Notes

Estimates for high total cholesterol, hypertension, and obesity among adults are age adjusted by the direct method to the U.S. Census 2000 population using age groups 20–39, 40–59, and 60 and over.

Due to 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. Prior to 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 are included in the total.

 

Definitions

Hypertension: Systolic blood pressure greater than or equal to 130 mmHg, or 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 (weight in kilograms divided by height in meters squared) greater than or equal to 30.

Obesity among children and adolescents: Body mass index (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.

 

Data Source and methods
