Does Mother's IQ Explain the Association Between Birth Weight and Cognitive Ability in Childhood? Intelligence 33,5 (September-October 2005): 445-454. Also: http://www.sciencedirect.com/science/article/pii/S0160289605000577 Cohort(s): Children of the NLSY79, NLSY79 Publisher: Elsevier Keyword(s): Armed Forces Qualifications Test (AFQT); Birthweight; Cognitive Ability; I.Q.; Peabody Individual Achievement Test (PIAT- Math); Peabody Individual Achievement Test (PIAT- Reading); Peabody Picture Vocabulary Test (PPVT); Test Scores/Test theory/IRT There is a significant association between birth weight and cognitive test scores in childhood, even among individuals born at term and with normal birth weight. The association is not explained by the child's social background. Here we examine whether mother's cognitive ability accounts for the birth weight–cognitive ability association. We analysed mother and child data from the National Longitudinal Survey of Youth 1979. Random effects models were employed to utilise fully the repeated cognitive tests on the same child, and to include all children of each mother. Mother's score on the Armed Forces Qualification Test (AFQT) was significantly related to child's birth weight. Birth weight was significantly related to the child's scores on the Peabody Individual Achievement Test. This association was attenuated by up to two-thirds after taking into account mother's AFQT score. In this large sample the association between birth weight and cognitive ability was substantially explained by mother's IQ. [ABSTRACT FROM AUTHOR; Copyright 2005 Elsevier] |
