Abstract:Objective To study the effect of occupational noise exposure on employees′ blood pressure by analyzing the health examination data of employees in an aircraft manufacturing enterprise,and provide a theoretical basis for the prevention and control of cardiovascular diseases in noise-exposed employees.Methods A cross-sectional survey method was used to collect information on the health and noise exposure of 2097 employees from an aircraft manufacturing enterprise from March to August 2015,and the impact of noise exposure on employees′ blood pressure was analyzed.Results The prevalence of hypertension among employees was 36.8%(772/2097).The prevalence of hypertension among employees in the noise-exposed group was higher than that in the non-noise-exposed group,the difference was statistically significant(39.9% vs. 32.9%,χ2=10.935, P=0.001).The systolic blood pressure of the noiseexposed group and the non-noise-exposed group were(134.34±18.14)and(130.37±18.48)mmHg,respectively,and the diastolic blood pressure was(82.87±13.33)and(81.17±12.81)mmHg,respectively.The systolic and diastolic blood pressures of the employees in the noise-exposed group were higher than those in the non-noise-exposed group,and the differences were statistically significant(P<0.05).Conclusion Noise-exposed employees have a high prevalence of hypertension.The targeted primary prevention on this population should be emphasized.
