Relationship between Shift Work and Cardiovascular disease Risk Factors in workers referred to Occupational Medicine Center of Gonabad University of Medical Sciences

Background: There are many well-known biologic and anthropometric risk factor for developing cardiovascular 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 of CVD risk factors. Materials & Methods: This analytical cross-sectional study was done in Occupational Medicine Center of Gonabad University of Medical Sciences from April to December in ۲۰۲۱. A total of ۷۴۳ workers who referred for periodic health examination were selected by simple random sampling. Those workers with at least one year of work experience who had Satisfaction for participation were included to the study. Having congenital heart disease, heart failure, kidney disease, Taking drugs that increase blood pressure, blood lipid and sugar and pregnant women were excluded.  Demographic data, Physical examination and Blood cholesterol, triglyceride and glucose 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 version ۲۱ at a significant level of ۰.۰۵.  Results: Of total, ۷۳.۴% were men and ۴۷.۳% were shift workers. The mean (Standard Deviation) of age was ۳۳.۹ (۵.۰۷) among shift workers, and ۳۶.۳۲ (۵.۸۱) among Day-time workers. There was significant independent association between shift work and triglyceride (B=۷.۵, ۹۵%CI=۱.۰۲,۱.۲۱, P=۰.۰۳) and cholesterol (B=۷.۲, ۹۵%CI=۱.۱۲,۱.۲۲, P=۰.۰۲۸) values. Conclusion: The results of the present study showed that the concentration of blood triglycerides and cholesterol is higher in shift workers than day-time workers. Therefore, particular follow-up of shift workers should be recommended for screening and preventing cardiovascular risk factors
