Background and Aim:  Shift work may induce adverse effects such as health problems on human life. The purpose of this study was to investigate shift work-related health problems and their associated risk factors among workers of petrochemical industries.

Materials and Methods: This cross-sectional study was carried out in 21 petrochemical companies affiliated to the National Petrochemical Industries Company, Iran. The study population consisted of 3580 workers (44.2% shift- and 55.8% day-workers). Data were collected on demographic characteristics, shift schedules, and health problems using anonymous questionnaires. Statistical analyses and modeling were performed using SPSS version 11.5.

Results: The mean age of the day-workers with a job tenure of 8.87±7.22 years and of the shift-workers with a job tenure of 8.22±7.02 years was 34.56±8.19 and 33.15±7.73 years, respectively. Analysis of the data showed that prevalence of health problems among shift-workers was higher than that of day-workers. Furthermore, based on multiple linear regression analysis, it was revealed that, in addition to shift-working itself, other variables such as long working-hours, type of employment, age, job tenure, education, and job title also had a role in creating problems.             

Conclusion: Although in the shift-working system the main risk factor associated with health problems among the workers is the work itself, there are also other risk factors, such as demographic and occupational variables.
