Arms Assigned Interventions
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.
Behavioral: education talk and leaflet
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 stating with the same message is also provided.
Experimental: prompt + education
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. Prompting software (MyRestBreak 1.0 copyright Vikram Sharma) will be installed on the work computer. A prompt with the message "stand up, take a break" is placed on the screen of the work computer for 1 minutes every 30 minutes, from the time the computer is switched on in the morning. The prompt is contained in a window 11x9 cm in the centre of the screen. The prompt cannot be removed or minimised, but work can continue in any windows visible around the prompt. The prompt is on the computer for 5 days.

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.
