Insights

Children with iron deficiency anemia (IDA) have a significantly higher risk of developing sudden sensorineural hearing loss (SNHL). Early screening and treatment of IDA in pediatric patients may improve overall health outcomes.

Area of Science:

  • Pediatric audiology
  • Hematology
  • Public health

Background:

  • Iron deficiency anemia (IDA) is a common condition in children.
  • A link between IDA and sudden sensorineural hearing loss (SNHL) has been observed in adults.
  • The relationship between IDA and hearing loss in pediatric populations requires further investigation.

Purpose of the Study:

  • To investigate the association between iron deficiency anemia (IDA) and hearing loss in children and adolescents.
  • To determine if IDA increases the risk of sudden sensorineural hearing loss (SNHL) in a pediatric cohort.

Main Methods:

  • Retrospective cohort study utilizing the Informatics for Integrating Biology and the Bedside database (2011-2016).
  • Included children and adolescents aged 4-21 years diagnosed with hearing loss or IDA.
  • IDA was identified by low hemoglobin and ferritin levels; hearing loss by ICD-9/10 codes.

Main Results:

  • The study analyzed data from 20,113 patients.
  • Prevalence of hearing loss was 3.0% in the IDA cohort versus 1.7% in the non-IDA cohort.
  • Children with IDA showed increased odds of developing SNHL (aOR: 3.67, 95% CI [1.60-7.30]).

Conclusions:

  • Pediatric patients with IDA have a greater likelihood of experiencing SNHL.
  • While IDA correction's impact on hearing outcomes needs more research, addressing IDA benefits children's health.
  • Screening for and treating IDA in children is recommended for improved health status.
