This pilot study investigated adolescents with well-documented childhood lead burdens to
determine the relationship between lead and unintentional injury. Adolescents completed a
self-administered injury questionnaire. Results demonstrated that elevated childhood blood
lead concentrations were significantly related to injury variables. Further study is necessary
to understand adolescent health and safety implications.

study represent an important contribution to the field of pediatric injury prevention, and I
commend the authors on their provocative work. I take issue, however, with the authors'
conclusions, which seem to suggest that the most likely mediator between pediatric lead
exposure and subsequent unintentional injury risk is decreased balance and neuromotor
performance. I would advocate the possibility that high impulsivity might mediate the …
