Insights

Cardiovascular disease (CVD) risk definitions vary for women. Both the U.S. Preventive Services Task Force (USPSTF) and American Heart Association (AHA) identified high dyslipidemia prevalence, especially in older women.

Area of Science:

  • Cardiovascular Health
  • Public Health
  • Epidemiology

Background:

  • High cholesterol is a precursor to cardiovascular disease (CVD).
  • Current guidelines recommend cholesterol screening for at-risk women.
  • Varying definitions of CVD risk impact dyslipidemia prevalence estimates in women.

Purpose of the Study:

  • To estimate the proportion of women without a prior dyslipidemia diagnosis who meet U.S. Preventive Services Task Force (USPSTF) and American Heart Association (AHA) cardiovascular disease (CVD) risk criteria.
  • To report dyslipidemia prevalence stratified by age and CVD risk definition.

Main Methods:

  • Utilized 2007-2008 National Health and Nutrition Examination Survey data (n=1,781).
  • Analyzed a representative sample of the U.S. civilian, non-institutionalized population.
  • Estimated proportions of women meeting USPSTF and AHA at-risk criteria and reported dyslipidemia prevalence by age.

Main Results:

  • Over half of younger women (20-44 years) and 74.2% of older women (≥45 years) were USPSTF at-risk.
  • Nearly all women (99.5% younger, 99.6% older) had at least one AHA risk factor.
  • Dyslipidemia prevalence was 47.3% for USPSTF-at-risk younger women and 65.5% for USPSTF-at-risk older women; AHA-at-risk prevalence was 39.5% and 63.3%, respectively.

Conclusions:

  • The AHA risk definition identified more women (45% more younger, 25% more older) than the USPSTF definition.
  • Both definitions identified similar dyslipidemia prevalence estimates among women.
  • High dyslipidemia prevalence in younger women warrants further research on early identification and treatment to reduce future CVD mortality.

Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
