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。
Objective To investigate the regularity of the onset time of patients with spontaneous cerebral hemorrhage. Methods A retrospective investigation of cerebral hemorrhage incidence of diurnal time and monthly changes in the law. Divide 24 hours into 12 periods and analyze them according to 1 year and 12 months. Results (1) There was a significant difference in the number of cerebral hemorrhage between the onset of the day and the night (χ2 = 6 3.799, P <0.001), showing a bimodal distribution, with incidences of 7 to 8 years and 5 to 6 months The peak was in the afternoon 1-2 pm, and the incidence of cerebral hemorrhage in different months was significantly different (r = 0.7232, P <0.05), which was high in winter and low in summer; (2) The incidence of intracerebral hemorrhage within 12 hours had significant difference (male χ2 = 39.310, P <0.001, female χ2 = 6 8.36 9, P <0.01) There were significant differences (male r = 0.62 7, P <0.05, female r = 0.96 6, P <0.05). Conclusions The incidence of cerebral hemorrhage is related to the time of day and night. The incidence of cerebral hemorrhage is bimodal. The incidence of cerebral hemorrhage is related to the monthly climate change, and there is a concentrated tendency of winter onset.
