Primary outcomePrimary: Change in Mean Daily Step Counts During the 12 Month Intervention Using a Wearable Pedometer (Fitbit Watch) to Measure Step Count. — 1418; 1954; 1915; 2297 Step counts
Summary
The objective of this study is to use a randomized, controlled trial to test the effectiveness of using gamification, financial incentives, or both to increase physical activity among patients with elevated risk for atherosclerotic cardiovascular disease (ASCVD). ASCVD is the leading cause of morbidity and mortality in the United States. Regular physical activity has been shown to reduce the risk of ASCVD, but less than 50% of US adults achieve enough physical activity to obtain these benefits.

Eligibility Criteria
Inclusion Criteria
- Age 18 years or older
