Area of Science:

  • Pediatrics
  • Developmental Psychology
  • Linguistics

Background:

  • Language delay affects preschool children globally, impacting academic and social development.
  • Early identification and intervention are crucial for mitigating long-term effects of language delay.
  • Prevalence rates of language delay can vary significantly across different linguistic and cultural groups.

Purpose of the Study:

  • To determine the incidence of language delay in 3-year-old Cantonese-speaking children in Hong Kong.
  • To differentiate between general language delay and specific language delay.
  • To explore potential gender-based differences in language delay prevalence.

Main Methods:

  • Stratified proportional sampling of 3-year-olds in Hong Kong.

  • Utilized the Developmental Language Screening Scale (DLSS) for initial screening.
  • Employed the Reynell Language Developmental Scale (RDLS) for clinical diagnosis in a subset of children.

    • Main Results:

    • Stage I screening identified 4% with comprehension delay, 2.8% with expression delay, and 3.3% with both.
    • Stage II diagnosis revealed a 3.4% overall language delay rate.
    • Specific language delay was identified in 3% of children.
    • A higher proportion of boys presented with language delay, but this difference was not statistically significant.

    Conclusions:

    • Language delay is a notable concern in Hong Kong's preschool population, affecting approximately 3-4% of 3-year-olds.
    • The study provides valuable data on the prevalence of language delay in a Cantonese-speaking context.
    • Further research is warranted to explore the non-significant gender difference and underlying causes.
