| Abstract: | The principal causes of death for persons aged between 55 and 64 years are identified from Australian mortality data for 1966 and 1977. Four conditions--ischaemic heart disease, cerebrovascular disease, bronchial carcinoma, and chronic airways disease--account for 62% of deaths in this age group, with 36% of deaths being attributed to ischaemic heart disease. Changes in age-specific mortality rates during the period from 1966 to 1977 are described for each of these four conditions. There have been substantial reductions in mortality from vascular disease in both sexes, and this trend has accelerated since 1974. A recent fall in mortality from bronchial carcinoma and chronic airways disease is indicated for males, while death rates from these disorders continue to increase rapidly for females. The introduction of beta-blockade in the treatment of vascular disease, and changes in the pattern of cigarette smoking are discussed in relation to these mortality trends. |
