【摘要】 目的　探讨自发性脑出血患者发病时间变化的规律性。方法　采用回顾性调查方法对脑出血发病进行昼夜时间和月变化的规律分析。将 2 4h分为 12个时段 ,按 1年 12个月份进行分析。结果　 (1)一昼夜各发病时间段之间脑出血发病人数有显著性差异 (χ2 =6 3.799,P <0 .0 0 1) ,呈双峰分布 ,7～ 8am、5～ 6pm为 2个发病高峰 ,午后 1～ 2 pm为发病低谷 ;不同月份间脑出血发病人数有显著性差异 (r =0 .732 ,P <0 .0 5 ) ,呈冬季高夏季低分布 ;(2 )男、女脑出血 12时段内发病人数均有显著性差异 (男 χ2 =39.310 ,P <0 .0 0 1,女 χ2 =6 8.36 9,P <0 .0 0 1) ;男女脑出血月份间发病人数均有显著性差异 (男r =0 .6 2 7,P <0 .0 5 ,女r=0 .96 6 ,P <0 .0 5 )。结论　脑出血发病与昼夜时间有关 ,呈双峰分布 ;脑出血发病与月份气候变化有关 ,有冬季发病的集中趋势。更多还原

【Abstract】 Objective To explore the pattern of diurnal and monthly variations in the onset of spontaneous intracerebral hemorrhage.Methods A retrospective study was conducted in which the time of onset of SICH was divided into 12 periods (2-hour intervals and 12-month of every year).Results There were clear differences of the number of SICH patients in diurnal variation (χ2= 63.799,P< 0.001) and in monthly (r= 0.732,P< 0.05). On the diurnal variation curve, two peaks (7～8 am and 5～6 pm) and a trough (1 pm～2 pm) could be observed. On the monthly variation curve of the whole patients, a peak in vinter and trough in summer could be observed, while obvious significance in male and in female respectively (male r= 0.627, P< 0.05, female r= 0.966, P< 0.05).Conclusion There were diurnal and monthly variations of the onset of SICH. Two peaks and a trough could be observed on the diurnal variation curve and the monthly variation curve focus on winter.更多还原
