Statistics and Tracking
CDC's National Center for Chronic Disease Prevention and Health Promotion
engages in surveillance activities in order to:
- Collect data to better understand the extent of health risk
behaviors, preventive care practices and the burden of chronic diseases
- Monitor the progress of prevention efforts
- Help public health professionals and policymakers make more timely
and effective decisions
The Center’s surveillance activities provide data and statistics relevant
to each of its program (link to “Programs” page) areas. Listed below are
links to CDC’s major chronic disease surveillance systems.
CDC’s Major Chronic Disease Surveillance Systems
Behavioral Risk Factor Surveillance
The BRFSS is a state-based system of health surveys that make up the world’s
largest telephone survey. The survey tracks health risks in the United
States and uses this information to improve the health of the American
people. Available resources include the following:
- Prevalence Data:
State-level estimates can be compared to other states and grouped by
Data: Observe state-level trends in the prevalence of certain health
- SMART Data:
View local area estimates and statewide “Quick View” charts.
- BRFSS Maps:
Generate maps displaying state- and local-level estimates.
Annual Survey Data: Download the data and documentation for all
completed survey years.
BRFSS Questionnaires page: View questionnaires for the BRFSS survey
in English and Spanish versions.
WEAT: Web Enabled Analysis Tool: It includes the following advanced
- Cross Tabulation Analysis - Create Cross Tabulation Reports from the
BRFSS data for Analysis.
- Logistic Analysis - Analyze the BRFSS data using Logistic
Chronic Disease Indicators
Chronic Disease Indicators (CDI) is a cross-cutting set of 90 indicators
that were developed by consensus and that allows states and territories to
uniformly define, collect, and report chronic disease data.
Health-Related Quality of
The concept of health-related quality of life refers to a person or group's
perceived physical and mental health over time. The purpose of HRQOL
surveillance is to identify unmet population health needs; recognize trends,
disparities, and determinants of health in the population; and inform
decision making and program evaluation in the area of public health.
National Assisted Reproductive
Technology Surveillance System (NASS)
To fulfill the mandate of the Fertility Clinic Success Rates and
Certification Act of 1992, CDC maintains a surveillance system designed to
collect information on Assistive Reproductive Technology (ART) treatment
outcomes from all infertility clinics in the United States, and publishes an
annual report. Data collected includes patient profile, reasons for ART
treatment, type of ART procedure, treatment outcomes, and clinic contact
Diabetes Surveillance System
The National Diabetes Surveillance System provides resources documenting the
public health burden of diabetes and its complications in the United States.
National Health Interview
The National Health Interview Survey (NHIS) is a large-scale household
interview survey. Survey results are instrumental in providing data to track
health status, health care access, and progress toward achieving national
National Health and
Nutrition Examination Survey (NHANES)
The National Health and Nutrition Examination Survey (NHANES) is designed to
assess the health and nutritional status of adults and children in the
United States. The survey is unique in that it combines interviews and
National Oral Health Surveillance
NOHSS presents data from state-based and national surveys to monitor trends
in key indicators of oral health status, oral health care utilization,
receipt of preventive interventions such as water fluoridation and dental
sealants, and state oral health program infrastructure.
National Program of
NPCR funds population-based cancer registries in 45 states, the District of
Columbia, Puerto Rico, and the U.S. Pacific Island jurisdictions to collect
data on the occurrence of cancer; the type, extent, and location of the
cancer; and the type of initial treatment. These data enable public health
professionals to better understand and address the cancer burden.
National Youth Tobacco Survey
NYTS is a nationally representative cross-sectional school-based survey of
public school students enrolled in grades 6-12. NYTS provides the data
needed to inform the development, implementation, and evaluation of state
and national comprehensive tobacco control programs that work to prevent
young people from initiating tobacco use and help those who have already
started using tobacco to quit.
Pediatric and Pregnancy Nutrition
The Pediatric (PedNSS) and Pregnancy Nutrition Surveillance System (PNSS)
Web-based training site provides online training modules and uses case
studies to show how to read a table, review data quality, interpret the
data, use the data for program evaluation, and disseminate the data in
reports and facts sheets.
Pregnancy Risk Assessment Monitoring
PRAMS collects state-specific, population-based data on maternal attitudes
and experiences before, during, and shortly after pregnancy.
State Tobacco Activities
Tracking and Evaluation (STATE) System
The State Tobacco Activities Tracking and Evaluation (STATE) System is an
electronic data warehouse containing up-to-date and historical state-level
data on tobacco use prevention and control. The STATE System is designed to
integrate many data sources to provide comprehensive summary data and
facilitate research and consistent data interpretation. STATE System
presently offers the ability to generate reports for the following topic
areas: Behaviors, Demographics, Economics, Environment, Funding, Health
Consequences and Costs, and Legislation. The STATE System is the primary
data source for tobacco control legislation on Advertising, Excise Tax,
Licensure, Preemption, Smokefree Indoor Air, and Licensure. These data are
collected and analyzed by the STATE System.
Behavior Surveillance System
The YRBSS was developed to monitor priority health risk behaviors that
contribute markedly to the leading causes of death, disability, and social
problems among youth and adults in the United States.
