确定客观测量的工作场所久坐行为的社会生态相关因素。来自24个工作地点的参与者--来自学术、工业和政府部门--佩戴了7天的Active PAL-微型加速度计(2016年1月至11月)。工作时间使用每日日志进行分段。久坐的行为结果包括坐着、站着、轻强度体力活动(LPA，步频100步/分钟)和长时间静坐(30分钟)。结果被标准化为每天工作8小时。完成了两项电子调查，以得出个人(工作类型和工作参与度)、文化(午餐远离办公桌、午餐步行和面对面互动)、身体(个人打印机和办公室类型)和组织(部门)因素。混合模型分析和工作地点水平的聚类被用来检验多水平的关联。二次分析考察了作为这些关联的主持人的工作类型和部门。所有模特都根据年龄、种族/民族和性别进行了调整。参与者(女性=478人；女性占72%；年龄：45.0±11.3岁；非西班牙裔白人占77.8%)在报告工作日的90.2±115.5%的时间内佩戴激活型PAL-MICO。午餐步行与LPA呈正相关(5.0±0.5分钟/8小时，P<0.001)。有规律的面对面互动与久坐时间呈负相关(−为11.3%±44.8%分钟/8h，P<0.05)。与在公共办公室的人相比，私人办公室里的人坐得更多(20.1%±9.1%分钟/8小时，P&0.001)，站立更少(−21.5±8.8%分钟/8小时，P；0.05)，坐得更长(40.9%±11.2%分钟/8小时，P<；0.001)。这些联系还按工作类型和部门作了进一步修改。特定于工作的个人、文化、身体和组织因素与工作场所的久坐行为有关。关联因工作类型和行业而异，在设计工作场所干预措施以减少久坐行为时应考虑到这一点。临床试验编号：NCT02566317；2015年9月22日注册。
To identify social ecological correlates of objectively measured workplace sedentary behavior. Participants from 24 worksites - across academic, industrial, and government sectors - wore an activPAL-micro accelerometer for 7-days (Jan-Nov 2016). Work time was segmented using daily logs. Sedentary behavior outcomes included time spent sitting, standing, in light intensity physical activity (LPA, stepping cadence <100 steps/min), and in prolonged sitting bouts (>30 min). Outcomes were standardized to an 8 h work day. Two electronic surveys were completed to derive individual (job type and work engagement), cultural (lunch away from the desk, walking at lunch and face-to-face interaction), physical (personal printer and office type) and organizational (sector) factors. Mixed-model analyses with worksite-level clustering were performed to examine multi-level associations. Secondary analyses examined job type and sector as moderators of these associations. All models were adjusted for age, race/ethnicity and gender. Participants (N = 478; 72% female; age: 45.0 ± 11.3 years; 77.8% non-Hispanic white) wore the activPAL-micro for 90.2 ± 15.5% of the reported workday. Walking at lunch was positively associated with LPA (5.0 ± 0.5 min/8 h, P < 0.001). Regular face-to-face interaction was negatively associated with prolonged sitting (−11.3 ± 4.8 min/8 h, P < 0.05). Individuals in private offices sat more (20.1 ± 9.1 min/8 h, P < 0.05), stood less (−21.5 ± 8.8 min/8 h, P < 0.05), and engaged in more prolonged sitting (40.9 ± 11.2 min/8 h, P < 0.001) than those in public office space. These associations were further modified by job type and sector. Work-specific individual, cultural, physical and organizational factors are associated with workplace sedentary behavior. Associations vary by job type and sector and should be considered in the design of workplace interventions to reduce sedentary behavior. Clinical trial No. NCT02566317; Registered Sept 22nd 2015.
