Summary

White infants showed higher rates of middle ear dysfunction compared to Black infants in initial screenings. This racial disparity persisted even after retesting, indicating a significant difference in middle ear health between the two groups.

Background:

Middle ear dysfunction is a common concern in infants.
Early identification and management are crucial for developmental outcomes.
Racial and ethnic variations in health conditions are increasingly recognized.

Purpose of the Study:

To investigate racial differences in middle ear dysfunction among infants.
To compare tympanometry screening results between Black and White infants.
To assess the persistence of any observed racial disparities over time.

Main Methods:

Infants aged 6-13 months were screened using tympanometry.
Participants included Black (N=63) and White (N=74) infants.
Infants who failed initial screening were retested after a 6-week interval.

Main Results:

A significantly higher percentage of White infants (57%) failed the initial screening compared to Black infants (33%).
While overall failure rates decreased upon retesting, the significant racial difference in failure rates was maintained.
The observed racial effect on middle ear dysfunction was statistically significant (p < .05).

Conclusions:

Significant racial disparities exist in middle ear dysfunction among infants.
Tympanometry screening reveals higher prevalence in White infants compared to Black infants.
These findings have implications for clinical practice and targeted screening strategies.
