Abstract:
Objective:To analyze the effects of shift work on the renal function of oil workers and investigate whether there is a measured response relationship between shift work and renal dysfunction.Methods:In this study, oil workers who participated in physical examinations at the North China Oilfield Downhole Hospital were selected as the study subjects, and the physical examinations as well as questionnaires of the study subjects in 2017 and 2018 were collected as the baseline data, which included blood biochemical indexes, socio-demographic characteristics, history of life behaviors, occupational exposures, and occupational histories. Three follow-up surveys were subsequently conducted in April 2019, April 2020, and January 2021. The presence of renal dysfunction in the study population was determined based on the glomerular filtration rate tested at the medical examination hospital. The exposure of the study subjects to shift work was assessed using the weighted shift index (WSI), the relationship between different levels of shift work and renal dysfunction was analyzed using Cox regression, and the measure of WSI and renal dysfunction was explored by restricted cubic spline (RCS). response relationship.Results:A total of 2292 study participants were included in this study, and the prevalence density of renal dysfunction was 87.44 k/year, of which the prevalence of renal dysfunction in females (30.31%), those with per capita monthly income <2, 000 yuan (27.00%), those who consume alcohol (27.10%), those who are hypertensive (23.05%), those who are exposed to high temperatures (27.37%), those who are exposed to organic solvents (30.42%), and those who are engaged in shift work (25.87%) were to be found had a higher prevalence of renal dysfunction ( P<0.05). After correcting for age, sex, and other risk factors, there was a nonlinear association between intensity of shift work and renal dysfunction, with a hazard ratio ( HR) of 1.29 (95% CI: 0.98-1.59) for the development of renal dysfunction in petroleum workers for shift work performed at higher intensities, and moderate intensity of exposure to shift work reduced the risk of renal dysfunction in petroleum workers ( HR=0.54 with a 95% CI: 0.39-0.75, P<0.001) . Conclusion:Prolonged shift work increases the risk of renal dysfunction in oil workers, and the occurrence of renal dysfunction in oil workers is influenced by multiple factors.
