Understanding the relationship between osteoarthritis and work: a systematic review

Reasons for the study

Arthritis is among the most prevalent chronic health problems in Canada. It is estimated to affect more than 4.4 million people, which makes it the leading cause of physical disability in Canadian adults. Although often thought of as a disease of aging, about 60 per cent of people with arthritis are under age 65, with most being in their prime earning years (ages 45+). As a result, costs for arthritis are high. In 2000, the estimated burden of the disease in Canada was $6.4 billion per year, with two thirds ($4.3 billion) being indirect costs largely related to productivity losses and long-term disability. Osteoarthritis (OA) is the most common type of arthritis and ranks among the top ten causes of disability world-wide. Of increasing interest are personal and environmental factors that may contribute to the development of OA or aggravate its trajectory over time, particularly the role of occupational activities. This systemic review examined the research evidence to see if there is an association between OA and work.
