Brief Summary

This study will test whether a range of pre-clinical cardiometabolic biomarkers can be improved via regular intervals of standing and light-intensity physical activity in real-world office environments.

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.

Primary Outcome Measures
NameTimeMethod
Change in 2-hour postprandial area-under-the-curve blood glucose at 2 weeks2 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
NameTimeMethod
Change in baseline workplace standing time at 2 weeks2 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.
