Study Description
Brief Summary:
The purpose of this study is to determine whether an on-screen prompt put on the work computer every 30 minutes is effective in getting office workers to reduce prolonged periods of sitting at work.

Condition or disease Intervention/treatment Phase
Adult Office Workers Device: MyRestBreak 1.0 Behavioral: education talk and leaflet Phase 1

Detailed Description:
Prolonged bouts of uninterrupted time spent sitting is associated with indicators of poor health, independent of how physically active a person is. Many occupations are now sedentary, and are characterised by long periods spent sitting at a desk. Brief education on the benefits of standing regularly and breaking up prolonged sitting will be provided to participants, working at a Scottish University. One intervention group will additionally have software installed on their work computer which placed a prompt window in the centre of their screen for 1 minute every 30 minutes. The prompt will remind participants to stand-up and take a break, and the window cannot be removed or minimised.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: education only
A short educational talk, read from a script, regarding the health risks of prolonged sitting, stating that standing every 30 minutes could be beneficial. A short information leaflet with the same message is also provided.
