Ageing and fitness to work.

Ageing workers can be found in almost all occupations. Assessment of fitness to work in these workers is important, as it aims to match their functional capacity (which is reduced compared to younger workers), to the demands of their work (which may remain the same as that for younger workers). This outcome of assessment is influenced by the interaction between functional capacity, state of health, the nature of work, and possibilities for work accommodation. The assessment of functional capacity should include physical, mental and social capacity, as well as assessment of any disability. In addition to clinical or laboratory measurements, several authors have suggested the use of a 'work ability index' for specific occupations as a practical means of selecting the appropriate worker for the job. This index can also be used for monitoring functional capacity. In addition, as for any fitness to work assessment, a good understanding of the nature of the work and the work environment is required, and possibilities for work accommodations considered. While changes in the work environment and working conditions can be made to suit the functional capacity of the ageing worker, the maintenance of functional capacity is another important issue. There is a place for a greater role for disease screening and health promotion for such workers.
