アルコールと血脂. 協力型リポプロテインフェノタイプ化研究
Lancet (London, England)
|July 23, 1977
まとめ
この研究は,アルコール摂取が血中脂質レベルと関連していることを明らかにしています. アルコール摂取量の増加は,高密度の脂質タンパク質コレステロールとトリグリセリドの増加,低密度の脂質タンパク質コレステロールの減少と相関する.
科学分野:
- 心血管の健康についてです.
- 脂質代謝についてです.
- 栄養学的流行病学について
背景:
- 血中脂質レベルは,心臓血管の健康の重要な指標です.
- アルコール摂取などのライフスタイル要因が脂質に与える影響を理解することは,公衆衛生にとって不可欠です.
- 以前の研究では,アルコールと脂質プロフィールとの関連が示唆されていますが,多様な集団にわたる包括的なデータが必要です.
研究 の 目的:
- アルコールの摂取量と血液中の主要な脂質レベル (HDL,LDL,トリグリセリド) の関連性を調査する.
- これらの関連性を5つの異なる研究集団で調べる.
- アルコールの脂質への影響が用量依存であるかどうかを判断する.
主な方法:
- 5つの大規模な人口調査のデータを分析した:アルバニー,エヴァンス郡,フレーミングハム,ホノルル,サンフランシスコ.
- 報告されたアルコール摂取量と測定された血脂レベルとの関係を評価するための統計的相関分析.
- アルコール消費の異なる範囲における脂質レベルにおける段階的な応答の検討.
主要な成果:
- アルコール摂取と高密度脂質タンパク質 (HDL) コレステロールの間の一貫した正の関連性は,すべての集団で確認された (r = 0.160.30).
- 脂質レベルの変化は,低消費レベルでも,アルコールの摂取に対する段階的な反応であるように見えた.
- アルコール摂取量と低密度脂質タンパク質 (LDL) コレステロールの間で否定的な相関が観察されました.
- アルコール摂取とプラズマトリグリセリドの間で,控えめな正の相関が見られた.
結論:
- 報告されたアルコール摂取は,血液の脂質プロファイルと強く関連しています.
- 適度なアルコール摂取は,HDLコレステロールレベルに有益な影響を与える可能性があります.
- これらの発見が心血管疾患リスクに及ぼす臨床的影響を理解するために,さらなる研究が必要である.

Lipid Digestion
Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.
Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Lipid-derived Compounds in the Human Body
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...

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...
Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
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...
