MapTrek for Sedentary Workers

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to determine if participants randomized to our mHealth MapTrek game increases daily physical activity (average steps/day, active minutes/day) compared to a control group among sedentary office workers over 10 weeks. The investigators hypothesize the MapTrek intervention group will significantly increase their daily steps and active minutes compared to the control group over 10 weeks.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Fitbit-only Group<br>Participants received a Fitbit Zip activity monitor to wear daily for 10 weeks. | Behavioral: Fitbit only<br>* Users receive a Fitbit Zip to wear daily.<br>|
| Experimental: Fitbit + MapTrek Group<br>Participants received a Fitbit Zip activity monitor to wear daily for 10 weeks. Participants also received access to an mHealth game called MapTrek for 10 weeks. MapTrek places users in weekly walking races and sends automated text messages to participants on a daily basis. Messages include a link to the online game as well as motivational messages designed to increase physical activity. | Behavioral: Fitbit + Maptrek<br>* Users receive a Fitbit Zip to wear daily.
