It looks like the age of puberty onset is decreasing across the globe. I think Peat had mentioned that the puberty is induced by stressors in the organism.
"Although cases of precocious puberty may be few and far between—according to the Mayo Clinic, fewer than 200,000 cases in the United States per year—American girls are hitting puberty younger and younger.
“The age of puberty, especially female puberty, has been decreasing in western cultures for decades now,” Chapa said. “For example, at the turn of the 20th century, the average age for an American girl to get her period was 16 or 17. Today, that number has decreased to 12 or 13 years.”
It’s not just girls, a study from the American Academy of Pediatrics found that boys were starting puberty earlier than previously recorded. According to the findings, boys are now beginning puberty around, or a little before age 10. Previously, 11 years of age was the given number where boys began puberty. The study claimed that the public health implication of these findings is unknown and requires further studies."
“Early puberty in girls has been associated with increased risk of breast cancer, ovarian cancer, obesity and even diabetes in adult life,” Chapa said. “Some of these conditions are related to prolonged and early exposure to estrogen from the active ovarian cycle.”
There are mental health risks to early female puberty as well, especially for a girl going through a big change before her friends.
“Early female puberty has been associated with future psychosocial complications like depression and substance abuse,” Chapa said. “This has been theorized to be a result of neurodevelopmental changes of hormones, such as dopamine and serotonin, caused by puberty, which can lead to risk taking behavior, or simply maladaptation to early onset of secondary sexual characteristics when peers are less physically developed.”"
