The Collaborative Lifestyle Intervention Program in Knee Osteoarthritis Patients: CLIP-OA

The Collaborative Lifestyle Intervention Program in Knee OsteoArthritis Patients (CLIP-OA) compares a novel community-based exercise and dietary weight loss program to the Arthritis Foundation's Walk with Ease intervention on improved mobility in knee osteoarthritis (OA) patients.

Gedetailleerde beschrijving

Knee OA is a chronic, progressive, degenerative disease that affects over 20 million Americans, and is cited as the primary cause for activity restriction and physical disability in older adults. The joint damage and symptoms (i.e., pain, stiffness, and fatigue) accompanying symptomatic knee OA result in activity restriction, muscle atrophy, reduced quality of life and difficulty in performance of functional tasks.

Despite the well-established benefits of the Arthritis Foundation's (AF) exercise programs, recent evidence suggests that lifestyle interventions combining Exercise and Dietary Weight Loss (EX+DWL) results in superior improvements in key clinical outcomes in older, overweight or obese knee OA patients.

Primary Aim: To compare the effects of a novel community-based EX+DWL program to AF's Walk with Ease (WWE) EX intervention on improved mobility in knee osteoarthritis (OA) patients.

Secondary Aim: To compare the cost effectiveness and effects of the EX+DWL and WWE interventions on weight loss, pain, and quality of life.

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Exercise and Dietary Weight Loss
For the first 6 months, participants will meet at a community center for 3 group-based sessions and 1 individual session each month. Sessions include a 45 minute exercise component and a 45 minute dietary weight loss component. Exercise will consist of progressive aerobic and strength training. The dietary component will focus on decreasing caloric intake, while being nutritionally safe. All diets will be monitored by a Registered Dietitian. During months 7-12, participants will meet for 1 group session and 1 individual session per month. The final 12-24 months, bimonthly phone calls are provided to the participants to aid in retention efforts.
Gedragsmatig: Exercise and Dietary Weight Loss
The EX+DWL intervention consists of group and individual exercise sessions, as well as, nutritional and dietary counseling. Bimonthly phone calls are made in the final year of the study to aid in maintenance of the program.
Actieve vergelijker: Walk with Ease
The Arthritis Foundation's (AF) WWE is a self-management program for symptoms of arthritis (pain, fatigue, stiffness,etc.) through exercise. It is a 6 week program involving 3 sessions per week each lasting about 60 minutes. The WWE sessions are comprised of walking, stretching and strengthening exercises, and health education lectures. These group classes will be lead by an AF instructor. Each participant will complete 2 consecutive WWE classes for a total of 12 weeks in the program. During the final week of the program, participants will be trained and transitioin to the self-directed version of WWE for maintenance of exercise. To aid in retention efforts, phone contacts are provided to participants on a monthly basis from 4-12 months and bi-monthly from 12 to 24 months
Gedragsmatig: Walk with Ease
The WWE 6 week program consists of health education lectures on arthritis self-management, a walking exercise portion, and at- home strength exercises. Participants will complete two consecutive WWE programs. Monthly and bimonthly phone calls are made to participants in months 4-12 and 12-24, respectively, to aid in maintenance of the program.

Wat meet het onderzoek?

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Mobility Disability
Tijdsspanne: baseline up to 2 years
This will be assessed using the 400 meter walk test (400MWT), which is the time to complete 400m as quickly as possible (without running)
baseline up to 2 years

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Anthropometric Battery
Tijdsspanne: baseline up to 2 years
Body weight and height are used to calculate Body Mass Index (BMI). Body composition will be assessed using DEXA scans.
baseline up to 2 years
Functional Battery and Limitations
Tijdsspanne: baseline up to 2 years
Stair-climb time (SCT) is a functional performance measure that involves ascending and descending a flight of 5 stairs as quickly as possible. Limitations will be assessed using the Pepper Assessment Tool for Disability.
baseline up to 2 years
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Tijdsspanne: baseline up to two years
Scale of 0 (none) to 4 (extreme) indicating the amount of difficulty they have experienced performing basic physical function tasks in the past 48 hours due to knee OA. The physical function subscale consists of 17 items that will be summed to produce a physical function score. Higher scores indicating poorer function
baseline up to two years
Rand Medical Outcomes Study 36-item Short Form Health Survey (SF-36)
Tijdsspanne: baseline up to two years
Health related quality of life survey consisting of mental and physical health with subscales of physical functioning, mental health, role-physical, role-emotional, bodily pain, general health, vitality, and social functioning
baseline up to two years
Dietary intake
Tijdsspanne: baseline up to two years

Cost effectiveness
Tijdsspanne: baseline up to two years
The cost-effectiveness of the EX+DWL intervention compared to the WWE [program will be calculated as the ratio of additional cost per participant per increment of effectiveness. Effectiveness is based on improvement in the 400 MWT and the Quality of Well-being Scale- Self Administered (to calculate the Quality Adjusted Life Years).
