This study aims to develop and demonstrate the effectiveness of a systematic, practical, cost-effective diet-induced weight loss and exercise intervention in Cherokee, North Caroling that will recruit American Indian participants; 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.
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.
Participants will be 30 ambulatory, community-dwelling, overweight and obese men 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 3-month diet-induced weight loss and exercise intervention implemented in Cherokee, North Carolina 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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Diet & Exercise | Experimental | Participants will attend an exercise class 3 days/week for 3 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 will be prescribed an individual walking prescription by the exercise leader, which will be adjusted accordingly, as each participant progresses throughout the 3 months. The exercise will be of moderate intensity. Alternate forms of aerobic exercise, such as but not limited to stationary bike, elliptical trainer, or treadmill walking, can be used in place of over-ground walking. This choice could be based on participant preference, the limitations of the exercise facility, or the participant's pain level. |
|
| Attention Control | Active Comparator | The attention control intervention will cover an 3 month period. There will be two face to face group meetings over the 3 months, with one meeting each at months 1 and 3; and during the other months (month 2) participants will receive a combination of text messages, emails, and phone calls based on continued monitoring of participant needs and delivered via their preferred mode of contact. |

| Behavioral Risk Factor Surveillance System (BRFSS) | The BRFSS is a cross-sectional telephone survey that measures health literacy - the nation's premier system of health-related telephone surveys that collect state data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. | Baseline and Month 3 |
| The Physical Activity Scale for the Elderly (PASE) | The PASE assesses the types of activities typically chosen by older adults (walking, recreational activities, exercise, housework, yard work, and caring for others. It uses frequency, duration, and intensity level of activity over the previous week to assign a score, ranging from 0 to 793, with higher scores indicating greater physical activity -Total PASE scores are computed by multiplying activity weights by activity frequencies | Baseline and Month 3 |
| The Montreal Cognitive Assessment (MOCA) | During the MOCA, a health professional asks a patient a series of questions designed to test a range of everyday mental skills. The maximum MOCA score is 30 points. A score of 20 to 24 suggests mild dementia, 13 to 20 suggests moderate dementia, and less than 12 indicates severe dementia | Baseline and Month 3 |
| Center for Epidemiologic Studies Depression Scale | The score is the sum of the 20 questions. Possible range is 0-60. If more than four questions are missing answers, do not score the Center for Epidemiologic Studies Depression (CES-D) questionnaire. A score of 16 points or more is considered depressed | Baseline and Month 3 |
| Cost-effectiveness | Resource utilization will be collected by questionnaire, with domains including visits to clinicians (physicians, nurses, physical therapists, others), tests, medications, injections, surgery, alternative therapies.
