There are currently no known reported studies related to the prevalence, correlates, and impact of sleep disturbance in pSS patients from China. Therefore, this study aims to assess the sleep quality in Chinese pSS patients and evaluate its relationship with the disease activity, quality of life and mood disorders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A self\u2010report survey was administered to 221 pSS patients and 198 healthy individuals using the Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Disease activity and damage were evaluated with the European League Against Rheumatism Sj\u00f6gren's syndrome disease activity index (ESSDAI). Independent samples <jats:italic>t<\/jats:italic> tests, Chi\u2010square analysis, logistic regression were used to analyze these data.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Our results found that the prevalence of poor sleep (PSQI\u00a0\u2265\u00a06) was 57.5% and the mean global score of PSQI was 6.57 (SD 3.19) in patients, which were significantly higher than the controls (32.3% and 4.93 [SD 2.86], respectively). When trying to fall asleep, patients with pSS had some sleep disturbances, reduced sleep efficiency, increased number of awakenings than controls. There were significant correlations among dryness, ocular surface disease, HRQoL, pain, disease activity, anxiety\/depression and sleep quality in pSS patients. Meanwhile, logistic regression models identified depression and Short Form\u201036 mental composite score as predictors of poor sleep quality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Sleep disturbances are commonly reported in pSS patients and sleep quality is lower in pSS patients than in healthy controls.
