老年人群耐受温度的初步探索

GROPE FOR THE CRITICAL TEMPERATURE IN THE OLDER

[目的]比较室外温度(T_a)与个体暴露温度(T_p)之间的关系,探索正常老年人群耐受温度的临界值(T_c)。[方法]在南京玄武区和鼓楼区选择有责任心的40户老年家庭进行HOBO(自动便携式温湿度监测仪)跟踪监测。[结果]夏天T_a均高于室内温度(T_r)和T_p(P﹤0.05),冬天T_a均低于T_r和T_p(P﹤0.05),二维散点图阵显示夏、冬天的T_a、T_r和T_p3者间均有线性相关,老年人群夏天热耐受的温度为31℃～32℃,冬天冷耐受的温度为3℃～4℃。[结论]T_a与T_p之间差异有统计学意义,当外界温度超过了老年人的耐受能力,人们开始采取相应的措施。

[Objective] To research the relationship between ambient temperature （T,） and personally exposed temperature （Tp）, and grope for the critical temperature （Tc） to personally tolerance. [Methods] Ta. in-room temperature （Tr） and Tp were measured for one year with portable monitors （HOBO H8 Loggers, Onset Computer Corporation） for 40 houses. [Results] Ta was higher than T, and Tp （P〈 0.05） in summer. Ta was lower than Tr and Tp （P〈 0.05） in winter. Two-way seatterplot matrix suggested that among Ta . Tr and Tp , it had linear correlation. The critical temperature in summer was 31 ℃ - 32℃. The critical temperature in winter is 3℃ -4℃. [Conclusion] There is obvious difference between Ta and Tp. When Ta exceeds the elder＇s ability of temperature stress tolerance, people begin to take some measures to control temperature.
