Risk of stuttering onset and persistence linked to early language skills: Results from the Generation R Study

Area of Science:

• Child development
• Speech-language pathology
• Linguistics

Background:

• The relationship between language skills and childhood stuttering is not fully understood.
• Previous research indicates varied associations between language abilities and stuttering.
• This study investigates early language skills and their link to stuttering onset and persistence.

Purpose of the Study:

• To evaluate the association between early language skills and the risk of stuttering onset.
• To determine if early language skills predict stuttering persistence.
• To utilize population-level data for robust analysis.

Main Methods:

• Prospective, population-based cohort study.
• Analysis of early-childhood language data from children aged 18-48 months.
• Parental-reported questionnaires assessed expressive and receptive language skills at five time points.

Main Results:

• Higher expressive and receptive language skills at 24 months were associated with a decreased risk of stuttering (OR 0.78, p < 0.01).
• No significant association was found between language skills at 18, 30, 36, or 48 months and stuttering persistence.
• The study highlights a specific window at 24 months for language-stuttering risk association.

Conclusions:

• Lower early language skills are associated with an increased risk of stuttering onset, supporting prior research.
• Early language skills do not appear to be associated with the persistence of stuttering.
• Clinicians should consider screening language skills in preschool children with recent stuttering onset.
