An interventional study of MapTrek in Sedentary Behavior, sponsored by University of Iowa. Completed at 1 site in United States. Open to participants aged 25 Years to 100 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-05-15.
Sponsored by University of Iowa · Not applicable, Interventional, and Prevention
Older adults are a growing population, with projections to reach 83.7 million by 2050. Furthermore, older adults are the most sedentary and least physically active adult population. It is estimated that nearly 90% of older adults 65 years of age or older do not meet the recommended levels of physical activity. Evidence suggests great health benefits can be achieved for older adults who are the most sedentary, and that replacing sitting with even light intensity walking can be beneficial.
The overarching goal of the project is to develop an inexpensive and scalable tool to increase volume of physical activity in our target population, older adults living in a residential facility. MapTrek is a web-based application that allows participants to take a virtual walk in interesting locations around the world while tracking their progress against the progress of other older adults living in a retirement community. Steps are counted using a commercially available accelerometer (e.g., Fitbit), and participants see their progress overlaid on Google Maps.
All participants will be provided with a Fitbit activity monitor and instructed to wear it 24 hours/day (except for bathing/swimming time) on their wrist for 12 weeks. Participants will participate in four team-based walking races, each two weeks long. Participants will view their team progress on TV monitors placed in various locations at the Oaknoll facility. The Oaknoll leadership has given the research team approval to do this at their facility. The monitors will present aggregated team data and will not report any individual data that could link back to the individual participant.
At the end of the 8 week active intervention, research team members will meet with participants at Oaknoll to administer an exit/process evaluation survey. The exit survey will ask about psychosocial predictors of physical activity as well as participants thoughts and opinions of the MapTrek game. This survey should take approximate 10-15 minutes to complete. The participants will then be asked to wear the Fitbit for four more weeks without playing MapTrek, which will act as a control condition since this is a single-arm study.
The specific aims of the study are:
University of Iowa is the lead sponsor of 276 studies on the registry; 35 are open to participants now.
Of its 44 completed or terminated interventional studies of FDA-regulated products, 39 (89%) have results posted.

Exclusion Criteria:
Behavioral: MapTrek
Participants will receive a Fitbit activity monitor and access to the MapTrek game which will be visible on monitors set up in the residential facility.
Physical Activity
Daily steps
Time frame: 8 weeks
Self-efficacy
Self-efficacy was measured with the Self-Efficacy for Exercise scale, a 13-item questionnaire designed to assess participants' self-efficacy related to their ability to continue exercising in the face of barriers.
Time frame: 8 weeks
Social Support
Social support for physical activity was measured with a modified version of the Social Support and Exercise Survey. The Social Support and Exercise Survey is a 12-item (originally 13 item) questionnaire that assesses the level of support from family and friends that participants have in making health behavior changes (exercise)
Time frame: 8 weeks
Outcome Expectations
Outcome expectations were measured with the Outcome Expectations for Exercise Scale. The Outcome Expectations for Exercise is a valid and reliable 9-item scale that assesses the participant's outcome expectations and benefits associated with exercise.
Time frame: 8 weeks
Social Isolation
Social isolation was measured with a modified version of the Friendship Scale. The Friendship Scale is a 5-item (originally 6-item) scale that assesses 6 dimensions contributing to social isolation
Time frame: 8 weeks
Participants were recruited from June 17, 2019 to June 27, 2019, by word of mouth and through advertisements posted on digital monitors located throughout the retirement community.
