Prevalence of stuttering

Area of Science:

• Speech and Hearing Sciences
• Neurodevelopmental Disorders
• Genetics and Epidemiology

Background:

• Stuttering (also known as stammering) is a complex speech disorder.
• Previous research indicates potential genetic and neurological underpinnings.
• Understanding prevalence and risk factors in specific populations is crucial for intervention.

Purpose of the Study:

• To determine the prevalence of stuttering in a university population.
• To investigate demographic factors (gender, handedness) and family history in relation to stuttering.
• To highlight the need for further research into the etiology of stuttering.

Main Methods:

• A survey-based study was conducted on a university student population.
• Data collected included self-reported stuttering status, gender, handedness, and family history of stuttering.
• Prevalence rates and correlations were analyzed.

Main Results:

• The prevalence of current stuttering was 2.1%, with 3.4% identified as former stutterers.
• Males exhibited a higher prevalence of stuttering compared to females.
• A family history of stuttering was reported across current, former, and questionable stutterer groups.
• Right-handed females were less likely to have recovered from stuttering than right-handed males.

Conclusions:

• Stuttering remains prevalent in young adults, particularly males.
• The consistent family history across stuttering groups suggests a strong genetic component.
• Findings underscore the necessity of investigating organic causes for stuttering, despite advancements in speech therapy.
