简要总结
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).
详细描述
Background and aim: Sedentary behaviour has substantial impact on wellbeing and health, e.g. on the risk of cardiovascular disease and premature death. These associations seem to apply as well to people who carry out the recommended 30 minutes of physical activity per day. However, studies indicate that the harmful effects can be reduced through breaking prolonged periods of sitting by intervals of standing or walking.
In total 46 % of Danes are working in occupations which are primarily sedentary and the workplace is thus a relevant setting to intervene against sedentary behaviour.
The aim of the study is to test an intervention towards sitting time among office workers. The intervention will target both total sitting time, breaks from sitting and prolonged periods of sitting.
Design: Cluster-randomized control study led at four different workplaces in Denmark and Greenland. Each workplace should consist of four independent sections (clusters) of about 25 people. Those four sections are randomized to intervention or control. A cluster design is used because the intervention will target the workplace setting as a whole, thus individuals within the same office has to be randomized to the same arm of the intervention.
Participants: 400 adults with sedentary office-based work. Subjects should understand Danish and be without disabilities or diseases affecting their ability to stand or walk.
