营养不良、大多数显著的蛋白质缺乏,不仅通过减少骨量,而且通过改变肌肉功能来导致骨质疏松性骨折的发生。此外,营养不良与骨质疏松性骨折发病率增加有关。生长调节素系统(IGF-1)可能直接涉及老年人髋部骨质疏松性骨折及其并发症的发病机制。低IGF-1水平是髋骨骨折的危险因素。维生素D和钙摄入量合适的研究对象,给予纠正自然蛋白质摄入量不足的蛋白质补充量可增加循环血中IGF-1,改善髋骨骨折后的临床结局,和预防股骨近端骨矿物质密度的丢失。补充蛋白质也可明显减少住院患者康复治疗的时间。这些资料强调了适量营养素摄入量在骨质疏松性骨折防治方面的重要性。
Malnutrition, most notable protein deficiency, causes osteoporotic fractures not only by reducing bone mass, but also by altering muscle function. In addition, malnutrition is associated with an increased prevalence of osteoporotic fractures. The somatomedin system (IGF-1) may be directly involved in the pathogenesis of hip osteoporotic fracture and its complications in the elderly. Low IGF-1 levels are a risk factor for hip fracture. Vitamin D and Calcium Intake Proper studies of patients with protein supplements that correct deficiencies in natural protein intake may increase circulating blood IGF-1, improve clinical outcome after hip fracture, and prevent proximal femoral bone mineral The loss of density. Supplementary protein can also significantly reduce the time spent on rehabilitation of hospitalized patients. These data highlight the importance of proper nutrient intake in the prevention and treatment of osteoporotic fractures.
