Abstract

A medico-geographical study was made on the vital statistical data concerning three causes of death, viral hepatitis, cirrhosis of the liver and cancer of the liver from 1953 to 1972. This twenty year period was divided into four sections, 1953-1957, 1958--1962, 1963--1967 and 1968?`1972, and total deaths were obtained for each section. Standardized death rates from the three diseases were computed for all the forty-six prefectures by the indirect method using the 1960 census as their standard population, and the values were compared for geographical distribution. Coefficients of correlation between the three causes of death were also computed from the same standardized values. The results are as follows: (1) The standardized death rate from cirrhosis of the liver is higher in south-western Japan(i.e., Kyushu, Shikoku, a part of the Chugoku district and a part of the Kinki district) than in north-eastern Japan except Yamanashi Prefecture. (2) The standardized death rate from viral hepatitis, though on the decrease recently, is higher in south-western Japan than in north-eastern Japan except Fukui and Yamanashi Prefectures. (3) The standardized death rate from cancer of the liver, which shows a gradual increase in incidence, presents almost the same pattern as that of cirrhosis of the liver, being higher in south-western Japan than in north-eastern Japan except Yamanashi Prefecture. (4) The coefficients of correlation indicate that the three causes of death are closely associated with one another in terms of geographical distribution.
