摘要
目的：探讨日平均气温及其它气象因素与中暑发病的关系。方法：以南京市区２６０万自然人群中１９８８、１９９４及１９９５年３个高温气候年份发生的５６３例重症中暑病例，与逐日的３６项气象因素，即Ｘ１～Ｘ６、Ｍ１１～Ｍ１５……Ｍ６１～Ｍ６５，选用多元回归方程，用逐步回归筛选变量建立优化方程。结果：３年各中暑期的日平均气温及日平均最高气温呈逐年下降趋势，但中暑期逐年明显延长。连续３ｄ的平均日气温Ｍ１２及平均相对湿度Ｍ３２较Ｘ１、Ｘ３对日重症中暑人数影响要大，当连续３ｄ平均气温超过３０℃且相对湿度超过７３％时最易出现中暑。结论：日平均气温的变化对机体生理功能的影响较日最高气温更加持久、明显。
Objective:Studing relationship between heat stroke and average air temperature and other meteorological factors in a day.Method:Statistical analysis with multifactorial regression was used to determine relationship of 563 cases of severe heat stroke during 1988,1994,and 1995 and 36 meteorological factors of X 1～X 6 and M 11 ～M 15 ……M 61 ～M 65 in a day.Results:The average air temperature and highest air temperature fell down every year,the period of severe heat stroke was obviously extending year by year.When average air temperature over 30℃ and relative humidity over 73% continued during three days,there had an attack of severe heat stroke(73%).Conclusion:Influence of average air temperature on physiological functions is more lasting and notable than the highest air temperature,so when average air temperature continued three days,incidence of heat stroke may be determined.
