early puberty

A new study published in the journal Lancet Child & Adolescent Health shows that puberty, marriage, parenthood ... of teenagers have changed dramatically in recent years.

Recent research by scientists shows that over the past 100 years, human changes have been evident in height, weight, puberty and longevity.

When a child enters puberty sooner than expected, doctors often cannot explain why. However, researchers have discovered a gene mutation that causes some early puberty cases.

At puberty for 1 year early, children will be at risk of some 6% higher cancers than their normal peers.
