Childhood Obesity And Precocious Puberty

Decent Essays

The rising problem concerning many parents today is a phenomenon known as precocious puberty, in which the appearance of physical and hormonal signs of puberty occur earlier than normal. Girls at the age of eight and boys at the age of nine or younger who undergo the first stages of puberty are considered abnormal. Although, precocious puberty occurs primarily in girls researchers are finding that it can happen in boys as well. The causes of precocious puberty are still being explored and the science is definitive, yet researchers have found that this early onset of puberty is connected to chemical exposures in the environment, obesity, brain injuries or other growths, and even socioeconomic factors.
Recent studies have shown that the beginning …show more content…

Childhood obesity has become a huge epidemic in many countries. Although, weight-gain is common when going through puberty, abnormally overweight children are in jeopardy of undergoing precocious puberty. The excess fat in obese children can lead to a multitude of medical problems, including disturbing various aspects of puberty. Researchers believe that obesity can alter reproductive hormones, promoting early puberty. “The girls who are obese are clearly maturing earlier,” said Dr. Frank Biro, a pediatrics professor at Cincinnati Children’s Hospital Medical Center. “BMI is, we found, the biggest single factor for the onset of puberty”(Biro). Obesity may be associated with the premature activation of Gonadotropin-releasing hormone (GnRH) and advanced reductions of sex hormone binding globulin (SHBG). Both of these hormones play a significant role in the timing and onset of puberty. The particular chemicals and pollutants being found in breast milk, placenta, womb, and umbilical cord blood are compounds that are fat-loving. These toxins are attracted to fat tissue and tend to accumulate in breast tissue. This suggests that obese girls are undergoing precocious puberty because they are more susceptible to the chemicals from the environment that ultimately alter hormone levels and the timing of …show more content…

The family environment in which a child is growing up in is crucial. Researchers are examining aspects of a child’s family life that could disrupt the timing of puberty, like the relationship of that child with their mother or father. Studies have shown that the absence of a father or male adult figure will result in early puberty (Ellis and Garber 2000). Only a small number of cases of precocious puberty are caused by brain growths and injuries. The brain essentially starts the process of puberty by secreting the hormone GnRH, the pituitary gland in the brain then releases more hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The ovaries then produce estrogen, which stimulates the growth of breasts. Brain injuries and other growths can result in imbalances and disruptions of these hormones’ levels, causing the onset of early
