Children evidencing moderately increased lead burden (n = 40) were compared to children not evidencing increased lead burden (n = 48) on three measures of hyperactivity. All children were screened at a local county health department because of suspected lead exposure or as part of the Early and Periodic Screening, Diagnosis, and Treatment program. The three measures of activity were the Routh-Schroeder-O'Tuama free-field measure of gross motor activity, the Conners Parent Rating Scale, and the Werry-Weiss-Peters Activity Scale, both of the latter completed by the parents. As in previous research, a consistent age effect in gross motor activity was found. No difference was found between the groups in gross motor activity or in parental report of activity level. The results suggest that using three of the most widely used measures of hyperactivity, moderate lead exposure does not result in overactivity in preschool-aged children.
