Take a Stand!-a multi-component intervention aimed at reducing sitting time among office workers-a cluster randomized...

Area of Science:

• Occupational Health
• Behavioral Science
• Public Health

Background:

• Prolonged sitting is linked to negative health outcomes.
• Workplace interventions can mitigate risks associated with sedentary behavior.
• Reducing sitting time is crucial for office worker well-being.

Purpose of the Study:

• To evaluate a multicomponent workplace intervention's effectiveness.
• To assess reductions in sitting time and prolonged sitting periods.
• To measure increases in sit-to-stand transitions and changes in body composition.

Main Methods:

• Cluster randomized trial involving 317 office workers across four workplaces.
• Intervention included local ambassadors, management support, environmental changes, lectures, and workshops.
• Sitting time measured via ActiGraph, with follow-up at 1 and 3 months.

Main Results:

• Significant reductions in sitting time (71 min/workday at 1 month) and prolonged sitting periods.
• Increased sit-to-stand transitions (+14%/sitting hour at 1 month).
• Reduced body fat percentage by 0.61 percentage points after 3 months.

Conclusions:

• Multicomponent workplace interventions effectively reduce sitting time.
• These interventions improve health markers like body fat percentage.
• Workplace strategies can successfully increase physical activity transitions.
