This cross-sectional pilot study of 26 office workers used body-worn sensors to measure movement behavior during work and leisure. It found that the number of posture transitions during work was significantly higher in workers reporting musculoskeletal discomfort, and that transitions during leisure were negatively correlated with body mass index and heart rate.
This cross-sectional pilot study investigated associations between daily movement behavior, musculoskeletal discomfort (MSD), and cardiometabolic health in 26 sedentary office workers. Participants wore thigh-based inertial measuring units, heart rate monitors, and ambulatory blood pressure cuffs to quantify posture time, transitions, step counts, and cardiometabolic measures during work and leisure. Key results showed that participants with MSD had significantly more posture transitions during work hours. Moderate negative correlations were found between leisure-time transitions and both body mass index and heart rate. The study found no single behavior strongly correlated with health outcomes, but suggested that a combination of increased standing, walking, and posture transitions during both work and leisure was associated with positive health indicators. Limitations include the small, convenience sample from a university (potentially more active than typical sedentary workers), the cross-sectional design preventing causal inference, and the exclusion of physical activity intensity measures.
