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 the occurrence of heat stroke and meteorological factors. Methods The daily meteorological factors from June to August in Wuhan from June to August in 1994 and daily sunstroke cases were selected as research objects. Meteorological parameters were screened by single factor correlation analysis and multiple regression analysis was used to establish the regression equation. Results The results of single factor correlation analysis showed that sunstroke was correlated with daily average temperature, daily maximum temperature, daily minimum temperature and daily average humidity. Multiple regression analysis showed that sunstroke was mainly associated with daily average temperature Related; at T day average temperature> 30 ℃ sunstroke and daily average temperature, daily wet related. Conclusions The incidence of heat stroke is related to the average daily temperature and average daily wetness. As the daily average temperature increases, the synergistic effect of daily average wetness becomes more and more obvious.
