概括
升高的残留胆固醇 (RC) 与美国成年人的内脏脂肪组织 (VAT) 和肥胖风险增加有关. 这种联系在心血管疾病患者中尤为明显,需要进一步调查因果关系.
科学领域:
- 心血管健康 心血管健康
- 代谢综合征是代谢综合征的一种.
- 脂质代谢 脂质代谢是什么
背景情况:
- 内脏脂肪组织 (VAT) 积累是代谢功能障碍和心血管风险的关键指标.
- 剩余胆固醇 (RC) 是一个新兴的脂质标记物,但它与内脏肥胖的关联需要进一步阐明.
- 了解RC和VAT之间的关系对于识别具有更高健康不良结果风险的个体至关重要.
研究的目的:
- 在一个代表性的美国成年人群中调查残留胆固醇 (RC) 水平和内脏脂肪组织 (VAT) 之间的关联.
- 确定RC是否是内脏肥胖的一个独立预测因素.
- 探索RC的预测性能与内脏肥胖的其他脂质标记物相比.
主要方法:
- 从国家健康和营养检查调查 (NHANES) 中对5301名美国成年人的横截面分析.
- 其余胆固醇 (RC) 计算为总胆固醇 - HDL-c - LDL-c.
- 通过双能X射线吸收计测量内脏脂肪组织 (VAT);内脏肥胖症定义为VAT面积≥100cm2.
主要成果:
- 内脏肥胖的患病率显著增加,RC的四分位数较高 (16.51%至74.48%,p<0.001).
- 调整后的分析显示,RC水平与内脏肥胖风险之间存在正相关性 (OR=1.039,p<0.001).
- 与参考组相比,具有特定RC/LDL-c配置文件的个体表现出明显更高的内脏肥胖风险.
结论:
- 升高的残留胆固醇 (RC) 水平与内脏脂肪组织 (VAT) 的增加和内脏肥胖的更高风险显著相关.
- 与其他脂质标记物相比,RC显示出对内脏肥胖的优异预测能力.
- 在RC和内脏肥胖之间的因果关系需要进一步的研究,特别是在特定的子组,如那些心血管疾病.

Cholesterol: Significance and Regulation
524
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 III: Serum Lipid Profile
143
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...

Lipids: Dietary Sources and Requirements
715
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...

Hypodermis
4.3K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

Obesity
418
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
