Prevalence of stuttering in African American preschoolers.
OBJECTIVE
In this study, the authors sought to determine the prevalence of stuttering in African American (AA) 2- to 5-year-olds as compared with same-age European Americans (EAs).


METHODS
A total of 3,164 children participated: 2,223 AAs and 941 EAs. Data were collected using a 3-pronged approach that included investigators' individual interactions with each child, teacher identification, and parent identification of stuttering.


RESULTS
No statistically significant difference for stuttering was found between AA and EA children. Using the investigator and teacher method of identification, the prevalence of stuttering was 2.52% for the entire sample. For both racial groups, boys exhibited a higher prevalence of stuttering than girls. Of the 3 predictors (age, race, sex) of stuttering, only sex was a significant predictor.


CONCLUSIONS
AA 2- to 5-year-olds are not overrepresented in the stuttering population for this age group. When data are combined for both racial groups, the prevalence of stuttering is 2.52%. More boys than girls stuttered in this sample of preschoolers.
