| Outline of Annual Research Achievements |
The trends of the burden of ischemic heart disease, stroke,and cancer, comparing with diabetes, unintentional accidents and all-cause mortality, were conducted for Japanese population. Age-standardized Years of Life Lost per 1000 population (YLL) were estimated by using vital statistical data and life-tables in each year. Trends of segments and average annual percent change (AAPC) were identified and analyzed by Joinpoint regression models.
Between 1950 and 2014, YLLs due to cancer were increased from 29.1 in 1950 to 49.6 in 1996 (AAPC = 1.2%), then declined to 42.3 in 2014 (AAPC=-0.9%). YLLs of stroke increased from 43.0 in 1950 to 59.7 in 1967 (AAPC=2.0%), then declined to 9.8 in 2014 (AAPC=-3.8%). For ischemic heart disease, YLLs was 23.2 in 1950 and 30.0 in 1984 (AAPC=0.8%), then 16.0 in 2014 (AAPC=-1.9%). YLLs of diabetes increased from 0.8 in 1950 to 2.6 in 1974 (AAPC=4.7%), then declined to 1.5 (AAPC=-1.4%).
The decline of YLLs due to cancer mortality was started late and slowly comparing with declines of other causes. Currently, YLLs of death of cancer and ischemic heart disease were higher than those of stroke and diabetes.
An oral presentation about gastric cancer research was done at an international conference, which was related to the risk of burden of cancer study.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Due to the unavailability of data from Taiwan on mortality in two planned cities, the comparison between Tokyo/Osaka and Taipei/Kaohsiung was pending. However, we have conducted the trends analysis for Japanese data about burden of cardiovascular diseases for the past 50 years.
In addition, as a coauthor, the Chinese investigators have submitted an article on the trend of mortality from ischemic heart disease in Chinese population.
|
| Strategy for Future Research Activity |
The analysis of trends of years of life lost from all-cause and main chronic diseases in Japan will be completed and submitted to a scientific journal for publication. Meanwhile, the study on comparison of mortality from stroke in Japan and China will be considered for publishing in a journal.
|
| Causes of Carryover |
Since data from Taiwan were not available for analysis, the plan of attending a scientific conference for the section study was postponed.Therefore, the incurring amount (about 170k) will be used in 2017 fiscal year.
|
| Expenditure Plan for Carryover Budget |
The incurring amount will be used to attend another similar international conference.
