To explore if the SARC-F questionnaire correlates with muscle strength, physical performance, and overall health in patients with spondyloarthritis.
Cross-sectional study design
Evaluated patient characteristics, physical function, and body composition using DXA
Compared SARC-F scores between Sarcopenia risk groups through linear regression
24.4% of patients had a SARC-F score ≥4, indicating higher sarcopenia risk
DXA identified sarcopenia in 4 patients (7.7%)
Patients with higher SARC-F scores showed lower muscle strength and physical performance
Moderate specificity (76%) and low sensitivity (50%) of SARC-F for DXA-defined sarcopenia
