We have had a paper published in the journal, PLoS One, showing that South Asian people were significantly more likely to experience objective and self-reported disability in older age than Europeans. This excess risk could not be explained by demographic, behavioural and chronic disease risk factors. In contrast, a reduced risk of the most severe measure of disability was observed in the African Caribbean group, compared with the European sample.
This is the first study in the UK to examine disability rates in different ethnic groups. We now need to develop our knowledge about the causes of disability across different groups and understand whether beliefs about healthy aging and functioning in older age contribute to these disability levels.
