Early adulthood… is it dangerous?
some studies suggest that obesity may be the reason behind early puberty
In Peru live child, "Lina Medina" It was born in 1933. He was five years old and seven months when she gave birth to her first child and no one knows who the father is. And when she was about eight months you started menstruation for the first time, at the age of four years appeared Nhadaha and became her above the pubic hair.
The medical tests showed that she underwent a five years old, she's a woman full of physical terms. In 1939 her baby was born by Caesarean section, and he weighed 2.7 kg. Her son grew up and he thinks it's a big sister, until he was ten years old. He lived true until he was forty years old, and died ill Bone Marrow. What happened?
In the middle of the eighteenth century, European girl reaches puberty, sexual and happen to have a menstrual for the first time when an average of seventeen, while it is happening today when it reaches the third years of age. Even breasts became appear at an early age. In the last fifteen years became chest begins to emerge, on average, the earliest full year, ie before they reach the girl ten years of age. The figures appeared in Danish search was in 2009. And despite the fact that sexual maturity for male children is not at the same speed, but the data also indicate that they have become aged earlier than previously.
In a study in 2007 on 463 were born in the city of "Copenhagen" Swedish showed that they reached sexual maturity before four months earlier than usual. In another study took place in Bulgaria in 2010 showed that the boys reached maturity sooner full year, compared with another study that took place thirty years ago.
Researchers have measured the length of the testes in 6200 Born between the ages of 0 and 19 years old, and found that it begins as big at the age of nine, which is the first signal to start the process of puberty and into adolescence with children who participated in a similar study in 1980 began to increase in the length of testes occur at the age of thirteen.
Adult body and mind children
This early sexual transmission, which has been documented in children brought concern for the professionals, because this transition does not comply with the physical speed of mental and social maturation similar. This can carries problems when the child and the girl child needs to change the pattern of their behavior to conform to the social controls that are governed by different rules than the rules of childhood is still a child mentally.
And various research has shown that whenever the girl reached sexual maturity earlier the greater the likelihood
of disease, depression and psychological conflict has. And in both sexes, in the event of early puberty, increases their likelihood learning smoking and harmful habits or criminal activities, or start having sex early or having to sexual deviation in the case of gender segregation.
In addition to the implications of the results are harmful to health when they reach puberty early. In a Norwegian study from the University of "Bergen and Tromso" published in 2007, the researchers followed during which 60 thousand women over 40 years old, all of whom Srhan times they reached at the start of the study. And it turned out that for every move by earlier years to reach adulthood likelihood of death increases by 2.4 percent. Women that occurred normally monthly for the first time before the age of thirteen more likely she died of cancer and heart disease, stroke or other accidents by 12 percent, compared with women who have first occurred usually monthly after reaching seventeen years of age.
Norwegian research does not offer any explanation for the reasons behind these results, but other research showed likelihood of early puberty accompanied by a rise in risk of breast cancer or uterine cancer. And also took note of increased likelihood of obesity later on, is that this latter conclusion was questioned, and probably on the contrary, ie, that obesity in childhood can lead to get early adulthood.
Poor have delayed puberty
At first glance, it seems logical that a lot of kids Cavanin until satiety, and therefore weight higher than the average, grow more rapidly than kids Alnhafe, or with poor nutrition .. The reason is simply that the rich kids get food energy more able to provide growth factor on their needs.
Is that the scientific tests were conducted in 2003 by scientists from Belgium, Denmark, Finland, adding a further spectrum, where it appeared that the children begin to shift to early sexual maturity if they live a stable economic situation during the period of their development. It appeared that sexual adulthood in the developing world, on the whole, occur in the reconstruction of relatively higher, compared with the developed world or rich. And social differences in countries such as India, Cameroon and South Africa are delaying puberty, usually for a period of one year, and in some cases up the difference to three years.
The role of the obesity epidemic
Against the backdrop of this theory that talk about the role of nutrition in lowering the age of puberty, experts explain this big jump in mass decline in adulthood, which began in the sixties of the last century and continues even now. In this period, the standard of living much in developed and developing countries oil, at the same time decreased age by the first menstruation in girls so that in the United States, Norway and Finland, for example, lack
of life required to reach the first menstrual by 0.3 years per decade. Then came the era of higher standard of living became the stable, and the average age of puberty in girls is now declining by 0.1 per year. But this slow التنافص in life to reach sexual maturity does not appear to be possible to interpret sufficiency through continued improvement in the standard of living, health, forcing experts to look for other explanations for this disturbing phenomenon among boys and girls alike.
