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.

Research Highlights
How do employment support programs impact the health of young adults with episodic disabilities?
The unpredictable and often invisible nature of episodic disabilities can make it challenging for workers to find and sustain employment while managing their fluctuating symptoms and work demands. For young adults navigating early career phases, these challenges may also have life-long impacts on their career progression and health. Researchers on an IWH study set out to investigate whether employment support programs for young adults with episodic disabilities may also impact their health.
