摘要
目的探讨高温对武汉市心脑血管疾病死亡的影响。方法收集2003年武汉市死亡资料及气象资料描述武汉市2003年夏季日最高气温与心脑血管疾病日死亡数的时间序列,对高温期和非高温期的心脑血管疾病平均日死亡数进行了比较,分析了夏季日最高气温与心脑血管疾病逐日死亡率的关系。结果在2003年夏季高温期有明显的死亡高峰,高温期的心脑血管疾病平均日死亡数、男性和女性平均日死亡数分别是非高温期的1.92、1.56和2.34倍,高温期的死亡总数占该年夏季心脑血管疾病死亡总数的31.8%。心脑血管疾病死亡率明显增加的日最高气温临界值是36℃,单位温度死亡危险度为2.8/100万。结论武汉市高温天气对心脑血管疾病死亡有显著影响。
Objective To explore the impacts of high temperature on death caused by cerebro-cardiovascular diseases in Wuhan. Methods The time series of maximum daily temperature and daily death number of cerebro-cardiovascular diseases were described, the average daily death in continuous high temperature periods was compared with that in non-continuous high temperature periods, and the relationship between daily maximum temperature and daily mortality of cerebro-cardiovascular diseases in summer was analyzed in 2003. Results There was a death peak during the continuous high temperature periods in summer, 2003. The average cerebro-cardiovascular death number of male, female and both in continuous high temperature periods was as high as 1.56, 2.34 and 1.92 times of that in non-continuous high temperature periods respectively, and the deaths in continuous high temperature periods accounted for 31.8% of the total cerebro-cardiovascular deaths in the whole summer. The temperature above which the daily cerebro-cardiovascular mortality obviously increased with the temperature increasing was 36 ℃ in Wuhan, and the unit temperature risk of mortality was 2.8 per million. Conclusion The extreme high temperature may obviously increase the cerebro-cardiovascular death in Wuhan.
