Purpose

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.

Primary Outcome Measures:

Workplace sitting time to be reduced [ Time Frame: 12 months ] [ Designated as safety issue: No ]
Workplace sitting time will be reduced by 60 minutes across an 8 hour work day and this time will be replaced by standing.

Secondary Outcome Measures:

Total sitting time will be reduced [ Time Frame: 12 months ] [ Designated as safety issue: No ]
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.
Energy expenditure will increase [ Time Frame: 12 months ] [ Designated as safety issue: No ]
Energy expenditure will increase across an 8 hour workday and a 16 hour day.
Health behavior change of consuming a lower fat diet [ Time Frame: 12 months ] [ Designated as safety issue: No ]
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.
Body weight, BMI, and fat mass reduction [ Time Frame: 6 months ] [ Designated as safety issue: No ]
Body weight, BMI, and fast mass will be reduced by 6 months.
Changes in musculoskeletal symptoms [ Time Frame: 12 months ] [ Designated as safety issue: No ]
Increases in standing behavior will be correlated with changes in musculoskeletal symptoms.
