Serum cholesterol and triglyceride measurements in Canadian physicians
Canadian Medical Association Journal
|February 22, 1975
Summary
This study found elevated serum cholesterol and triglyceride levels in Canadian male physicians, with prevalence increasing with age. Many participants had high lipid values, indicating a need for further cardiovascular health research.
Area of Science:
- Cardiovascular Health
- Clinical Chemistry
- Epidemiology
Background:
- Serum lipid concentrations are critical indicators of cardiovascular health.
- Previous studies have shown varying lipid levels across different populations.
- Understanding lipid profiles in specific professional groups is important for public health.
Purpose of the Study:
- To determine the serum cholesterol and triglyceride concentrations in a cohort of Canadian male physicians.
- To investigate the relationship between age and lipid levels in this population.
- To compare these findings with other national and international studies.
Main Methods:
- Blood samples were collected from 2071 male physicians attending Canadian medical meetings between 1968 and 1973.
- Standardized laboratory analysis was performed to measure serum cholesterol and triglyceride levels.
- Data were excluded if signs of non-fasting were detected (e.g., chylomicronemia, hyperglycemia).
Main Results:
- The mean serum cholesterol was 233.9 mg/dl and mean serum triglyceride was 150.5 mg/dl.
- Elevated lipid values (cholesterol ≥250 mg/dl, triglyceride ≥150 mg/dl) were observed in 34.7% for cholesterol and 36.2% for triglycerides.
- Prevalence of elevated lipid values showed a correlation with increasing age.
Conclusions:
- Canadian male physicians in this study exhibited a high prevalence of elevated serum cholesterol and triglyceride levels.
- These findings suggest potential cardiovascular risks within this demographic.
- The results highlight the importance of considering age-related lipid changes in clinical practice and public health initiatives.

Lipid-Lowering Drugs: Statins and Miscellaneous Agents
Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...
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,...
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.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

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...

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...
