Girls puberty sooner due to obesity

Girls often develop earlier than boys. Girls puberty in about average age from 8 to 12. Usually, babies have to take nearly 3 years to stabilize the process of puberty, but there are also people who just take 2 years, there is need to 6 years to stabilise this process.

Puberty of children increasingly early.

The signs of puberty

With girls, there are two main development signs in "the Tannner" (the term used after a doctor Pediatrics Tanner of his first research on puberty), which is developing breasts and pubic hair development.

Other signs such as the jumpy about height, weight, and the menstrual cycle can also important but is not the measure of the essence when it comes to control the age of puberty.

Increasingly early puberty in girls

The United States recently announced the results of a study conducted on 1200 baby girls. This study focused on the development of the breast tissue, the menstrual cycle. According to which the average age of menstrual cycles remained quite stable and there is no significant change in puberty than before.

However, research by Dr. Marcia Herman-Giddens showed that in the year 1860, puberty on average at the age of 16.6 from females. By 1920, that number is 14.6, 1950 is 13.1; in 1980, that number dropped to 12.5 and in 2010, the average puberty in girls only 10.5.

The study also noted a big difference in the minority. On average, African American girls begin breast development from when 8 years 10 months, this figure in white girls and in Asia is 9 years 8 months, while development in the age of the girls in Spain is from 9 years 4 months of age.

The difference is that significant evidence that we know very little information about the trends around the world.

The causes of early puberty

Ongoing research indicates the relationship between puberty and the BMI (Body Mass Index, used to measure degrees of overweight or obesity of per person).

The other influence factors may be related to a child's development environment. That's the stress, climate, light cycles and exposure to chemical substances. All have certain linkages research would not give exactly the degree of their influence to puberty in girls.=
