To investigate the independent effects and interaction of smoking and shift work on anxiety, depression, and Comorbid Anxiety and Depressive symptoms (CAD) among steelworkers.
Steelworkers undergoing occupational health check-ups from March to September 2017 were studied. Anxiety, depressive symptoms and CAD were assessed using the SAS self-assessment questionnaire and the SDS self-assessment questionnaire. Basic information of workers, demographic characteristics, smoking, and shift data were collected using the Health Assessment Questionnaire. The shift-weighted index (WSI) and smoking index were analyzed for the dose-response relationship between them and the CAD; the WSI were grouped according to the Akaike information crite-rion. Logistic regression analyzed the relationship between smoking, shift work (WSI), and anxiety, depression, and CAD. And to explore the interactive effect of both on CAD.
A total of 3 657 workers were included in this study. The detection rates for anxiety, depression, and CAD were 28.63%, 27.15%, and 22.52%, respectively. WSI > 159 and a smoking index ≥ 200 were independent risk factors for these conditions. Smoking and shift work showed multiplicative and synergistic effects on CAD, with SI, RERI, and AP of 11.86 (8.54-16.47), 28.94 (8.42-49.47), and 0.89 (0.84-0.93), respectively.
Both smoking and shift work increase the risk of anxiety, depression, and their comorbidity. Their combined presence significantly elevates CAD risk in steelworkers. Proper health management measures are recommended to improve mental health.
