Gender disparities in speech-evoked auditory brainstem response (speech-ABR) outcomes have been reported, but the literature is limited. The present study was performed to further verify this issue and determine the influence of head size on speech-ABR results between genders.
Twenty-nine healthy Malaysian subjects (14 males and 15 females) aged 19 to 30 years participated in this study. After measuring the head circumference, speech-ABR was recorded by using synthesized syllable /da/ from the right ear of each participant. Speech-ABR peaks amplitudes, peaks latencies, and composite onset measures were computed and analyzed.
Significant gender disparities were noted in the transient component but not in the sustained component of speech-ABR. Statistically higher V/A amplitudes and less steeper V/A slopes were found in females. These gender differences were partially affected after controlling for the head size.
Head size is not the main contributing factor for gender disparities in speech-ABR outcomes. Gender-specific normative data can be useful when recording speech-ABR for clinical purposes.
已有关于言语诱发听觉脑干反应（言语ABR）结果中性别差异的报道，但相关文献有限。本研究旨在进一步验证这一问题，并确定头围大小对不同性别言语ABR结果的影响。
29名年龄在19至30岁之间的健康马来西亚受试者（14名男性和15名女性）参与了本研究。测量头围后，使用合成音节/da/从每位参与者的右耳记录言语ABR。计算并分析言语ABR的波峰振幅、波峰潜伏期和复合起始测量值。
在言语ABR的瞬态成分中发现了显著的性别差异，但在持续成分中未发现。女性的V/A振幅在统计学上更高，V/A斜率更平缓。在控制头围大小后，这些性别差异受到了部分影响。
头围大小不是言语ABR结果中性别差异的主要影响因素。在临床记录言语ABR时，特定性别的规范数据可能会有所帮助。
