摘要
目的探讨高温中暑的发生与气象因素的关系。方法以武汉市1994—2010年每年6—8月的逐日气象因素与逐日的高温中暑病例为研究对象,并通过单因素相关分析筛选气象参数,多元回归分析建立回归方程。结果单因素相关分析结果表明,高温中暑与日均温、日最高温、日最低温、日均湿度相关;多元回归分析结果表明,在T日均温≤30℃情况下中暑主要与日均温有关;在T日均温>30℃情况下中暑与日均温、日均湿都相关。结论高温中暑的发病与日均温、日均湿有关,并随着日均温的升高,日均湿的协同作用越来越明显。
[ Objective] To explore the relationship between heat stroke and meteorological factors. [ Methods] By using the detailed data of the daily heat stroke cases and weather conditions of June to August from 1994 - 2010 in Wuhan City, meteorological param- eters were selected by univariate analysis, and regression equation was created by multiple regression analysis. [ Results ] The re- suits of univariate analysis showed the morbidity of heat stroke correlated with the daily mean temperature, daily maximum tempera- ture, daily minimum temperature, daily mean relative humidity; the results of multiple regression analysis show the morbidity of heat stroke correlated with the daily mean temperature under the T_mean≤30 ℃ and mainly correlated with the daily mean tempera- ture and daily mean relative humidity under the T_mean= ≤ 30 ℃. [ Conclusion ] The morbidity of heat stroke correlates with the daily mean temperature and daily mean relative humidity, and daily mean relative humidity has a strong synergism with the ascent of daily mean temperature.
