title: Multiple birth-risk factors and handedness in elementary school children.
abstract: The relationships between a set of birth-risk factors, i.e., sex, parity, and maternal age, and handedness were computed for 600 elementary school children. None of these birth-risk variables (or relevant combinations of them) were significantly related to handedness. These data further question the validity of the hypothesis that left-handedness results from stressful prenatal and birth conditions.
