There is a need for systematic approaches to assessment of environmental factors most relevant to health, health outcomes most influenced by the environment, and relationships between them, as well as for approaches to representing results of such assessments in policy deliberations. As a step in the development of such methods, we used findings and data from environmental protection and public health sectors to develop a set of measures representing topics relevant to children’s environmental health. We used a definition of the environment that emphasized contaminants and a process that involved both analytic and deliberative elements. The steps in this process were to: a) develop a conceptual framework to depict relationships between environment and health with relevant types of data and information, b) select topic areas of significance for children, c) identify best available data sources and devise measures, d) assess possible surrogate data sources and measures when needed, e) design and implement metrics for computation of measures; f) select graphical representations of measures, g) identify related measures, and h) identify data gaps. Representatives of policy and stakeholder audiences participated in this process.
