On April 22, China pediatrics learns to release special investigation result of development that the children of new China grow up the most. Chinese development 9.2 year old on average in age adolescence in girl, than advance 3.3 year old 30 years ago. Chinese pediatrics learn endocrine and hereditary metabolic disease study the intersection of group and the intersection of the whole country and vice the intersection of group leader and Du MinLian Professor, say, girl's development in adolescence is advanced, prove the potentiality of modern's growth is fully expressed.
Division of endocrinology five of BJ Union Hospital studies Professor Yan to tell " life Times " reporter, influenced by multiple factor in adolescence, the bone is a key age. This can be compared to deposit and buy house, the bone is saved to certain extent age, will send out the instruction " the down payment has been deposited enough " to the brain ,Developing at this moment will begin. The modern has great and abundant nutrition, will be much faster than before that the bone increases age, perhaps can save in two or three years ahead of time " The down payment " . And at present, the bone age index of development of adolescence which we base on, or the standard fifty or sixty years ago, so simple development time is advanced, will not be having obvious danger physiologically, it is still a normal phenomenon.
At present, our country to boy the intersection of development and age have the newest statistics adolescence. But military to study the intersection of Yan and Professor, introduce, one investigation of him reveal of our country development time of boy advance to some extent too at present, "in the past, age of average development was 12 years old, it was almost 11 years old now.

But some parents are anxious, child's development is early, the president is not high. Wu XueYan thinks, development is too early, very unfavorable to obtaining ideal height in the future. ", just like the long-jump, the longer the time of run-up is, the farther the distance from starting point to terminal is development. Generally, the boy will grow tall 27 centimetres - 28 centimetres in youthful puberty, it is about 25 centimetres that the girl will grow tall. If development must not grow high finally too early. And the appearing psychological unblance easily. "
Cause the reason to develop too early to be numerous, detergent, pesticide and plastic products substantially as frequently exposed to some and including the estrogen,etc., may all cause the abnormal development of genitals and skeleton. "If parents find obviously accelerating, health has early-maturing inclination in child's growth, should go to the pediatrics of the hospital or division of endocrinology to check as soon as possible, make a few sexual precosity infants caused by serious potential disease diagnosed in time and treated. " Wu Xue Yan emphasizes.
