Abstract
Background: Regarding the high prevalence of obesity and cardiovascular diseases in people, especially worker population, and the problems caused by these diseases, this study aimed to evaluate the effect of work shift (day, night, and rotate shift workers) on blood pressure and body mass index (BMI).Methods: In this cross-sectional study, 6983 employees who referred to the occupational centers of the city of Isfahan, Iran, in 2015, participated according to inclusion and exclusion criteria. They were divided into two groups based on type of work as official and non-official and three groups based on work shift: day, fixed night, and rotate shift working. Age, systolic and diastolic blood pressure, body mass index, and occupational type were compared between these groups.Findings: 82.2%, 0.7%, and 17.1% of participants were day, fixed night, and rotate shift workers, respectively. There was a significant difference between the groups in age and type of occupation (P < 0.001 for both); but there was no significant difference between the groups regarding systolic and diastolic blood pressure, and body mass index (P > 0.050 for all).Conclusion: The results of this study indicate that shift work has no effect on the level of blood pressure and body mass index.
