Poor Sleep Quality is Associated with Greater Rheumatoid Arthritis Disability

A study has determined that poor sleep quality is correlated with higher levels of depressive symptoms, greater pain severity, increased fatigue, and greater functional disability in patients with rheumatoid arthritis (RA).

Participants in the study completed questionnaires that provided input on their sleep quality and symptoms, and patients also provided sociodemographic information and their medical history. According to the results, 61 percent of patients were poor sleepers and 33 percent reported having pain that disturbed their sleep three or more times per week.

Eurekalert reports:

“The study's finding that poorer sleep quality is associated with greater pain severity is consistent with recent evidence suggesting that sleep disruption may lower pain threshold and enhance pain in RA and otherwise healthy adults.”
