Effect of Anti-inflammatory Diet in Osteoarthritis

October 31, 2024 updated by: Monica Guma, University of California, San Diego

An Evaluator-blinded Randomized Controlled Trial Study of the Effect of Anti-inflammatory Diet in Subjects With Osteoarthritis

In a previous exploratory study, the investigators observed an effect on disease activity outcomes of anti-inflammatory diet. The investigators also observed change in microbiome and circulating metabolites. The current study will determine whether or not the addition of anti-inflammatory diet improves the clinical outcomes in participants with Osteoarthritis, and the role of microbiome and circulating metabolites.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Knee Osteoarthritis Pain
Time Frame: 3 months
The Western Ontario and McMaster Universities Osteoarthritis Index, known as the WOMAC score, is a validated questionnaire used for evaluating pain, stiffness, and physical function in individuals with knee or hip osteoarthritis. A minimum score of 0 indicates no symptoms and a maximum score of 100, represents the most severe symptoms. Higher WOMAC scores correspond to worse outcomes, indicating more significant pain, stiffness, and functional limitations associated with osteoarthritis. The primary outcome for the purpose of this study will be the proportion of patients experiencing a change of at least 30% in WOMAC-pain score after 3 months of intervention compared to the control group.
