What does this research mean for the field?

Factors associated with physical activity differ between rheumatoid arthritis and systemic lupus erythematosus, with comorbid fibromyalgia significantly reducing physical activity in RA patients. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To identify and compare shared and disease-specific clinical, functional, and psychological factors associated with physical activity levels in patients with rheumatoid arthritis and systemic lupus erythematosus.

Overview

Cross-sectional study uncovers distinct drivers of physical activity in rheumatoid arthritis and systemic lupus erythematosus, highlighting the need for disease-specific exercise strategies.

Key Points

To identify and compare shared and disease-specific clinical, functional, and psychological factors associated with physical activity levels in patients with rheumatoid arthritis and systemic lupus erythematosus.
Cross-sectional study analyzing 200 patients with rheumatoid arthritis and 94 with systemic lupus erythematosus recruited from a German university rheumatology outpatient clinic.
Physical activity was evaluated using the International Physical Activity Questionnaire Long Form alongside patient-reported outcomes for quality of life, comorbidities, and objective walking performance.
Multivariable logistic regression models were constructed to determine independent predictors of physical activity in each disease cohort.
Patients with rheumatoid arthritis had lower physical performance (p < 0.001) but achieved higher physical activity levels than those with systemic lupus erythematosus (p < 0.001).
Fibromyalgia was the sole independent predictor of lower physical activity in rheumatoid arthritis (OR = 0.001, 95% CI <0.001–0.289; p = 0.017), whereas no independent predictors were identified in systemic lupus erythematosus.
Self-reported physical activity moderately correlated with objective walking performance in both cohorts (rheumatoid arthritis: R² = 0.19; systemic lupus erythematosus: R² = 0.12).
