Insights
Certain risk factors significantly increase a child's risk for congenital or permanent childhood hearing loss. Prioritizing follow-up audiology care for at-risk infants is crucial for early detection and intervention.
Area of Science:
- Pediatrics
- Audiology
- Genetics
Background:
- Hearing loss is a common birth defect.
- Early identification and intervention are critical for child development.
- Risk factors for hearing loss in early childhood require further investigation.
Purpose of the Study:
- To examine the association between risk factors and early childhood hearing status.
- To assess audiologic care follow-up rates for children with hearing loss risk factors.
Main Methods:
- Retrospective data review of 115,039 children born between 2010-2012.
- Analysis of prevalence rates, odds ratios, and Fisher exact tests.
- Categorization of hearing status: normal hearing, congenital hearing loss, delayed-onset hearing loss.
Main Results:
- 90% of children had no risk factors; 99.9% had normal hearing by age 3.
- Of children with risk factors (10%), 96.3% had normal hearing by age 3.
- Congenital hearing loss affected 1.4%, permanent hearing loss 2.3% of those with risk factors.
- Highest risk factors for congenital impairment: neurodegenerative disorders, syndromes, congenital infections.
- Highest risk factors for permanent postnatal loss: congenital cytomegalovirus, syndromes, craniofacial anomalies.
Conclusions:
- Specific risk factors significantly elevate the risk of congenital or permanent childhood hearing loss.
- Prioritizing diagnostic follow-up testing for children with identified hearing loss risk factors is essential.
Purpose:
In this study, we examined the association between risk factors for hearing loss and early childhood hearing status (normal hearing, congenital hearing loss, or delayed-onset hearing loss). Follow-up rates of audiologic care following passed or referred birth screens for children with risk factors were also examined.
Method:
A retrospective data review was completed on 115,039 children born from 2010 to 2012. Data analyses included prevalence rates, odds ratios, and Fisher exact tests of statistical significance.
Results:
Ninety percent of children were born with no risk factors for hearing loss; of those, 99.9% demonstrated normal hearing by 3 years of age. Of the 10% of children born with risk factors, 96.3% demonstrated normal hearing by age 3, 1.4% presented with congenital hearing loss, and 2.3% demonstrated permanent hearing loss by age 3. Factors that placed children at the highest risk of congenital hearing impairment were neurodegenerative disorders, syndromes, and congenital infections. Factors that placed children at the highest risk of developing permanent postnatal hearing loss were congenital cytomegalovirus, syndromes, and craniofacial anomalies.
Conclusions:
Certain risk factors place a child at significantly greater risk of congenital hearing impairment or developing permanent hearing loss by age 3. Follow-up diagnostic testing should remain a priority for children with certain risk factors for hearing loss.
