Exploring the Relationship Between Rotating Shift Work, Excluding Night Shifts, and Metabolic Syndrome Among Automotive Industry Male Worke

Objective: In recent decades, the incidence of metabolic syndrome (MetS) has been increasing, driven by socio-economic development and rising living standards. Occupational factors, particularly shift work, are increasingly recognized as potential contributors to MetS. This study examines the connection between shift work and MetS among automotive industry workers. Methods: This cross-sectional study randomly selected 2332 male participants employed at an Iranian automobile company. The prevalence of MetS was evaluated using the National Cholesterol Education Program Adult Treatment Panel III criteria. Results: The study found a 16.2% prevalence of MetS, with no significant association between shift work and MetS (P = .930). However, multiple logistic regression analysis revealed that job category and body mass index (BMI) demonstrated a significant association with MetS, even after controlling for potential confounding variables. Conclusion: The study found that rotating shift work, not including night shifts, does not increase the risk of MetS compared to fixed shift work. However, job category and BMI were significantly linked to MetS. These findings suggest a need for further research and advocacy for targeted medical surveil lance and potential work schedule modifications to mitigate health risks.
