Stand & Move at Work

Arizona State University630 enrolled

Overview

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

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.

Outcomes

Primary Outcomes

Mean Change in Light-intensity Physical Activity at Work From Baseline to 12 Months

Measured via 7d of activPAL accelerometry (value at 12 months minus value at baseline)

Time frame: 1 year

Mean Change in Sitting Time at Work From Baseline to 12 Months

Measured via 7d of activPAL accelerometry (value at 12 months minus value at baseline)

Time frame: 1 year

Secondary Outcomes

Clustered Metabolic Risk Score From Baseline to 12 Months

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.

Time frame: 1 year
