<h3>Background:</h3> Psoriatic arthritis (PsA) prevalence is equal in men and women, though gender may play a role in driving mechanisms of PsA leading to differences in manifestations of clinical disease (1). <h3>Objectives:</h3> Assess key differences in clinical characteristics, disability, quality of life, and work productivity by gender in real-world practice. <h3>Methods:</h3> Cross-sectional survey of rheumatologists and dermatologists and their patients in France, Germany, Italy, Spain, UK, and US. Data were collected from Jun-Aug 2018 via physician-completed patient record forms and patient self-completed forms. Data were analyzed by gender. Demographic characteristics, treatment use, and clinical characteristics (Tender Joint Count [TJC], Swollen Joint Count [SJC], Body Surface Area [BSA] psoriasis) were reported by physicians, while quality of life (EQ5D and PsAID12), disability (HAQ-DI), and work productivity (WPAI) were reported by patients. Men and women were compared using parametric tests and non-parametric tests where appropriate. <h3>Results:</h3> Data were collected for 2270 patients (595 US, 1675 Europe). Demographic characteristics, time from first symptoms to diagnosis, biologic treatment, and clinical characteristics were comparable between women and men (Table 1). More women reported worse quality of life, disability, and work activity impairment than men (Table 2). <h3>Conclusion:</h3> In women and men with similar PsA disease activity and treatment rates, women experienced worse quality of life, greater disability, and greater work impairment, despite a lower burden of comorbidities. <h3>Reference</h3> [1] Billi AC, Kahlenberg JM, Gudjonsson JE.
