Background: Psoriatic Arthritis (PsA) is classified in the group of spondyloarthritides, which can involve axial involvement, peripheral arthritis, enthesitis, psoriatic lesions, and, like all spondyloarthritides, uveitis or chronic inflammatory bowel diseases. It is a chronic inflammatory disease with highly variable presentation, leading to functional and psychological impairments, with a significant negative impact on the quality of life of patients, notably a marked deterioration in sleep quality. Therefore, understanding the patient's perception of their health is of fundamental importance to grasp the real impact of Psoriatic Arthritis. In this context, the European League Against Rheumatism (EULAR) has recently developed an instrument specifically assessing the impact of PsA on the patient (PsAID), comprising 12 items, including anxiety, sleep disturbances, and pain. Objectives: Our study aimed to assess the frequency of sleep disorders and explore their determinants in patients with psoriatic arthritis. Methods: A descriptive cross-sectional retrospective study including 90 patients meeting the Classification Criteria for Psoriatic Arthritis (CASPAR). Sleep was self-assessed using the numerical scale (0–10) 'sleep' from the PSAID-12 questionnaire. Sleep disorders were defined by a numerical scale ≥ 4. Demographic and clinical variables associated with sleep disorders were assessed through univariate analysis and Poisson regression to estimate the prevalence ratio (PR). Results: We included 90 patients with confirmed Psoriatic Arthritis (PsA). The mean age was 44.6 years 17-85, with a female predominance of 58.4%. The average disease duration was 5.42 years. Among our patients, 4.4% were on biologic therapy, 36.7% had psoriasis covering less than 5% of body surface area, and 2.2% had a family history of psoriasis. The median self-reported sleep quality score was 6 (2–9), with 88.9% of our patients experiencing sleep disorders. In the Poisson regression model, patient-reported anxiety (PR: 1.11 1.03–1.20, p Conclusion: Sleep quality is a domain often overlooked despite significant degradation observed in patients with Psoriatic Arthritis (PsA). Sleep disorders were present in 88% of patients in our study. Unlike inflammation, pain, and anxiety were associated with sleep difficulties. We believe it is important to establish a systematic assessment of sleep quality, and further studies will be necessary to identify therapeutic strategies capable of improving the sleep of patients with Psoriatic Arthritis.
