概括
长期暴露于颗粒物 (PM10) 和二氧化硫 (SO2) 空气污染会增加内脏脂肪并减少皮下脂肪,特别是在肥胖男性中. 这些发现凸显了空气污染的严重性.
科学领域:
- 环境健康 环境健康
- 代谢健康 代谢健康
- 流行病学 流行病学
背景情况:
- 长期暴露于空气污染与肥胖有关.
- 对内脏脂肪组织 (VAT) 和皮下脂肪组织 (SAT) 分布的具体影响尚不清楚.
- 本研究研究了空气污染对腹部脂肪指标及其分布的影响.
研究的目的:

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...

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.

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...
