对汽车制造企业 70 6名噪声作业工人 (噪声暴露组40 7例 ,对照组 2 99例 ) ,用横断面流行病学方法 ,采用健康监护、现场噪声测试、实验室检测等进行汽车制造业工人噪声暴露与高血压发病关系的探讨。结果显示 ,高血压患病率在噪声暴露组为 2 7 2 7% ,明显高于对照组 (18 0 6% ) ,两组比较 ,差异有显著性 (P <0 0 1)。随着累积噪声暴露水平的升高 ,高血压患病率呈增高趋势 ,且存在剂量 反应关系。Logistic回归分析结果表明 ,在控制了年龄、家族史和体重指数等混杂因素后 ,累积噪声暴露量是高血压发病的危险因素。 A total of 70 6 noise workers (40 7 noise exposure groups and 2 99 control groups) were exposed to automobile manufacturing enterprises. The workers in the automobile manufacturing industry were employed by means of cross-sectional epidemiology, health monitoring, on-site noise tests and laboratory tests Discussion on the relationship between noise exposure and hypertension. The results showed that the prevalence of hypertension in the noise exposure group was 27 72%, significantly higher than that in the control group (18 0 6%). There was significant difference between the two groups (P <0.01). With the increase of cumulative noise exposure, the prevalence of hypertension shows an increasing trend, and there is dose-response relationship. Logistic regression analysis showed that cumulative noise exposure was a risk factor for hypertension after controlling for confounding factors such as age, family history and body mass index.
