Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
As individuals age, their physical activity decreases and sedentary time increases. Even small changes in these two behaviors can greatly decrease risks for several major health problems, including cardiovascular disease, diabetes, and many cancers. Studies that use pedometers to encourage walking have successfully increased physical activity, but do not address sedentary behaviors such as television watching. The investigators propose to use a novel pedometer-like device (Jawbone Up) that encourages both increased physical activity and decreased sedentary time. First, the investigators will recruit 10 adults to participate in a brief intervention for six weeks. They will wear the wrist-based activity monitor and use a mini-tablet device to see feedback on their activity and sedentary time. They will also receive brief counseling weekly. The investigators will use this first study to investigate the basic feasibility of the intervention materials. Next, the investigators will recruit 20 adults and randomize them to receive the intervention for 12 weeks or to a waiting list. Here, the investigators will test the intervention with refinements made based on participant responses from the first small study. Our primary outcomes will be measures of feasibility and acceptability across all parts of the study. The investigators hypothesize that the intervention will be feasible and acceptable to the participants. The investigators will also measure physical activity, sedentary behavior, fitness, body fat, and psychological feelings of motivation.
