Factors that increase the risk of stuttering include:

  • Having relatives who stutter. Stuttering tends to run in families.
  • Delayed childhood development. Children who have developmental delays or other speech problems may be more likely to stutter.
  • Being male. Males are much more likely to stutter than females are.
  • Stress. Stress in the family, high parental expectations or other types of pressure can worsen existing stuttering.
