Girls in the U.S. may be continuing to hit puberty at earlier ages, according to new research.
The findings suggest earlier development than what was reported in a 1997 study and show a worrying pattern, say the study's authors, led by Dr. Frank Biro of Cincinnati Children's Hospital Medical Center. Girls who hit puberty earlier are more likely to engage in risky behavior, Biro's team notes, and might be at a higher risk for breast cancer, than their peers who develop later.
"This could represent a real trend," Dr. Joyce Lee, a pediatric endocrinologist at the University of Michigan who was not involved with the new research, told Reuters Health.
Doctors are unsure of what could be causing girls to develop at a younger age, but rising obesity rates may be to blame, they say.

Hormone laden foods (dairy, meat)
Increased levels of body fat? In my day, the heavier, bigger girls tended to be the ones who hit puberty first-

90lbs is the bodies trigger for starting your period. Because in your bodies "mind" that is enough weight to carry a baby. I've read a bunch of studies on this. Environment, food, weight, and family history are what they think that plays a big factor in starting puberty young.

I had read about this. Many studies have linked added hormones to food (beef, milk) to the early onset. There have also been studies that have demonstrated a weight connection. For some reason, I am remembering 105 pounds to be the trigger. This may be the wrong number and only my wishful thinking for a younger me! :) My daughter started menstruating at age 11 and she was at a higher BMI than I was at her age. I was almost in high school when this began. Some of it is genetic--my side of the family is tall and on the thinner side whereas her father's family tends to be shorter and more stocky. It does make one more aware of the things that go into the food we feed our families.
