高温对河北省石家庄地区心脑血管疾病死亡的影响

Impacts of high temperature on death caused by cardio-cerebrovascular diseases in Shijiazhuang

目的 探讨高温对石家庄地区心脑血管疾病死亡的影响。方法将监测日按最高气温分为“热日”（I〉34℃）和“非热日”（〈34℃），每个热日的死亡数与该年平均每个非热日的死亡数的差值称为“热日多出死亡数”或“热有关死亡数”。分析2009-2011年夏季（6～8月）日最高气温对该地区人口死亡的影响。结果石家庄地区夏季最高气温多出现在7、8月份，可达41．7℃。该地区夏季最高气温在34℃以上时，随温度的升高死亡数显著增加；“热日”与“非热日”死亡数之比为1.17，60岁以上老年人以及男、女死亡数均在7月15日至8月15日出现高峰。结论石家庄地区的高温天气对心脑血管疾病死亡有显著影响。

Objective To research the relationship between high temperature and population death in cardio-cerebrovascular diseases in Shijiazhuang.Methods The time series of maximum daily temperature and daily death number of cardio-cerebrovascular diseases were described,and the relationship between daily maximum temperature and daily mortality of cardio-cerebrovascular diseases in summer was analyzed.The impact of daily highest temperature in summer from 2009 to 2011 on daily death of cardio-cerebrovascular diseases was analyzed.Results In summer,the highest temperature which could reach to 41.7℃ emerged mostly in July and August,and when the highest temperature was higher than 34℃,cardio-cerebrovascular diseases death increased obviously as the temperature increasing.The relative humidity was more than 70% in most time of the year round.The excessive death in hot days accounted for 10.9% in which the old people occupied the majority.Conclusion The extreme high temperature may obviously increase the cardio-cerebrovascular death in Shijiazhuang.
