Overview

For 2009–2010, 21.3% of adults aged 20 and over had low HDL cholesterol (less than 40 mg/dL) in the United States. The percentage of adults with low HDL cholesterol was higher for men (31.4%) than for women (11.9%). Percentages among men were also higher than those among women of the same racial and ethnic group. For men, the percentage with low HDL cholesterol was lower among non-Hispanic black men than non-Hispanic white or Hispanic men. No racial or ethnic differences were found among women in the percentage with low HDL cholesterol.^[1]

Low HDL Epidemiology and Demographics

Prevalence

In 2009–2010, 21.3% of adults aged 20 years and over had low HDL cholesterol level (less than 40 mg/dL) in the United States.

In Europe, the prevalence of low HDL-cholesterol was estimated to be approximately 33% among men and 40% among women, with very low HDL-cholesterol present in 14% (both genders combined). A higher prevalence was reported among diabetic patients compared to the general population.^[2]

Gender

During 2009–2010, approximately 31% of men and 12% of women had low levels of HDL cholesterol. Percentages among men were also higher than those among women of the same racial and ethnic group.^[3]

Shown below are diagrams depicting the prevalence of low HDL cholesterol by age group and sex in the United States between 2009 and 2010 (Source:CDC.gov).

In Europe, the prevalence of low HDL-cholesterol was estimated to be approximately 33% among men and 40% among women.^[4]

Race

For men, the prevalence of low HDL cholesterol was lower among non-Hispanic black men than non-Hispanic white or Hispanic men.^[3]

No racial or ethnic differences were reported among women with low HDL cholesterol.^[3]

Shown below is a diagram depicting the prevalence of low HDL cholesterol by ethinicity in the United States between 2009 and 2010 (Source:CDC.gov).

Age

The percentage of adults with low HDL cholesterol declines with age for men and women.

 ==Overview==
-Epidemiological studies have shown that high concentrations of HDL (over 60 mg/dL) have protective value against [[cardiovascular disease]]s such as ischemic [[stroke]] and [[myocardial infarction]]. Low concentrations of HDL (below 40 mg/dL for men, below 50 mg/dL for women) are a positive risk factor for these atherosclerotic diseases.

The percentage of adults with low HDL cholesterol was higher for men (31.4%) than for women (11.9%). Percentages among men were also higher than those among women of the same racial and ethnic group.

-Data from the landmark [[Framingham Heart Study]] showed that for a given level of LDL, the risk of heart disease increases 10-fold as the HDL varies from high to low. Conversely, for a fixed level of HDL, the risk increases 3-fold as LDL varies from low to high.
