目的：这项研究的目的是确定在久坐的办公室工作人员中，安装坐立两用办公桌（SSD）是否会导致工作时间减少。方法：2012年1月至4月在明尼阿波利斯的一家企业进行了一项随机交叉试验。28名（9名男性，26名全职）久坐的办公室工作人员参加了为期4周的干预期，其中包括使用SSD在工作日逐渐取代50%的坐姿时间。体力活动是主要结局。情绪，能量水平，疲劳，食欲，饮食摄入量和生产力作为次要结果进行了探讨。结果：干预减少了21%（95%CI 18%-25%）的工作坐着的时间和4.8分钟/工作小时（95%CI 4.1-5.4分钟/工作小时）的久坐时间。对于40小时的工作周，这意味着用站立和久坐时间减少3.2小时来取代8小时的坐姿时间。非工作时间的活动水平没有变化。干预还增加了整体的幸福感，能量，减少疲劳，对生产力没有影响，并减少食欲和饮食摄入。工作站受到与会者的欢迎。结论：SSD干预成功地提高了工作时间的活动水平，而不改变非工作时间的活动水平。
Objective: This study was conducted to determine whether installation of sit-stand desks (SSDs) could lead to decreased sitting time during the workday among sedentary office workers. Methods: A randomized cross-over trial was conducted from January to April, 2012 at a business in Minneapolis. 28 (nine men, 26 full-time) sedentary office workers took part in a 4 week intervention period which included the use of SSDs to gradually replace 50% of sitting time with standing during the workday. Physical activity was the primary outcome. Mood, energy level, fatigue, appetite, dietary intake, and productivity were explored as secondary outcomes. Results: The intervention reduced sitting time at work by 21% (95% CI 18%–25%) and sedentary time by 4.8 min/work-hr (95% CI 4.1–5.4 min/work-hr). For a 40 h work-week, this translates into replacement of 8 h of sitting time with standing and sedentary time being reduced by 3.2 h. Activity level during non-work hours did not change. The intervention also increased overall sense of well-being, energy, decreased fatigue, had no impact on productivity, and reduced appetite and dietary intake. The workstations were popular with the participants. Conclusion: The SSD intervention was successful in increasing work-time activity level, without changing activity level during non-work hours.
