Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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:

1. 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).
2. To determine if an unblinded team competition using the activity device directly following the randomized phase increases residents' activity level compared to baseline.
3. To determine if activity level is associated with change in weight during the residency year.
4. To determine if the average hours of sleep per week is associated with changes in weight and with activity level.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type ACTIVE_COMPARATOR

Activity monitor

Intervention Type DEVICE

The activity monitor is an accelerometer that records steps, distance, calories, and sleep

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.

Group Type PLACEBO_COMPARATOR

Activity device

Intervention Type DEVICE

Accelerometer that has all the steps, distance, calories, and sleep data blinded to the study subject
