6186例脑卒中患者发病时间的季节性分析

目的探讨青岛市区脑出血(CH)、脑梗死(CI)、蛛网膜下腔出血(SAH)发病时间的季节规律。方法收集青岛市1998年～2002年脑卒中患者6186例,其中CH1179人,CI4821人,SAH186人。圆分布分析探讨脑卒中患者发病时间的季节规律。结果CH冬季高发,平均角在1月份(P<0.05),男性患者的平均角在2月份(P<0.05),女性患者的平均角在1月份(P<0.05);CI秋季高发,男、女间无差别,平均角在10月份(P<0.05);SAH秋季高发,平均角在10月份(P<0.05),男性患者的平均角在9月份(P<0.05),女性患者的平均角在10月份(P<0.05)。结论青岛市的脑卒中发病具有季节性,在脑卒中预防工作中要充分考虑其发病的季节特点,并采取相应的措施。

Circular distribution analysis of the time of onset for 6186 stroke patients

Objective To analysze the onset time of cerebral hemorrhage(CH),cerebral infarction(CI)and subarachnoid hemorrage(SAH).Method From 1998 to 2002,6186 patients with stroke in Qingdao urban were studied.There were 1179 cases of CH,4821 cases of CI and 186 cases of SAH.Circular distribution analysis was used to study the onset seasonal variation.Results CH onset time had a trend of centralization and the mean angles in January(P<0.05),male in January(P<0.05)and female in February(P<0.05).CI onset time had a trend of centralization and the mean angles in October(P<0.05) and no difference between male and female.SAH onset time had a trend of centralization and the mean angles in October(P<0.05),male in September(P<0.05) and female in October(P<0.05).Conclusion Stroke has a seasonal rhythm in Qingdao urban.It should be considered enough when the preventive works for stroke are made.
