The authors examined newborn anomaly scores for 193 normal infants in relation to obstetrical history, newborn dopamine-beta-hydroxylase (DBH), and 5-month (N=185) and 1-year (N=123) infant behavior, determined by a questionnaire completed by their mothers. There was no significant relationship between anomaly score and obstetrical history or 5-month infant temperament; low significant correlations were found between newborn DBH and 1) infant irritability and unsociable response and 2) 1-year anomaly scores and reported activity levels. The authors discuss the possible importance of these findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
