Stand & Move at Work

Not Applicable

Completed

Brief Summary: A trial testing the efficacy of sit-stand workstations on decreasing sitting time and increasing light-intensity physical activity in samples of office worksites.

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.

Arm && Interventions

Group	Intervention	Description
Move	Move	A multi-level individual, social, environmental, and organizational intervention targeting increases in light-intensity physical activity in the workplace.
Stand & Move	Sit-Stand workstation	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.

Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
Clustered Metabolic Risk Score From Baseline to 12 Months	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.
