Childhood speech disorders: Reported prevalence, comorbidity and socioeconomic profile

Abstract

Objective: To describe the reported prevalence, comorbidity and socioeconomic status (SES) of children with speech disorders. Methodology: Data from the 1995 Australian Health Survey were used. Information relating to the health of 12 388 children aged 0-14 years was collected via face-to-face interviews with a responsible adult. Speech disorders were recorded if children had reported difficulty talking, producing speech sounds, or who stuttered. Results: The prevalence of childhood speech disorders (CSD) was 1.7% (n = 209). Of this group, 25.8% (n = 54) had a developmental delay or intellectual impairment; when these were excluded, the prevalence of CSD was reduced to 1.3% (n = 155). Among males, the peak prevalence occurred at age 5 (6.5%), for females the highest rates were for 3-4-year-olds (1.8%). Children with a speech disorder had a greater number of additional health problems. No relationship was found between SES and CSD. Conclusions: Children with speech disorders often have complex health and developmental needs. Developing effective prevention programs with a view to improving the long-term health and social outcomes of these children will require a mix of individual (clinical) and population-based (public-health) strategies.
