NCT01996176

Brief Summary

The purpose of the study is to test an intervention aiming to reduce sitting time during work hours among office workers. Expectations according to outcome measures: Sitting time reduced by 1 hour pr. day (primary). Number of prolonged periods reduced by 1 pr. day (primary). Number of breaks increased by 3 pr. day (primary). 20 % of participants report a reduction of musculoskeletal pain (secondary). A reduction in waist circumference of 1 cm (secondary). A reduction of 0.5 % in bodyfat (secondary).

Interventions

Intervention groupBEHAVIORAL

The intervention consists of four components, which as described below: 1. Information about sedentary behaviour and health: Delivered at the kick-off workshop, in a leaflet and the project website. 2. Local adaptation: Participants adapt the intervention to their personal and local environment setting individual and common goals. Local ambassadors are chosen and support from the management is emphasised. 3. Structural changes: Facilities for standing meetings, both formal and informal. Routes for walking meetings should be defined. 4. Individual support: At the kick-off workshop participants set individual goals. The individual can choose to receive e-mails and text messages (SMS)from the project. The individual receives a post-it block and a postcard to remind them of the project.

Intervention group
Control groupBEHAVIORAL

The control group receives the intervention after the last follow-up, the exact time will be settled together with each workplace in the control group.
