The purpose of the present study was to assess components of sleep quality and self\u2010identified contributors to sleep fragmentation in rheumatoid arthritis (RA) and osteoarthritis (OA) patient populations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Consecutive RA and OA clinic patients were invited to participate in a self\u2010administered questionnaire study which included the validated multi\u2010domain Pittsburgh Sleep Quality Index (PSQI), visual analogue scales for pain, fatigue, global functioning, modified Health Assessment Questionnaire (mHAQ), stress scores, the Centre for Epidemiologic Studies\u2013Depression (CES\u2013D) score, the 36\u2010item short form (SF\u201036) quality of life measure, the Rheumatoid Arthritis Disease Activity Index (RADAI), the Epworth Sleepiness Scale (ESS), Berlin score for obstructive sleep apnoea (OSA) risk and the International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study population included 145 RA and 78 OA patients. PSQI global scores were &gt;5 in 62% of RA and 67% of OA patients. Multivariate analysis identified global functioning and the CES\u2013D to be independent predictors for higher global PSQI scores in RA patients, whereas in OA patients predictors were the mHAQ and SF\u201036 mental component summary. Abnormalities in subjective sleep assessment, sleep latency, sleep duration, sleep efficiency, daytime dysfunction and increased sleep\u2010aid medication use were observed in both populations. The most common abnormality reported by both RA and OA patients was increased sleep fragmentation. The most frequent self\u2010identified cause for sleep disturbance was \u2018need to use the washroom\u2019 by 51% of RA and 49% of OA patients, and, second most common, \u2018pain\u2019 was identified as a cause for awakening by 33% of RA and 45% of OA patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A high prevalence of abnormal sleep quality in both RA and OA patient populations was observed. The most common abnormality was sleep fragmentation, with an increased sleep disturbance score. \u2018Need to use the washroom\u2019 and \u2018pain\u2019 were the most common self\u2010identified reasons for awakening from sleep. A review of sleep hygiene, optimization of urological status, and rheumatological disease symptomatic control may prove beneficial in terms of sleep health.
