| Outline of Final Research Achievements |
In the association between changes in environmental temperature and COVID-19, the increase in the number of out-of-hospital natural deaths coincided with the timing of temperature rises and falls due to seasonal variations, and the increase was rapid in the high temperature environments. The trend of increase in the high-temperature was more pronounced during the pandemic, however, declined to the same level as before the pandemic after the transition to Category V Infectious Diseases. In the high-temperature environment during the pandemic, not only the elderly and those living alone but also those living with housemates were risk groups for out-of-hospital natural deaths.
Analysis of vulnerability factors in deaths in high-temperature environments suggested that undernutrition and dehydration were mortality risks.

| Academic Significance and Societal Importance of the Research Achievements |
今回得られた研究成果は、いずれも国内の夏期およびCOVID-19 パンデミック期間における死亡リスクに関する知見を与えている。
世界的な温暖化が進行している今、これらの知見は、夏期の死亡リスクを低減させようとする試みにおいて有意義な情報を与えるものと考えられる。
