Purpose: 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).

Method: 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.

KEY WORDS: African American, preschoolers, stuttering, prevalence, children
