Association between abnormal renal function and sleep among male coal workers in Xingtai City

Abstract

Objective To explore the relationship between sleep duration, insomnia, shift work and kidney function among male coal workers in Xingtai City, and to provide a theoretical basis for the prevention and treatment of kidney diseases in male coal workers. Methods A cross-sectional study was uesd. Relevant information was collected through questionnaires and blood biochemical analysis. Mutiple Logistic regression model was used to explore the relationship between abnormal renal function and sleep, night shift work. Results The prevalence of abnormal renal function among male workers in coal enterprises was 5.3%. The proportion of individuals with night shift work, sleep duration ≤5 h and insomnia were 63.2%, 4.0%, and 10.0% respectively. After adjusting for age, sleep duration, shift work and and insomnia, the results of multivariate Logistic regression analysis model showed that the relationship between shift work (OR=1.557, 95% CI: 1.078-2.250, P=0.018), sleep duration ≤ 5 h (OR=1.886, 95% CI: 1.005-3.540, P=0.048), group with sleep problems (OR=1.810, 95% CI: 1.286-2.546, P=0.001) and abnormal renal function was attenuated. The relationship between insomnia and abnormal renal function was not statistically significant (P=0.279). According to the stratified analysis of the shift work, after adjusting the related abnormal renal function among shift workers (Ptrend=0.001). Conclusions Sleep and shift work independently associate with abnormal renal function in male coal workers. The risk of abnormal kidney function increases with the severity of sleep problems.
