The CDC's chronic disease indicators (CDI) are a set of surveillance indicators developed by consensus among CDC, the Council of State and Territorial Epidemiologists (CSTE), and the National Association of Chronic Disease Directors (NACDD). CDI enables public health professionals and policymakers to retrieve uniformly defined state and selected metropolitan-level data for chronic diseases and risk factors that have a substantial impact on public health. These indicators are essential for surveillance, prioritization, and evaluation of public health interventions. CDI is the only integrated source for comprehensive access to a wide range of indicators for the surveillance of chronic diseases, conditions, and risk factors at the state level and for selected large metropolitan areas.
