Dyslipidemia and its relationship with shift work in petrochemical workers

Shift work disrupts the circadian rhythm, threatens workers’ health, and increases the prevalence of cardiovascular diseases. The relationship between shift work, demographic factors, and the prevalence of dyslipidemia in petrochemical industry workers was examined. The study was carried out on 495 male workers in a petrochemical plant. To examine the indices of prevalence of dyslipidemia, serum levels of LDL, HDL, TG, and total cholesterol were measured. The data were analyzed using SPSS software version 25. The results showed that the prevalence of dyslipidemia was equal to 45.1% and abnormal relative frequencies of TG, HDL, LDL, and total cholesterol were 55.8%, 14.3%, 36.6%, and 46.7% respectively. Shift work had a significant relationship with dyslipidemia so that it alone increased the prevalence of dyslipidemia by 14% (OR = 1.14, 955 C.I = 0.9990–1.280) and taking all the variables into account, it increased dyslipidemia by 7.5% (OR = 1.075, 955 C.I = 1.052–1.098). The results showed that shift work had a significant relationship with the prevalence of dyslipidemia and increased the OR. Therefore, management of diet and proper work scheduling are among the efficient strategies to decrease the metabolic damages caused by dyslipidemia. •Evaluation of Dyslipidemia among workers of a petrochemical industry.•Shift work increased the prevalence of dyslipidemia.•Age and BMI increased OR of Dyslipidemia.
