Brief Summary:
Decreased physical activity is not only associated with multiple chronic medical conditions, including obesity, but also with depressed mood, and other negative emotions. As many employed adults spend a great deal of time at work where we are predominantly sedentary, strategies to increase physical activity at work are being pursued to help improve the physical and mental health of Americans. This 17 week randomized controlled trial will investigate changes of occupational physical activity in three groups: those provided with a FitBit® but not able to monitor their activity level, and those provided with activity goals and individual physical activity challenges, and those who do not use a FitBit®.

Condition or disease Intervention/treatment Phase
Physical Activity Device: Blinded Fitbit Device: Unblinded Fitbit Not Applicable

Detailed Description:
All subjects will be entered into a 4 week run-in phase where subjects will wear a blinded Fitbit during work hours. The baseline work activity is collected at this time. This phase is followed by a randomization to one of 3 groups: the blinded Fitbit group, the unblinded Fitbit group, and the group which will not wear any activity monitors. During these 12 weeks we will collect data on activity levels during work hours. Everyone will have a final contact at week 17 to close out the study.

Arm Intervention/treatment
Sham Comparator: Blinded Fitbit
Subjects will wear the physical activity monitor (fitbit) for 12 weeks but will be blinded to the monitor display.
Device: Blinded Fitbit
Subjects will wear a blinded Fitbit to monitor activity while in the workplace for 12 weeks.

Active Comparator: Unblinded Fitbit
Subjects will wear the physical activity monitor (fitbit) for 12 weeks. They will have access to the monitor display and will have consults with study physician to set goals for the duration of the study.
Device: Unblinded Fitbit
Subjects will be unblinded to the Fitbit display for 12 weeks with set activity goals.

No Intervention: No Fitbit
Subjects will not wear any activity monitor for 12 weeks.

Primary Outcome Measures :
  1. Change in Fitbit Step Count Per Day [ Time Frame: Baseline through Week 16 ]
    change in number of daily steps as measured by the fitbit monitor
