Introduction: The present study was performed in order to investigate the association between shift work and having second job, with quality of life in a large sample of male employees in Isfahan steel company adjusting for the effects of demographic, lifestyle and job stress confounders. Materials and Methods: This cross-sectional study was carried out on 3063 employees of Isfahan steel company, who were selected through a multistage cluster sampling among 16000 employees in 2016. Demographic and lifestyle data were obtained from a self-administered questionnaire. Relatively, for evaluating the quality of life (QoL), EQ-5D, for job stress, the Effort-Reward Imbalance (ERI) questionnaire and for physical activity IPAQ were used. Latent class regression was used for data analysis. Results: In study sample, 57.7% were shift workers and 10% had second job. Participants were classified into two classes, high (80.49%) and low (19.51%) QoL, and this variable was considered as the response variable in latent class regression. Shift workers had17% lower odds for being in high quality of life class in adjusted model (OR=0.83 95% CI: (0.683, 1.015)). No significant relationship was observed between second job and quality of life Conclusion: The present study showed that the shift workers has significant lower quality of life, while no significant association was found with the second job.
