Sedentary behavior, which is highly prevalent among office workers, is associated with multiple health disorders, including those of the musculoskeletal and cardiometabolic systems. Although prior studies looked at postures or physical activity during work or leisure time, few analyzed both posture and movement throughout the entire day.
This cross-sectional pilot study examined the movement behavior of sedentary office workers during both work and leisure time to explore its association with musculoskeletal discomfort (MSD) and cardiometabolic health indicators.
Twenty-six participants completed a survey and wore a thigh-based inertial measuring unit (IMU) to quantify the time spent in different postures, the number of transitions between postures, and the step count during work and leisure time. A heart rate monitor and ambulatory blood pressure cuff were worn to quantify cardiometabolic measures. The associations between movement behavior, MSD, and cardiometabolic health indicators were evaluated.
The number of transitions differed significantly between those with and without MSD. Correlations were found between MSD, time spent sitting, and posture transitions. Posture transitions had negative correlations with body mass index and heart rate.
Although no single behavior was highly correlated with health outcomes, these correlations suggest that a combination of increasing standing time, walking time, and the number of transitions between postures during both work and leisure time was associated with positive musculoskeletal and cardiometabolic health indicators among sedentary office workers and should be considered in future research.
久坐行为在上班族中非常普遍，与多种健康障碍有关，包括肌肉骨骼和心血管代谢系统的障碍。尽管先前的研究关注工作或休闲时间的姿势或体力活动，但很少有研究分析一整天的姿势和运动。
本横断面初步研究调查了久坐上班族在工作和休闲时间的运动行为，以探讨其与肌肉骨骼不适（MSD）和心血管代谢健康指标的关系。
26 名参与者完成了一项调查，并佩戴了大腿基础惯性测量单元（IMU），以量化在不同姿势下花费的时间、姿势之间的转换次数以及工作和休闲时间的步数。佩戴心率监测器和动态血压袖带以量化心血管代谢测量值。评估了运动行为、MSD 和心血管代谢健康指标之间的关联。
有和没有 MSD 的人之间的转换次数有显著差异。MSD、坐姿时间和姿势转换之间存在相关性。姿势转换与体重指数和心率呈负相关。
虽然没有单一行为与健康结果高度相关，但这些相关性表明，在工作和休闲时间增加站立时间、步行时间和姿势转换次数与久坐上班族的肌肉骨骼和心血管代谢健康指标呈正相关，应在未来的研究中考虑。
