Time distribution of occurrence of hypertensive brain hemohage in Jiamusi

目的：脑出血发病的时间分布。方法：病例系1997-01～2000-12我院收治的佳木斯地区的脑出血患者624例，采用圆形分布理论，统计分析脑出血的发生和时间分布的关系。结果：(1)脑出血发病人数日发病时间分布存在显著性差异(P<0.01)。(2)脑出血发病人数的月分布有显著性差异(P<0.01)。结论：脑出血发病是有节律的。

Objective:To study time distribution of occurrence of hypertensive brain hemohage(HBH). Methods: 624 cases with HBH in 1997-2000 from our hospital were analyzed with circular distribution theory.We analyzed ralationship between time distribution and occurrence of HBH. Results: The study on HBH indicated that month-by-month occurrence frequency showed significant difference(P<0.01) and The study on HBH indicated that hour-by-hour occurrence frequency showed significant difference(P<0.01) Conclusion:HBH is systematic way of occuring.
