- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 跌倒和身体不活动是老龄化人口的重大问题.
- 了解身体活动与不同出生阶段的摔倒之间的关系对于有针对性的干预至关重要.
研究的目的:
- 为了比较两个不同的老年妇女出生队伍之间的身体活动水平和跌倒发病率.
- 在这些群体中,检查身体活动与无伤害和伤害性落之间的关联.
主要方法:
- 利用了澳大利亚妇女健康纵向研究的数据,比较了1921-26年出生和1946-51年出生的女性.

- 采用了千-平方测试和多项逻辑回归来分析队列差异和活动-跌落关联.
主要成果:
- 较晚的出生队列 (1946-51) 与较早的队列 (1921-26,43%) 相比,对推的体育活动水平的坚持更高 (59%).
- 后来的队列报告了更多的非伤害性跌倒 (14%对8%),而伤害性跌倒率相似 (15%对14%).
- 达到每周150-300分钟的体育活动与两个队伍中无伤及伤害性跌倒的几率明显降低.
结论:

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...

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

01:09Changes in the Appendicular Skeleton with Age

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...

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...
