Chronic conditions and work
Chronic conditions refer to diseases and health conditions that last a long time and generally progress slowly. Although they can occur at any age, they become more common later in life. They are often invisible, sometimes episodic (i.e. they come and go) and often characterized by fluctuating symptoms that leave people disabled one day and functional the next. Examples of chronic diseases include arthritis, diabetes, chronic pain, depression and fibromyalgia. IWH research in this area focuses on the effects of chronic disease on work participation and productivity, as well as the effectiveness of job accommodations, benefits and other programs to ensure workers with chronic disease can stay at, or return to, work.

Does it matter what workers’ reasons are for disclosing or not disclosing a disability at work? Why and how?
Deciding whether or not to disclose a disability to others at work is a complex consideration. People with many chronic mental and physical health conditions, often called episodic disabilities, experience times of relative wellness punctuated by intermittent periods of activity limitations. How do they decide whether or not to disclose their health conditions? In this presentation, Dr. Monique Gignac shares findings from her study examining participants' reasons and goals for disclosing—and whether these matter to work support outcomes.

Research Highlights
Depression and work among adults with arthritis
About 13 per cent of working-age people in the U.S. who have arthritis also experience depressive symptoms. Having both arthritis and depressive symptoms lowers the likelihood of working. For people aged 35 to 54, having depressive symptoms in addition to arthritis lowers the likelihood of working by 17 per cent.

Sharing Best Evidence
Work activities and the development of osteoarthritis in men and women
A systematic review by the Institute for Work & Health finds strong and moderate evidence that work exposures—including lifting, cumulative physical loads, full-body vibration and kneeling/squatting/bending—can increase the risks of osteoarthritis in men and women. No increased risk was found for sitting, standing and walking (hip and knee osteoarthritis); lifting and carrying (knee osteoarthritis); climbing ladders (knee osteoarthritis); driving (knee osteoarthritis); and highly repetitive tasks (hand osteoarthritis).
