Abstract

Background:  South Africa shows a high prevalence of type 2 diabetes with reported association with auditory dysfunction.

Objectives:  To describe the audiological profile of adults with this metabolic condition.

Method:  Employing a descriptive research design, 35 individuals with type 2 diabetes, selected through purposive sampling, underwent a basic audiological assessment in addition to extended high-frequency (EHF) audiometry, distortion product otoacoustic emissions (DPOAE) testing and neurological auditory brainstem response (ABR) test.

Results:  This study revealed a 31.4% prevalence of hearing loss with 81.8% being sensorineural in nature. Poor hearing thresholds were observed at 16 kHz (n = 19; 54.3%), 18 kHz (n = 24; 68.6%) and 20 kHz (n = 30; 85.7%) in the right ear and at 16 kHz (n = 20; 57.1%), 18 kHz (n = 24; 68.6%) and 20 kHz (n = 30; 85.7%) in the left ear. Absent DPOAEs were observed at 6 kHz (n = 20; 51.7%) and 8 kHz (n = 24; 68.6%) in the right ear and at 6 kHz (n = 17; 48.6%) and 8 kHz (n = 29; 82.9%) in the left ear, possibly indicating that type 2 diabetes specifically targets higher frequency hearing. The ABR results revealed a delayed absolute latency of wave III bilaterally (right ear -69%; left ear - 51%), suggesting an impact of this metabolic disease on retro-cochlear pathways.

Conclusion:  Hearing loss should be recognised as a comorbidity accompanying type 2 diabetes, which indicates the need for routine comprehensive audiological assessments to facilitate early detection and intervention.Contribution: The present findings have implications for audiology clinical protocols; diabetes related health policies and patient education.

2 型糖尿病患者的听力概况。
背景:南非的 2 型糖尿病发病率很高,据报道与听觉功能障碍有关: 南非的 2 型糖尿病发病率很高,据报道与听觉功能障碍有关: 方法:采用描述性研究设计,有目的性地挑选了 35 名 2 型糖尿病患者,对他们进行听觉功能测试: 方法:采用描述性研究设计,通过目的性抽样选出 35 名 2 型糖尿病患者,对其进行基本听力评估,此外还进行了扩展高频(EHF)测听、失真产物耳声发射(DPOAE)测试和神经听觉脑干反应(ABR)测试: 研究结果显示,听力损失发生率为 31.4%,其中 81.8% 为感音神经性听力损失。右耳在 16 kHz (n = 19; 54.3%)、18 kHz (n = 24; 68.6%) 和 20 kHz (n = 30; 85.7%) 频率下的听阈较低,左耳在 16 kHz (n = 20; 57.1%)、18 kHz (n = 24; 68.6%) 和 20 kHz (n = 30; 85.7%) 频率下的听阈较低。在右耳 6 kHz(n = 20;51.7%)和 8 kHz(n = 24;68.6%)以及左耳 6 kHz(n = 17;48.6%)和 8 kHz(n = 29;82.9%)处观察到无 DPOAE,这可能表明 2 型糖尿病特别针对高频听力。ABR结果显示,双侧第III波的绝对潜伏期延迟(右耳-69%;左耳-51%),表明这种代谢性疾病对耳蜗后通路有影响: 结论:听力损失应被视为 2 型糖尿病的并发症之一,这表明有必要进行常规全面听力评估,以便及早发现和干预:本研究结果对听力学临床方案、糖尿病相关健康政策和患者教育具有重要意义。
