目的探讨机械加工企业职业噪声暴露与高血压的发病关系。方法对噪声作业场所进行现场噪声测定,对噪声从业人员进行现场调查。结果机械加工企业噪声从业人员高血压患病率为12.1%。随着累积噪声暴露量(CNE)的增加高血压患病率逐渐升高(趋势x2=29.932,P< 0.01),高血压患病率与CNE之间存在明显的剂量反应关系。非条件logistic回归分析结果显示:在校正了年龄、体重指数和高血压家族史等影响因素的干扰后,CNE每增加1 dB(A),噪声从业人员其高血压发病的危险增加5%(OR=1.047)。结论噪声暴露可能是高血压发病的一个危险因素,降低作业场所的噪声强度可能是减少机械加工企业噪声从业人员高血压发病的有效措施。
Objective To explore the relationship between occupational noise exposure and hypertension in mechanical processing enterprises. Methods Noise measurement site noise measurement, on-site survey of noise practitioners. Results The prevalence of hypertension in mechanical processing enterprises was 12.1%. With the increase of cumulative noise exposure (CNE), the prevalence of hypertension increased gradually (trend x2 = 29.932, P <0.01). There was a significant dose-response relationship between the prevalence of hypertension and CNE. The results of unconditional logistic regression analysis showed that for every 1 dB (A) increment of CNE, the risk of hypertension among noise practitioners increased by 5% after correcting the interference of influencing factors such as age, body mass index and family history of hypertension (OR = 1.047). Conclusion Noise exposure may be a risk factor for the development of hypertension. To reduce the noise intensity in the workplace may be an effective measure to reduce the incidence of hypertension among noise workers in the machining enterprises.
