Question 5#

Recent statistics from the American Heart Association (AHA) Statistical Update in 2014 report that all of the following regarding dyslipidemia in the United States are true EXCEPT that:

A. 98,900,000 U.S. adults over 20 years of age have elevated TC >200 mg/dL (43.4%)
B. 35.8% of adults have LDL >130 mg/dL (71 million adults)
C. 48.7 million adults (21.8%) have HDL <40 mg/dL
D. National Health and Nutrition Examination Survey (NHANES) data through 2006 reported that 10.3% of adolescents (12 to 19 years) have abnormal lipid levels
E. inadequate control of dyslipidemia is responsible for 4 million yearly deaths worldwide and 350,000 in the United States

Correct Answer is D

Comment:

National Health and Nutrition Examination Survey (NHANES) data through 2006 reported that 10.3% of adolescents (12 to 19 years) have abnormal lipid levels. In adolescents between the ages of 12 and 19, the number of individuals with one or more abnormal lipid level is higher at 20.3% and increases further to 42.9% in association with obesity. All the other facts noted are true. The AHA has established TC <170 mg/dL in children and <200 mg/dL in adults as one of seven goals for ideal cardiovascular health. In one survey in 2010, 38.1% of children and 52.7% of adults did not meet these criteria. Although average adult TC levels have been dropping over the past two decades from 208 to 197 mg/dL, obesity and lack of physical activity (two factors associated with dyslipidemia and diabetes risk) have been on the rise. From 2011 to 2012 only 20.7% of adults and 49.5% of adolescents, respectively, achieved recommended activity levels. These facts and more can be found in the most recent Heart Disease and Stroke Statistics-2014 Update from the AHA published in Circulation.
