Population Health in Pediatric Speech and Language Disorders: Available Data Sources and a Research Agenda for the Field

Purpose

The aim of the study was to provide an overview of population science as applied to speech and language disorders, illustrate data sources, and advance a research agenda on the epidemiology of these conditions.

Method

Computer-aided database searches were performed to identify key national surveys and other sources of data necessary to establish the incidence, prevalence, and course and outcome of speech and language disorders. This article also summarizes a research agenda that could enhance our understanding of the epidemiology of these disorders.

Results

Although the data yielded estimates of prevalence and incidence for speech and language disorders, existing sources of data are inadequate to establish reliable rates of incidence, prevalence, and outcomes for speech and language disorders at the population level.

Conclusions

Greater support for inclusion of speech and language disorder–relevant questions is necessary in national health surveys to build the population science in the field.
