cases in different seasons in Qinghai area and the relationship between the incidence of stroke and plateau meteorological factors.Results A total of 9 412 patients with acute ischemic stroke were enrolled,aged 15～95 years.There were significant statistical differences in the number of cases of ischemic stroke,cerebral hemorrhage,and subarachnoid hemorrhage in different seasons (all P ＜ 0.05).Among them,the number of cases with ischemic stroke increased first and then gradually decreased with the changes of spring,summer,fall and winter,while cerebral hemorrhage and subarachnoid hemorrhage showed a trend of decreasing first and then increasing gradually.There were significant differences in the number of cases in different relative humidity,temperature,and temperature differences (all P ＜ 0.05).Conclusion There are seasonal differences in the incidence of stroke in the plateau area,which may be associated with the influence of plateau meteorological factors.
