Physical Activity in Patients With Rheumatoid Arthritis Treated With Adalimumab in Routine Clinical Practice

Completed

Conditions: Rheumatoid Arthritis

Registration Number: NCT01756235

Lead Sponsor: AbbVie (prior sponsor, Abbott)

Brief Summary: The purpose of this study was to evaluate physical activity and its changes in participants with rheumatoid arthritis (RA) who were treated with adalimumab therapy in clinical practice.

Detailed Description: This post-marketing observational study was conducted in a multi-country, multi-center and single-arm format. Data were collected prospectively. Adult participants with diagnosis of RA who were assigned for treatment with adalimumab (Humira®) were eligible for participation. During this period four follow-up visits were planned for observation of the participant and documentation of data. Ideally, these visits should have been performed approximately 3 (V1), 6 (V2), 9 (V3) and 12 (V4) months after the baseline visit (V0).

Mean Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) Score	Month 3, Month 6, Month 9, Month 12 and Month 12 LOCF	The Health Assessment Questionnaire - Disability Index (HAQ-DI) is a patient-reported questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores range from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from baseline in the overall score indicates improvement.
Correlation Between Physical Activity (Total SQUASH Score and Individual Physical Activity Categories' SQUASH Scores) and DAS28 Scores	Month 0 and Month 12 LOCF	The SQUASH and its subscores are instruments to measure the physical activity level, whereas the DAS28 measures disease activity. In order to evaluate the relationship between physical function and disease activity (as measured by the two scales), Pearson correlation coefficients were calculated for the SQUASH scores and the DAS28. A decrease in physical functioning is likely to be connected to stronger disease activity.
Correlation Between Physical Activity (Total SQUASH Score and Individual Physical Activity Categories' SQUASH Scores) and HAQ-DI Scores	Month 0 and Month 12 LOCF	The SQUASH and its subscores are instruments to measure the physical activity level, whereas the HAQ-DI measures physical functioning. In order to evaluate the relationship between physical function and physical activity (as measured by the both scales), Pearson correlation coefficients were calculated for the SQUASH scores and the HAQ-DI. A decrease in physical functioning is likely to prohibit physical activity.
