To investigate whether or not use of sit-stand desks and awareness of the importance of postural variation and breaks are associated with the pattern of sedentary behavior in office workers.
The data came from a cross-sectional observation study of Swedish call centre workers. Inclinometers recorded 'seated' or 'standing/walking' episodes of 131 operators over a full work shift. Differences in sedentary behavior based on desk type and awareness of the importance of posture variation and breaks were assessed by non-parametric analyses.
90 (68.7%) operators worked at a sit-stand desk. Working at a sit-stand desk, as opposed to a sit desk, was associated with less time seated (78.5 vs 83.8%, p = 0.010), and less time taken to accumulate 5 min of standing/walking (36.2 vs 46.3 min, p = 0.022), but no significant difference to sitting episode length or the number of switches between sitting and standing/walking per hour. Ergonomics awareness was not associated with any sedentary pattern variable among those using a sit-stand desk.
Use of sit-stand desks was associated with better sedentary behavior in call centre workers, however ergonomics awareness did not enhance the effect.
研究坐站式办公桌的使用情况以及对姿势变化和休息重要性的认识是否与办公室工作人员久坐行为模式有关。
数据来自对瑞典呼叫中心工作人员的横断面观察研究。测倾仪记录了 131 名操作员在整个工作班次中的“坐姿”或“站立/行走”时段。通过非参数分析评估基于办公桌类型和对姿势变化和休息重要性的认识的差异。
90（68.7%）名操作员在坐站式办公桌前工作。与坐式办公桌相比，使用坐站式办公桌与更少的坐姿时间（78.5%对 83.8%，p=0.010）和更少的时间积累 5 分钟站立/行走时间（36.2 分钟对 46.3 分钟，p=0.022）相关，但每小时坐姿时间、坐姿和站立/行走之间的切换次数没有显著差异。在使用坐站式办公桌的人员中，人体工程学意识与任何久坐行为模式变量均无关。
在呼叫中心工作人员中，使用坐站式办公桌与更好的久坐行为有关，但人体工程学意识并没有增强这种效果。
