Background: Despite the known benefits of exercise 1 , patients with osteoarthritis (OA) and rheumatoid arthritis (RA) are reported to have low levels of physical activity 2 . Exercise participation is not well studied in psoriatic arthritis (PsA) cohorts. This study aims to explore which factors predict exercise participation across cohorts and specifically in the PsA cohort. Objectives: The primary aim of this study was to determine which clinical factors were predictive of self- reported physical activity levels in patients with PsA. A secondary aim was to explore differences in self-reported physical activity levels amongst patients with PsA, OA and RA. Methods: Patients with the diagnosis of PsA, RA or OA are recruited prospectively at two tertiary hospital rheumatology clinics over 12 months. Demographic data is captured by the multi-dimensional health assessment questionnaire, the international physical activity questionnaire short form captures self-reported physical activity and self-efficacy for exercise (SEE) is assessed using the SEE scale. Clinical data including joint count, body mass index and co-morbidities including fibromyalgia are collected for all patients, in addition to PsA specific data including skin and enthesitis indices. Results: 205 patients (PsA n=62, RA n=83, OA n=60) were recruited across two sites. There was no significant difference in self-reported physical activity between OA, RA and PsA cohorts. Fibromyalgia was present in 30% of each cohort. In patients with PsA, univariate analysis showed that co-existent fibromyalgia, age and self-efficacy for exercise were predictors of physical activity levels. Skin disease and enthesitis were not predictors of physical activity in the PsA cohort. Table 1. Univariate Analyses of effect of Clinical Features on Physical Activity levels in PsA Non-exercisers versus Exercisers OR (95% CI ) P-value LEI 1.35 (0.92-1.97) 0.127 PASI 0.8 (0.6-1.07) 0.133 DLQI 1.03 (0.92-1.16) 0.589 BMI 0.97 (0.91-1.04) 0.415 DAS28 0.79 (0.55-1.14) 0.205 Concurrent Fibromyalgia 4.46 (1.37-14.49) 0.012 Age 1.05 (1.00-1.10) 0.013 Self-efficacy for exercise 0.97 (0.95-0.99) 0.019 Pain 1.17 (0.99-1.37) 0.061 Function 1.3 (1.02-1.65) 0.031 Patient global 1.14 (0.96-1.34) 0.128 Depression 0.97 (0.51-1.84) 0.930 Table 2. Multivariable Analysis on Physical Activity in PsA Non-exercisers vs Exercisers OR (95% CI ) P-value Concurrent fibromyalgia 5.1 (1.44-18.08) 0.0117 Age 1.05 (1.00-1.11) 0.0342 Conclusion: In the PsA cohort, fibromyalgia and age were associated with lower levels of physical activity. DLQI, PASI, LEI did not predict physical activity in PsA. Multivariate analysis showed higher pain levels and lower self-efficacy scores were associated with lower physical activity across arthritis groups.
