概括

具有高风险骨应力损伤 (BSI) 的活跃女性表现出较差的骨质健康标志物. 这项研究发现,在高风险的BSI病例中,骨矿物质密度较低,饮食担忧增加,而不是负载率较高.

科学领域:

整形外科整形外科整形外科
运动医学运动医学
骨健康骨健康骨健康

背景情况:

骨压力损伤 (BSI) 是活跃女性中普遍存在的过度使用损伤.
脊髓炎被分为高风险 (骨盆,圣体,大腿部) 或低风险 (大腿骨,长腿骨,四足骨) 的疾病.
关键的风险因素包括低能量的可用性,月经不规则和骨健康受损.

研究的目的:

确定与绝经前妇女BSI相关的因素.
为了比较患有高风险BSI,低风险BSI和没有BSI史的女性.
测试高风险的BSI是否与较低的骨矿物密度 (BMD) 和较差的骨微架构相关,以及低风险的BSI是否与更高的负载率相关.

主要方法:

一项涉及45名绝经前妇女的横截面研究 (每组15名:高风险BSI,低风险BSI,没有BSI).
双能X射线吸收计 (DXA) 测定全身,部和脊椎的BMD (z-分数).
高分辨率的外围定量计算断层扫描 (HR-pQCT) 用于骨微架构;饮食障碍检查问卷 (EDE-Q) 用于饮食行为;仪器化跑步机用于负载率.

主要成果:

与低风险BSI相比,患有高风险BSI的女性的脊柱z分数明显较低 (-1.04vs. -0.01).
高风险的BSI组报告了更高的EDE-Q分数的形状和饮食问题和更大的体重波动.
在高风险BSI组中,更多的女性每晚睡眠时间少于7小时 (80%对33.3%).
在各组之间没有发现垂直负载率的显著差异.

结论:

患有高风险BSI的女性表现出更多的骨健康不良的风险因素,包括较低的BMD.
饮食问题和睡眠障碍在患有高风险BSI的女性中更为普遍.
跑步负载率并没有区分有或没有BSI史的女性.

Bone Disorders

Bone Disorders

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...

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
