WorkWell: Work-based Activity and Metabolic Health
WorkWell: A Pre-clinical Pilot Study of Increased Standing and Light-intensity Physical Activity in Prediabetic Sedentary Office Workers
Study Overview
Status
Conditions
Detailed Description
This pilot study is being conducted to determine whether a range of pre-clinical cardiometabolic biomarkers (measured via gut microbiome, blood draw) can be improved via regular intervals of standing and light-intensity physical activity (i.e., leisurely walking) in real-world office environments. This trial is meant to generate pilot data which will lead to additional clinical trials.
Primary Hypothesis: Increasing both standing and light-intensity physical activity will improve biomarkers of metabolic function, as measured by blood metabolites and differential abundance of gut microbiome composition, compared to a control condition of normal workplace behavior.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Move, Stand
Usual behavior condition, followed by the standing condition, followed by the LPA condition.
|
Participants will be asked to stand an additional 6 minutes per hour above their median standing time from the observed time in the usual behavior condition.
Participants will be asked to perform 6 additional minutes per hour above their median LPA time from the observed time in the usual behavior condition.
Participants will be asked to perform their normal work activities in their normal work environment for one week.
There will be no modifications to their work environment or instructions given of what activities to partake in.
This period will be used to understand their normal standing and LPA behaviors to determine the personalized changes to their standing and LPA behaviors in the other conditions.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in 2-hour postprandial area-under-the-curve blood glucose at 2 weeks
Time Frame: 2 weeks
|
Participants will be asked to wear the Abbott Freestyle Libre continuous glucose monitor during the usual behavior condition (week 1) and both experimental conditions (weeks 2-3 and weeks 5-6).
Research staff will insert the CGM sensor at the screening and study visits.
The training for this insertion will be conducted by a registered research nurse.
The CGM sensors have been designed and tested to be worn continuously for up to 14 days.
Sensors will be placed and removed by trained research staff at appropriate time-points throughout the study.
Postprandial period will follow a standardize lunch meal.
Area-under-the-curve calculations will be based on 2 hours following delivery of this lunch meal.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in baseline workplace standing time at 2 weeks
Time Frame: 2 weeks
|
Participants will be asked to wear an activPAL accelerometer throughout the entire intervention period.
Data from the devices will be downloaded at each study visit.
The activPAL device is worn on the right thigh and is equipped with low energy Bluetooth and will communicate wirelessly with the provided smartphone application to provide feedback to the participant and compliance with the protocol.
Workplace time will be assessed by a self-report log and activPAL time will be extracted based on these reports.

Participants will be asked to wear an activPAL accelerometer throughout the entire intervention period.
Data from the devices will be downloaded at each study visit.
The activPAL device is worn on the right thigh and is equipped with low energy Bluetooth and will communicate wirelessly with the provided smartphone application to provide feedback to the participant and compliance with the protocol.
Workplace time will be assessed by a self-report log and activPAL time will be extracted based on these reports.

Measure Description |
Time Frame |
---|---|---|
Treatment acceptability/satisfaction
Time Frame: 2 weeks
|
Intervention acceptability questionnaire at the end of each condition will elicit each participant's perceived acceptability of the intervention.
|

|
Change in fasting blood glucose at 2 weeks
Time Frame: 2 weeks
|
After verifying fasting for 10-12 hours, a blood sample (about 15 ml, approximately 1 tablespoon) will be collected via venipuncture to measure markers of glucose.
After withdrawal, blood will be centrifuged at 1,100 x g at 4°C for 20 minutes, and serum, plasma and erythrocytes will be aliquoted and stored at -80 degrees Celsius for subsequent analysis upon sample collection completion.
Blood will be drawn by Arizona Biomedical Collaborative Laboratory clinical staff.
|
2 weeks
|
Change in femoral artery reactivity at 2 weeks
Time Frame: 2 weeks
|
Femoral Artery Flow Mediated Dilation (FAFMD) Endothelium-dependent dilation of the femoral artery will be measured using B-mode ultrasound (Terason uSmart 3300+™, Burlington MA) using guidelines set forth by the Brachial Artery Reactivity Task Force.
|
2 weeks
|
Change in central aortic diastolic and systolic blood pressure at 2 weeks
Time Frame: 2 weeks
|
All participants will lay down in a dimly lit room and have resting blood pressure measured using an automated blood pressure machine.
Thereafter, an appropriately sized blood pressure cuff will be placed on the left arm and central and peripheral blood pressures will be assessed using the non-invasive SphygmoCor system.
