目的:探索噪声作业工人高频听阈与高血压的关系。方法:对2011年某车身厂噪声作业工人定期体检数据进行分析。在工人脱离噪声16h后检测纯音听阈,同时进行血压测量。调查对象分为高频听损组(高频听阈≥40db)和正常对照组(高频听阈<40db)。两组人群高血压患病率的比较采用卡方检验;两组和多组人群收缩压、舒张压的比较分别采用t检验和方差分析。统计软件采用SPSS15.0。结果:高频听损组高血压患病率为28.2%,高于对照组的21.4%(卡方值=11.685,P=0.001);高频听损组的收缩压和舒张压缩压(124.6mmHg,82.3mmHg),均高于对照组(121.8mmHg,80.1mmHg)(P<0.01)。高频听阈超过40db后,高血压患病率和血压值并不随高频听阈的上升而继续上升。结论:高频听阈与高血压患病率及血压值有着密切联系,其变化规律需要深入研究。
Objective: To explore the relationship between high frequency hearing threshold and hypertension in noise workers. Methods: The data of regular medical examination of workers exposed to noise in a body factory in 2011 were analyzed. The pure tone hearing threshold was measured after the worker left the noise for 16 hours and the blood pressure was measured at the same time. Subjects were divided into high-frequency hearing loss group (high-frequency hearing threshold ≥ 40db) and normal control group (high-frequency hearing threshold <40db). The prevalence of hypertension among the two groups was compared using the chi-square test; t-test and ANOVA were used to compare the systolic and diastolic blood pressure in two and more groups. Statistical software using SPSS15.0. Results: The prevalence of hypertension in high-frequency hearing loss group was 28.2%, higher than 21.4% in the control group (Chi square = 11.685, P = 0.001). The systolic and diastolic blood pressure (124.6mmHg , 82.3mmHg) were higher than the control group (121.8mmHg, 80.1mmHg) (P <0.01). High-frequency hearing threshold of more than 40db, the prevalence of hypertension and blood pressure does not rise with the high-frequency hearing threshold and continue to rise. Conclusion: The high frequency hearing threshold is closely related to the prevalence of hypertension and blood pressure, and its variation needs further study.
