Clinical Trial Summary

The purpose of this research study is to determine whether height-adjustable desks change sitting and standing time at work and away from work, engery expenditure, dietary intake, and body composition. Intermittent peroids of standing made possible by height-adjustable desks may help to impart long-term health benefits.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Workplace sitting time to be reduced	Workplace sitting time will be reduced by 60 minutes across an 8 hour work day and this time will be replaced by standing.	12 months
Secondary	Total sitting time will be reduced	Total sitting time will be reduced by 30 minutes across a 16 hour day. Decreased sitting during the weekday will not be fully compensated for by increased sitting during nonwork hours.	12 months
Secondary	Energy expenditure will increase	Energy expenditure will increase across an 8 hour workday and a 16 hour day.	12 months
Secondary	Health behavior change of consuming a lower fat diet	The non-targeted health behavior of consuming a lower fat diet will co-occur with standing behavior. Increases in standing behavior will be inversely correlated with changes in total dietary fat intake.	12 months
Secondary	Body weight, BMI, and fat mass reduction	Body weight, BMI, and fast mass will be reduced by 6 months.	6 months
Secondary	Changes in musculoskeletal symptoms	Increases in standing behavior will be correlated with changes in musculoskeletal symptoms.	12 months
