概括
这项研究表明,老龄化的希腊妇女在腿部经历了显著的骨和肌肉质量损失,手臂的变化不那么明显. 这些发现凸显了随着年龄的增长,身体组成变化的区域差异.
科学领域:
- 老年学是一门学科.
- 人体生理学 人体生理学
- 医疗成像医学成像
背景情况:
- 人口老龄化面临着与年龄相关的疾病带来的越来越多的公共卫生挑战.
- 从双能X射线吸收计 (DXA) 获得的骨和软组织指标与老年人的不良健康结果有关.
研究的目的:
- 用全身DXA扫描来研究健康希腊女性四肢的区域性身体组成.
- 检查尾部位的骨和软组织测量之间的与年龄相关的关系.
主要方法:
- 全身DXA扫描被用来分析20-85岁的330名希腊妇女的腿和手臂的身体组成.
- 计算的指标包括骨矿物质密度 (BMD),瘦质量 (LM) 和脂肪质量 (FM).
主要成果:
- 骨矿物质密度 (BMD) 在腿部 (20-30岁) 和手臂 (41-50岁) 达到峰值.
- 在腿部骨质量 (43%) 和手臂骨质量 (32.2%) 中观察到与年龄相关的显著减少.
- 峰值瘦肉量 (%LM) 发生在腿部和手臂 (20-30岁),与年龄相关的腿部%LM (22.5%) 和手臂%LM (6.6%) 显著下降.
- 在腿部 (年龄31-40岁) 和手臂 (年龄61-70岁) 达到峰值脂肪量 (%FM),与年龄相关的腿部%FM (7.5%) 和手臂%FM (1.9%) 的轻微减少.
- 希腊妇女显示,与年龄的增长相比,腿部%LM和%FM与手臂相比显著减少.
结论:
- 希腊妇女在成年早期达到腿部骨质的峰值,随着年龄的增长,骨质损失主要发生在腿部.
- 在这个人群中,年龄的增长与腿部瘦身和脂肪质量相比,与手臂质量相比,与腿部瘦身和脂肪质量的显著减少有关.
- 了解尾骨和软组织的这些与年龄相关的变化对于未来专注于健康衰老的临床试验至关重要.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:19The Effect of Aging on Tissues
2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
