This study found that males, non-right-handers, and individuals with left eye preference reported more learning difficulties. Certain health issues were also more prevalent in males and non-right-handers.

Area of Science:

  • Neuroscience
  • Human Development
  • Public Health

Background:

  • Laterality, including hand and eye preference, is a fundamental aspect of human neurodevelopment.
  • Previous research suggests potential links between atypical laterality and various developmental or health conditions.
  • Understanding these associations is crucial for identifying potential risk factors and informing interventions.

Purpose of the Study:

  • To investigate the relationship between self-reported hand and eye laterality.
  • To examine the association between laterality patterns and the prevalence of learning difficulties.
  • To explore the link between laterality and reported health problems in a large cohort.

Main Methods:

  • Utilized questionnaire data from a substantial sample of 3829 males and 3631 females.

  • Analyzed self-reported data on hand preference (right-handed, non-right-handed), eye preference, and learning difficulties.
  • Examined reported prevalence of specific health conditions, including cardiovascular disease, ulcers, and diabetes.

    • Main Results:

    • Males reported higher incidences of cardiovascular disease, ulcers, and diabetes compared to females.
    • Increased learning problems were observed in males, non-right-handed individuals, and those with a left eye preference.
    • The highest rates of reading difficulties were found in males who were non-right-handed and right-eyed; non-right-handers with left eye preference also showed elevated rates.

    Conclusions:

    • Self-reported laterality, particularly non-right-handedness and left eye preference, is associated with increased learning difficulties.
    • Specific health conditions show a higher prevalence in males and non-right-handers.
    • These findings highlight the complex interplay between neurodevelopmental factors (laterality) and health/learning outcomes.
