A Nutrition Intervention for Arthritis -3 (WCCR-ARTH3)
|ClinicalTrials.gov Identifier: NCT03417648|
Recruitment Status : Completed
First Posted : January 31, 2018
Last Update Posted : March 4, 2019
The purpose of the study is to assess whether, in individuals with rheumatoid arthritis, a low-fat, vegan diet improves pain and other subjective symptoms more effectively than a control supplement or a placebo. The principal measure is pain as measured by Visual Analog Scale (VAS) and disease activity as measured by number of painful swollen and tender joints, respectively. The study duration is 36 weeks.
This study tests that a low fat, plant-based (vegan) diet free of foods commonly identified as triggers improves mood, using the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), and the Beck Depression Inventory II (BDI-II).

Experimental: Plant-based diet
The diet group will be asked to follow a low-fat, vegan diet for 16 weeks
Other: Plant-based diet
Weekly instructions will be given to the participants in the intervention group about following vegan diet.
Placebo Comparator: Supplement
The supplement group will follow an unrestricted diet, but will be given a pill containing a small, clinically insignificant amount of omega- 3 oils and vitamin E, which will serve as a placebo.
unrestricted diet with clinically insignificant amount of omega- 3 oils and vitamin E
Other Name: Vitamin E
- Pain Score [ Time Frame: Change in pain score from Baseline at 4 months ]will be measured by visual analog scale from 0%, indicating no pain, to 100%, indicating pain as bad as it could possibly be
- Disease Activity score [ Time Frame: Change in disease activity score from Baseline at 4 months ]measured by number of painful, swollen and tender joints
- Improvement in mood [ Time Frame: Change in mood from Baseline at 4 months ]measured by the Beck Depression Inventory II (BDI-II).
- Quality of Life [ Time Frame: Change in quality of life from Baseline at 4 months ]measured by a Modified Health Assessment Questionnaire (MHAQ). The questionnaire measures the difficulty level of performing 8 different activities. A score of 0 = the activity can be performed without difficulty. A score of 3 = the activity cannot be performed. The MHAQ is calculated as the average of these scores.
