Relationship between achievement of physical activity goal and characteristics of patients with rheumatoid arthritis

Abstract

Objectives: We aimed to identify the relationship between achievement of a physical activity goal and the characteristics of patients with rheumatoid arthritis (RA).

Methods: Overall, 137 patients with RA who performed physical activity were enrolled. Statistical analysis was performed to examine relationship between patient characteristics and achievement of physical activity goal by univariate analysis, multivariate logistic regression analysis and the receiver operating characteristic method.

Results: The significant factors considered for univariate analysis performed to compare RA patients with and without achievement in physical activity goal were age, disease duration, BMI, global VAS, pain VAS, CRP, DAS28-CRP, and HAQ-DI. The significant related factors by multivariate logistic regression analysis were age (OR: 0.926), BMI (OR: 1.180), pain VAS (OR: 0.969), and HAQ-DI (OR: 0.229). The cutoff values were 62.0 years for age (sensitivity 72.5%, specificity 59.6%), 19.7 for BMI (sensitivity 91.2%, specificity 36.2%), 20.0 for pain VAS (sensitivity 63.7%, specificity 71.9%), and 0.30 for HAQ-DI (sensitivity 48.8%, specificity 89.5%).

Conclusion: We aim to preserve activities of daily living in patients with RA. To achieve physical activity goal, we should control pain VAS, and HAQ-DI. Further, the patients the value of HAQ-DI should be kept very low.
