The main objective of this study is to test an intervention to increase the physical activity of medical residents, an employee population with little time for exercise. Specifically, the aims of this study are:
- To determine if providing medical residents with an activity device that measures steps, distance, and calories burned and tracks this information over time on a website increases residents' physical activity levels as measured by number of steps per day compared to a control group using a blinded activity device (no feedback).
- To determine if an unblinded team competition using the activity device directly following the randomized phase increases residents' activity level compared to baseline.
- To determine if activity level is associated with change in weight during the residency year.
- To determine if the average hours of sleep per week is associated with changes in weight and with activity level.

Active Comparator: Unblinded activity monitor
Subjects wear the activity device and can see the data on the device and on a website where the data is uploaded.
Device: Activity monitor
The activity monitor is an accelerometer that records steps, distance, calories, and sleep
Other Name: Fitbit
Placebo Comparator: Blinded activity monitor
Subjects wear a blinded activity device and cannot see the activity on the device and cannot log on to the website where the data gets uploaded.
Device: Activity device
Accelerometer that has all the steps, distance, calories, and sleep data blinded to the study subject
Other Name: Fitbit
- Steps Per Day [ Time Frame: 12 weeks ]Steps will be recorded on the activity device
- Distance Per Day [ Time Frame: 12 weeks ]Distance in miles recorded on activity device.
- Calories Burned Per Day [ Time Frame: 12 weeks ]Total calories burned per day recorded on activity device. This secondary outcome was not measured in the trial.
- Weight [ Time Frame: 6 months ]
- Hours of Sleep Per Night [ Time Frame: 12 weeks ]
Number of hours slept per night as recorded on activity device.
This secondary outcome was not measured in the trial.
