2nd November, 2012: A recent study has suggested that the onrush of puberty dropped by over 5 years in girls. The researchers also believe that junk food is certainly to be blamed for that. Experts only say that nowadays some girls, who are just 6 or 7 years of age, have to deal with their first period. The study, conducted in the United States, also saw that boys are also reaching their physical maturity around 2 years earlier.
Scientists claimed that girls’ average age for the onrush of puberty was 16.6 years in 1860; and by 1920 it came down to 14.6 years. By 2010, it came down to 10.5 years on average.
Puberty is actually a body changes’ process from adolescence to full adult development. The process is brought about by some chemical signals that are sent to pituitary gland from the brain and then the pituitary sends it to the sex glands – testicles in boys and ovaries in girls. Now, researchers fear that this early transition may lead girls to get pregnant at an early age.
The new research was conducted at the University of North Carolina. Scientists also claimed that obesity can be blamed for this early transition as it alter body hormones and some starts to show first signs of maturity as early as at the age of 6. For Hispanic and white boys, the average age is 10 whereas it is 9 for black boys.
