与健康的同龄人相比,患有青少年异常性关节炎 (JIA) 的青少年的骨矿物质密度和含量较低. 在JIA患者中,较低的体力活动与这些骨差异无关,但活动仍然对整体健康至关重要.
科学领域:
- 儿科风湿病学 儿科风湿病学
- 骨健康和新陈代谢
- 青少年健康 青少年健康
背景情况:
- 青少年异常性关节炎 (JIA) 与青少年的体力活动减少有关,与典型的发展同龄人相比.
- 较低的体力活动可能会对骨发育和健康产生负面影响.
- 这项研究研究了患有和没有JIA的青少年的骨矿物质含量 (BMC) 和区域骨矿物质密度 (aBMD).
研究的目的:
- 为了比较JIA和对照的青少年之间的全身BMC和aBMD.
- 检查JIA青少年中适度至强度体力活动 (MVPA),瘦身量和骨结果之间的关联.
主要方法:
- 21名患有JIA的青少年和21名年龄和性别匹配的对照组 (10-20岁) 参加.
- 评估包括身高,体重,跳跃距离,加速计测量的MVPA,以及BMC,aBMD和瘦肉质的双X射线吸收计.
- 用多个线性混合效应模型分析了高度调整的z-score.
主要成果:
- 与对照组相比,患有JIA的青少年表现出明显较低的aBMD (p=0.03) 和BMC (p=0.04) z分数.
- 患有JIA的青少年每天减少了22分钟的MVPA,但MVPA与aBMD或BMC没有显著联系.
- 瘦身量与aBMD (p=0.03) 和BMC (p<0.001) 两者都有积极的关联.
结论:
- 与对照人群相比,患有JIA的青少年表现出全身aBMD和BMC的减少.
- 观察到的骨差异并不能通过JIA组中较低的MVPA水平来解释.
- 尽管有这些发现,但促进体育活动对于青少年的福祉仍然很重要.

Bone Disorders
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...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Changes in the Appendicular Skeleton with Age
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...
