Cervical cancer mortality in Australia: contrasting risk by Aboriginality, age and rurality

Background The poor health status of Australia's indigenous population is reflected in relatively high mortality rates from almost all causes, including preventable causes such as cervical cancer, where the rate is six to eight times that of non-Aboriginal women. However, there is little information on the geographical distribution of risk, an important issue for service deployment. This study examined the risk of death from cervical cancer in relation to Indigenous status, age and rurality. Methods Data from death registers from Australian states and territories who have identified Aboriginal people were examined for 1986-1997 to obtain a list of all deaths where the primary cause was cancer of the cervix. The data categorized females by 5-year age group, by metropolitan, rural or remote category and by Indigenous status. Mean age at death and standardized mortality ratios for deaths from cervical cancer were calculated for Aboriginal compared with non-Aboriginal women in metropolitan, rural and remote areas. Results The risk of death from cervical cancer for Aboriginal women compared with non-Aboriginal women increased by 4.3-fold for metropolitan areas, 9.7-fold for rural areas and 18.3-fold for remote areas. Conclusions Aboriginal women in rural and remote areas of Australia are at significantly higher risk of death from cancer of the cervix than either Aboriginal women in metropolitan areas or non-Aboriginal women in any area. This result raises questions about access to services for prevention and early diagnosis and other factors that might impact on the incidence and natural history of the disease.
