Relationship between left-handedness and allergic symptomatology.
Handedness and health parameters were assessed in 70 infants. Video recordings were employed for handedness analysis. The infants' growth and health were periodically followed up from birth and information was retrieved from medical records. A significant association between left-handedness and allergy score was found (P < .05). Age (P < .02) and sex (P < .01) appear to be significant covariates. It appears that the possible association between left-handedness and immune-based diseases among adults applies to infants as well. A possible biologic marker for allergy should be incorporated in future research.
