[[Cohort analysis of mortality from three major adult diseases]].

The authors present cohort mortality rates for Japan by five-year age interval for all causes of death and for malignant neoplasms, cerebrovascular disease, and heart disease. The calculations are based on vital statistics data for 1947-1982 and period and cohort life tables for 1891-1982 published by Zenjo Nanjo and Kazumasa Kobayashi. "Ratios of individual cause to all causes in each age were calculated and applied to [a] mortality matrix derived from Nanjo-Kobayashi's life tables. Age-specific period and cohort mortality rates for each cause were calculated from [the] cause-specific mortality matrix.... Trends and age patterns of cohort mortalities and ratios of mortalities in successive cohort and age group were investigated." (SUMMARY IN ENG)
