America's Children and the Environment (ACE)

ACE Health

The Health indicators present information on children's diseases, conditions, and outcomes that may potentially be influenced by environmental exposures. Many factors contribute to children's health, including genetic inheritance, nutrition, and exercise, among others. The adverse health consequences of some environmental exposures may occur through interactions with these other risk factors, and it is often difficult to determine the extent to which the environment (or any other factor) contributes to children's health outcomes of concern.

The Health section is organized as a series of topics, each topic as a separate page. Each topic is presented separately with Indicator, Background, and Methods navigation tabs. The Indicator tab includes each indicator presented as a figure, followed by a text box describing the characteristics of the data displayed, and bullet points that highlight key data from the indicator. The Background tab includes a discussion of the scope of the issue and a brief snapshot of the relevant scientific literature regarding associations between exposures and health effects. The Methods tab includes a description of the data source and a description of how the indicator is calculated.
