项目摘要

(1) Correspondence between the meteorological data and city (The word city referred here represents village or town as well as city) : We decided to take the points of Automated Meteorological Data Acquisition System (AMeDAS) within 15km of the barycenter of the city, and to set the calculated average of daily maximum temperature measurements of these points as the city measurement. We used 15km because 10km or 5km left some cities without AMeDAS points.(2) Preparation of data for the analysis : Prime Minister's Office provided the computerized population data by age and sex for each city, Ministry of Health and Welfare provided the computerized death certificate file, and Meteorological Agency provided AMeDAS data. We used city number assigned by Japanese government to combine the above three types of data, and calculated number of deaths, number of person-days by daily maximum temperature category for each city.(3) Comparison between city-based analysis and prefecture-based analysis : In the city-based analysis, we construct prefectural number of deaths and person-days by combining all the cities in the prefecture. On the other hand, in the prefecture-based analysis, we used only one measurement point for each prefecture, which is located in the capital cities. Thus, if there is a difference between the temperature in the capital city and that in other cities, misclassification of deaths and person-days would occur. In this analysis, we used the data in 1995 and restricted the subjects to 65+years old.(4) Result : The misclassification pattern of deaths was so similar to that of person-days that the mortality rates were not biased. This suggests that the prefecture-based analyses studied previously were valid. However, we need to use city-based data in projecting the number of deaths by multiplying mortality rate with corresponding person-days, because the temperature-specific number of person-days is biased.
(1)气象数据与城市的对应关系(这里的城市既表示城市,也表示村庄或城镇):我们决定将自动气象数据采集系统(AMeDAS)中距城市重心15km以内的点作为城市测量点,并将这些点的每日最高气温测量值的计算平均值作为城市测量点。我们使用了15公里,因为距离一些城市10公里或5公里没有AMeDAS点。(2)为分析准备数据:总理室提供了各城市按年龄和性别分列的计算机化人口数据,厚生劳动省提供了计算机化的死亡证明文件,气象厅提供了AMeDAS数据。我们使用日本政府分配的城市编号,将上述三类数据结合起来,按日最高气温类别计算每个城市的死亡人数、人数。(3)基于城市的分析与基于州的分析的比较:在基于城市的分析中,我们将全州的所有城市结合起来,构建了全州的死亡人数和人日数。另一方面,在基于县的分析中,我们只对每个县使用了一个测量点,这些测量点位于首府城市。因此,如果首都城市的温度与其他城市的温度存在差异,就会出现死亡人数和人日的错误分类。在本分析中,我们使用1995年的数据,并将受试者限制在65岁以上。(4)结果:死亡错误分类模式与人日错误分类模式相似,死亡率无偏倚。这表明先前研究的基于县的分析是有效的。然而,我们需要使用基于城市的数据,通过将死亡率乘以相应的人日来预测死亡人数,因为特定温度的人日数是有偏差的。
