Depressive symptoms were significantly more prevalent in Brazilian patients with rheumatoid arthritis compared to German patients (44% vs 22.9%, p=0.025).
Cross-Sectional (n=267)
Yes
Depressive symptoms are highly prevalent in rheumatoid arthritis patients, varying by country, and are associated with pain, physical limitation, and inflammation.

OBJECTIVE: To investigate the prevalence of depressive symptoms and its association with clinical and psychological factors in patients with rheumatoid arthritis (RA) in Germany and in Brazil. METHOD: A convenience sample of 267 RA patients, 176 from Germany (age 62.4 ± 12.3 years) and 91 from Brazil (age 56.3 ± 12.6 years), was used in this cross-sectional study. The following questionnaires were used: Beck Depression Inventory (BDI), painDETECT test, Perceived Stress Questionnaire, fatigue questionnaire (FACIT), Health Assessment Questionnaire Disability Index (HAQ-DI), and the SF-36 questionnaires (Short-Form 36 Health Survey). Disease activity score (DAS 28-CRP) and visual analogue scale (VAS) for pain were also evaluated. Statistical analysis is based on comparison of means and proportions. Statistical significance for non-normal data was evaluated by non-parametrical tests. RESULTS: Depressive symptoms were more prevalent in the Brazilian sample (44% vs 22.9%, p = 0.025). Compared to German patients, the Brazilian ones also experienced more pain (current pain status on VAS: 4.67 ± 3.4 vs 3.67 ± 2.31 respectively, p < 0.01), were physically more limited (1.89 ± 1.85 vs 1.01 ± 0.75, p = 0.012), and had higher C-reactive protein levels (7.78 ± 18.3 vs 5.82 ± 10.45, p = 0.028). Despite receiving a more intensive treatment, German patients presented similar disease activity when compared to Brazilian patients (DAS28-CRP: Brazil 3.4 ± 1.5 vs Germany 3.3 ± 1.3, p = 0.307). CONCLUSION: Depressive symptoms are frequent in RA patients from different countries and interact with psychological disorders and the experience of pain. They contribute negatively to their well-being suggesting the need for psychoeducational strategies. Key Points • New psychoeducational strategies for RA management.• Higher inflammation marker in rheumatoid arthritis patients is associated with depression.• Medical treatment in RA influences depressive symptoms.• Depressive symptoms are dependent on population group.• High disease activity is related to depression.
Morf et al. (Mon,) conducted a cross-sectional in Rheumatoid arthritis (n=267). Brazilian residence vs. German residence was evaluated on Prevalence of depressive symptoms (p=0.025). Depressive symptoms were significantly more prevalent in Brazilian patients with rheumatoid arthritis compared to German patients (44% vs 22.9%, p=0.025).
