AbstractObjectives We investigated the factors associated with the deterioration of the Health Assessment Questionnaire-Disability Index (HAQ-DI) over five years in patients with rheumatoid arthritis (RA). Methods Clinical data were obtained from 391 patients who were classified into 2 groups: a group with HAQ-DI deterioration (in which the HAQ-DI had worsened) and a group without HAQ-DI deterioration. A multivariable logistic regression analyses of the age, sex, disease duration, body mass index, anti-cyclic citrullinated peptide antibody, the use of biological disease-modifying antirheumatic drugs or targeted synthetic disease-modifying antirheumatic drugs, methotrexate use, glucocorticoid use, C-reactive protein, pain visual analog scale (pain VAS), disease activity score 28 erythrocyte sedimentation rate (DAS28-ESR), the HAQ-DI, and van der Heijde modified total Sharp score was performed at baseline and five years to determine significant factors associated with the HAQ-DI. Results The significant factors associated with HAQ-DI deterioration were age [odds ratio (OR): 1.05; 95% confidence interval (CI): 1.02-1.08], glucocorticoid use (OR: 1.95; 95% CI: 1.03-3.71), DAS28-ESR (OR: 1.92; 95% CI: 1.33-2.79), change in pain VAS from baseline (OR: 1.02; 95% CI: 1.01-1.04), and change in DAS28-ESR from baseline (OR: 1.67; 95% CI: 1.15-2.44). Conclusion The present study suggests that glucocorticoid tapering as well as disease activity and pain control are required to prevent deterioration of the HAQ-DI in patients with RA.
