儿童的生长可分为三个阶段,即所谓婴儿期—儿童期—青春期的生长模式。婴儿期是宫内生长的继续,表现为出生后的短时期生长加快,主要依赖于营养和血清中营养性生长素。儿童期开始于生后第二年的某一时期,生长再次加快,此后身高的增长趋于稳定并逐渐减缓,本期几乎完全依赖于生长激素(GH)。青春期的到来,使生长速度再次加快,这一期依赖于性激素和GH。 儿童的正常生长速度是判断所有生长障碍的依据,生长比例的高低将影响儿童的最 Children’s growth can be divided into three stages, the so-called infancy - childhood - adolescent growth pattern. Infancy is the continuation of intrauterine growth, manifested as short-term growth after birth to accelerate, mainly dependent on nutrition and serum auxin. Childhood begins at a certain period of the second year after birth, and growth accelerates again. Since then, height growth has stabilized and gradually slowed down. This issue is almost entirely dependent on growth hormone (GH). The advent of adolescence, so that the growth rate to accelerate again, this period depends on sex hormones and GH. The normal growth rate of children is the basis for judging all the growth disorders, the level of growth will affect the child’s most
