Be Fit in Residency: a Randomized Controlled Trial of an Activity Device Among Medicine Residents

This study has been completed.
Sponsor:
Collaborator:
National Heart, Lung, and Blood Institute (NHLBI)
Information provided by (Responsible Party):
Anne N. Thorndike, MD, MPH, Massachusetts General Hospital
ClinicalTrials.gov Identifier:
NCT01287208
First received: January 28, 2011
Last updated: October 31, 2012
Last verified: October 2012
  Purpose

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.

Other Name: Fitbit
Placebo Comparator: Blinded
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
