儿童和青少年时期，是人体骨骼发育的 "黄金窗口期"。在这段岁月里，骨骼不仅不断生长拉长，骨量也在快速累积，大约在 30 岁左右达到一生中的峰值骨量。峰值骨量越高，相当于给骨骼存下了越丰厚的 "本金"，未来抵御骨量流失、预防骨质疏松的能力就越强。可以说，少年时代的骨骼投资，受益终身。
Childhood and adolescence are the "golden window" of human bone development. During this period, bones not only continuously grow and lengthen, but bone mass also accumulates rapidly, reaching its lifetime peak around age 30. The higher the peak bone mass, the more "principal" saved for the bones, and the stronger the future ability to resist bone loss and prevent osteoporosis. In a sense, bone investment made in youth brings lifelong benefits.
骨骼的发育离不开充足的营养。其中，钙是构建骨骼的核心原料，蛋白质则是骨骼基质的 "钢筋骨架"，而维生素 D 负责促进肠道对钙的吸收，三者缺一不可。青少年每天的钙需求量比成年人更高，建议通过牛奶、奶制品、豆制品、深绿色蔬菜等食物充分摄入。若长期挑食、节食或营养不均，很容易造成钙和蛋白质缺乏，直接拖累骨骼生长。
Bone development cannot do without adequate nutrition. Among nutrients, calcium is the core raw material for building bones, protein serves as the "steel framework" of the bone matrix, and vitamin D promotes intestinal calcium absorption — all three are indispensable. Teenagers' daily calcium requirements are higher than those of adults, and it is recommended to take in sufficient amounts through milk, dairy products, soy products, dark green vegetables and other foods. If one is a long-term picky eater, on a diet or nutritionally imbalanced, calcium and protein deficiency can easily occur, directly dragging down bone growth.
运动同样是儿童青少年骨骼发育的重要推动力。跳跃、跑步、篮球、跳绳等负重运动，能在骨骼生长过程中施加良性力学刺激，促进骨量沉积，帮助积攒更高的峰值骨量。户外运动还能让皮肤接受阳光照射，自然合成维生素 D。研究表明，青少年时期坚持规律运动的人，成年后的骨密度往往更高。久坐、沉迷屏幕、缺乏户外活动，则会让骨骼 "营养不良"。
Exercise is also an important driver of bone development in children and adolescents. Weight-bearing activities such as jumping, running, basketball and jump rope provide beneficial mechanical stimulation during bone growth, promoting bone mass deposition and helping accumulate higher peak bone mass. Outdoor exercise also lets the skin receive sunlight and naturally synthesize vitamin D. Studies show that those who exercise regularly during adolescence tend to have higher bone density in adulthood. A sedentary lifestyle, excessive screen time and lack of outdoor activity, by contrast, leave bones "malnourished".
此外，充足的睡眠对骨骼发育同样关键。生长激素主要于夜间深睡眠时段大量分泌，直接促进骨骼生长与修复。长期熬夜、睡眠不足的青少年，身高和骨骼发育都可能受到影响。因此，规律作息、保证充足睡眠，是少年强骨不可忽视的一环。与此同时，也要避免含糖饮料、碳酸饮料的过量摄入，它们会干扰钙质吸收，对发育中的骨骼不利。
In addition, adequate sleep is also crucial for bone development. Growth hormone is mainly secreted in large amounts during deep sleep at night, directly promoting bone growth and repair. Teenagers who stay up late or lack sleep over the long term may see their height and bone development affected. Therefore, a regular schedule and sufficient sleep are an indispensable part of building strong bones in youth. At the same time, one should avoid excessive intake of sugary and carbonated drinks, which interfere with calcium absorption and are detrimental to developing bones.
儿童青少年骨骼发育的成果，很大程度上决定了成年后的骨骼健康基线。家长应引导孩子均衡饮食、规律运动、充足睡眠、多晒太阳，从小养成科学养骨的好习惯。需要特别提醒的是，儿童的骨骼检查与用药必须在专业医生指导下进行，切勿盲目补钙或随意服用保健品。
The outcome of bone development in children and adolescents largely determines the baseline of bone health in adulthood. Parents should guide children toward a balanced diet, regular exercise, sufficient sleep and more sun exposure, cultivating good bone-care habits from an early age. It is especially worth noting that bone examinations and medication for children must be conducted under the guidance of professional doctors, and one should never blindly supplement calcium or casually take health products.
抓住生长发育的关键期，用营养、运动与睡眠为孩子的骨骼打好根基，就是为他一生的骨骼健康储备最宝贵的财富。从今天起，陪孩子多跑一跑、晒晒太阳，让强健的骨骼陪伴他们一路成长。
Seize the critical period of growth and development, and build a solid foundation for children's bones through nutrition, exercise and sleep — this is to store the most precious wealth for a lifetime of bone health. Starting today, run more with your children and enjoy the sunshine, so that strong bones may accompany them all the way as they grow.
