Study Description

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.

Condition or disease	Intervention/treatment	Phase
Obesity; Hypertension; Diabetes	Device: Sit-Stand workstation; Behavioral: Move	Not Applicable

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.

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 630 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Masking: None (Open Label)
• Primary Purpose: Prevention
• Official Title: Stand & Move at Work: A Group Randomized Trial
• Actual Study Start Date: January 15, 2016
• Actual Primary Completion Date: December 15, 2017
• Actual Study Completion Date: December 15, 2018

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Move; A multi-level individual, social, environmental, and organizational intervention targeting increases in light-intensity physical activity in the workplace.	Behavioral: 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.	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

Outcome Measures

Primary Outcome Measures :

1. 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)
2. 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 Outcome Measures :

1. 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.

Other Outcome Measures:

1. Sleep Substudy [ Time Frame: 1 year ]
   24h wrist accelerometry in individuals with minor-moderate sleep complaints
2. Ambulatory Blood Pressure [ Time Frame: 3 months ]
   Dynamic changes in ambulatory blood pressure in prehypertensives
3. Ecological Momentary Assessment of Mood [ Time Frame: 1 year ]
   Periodic monitoring of mood, energy, fatigue in smartphone users
4. Dynamic Glucose Control [ Time Frame: 3 months ]
   Continuous glucose monitoring in prediabetics
