Diabetes
Diabetes is a chronic condition characterised by high levels of glucose (sugar) in the blood. It is caused either by the body’s inability to produce insulin (a hormone produced by the pancreas to control blood glucose levels) or by the body not being able to use insulin effectively. These estimates include people with the following types of diabetes:
- type 1 (non-preventable autoimmune disease mainly developing in childhood)
- type 2 (largely associated with modifiable risk factors but also genetic and family related risk factors)
- type unknown (AIHW 2020h).
The prevalence of diabetes (based on self-reporting) among older people (aged 65 and over) has doubled over the last 2 decades – from 8.5% in 1995 to 16.8% in 2017–18. This increase is likely due to several factors, including an increased prevalence of risk factors, improved public awareness, better detection techniques and improved survival through management strategies.
In 2017–18, 607,700 Australians aged 65 and over self-reported diabetes as a long-term health condition (ABS 2018a). The prevalence of diabetes for those aged 65–74 was more than 3 times as high as for those aged 45–54. Older men aged 65–74 were more likely than women of the same age to report having diabetes (19% compared with 12%, respectively) (AIHW 2020h).
While the self-reported rate of diabetes for Australians aged up to 64 has remained relatively stable since 2001, it has increased for older Australians. In 2017–18, 15% of Australians aged 65–74 self-reported having diabetes, an increase from 13% in 2001. Similarly, in 2017–18, 19% of Australians aged 75 and over self-reported diabetes, an increase from 11% in 2001 (ABS 2018a).
More information about diabetes is available in Health—service use (see ‘Pharmaceutical use’ and ‘Hospitals’), and Health—status and functioning (see ‘Burden of disease’).
Mental health
Mental health is influenced by a combination of psychological, biological and socioeconomic or cultural factors (such as income levels and living conditions) (Slade et al. 2009). Good mental health can support healthy behaviours in old age. In turn, poor mental health can be associated with poor physical health.
Poor mental health can be defined in different ways but commonly it includes mental illnesses such as anxiety disorders, affective disorders (such as depression), psychotic disorders and substance use disorders (AIHW 2020a). People may have experienced poor mental health over their lifetime, or they may have experienced a recent onset; for example, due to stressors such as loss, bereavement or health issues (AIHW 2015).
Mental illness may be more common among particular groups of older Australians, such as older carers, people in hospital and people with dementia (RANZCP 2016; Rickwood 2005). People living in residential aged care are another subgroup at higher risk of poor mental health. At 30 June 2019, of those people living in permanent residential aged care, the majority (87%) were diagnosed with at least one mental health or behavioural condition and 49% had a diagnosis of depression (AIHW 2020l).

The prevalence of mental illness decreases with age. Using the Kessler Psychological Distress Scale (K10)—which includes questions about people’s level of nervousness, agitation, psychological fatigue and depression—the 2017–18 ABS NHS showed that:
- almost 7 in 10 (68%) people aged 65 and over reported low levels of psychological distress in the past 4 weeks
- 1 in 5 (19%) reported moderate distress levels
- 10% reported high or very high levels (ABS 2019).
COVID-19 and mental health
Older Australians have been shown to have generally lower levels of anxiety and worry over the course of 2020 than younger Australians. Australian National University research found this in May, August and October 2020. However, between May and August 2020, older people aged 65–74 years had the largest increase in anxiety and worry, up to 57% from 47%. Similarly, older people aged 75 and over were the only age group that saw a significant worsening in psychological distress between May and August 2020 (Biddle et al. 2020).
The ABS Household Impacts of COVID-19 Survey showed that, in June 2021, around 1 in 10 (10%) older people (aged 65 and over) reported high or very high distress. However, the majority of older people reported low distress levels (66%). Around 1 in 6 (16%) older people reported feeling nervous at least some of the time in the last 4 weeks (ABS 2021).

