Relationship Between Shift Work and Cardiovasculardisease Risk Factors in Workers Referred to OccupationalMedicine Center of Gonabad University of MedicalSciences

Background: there are many well-known biologic and anthropometric risk factor for developingcardiovascular diseases (cvd). shift work (sw) may be associated with cvd risk factors.objectives: this study was performed to investigate the relationship of shift work and some ofcvd risk factors.materials & methods: this analytical cross-sectional study was done in occupational medicinecenter of gonabad university of medical sciences from april to december in 2021. a totalof 743 workers who referred for periodic health examination were selected by simple randomsampling. those workers with at least one year of work experience who had satisfaction forparticipation were included to the study. having congenital heart disease, heart failure, kidneydisease, taking drugs that increase blood pressure, blood lipid and sugar and pregnant womenwere excluded. demographic data, physical examination and blood cholesterol, triglyceride andglucose measures were collected. data analysis was performed using mann–whitney u test,student t-test, chi-square and multivariate linear regression model with spss software version21 at a significant level of 0.05.results: of total, 73.4% were men and 47.3% were shift workers. the mean±standarddeviation of age was 33.9±5.07 among shift workers, and 36.32±5.81 among day-time workers.there was significant independent association between shift work and triglyceride (b=7.5,95%ci=1.02,1.21, p=0.03) and cholesterol (b=7.2, 95%ci=1.12,1.22, p=0.028) values.conclusion: the results of the present study showed that the concentration of blood triglycerides and cholesterol is higher in shiftworkers than day-time workers. therefore, particular follow-up of shift workers should be recommended for screening and preventingcardiovascular risk factors.
