有研究表明，办公室环境是影响办公室工作人员体力活动（PA）和久坐行为（SB）的重要因素。然而，办公室环境变化（办公室翻修）的影响尚不清楚。本研究旨在探讨办公室装修后办公室员工的PA、SB及空间利用的变化。这项研究是在日本东京一家公司的三个办公室进行的自然实验。参与者是来自翻新组一个办公室的13名工人（平均年龄：37.9 ± 10.8岁，女性百分比：23.1%）和来自对照组两个办公室的29名工人（平均年龄：42.3 ± 11.2岁，女性百分比：31.0%）。在翻新工程中，我们引入了活动为本的工作模式，并安装了可调节高度的办公桌。ABW办公室旨在提供各种共享工作站，使员工能够根据自己的任务或心情选择工作站。使用加速度计测量和使用人工智能（AI）技术的视频图像对象检测方法来评估翻新前后的行为和空间利用率。翻新后两周，SB的显著改善（翻新前至翻新后的改善：346.8 +/- 28.6至321.2 +/- 17.8分钟/工作小时）和PA（总PA：173.2 +/- 28.6至198.8 +/- 17.8 min/工作小时;光强度PA：130.4 +/- 27.1至150.7 +/- 31.0 min/工作小时）。此外，物体探测分析的结果显示，办公室的中央通道和靠近入口或窗户的共用民政事务总署工作站比其他空间使用得更频繁。本研究显示，办公室装修可即时改善办公室的SB与PA。此外，已使用的空间和民政事务总署的工作站可以发挥重要作用，以提高员工的活动在一个ABW办公室。
It has been reported that office environment is an important determinant of physical activity (PA) and sedentary behavior (SB) in office workers. However, the effect of changes in office environment (office renovation) is unclear. The purpose of this study was to examine PA, SB, and space utilization changes among office workers in response to office renovation. This study was a natural experiment at three offices of a single company in Tokyo, Japan. The participants were, 13 workers from one office in the renovation group (mean age: 37.9 +/- 10.8 years, percentage of females: 23.1%) and 29 from two offices in the control group (mean age: 42.3 +/- 11.2 years, percentage of females: 31.0%). In the renovation, introduction of activity-based working (ABW) and installation of height-adjustable desks (HAD) were adopted. The ABW office was designed to provide various shared workstations, enabling the workers to choose workstations depending on their task or mood. Accelerometer measurement and object detection method using artificial intelligence (AI) technology for video images were used to assess behavior and space utilization before and after the renovation. Two weeks after the renovation, significant improvements in SB (pre- to post-renovation improvements: 346.8 +/- 28.6 to 321.2 +/- 17.8 min/working-hours) and PA (total PA: 173.2 +/- 28.6 to 198.8 +/- 17.8 min/working-hours; and light-intensity PA: 130.4 +/- 27.1 to 150.7 +/- 31.0 min/working-hours) were observed. In addition, the results of the object detection analysis showed that the central aisle of the office and shared HAD workstations near the entrance or window were utilized more frequently than the other spaces. This study suggested that office renovation could improve SB and PA immediately after the renovation. Moreover, utilized spaces and HAD workstations could play an important role to enhance employees' activity in an ABW office.