Oral health and disease
Oral health relates to the ability to eat, speak and socialise without discomfort or active disease in the teeth, mouth or gums. Oral health generally deteriorates over a person’s lifetime: it can be affected by biomedical risks, as well as clinical conditions and age-related functional impairments, such as increased difficulty with personal care.
Oral disease can in turn have an impact on people’s health and wellbeing more broadly. The 2 main forms of oral disease affect the teeth (dental caries or decay) and gums (periodontal disease). Oral disease also includes conditions such as mouth ulcers, oral cancers, tooth impactions and misaligned teeth, and traumatic injuries to the teeth and mouth (AIHW 2020j).
The proportions of older people with at least one natural tooth who report fair or poor oral health have increased over time (capturing different cohorts of older people):
- For those aged 65–74, the proportion with fair or poor oral health increased from 18% in 2004–06 to 26% in 2017–18.
- For those aged 75 and over, it increased from 18% to 23% (AIHW 2020j).
Among older Australians, the proportion with at least one tooth with untreated decay increased from 22% in 2004–06 to 27% in 2017–18.
Between 2013 and 2017–18, the proportion of older people who had experienced toothache in the past 12 months also increased, from 8.9% to 13%. The proportion of older people who reported feeling uncomfortable with the appearance of their teeth, mouth or dentures in the past 12 months increased from 21.7% in 2013 to 29.1% in 2017–18. Compared with other age groups at both of these time points, older people were the least likely to report feeling uncomfortable with the appearance of their teeth, mouth or dentures (AIHW 2020i).
In 2017–18, the average number of missing teeth for older Australians (aged 65 and over) was 13.7, higher than the 2.5 for young people aged 15–24 (the full adult set is 32). Other selected aspects of oral health and disease were also high for older people (Table 3B.2).

Many of these oral health issues and disease have also increased over time. For more information about progress against key performance indicators used to monitor performance of the strategies in Australia’s National Oral Health Plan 2015–2024, see AIHW (2020i).
Ear health and hearing
Poor ear health and poor hearing can have implications for communication, social participation, independent living and employment (AIHW 2016). Middle-age hearing loss can also be linked to an increased risk of later developing dementia (Livingston et al. 2017). Ear disease and the associated hearing loss can develop over time for many reasons (such as injury, infection or genetic causes) but, for the most part, these are preventable (AIHW 2018).
In 2017–18, an estimated 1 in 3 (34%) people aged 65 and over reported complete or partial deafness as a long-term health condition (ABS 2018b). The 2018 ABS Survey of Disability Ageing and Carers also estimated that among older people, 7.7% (300,000 people) had a main long-term health condition of the ear (diseases of the ear and mastoid process), with a higher proportion of older men affected (11%) than older women (4.7%) (ABS 2019).
Eye health and sight
Chronic eye conditions vary in their presentation, treatment and consequences, but many are commonly experienced by older people. In 2017–18, the majority of people aged 65 and over reported a chronic eye condition (93%, 3.4 million people). The most common chronic eye condition was long-sightedness (62%), followed by short-sightedness (41%), presbyopia (9.6%) – a type of long-sightedness – and cataracts (9.1%) (ABS 2018b).
The prevalence of long-term eye conditions was broadly similar for both older men and women (AIHW 2021b). Looking at selected eye conditions among older Australians between 2007–08 and 2017–18, the prevalence by sex remained relatively stable (Table 3B.3).

Chronic pain
Chronic pain is pain that lasts beyond normal healing time after injury or illness. It is a common and complex condition, and the pain experienced may be anything from a mild niggle to debilitating. Older people with chronic pain can be at an increased risk of falling, reduced mobility and disability. In turn, people who experience falls, reduced mobility or disability may be at an increased risk of pain. Pain can also affect people’s ability to look after themselves and remain independent in older age (AIHW 2020e; Eggermont et al. 2014; Stubbs et al. 2014).
Chronic pain is more likely to affect women and older people. In 2016:
- 1 in 5 (20%) people aged 65–74 reported having chronic pain, increasing to 22% of those aged 75–84 and 24% of those 85 and over.
- Among women, chronic pain was 1.8 times as high in those aged 85 and over (28%) as in those aged 45–54 (16%).
- Among men, chronic pain was 1.3 times as high in those aged 85 and over (18%) as in those aged 45–54 (13%) (AIHW 2020e).
