Should we be worried about early puberty?

Hi to everyone! Today I will comment on an article in the online newspaper "The Guardian", the article is named "Should we be worried about aerly puberty?" (http://www.guardian.co.uk/lifeandstyle/2010/oct/19/worried-about-early-puberty).
The article starts talking about a girl, Hannah, who recently turned 8 years old, and his mother feel shocked because she already shows signs of being in puberty (such as the development of the nipples) ecnuentra which she very early, compared to their situation, unlike what has her daughter, she did not show signs of puberty at an early age.
Along with this case, the paper presents other situations in which demonstrates the acceleration of the onset of puberty in children, especially girls the women, where their first menstrual period, which usually occurs long before now than it was in times past. This is evidenced by speaking of figures, since the author mentions that the average age at onset of puberty is 10.75 years in girls and 11.5 years for males (the first sign for children is the enlargement of the testicles).
Within it an important factor mentioned by the author is currently a tendency to obesity and overweight, which advances the age of puberty, in part because the hormonal changes that start are triggered by the body of a children reach a certain size. "It is very likely that there is a link with the body weight increases, but the data is just beginning to show that," says Hindmarsh. "It makes sense, though. In an era of abundance, a species that always has a great interest in self-preservation tends to reproduce quickly."
Other factors mentioned in the article, are the ratio of the advancement of puberty with the "lack of parental presence, since, according to studies, this situation acts as a signal to the brain of pre-teen girls, triggering the hormonal changes that allow it to reproduce.

The increase in female sex hormones come at a time when your brain is not ready. Children at this age usually are in a stage of childhood where they are in the fantasy game, and changes in the brain that are activated at puberty are all about reality and understand that actions have consequences in the long term . This situation becomes very confusing for young children and as the author relates to the tendency to withdraw and other personality disorders that are directly related to how children cope with this new, accelerated phase, which involves many changes, as it moves from being just a child, to live the series of events and changes which means the transition to puberty.

To end the article talks about recent studies that link early puberty to a greater risk of breast cancer, ovarian cancer and heart disease in adulthood. This situation is certainly alarming to us because it increases the rate of those diseases and predisposes to many people because of the advancement of this vital process to be "ill adults".
