Young Girls Developing Breasts By Age 7 or 8

The question that the media fail to adequately address, even though they love these headlines, is why? My guess is that it must be environmental — something in the food, water or air that our children are exposed to. Other ideas? Report from the LA Times:

Doctors and parents were stunned when research published more than a decade ago found American girls were beginning puberty at much younger ages, some as early as 7. A new study released Sunday suggests the average age at which puberty begins may still be falling for white and Latina girls.

According to the paper, which appears in the journal Pediatrics, almost 25% of African American girls have reached a stage of breast development marking the onset of puberty by age 7, as had almost 15% of Latina girls and more than 10% of white girls.

Those percentages are significantly higher than in 1997, when a landmark study first reported that girls were beginning puberty much younger than they had in the mid-20th century. In that study, the rate of girls who had begun puberty at age 7 was, on average, 5% for whites, compared with 10.4% in the new study.

In other words, the average age of puberty onset still appears to be in flux.

“In 1997, people said, ‘That can’t be right; there must be something wrong with the study,’ ” said Dr. Frank M. Biro, director of adolescent medicine at Cincinnati Children’s Hospital Medical Center and the lead author of the new study. “But the average age is going down even further.”

Biro’s study included 1,238 girls ages 6 to 8 who lived in one of three regions: Cincinnati, East Harlem, N.Y., or San Francisco. Puberty was determined by two examiners who worked independently to assess the girls’ breast development. By age 8, 27% of the girls had begun puberty: 18.3% of whites, 42.9% of blacks and 30.9% of Latinas…

    “The question that the media fail to adequately address, even though they love these headlines, is why?”

    You just blew your credibility, because the LA Times story explores the “why” question specifically, starting in paragraph eight. Obesity and high-fat diets are amongst the causes.

    • Did you notice the word “adequately” in the quoted sentence?

      While we're happy that you visit our site so regularly and that you are an avid commenter, it's hard not to notice your constant criticism of the stories posted here. One does start to wonder why you keep coming back for more. Perhaps you might be happier at a site such as, for example only, Newsmax.

      Alternatively, if you would like to start submitting your own stories to the site please feel free to do so. You may not have realized that the majority of stories posted on the site are in fact from users of the site, not our editorial team, hence the frequent clash of ideas on the site.

      Thank you.

      • Submitting a story and having it published would weaken his identity as a Righteous White Male Businessman victimized by the absolutely and universally stupid and evil Left. Taking such initiative and personal responsibility would match his rhetoric, but the results would contradict his hypocritical worldview. The falsehood of his laissez-faire religion, upon which his psyche believes it depends, is slowly being revealed and he's desperate. He's in a war; his “truth” versus the facts. Note that almost without exception, everything he says about leftists, foreigners, racial minorities, and women is true of himself. It's psychological projection.

        In short, this is Disinformation, and that's exactly what he's here to spread.

          No, he's a troll. I wouldn't be surprised if he's actually a socialist activist, but in reality, he's probably an obese 40 year old man with jizz stained underwear. ALL of his underwear. But yeah, it's the shit we put in the food making the kids fat and introducing estrogens before the body produces them on their own. Yay free market!

    • There are numerous potential explanations for why puberty is starting earlier. Chief among them is the increase in average body weight among children over the last three decades, Lee said. Excess body weight, especially body fat, is thought to increase the blood levels of estrogens that promote breast development. Earlier studies, including one by Lee, have linked early puberty to higher body mass index as far back as the toddler years.

      But other studies suggest that body fat may not be the only cause. A Danish study released last year in the journal Pediatrics found puberty occurring earlier in children regardless of body mass index at age 7. Factors may include a diet that is increasingly high in sugar and fat, declining physical activity and exposure to endocrine disrupters, chemicals in the environment that act on hormones.

      “Kids today are exposed to plastic much more than they were 10 or 20 years ago,” Lee said.

      The answer to why is still open to debate. If you're ever tired of looking like a short bus resident in public you could do some homework or just shut the hell up.

    Ah yes, latino and white…the two whoriest races….makes perfect sense…

    Clearly obesity and high fat diets play somewhat of a role…. though additionally animal growth hormones in the food these children eat as well as genetically modified plants play a more key factor here. GMO soy causes early maturation in females because of the isoflavones in soy mimic estrogen. Also, it causes feminization in young males… which is clearly demonstrated within the emo music scene.

  4. This exact same situation occured in Peru around 15 years ago. The culprit? Too many hormones were being pumped into the fish and chicken int Peru, both of these were staple foods in an average Peruvian's diet.

    interestingly, studies have shown that girls who have been sexually abused in childhood often have an early onset of puberty. this would suggest that psychological events can trigger physical development. could we perhaps consider that bratz dolls, playboy pencil cases, push-up bra and g-string sets for pre-teens and other such examples of the premature sexualisation of young girls in our society these days may have something to do with this? just a thought…

    • My thinking exactly…although I'm not ready to espouse it as more than as thoughts, and from there as part of the picture.

      One way to test the hypothesis, though: we'd need to find a place where girls WEREN'T being prematurely sexualized. If at those places the girls were hitting puberty at fourteen or fifteen, then we'd be onto something. Just don't suggest Yemen, as they seem to have a thing for seven-year olds.

    China has them starting even younger:

    In their case they traced it directly back to a brand of milk powder.

  7. Ffs it's bisphenol-A. They don't spray it on the inside of food and beverage tins just for fucking chuckles. Case closed.

  8. Earlier puberty hm? Does this mean more 7 year olds who swear they're 18 to get into clubs? Should we lower the age of consent? Or, being very irreverent, is this a new biological form of self defense against pedophiles (they don't like em developed)?

  9. makes me want to cry seriously this is not a good thing…its their diet
