Study: More girls entering puberty earlier

[JTsyo]

actually i think he is right. i seem to recall reading that . Since girls (and boys) are gaining more fat it fools the body into thinking its ready for children and the onset of puberty starts.

Though i also read a study that said girls are hitting puberty faster because they don't have a father figure in there life.

And the best is the hormone's and such in milk and meat are causeing girls to hit puberty faster.

either way whats for sure are girls are developing younger. not just obese but even the skinny girls are. i don't remember girls looking like they do now.

Wouldn't that have been easy for the study to find? They could just compare the BMI of the ones that hit puberty early to the average.

It's natures way of telling them their bodies are ready for sex. Who can argue with that?

Maybe you should do some basic research then on body fat and pregnancy.

I believe his point was that the person was doing nothing to back up what they said and was probably just making their best guess

He didn't just pull it out of his ass:

Timing of normal pubertal maturation has received increased attention over the past several years. Age of menarche showed a dramatic decrease in the first half of the 20th century in Western nations; since 1960, the decrease in age of menarche has slowed and, in some societies, has actually increased. More recently, age of onset of pubertal maturation appears to have decreased, especially in girls. Multiple studies have demonstrated that childhood levels of obesity and ponderosity are associated with earlier menarche in girls. Earlier maturation in boys, however, is associated with lower adiposity and ponderosity. Secular changes in the United States as well as around the world have noted increases in prevalence as well as extent of overweight. Factors contributing to these changes include increases in calories and fast food consumption, decreases in physical activity, and increases in television viewing. There appear to have been selective advantages to lower metabolic rate (the 'thrifty' gene hypothesis), and earlier maturation. However, changes in caloric consumption, caloric density and physical activity, combined with greater lifespan, may allow expression of the adverse consequences of these adaptations, such as the metabolic syndrome or cancers.

Yes, it was exactly that.

Since it was phrased as "I definitely think" rather than "having read certain studies (link), I've come to believe this or that", it sounded as if he was posting a personal theory.

Thanks for allowing me to clarify.
