目的探讨气象因素与脑卒中发病的关系,为脑卒中的预防提供理论依据和措施。方法对6663例脑卒中患者发病时间与同期巢湖市气象因素的关系进行调查分析研究。结果在全年气温低、气压高的1、2、12月份出血性脑卒中发病率最高,在气温高、气压低的6、7、8月份发病率最低,差异有显著统计学意义(P<0.01),而缺血性脑卒中在1、2、12月份发病率最低,在6、7、8月份发病率最高,两者比较差异有显著统计学意义(P<0.01);缺血性脑卒中与相对湿度密切相关(P<0.05),出血性脑卒中与相对湿度无关(P>0.05)。结论气象因素与脑卒中的发病密切相关,是脑卒中的一个危险因素。
Objective To explore the relationship between meteorological factors and the incidence of stroke so as to provide theoretical basis and measures for the prevention of stroke. Methods The incidence of 6663 cases of stroke patients with the same period of Chaohu meteorological factors were investigated and analyzed. Results The incidence of hemorrhagic stroke was highest in January, December and December with low temperature and high air pressure, and lowest in June, July and August with high temperature and low air pressure, with significant difference (P < 0.01). However, the incidence of ischemic stroke was the lowest in January, December and December, and the incidence was the highest in June, July and August. There was significant difference between the two groups (P <0.01) Stroke was closely related to relative humidity (P <0.05), and hemorrhagic stroke was not related to relative humidity (P> 0.05). Conclusions Meteorological factors are closely related to the incidence of stroke and are a risk factor for stroke.
