目的观察噪声对职业机动车驾驶员(以下简称驾驶员)血压的影响。方法测定2011—2012年来肇庆市疾病预防控制中心进行职业健康监护的620名驾驶员的血压和纯音测听,与对照组(460名)进行比较,以及根据不同工龄进行驾驶员组内比较,进行统计学分析。结果接触噪声的驾驶员高血压患病率(27.4%)与对照组(16.1%)患病率差异有统计学意义(χ2=19.39,P<0.01);驾驶员的感音性听力损失也明显高于对照组,差异出有统计学意义(χ2=19.13,P<0.01);随着作业工龄的延长,驾驶员的感音性听力损失和高血压发病率明显增高,各年龄组间患病率差异有统计学意义(χ2=27.39和χ2=19.16,均P<0.01)。结论噪声能导致驾驶员高血压患病率增高。
Objective To observe the effect of noise on the blood pressure of a professional motor vehicle driver (hereinafter referred to as driver). Methods The blood pressure and pure tone audiometry of 620 drivers taking occupational health care in Zhaoqing CDC from 2011 to 2012 were measured and compared with the control group (460 subjects), and the driver group was compared according to different seniority Statistical analysis. Results The prevalence of driver-induced hypertension (27.4%) was significantly different from that of the control group (16.1%) (χ2 = 19.39, P <0.01). The driver’s sensory hearing loss was also significant Higher than the control group, the difference was statistically significant (χ2 = 19.13, P <0.01); with extended service life, the driver’s sensorial hearing loss and hypertension significantly increased the prevalence of illness among all age groups The difference was statistically significant (χ2 = 27.39 and χ2 = 19.16, both P <0.01). Conclusion Noise can lead to an increased prevalence of driver hypertension.
