目的　探讨人群脑卒中发病的时间模式 ,以提供病人进入脑卒中发作的触发时间。方法　根据WHO MONICA方案脑卒中诊断标准 ;时间模式定为天 周、季节、月份。计算人群脑卒中不同时间发生的百分比 ,用 χ2 进行率的显著性检验。用多元逐步回归进行多因素分析。结果　冬季是脑卒中发生和复发的高峰 (男性χ2 =7.0 2 ,P =0 .0 0 8;女性χ2 =12 .32 ,P =0 .0 0 0 4 ) ;城乡人群脑卒中天 周发病频度截然不同 (城市星期一高发 ,农村星期六高发 ) ;单因素首、复发与季节发病呈正相关(r =0 .0 32 ,P =0 .0 1) ,多因素分析脑卒中存亡与季节呈显著正相关 (^β =0 .0 36 ,P =0 .0 0 5 )。结论　认识生理节奏的变化规律 ,了解和适应外部环境触发因素的变化 ,改变不良生活行为是预防、减轻和减少脑卒中发生、发展和复发的重要环节 Objective To explore the time pattern of stroke in the population to provide the triggering time for the patient to enter the stroke. Methods According to WHO MONICA program criteria for stroke; time pattern as the days of the week, the month of the month. Calculate the percentage of people with stroke at different times, using the χ2 rate of significance test. Multivariate analysis was performed using multiple stepwise regression. Results The peak of stroke and recurrence was found in winter (male χ2 = 7.02, P = 0.080; female χ2 = 12.32, P = 0.00004); incidence of stroke in urban and rural areas was higher (Mon-city high incidence in rural areas on Saturday high incidence); single factor, relapse and seasonal incidence was positively correlated (r = 0.322, P = 0.01), multivariate analysis of stroke survival and the season was significant Positive correlation (^ β = 0. 36, P = 0. 0 0 5). Conclusions It is an important link to prevent, reduce and reduce the occurrence, development and recurrence of stroke by understanding the changing rules of circadian rhythms, understanding and adapting the changes of triggers of external environment and changing the bad living behaviors
