Standing Behavior After Installation of Height-Adjustable Desks

Not Applicable

Completed

• Conditions: Office Workers; Sitting Occupations

• Registration Number: NCT01787643
• Lead Sponsor: USDA Grand Forks Human Nutrition Research Center

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.

• Consents to study conditions

Exclusion Criteria

• Cannot stand for any type of health of orthopedic reasons

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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.
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.
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.
