Aboriginal deaths in Western Australia: 1985-89 and 1990-94.

OBJECTIVE

To examine death data for Aboriginal and non-Aboriginal persons in Western Australia (WA) in 1985-89 and 1990-94.

METHODS

Population estimates were provided by the Health Information Centre of the WA Health Department based on data from the Australian Bureau of Statistics (ABS). Death data came from the WA Registrar-General's Office. Standard methods were used to obtain rates and levels of significance.

RESULTS

Main causes of deaths among Aboriginal males in 1990-94 were circulatory conditions, respiratory, injury and poisoning, neoplasms and endocrine diseases; in Aboriginal females they were circulatory, neoplasms, endocrine diseases, respiratory diseases, and injury and poisoning. From 1985-89 to 1990-94, the Aboriginal male all-cause age-standardised death rates fell 3% (ns) while the non-Aboriginal male rate fell 11% (p < 0.05). The Aboriginal female all-cause death rate rose 11% (ns) while the non-Aboriginal rate fell 5% (p < 0.05). The all-cause death rate ratio (Aboriginal:non-Aboriginal) changed from 2.4 to 2.6 (males) and 2.5 to 2.9 (females). There was a major increase in deaths from endocrine diseases among Aborigines and non-Aborigines. This increase was proportionally much greater among Aborigines. In non-Aborigines there was a significant decrease in deaths from circulatory diseases (mainly ischaemic heart disease); this did not occur among Aborigines.

CONCLUSIONS

Over the study period, Aboriginal health standards, as reflected by death rates, apparently worsened relative to non-Aboriginal standards.

IMPLICATIONS

Better health promotion, disease prevention and disease care are required to help achieve acceptable health standards among Aboriginal peoples.
