About this study
Official title: Adoption of Standing Behavior After Installation of Height-Adjustable Desks
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 12 months
Secondary outcomes (5)
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.
Measured: 12 months
Energy expenditure will increase
Energy expenditure will increase across an 8 hour workday and a 16 hour day.
Measured: 12 months
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.
Measured: 12 months
Body weight, BMI, and fat mass reduction
Body weight, BMI, and fast mass will be reduced by 6 months.
Measured: 6 months
Changes in musculoskeletal symptoms
Increases in standing behavior will be correlated with changes in musculoskeletal symptoms.
Measured: 12 months
