An analysis was done on the trend of relationship of deaths from tuberclosis with deaths from cerebrovascular, neoplasm and heart disease separately in the period of 1902-1973 in Japan by using the ecologic model for competition with each other.
The results obtained were as follows:
1) There was a close relationship between the decreasing trend of deaths from tuberclosis and the increasing trend of deaths from neoplasm, cerebrovascular, and heart disease separately.
2) The trend of the relationship between deaths from neoplasm and from cerebrovascular disease is gradually increasing to the equilibrium point and it seems that it will decrease after that point.
3) On cross-sectional observation in the period of 1935-1955, the prefecture that had the higher rate of death from tuberclosis had a tendency to have the lower rate of death from cerebrovascular disease and neoplasm.
4) In 1973, it seemed that the prefecture that had the higher rate of death from cerebrovascular disease was also had the higher rate of death from neoplasm.
