简要总结
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.
详细描述
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

结局指标
主要结局
Change in Grip Strength
时间窗: 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)
时间窗: 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 30 Second Sit-to-Stand (STS)
时间窗: Change between baseline and follow-up at 26-weeks
STS measures lower limb strength - change represented as repetitions.
Change in Late-Life Function and Disability Instrument (LLFDI)
时间窗: 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)
时间窗: 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
