简介:摘要目的探讨不同版本诊断标准对疑似职业性噪声聋(occupational noise-induced deafness,ONID)诊断结果的影响,为ONID诊断标准的修订提供理论依据。方法于2019年9月回顾性调查2016年1月至2018年1月在清远市职业病防治院进行职业健康检查的在岗期间噪声作业工人的体检结果,以GBZ 49-2014《职业性噪声聋的诊断》标准判断为疑似ONID的471例劳动者为研究对象,加权不同组合高频听阈,计算较好耳加权值,分别与2007版、2014版诊断标准进行比较并判断听力损失程度。采用SPSS 22.0进行统计分析,计数资料用χ2检验,计量偏态资料用非参数检验方法进行统计推断并比较其差异性。结果471名研究对象平均年龄(40.32±7.01)岁;接触噪声作业工龄3~29年,平均(7.11±3.44)年。以2007版诊断标准进行诊断,加权不同高频听阈值与单纯语频均值疑似ONID诊断率差值两两比较,加权不同高频听阈值后,与语频均值诊断率差值比较,3.0 kHz高频增加了16.35%、4.0 kHz高频增加了30.15%、6.0 kHz高频增加了20.17%、3.0 kHz+4.0 kHz高频增加了22.29%、3.0 kHz+6.0 kHz高频加增加了17.20%、4.0 kHz+6.0 kHz高频增加了25.27%、3.0 kHz+4.0 kHz+6.0 kHz高频增加了22.29%,差异均有统计学意义(P<0.05)。以2014版诊断标准进行诊断,语频均值及加权不同高频听阈值疑似ONID诊断率,与4.0 kHz高频诊断率比较,语频均值降低了30.15%、3.0 kHz高频降低了13.80%、6.0 kHz高频降低了9.98%、3.0 kHz+4.0 kHz高频降低了7.86%、3.0 kHz+6.0 kHz高频降低了12.95%、4.0 kHz+6.0 kHz高频降低了4.88%、3.0 kHz+4.0 kHz+6.0 kHz高频降低了7.86%,差异均有统计学意义(P<0.05)。结论加权不同高频听阈值增加了疑似ONID的诊断率,其中加权4.0 kHz高频对结果的影响最大,加权3.0 kHz高频影响最小。
