Spondyloarthritis & psoriatic arthritis
Dietary intake is related to disease activity and inflammation in radiographic axial spondyloarthritis: a cross-sectional multi-regional study
Authors' conclusion
Patients with r-axSpA report lower dietary quality compared with controls. Dietary intake is related to disease activity and inflammation.
Study context
- Population
- Patients with radiographic axial spondyloarthritis (r-axSpA) in northern and south-western Sweden and matched SCAPIS controls155 patients matched to 604 controls
- Participants
- 295 vs 604
- Exposure
- Patients with r-axSpA vs matched SCAPIS controls (dietary intake); dietary nutrients vs ASDAS and C-reactive protein (CRP) in patients
- Patientsn = 295
- Controlsn = 604reference
- Outcome
- Relationship between dietary intake (MiniMealQ food frequency questionnaire) and disease activity (ASDAS) and inflammation (CRP); dietary intake in patients vs controls
Methodological detailsmulti-regional, matched on sex, age, and geographical location, conditional logistic regression
- Multi-regional
- Matched on sex, age, and geographical location
- Conditional logistic regression
Main finding
As reported in the abstract
Dietary intake, patients vs controls, and association with ASDAS and CRP
- Patients had lower dietary fibre density and lower intake of marine omega-3 fatty acids, calcium, folate, iodine, phosphorus, potassium, selenium, vitamins A, C, and K, β-carotene, and alcohol
- Low intake of marine omega-3 fatty acids associated with higher ASDAS
- Lower dietary fibre density associated with elevated CRP
Observational data: associations, not effects.
