Objectives: The aim was to explore the prevalence and independent risk factors for anxiety and depression in RA patients and to assess the consistency between the hospital anxiety and depression scale (HADS) and Zung's self-rating anxiety scale/depression scale (SAS/SDS).
Methods: In total, 160 RA patients and 60 healthy controls (HCs) were enrolled consecutively, and HADS and SAS/SDS were completed.
Results: The HADS-defined anxiety rate, HADS-defined depression rate, SAS-defined anxiety rate and SDS-defined depression rate were 36.9, 36.3, 29.4 and 29.4%, respectively, in RA patients, all of which were much higher in RA patients than in HCs (all P < 0.001). A relatively high consistency was observed between HADS-defined anxiety and SAS-defined anxiety (κ = 0.551, P < 0.001) and between HADS-defined depression and SDS-defined depression (κ = 0.563, P < 0.001) in RA patients. Interestingly, screened by multivariate logistic regression analyses, single/divorced/widowed marital status, swollen joint count, disease duration, ESR, physician's global assessment (PhGA) and DAS28 were independently correlated with HADS-defined or SAS-defined anxiety risk in RA patients; meanwhile, female biological sex, single/divorced/widowed marital status, rural location, disease duration, PhGA and DAS28 were independently associated with HADS-defined or SDS-defined depression risk in RA patients.
Conclusion: Anxiety and depression are highly prevalent in RA patients and are independently correlated with single/divorced/widowed marital status and higher disease activity. In addition, the HADS presents a high consistency with the SAS/SDS with many fewer questions, which might be more suitable for long-term assessment of RA.
