An interventional study of Basic Lottery and Combined Lottery in Sedentary Employees, sponsored by University of Pennsylvania. Completed at 1 site in United States. Open to participants aged 18 Years to 100 Years. Per ClinicalTrials.gov, last updated 2019-03-05.
Sponsored by University of Pennsylvania · Not applicable, Interventional, and Other
Employers are increasingly looking for opportunities to motivate sedentary employees to become more physically active. Workplace walking programs have had mixed success and typically show most improvement among participants that are already fairly active at a baseline. The goal of this study is to determine whether a financial incentive program can motivate sedentary employees to increase the number of steps they walk per day to meet a minimum threshold.
Our primary outcome measure is the proportion of days a minimum activity of 7000 steps or more is achieved. We will assess outcomes each week for 3 months using incentives followed by 3 months of follow-up without incentives. Secondary outcomes will include the average steps walked per day.
University of Pennsylvania is the lead sponsor of 1,635 studies on the registry; 239 are open to participants now.
Of its 154 completed or terminated interventional studies of FDA-regulated products, 104 (68%) have results posted.
