Abstract：Objective To explore the effect of workplace noise on the levels of blood glucose and blood lipid of miners in alarge state-owned coal mining enterprise. Methods Occupational health examination was conducted in workers of a large state-owned coal mining enterprise in Xintai City. 428 workers with long-term exposure to high nosie [82.8-100.1 LAeq dB(A)] were randomly collected as the observation group, while 506 workers with exposure to low nosie [53.9-71.0 LAeq dB(A)] served as the control group. The differences in blood glucose and blood lipid levels of the two groups were compared. Results The levels of serum glucose (GLU), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were higher in the observation group than in the control group ((5.32±0.79)mmol/L vs. (4.99±0.68) mmol/L, (4.72±0.82)mmol/L vs. (4.24±1.02) mmol/L, (1.67±1.31)mmol/L vs. (1.33±1.03) mmol/L, (1.41±0.30)mmol/L vs. (1.54±0.35) mmol/L, (2.79±0.68) mmol/L vs. (2.58±0.70)) mmol/L,showing statistically significant differences in serum GLU, TC, TG and LDL-C (all P＜0.05). The abnormal rates of serum GLU, TC, TG, HDL-C and LDL-C levels as well as the detection rate of fatty liver in the observation group were also higher than those in the control group, showing statistically significant differences (all P<0.05). The contents of serum GLU, TC, TG and LDL-C increased with the increasing working age, and the serum GLU, TC, TG, HDL-C and LDL-C levels showed statistically significant differences among different working age groups (all P<0.05). Conclusion Long-term exposure to high noise may be a risk factor for the elevated blood glucose and blood lipid levels of the coal miners.
