The Prevalence of Speech and Language Disorders in French-Speaking Preschool Children From Yaoundé (Cameroon)

Purpose

The purpose of this study was to determine the prevalence of speech and language disorders in French-speaking preschool-age children in Yaoundé, the capital city of Cameroon.

Method

A total of 460 participants aged 3–5 years were recruited from the 7 communes of Yaoundé using a 2-stage cluster sampling method. Speech and language assessment was undertaken using a standardized speech and language test, the Evaluation du Langage Oral (Khomsi, 2001), which was purposefully renormed on the sample. A predetermined cutoff of 2 SDs below the normative mean was applied to identify articulation, expressive language, and receptive language disorders. Fluency and voice disorders were identified using clinical judgment by a speech-language pathologist.

Results

Overall prevalence was calculated as follows: speech disorders, 14.7%; language disorders, 4.3%; and speech and language disorders, 17.1%. In terms of disorders, prevalence findings were as follows: articulation disorders, 3.6%; expressive language disorders, 1.3%; receptive language disorders, 3%; fluency disorders, 8.4%; and voice disorders, 3.6%.

Conclusion

Prevalence figures are higher than those reported for other countries and emphasize the urgent need to develop speech and language services for the Cameroonian population.
