The Arthritis, Diet, and Activity Promotion Trial

Not Applicable
Completed
Conditions
Knee Osteoarthritis
Registration Number
NCT00979043
Lead Sponsor
Wake Forest University Health Sciences
Brief Summary

The primary purpose of this study was to determine the effect of dietary weight-loss, exercise training, or a combination of both on physical function in overweight and obese adults with knee osteoarthritis (OA). In secondary analyses, the effect of weight-loss and/or exercise on OA progression, self-reported pain and inflammation were examined. In post-trial analyses, the effect of dietary weight-loss on total mortality was determined.
