摘要
调查接触纺织噪声强度为72～104dB(A)的1174名纺织工人的血压和心率,结果发现其高血压病(含临界高血压)患病率为11.33％,心率异常患病率为6.56％,均显著高于对照组,且与噪声强度及工龄呈正相关。其特征是:(1)噪声组直线回归高于对照组,两组回归系数有显著性差异。(2)噪声组的高血压病病例开始出现在较年轻组。30～39岁组高血压病患病率已显著高于对照组,并随年龄增长而增高。表明噪声接触者发生高血压病的危险性较大。
One thousand one hundred and seventy-four workers expososed to textile industrial noise of 72～104 dB (A) noise level were examined in this epidemiological survey. It was found that 11.33％ of these workers were hypertension(including borderline hypertenslon)and 6.56％ were of abnormal heart rate, including tachycardiac and bradycardiac, all significantly different from those of the control group. There were positive relations between hypertension morbidity and noise level, and length of exposure, indicating exposure-response relationship. Also there was a direct association between hypertension and age. The characteristics are: (1) Linear regresson coefficient of the noise group was higher than that of the control group, indicating that those Subjects exposed to noise had a significantly greater risk of developing hypertension. (2) Hypertension appeared at relatively young ages(30～39 years) and increased with age. This study emphasize the need for, at least annually, periodic examination of the persons with exposure to textile industrial noise in order to detect early adverse effects in cardiovascular system and to consider medical care.
