Occupational sitting time in white-collar workers represents a prominent contributor to overall daily sitting time, which is associated with various health risks. Workplace interventions intending to reduce sitting time during work typically focus on replacing sitting with standing. The aim was to investigate and compare actual and desired proportions of time spent sitting, standing, walking, and doing physically demanding tasks at work reported by desk-based workers. Cross-sectional data were collected from German desk-based workers (n = 614; 53.3% men; 40.9 ± 13.5 years). All were interviewed about their self-reported actual and desired level of sitting, standing, walking and physically demanding tasks at work.
Desk-based workers reported to sit 73.0%, stand 10.2%, walk 12.9% and do physically demanding tasks 3.9% of their working hours. However, the individuals desire to sit, stand, walk and do physically demand tasks significantly different [53.8% sit, 15.8% stand, 22.8% walk, physically demanding tasks (7.7%), p < 0.001]. The present data revealed greatest mismatch between the desk-based workers' actual and desired time for sitting and walking. Health promotion programs should offer not only options for more standing but also opportunities for more walking within the workplace setting to better match workers' desires.
白领的职业久坐时间是每日总久坐时间的一个重要组成部分，而总久坐时间与多种健康风险相关。旨在减少工作期间久坐时间的工作场所干预措施通常侧重于用站立代替久坐。目的是调查并比较伏案工作者报告的在工作中坐着、站立、行走以及从事体力要求较高任务的实际时间比例和期望时间比例。从德国伏案工作者（n = 614；53.3%为男性；40.9±13.5岁）中收集横断面数据。所有参与者都接受了关于他们自我报告的在工作中坐着、站立、行走以及从事体力要求较高任务的实际水平和期望水平的访谈。
伏案工作者报告称，他们在工作时间内73.0%的时间坐着，10.2%的时间站立，12.9%的时间行走，3.9%的时间从事体力要求较高的任务。然而，个体对于坐着、站立、行走以及从事体力要求较高任务的期望存在显著差异[53.8%坐着，15.8%站立，22.8%行走，从事体力要求较高任务（7.7%），p < 0.001]。目前的数据显示，伏案工作者坐着和行走的实际时间与期望时间之间的差距最大。健康促进项目不仅应提供更多站立的选择，还应在工作场所环境中提供更多行走的机会，以更好地符合员工的期望。
