Methodology Notes: 

    Total cholesterol is a combination of high-density lipoproteins (HDL), low-density lipoproteins (LDL), and very low-density lipoproteins (VLDL). Total blood cholesterol is measured enzymatically in a series of coupled reactions. A description of the procedures for the total cholesterol measurement in NHANES has been published by NCHS.

    Blood cholesterol levels less than 200 mg/dL are considered desirable. Levels of 240 mg/dL or above are considered high. Levels of 200-239 mg/dL are considered borderline.

    Individuals who take medication to lower their serum cholesterol levels and whose measured total serum cholesterol levels are below the cut-offs for high and borderline high cholesterol, are not defined as having high or borderline high cholesterol, respectively.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2014, the baseline data by obesity status and the confidence intervals were revised due to a change in the methodology. Obesity status was originally coded based on the calculated BMI variable (BMXBMI) and had an error in the 2007-08 dataset. Some records had a missing height or weight but not a missing BMXBMI. To be consistent with NHANES reports, instead of using the calculated BMI variable, BMI is now computed directly from the weight and height variables. In addition, the BMX 2007-2008 updated April 2011 file was used. The method for computing the confidence intervals was revised from the standard Wald method to the Wald method on the log scale.
