[quote=Anonymous]The last time this came up on DCUM, I looked at the scientific research on this. Here's what I found. -- The median age at which American girls get their period is 12 and a 1/2. It is about 12 for African-American girls. -- That has not really changed in recent history (it was much older in pre-industrial history, when nutritional and exercise patterns were very different). -- Less than 10% of girls get their period before age 10, and more than 90% of girls get it before age 15. -- Signs of puberty can begin a year or two before age of first menstruation. -- That HAS changed in recent history -- girls in recent years are showing signs of puberty earlier than they did in our generation, our parents generation, our grandparents generation. The best guess is that this is due to all the chemicals in the environment and our food, although the fact that we are generally larger also is thought to play some role.[/quote]
