Chronic Disease Indicators

Chronic Disease Indicators logo

The 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-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. More

Notice to users:

2023 Release Live!
The 2023 release (published on January 30, 2023) includes the latest available CDI estimates.

No BRFSS-related estimates for Florida are available for 2021. Florida was unable to collect data over enough months to meet the minimum requirements for inclusion in the 2021 annual aggregate data set.

The 2020 estimates for two indicators, “Proportion of older adults aged ≥65 years who are up to date on a core set of clinical preventive services by age and sex” and “Proportion of older adults aged 50-64 years who are up to date on a core set of clinical preventive services,” were recalculated for women, to correct a coding error.

2020 Behavioral Risk Factor Surveillance System (BRFSS) Data
The BRFSS 2020 colorectal cancer screening questions changed to include five test types (FIT, sigmoidoscopy, colonoscopy, FIT-DNA, and CT colonography) compared to three types (FIT, sigmoidoscopy, and colonoscopy) included previously. Estimates of people getting colorectal cancer screening are higher than in previous years. For more information, visit: Use of Colorectal Cancer Screening Tests | CDC.

Please consider differences in data collection [PDF – 168KB] and potential impacts of the COVID-19 pandemic when comparing 2020 BRFSS estimates with other years.

National Survey of Children’s Health (NSCH) Data
Beginning with the 2016 survey year, the NSCH was redesigned. Because this redesign included changes in how the survey was administered and in what questions were asked, from 2016 on, NSCH estimates of dental visits and preventive dental visits for children and adolescents aged 1–17 years are not comparable to estimates from prior years.
