青春期是由儿童发育到成人的过渡时期,这一时期人体在形态、功能、内分泌及心理行为等方面都发生着巨大的变化。由于青春期伴随着性发育和性成熟,个体之间无论从外形特征、生长速度和成熟度上都存在着明显差异。虽然从流行病学、分子生物学、代谢内分泌学和遗传学等角度不断探索,但迄今为止对青春期的启动、调节和控制机制仍知之甚少。 Adolescence is a period of transition from children to adults. During this period, the human body has undergone tremendous changes in morphology, function, endocrine and psychological behavior. Because adolescent with sexual development and sexual maturity, no matter from the appearance characteristics, growth rate and maturity, there are significant differences. Although the epidemiology, molecular biology, metabolic endocrinology and genetics and other aspects of continuous exploration, but so far adolescent initiation, regulation and control mechanisms are still poorly understood.
