Summary

Iron-deficiency anemia in infants did not show significant auditory dysfunction via brainstem auditory-evoked potentials. Auditory function remained unchanged after iron therapy, suggesting moderate anemia may not impact hearing.

Area of Science:

Pediatrics
Neuroscience
Hematology

Background:

Iron-deficiency anemia can impact infant development, including mental and motor skills.
Brainstem auditory-evoked potentials (BAEPs) offer a noninvasive method to assess central nervous system auditory function.

Purpose of the Study:

To investigate the effects of iron-deficiency anemia on auditory functions in infants using BAEPs.
To evaluate changes in auditory function before and after iron supplementation.

Main Methods:

A case-control study involving 20 infants with iron-deficiency anemia and 20 healthy, age-matched controls.
Brainstem auditory-evoked potentials were recorded for all participants.
BAEPs were re-assessed in the iron-deficient group after 3 months of oral iron therapy.

Main Results:

No statistically significant differences were found in BAEPs between infants with iron-deficiency anemia and the control group.
No significant changes in BAEPs were observed in the iron-deficient group after oral iron therapy.

Conclusions:

Moderate iron-deficiency anemia in infants may not cause detectable auditory dysfunction via BAEPs.
The impact of severe iron-deficiency anemia on auditory function warrants further investigation.
