概括
在老年男性中,通过频繁的中断来打破久坐时间,可以显著降低反复跌倒的风险. 这种策略比简单地减少总体久坐时间更有效,以防止跌倒.
科学领域:
- 老年学是指老年学的学科.
- 流行病学 流行病学
- 身体活动研究 身体活动研究
背景情况:
- 久坐不动行为是老年人落和骨折的危险因素.
- 休息久坐生活对跌倒和骨折风险的影响需要进一步调查.
研究的目的:
- 检查老年男性中从久坐生活中休息的频率与经常性跌倒和骨折的活跃发作之间的纵向关联.
主要方法:
- 从男性骨质疏松性骨折研究 (MrOS) 中对2918名男性 (年龄为79.0±5.1年) 进行了长度研究.
- 使用SenseWear腕带收集的活动数据;静坐和运动的发作按持续时间 (≥5分钟) 和强度 (<1.5MET静坐,≥1.5MET活动) 定义.
- 经常性跌倒 (≥2/年) 和骨折分别在4年和8.4年内评估,使用统计模型 (GEE,Cox比例危险).
主要成果:
- 在静止时间的休息和反复跌倒之间发现了显著的非线性U形关系 (p < 0.001).
- 中等频率的静坐休息 (13.6-<20.4) 与较少的休息 (1.4-<13.6) 相比,与较低的反复跌倒几率 (ORs 0.82-0.79) 有关.
- 较高的久坐休息频率与较低的骨折风险有关,尽管经过对总久坐时间的调整后减弱;对活跃发作频率没有关联.
结论:
- 断绝长时间的久坐时间对于降低老年男性的跌倒风险至关重要,这与总久坐时间无关.
- 鼓励经常休息的策略可能有利于老年人群的跌倒预防.
- 在这个队列中,活跃发作频率与跌倒或骨折风险没有显著的关联.

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...

3.2K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
