BACKGROUND: The recurrent nature and prolonged course of ankylosing spondylitis (AS) impose substantial psychological disorders on patients. The aim of this study was to assess psychological disorders and analyze the overall risk of psychological disorders as well as the factors associated with depression, anxiety, and stress in ankylosing spondylitis. METHODS: Patients diagnosed with AS were selected from the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) database for data analysis. General demographic characteristics and disease-related features of the patients were collected. The study analyzed clinical differences between patients with and without psychological disorders. Specific clinical characteristics of depression, anxiety, and stress were statistically analyzed. Clinical factors associated with overall psychological status and specific psychological disorders (depression, anxiety and stress) were analyzed by multivariate logistic regression. RESULTS: In our study cohort, 26.72% of AS patients were identified with psychological disorders, with 17.5% experiencing depression, 21.1% suffering from anxiety, and 7.9% reporting stress. We also observed significant overlaps among depression, anxiety, and stress in AS patients, with 53.47% experiencing multiple psychological disorders. Disease activity, health index, fatigue levels, and PGA were identified as significant factors associated with psychological disorders. Age, health index, fatigue levels, and PGA were the main influencing factors for depression
disease activity and PGA for anxiety
and disease activity, ASAS-HI, and fatigue for stress. CONCLUSIONS: The study reveals a significant prevalence of psychological disorders among individuals with AS, which correlates closely with disease activity, health index, fatigue levels, and PGA. These findings highlight the imperative for assessment of psychological conditions into the comprehensive management approach for AS patients.
