| Abstract |
Despite reductions of the amount of lead in various sources over the past few decades, elevated blood-lead concentrations in children continue to be a public health concern. Using data from three environmental lead studies the Comprehensive Abatement Performance (CAP) Study, the Baltimore Repair and Maintenance (R&M) study, and the Rochester Lead-In-Dust study, the relationships among environmental lead levels and children's blood lead concentrations were examined using structural equation models (SEM). SEM was used for this analysis because the method accounts for the covariance among variables that allow direct and, in particular, indirect effects of various sources of lead to be assessed. Traditional multiple regression only assesses the direct effects. The primary analysis of this report focused on two types of structural equation models: environmental-lead pathway models and blood-lead pathway models. The environmental-lead pathway models were structured to assess the direct and indirect impact of several environmental variables such as soil lead, window sill dust-lead, and window well dust-lead on floor dust-lead so that comparisons could be made across the three studies (CAP, R&M, and Rochester). |
