| 研究実績の概要 |
The aim of this research is to assess seasonality of mortality systematically and to explore how it may be impacted by ambient temperature under a changing climate, by using sophisticated statistical models to analyse time series daily data from multiple countries.
In 2020, I finished data analysis for multiple cities from multiple countries and summarised the results in three research papers. The first paper examined seasonality of mortality in Japan and the impact of climate change on its temporal changes, and this paper has been submitted to Environmental Health and Preventive Medicine. The second paper investigated the role of influenza and temperature in the seasonal variation of mortality in Japan, which has been submitted to BMJ Open. The third paper included 138 868 448 deaths from all or non-external causes in 719 locations in 34 countries, 39 777 149 deaths from cardiovascular diseases, and 12 805 050 deaths from respiratory mortality in 519 locations in 22 countries; the seasonal variation in mortality and the contribution of temperature was investigated in these locations. To our knowledge, this is by far the largest study on seasonality of mortality. The third paper has been submitted to International Journal of Epidemiology. Currently, these papers are under review. Furthermore, I have presented the results to colleagues at local and international online seminars.

| 次年度使用額が生じた理由 |
Due to the COVID19 pandemic, several business trips in FY2020 were canceled. Therefore, I was not able to travel overseas to attend conferences.
For FY2021, (1) I have submitted several papers to academic journals, and the article processing charges will be paid to journals after acceptance; (2) I am preparing another manuscript on the methodology. Therefore, I plan to buy a few books on bio-statistics, edit the language before submission, and pay for the article processing charges.
