In a study conducted by Dr. Herbert L. Needleman, a psychiatrist at the University of Pittsburgh Medical Center, and published in The Journal of the American Medical Association (JAMA), a startling discovery has been made. Boys with relatively high levels of lead in their bones were more likely to engage in aggressive acts and delinquent behavior than boys with less lead in their bones. The study looked at 800 boys, from public schools in Pittsburgh, PA, for four years. These children were not suffering from lead poisoning and other factors such as maternal intelligence, socioeconomic status, number of children in the family, the presence of two parents in the home, the children's race and their medical history were also considered in this study. The lead was collected from the children's leg bones and compared with their level of aggressiveness as reported by parents, teachers and the children themselves. It must be stated clearly that the study does not say that lead exposure is the only cause of aggressiveness and delinquent behavior, but this information can be used as a prevention tool. Lead levels in the bones had its own independent effect on aggressiveness and delinquency, separate from intelligence. Lead is a brain poison that interferes with the ability to restrain impulses. Given that a child is exposed to lead, it increases the chances of expressing this aggressive behavior.
