The Effect of an e-Health Intervention Designed to Reduce Prolonged Occupational Sitting on Mean Arterial Pressure

Abstract

<b>Objective:</b> To evaluate the effect of a workplace health intervention de-signed to reduce prolonged occupational sitting on the mean arterial pressure (MAP) of desk-based employees. <b>Methods:</b> This randomized controlled trial involved an experimental group who received an e-health intervention and a control group who did not. The 13-week intervention passively prompted participants to stand and engage in short bouts of office-based physical activity by interrupting prolonged occupational sitting time periodically throughout the workday. Mean arterial pressure was measured at pretest and posttest. <b>Results:</b> Between pretest and posttest the experimental group significantly reduced their MAP, whereas MAP in the control group did not. <b>Conclusions:</b> A workplace e-health intervention designed to reduce prolonged occupational sitting was effective in decreasing MAP in desk-based employees.
