Notes on the data: Aboriginal premature mortality by selected cause

Deaths from respiratory system diseases, Aboriginal people aged 0 to 54, 0 to 64 and 0 to 74 years, 2013 to 2017

 

Policy context:  Respiratory system diseases are those that affect the respiratory tract (upper airway, trachea, bronchus and lung). They include cancers of the respiratory system, chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD), pneumonia, influenza and other respiratory diseases [1].

Respiratory system diseases are associated with a number of contributing factors, including poor environmental conditions, socioeconomic disadvantage, risky behaviour (particularly tobacco smoking, alcohol use, and substance use) and some previous medical conditions [2][3]. Infants and children are particularly susceptible to developing respiratory conditions, due to factors such as exposure to tobacco smoke, poor environmental conditions, and poor nutrition [2][3].

During 2013 to 2017, respiratory diseases caused 8% of all deaths of Aboriginal and Torres Strait Islander people (888 deaths) [4]. Fifty-three percent were attributed to COPD, 4% to asthma and 19% to pneumonia and influenza. Aboriginal and Torres Strait Islander people die from respiratory system diseases at twice the rate of non-Indigenous people.

The data show that for 2013 to 2017 almost three quarters (72.5%) of all deaths of Aboriginal and Torres Strait Islander people from circulatory system diseases occurred before 75 years of age, 44.6% before 65 years and 25.0% before 55 years – details here. This was over three times the proportion for the non-Indigenous population at ages 0 to 74 years (72.5% c.f. 23.7%, a rate ratio of 3.06).

Deaths data

For deaths data released since 2007, the ABS has applied a staged approach to the coding of cause of death which affects the number of records available for release at any date. In each release, the latest year’s data is preliminary, the second latest is revised and the data for the remaining years is final. For further information about the ABS revisions process see the following and related sites: http://www.abs.gov.au/ausstats/abs@.nsf/Lookup/3303.0Explanatory+Notes12012.

Data quality

Almost all deaths in Australia are registered. However, Indigenous status is not always recorded, or recorded correctly. The incompleteness of Indigenous identification (referred to as completeness of coverage) means that the number of deaths registered as Indigenous is an underestimate of the actual number of deaths which occur in the Indigenous population. It should also be noted that completeness of coverage is likely to vary between geographical areas.

While there is incomplete coverage of Indigenous deaths in all state and territory registration systems, some jurisdictions have been assessed by the Australian Bureau of Statistics (ABS) as having a sufficient level of coverage to enable statistics on Aboriginal and Torres Strait Islander mortality to be produced. Those jurisdictions are New South Wales, Queensland, South Australia, Western Australia and the Northern Territory.
