Detailed Description

With traditional approaches to increasing MVPA (moderate to vigorous physical activity) in the workplace being unsustainable due to the requirement of deliberate and dedicated time away from work, this group-randomized trial will test the efficacy of sit-stand workstations on decreasing sitting time and increasing light-intensity physical activity (LPA) in a highly generalizable sample of office worksites using a multi-level intervention with high potential for dissemination.

Interventions

  • Device: Sit-Stand workstation
    • Installation of a sit-stand desk at work
  • Behavioral: Move
    • A multi-level individual, social, environmental, and organizational intervention targeting increases in light-intensity physical activity in the workplace

Arms, Groups and Cohorts

  • Active Comparator: Move
    • A multi-level individual, social, environmental, and organizational intervention targeting increases in light-intensity physical activity in the workplace.
  • Experimental: Stand & Move
    • Move intervention (A multi-level individual, social, environmental, and organizational intervention targeting increases in light-intensity physical activity in the workplace) plus the installation of a sit-stand workstation.

Clinical Trial Outcome Measures

Primary Measures

  • Mean Change in Light-intensity Physical Activity at Work From Baseline to 12 Months
    • Time Frame: 1 year
    • Measured via 7d of activPAL accelerometry (value at 12 months minus value at baseline)
  • Mean Change in Sitting Time at Work From Baseline to 12 Months
    • Time Frame: 1 year
    • Measured via 7d of activPAL accelerometry (value at 12 months minus value at baseline)

Secondary Measures

  • Clustered Metabolic Risk Score From Baseline to 12 Months
    • Time Frame: 1 year
    • Clustered metabolic risk score (fasting glucose, insulin, triglycerides, HDL-cholesterol, blood pressure); value at 12 months minus value at baseline; higher scores indicate better outcome. The Z-score for each component (fasting glucose, insulin, triglycerides, HDL-cholesterol, blood pressure) based on the baseline mean and standard deviation of the entire group was computed and summed for each participant (HDL z-score was subtracted rather than added). The sum of these z-scores represents the metabolic risk score.
