简要总结
The purpose of this study was to determine whether the installation of sit-stand work stations could lead to decreased sedentary time and increased physical activity during the workday among sedentary office workers.

研究组 & 干预措施
Sit-Stand Desk
Cross-over trial: so one group got the intervention in period 1 and didn't get the intervention in period 2 (serving as control for self in period 2) and the other group got the intervention in period 2 and didn't get the intervention in period 1 (serving as control for self in period 1).
干预措施: Sit-Stand Desk (Other)
Control
Used normal work desk which only allows working sitting down
结局指标
主要结局
non-exercise activity
时间窗: Measured constantly during the entire control period and measured constantly during the entire intervention period and the two periods were compared to determine change in non-exercise activity
Non-exercise activity was meausred by triple axis accelerometers during all waking hours in the control period (1 month) and in the intervention period (1 month). The two periods were then compared for each subject. Sitting time was also measured subjectively using a validated questionnaire: occupational sitting and physical activity questinnarie (OSPAQ) Hypothesis: Amount of time spent standing, walking, and other components of non-exercise activity will be higher during the standing intervention period relative to the control period (usual sitting).
次要结局
- Individual Interviews to Qualitatively ascertain experience with Sit-Stand Desks(End of control period and end of intervention period)
- Productivity Survey(Once a week for 4 weeks of control period and 4 weeks of intervention period and the two periods were compared)
- Body composition and fitness(Beginning of control period, end of control period (4 weeks later), beginning of intervention period, and end of intervention period)
- 24 hr Diet recall(Once a week for 4 weeks of control period and 4 weeks of intervention period and the two periods were compared)
- Stress(Once every two weeks for 4 weeks of control period and 4 weeks of intervention period and the two periods were compared)
- Ecological Momentary Assesment Fatigue, appetite, energy levels Sitting/standing, Fatigue, appetite, energy levels Self-administered web-based ecological momentary assessments(Twice per day during workdays (5 days a week) for 4 weeks of control period and 4 weeks of intervention period and the two periods were compared)
- 24 hour Physical Activity Recall(Once a week for 4 weeks of control period and 4 weeks of intervention period and the two periods were compared)
- Focus Group Sessions to Qualitatively ascertain experience with Sit-Stand Desks(End of Study)
