Exploring the relation between prenatal and neonatal complications and later autistic-Like features in a representative community sample of twins
Ronald, Angelica and Happé, F. and Dworzynski, K. and Bolton, P. and Plomin, R. (2010) Exploring the relation between prenatal and neonatal complications and later autistic-Like features in a representative community sample of twins. Child Development 81 (1), pp. 166-182. ISSN 0009-3920.
Prenatal and neonatal events were reported by parents of 13,690 eighteen-month-old twins enrolled in the Twins Early Development Study, a representative community sample born in England and Wales. At ages 7–8, parents and teachers completed questionnaires on social and nonsocial autistic-like features and parents completed the Childhood Asperger Syndrome Test. Correlations between prenatal and neonatal events and autistic-like features were weak, both in the whole sample (r = .00–.07) and at the 5% quantitative extreme (phenotypic group correlations = .01–.11), after controlling for socioeconomic status and cognitive ability. Neonatal problems showed modest heritability (13%–14%) and significant shared and nonshared environmental influences (55%–59% and 28%–31%, respectively). Differences in identical twins' neonatal problems correlated weakly with their difference scores on autistic-like features (r = .01–.06).
