摘要

Protein Energy Malnutrition (PEM) is a significant health concern affecting physical, sensory, and cognitive development. While moderate or severe PEM is associated with hearing loss, the effects of mild PEM remain understudied. We investigated the impact of mild PEM on peripheral and central auditory processing in children. 108 children aged 7–14 were divided into control and mild-PEM groups. Auditory tests included pure tone-, speech-, immittance-audiometry for peripheral hearing, and tests for binaural interaction, integration, auditory closure, temporal processing, and auditory working memory for central auditory processing. Mild-PEM did not significantly affect peripheral hearing sensitivity, but significant differences in central auditory processing were observed between groups. Children with PEM performed poorer in binaural interaction, auditory closure, and auditory working memory tasks. This study highlights the importance of investigating malnutrition’s impact on auditory function. Identifying specific auditory deficits associated with PEM can inform targeted interventions for holistic development in resource-limited settings.
