中新网5月24日电 近日，有家长反映孩子骨密度偏低，担心是否缺钙。对此，专家表示，儿童与成人不同，骨密度低不一定意味着缺钙。
专家指出，骨密度是反映骨骼健康的一个重要指标，它代表了骨骼内钙质沉着的程度。在成人中，骨密度的降低可能与缺钙有关，因为成人骨骼的生长周期已经结束，骨质的增加主要通过矿物质的沉积来实现。然而，对于正在成长发育的儿童来说，骨密度的降低并不一定意味着缺钙。
儿童正处于生长发育的关键时期，他们的骨骼需要不断地生长和重塑。在这个过程中，骨骼的矿物质含量会发生波动，因此，儿童的骨密度测量结果可能会因为生长发育的动态变化而出现不同。如果孩子的骨密度低于正常水平，首先应该考虑的是孩子的整体健康状况，包括营养摄入、生活习惯和遗传因素等。
此外，儿童的骨骼生长速度较快，这意味着他们的骨骼正在积极地形成和重建。这种快速的生长过程可能会导致骨密度暂时性的下降，但这并不代表孩子缺钙。相反，这可能是孩子生长旺盛的标志。
专家建议，家长应该关注孩子的整体营养状况，确保孩子摄入足够的钙质和维生素D，以及适量的户外活动，以促进骨骼健康。如果家长对孩子的骨密度问题感到担忧，应咨询专业的儿科医生或营养师，以获得更专业的建议和指导。
总之，儿童骨密度低不一定意味着缺钙，它可能是孩子生长发育过程中的正常现象。家长应关注孩子的整体健康，并在必要时寻求专业医疗意见。

News Title: “Low Bone Density in Children Does Not Necessarily Indicate Calcium Deficiency: a Marker of Robust Growth”
Keywords: Bone Density, Children’s Growth, Not Calcium Deficiency

[Beijing, May 24th, 2023] – Recently, parents have reported concerns about their children’s low bone density, worrying about whether they are deficient in calcium. In response to this, experts have stated that children are different from adults, and a low bone density does not necessarily mean a calcium deficiency.
Experts pointed out that bone density is an important indicator reflecting bone health, representing the degree of calcium deposition in bones. In adults, a decrease in bone density may be related to calcium deficiency, as the growth cycle of adult bones has ended, and bone mass increase mainly occurs through the deposition of minerals. However, for children who are in the critical period of growth and development, a decrease in bone density does not necessarily mean a calcium deficiency.
Children are in a critical period of growth and development, and their bones need to grow and remodel continuously. During this process, the mineral content of bones can fluctuate, so the results of bone density measurements in children may vary due to the dynamic changes in growth and development. If a child’s bone density is below the normal range, the first thing to consider should be the child’s overall health, including nutritional intake, lifestyle, and genetic factors.
Moreover, the rapid growth rate of children’s bones means that their bones are actively forming and rebuilding. This rapid growth process may lead to a temporary decrease in bone density, but it does not mean that the child is deficient in calcium. On the contrary, this may be a sign of robust growth in children.
Experts suggest that parents should pay attention to their children’s overall nutritional status and ensure that they receive sufficient calcium and vitamin D, as well as adequate outdoor activities to promote bone health. If parents are concerned about their children’s bone density, they should consult pediatricians or nutritionists for more professional advice and guidance.
In summary, a low bone density in children does not necessarily indicate a calcium deficiency, and it may be a normal phenomenon in the process of growth and development. Parents should pay attention to their children’s overall health and seek professional medical advice when necessary.
