既存資料に基づく徳島県における高糖尿病死亡率の原因についての考察

The purpose of this study is to review the pathogenesis of diabetes mellitus in Tokushima Prefecture from existing data and papers for figuring out the cause. Diabetes mellitus has been recently a main serious one of lifestyle-related diseases. The problem is not only hyperglycemia deprived from diabetes mellitus but also such as diabetic nephropathy, diabetic neuropathy, blindness, stroke and cardiovascular disease accompanied by the progress of diabetes. Thus, those diseases decrease a quality of life of the patients. Diabetes mellitus is thought to be a serious disease in the world and the number of the affected patients has been on the rise. International Diabetes Federation（IDF）estimates the number of diabetic patients and subjects with impaired glucose tolerance will be ３８０million（７．３％）and ４１８ million（８．０％）against the world’s population of ７．９ billion in ２０２５. The sign is not limited in developed country and also severely affected developing country. In Japan also, the number of the patients increases year by year and the Ministry of Health, Labour and Welfare strongly takes a campaign against diabetes. Tokushima Prefecture has the highest diabetic mortality in Japan from １９９３ to ２００６, seventh place in ２００７ but first place again in ２００８. However, we cannot find factors degrading diabetes mellitus or effecting diabetic mortality. It was suggested that unknown factor or a factor beyond our expectation as well as general factors causing diabetes mellitus should be investigated.
