Background and Objectives: shift work as a pervasive phenomenon in various sectors of industry is one of the most stressful factors in workplace. Regarding contradictory studies about the relationship between shift work and hypertension, the main goal of the present study was to investigate the relationship between these two variables among petrochemical industry staff of Mahshahr, Iran.                                                                                                                                                  
Methods: In this longitudinal study, 3254 petrochemical staff was investigated during 2008-2011. According to work schedule, shift workers were divided into two groups shift work and day work (1872 day workers and 1382 shift workers). The aim of this research was to assess the effects of shift work on hypertension by adjusting confounding variables such as gender, age, body mass index, and smoking. The data were analyzed using a random-effects logistic regression model.                                                                                                                           
Results: Among 3254 (3142 males and 112 females) subjects, 37.85% (860 subject) were hypertensive. Fitting the random effects model, by controlling covariates, no significant relationship was found between shift work and presence of hypertension (OR=1.04, 95% CI= (0.98, 1.10). Also, the variance of the random effects was significant. 
Conclusion: Generally, according to obtained results in this study, shift work was not a significant risk factor for hypertension.
