Abstract:
Objective To research the relationship between high temperature and population death in a district in Nanjing. Methods Using Microsoft Excel 2000 and SAS 8.0 software, firstly, respectively analyzed the impact of daily highest and lowest temperature from 1994 to 2002 on daily death in summer and winter, then studied the relationship between daily highest temperature and total death, age-specific and sex-specific death in summer of 1998 based on the study of the climate characteristic of Nanjing. Results In summer, the highest temperature which could reach to 40.7℃ emerged mostly in July and August, and when the highest temperature was higher than 35℃, mortality increased obviously as the temperature increasing. The relative humidity was more than 70% in most time of the year round. In summer of 1998, the excessive death on hot days accounted for 11.3% in which the old people occupied the majority, and two death peak appeared in July and August, the former higher than the latter. Conclusion The high temperature and high humidity may obviously increase mortality, especially in the old people, in Nanjing.
