Sleep Disturbance in Osteoarthritis: Linkages With Pain, Disability, and Depressive Symptoms

It is known that osteoarthritis (OA) increases the risk of sleep disturbance, and that both pain and sleep problems may trigger functional disability and depression. However, studies examining all 4 variables simultaneously are rare. The aim of this study was to examine cross‐sectional and longitudinal associations of self‐reported sleep disturbance with OA‐related pain and disability and depressive symptoms.
