Females were recruited during the first trimester of pregnancy between July 2004 and July 2006. Information about parental characteristics and breastfeeding was obtained through questionnaires. Full breastfeeding was categorized as never, short term (≤4mo), long term (4–6mo), or very long term (>6mo).

Maternal social class, education level, and IQ were also associated with child neuropsychological scores, but did not explain breastfeeding associations.
