Fatigue and associated factors among patients with systemic lupus erythematosus in China: a cross-sectional study

The prevalence of fatigue in SLE was 58.7%. Fatigue was associated with monthly household income, educational level, depression, illness perception, pain, social support, sleep quality, and physical activity. No significant association was observed between anxiety, disease activity, age, work status, and fatigue. Future fatigue management for SLE patients should prioritize modifiable non-disease-activity-related factors.
