Strength of associations of psoriatic arthritis and physical activity with body composition: the population-based Trøndelag Health study
To examine the associations of Psoriatic Arthritis (PsA) and physical activity (PA) with body composition, specifically visceral fat mass and percentage body fat, comparing individuals with PsA to controls.
Approach:
Study Design: Cross-sectional study utilizing data from the fourth survey of the Trøndelag Health study (HUNT4) in Norway.
Psoriatic Arthritis Diagnosis: Diagnosis of PsA validated using medical records and CASPAR criteria.
Physical Activity Assessment: Self-reported PA assessed through questionnaires and device-measured PA using accelerometers.
Key Findings:
Individuals with PsA have higher visceral fat mass and percentage body fat compared to controls.
Higher levels of self-reported PA correlate with lower visceral fat mass and percentage body fat in individuals with PsA.
Individuals with PsA engage in lower levels of PA compared to the general population.
Interpretation:
The study aims to clarify the contributions of PsA and PA to changes in body composition.
Limitations:
Cross-sectional design limits causal inferences.
Self-reported PA may be subject to bias.
Conclusion:
Understanding the relationship between PsA and PA may provide insights into body composition changes.
