摘要
本文在120名接触中低剂量噪声、未出现语频听损的工人中发现高频听力损伤42人(经年龄性别校正,患病率35.0%),累积噪声暴露量由<75dB(A)增加至>95dB(A)时,高频听力损伤患病率由6.3%上升至53.3%。用Logistic回归模型进一步观察到累积噪声暴露量增加1dB(A)时,调整后的OddsRatio为1.136(P=0.001),证实中低剂量噪声暴露与高频听力损伤之间存在剂量-反应关系,长期接触中低剂量噪声可在一定程度上引起高频听力损伤。
Forty two cases of high frequency noise induced hearing loss(HFNIHL,adjusted by age and sex)were found in 120 workers exposed to mid-low level noise with a prevalence at 35.0%,No case of low frequency noise induced hearing loss was found in the same population,An increase of the prevalence of HFNIHL from 6.3%to 53.3%was found with the cumulative noise exposure was increased from<75 dB(A).year to>95 dB(A).year,A logistic regression model was used to observe its dose-response relationship.It was demonstrated that the adjusted odds ratio for HFNIHL was 1.136 after 1 dB(A)increase of noise exposure which showed statistical significance(P=0.001).It suggested that there was a dose-response relationship between the mid-low level noise exposure and the HFNIHL.
