概括
皮厚度的超声波 (US) 测量,当翻倍估计皮值时,将全身脂肪质量 (FM) 估计高出约5%. 这种方法与四组件模型不一致,应避免用于准确的身体成分分析.
科学领域:
- 身体组成分析分析.
- 营养评估 营养评估
- 诊断成像诊断成像的使用
背景情况:
- 准确的身体成分评估对于营养状况评估至关重要.
- 超声波 (美国) 在营养实践中被用于估计身体成分参数,如脂肪质量 (FM).
- 传统上,FM估计依赖于使用皮厚度测量的预测方程,可以通过美国成像得到.
研究的目的:
- 为了评估使用美国衍生的皮肤折叠测量在人类学方程中估计全身FM的有效性.
- 将美国衍生的FM估计与参考四组件 (4C) 模型进行比较.
- 为了确定美国人体成分分析的准确性和一致性.
主要方法:
- 在37名活跃成年人 (19名男性,18名女性) 中,使用人类学和美国标准测量了皮厚度.
- 美国衍生和人类皮测量被输入到埃文斯方程中,以估计FM.
- 根据一个四组件 (4C) 模型验证了FM估计值.
主要成果:
- 在人类测量方程中使用美国衍生的皮导致FM的高估值高达4.8% (p < 0.01).
- 协议分析显示,美国衍生的FM与4C模型之间的一致性相关系数为0.33.
- 观察到一个积极的趋势 (r = 0.8;p < 0.01),但达成一致的界限在 -3.4%至0.6%之间.
结论:
- 将美国皮厚度测量量进行翻倍,以估计皮值,结果大约高估了FM的5%.
- 这种做法导致在团队和个人层面上对4C模式缺乏共识.
- 建议专门为美国测量开发新的方程,以提高身体组成的准确性和优化营养策略.

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...

Ultrasonography
4.4K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
