Cincinnati, Ohio 45214


This prospective cohort study examines the role of prenatal and early postnatal lead exposure on the neuropsychological status and social adjustment of adolescents enrolled in the Cincinnati Lead Study. We are examining the relationship between moderate exposure to lead and neuropsychological deficits, difficulties in peer relationships, personality disturbances and juvenile delinquency. This birth cohort of approximately 300 subjects has been followed since 1980 with regularly scheduled assessments of blood lead concentrations, health history, social and hereditary factors, and neurobehavioral development.


Subjects for the Cincinnati Lead Study were recruited prenatally if their mothers resided in areas within Cincinnati, Ohio where there has historically been a high incidence of lead poisoning. Infants were eligible for follow-up if they were greater than 1500 grams at birth and had no disqualifying medical conditions such as defined genetic syndromes or other serious complications that may adversely affect neurobehavioral development.
