摘要
目的探讨老年肺部感染发生的季节性特征。方法应用圆形分布法,对2003～2012年1584例老年肺部感染患者的发病时间进行统计分析。结果肺部感染发生高峰时间存在季节性集中趋势(r=0.0989,P<0.01),理论高峰日为12月14日,按季节应为冬季。结论老年肺部感染存在季节性集中趋势,了解其发生规律,对于指导预防工作,降低其发病率具有重要意义。
Objective To investigate the seasonal characteristics of pulmonary infection in the elderly patients.Methods The occurrence time of 1584 elderly patients was analyzed by circular distribution method from 2003 to 2012.Results The rush hour of pulmonary infection has seasonal trend(r=0.0989,P<0.01).Theoretical peak day was December 14.Theoretical peak season was winter.Conclusions The occurrence of pulmonary infection has seasonal trend.It is important to understand the occurrence regularity to guide the prevention work and reduce the incidence of the disease.
