Obesity is a modifiable risk factor for knee osteoarthritis (OA), and weight loss is an effective non-pharmacologic treatment to reduce pain. Recently, the investigators determined that under ideal, highly controlled circumstances, a diet-induced weight loss of 10% combined with exercise was significantly better at reducing pain than either intervention alone. Compared to the investigators previous longterm weight loss and exercise trials of knee OA, the diet-induced weight loss and exercise group was twice as effective at relieving pain. Whether the investigators results can be generalized to less rigorously monitored patient cohorts is unknown. Thus the challenge the investigators now face is to provide the practical means to implement this proven treatment in the community setting. This study aims to develop and demonstrate the effectiveness of a systematic, practical, cost-effective diet-induced weight loss and exercise intervention in both urban and rural communities that can reduce pain and improve other clinical outcomes in knee OA patients. This pragmatic community-based trial will determine if the investigators previous findings translate to real-world settings and will address common concerns about barriers to effectiveness/ implementation.
Participants will be 820 ambulatory, community-dwelling, overweight and obesemen and women who meet the American College of Rheumatology clinical criteria for knee OA. The primary aim is to determine whether a pragmatic, community-based 18-month diet-induced weight loss and exercise intervention implemented in three North Carolina counties with diverse residential (from urban to rural) and socioeconomic composition significantly decreases knee pain in overweight and obese adults with knee OA relative to an attention control group. Secondary aims will determine whether this intervention improves self-reported function, health-related quality of life, and mobility. The investigators will also establish the cost-effectiveness of this pragmatic, community-based, multimodal diet-induced weight-loss and exercise program by conducting cost-effectiveness and budgetary impact analyses using data from the current trial in a validated computer-simulated model of knee OA.
Many physicians who treat people with knee OA have no practical means to implement weight loss and exercise treatments. This study is significant in that it will test the effectiveness of a long-awaited and much needed community-based program that will serve as a blueprint for clinicians and public health officials in both urban and rural communities to implement a weight loss and exercise program designed to reduce knee pain and improve other clinical outcomes in overweight and obese people with knee OA that can be sustained long-term and at a reasonable cost.

|Masking:||Single (Outcomes Assessor)|
|Official Title:||Weight Loss and Exercise for Communities With Arthritis in North Carolina|

Experimental: Diet & Exercise
Participants will attend an exercise class 3 days/week for 18 months. The exercise program will consist of a 15-minute aerobic phase, a 20-minute strength training phase, a second 15-minute aerobic phase, and a 10 minute cool down phase. Participant's will also attend individual and group diet sessions. Each participant's minimum weight loss goal will be 10% of baseline body weight.
Behavioral: Diet & Exercise
Participants will attend exercise and diet classes.
Active Comparator: Attention Control
The attention control intervention will cover an 18-month period. There will be four total face to face group meetings over the 18 months, with one meeting each at months 1, 6, 12, and 18; and during the other months (months 2-5, 7-11, 13-17) participants will receive a combination of informational packets, webinars, and/or emails based on continued monitoring of participant needs and delivered via their preferred mode of contact.
Behavioral: Attention Control
Participants will attend healthy living classes and receive health newsletters and phone calls/emails/texts.
- Knee pain in overweight and obese adults with knee Osteoarthritis compared to an attention-control group measured by WOMAC Pain Scale. [ Time Frame: 18 months ]
- Knee function in overweight and obese adults with knee Osteoarthritis compared to an attention-control group measured by WOMAC Function Scale. [ Time Frame: 18 months ]
- Health Related Quality of Life in overweight and obese adults with knee Osteoarthritis compared to an attention-control group measured by SF-36. [ Time Frame: 18 months ]
- Mobility in overweight and obese adults with knee Osteoarthritis compared to an attention-control group measured by six minute walk. [ Time Frame: 18 months ]
- Measurement of the cost-effectiveness of the implemented strategies for the diet/exercise intervention and budget impact analysis. [ Time Frame: 18 months ]The cost-effectiveness ratio provides a measure of value for money. The cost-effectiveness is measured in dollars per quality-adjusted life-year gained ($/QALY). The budget impact analysis will quantify the financial consequences of adopting the program by various payer models, including insurance organizations, healthcare systems, and government, given real-life resource constraints
