    • The bar graph view shows estimates from a single survey cycle at a time.
    • The table view shows all estimates numerically.
  • Different topics include chronic conditions, diet, infectious disease, and oral health.
  • Filters differ for each dashboard based on data availability and content relevance.

Download the data set in CSV format choosing from the center drop-down menu.

* Because of changes in sample design and oversampling strategies, data are available for non-Hispanic Asian people for 2011–2012 onward and for Hispanic people for 2007–2008 onward. Before 2007–2008, Mexican-American people were oversampled. The Hispanic category includes Mexican-American people.

Estimates for people reporting more than one race are not shown separately, because statistically reliable rates are difficult to make for this group. But these estimates are included in the total.

Chronic Conditions

Pregnant persons were excluded from analyses involving obesity and hypertension.

Data for hypertension and high total cholesterol are only shown for adults aged 20 and over.

Diet

Estimates are based on one dietary recall interview and are not adjusted for energy intake.

Intakes of nutrients and other dietary components are based on the consumption of food and beverages, including water, and do not include intake from supplements or medications. Breast-fed children were excluded.

† Estimates for vitamin D intake are only available for 2007–2008 onward.

Infectious Disease

Data for herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) were not collected for people aged 50 years and over.

Oral Health

§ Estimates for dental caries in permanent and primary teeth are not available for 2005–2006 through 2009–2010 when tooth decay was only assessed in all teeth present at the time of examination, not just in permanent or primary teeth alone.

Definitions

Chronic Conditions

Hypertension: Systolic blood pressure greater than or equal to 130 mmHg, diastolic blood pressure greater than or equal to 80 mmHg, or currently taking medication to lower high blood pressure.

High total cholesterol: Serum total cholesterol greater than or equal to 240 mg/dL.

Obesity among adults: Body mass index (BMI, weight in kilograms divided by height in meters squared) greater than or equal to 30.

Obesity among children and adolescents: BMI (weight in kilograms divided by height in meters squared) greater than or equal to the age- and sex-specific 95th percentile of the 2000 CDC growth charts.

Infectious Disease

Herpes simplex virus type 1 (HSV-1): Antibody to herpes simplex virus type 1 from tested sera.

Herpes simplex virus type 2 (HSV-2): Antibody to herpes simplex virus type 2 from tested sera.

Oral Health

Total dental caries: Treated and untreated tooth decay (dental cavity) in primary or permanent teeth.

Untreated dental caries: Tooth decay (dental cavity) in primary or permanent teeth that has not received appropriate treatment.

Complete tooth loss: The loss of all natural, permanent teeth.

Data Source and Methods

Data from NHANES were used for these analyses. NHANES is a cross-sectional survey designed to monitor the health and nutritional status of the U.S. civilian noninstitutionalized population. The survey consists of interviews conducted in participants’ homes and standardized physical examinations, including a blood draw, conducted in mobile examination centers.

Filters differ for each topic based on data availability and content relevance.
