Brief 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Workplace sitting time to be reduced | 12 months | Workplace sitting time will be reduced by 60 minutes across an 8 hour work day and this time will be replaced by standing. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Total sitting time will be reduced | 12 months | 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 | 12 months | Energy expenditure will increase across an 8 hour workday and a 16 hour day. |
| Health behavior change of consuming a lower fat diet | 12 months | 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 | 6 months | Body weight, BMI, and fast mass will be reduced by 6 months. |
| Changes in musculoskeletal symptoms | 12 months | Increases in standing behavior will be correlated with changes in musculoskeletal symptoms. |
