Cara Natterson: 近年来,儿童青春期提前已成为一个令人担忧的现象。其原因可能包括压力、抗生素暴露以及内分泌干扰物的影响。压力会导致身体产生皮质醇,从而影响青春期的启动。抗生素的广泛使用,特别是动物饲养中抗生素的使用,可能导致肠道和卵巢炎症,从而影响青春期发育。最近的研究表明,一种名为麝香酮的常见环境化学物质,存在于许多化妆品和日用品中,与青春期提前有关。麝香酮进入人体后,会影响下丘脑释放促性腺激素释放激素(GnRH),进而影响垂体释放促黄体生成素(LH)和促卵泡素(FSH),最终引发青春期变化。虽然目前尚无明确的结论,但这些因素很可能共同作用,导致青春期提前。作为医生,我呼吁大家关注日常生活中可能接触到的内分泌干扰物,并尽量减少接触。同时,我们也需要关注儿童的心理健康,减轻他们的压力,创造一个健康成长的环境。 Vanessa Kroll-Bennett: 青春期提前并非全是坏事,但它确实会带来一些风险。研究表明,青春期提前的女孩更容易出现物质滥用、焦虑、抑郁、较低的自我形象以及更早的性行为等问题。然而,这些关联并不意味着因果关系。关键在于,当孩子看起来比实际年龄大时,社会会以更成熟的眼光看待他们,这可能会增加他们面临风险的可能性。因此,我们需要重新思考我们对青春期的传统观念和语言,避免给孩子带来不必要的压力。我们应该庆祝孩子在这个阶段的成长和变化,理解他们是一个不断发展变化的过程。青春期教育应该是一个持续的过程,从幼儿时期就开始,教会孩子正确的身体部位名称,以及尊重自己和他人的身体。随着孩子年龄的增长,我们可以逐步深入地与他们讨论身体变化、自我保护以及性关系等话题。重要的是,要根据孩子的年龄和心理发展水平,选择合适的方式进行沟通。 Isaiah King: 我记得我11或12岁时,我的声音开始变化。我感觉自己经历了很大的变化,变得更成熟了,但在某些方面,我还是个孩子。青春期是一个持续变化的过程,我的身体和大脑都在不断发展。

Chapters
Research indicates puberty onset is happening earlier in children, potentially due to factors like stress, antibiotic exposure, and endocrine-disrupting chemicals (EDCs) like musk ambret found in cosmetics and fragrances.
  • Puberty onset is happening earlier for both boys and girls compared to data prior to the 1990s.
  • Stress, antibiotic exposure, and EDCs are potential factors contributing to early puberty.
  • A chemical called musk ambret, found in many fragrances, has been linked to earlier puberty onset.
  • Fragrance ingredients are often not listed on product labels, making it difficult for consumers to identify EDCs.
