Abstract

Background: People with intellectual disabilities often have undetected hearing loss.

Methods: In this prospective observational study featuring 110 adults with intellectual disabilities, hearing evaluations based on objective hearing threshold estimation using distortion-product otoacoustic emission growth functions (DPOAEgfs) were performed in a sheltered workshop. Results were compared with thresholds obtained by conventional subjective pure-tone audiometry (cPTA) and the adaptive self-test PTA Multiple-Choice-Auditory-Graphical-Interactive-Check (MAGIC).

Results: The differences between the lowest thresholds obtained by cPTA and MAGIC for the frequencies 1, 2, 4 and 6 kHz (LPTATs) and the estimated distortion-product thresholds (EDPTs) were calculated. Four hundred twenty-seven of 880 (48.5%) pairs of measurements did not differ by any more than 5 dB. With LPTATs as reference criterion, for a favourable four-frequency average over 1.0, 2.0, 4.0 and 6.0 kHz with a cutoff of 20 dB HL, the sensitivity of the EDPTs was 92% and the specificity 62%; a cutoff of 30 dB HL increased the respective values to 98% and 77%.

Conclusions: DPOAEgfs are acceptable for estimating hearing thresholds in individuals with intellectual disability who may have limitations in performing conventional audiometry.

利用畸变积耳声发射生长函数估算智障人士的听力阈值。

背景：智力残疾者往往有未被发现的听力损失。方法：对110名智力残疾成人进行前瞻性观察研究，采用畸变积耳声发射生长函数（dpoagf）对客观听力阈值进行评估。将结果与传统主观纯音听力学（cPTA）和自适应自测PTA多项选择-听觉-图形-交互-检查（MAGIC）获得的阈值进行比较。结果：计算了cPTA和MAGIC在1、2、4和6 kHz频率下获得的最低阈值（LPTATs）与估计的失真乘积阈值（EDPTs）之间的差异。880对测量中有427对（48.5%）的差异不超过5 dB。以LPTATs为参考标准，对于1.0、2.0、4.0和6.0 kHz以上的有利四频平均值，截止值为20 dB HL， EDPTs的灵敏度为92%，特异性为62%；30 dB HL的截止值分别提高到98%和77%。结论：dpoagf可用于估计智力残疾患者的听力阈值，这些患者在进行常规听力测量时可能受到限制。

期刊介绍： The Journal of Intellectual Disability Research is devoted exclusively to the scientific study of intellectual disability and publishes papers reporting original observations in this field. The subject matter is broad and includes, but is not restricted to, findings from biological, educational, genetic, medical, psychiatric, psychological and sociological studies, and ethical, philosophical, and legal contributions that increase knowledge on the treatment and prevention of intellectual disability and of associated impairments and disabilities, and/or inform public policy and practice. Expert reviews on themes in which recent research has produced notable advances will be included. Such reviews will normally be by invitation.
