Studies using technical measurements of physical behavior show wide interindividual variations. This study aimed to explore underlying factors related to sitting, standing and walking among office workers. Cross-sectional data for background characteristics, work-related variables, and device-based measures for sitting, standing and walking were collected among office workers in either a cell office or a flex office with activity-based work. Data were analyzed by Factor Analysis of Mixed Data (FAMD) and multiple robust linear regression. The FAMD resulted in the combination of underlying factors describing six character types. The (1) harmonic and healthy, (2) disabled with poor health, (3) manager that spend a lot of time in meetings and has very high workload, (4) engaged with high workload, (5) employee with creative and computer intense work, with high workload and, (6) employee with high BMI with creative and collaborative work. Regression analysis showed that the character type that was "engaged with high workload" sat more and stood less, while the character type with "high BMI and with creative and collaborative work" sat less. The results suggest that physical behavior among office workers is influenced by a complex combination of factors, which should be taken into account in the evaluation of future studies of larger cohorts.
使用身体行为的技术测量进行的研究表明个体间存在广泛的差异。本研究旨在探索与办公人员的坐姿、站姿和步行有关的潜在因素。在采用基于活动的工作方式的细胞办公室或灵活办公室中，收集了办公人员的背景特征、与工作相关的变量以及基于设备的坐姿、站姿和步行测量的横断面数据。通过混合数据因子分析（FAMD）和多元稳健线性回归对数据进行分析。FAMD 得出了描述六种特征类型的潜在因素的组合。这些特征类型包括：（1）和谐健康型，（2）身体残疾且健康状况不佳型，（3）经理型，他们经常开会且工作量很大，（4）投入型，工作量很大，（5）从事创造性和计算机密集型工作且工作量大的员工，（6）BMI 高且从事创造性和协作性工作的员工。回归分析表明，“投入且工作量大”的特征类型的人坐得更多，站得更少，而“BMI 高且从事创造性和协作性工作”的特征类型的人坐得更少。结果表明，办公人员的身体行为受到多种因素的复杂组合的影响，在评估更大队列的未来研究时应考虑这些因素。
