性早熟的儿童，进入青春期后身高将比同龄伙伴矮约10~15厘米。近年来儿童性早熟现象越来越普遍，年龄也越来越提前。
专家认为，导致儿童“性早熟”的原因除了视听产品中“儿童不宜”的情爱镜头，以及整个社会的“泛情爱化”资讯外，就是不当的喂养方式。有10种食物，是目前比较公认的可能会造成儿童性早熟的食物，有些食物很常见，但很少引起家长的重视！下面让我们来看看上了催熟黑名单的“危险”食物。
【10大催熟食品】
值得一提的是，这些食品并不是吃一次就会引起性早熟，而是一个日积月累的过程。以防万一才是最明智的选择，毕竟关乎到孩子的一生。
NO.1 自制豆浆
自家磨的豆浆非常浓郁，其中含有较多大豆黄体酮。虽没有认定它能直接导致性早熟。但长期食用，可能会诱发孩子发育问题。
NO.2 鱼子蟹黄
鱼子蟹黄，都是水生物排出的卵子，虽然美味，但不宜给孩子多吃，存在使孩子发育变快的危险。
NO.3 蜂王浆
蜂王浆是公认不该给孩子多吃的食物，除了含有激素容易导致性早熟外，还容易让孩子上火积热，对身体很不好，妈妈们别给孩子吃。
NO.4 反季节蔬菜和水果
冬季的草莓、葡萄、西瓜、西红柿等，春末提前上市的梨、苹果、橙和桃，几乎都是在“促熟剂”的帮助下才反季或提早成熟，一定要避免给幼儿食用。
NO.5 燕窝
燕窝里含有丰富的燕窝酸，给孩子适量地吃燕窝，会促进智力水平的发展。但过量吃，会造成激素水平上升。4个月以上的婴幼儿吃燕窝的量以2—3克/天为宜。
NO.6 榴莲
榴莲含有的热量及糖分较高，熟透还可能包含酒精成分，孩子吃了不好，营养过剩导致发育异常。
NO.7 鸡鸭颈
禽肉中的“促熟剂”残余主要集中在家禽头颈部分的腺体中，而鸡翅、鸭颈、鹅颈等恰是十分受儿童欢迎的流行食品。
NO.8 过多肉类
蛋白质是孩子发育所必须的，但吃过多，会造成孩子体内营养过剩或脂肪堆积，进而引发内分泌紊乱，导致性早熟。
NO.9 把果汁当水喝
果汁和饮料口感好，很多孩子每天都缠着要喝。某些妈妈就把果汁当水给孩子喝。殊不知这样会让孩子提早发育，对肠胃也会造成严重损害。
NO.10 药膳药补
现在很多家庭养生观念很强，药膳在餐桌上很常见，但小孩不宜食用，药膳中的药材如：枸杞、党参等药物，均不适合小孩子食用。
小贴士
在日常生活中，家长应时刻关注孩子的成长，利用给孩子洗澡、穿衣等机会，仔细观察孩子的身体状况。
一旦发现女孩在8岁前出现明显的或进行性的乳房发育，10岁前来例假；或者男孩在9岁前出现声音、体毛、外生殖器的变化等性早熟的征兆，须立即到医院检查。
只要治疗及时，大多数性早熟孩子症状都有能得到明显改善，并逐步恢复正常。妈妈们不用太担心，平时注意孩子的饮食，让孩子多运动就可以了。

如何判断性早熟
　　性早熟是一种以性成熟提前出现为特征的性发育异常,即为在正常性发育年龄以前出现乳房发育,阴毛、腋毛出现,身高、体重迅速增长,外生殖器发育等第二性征。女孩在8岁以前、男孩在9~10岁以前出现第二性征的发育,都属于性早熟的范畴。

\n

性早熟
　　性早熟在临床上大体分为中枢性早熟与外周性早熟。中枢性早熟亦称真性性早熟,真性性早熟的幼儿下丘脑―垂体―性腺轴的调节功能会过早发育,少数有家族史。外周性早熟又称假性性早熟,仅有部分性征的发育提前,而无性功能的成熟。与真性性早熟的本质区别是无下丘脑―垂体―性腺轴的真正启动,即性腺大小与儿童年龄相符,只是第二性征提前发育。

