Sleep disorders are common among patients with rheumatoid arthritis (RA), however, these disorders are not associated with disease activity and do not affect quality of life. This according to a study of 101 patients (mean age 48.7 years, 95% female) who attended a rheumatology clinic at a university hospital between October 2015 - May 2016. All patients were clinically examined and interviewed by physicians using a questionnaire. Researchers found:
- Approximately 60% of participants were in the remission/low category of disease activity.
- The prevalence rates of insomnia, excessive daytime sleepiness, sleep disturbance, risk of obstructive sleep apnea, and restless legs syndrome were 63%, 20%, 20%, 37%, and 63%, respectively.
- The distribution of sleep disorders was not affected by the disease activity.
