Outcome Measures

Primary Outcomes (1)

  • Total time spent sitting at work

    Total time spent sitting at work will be objectively measured using a tri-axial accelerometer

    12 weeks

Secondary Outcomes (4)

  • Total time spent sitting at work in continuous bouts of at least 30 minutes.

    12 weeks

  • Number of sitting events at work

    12 weeks

  • Number of prolonged sitting events at work

    12 weeks

  • Time after prompt to stand

    12 weeks

Study Arms (2)

Prompt group

EXPERIMENTAL

Following feedback on their baseline sitting behaviour and an education session on the health benefits of breaking prolonged sitting, the prompt group will receive hourly prompts on their PC to stand. The prompts will be delivered via Microsoft Outlook and will run for a period of 10 weeks. The messages will be short in length, varied and centre around the key message of breaking prolonged sitting by standing

Behavioral: Hourly prompts to stand delivered by Microsoft Outlook

Control group

NO INTERVENTION

The control group will receive the same education session as the prompt group, as well as feedback on their baseline sitting behaviour. However, the will not receive prompts on their PC.
