概括
儿童肥胖与儿童肝脏脂肪增加有关. 超声波衍生脂肪分数 (UDFF) 与BMI z-score呈正相关性,表明超重儿童的肝脂肪含量较高.
科学领域:
- 儿科胃肠病学 儿科胃肠病学
- 肝病学 肝病学是一种肝病学.
- 医疗成像医学成像
背景情况:
- 儿童肥胖是一个日益严重的全球健康问题.
- 与代谢功能障碍相关的脂肪性肝病是儿童最常见的肝病.
- 超声波衍生脂肪分数 (UDFF) 提供了一种非侵入性方法来量化肝脏脂肪.
研究的目的:

Obesity
1.1K
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...
