摘要
目的了解上海市奉贤区居民、脑卒中的发病季节和时间规律,为制定有效的干预措施提供科学依据。方法收集奉贤区2011—2013年脑卒中患者发病病例5 401名,了解脑卒中发病的时间规律,用圆分布法分析其发病集中趋势。结果①脑出血发病呈现冬季多发,占全年的28.9%;夏季发病最低,占20.6%(P<0.05);而脑梗死发病则提示春夏季多发(P<0.05)。②脑出血的的发病有明显集中趋势,平均角为358.580 5°,相当于12月29日(P<0.05);而脑梗死平均角为142.379 6°,相当于5月24日,且有统计学意义(P<0.05)。结论奉贤区居民脑卒中发病有时间差异,脑出血发病集中在冬季(12月至次年2月),而脑梗死发病集中在春夏季(3—8月),医疗卫生机构在日常防治工作中要充分考虑其发病的季节性特点,在高发季节来临之前,加强宣传教育和社区干预,降低脑卒中发病率。
[Objective] To understand the seasonal and temporal regularity of stroke among residents in Fengxian District of Shanghai, provide scientific evidence for developing effective intervention measures. [Methods] 5 401 stroke patients were collected in Fengxian District during 2011-2013, to investigate the temporal regularity of stroke, and the central tendency of stroke was analyzed by the circular distribution method.[ Results ] ①The cases of cerebral hemorrhage mainly occurred in winter, which accounted for 28.9%, and cases in summer accounted for only 20.6% （P〈0.05）. The cases of cerebral infarction mainly occurred in spring and summer （P〈0.05）. ②The incidence of cerebral hemorrhage had obvious central tendency, the average angle was 358.580 5°, equivalent to 29th December （P〈0.05）. The average angle of cerebral infarction was 142.379 6°, equivalent to 24th May, and there was statistical significant difference （P〈0.05）.[ Conclusion ] There is a temporal difference in the stroke onset, the cases of cerebral hemorrhage concentrate in winter （December to February of next year）, while the cases of cerebral infarction concentrate between spring and summer （March to August）. In the daily work of control and treatment, the medical and health institutions should consider the seasonal characteristics of the stroke, and strengthen publicity and community intervention to reduce the incidence of stroke before the high-risk seasons.