到目前为止,最为严重的就是假性性早熟现象,表现为单个性器官发育,例如女孩子乳房发育,男孩子开始长胡须、长喉结等。

　　1、造成心理障碍

　　孩子生理一旦早熟，看到自己与周围人不同的性状特征时极易引起孩子自卑。这种心理，很可能在其成年后都留有遗症。

　　2、影响学习

　　性征的出现和生殖器官的发育过早出现，孩子肯定会分心、不安、害羞和紧张。同时，女孩身体发育过早，没有能力处理好月经，不仅给生活带来不便，还会影响学习。

　　3、影响身高

　　由于性激素的提前催发，骨骺闭合也将大大提前，生长期相应变短，影响身高。

　　4、致使孩内分泌失调

　　早熟会导致孩子内分泌失调，出现全身性多毛、减少、干枯，甚至脱落等情况。

　　5、产生社会问题

　　性早熟会使孩子过早具有生育能力，由于自制力不足，心智不成熟等原因，容易使小孩早恋，甚至产生如小女生怀孕、小男生性犯罪等社会问题。

1、个儿长不高。由于骨骼发育过快，性早熟儿童的生长周期会明显缩短，没有足够时间发育，最终使其成年后的身高比一般人矮，未治患者最终身高可能为1.55至1.60米。

　　2、肿瘤征兆。一少部分性早熟儿童的病因可能是因颅内肿瘤压迫所致，如果得不到及时处理，将会危及患者生命。

　　3、性行为提前。性早熟儿童的心理发育与身体发育极不匹配，加上患者生理年龄小、社会阅历浅、自控能力差，容易导致其性行为提前，从而引发怀孕和性疾病传播的危险。

　　4、性格压抑。性早熟的孩子可能因为自己在体形、外表上与周围小伙伴不同，过早地背起沉重的思想包袱，产生自卑、恐惧和不安情绪，对日后的心理健康产生长久的不良影响。

　　5、埋藏社会隐患。性早熟的孩子身体发育很快，他们更向往模仿社会上的一些东西，比如性爱和暴力。他们也因此比一般孩子更容易发生“危险”，比如早恋，甚至产生堕胎、性犯罪和自杀等社会问题。

$\"女孩性早熟的5个检查项目\"$

女孩性早熟应该是很常见的现象了，女孩出现了这样的情况对家庭的影响是很大的，大家对女孩性早熟的特征应该多一些了解，发现了这样的特征及时的去治疗才能够尽早的治愈，减少影响。

　　一、发育信息观察

　　8 岁以前，乳房是否发育、腋毛生长情况、外阴有无发育、阴毛是否出现、阴唇是否着色（颜色变深）、阴道分泌物增多、不满10岁的女孩月经来潮。10岁以前孩子身高突然增长加速也是性早熟的一个信号。正常女孩在8岁以后可以出现乳房发育。乳房有一个从小到大的发育过程，可以一侧开始出现，也可以两侧同时出现，这些都不属于异常现象;当发现女儿10周岁后月经来潮，也不必紧张，这属于正常范围。

　　二、体检信息包括：

　　1.一般检查：包括身高、体重、乳房、腋毛、外生殖器检查。

　　2.B超检查：B超是诊断性早熟的常规检查方法之一，可以发现乳房发育情况，鉴别乳房炎症或肿瘤;子宫及卵巢的发育情况，有无内生殖器官的疾病等;另外，也可发现与性早熟有关的肾上腺肿瘤。

　　3.妇科激素水平检测：女童性早熟是少女科常见的内分泌病，根据激素水平高低可推测性早熟的原因或病变部位。

　　4.测骨龄：在性早熟中，骨龄指标非常重要，X线测骨龄比实际年龄提前2年以上为骨龄提前，假性性早熟骨龄与年龄相符，而真性性早熟约95%的患儿骨龄提前。

　　5.必要的时候，还可做头颅CT或核磁共振检查，以便排除颅内肿瘤。

　　女孩性早熟的特征大家应该知道了吧，这些特征都是很明显的，也是对孩子很有影响的，特别是女孩的特征就会更明显了，乳房过早的发育了，如果家长能够尽早的发现，尽早的去治疗，很多的患者都能够得到很好的治疗的。

　　1、动植物中残留的激素

动物饲料添加剂中含有激素，被饲养的动物体内就有激素残留，这样制成的肉制品被孩子吃掉后，也会对儿童的身体发生作用。另外，反季节蔬菜和水果大部分都是激素催成的，常吃这样的水果对孩子的身体也不好。

　　2、环境类激素作祟

　　洗涤剂、农药及塑料工业向环境排放的物质及其分解产物可在自然界产生一系列类激素污染物，这些污染物如被儿童摄入，即可引起生殖器官及骨骼的发育异常。

　　3、盲目进补

　　这种原因引起的儿童性早熟在南方城市体现得较为突出。这是因为很多人在煲汤时将动物内脏一起煲，其中动物的性腺等内分泌腺体含有激素物质，通过进餐可进入人体。

　　4、保健品摄入

　　有些家长盲目给不爱吃饭的孩子服用可以增强食欲的保健品，但一般能够增加食欲的保健品常常含有激素成分，长期服用可引起儿童血液中激素水平上升，进而导致性早熟。

　　5、过早的心理刺激

　　从统计资料看，较闭塞地区比开放地区的性早熟患者要少得多，农村患儿明显少于城市患儿，农村女孩较城市女孩月经初潮年龄明显滞后，这些都是心理因素起作用的明证。

　　6、受某些疾病的影响

　　受一些疾病（如颅内肿瘤、遗传等因素）的影响，儿童也会出现性早熟。因此，家长们要注意观察儿童的发育情况，一旦发现孩子过早出现第二性征，应该及时到内分泌科检查诊治，以免病情发展。

外周性性早熟会不会转变为中枢性性早熟?

外周性性早熟会转变为中枢性性早熟，也就是说，假性性早熟可转变为真性性早熟。其机制是，外周性性早熟患儿，由于摄入外源性的性激素或内源性的性激素合成、分泌增加，体内性激素水平的增高，一方面可作用于骨骼，使其成熟加速；另一方面性激素还可直接作用于中枢而激发下丘脑-垂体-性腺轴的活动。

近年来的研究发现，在促性腺激素释放激素基因内存在经典的雌激素应答成分，外周性激素水平，如雌激素持久增高，可刺激促性腺激素释放激素的合成、分泌增加，从而诱发真性性早熟。在临床上这些患儿发病初期表现为外周性性早熟，但当骨龄突增时，则转变为中枢性性早熟。
