The purpose of this study was to explore the relationship between ecological factors and occupational sedentary behavior (SB).
Cross-sectional online survey.
Participants were employees recruited from a large, public university in the Southeastern United States from August to November 2016.
The final sample included 527 (56% response rate) employees.
Data were collected through an 87-item survey using previously validated scales that assessed occupational SB, perceived behavioral control, barrier self-efficacy, self-regulation strategies, organizational social norms, office environment, and worksite climate.
One-way analysis of variance analyses were used to determine differences in occupational SB by demographic factors. A multivariate regression model was used to determine significant ecological determinants of occupational SB.
Mean SB was 342.45 (standard deviation = 133.25) minutes. Significant differences in SB were found by gender, education, and employment classification. Barrier self-efficacy and workplace connectivity, which evaluates the spatial layout of the office setting that may impact mobility within the workplace, were significant predictors of SB in the multivariate model.
Results from this study provide new information regarding the potential impact of workplace barriers and connectivity on occupational SB. The findings from this study support the inclusion of intervention modalities to minimize workplace barriers and increase workplace connectivity to increase workplace mobility and decrease SB.
本研究旨在探讨生态因素与职业久坐行为（SB）之间的关系。
横断面在线调查。
参与者为2016年8月至11月从美国东南部一所大型公立大学招募的员工。
最终样本包括527名员工（回复率为56%）。
通过一项包含87个条目的调查收集数据，该调查使用了先前验证过的量表，评估职业SB、感知行为控制、障碍自我效能、自我调节策略、组织社会规范、办公环境和工作场所气候。
采用单因素方差分析来确定职业SB在人口统计学因素方面的差异。使用多元回归模型来确定职业SB的重要生态决定因素。
平均SB为342.45分钟（标准差 = 133.25）。在性别、教育程度和就业分类方面发现了SB的显著差异。在多元模型中，障碍自我效能和工作场所连通性（评估可能影响工作场所内移动性的办公环境空间布局）是SB的显著预测因素。
本研究结果提供了关于工作场所障碍和连通性对职业SB潜在影响的新信息。本研究结果支持纳入干预方式，以尽量减少工作场所障碍并增加工作场所连通性，从而提高工作场所的移动性并减少SB。
