Study Overview
Brief Summary
The goal of this study is to conduct a program of pilot research aimed at developing and evaluating a technology-assisted wellness intervention for older adults with obesity.
Detailed Description
The national epidemic of obesity is also affecting older adults, and is associated with an increased risk of disability, nursing home placement and early mortality. Conventional weight loss programs have the potential to reduce body fat, but are difficult to access for older obese adults due to transportation and mobility challenges. The overarching goal of this study is to conduct a program of pilot research aimed at developing and evaluating a technology assisted wellness intervention for older adults with obesity.
Study Timeline:
September 2018 to April 2021:
Goal: Conduct a study of improving weight and physical function in older adults with obesity at home using video-conferencing. An mHealth obesity wellness intervention (MOWI) will integrate a fitness device with a weekly individual dietician-led nutritional session, along with twice weekly physical therapist led group exercise session performed in a person's home.
Participation Duration: Three times weekly for 6 months. We shall also have participants return to the center once monthly

Arms & Interventions
Evaluate home-based MOWI
Conduct and assess the feasibility, acceptability, and potential effectiveness of home-based MOWI in improving physical function.
Intervention: Evaluate home-based MOWI (Behavioral)
Outcomes
Primary Outcomes
Change in 30 Second Sit-to-Stand (STS)
Time Frame: Change between baseline and follow-up at 26-weeks
STS measures lower limb strength - change represented as repetitions.
Change in Grip Strength
Time Frame: Change between baseline and follow-up at 26-weeks
Assessed by a Jamar dynamometer. Sensor-based Thera-bands will measure data on strength change.
Change in Gait Speed (Meters Per Second)
Time Frame: Change between baseline and follow-up at 26-weeks
Gait speed is measured by the time it takes to walk 20 meters. Gait speed predicts disability and mortality (a significant change is considered 0.1 meters per second).
Change in Late-Life Function and Disability Instrument (LLFDI)
Time Frame: Change between baseline and follow-up at 26-weeks
LLFDI consists of a 32-item function and 16-item disability (life-task) scales that correlate with gait speed and lower limb function. For this instrument we use only the 32-item function and scores are scaled. Minimum 0, Maximum 100. Higher scores indicate higher levels of function
Change in Six-Minute Walk Test (6MWT)
Time Frame: Change between baseline and follow-up at 26-weeks
A surrogate for cardiovascular fitness that measures distance (normal 400-700m) related to function. A clinically important difference is 50-55m
Secondary Outcomes
- Change in Body Mass Index (BMI) in kg/m^2(Change between baseline and follow-up at 26-weeks)
- Change in Waist Circumference in cm(Change between baseline and follow-up at 26-weeks)
- Community Healthy Activities Model Program for Seniors Physical Activity Questionnaire (CHAMPS) - Hours Per Week(Change between baseline and follow-up at 26-weeks)
- Change in Weight in kg(Change between baseline and follow-up at 26-weeks)
- Steps(Change between baseline and follow-up at 26-weeks)
- Behavioral Activation (Patient Activation Measure)(baseline and follow-up at 26-weeks)
- Subjective Health Status (PROMIS)(Change between baseline and follow-up at 26-weeks)
- Community Healthy Activities Model Program for Seniors Physical Activity Questionnaire (CHAMPS) -(Change between baseline and follow-up at 26-weeks)
- Community Healthy Activities Model Program for Seniors Physical Activity Questionnaire (CHAMPS) - Frequency Per Week(Change between baseline and follow-up at 26-weeks)
