The number of Australians with stages 3 to 5 CKD nearly doubled between 1999–2000 (322,000) and 2011–12 (604,000) (AIHW 2018). This increase was mostly driven by an increase in CKD stage 3, due to growth in the size of the population aged 65 and over.
Variation between population groups
Aboriginal and Torres Strait Islander people
An estimated 18% of Indigenous Australian adults (59,600 people) had biomedical signs of CKD, according to the ABS 2012–13 National Aboriginal and Torres Strait Islander Health Measures Survey (ABS 2014).
Indigenous adults were twice as likely as non-Indigenous adults to have biomedical signs of CKD, after accounting for differences in the age structure of the populations.
Remoteness and socioeconomic area
In 2011–12, the prevalence of biomedical signs of CKD among adults was similar across remoteness areas but increased with socioeconomic disadvantage (Figure 6).
CKD prevalence rates in 2011–12 were:
- similar in Major cities (10.9%), Inner regional areas (11.0%) and Outer regional and remote areas (8.6%).
- highest among those in the lowest socioeconomic area (13.4%) compared with those in the highest socioeconomic area (9.0%).
After adjusting for differences in the age structures of the population, CKD prevalence:
- was 1.3 times as high in Outer regional and remote areas as in Major cities
- was 1.5 times as high in the lowest socioeconomic areas as in the highest socioeconomic areas.
