试用圆形分布分析骨折病例入院时间的季节性

Analysis on Seasonality of the Time of Fracture Patients Admitted to Hospital by Circular Distribution Method

目的探讨骨折发生的季节性特征。方法应用圆形分布法对2005年-2010年3384例骨折病人的发生时间进行统计分析。结果骨折发生高峰时间存在季节性集中趋势(r=0.0843,P<0.01),理论高峰日为8月13日,按季节应为夏末秋初。结论骨折的发生存在季节性集中趋势。

Objective To investigate seasonal characteristics of fracture.Methods Statistically analyzing the occurrence time of 3384 cases of fracture patient by circular distribution method from 2005 to 2010.Results The rush hour of bone fractures has seasonal trend（r=0.0843,P0.01）.Theoretical peak day is August 13.Theoretical peak season is late summer or early autumn.Conclusion The occurrence of fractures has seasonal trend.
