Total and high-density lipoprotein cholesterol in adults: National Health and Nutrition Examination Survey, 2011-2012.

High levels of total cholesterol and low levels of high-density lipoprotein (HDL) cholesterol (the "good cholesterol") are risk factors for coronary heart disease (1–5). To identify persons who may be at risk for developing coronary heart disease, adults are advised to have their cholesterol checked at least once every 5 years (i.e., to be screened for cholesterol) (6). A previous study reported declining trends in the percentage of adults with high total cholesterol during 1999–2010 (7). This report presents estimates of the percentages of adults aged 20 and over with high total cholesterol, low HDL cholesterol, and screened for cholesterol, based on data from 2011–2012, and compares them with corresponding estimates from 2009–2010. Analysis is based on measured cholesterol only and does not take into account whether lipid-lowering medications were taken.
