Indicator 3.7 Prevalence of cardiovascular disease among people with diabetes

Consideration

These estimates are based on relatively small numbers and are associated with large sampling error. Due to small numbers, age-standardised proportions were not derived.

Overview

In 2017–18, an estimated 660,000 Australian adults with self-reported diabetes had cardiovascular disease (CVD), corresponding to 57% of adults with diabetes, based on self-reported diabetes and cardiovascular data from the National Health Survey (NHS).

Trends

The unadjusted prevalence of cardiovascular disease among people with diabetes varied across the years:

  • 58% in 2007–08
  • 53% in 2011–12
  • 64% in 2014–15
  • 57% in 2017–18 (Figure 3.7.1)

Age and sex

There was no difference in the prevalence of CVD among men and women with self-reported diabetes, and proportions increased with age (Figure 3.7.1).

Population groups

There was no difference by remoteness or socioeconomic areas (Figure 3.7.2). The proportions for both remoteness and socioeconomic areas have a high margin of error and should be used with caution.

State and territory

The prevalence of CVD among men and women with self-reported diabetes varied across the states and territories (Figure 3.7.2). The proportions for Western Australia, Tasmania and Australian Capital Territory have a high margin of error and should be used with caution.

Aboriginal and Torres Strait Islander people

Based on self-reported data from the National Aboriginal and Torres Strait Islander Health Survey (NATSIHS), an estimated 36,600 (58%) of Indigenous Australians with diabetes had CVD in 2018–19. In 2017–18, 57% of non-Indigenous adults with diabetes had CVD, based on self-reported data from the NHS (Figure 3.7.2).

3.7 Prevalence of cardiovascular disease among adults with diabetes, by age group and sex, 2007–08 to 2017–18 and by selected population groups, 2017–18

Trends figure 3.7.1 shows the prevalence of cardiovascular disease among people with diabetes increased from 58% in 2007-08 to 64% in 2014-15. In the years following, the prevalence decreased to 57% in 2017-18. The prevalence of cardiovascular disease among people with diabetes remained highest among those aged 75+ between 2007-08 and 2017-18.

Population group figure 3.7.2 shows in 2017-18, 57% of persons with diabetes had cardiovascular disease. Prevalence was highest among those aged 75+, with around 80% of males and 68% of females having both diabetes and cardiovascular disease. Around 58% of Indigenous Australians with diabetes also had cardiovascular disease, with prevalence being highest among those aged 65+ (71%). Prevalence was similar by remoteness level yet increased with socioeconomic disadvantage. Among the states and territories, the prevalence of CVD among people diabetes ranged from 46% in Western Australia to 61% in Victoria.
