Differential Predictors of Nighttime and Daytime Sleep Complaints in Older Adults with Comorbid Insomnia and Osteoarthritis Pain

摘要

ObjectivesOsteoarthritis (OA) is extremely common in older adults, affecting 50% of people aged 65 or older, and more than half of older adults with OA complain of significantly disturbed sleep. This study compared predictors of nighttime sleep complaints and daytime sleep-related consequences as measured by the Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) in older adults with comorbid OA pain and insomnia.
