%X To describe health-related quality of life (HRQOL) and physical function in patients with early axial spondyloarthritis (SpA) and to assess their associations with disease activity and radiographic damage. This was a cross-sectional study drawing upon baseline data of axial SpA patients (Assessment of SpondyloArthritis international Society criteria) from the ESPERANZA cohort. Linear regression analyses were used to evaluate the associations between disease activity and radiographic damage (spine and sacroiliac joints) with HRQOL, physical function, and spinal mobility. In total, 259 patients were included. The mean ± SD age was 32.2 ± 6.9 years, disease duration was 13.3 ± 6.8 months, Ankylosing Spondylitis Quality of Life score was 5.9 ± 4.8, Bath Ankylosing Spondylitis Functional Index score was 2.4 ± 2.3, Bath Ankylosing Spondylitis Metrology Index score was 1.4 ± 1.3, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score was 3.8 ± 2.3, C-reactive protein (CRP) level was 9.7 ± 13.2 mg/liter, and Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI-s) score was 1.7 ± 1.6. HRQOL was mainly associated with disease activity on univariate analysis (β values for BASDAI 0.646, patient global visual analog scale [VAS] 0.641, night back pain VAS 0.598, physician VAS 0.560, and CRP level 0.275; P  Patients with axial SpA already have impaired quality of life and physical function, albeit mildly, at the beginning of their disease course. Both outcomes are mainly associated with disease activity in these patients.
