Abstract :
Several factors affect the emergence of high blood pressure, among
which include environmental and occupational factors. Shift work is
currently a commonly used program at workplaces. The purpose of this
study was to determine the impact of shift work on blood pressure
changes. The data used in this retrospective cohort study was collected
using annual observations conducted in the Diseases Follow-up Unit,
Industrial Medicine Unit of the Occupational Health Center of the
Mobarakeh Steel company from 2007 to 2010. In this study, the effect of
shift work on systolic and diastolic blood pressure changes were
analyzed by controlling for the body mass index (BMI), age, and
educational levels using multilevel models. This study included 5,351
people (45.2% on the day shift, 6% on the weekly rotation shift, and
48.8% on a normal rotation shift). 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). According to the
results of this study, it seems that shift work can be considered a risk
factor for high blood pressure changes. It is recommended that workers
who are working in shifts are more at risk and need more
supervision.
