Effects of Sex and Age on the Brainstem Auditory Evoked Potentials(BAEP) / 中国医师杂志

ABSTRACT

Objective To study the effects of sex and age on the Brainstem Auditory Evoked Potentials(BAEP).Methods 53 normal subjects' BAEP(106 ears) were examed.Multiple liner correlation and stepwise regression were used for statistical analysis.Results Wave Ⅲ latency and Ⅰ-Ⅲ,Ⅲ-Ⅴ interpeak latencies had correlation with age.All latencies and interpeak latencies(except Ⅰ-Ⅲ) had correlation with sex.All latencies and interpeak latencies were shorter in female than in male,for wave Ⅴ,this phenomenon was particularly obvious.Wave Ⅴ latency was about 0.2ms shorter in female than that in male.Conclusions Sex and age are major physiological factors on BAEP.If we pay colse attention to them in clinical application,the diagnosis is more objective and accurate.
