The chronic diseases covered on this web site can limit the ability of people who have them to take part in normal activities of daily living. For example, arthritis often results in impairment of the mobility of joints or bones and asthma the function of the lungs. People who suffer from depression may be unable to relate effectively with others, while those who have had a stroke may need others to help them with daily activities such as bathing and grooming. It is now recognised that the concepts of functioning and disability involve a range of body impairments and activity limitations.
Information on disability in Australia comes from a variety of sources, the most prominent of which are the ABS National Surveys of Disability, Ageing and Carers. These surveys not only provide information on the extent of disability but also help identify diseases and conditions that contribute to this disability.
According to the 2003 survey, 3.9 million Australians, or 20% of the population, had a disability. Among those with a disability, 1.1 million (27% of all people with a disability) had one of the chronic diseases or conditions covered on this web site as their main disabling condition.
Arthritis and related disorders were on top of the list (Figure 1). More than 560,000 Australians (14% of all people with a disability) reported arthritis and related disorders as their main disabling condition, resulting in restricted mobility from severe joint pain.
Asthma (121,000) and depression (99,000) were the second and fourth most common of the conditions related to disability, often resulting in reduced attendance at school or work. Stroke (108,000) was another common condition among people with disability, with up to 75% of sufferers needing assistance with self-care, mobility or communication.
