چکیده
Background: Several factors affect the emergence of high blood pressure, among which include environmental and occupationalfactors. Shift work is currently a commonly used program at workplaces.Objectives: The purpose of this study was to determine the impact of shift work on blood pressure changes.Patients and Methods: The data used in this retrospective cohort study was collected using annual observations conducted in theDiseases Follow-up Unit, Industrial Medicine Unit of the Occupational Health Center of the Mobarakeh Steel company from 2007to 2010. In this study, the effect of shift work on systolic and diastolic blood pressure changes were analyzed by controlling for thebody mass index (BMI), age, and educational levels using multilevel models.Results: This study included 5,351 people (45.2% on the day shift, 6% on the weekly rotation shift, and 48.8% on a normal rotationshift). By controlling the confounding factors, shift work showed a significant relationship with systolic blood pressure (P = 0.01)but failed to show any significant relationships with diastolic blood pressure (P = 0.08).Conclusions: According to the results of this study, it seems that shift work can be considered a risk factor for high blood pressurechanges. It is recommended that workers who are working in shifts are more at risk and need more supervision.