Several studies indicate that the obesity epidemic could be partly responsible for the achievement of children early. Competent Anders Juul and colleagues at the government hospital in Copenhagen conducted research on early puberty over a few years.Through frequent measurement of testes size at 1528 boy over three years (1991-1993) then (2006-2008) discovered that boys over the past fifteen years the lack of access rate to adulthood have half a year. The analyzes showed that this precocious puberty can be explained statistically by the relationship with the standard body size. And there are other international research reached the same results.
Chemistry changed hormonal balance
Is biologically not deplorable and the existence of a relationship between puberty and the standard body size, the fact that the fat stores in the body affect hormone production, which in turn plays a critical role in the launch of the process of puberty. And other indicators suggest that the increase in heft, even since the age of
breastfeeding, can affect the hormonal balance in a way that remains for life and lead to early puberty.
And raise Another theory attention, they are now talking about the impact of provocation and obstruction of functions natural work hormone of materials coming from environmental pollution, such as materials chemoprevention used in agriculture (d. D. T.), or materials are added to plastics to prevent rapid combustion such as phthalates and البيسفينول (a ). This material impact on the natural functions of hormones or interfere in the process of producing the hormone or by changing the sensitivity of fiber to be affected by hormones.
Researchers lured early puberty
Tests on animals showed that the material obstructing the work of the hormone is able to speed up the process of puberty. Belgian researcher Jean-Pierre Bourguignon showed in 2007 and 2008 that small amounts of DDT made young rats are increasing their production of the hormone GnRH, which led to the early onset of sexual maturity than usual. In 2009 researcher was able Heather Patisaul from the University of North Carolina U.S. review of the impact of substance bisfenol A on Alheibutalamos in the center of the brain when newborn rats so that stimulates early puberty them.
Yet it's difficult to know the role of inhibiting substances that disrupt the work of the hormone because of plentiful
and the fact that each and every one of them affects a different way. Dane Anders Juul and colleagues believe that the material confusing play a big role. One of their arguments came from research conducted in 2010 and which point out that recent years have witnessed in the relationship between age and the emergence of al-Sadr and the incidence of menstrual girls Aldanmarkiyat. During the fifteen years he became chest grows a full year earlier, while the menstrual progress by only 0.3 years.
This could be due to the inhibiting material, which often have an effect similar to the effect of estrogen, which affects the growth of breasts. Is that estrogen alone is unable to send the hair growth process associated with sexual maturation and menstrual process. In order to send these operations must be other hormones. According to this theory, the chest is the first stage of sexual maturity, being alone affected by hormonal imbalance, because of the effect of inhibiting substances, while the following stages, such as menstruation, less affected by the level.
And multiple stages in the process of sexual maturity creates difficulties for researchers in comparing results between different studies, to see any of the time became the earliest stages. The problem here is that there is no final agreed-upon definition of the beginning of adolescence, and for this reason Some studies stems from a moment of growth chest in girls, while others stemmed from first menstruation, which occurs three years after the start of the growth of the chest.
When the boys be increasing the size of the testes first sign to begin the process of puberty, while the same puberty occurs after two or three years. And even methods of assessment can vary internally. Some example stems from the calendar form breasts, while others examine the matter in greater depth to distinguish between real breasts and small cysts.
Family influence on early puberty
Early puberty can be a social burden on the child / children, At the same time, social relations can have an effect at the beginning of the process of puberty. More than two decades ago noted American researcher Jay Belsky of the University of Pennsylvania that children who suffer from problems in the family environment they begin sexual maturation, a natural biological reaction. This occurs as a result of hormonal changes appear due to stress. This theory has been criticized wide, but the two research papers conducted in 2005 and 2008 have strengthened this conclusion. The research was conducted on 8,000 children from the United States and Britain have shown that girls who do not live with fathers Albelogian appeared to have early menopause. The boys in the same situation also reached sexually early goals. And the presence of wolves in the house did not have any impact on the situation. And surprise that there is no impact on the children in this area, if they live with their mother in the same house or not.
Results surprise
But new research conducted in 2010 done by Julianna Deardoff from the University of California concluded that the absence of the father can accelerate puberty in children. The researcher found that the father's absence has significance only if the mother has an income high. Specialists are unable to explain this is not expected, but the prevailing belief is that low-income families multiple to seek help from relatives and friends while rich families suffering from social suffering the most in the absence of the father.
The more colorful research to get to the answer to the reasons for the decrease in the period leading up to puberty, the more it became clear over the process is controlled by a combination of factors, which depend on each other. For this reason it is still not possible now to give a simple answer to this phenomenon. And also it is still not possible to predict what it would be like if the speed of sexual maturity in the future. If the phenomenon continues to escalate in the next hundred years, it is theoretically, would mean that male children will come to adulthood and ten years of age, while girls have breasts become directly by primary education. Does that happen? And it would have him?
