Conditions that affect the bones, muscles and joints are known as musculoskeletal conditions. These conditions include long-term (chronic) conditions such as osteoarthritis, rheumatoid arthritis, juvenile arthritis, back pain and problems, gout, and osteoporosis or osteopenia (low bone density) (see Glossary).
Chronic musculoskeletal conditions affect almost 3 in 10 (29%) Australians. Self-reported data from the Australian Bureau of Statistics 2017–18 National Health Survey (NHS) provide estimates of the number of Australians affected by musculoskeletal conditions. These data indicate that, of the nearly 7.0 million people with chronic musculoskeletal conditions, 4.0 million (16% of all Australians) had back pain and problems (the most common musculoskeletal condition), 3.6 million (15%) had arthritis and 924,000 (3.8%) had osteoporosis (ABS 2018a). These rates have remained relatively consistent since 2007–08 (Figure 1).
This time-series shows that the proportion of persons with arthritis has remained similar between 2007–08 and 2017–18 for both males (around 12%) and females (around 18%).

Females and older people were more likely to have chronic musculoskeletal conditions. The 2017–18 NHS shows that:
This chart shows that 3% of females and 2% of males aged 0–44 had arthritis, while 61% of females and 40% of males aged 75 and over had arthritis. A similar pattern of increasing prevalence in females and older persons was observed in the prevalence of musculoskeletal conditions; 13% of females and 14% of males aged 0–44 had a musculoskeletal condition, while 76% of females and 59% of males aged 75 and over had a musculoskeletal condition.
Figure 2 data table (130KB XLSX)
People with musculoskeletal conditions often have other long-term conditions. This is called ‘comorbidity’, which describes any additional disease that is experienced by a person with a disease of interest (the index disease).
In the 2017–18 NHS, for people aged 15 and over with:
Osteoporosis, 85% had at least one other chronic condition
Arthritis, 74% had at least one other chronic condition
Back pain and problems, 64% had at least one other chronic condition
The number of comorbidities varies by age and sex. For example, the proportion of people with back pain and problems who had at least one other chronic condition increased with age, from 47% (aged 15–44) to 85% (aged 65 and over). Among those with back pain and problems, the proportion of people with comorbidities was higher in females than males across all age groups (Figure 3).
Among persons with arthritis aged 15–44, 76% of females and 63% of males had at least one other chronic condition. For those aged 65 and over, 76% of females and males with arthritis had at least one other chronic condition.

Musculoskeletal conditions often co-occur among people aged 45 and over. Compared with people without these conditions:
Mental and behavioural conditions are a common comorbidity in people aged 45 and over with musculoskeletal conditions. Compared with people without these conditions, mental and behavioural conditions were:
Adjusting for differences in the age structure of the groups did not affect the pattern of these results.
Among persons aged 45 and over with arthritis, 36% had back pain and problems, compared with 20% in persons without arthritis. Additionally, 30% of persons aged 45 and over with arthritis had mental and behavioural conditions, compared with 18% of persons without arthritis.

Chronic musculoskeletal conditions are large contributors to illness, pain and disability in Australia. People with these conditions self-report higher rates of poor health, psychological distress and pain, after adjusting for age (Figure 5). This may affect their ability to participate in social, community and occupational activities (Briggs et al. 2016). The 2018 Survey of Disability, Ageing and Carers found that, of the people with disability in Australia, an estimated 13% had back problems and another 13% had arthritis as the main long-term health condition causing the disability (ABS 2019b).
This graph shows that 11% of persons with arthritis rated their self-assessed health status as ‘poor’, compared with 4% of persons without arthritis. Similarly persons with arthritis were more likely to self-report very high psychological distress (9% compared with 3%) and very severe bodily pain (4% compared with 1%).

Ill health caused by musculoskeletal conditions can have both a human and a financial cost. According to the Australian Burden of Disease Study 2015, musculoskeletal conditions contributed to:
Some of the total burden due to musculoskeletal conditions can be attributed to modifiable risk factors. In 2015:
Overweight and obesity contributed to:
Occupational exposures and hazards contributed to:
See Burden of disease for information on definitions and the burden of disease associated with these conditions.
The Australian Disease Expenditure Study found that Musculoskeletal conditions was the disease group with the highest estimated expenditure in 2015–16, costing the Australian health system $12.5 billion (11% of total disease expenditure) (AIHW 2019c). See Health expenditure.
Musculoskeletal conditions are usually managed by general practitioners and allied health professionals. Treatment can include physical therapy, medicines (for pain and inflammation), self-management (such as diet and exercise), education on self-management and living with the condition, and referral to specialist care where necessary (WHO 2019). Based on survey data, an estimated 1 in 6 (18%) general practice visits in 2015–16 were for management of musculoskeletal conditions (Britt et al. 2016). See Primary health care.
People with musculoskeletal conditions that are very severe, or who require specialised treatment or surgery, can also be managed in hospitals. In 2017–18, there were around 795,000 hospitalisations for musculoskeletal conditions—7.1% of all hospitalisations in that year. These hospitalisations included:
Clinical guidelines in Australia recommend joint replacement surgery as a cost-effective intervention for people with severe arthritis who are unresponsive to medication and exercise (RACGP 2018). Osteoarthritis is the most common condition leading to hip and knee replacement surgery in Australia (AOANJRR 2019). Between 2008–09 and 2017–18, the rate of joint replacement surgery in hospitalisations where osteoarthritis was the principal diagnosis increased by 27% for total knee replacements and 33% for total hip replacements, after adjusting for age (AIHW 2019d).
The prevention, management and treatment of musculoskeletal conditions beyond hospital settings cannot currently be examined in detail due to limitations in available data on:
Among people aged 45 and over, the prevalence of musculoskeletal conditions generally increases with increasing socioeconomic disadvantage, but is similar across remoteness areas, after adjusting for age (Figure 6).
Among persons aged 45 and over, the prevalence of arthritis was higher in the lowest socioeconomic area (most disadvantaged, 41%) compared with persons in the highest socioeconomic area (least disadvantaged, 25%). The prevalence of arthritis was similar in Major cities (31%) compared with Remote areas (34%).
