Population Survey on Cerebrovascular and Cardiovascular Diseases: The Ten Years Experience in the Farming Village of Tanushimaru and the Fishing Village of Ushibuka

From the findings at entry examination and the data obtained in the 10 years of follow-up experience, the following conclusion is reached. (1) The mortality from cerebral thrombosis and myocardial infarction has been significantly higher in Ushibuka men than in Tanushimaru men. The increase of sum of skinfold thickness due to a remarkable reduction of physical activity and prevalence of high blood pressure seemed to influence the high mortality from cerebral thrombosis and myocardial infarction. (2) The higher trend of cerebral hemorrhage in the men with hypertension at Tanushimaru appeared to be influenced by the low serum protein concentration with A.G ratio abnormalities due to low dietary protein and by the higher elevation of blood pressure after exercise.
