[目的]探讨急性脑血管疾病发病时间的季节性特点,为疾病的预防和医院相关科室合理配置医疗资源提供参考。[方法]收集某医院神经内科病房2007年7月至2010年6月收治的急性脑梗死患者和急性脑出血患者的发病时间资料,运用圆形分布法分析其发病时间的聚集性。[结果]经圆形分布分析,两种疾病的发病均存在季节性集中趋势(P<0.01),急性脑梗死的高发期为秋冬交替季节,急性脑出血好发于隆冬季节;两者的发病季节集中趋势相对较弱,高峰期跨度均接近8个月。[结论]急性脑梗死和急性脑出血的发病有一定的季节集中趋势,但相对较弱。
[Objective] To investigate the seasonal characteristics of the onset time of acute cerebrovascular disease and provide reference for the prevention of diseases and rational allocation of medical resources to relevant departments of the hospital. [Methods] The data of onset time of patients with acute cerebral infarction and acute cerebral hemorrhage admitted from July 2007 to June 2010 in a hospital neurology ward were collected. The roundness distribution was used to analyze the time of onset of aggregation. [Results] The results of circular distribution showed that there was a seasonal concentration trend in both diseases (P <0.01). The high incidence of acute cerebral infarction was alternation between autumn and winter, and acute cerebral hemorrhage occurred in winter. The onset of both The seasonally concentrated trend is relatively weaker, with peak periods spanning nearly eight months. [Conclusion] The incidence of acute cerebral infarction and acute intracerebral hemorrhage have a certain seasonal concentration trend, but relatively weak.
